WM Camera's Optical Data - General Questions and Answers

Hi!
I am currently trying to extract as much optical information from cameras in WM based phones using the EXIF and WM registry. Such as tags like focal length, subject distance, zoom, etc, etc.
Currently, I am using the HTC Diamond & HTC P3600i but the basic data set is limited both from the EXIF data as well as the WM registry.
The EXIF data from the P3600i:
DateTimeDigitized: '2008:12:22 14:16:56'
ColorSpace: 65535
PixelYDimension: 1200
PixelXDimension: 1600
Flash: 0
ExifVersion: '0220'
DateTimeOriginal: '2008:12:22 14:16:56'
Artist: ' '
DateTime: '2008:12:22 14:16:56'
ResolutionUnit: 2
YResolution: 72
XResolution: 72
Model: 'P3600i'
Make: 'HTC'
Does anyone has any experience of extracting optical data from camera in the WM phones?
Thanks in advance!!!

photo resizing with pocket PC

I'm using an Orbit2(Touch Cruise), but my question relates to any pocketPC powered device.
Does anyone know of some pocketPC software that allows precise control over photo resizing ? Preferably free (failing that nag-ware). Ideally it would also allowing cropping, control over compression settings, contrast, and USM (but I know that I'm dreaming on this last point!)
I've been searching for several days, but most of the links relate to desktop software which resize down to PDA dimensions. This is not what I want - I already have plenty of software for PC's which does this.
What I want to be able to do is take a photo on the phone (3.2 MP), and then resize by an arbitrary factor
I realise that the built in picture editor allows "resizing" down to 640 by 480, but this is too small, and only applies when you're emailing and does not affect the original. It also over compresses.
The reason for my question is that the orbit 2 camera is pretty noisy, but when scaled down to about 50% using Gimp or Photoshop on the PC actually gives quite a nice image suitable for beaming / emailing.
Thanks,
Roy.
Here are the ones I tried and rejected today:
photoresize (free)
---------------
failed - converted 21 imgaes out of 31 then fell over with a memory error.
for those it did convert, all of the portrait ones were squished (lost the aspect ratio) irrespective of whether "keep aspect ratio" was checked or not.
promising (good selection of sizes, and selectable compression), but poor implementation
but could use in a pinch by creating a directory with just one or two images, and forcing their rotation to be "correct" prior to conversion
PocketPicture (free)
-------------------
seems to be a ms-paint clone.
fell over when I tried to open a large (3.1mp) image
SpbImageer ($15)
----------------
I didn't like the install process -
it wanted to act as an activesync filter, so abandoned install.
Try XnView Pocket. Unlike the name would let you believe, it is more than a viewer; it edits and resizes pictures and is free. http://www.xnviewpocket.org/

Thanks, took me a while to find it, but your review at
http://www.winmobiletech.com/PICVIEWERS/
was exactly the sort of thing I was looking for.
I note you rate xnview highly (version 1.3 in 2005)
it's now at version 1.4, and doesn't seem to have the 8MP image size restriction any more - not that I've tested that.

Sorry but this is the most I was able to find. There are a couple of upgrades to 6.1 which might (not likely) but might just have WWE versions...
I guess your best bet would be to get in touch with Pearls and see if they can help out.

Thanks for reply. But for what u gave me these links. I cannot understand. Please give me detail. How can i flash and programing it. Please .
trust that if he knew how he would've told you.
you will need to work a bit to realize this. we only support HTC devices in this forum.
flashing roms not fitting the exact device type can brick your phone.
search the internet for roms fitting your device. if you find one, we might be able to help you flash it.

PICS: N/A I have links restriction
I will add photos to this post when my links restriction is gone
Please, give me your opinion about witch one should I buy, and why
thanks!
Hi Mhz250,
I've been delivered the model you describe as "The Great One", i.e. with 1GHz processor (at least, that's what it reports) and NOT dual boot.
I can't tell you which one to buy as I'm not familiar with the others, but below are some of my impressions. As a disclaimer, the model I'd ordered was meant to be the dual boot one, so I'm a bit disgruntled, and also this is my first smart phone, so I don't have anything to compare it to with regards performance. However I do have an Ipod touch so I'm familiar with capacitive screens.
Build Quality:
The body feels reasonably solid. There's a bit of a plastic squeek when you squeeze if from the sides but otherwise there's a nice weight to it. The battery cover is metal and again feels solid.
The buttons below the screen and the two volume buttons on the side feel robust, but the cover for the memory card slot is a loose friction fit, and the small power button feels like it might eventually fall out.
Screen quality:
Brightness:
It doesn't seem as bright as my Ipod touch, even with the lightness up full. I've not tried to use it outdoors on a sunny day (I'm avoiding using it until I've my support query on sorting the dual-os settled) but for indoor use it has been fine.
Touch:
I'm using a screen protector that I ordered with the phone, which might have an effect on the responsiveness. It is a resistive screen rather than capacitive: sometimes a light touch is sufficient to get a response, other times you've got to press firmly. I'd characterise the difference like this:
- with a capacitive screen you can lightly "swoosh" with the pad of a finger to scroll
- with the S880, I find I either have to drag with the pad of my finger to scroll, or else use the tip of my finger/nail.
- in general, I find I've to re-enter my taps etc to get a response some of the time, other times it works fine.
- also bear in mind that you will not have multi-touch (pinch-to-zoom), which makes browsing less convenient.
OS:
In my opinion Windows mobile 6.5 is not very nice to use without a stylus: the settings menus and the keyboard are rather small and, although not impossible to use with the tip of your finger, it's still quite easy to select the wrong item. Note that the S880 doesn't come with one of those built-in stylus slots (or even a stylus). Installing FingerKeyboard helps with the keyboard issue, but doesn't help with the small menus.
The lack of an "alt-tab" built in to the OS to switch between running apps is a pain. Perhaps due to my unfamiliarity with the OS, I keep finding myself back at the home screen and have to re-navigate to the application (sometimes via task manager).
I downloaded a trial of SPB Mobile shell and that helps to make the screen feel more responsive. That's all very well while you're in the SPB shell (navigation) but when you finally arrive at the app, you're back in the Win6.5 world . It also adds an extra $30 to the factor into the cost, but if I cannot get the dual-os issue resolved, I'd personally go for this (and, before anyone asks, no, I'm not affiliated with SPB)
So, although this shouldn't be a review of the OS, in terms of selecting which S880 model to go for, all else being equal I'd lean towards the dual boot in order to be able to use Android. (I'm sure there are threads arguing over which OS is better, I don't mean to kick of any such debate here).
Conclusions
This is an admittedly selective review: for me, the two dominant factors are the resistive screen and the Windows interface, neither of which I particularly like, and I don't think they compliment each other.
I hope this helps!
Hi itburns!
thanks very much for such a great personal opinion! Could you test the camera for me? I really would like to know if it can take pictures at night, what's the pictures quality, real MPX of the camera.
Could you also please tell us your opinion about the speed of the phone? try to use a couple of apps at the same time and see what happends. Or a 3d game if you can!
Thanks again
Thanks for a good review! Its always nice to get personal feedback on Chinese cloned phones!
>Could you test the camera for me? I really would like to know if it can take pictures at night, what's the pictures quality, real MPX of the camera.
The camera has a popup controls dialog with the following settings
- Resolution: L, 1M, 2M, 3M
- White Balance: Auto, night, daylight, {some bizarre symbol that might mean fluorescent light}, incandescent light (a traditional lightbulb)
- EV: +/- 2 stops
- Location for storage;
- Wide-screen review
- Auto-timer
There's also a quick route to view stored pictures and a menu: the menu has
- Special Effect ( a bunch like b&w, sepia, etc)
- Snap sound
- Flash
- Iamge[sic] Quality : High Low Normal
- About: Camera V1.0
I took just a couple of shots outside at twilight and at night. Twilight ones appeared on the screen pretty close to what I was seeing. Not entirely sure what you were looking for with the night shots: they look dark, naturally! I've not viewed them on a pc yet (so no opinion on the quality) but on the phone's screen you can make out street lights etc. in the night shots
Stored as: Jpeg
Sizes: 2048 x 1246, 1600x960, 1280x768,
> Could you also please tell us your opinion about the speed of the phone?

If I'm not mistaken, apps don't run seem to concurrently in Windows Mobile: i.e. although in RAM, they remain in a sleep mode until you switch to them. This seems to be backed up by the view in task manager: CPU usage remains 0% for "running" apps. So running other apps shouldn't really affect performance other than by hogging RAM.
I've no 3D games (and anyway, as this is my first smart phone, I'd have nothing to compare with). As an aside, the phone has Teeter installed (one of those marble-around-a-maze) which, although it doesn't show off the graphics or processing, it does show off the gravity sensor and it works really well.
I did a quick scan of xda-developers for benchmarking and came across SPB Benchmark (again, I'm not affiliated with SPB!). I'll give that a run and let you know. I don't know if there are other benchmark tests worth looking at?
Hello,
You can look at the technical characteristics of Sunno S880. This smartphone model uses Marvell PXA 310 806 MHz processor but the actual CPU frequency is 624 MHz. The CPU is fast and works well with almost all applications. It can run on Windows Mobile and Android, but for now there is not a complete ROM for Android. The camera is type CMOS sensor, 1944x2592 pixels, 5MP and its quality is not different from the other Sunno Smartphone models. It depends on the environmental light, however, there are different built-in filters that improve the image quality.
Hi infobg,
thanks for that link: the model I has some differences to the one listed:
-cosmetically, the back plate looks distinctly different, while there's a slight difference on the front.
- the device information (as reported by the device itself) states
CPU Model: Marvell PXA310
CPU Speed: 1GHz
So either this is a slightly different model to the one at the link, or the information can be/is faked in WinMob Settings/Device Info.
Could you explain a bit more "for now there is not a complete ROM for Android" - I have a complaint in with my seller because the phone doesn't support Android. Is a ROM due soon, and how could I get it?
Many thanks
Hi Itburns,
the information on the website is actual. We have added a link to the Marvell PXA310 CPU specifications. It runs well up to 624 MHz, so bear in mind that Windows may not show the right information because the equipment information is recorded by the software developer. This CPU generally supports the Android core, but there isn't yet a stable version for it.
It seems we need a benchmark of your phone itburns.
infobg, I've been researching a LOT in the web and there are actually 3 models of this phone. One of them seem to be a fake, another seem to be a old model and the other is the actual model(the one with 806Mhz CPU running at 624mhz)
It seems that the first model was the one with 1Ghz processor.
Itburns, hope we can see your benchmark test soon!
Im looking to buy your s880 model
Sunno S880 Benchmark
Description
The SPB Benchmark software runs a series of separate tests under the following headings:
- Main
- Sorage Cards
- Battery
- Active Sync
Setup:
I skipped the battery test: it involves things like brining it to full power, then allowing it to run out of power, then repeating under different conditions; hadn’t got the patience.
General: - After initiating the test, I didn’t interact with the phone until the tests had run to completion.
- Connections all off: phone, Bluetooth, wifi
- Screen “lightness” set half-way and timeout for dimming set to 15 seconds.
Specific test setup- Main, File – performed with the phone powered by the mains (but with the battery also at 100% power.)
- Active Sync – performed with the phone connected to a HP laptop.
Results:
The Spb Benchmark “visualise results” didn’t work when the combined tests {Main, Storage Card, Active Sync} were in the results file, so I split out the storage card results and uploaded {Main, Active Sync}: it is possible that this could affect some of the cumulative results? Anyway I’ve copied the relevant part of the xml file below for the storage card test.
The comparand (iPaq 3650) has a 206 MHz Intel StrongARM SA-1110 32-bit RISC Processor (source ipaqrepair.co.uk)
- The “Pocket Word” and “Internet Explorer” tests did do something, I could see stuff pop up on the screen (which came alive during the test), so it is possible that the test just failed to grab the results. IT IS POSSIBLE (PROBABLE?) that the cumulative Spb Benchmark index is incomplete or unreliable, given the few failures?
- Note: for some values it would look like a low value is good (File system index?), but the hyperlinks on the spb site to explain the benchmarks seem to be broken, so I cannot be sure.
Spb Benchmark Indices
Spb Benchmark index: 463.21 (iPAQ 3650 scored 1000)

Sunno S880 Benchmark - Second test
CORRECTION: In my first posting, I said that the S880 doesn't have a built-in stylus, but I have since found it! It is very neatly hidden in the bottom right of the phone.
Ok, I've now run SKTools' benchmark. There seems to be quite a variation in the results on different runs of the tests, so this is only a snapshot and may not indicate the best or worst performance of the S880. The SKTools results usefully provide results from other phones: in the results below, I've also given results for the Touch Diamond (528MHz), Samsung Omnia II (800MHz) and HDC Touch HD2 (1GHz). Mhz250, I took a look at the video on china mobile com and the form factor of the model matches my own.
Setup as before:
- phone plugged into mains
- connections off (bluetooth, phone, wifi)
- Screen lightness mid-way, with a timeout of 15 seconds
Results:
Integer: 347 Moves / 25usec :

Sunno S880 Conclusions: Steer clear!
So, up to now I've been recording first impressions and also benchmarks. Now that I've had some time to use the Sunno S880 as a phone, it is worth adding: it's rubbish.
a) call quality is very poor - those calling me hear an echo of themselves and also complain that it's very hard to make out what I'm saying. So if you don't want to be continually be repeating yourself, avoid.
b) the phone continually loses signal, often mid call. And I'm not talking about areas of "poor reception", this happens in our capital city.
Additionally: battery life is very short, I was getting a drop of about 50% overnight with light usage (about two-three calls, 5 mins playing mah jong).
In the end, I had to cut my losses and buy the cheapest big-brand phone that I could live with, so I got a Samsung Tocco Lite. Although I'm no fan of its software interface, the call quality on the Tocco is crystal clear and there's none of the loss of signal that I was experiencing with the S880.
So I'd have to conclude: avoid the Sunno S880.
Sunno s880 pro
Hi everybody
I would like to give you my feed back about the Sunno S880pro.
First I bought this mobile phone to the website Mobino1, the shipping was fast.
1-My first surprise was that the package was a bulk ,not in a nice packet (like the samsung phone).
2-The phone in itself is nice , the screen also.
3-The problems comes when I wanted to use the phone.
The wireless, bluethoot and phone network are not stabile, I have always disconnections. An When a use the wireless, bluethoot the Battery discharges very quickly.
The Big Problem is that I cannot make a call and send SMS With the Mobile phone company "BASE" (in Belgium). So with friends we tested with anothers Mobile phone Company " Mobistar" & "Proximus",In this case the calling work well.
So I decided to change my subscription to Mobistar.
To my big surprise after two days the disconnection problems come back again.
I still have the problem actually.
I try in vain to find another ROM for this phone ,but I have not found.
If someone has the program, I m interested to have.
thank you for your understanding
sorry for my poor english
Emmanuel

[Q] Android API for GPS location

Hi,
I have Hero H7000 GSM phone with Android 2.2.1. Some application which using GPS data show speed approx. 1,9x higher then real speed. First my idea was about some mistake in sw - behaviour looks like as twice conversion from knots (nm/h) to km/h because (km/h = 1,852x nm/h)... But problem is generic for all applications using GPS data. I was use U-Blox app. for NMEA logging, and in RAW NMEA log zero speed is correctly received. But Android API provide 1,29m/s for applications. Do you have some idea where problem is locate? And idea about how to fix it?
Thanks
SDG
ACTUALIZATION: I made NMEA log (approx. 30km by car). In raw NMEA sentences captured by "u-center" is correct speed. Maximum is around 90km/h. But all applications using Android API show twice more. Please, do you have some idea about repair of this bug?

[Q] Reading RAW cards on Symbol / Motorola MC70 with DCR7000 Magnetic Stripe Reader

Hello!
tl;dr
I have an MC70 handheld computer with a DCR7000 magnetic stripe reader attachment running Windows Mobile 5.0. Do you know whether the magnetic stripe reader is able to read cards in RAW format, i.e. getting the bits on the magnetic stripe without any kind of encoding (without character encoding, parity bits, start and end sentinels or LRC)?
I've been trying using Symbol / Motorola EMDK dll libraries for .NET and Zebra DataWedge as well. No luck. There is a RAW_DECODING mode on Symbol dlls but it returns E? when reading any card in an arbitrary encoding.
-------------------------------
For those who love the detail:
Using Motorola EMDK with Symbol API (and the examples provided) I was able to develop a simple .NET application to read vanilla-formated credit cards with no problem. I'm using a custom encoding so no standard card reader would recognise my cards.
I have tried all possible MagStripe libraries in the Motorola EMDK (v2.9) [Symbol.MagStripe.dll, Symbol.MagStripe2.dll, Symbol.MagStripe.Design.dll, Symbol.MagStripe2.Design.dll and their .NET 3.5 upgraded counterparts] as well as the newer DataWedge API (v3.4 for compatibility with my device). While Symbol.MagStripe and Symbol.MagStripe.Design provide means to set the DecoderMode to RAW, the reader always returns "E?" for each track. Maybe I need to change the Track2Format property in some manner --don't really know how to use it--?
The communication between MC70 and DCR7X00 is via serial at 9600 baud, with the following command and response sequence. (in blue, commands sent by MC70; in red, sent by DCR7X00. Newlines added for clarity and sensitive information has been masked with asterisks.)
\x1B !F11001100110001\r
ack\r\n
DCR7000 rev. 1.82\r\n
Format Flags: 11001100110001\r\n
\x1B !S\r
a%B3852************^PLACEHOLDER VORNAME. ^*******************************?
b;3852************=********************?
c%******************==************************************===********************************************?\r
As the above listing shows, the format flags are default to STANDARD_DECODE with NO_LRC to be sent.
When using RAW_DECODE with NO_LRC, the format flags change as follows, but I wasn't able to read any card format. (We use only Track2. We omit Tracks 1 and 3.)
\x1B !F00010001000101\r
ack\r\n
DCR7000 rev. 1.82\r\n
Format Flags: 00010001000101\r\n
\x1B !S\r
bE?\r
The last line on the listing shows how the DCR7X00 recognises that there is data only in track 2, but is not able to decode it (E?) albeit having set the format to RAW_DECODE.
I'm confident that RAW decoding has to function properly, as I know of commercial stores using RAW decoding with the same hardware as mine. Moreover, in the DecoderModes Enumeration entry inside the EMDK Help file (EMDKfordotNET.chm):
Raw Data Decoder. The Raw Data Decoder sends magnetic data in raw data format so the application program can perform complicated decoding. With this feature, raw data, which are bit level data in the card, can be sent to the application program for further processing. Two ASCII characters represent each raw data byte. Track selection is invalid for the raw data decoder; that is, all encoded data of three tracks in the card is sent.

Finally, DataWedge has also been installed in the MC70 but after creating a profile with the DCR using library MSRMC50.dll it has trouble recognising the DCR7X00. When starting the DataWedge service in its application, it remains to IDLE. I discarded the DataWedge option after seeing the following line in the (current, not v3.4) DataWedge documentation at Zebra TechDocs:
For modifying the acquired data, DataWedge offers only the formatting options shown in the sections below. Options for formatting data beyond those shown can be found in the ID TECH SecureHead User Manual. Custom data formatting is the sole responsibility of the developer.

But ID TECH SecureHead User Manual describes a magnetic head different from the one used inside the DCR7X00 as this one encrypts data directly on the head providing Serial or USB interfaces while the one inside DCR7X00 contains seven used connections to the three different coils of the read/write head. Then the secure microcontroller inside the DCR7X00 responds with a serial command to the MC70.

Thank you very much for your time and answers .
