Finally someone who mod K800 driver.

This message was posted from a K750i

Posted by SE4NICK
This is good news thanks for the link !

Posted by $herry
any instructions on how to update the driver? for free i.e.. any help is appreciated

Posted by max_wedge
@kopritis, thanks for that link man, like you I have cid52, so it's "have to wait" time for dcu-60 cid52 hacking. XS++ will have it soon I'm sure

I think I might buy a service cable...

The DVT cmz_config hack is another way to access file system on cid51/52 phones using dcu-60 (costs 1 davinci credit)

@$herry, not free for cid51/52, but good for K800 cid49: see this thread at se-nse:
http://forums.se-nse.net/index.php?showtopic=6805 and post there a question if K810 is supported. Someone may have tried it.

P.S. You can post photo's here to see before and after!

Some info:
I found the driver from a www site. For a days i search the code to find the sharpeness code... So i found it but the problem is that i have a k810 and i can't test the driver because my phone is CID52...

Hi kopritis you're amazing i have a question i have a k790
do you know if this camdriver works in the k790?

Posted by kopritis
@sowbran

i don't know man! I think it's the same driver but i'm not sure...

Hmmm... The only difference in this camera driver is in line 329:

Original camera driver:

#COM_EVENT(56,FF) // Reset sharpness

Modified camera driver:

#COM_EVENT(56,08) // ff Reset sharpness // 08 sharpness to max (8)

That should improve the sharpness, but it could make it too sharp...

I will try the driver and post the results tomorrow... (I've got the no-bruteforce hack installed

)
It's too dark to try it now, and I don't want to try it with night mode on

the most important hack needed for the K800 driver is to ramp down the compression somewhat. The images are way too compressed, I'd like to see a driver with less jpg compression on images.

Anyone know how to modify these lines to reduce compression:

//***************************************************
// JPEG Compression level, property 5
//***************************************************
//
// Compression Resolution Max Target Min Jpeg_first
// 0 => normal any 900 600 400 75
// 1 => low any 900 850 600 90
// 2 => normal VGA 150 55 10 75
// 3 => low VGA 150 80 10 90
// 4 => normal 1MP 400 200 60 75
// 5 => low 1MP 400 300 100 90
// 6 => normal 2MP 600 400 150 75
// 7 => low 2MP 600 500 400 90
// 8 => normal 3MP 800 600 400 75
// 9 => low 3MP 900 850 600 90
//----------------------------------------------------

For example would this be worth trying:
// 9 => low 3MP 990 940 800 95

??

Compression is already at 90% so increasing shouldn't make a noticeable difference (expect in filesize

).
It's just that the sensor sucks

And by editing these lines, you won't achieve anything, since they are just comments and they are not parsed by the phone.
If you wanted to have quality 95 instead of 90 you will probably have to edit line 562 to something like this:

#SET_REG(19,5F)

.
However, I'm not sure if that would work...

I know, but I'm just hoping something can be done. Maybe it's more a matter of changing the noise algorithms, all I know is compared to K750 the sensor must really suck if that's the best it can do!

Here's the modded compression driver, includes kopritis' sharpness mod:
http://rapidshare.com/files/46258856/camdriver0.rar.html (95% compression - instead of default 90%)

Anyone can test?

CCD CMOS
System Complexity High Low

That's why K800 hasn't got any (seriously) modded camera drivers...

Posted by Wishmaster89
k800/810 has CMOS sensor

the only

phone with CCD sensor is s700

Kopritis, I think you fell for the "cybershot" name!

As wishmaster says only S700 has CCD in camera phone!

Posted by kopritis
Yea guys you have right!!

i found this:
Camera�s module is 3.2mpx, it is made by CMOS-technology. Only 4 resolutions are supported � 3MP, 2MP, 1MP, VGA. The phone does not...........

on this site: http://www.mobile-review.com/review/sonyericsson-wilma-3-en.shtml

That's why the SE phones are cheap... cmos sensors are more cheaper from ccd sensors... (i think)

after this thread and waitting for the CID to be hacked then
everyond will say bye bye to
Super camera driver for k750/w800/w810
&
Hybrid Camera Driver for W800i/K750

and new ages of K800/k810 will start

^_^

Mongoose!, if ever you read this thread please try this on your K800. i think this is supposed to address your K800 image quality issue

Is there any chance of modding the camera driver for other phones too? especially the K610/W710/W850/S500/W580 which all have high JPEG compression

We haven't really fixed anything yet, the work has only just begun and we haven't even had any testers yet. I'll be doing the cmz_config hack soon - then I'll start testing. If advanced driver modders can then start assisting it will be great - I'll be a willing tester but I'm not as up on the drivers as some other guys.

Posted by Eternals
hi im new at this i wanna know how to put the cam driver inside my phone. do i just send it?

Posted by mongoose3800
I've done a bit of testing. It's quite frustrating. I increase the compression from 90 to 95 and I get smaller file sizes. And, increasing the max and Target File sizes causes the camera to reset when saving. I'm still playing around. Don't be affraid to test as there a several copies of the orig camdriver floating around. I'd really like to get my hands on some of the earlier versions of the camdriver.

Posted by slead
Is there actually a possibility to increase the resolution for recording videos?

I think I read for some time that the K800 is able to record videos at much higher resolution than the phone allows. It has somehow just been restricted.

Don�t know if that is the case, but if it is, would it then have anything to do with the cam driver?

Posted by max_wedge
commentry.

@slead, I strongly doubt that the resolution is artifically decreased. It's more likely to be hardware thing. I think it goes like this but I'm no expert: Video decoding and encoding is done "on chip" ie: not using software codecs in the firmware but using hardware encoders that encode on the fly. To save money in the K800, and probably size and space, the K800 wasn't given a more advanced hardware decoder so the best it can actually manage is 3GP.

That's my guess. I also base this on the fact many people reported similar rumours about K750, but no one was ever able to make it record better than it's stock (apart from a slight increase in fps). This is despite some incredible camera driver modding, you'd think they would have worked out better resolution video if it was possible.

do you tried kopritis 2.5 mod?

and any result?

Be ready for new 2.7 camera driver for k800i/810i

For free access to Fs of all CIDs at k800i/810i use the New Far manager...

I will post some pic's soon from my new mod driver to see how clear it is........

XS++ also has free access to all cids (up to 52). People should be careful with FAR, it at first appears like you can extract files from FS, but all you get is a zero byte file. So don't be thinking if you use FAR you can backup FS files. Basically FAR is good for browsing the file system, and a little easier to upload to a particular folder, but XS++ is still preferable for flashing.

Well I got my hand on the 2.4 version of the Cam Driver. Not much difference between it and 2.5. So I've continued playing around quite alot with the 2.5 version. This is what I have found. 1) You can attempt to increase the file max file size of a photo but it will result in the camera being very unstable. 2) you can change the JPG compression but I really can't see any real improvements (yet) and the jaggered lines are still there. You can go all the way to 100% if you like. But, because it seems there is something else limiting the file size it's unlikely we will see any image improvement by decreasing.

Posted by max_wedge
can you post me a driver with the changes and comments by you (where the changes are you've made)? I'll have a play with the compression. I've been taking a lot of pics and really can't seem to replicate the problem you get with jaggedness?

I haven't noticed it on other peoples pics either, but i haven't looked at many full resolution other than my own (and yours that you've posted).

I just have a feeling that maybe earlier phones, or perhaps certain batches, have this problem, but perhaps not all K800's. My sis's K800 also seems to be fine. If this is the case, you won't fix the problem with camaera driver tweaking I suspect

If it was me, I'd be hassling SE for a replacement handset.

These are the sections I've been playing with:

cam_ss_jpeg_buffer_size_1=249F0; // 150 KB buffer for 640x480 snap
cam_ss_jpeg_buffer_size_2=61A80; // 400 KB buffer for 1280x960 snap
cam_ss_jpeg_buffer_size_3=927C0; // 600 KB buffer for 1632x1244 snap
cam_ss_jpeg_buffer_size_4=DBBA0; // 900 KB buffer for 2000x1500 snap
cam_ss_jpeg_buffer_size_5=DBBA0; // 900 KB buffer for 2048x1536 snap

AND:

seq_set_prop_5_9 = $"3M_low_comp"
#SET_REG(19,5F) // JPEG_INIT_QUALITY = 0x5F = 95d
#SET_REG(13,84) #SET_REG(14,03)
#SET_REG(17,20) #SET_REG(18,03)
#SET_REG(15,58) #SET_REG(16,02);

Also, I'm quite certain the jaggedness is not just my phone. The stupid thing is that it doesn't always happen. Try taking pictures of the edge of a sheet of paper at a 45 deg angle or a barcode at 45 degrees

Posted by max_wedge
I managed to recreate the effect on a bar code, but only by washing the picture out with reflected flash.

You can see my results on flickr:
http://www.flickr.com/photos/pitdroidtech

But it proves the affect is an inherent characteristic of the hardware. It deserves continued investigation to find out what conditions specifically are causing the effect.

btw, thanks for that code

These are buffer size limits. Play with them around and check if your phone can handle 1 MB buffer or more

the more buffer size the phone can handle the lower compression you can use

Posted by max_wedge
Increased my buffer to 1MB, compression to 95%

This is a crop of a 90% picture (stock Driver):

This is a crop of a picture using 95% driver:

Now, at first glance the 95% driver seems a lot clearer, and this is exactly what I am hoping less compression can achieve. But before we get excited, I'd like to do more testing to ensure this result is easily repeatable.

Posted by mongoose3800
I have played with the buffer size. I've been able to set the buffer to 1.5mb with no problems. The catch is you can't even set the max image size to 950 without making the camera instable.

I've got a 98% driver in at the moment, with only 1MB buffer, it seems to be working okay. But I have yet to take a lot of photos with it.
