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. |

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?

Is anyone able to provide me with a copy of 2.4 camera driver and/or any earlier versions? |

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.

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. |

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 |

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:

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
