This modded driver it's for more sharp pictures from standard version driver 2.5...

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...

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?

@max_wedge
k750/w800/w810 have got a CMOS sensor
k800/810 have got CCD sensor
it's 2 differnet things...

CCD CMOS
System Complexity High Low
That's why K800 hasn't got any (seriously) modded camera drivers...
