Here's my modded camdriver for c901.
Original colors
Modded
Changes for v0.4:
- A little programming blunder on my side created a bug that would cause overexposure. Fixed.
Changes for v0.3 are:
- Increased filesize for 5mp JPEG ( Roughly 98% compression -> 2MB )
- Better colors/saturation
- Some code changes around the driver
- Effective compression is Fine mode, selecting Normal or Fine in the camera makes no difference
Have a try and do post some pics or any issues.

Mmm...i see there was no different on both pictures.
There was some question here regarding your camdriver. How you count a jpeg compression? Because i think there is no need to increase file size without change its compression.

Compare both the pictures. The floor, the face of that female model and also the box.
The colors are abit more.... vivid.
So far as my testing goes, the original camdriver had a variable compression ratio. Using Fine mode
sometimes its 93% sometimes even 90%.
Now mostly its 98%.
What I have found out so far today is....
Using #WRITE_REG(03,0B,??) should be setting ISO. It seems that there is no effect at all to this
one.

cat photos looks good at 100% crop. But what i've found in yours camdriver in EXIF section, it seems like a wrong character goes there...(sorry if im wrong...)...please take a look at there....

you mean in this section of code??
// Property 12, EXIF 2
//----------------------------------------------------
seq_get_prop_c =
$"CAMDRIVER0: seq_get_prop_c_begin"
#READ_REG(07,2F) $m3 4 // Q-value
$cf.03 1 $s2 01 $cx // flash
#READ_REG(07,2D) $m1 4 // subject distance range
#READ_REG(06,02) // white balance
$c4 01 // auto?
$s0 00
$cl
$s0 01
¦‰ $cx
$"CAMDRIVER0: seq_get_prop_c_end_%3_%2_%1_%0"

Yupz...those line.
At 0.4 why are you remove forced flash feature?
Could you just tweak jpeg compression without change filesize?
About iso settings syntax there, i had told you before that it wasn't affect anything. C901's has drive me mad even you have succesfully rewrite it, i still didn't got its secret yet except add forced flash and increase filesize (nowaday i think it was wasteful to change filesize and buffering)

There is no way to increase % of compression yet.
Raiderski was right that any changes to the Q tables are useless... the camere uses variable tables.
Increasing the filesize will help in increasing the % of compression for now.
Forced flash has not been removed. I've moved it as a macro now.
No worries, the camdriver drives me nuts too. Still looking around and figuring things out myself.
