This camdriver is basically an attempt to put together good features of various modded camdrivers around esato and se-nse forums, which one camdriver has but another lacks.
First of all, I am profoundly indebted to people like Raiderski, Strong, Brazzuka, ta_power, Witchking, and many others. I could learn a lot from these people’s codes.
Let me confess that I am not a modder basically, but I can understand the camdriver code. I know some assembly language as well as high-level programming languages like C and VB.
I took the “icing on the cake” of these people’s camdrivers and made this camdriver based on the original K850 v3.7 camdriver and I currently use it. So, I thought I would share with those who are interested in it. Blessings as well as curses are welcome.
Features are:
For still camera mode:
1. Forced flash in RER
2. 4 flashes instead of 3 for RER.
3. Default sharpness 7 instead of 0 for non-doc mode scenes.
For video camera mode:
1. Video size 352 x 288
2. Night mode video fps 25
3. Manual focus in video mode
To use manual focus in video mode, switch camera into night mode. Then, EV buttons (D pad up/down) work as focus keys rather than exposure.
In non-night mode, the EV buttons work as exposure control. So, if you want to control exposure in video mode, you can first set the focus in the night mode, then turn off the night mode, and then control the exposure.
Now the video is minimally pixelated and blocky. I will post some samples of video too
NB: No another application running error, focusing difficulty, or flash firing inconsistencies

AutoChrome Camdriver for K850 Version 4.0
New feature: Manual focus in photo mode
To use manual focus in photo mode:
a) switch camera into infinity focus mode.
b) Zoom in a little (1x, 2x, etc.).
c) Press EV buttons to focus in or out.
d) After the focus is set, zoom out back to zero and click the photo
So, to sum up, if you press EV buttons when zoomed in, it works as manual focus
If you press EV buttons without zooming in, it works as exposure function.
This method serves as zoom preview also like we used to have in Raiderski camdriver for K800
Note: Always use manual focus only when infinite focus is selected or in scene modes like landscape. Otherwise, manual focus will be lost when you half-press the shutter button.
Bugfix:
Previously, exposure below zeroth level (ie. -0.2 to 0) would not work (did anybody notice that??) - Now fixed.
Improvement:
Previously, sometimes exposure found to be interfering with the manual focus by sudden brightness changes while pressing EV buttons in manual focus mode - Rewrote code to avoid this inteference

Autochrome, thats a good idea to take all the best camdriver code in one driver) if you want, i can help with testing your driver and it's next versions to improve it)) |

@Strong
Thank u Strong,
But seriously, we need more documentation as to the hardware registers in A2 phone cameras.
Do you know of any good documenation on this matter, just like we have for intel microprocessors?
@RockNRola
Thank u for testing the driver, but I do not think your photos represent the best of the driver's abilities...
ISO 100 for the close shots would not have made the the mouse picture overexposed with flash.
But thank u for trying my driver, friend

Sure, I am happy to do so:
First of all, define a macro:
MANUAL_FOCUS =
$c8 01 //if in video mode?
$p1 07 //put current value of property 7 (night mode) in register 1
$c1 01 //if night mode turned on
#COM_EVENT(06,00) //reset exposure. Otherwise, pressing EV buttons will change the exposure rather than focus
$s4 %0 //put the current ev position index in register 4
$-4 03
$*4 08
#COM_EVENT(43,$w4) //send current value in register 4 to hardware. register 43 controls the focus.
$cx
$cx
#COM_EVENT(72,00);
Then change the code in exposure section to:
seq_set_prop_0 =
#TO_DRAFT
$s5 %0 $ma 5 $-5 09
#COM_EVENT(06,$w5)
#MANUAL_FOCUS //calls the this macro every time the ev keys are pressed.

Wow, great, thanks for the quick reply...
BTW, do u already know a method to check which of the infinite/auto/macro focus is currently selected through the code in driver? I have tried some, but no success
I think if we get the datasheet for IMX020, it may be of some benefit

#COM_EVENT(43,00) MANUAL_FOCUS = 00, Infinity
auto focus defined by seq_set_prop_a and seq_get_prop_a properties
for macro you have to add flags:
seq_set_prop_9_0 = #TO_DRAFT
$sf.09 0 // Focus flag normal range
#SET_REG(6A,00); // Normal range
seq_set_prop_9_1 = #TO_DRAFT
$sf.09 1 // Focus flag full range
#SET_REG(6A,01); // Full range
flags are very useful for modding
if i am wrong somebody correct me
