Camdriver Idea for W580i.
First of all, I'm a noob when it comes to modifying a phone but I managed to get my first phone done with no sweat. I was looking around like 3 forums and I saw something about how in the Camdriver0.dat it has something about a buffer for the picture and like percentage of the pic to degrade by to make it fit inside the buffer.
Code:
// JPEG compression (Q scaling factor) tables for JPEG retry
//
// NOTE: OV provided "Normal" (08), "High" (10), "Fine" (04)
// NOTE: Reserved Internal Registers for JPEG retry
// REG_B: 1st Qs, REG_C: 2nd Qs,
// REG_D: 3rd Qs, REG_E: last Qs,
// REG_F: retry counter
JPEG_Q_SCALE_NORMAL= $z0
$c0 01 $sb 06 $sc 0C $sd 14 $se 28 // VGA Q: 81, 62, 40, 20
$cl $c0 02 $sb 06 $sc 0C $sd 14 $se 28 // SXGA Q: 81, 62, 40, 20
$cl $c0 03 $sb 06 $sc 0C $sd 14 $se 28 // UXGA Q: 81, 62, 40, 20
$cl // not JPEG
$cx $cx $cx;
JPEG_Q_SCALE_FINE= $z0
$c0 01 $sb 01 $sc 02 $sd 04 $se 06 // VGA Q: 77, 64, 57, 21
$cl $c0 02 $sb 01 $sc 02 $sd 04 $se 06 // SXGA Q: 77, 64, 57, 21
$cl $c0 03 $sb 01 $sc 02 $sd 04 $se 06 // UXGA Q: 77, 64, 57, 21
$cl // not JPEG
$cx $cx $cx;
JPEG_Q_SCALE_NORMAL_XENON= $z0
$c0 01 $sb 0C $sc 10 $sd 28 $se 28 // VGA Q: 62, 50, 20, 20
$cl $c0 02 $sb 0C $sc 10 $sd 28 $se 28 // SXGA Q: 62, 50, 20, 20
$cl $c0 03 $sb 0C $sc 10 $sd 28 $se 28 // UXGA Q: 62, 50, 20, 20
$cl // not JPEG
$cx $cx $cx;
JPEG_Q_SCALE_FINE_XENON= $z0
$c0 01 $sb 0A $sc 10 $sd 28 $se 28 // VGA Q: 69, 50, 20, 20
$cl $c0 02 $sb 0A $sc 10 $sd 28 $se 28 // SXGA Q: 69, 50, 20, 20
$cl $c0 03 $sb 0A $sc 10 $sd 28 $se 28 // UXGA Q: 69, 50, 20, 20
$cl // not JPEG
$cx $cx $cx;
Code:
// all viewfinder (and video record)
// modes are YUV422, Y1, U, Y2, V:
cam_vf_format=E400;
// Most capture modes are JPEG
cam_ss_format=0001;
cam_ss_format_4=E400; // this one is YUV422, Y1, U, Y2, V
//-- JPEG buffer sizes (only used for ITP)
// NOTE!!! these values were copied from Clara camera driver
// TODO: get realistic values for OmniVision sensor
cam_ss_jpeg_buf_size_1=249f0; // 250 KB buffer for 640x480 JPEG snap
cam_ss_jpeg_buf_size_2=61A80; // 400 KB buffer for 1280x960 JPEG snap
cam_ss_jpeg_buf_size_3=927C0; // 650 KB buffer for 1600x1200 JPEG snap
Couldn't we beef up the buffer and change the percentage of degrading to make better pictures? I'm not totally sure but this was just an idea.
Thanks,
Buckley.
