it would probley take about 200kb to notice a small difference, i prefer having bigger file sizes. |

This code of a saturation #COM_EVENT(58,02) gives a real colours?
What original value of him? 00?
And what best value of contrast - 00 or 01? To my mind, for post-editing (for example, in any software for work with images - Photoshop, ACDSee...)
best is 00

#COM_EVENT(58,02) <<<#COM_EVENT(58,00) <<<
on most new se phones cid:50 and above incresing the contrast also increases the brightness/exposure causing over exposed pictures,
best value is 00, 01 gives real colours but sometimes washed out colours
01 works well in older se phones k750i/w800, older w810i.
for newer se phones best value is 00 |

pick one of your pics, open it with MS Paint, without any touching just go to File->Save as... save it with another name. you will notice that file size is about 1/3 to 1/5 of original without any noticeable diffrence. jpeg compression will remove components(higher frequencies) that human eye can't see. decreasing compression has only one advantage: higher quality after postprocessing.
for whom that don't want to do postprocessing or don't know about it, decreasing compression has not any advantage but disadvantages, bigger file size means less memory to use and longer transferring time.

Number1 is correct of course, even as a matter of using the maximum capacity that enables us to the hardware, memory because if we do not use it, but the effect of increasing the file is noticeable at resolutions up from 1.3 mb in the pictures.
The larger the file size will be the best possibility of final composition of the photograph leave better.

The postprocessing can be obtained better results depending on the response of the hardware, photos with larger files and with a good response processing that is taking less time to process it and not lose quality would be the ideal has to be a balance "equilibriun".
In fact is that the larger the file buffer better because we lost so many details of the photo.
Because if we do M2 memory card why not use it

Buffer - only for maximal photo size or for some else?
Max size of photo in my drv - 910kb. I set buffer to 1024kb. Is it a big or small?

Any body change JPEG HEADER CREATION from one driver, to other driver? I don't know, are this values are similar all on SE phones.

Filesize 910kb unless otherwise stipulated, and I believe 1024kb in programming? rigth??
The size of the files this course, the bigger better not lose anything with it but also has the limit that I think it should be by ranging from 900kb to 1000kb for each model and as a table-creation.
For the table of Rai can make sense because in other models of sony ericsson depending on the resolution the table and increase the file has no answer has no effect.
Possibly the jpeg files should be related to the videos not sure about that but I committed a mistake saying that the processing for this property cam_post_processing could accelerate or not the save of the file or buffer wherever but I am wrong because that property cam_post_processing defines the axis of rotation at 0/90/180/270 degrees degrees depending on the table, only managed to rotate the display on the video recording for horizontal but the hardware is not supported.
If you could rotate the VF display screen synchronized with the display of recording maybe could shoot pics or recording videos in horizontal and vertical but I think the hardware donīt support
One idea for you!!!
// cam_post_processing_x=
// Post processing for size configuration x:
// 0 = 0 degrees rotation
// 1 = 90 degrees clockwise rotation
// 2 = 180 degrees clockwise rotation
// 3 = 270 degrees clockwise rotation
// rotation setting for VT
cam_post_processing_19=01; // for VT 96 x 128 @ 15fps
cam_post_processing_20=01; // for VT 144 x 176 @ 15fps
//Rotation setting for VF
cam_post_processing_14=01; // for VF 320 x 240

Hey,
Have we found the K800i shutter time command yet? If not this topic might be a good way to discuse a strategy to discover it. I assume we have tried :
- Using known shutter speed command's (k850I, K750I, k550, K770, etc)
- Brute Force it? (try ALL possible commands)
- It get written to the EXIF information right? So it has to be read from memory before the phone can write it to the EXIF information.
Any other good method's? We could really use this information! |

brazuka, hardware don't support this
LaurensB, Using known shutter speed command's
#COM_EVENT(03,xx), when xx value of shutter speed in hex (1/value) * 2!
Example
#COM_EVENT(03,04) - 1/2 sec; #COM_EVENT(03,3C) - 1/30 sec; and others.......

good news, bad news...
shutter speed command equivalent:
#SET(29,xx) // shutter speed value
#CMD(02,02) // AE shutter speed priority (ISO fixed at 100)
values for xx can be found on raider.4shared.com in manual_by_SPU.html. they are for K750 but should also match in K800
at the moment this find is for nothing. you cannot build EM code in K800 because every changes (exposure, contrast, saturation etc.) in cam_ss_start are not applied! haha! ok, at least we have manual shutter speed control for supermode drivers

Your're the man !
But I did't get the bad news right....maybe because I don't know much about EM as K800 is my first.
What you mean with "applied". I see from protoptype that I set specific settings in color, ISO, focus etc. to my needs and shoot. And in the shot taken, they are applied.
Do you mean the values for "special custom programs" like for example
NIGHT Portrait (1/20, ISO 200, Focus=1.8m, color=1)
aren't called at a EV/ZoomStep combination ?
Of course with that #COM_EVENT(02,xx) must be set to wanted prority first or conflict occurs.
Edit: OK, I see there's difference between Supermode and EM. For SM it should work, I'll try that. EM I don't know but I'll try to learn....

my mistake, not everyone have to know how typical EM is working  so, small explanation...
snapshot sequence looks like this:
seq_ss_start
seq_ss_take
seq_ss_verify
seq_ss_stop
sequence with EM:
seq_ss_start <--- here #EM_SET (shutter speed calculations and setup)
seq_ss_take
seq_ss_verify
seq_ss_stop <--- here #EM_UNSET (restore no shutter speed priority AE)
in this way EM is enabled only in snapshot process as it should be
---
the problem is in seq_ss_ because you cannot change parameters in it. for example: you can add to seq_ss_start/take code to change contrast before snapshot but it won't take any effect - contrast command is 'unvisible' and not only contrast but almost everything else too 
oh crap

my top list of most irritating problems 
1. impossible changes of image parameters in seq_ss_X
2. AE lock doesn't work on landscape scenes (infinity focus)
3. AF macro range only scan doesn't exist
4. bilinear filtering (zoom) cannot be disabled
