Hey Pros, there's a little bug when using the force flash code:
seq_set_prop_e_2 = $sb 04 // Forced ON, for service menu and production tests
$c9 08 // R5 camera version?
#COM_EVENT(5a,83) // Forced xenon 0b10000011, slow sync at beginning
$cl
#COM_EVENT(51,00) // Sensor scene "Auto 00"
#COM_EVENT(5a,9b) // FLASH_MODE 0b10001011: Flash on, RER off, sync on beginning.
$cx;
When switching to doc mode, #SET_REG(40,01) in doc macro is overrided, being AE_XENON_ISO 320 or wherever but only the first pic. If we semi-press the camera button for take another pic ISO is 100, but not in any other case. I putted a macro to force xenon ISO 100 if doc mode selected but it does nothing.
In two or three days I can spend time on it, but now I don't have the time. It should be very easy to force flash changing some register values in property 23, and it will be more elegant.
I just wanted to inform about that bug.
Cheers

Fixed the bug very easily just implementing FF by forcing Reg 5 to value 03 in Property 23 (00 for R5).
Cheers

1. all register are general purpose registers - some of them are used to store data, some are free or used for calculations
2. SE called them 'platform' registers
3. we have 16 registers reg0 - regF
4. probably they are 32bit registers but in compare command ($cR VV) only first 8 bits are compared
5. you can reorganize and use them as you want
in K800 driver:
// 0, Used for macros
// 1, Used for macros
// 2, Used for macros
// 3, Used for macros
in macros like COM_EVENT, SET_REG, CHANGE_MODE etc. so, they can be used for calculations but in limited way. you will loose all values in this registers if you call any code operation or event (CO&E) macro. if you will not use CO&E macro before calculations then registers can be used for normal arithmetic operations
// 4,
it's free
// 5, Used in Property 6
looks like reserved but it's not. it's free
// 6, Used for resolution ids
reserved but can be freed. resolution ID can be retrieved by command $zR (R = platform register) and then compared with ss/vf_config_NN value
// 7, Used ACM abort flag for synchronized viewfinder images.
// 8, Used to remember ISO setting since one has to change to AE_MODE to "auto" for IS.
// 9, Firmware version, checked in init_sequence
all are reserved but can be moved to different free registers
// a,
it's free
// b, Used for Flash
// c, Used for sensor scenes
all are reserved but can be moved to different free registers or squeezed to one register only
// d, 0 => normal, burst 1 => read out pict 1 ...
// e, Image stabilization 1 => ON, 0 => OFF
// f, Image format 1 => JPEG, 0 => YCbCr
all three registers are reserved but 2 of them can be freed. all values are 0 or 1 - this is normal boolean state and only 1bit value. bit operations come in handy ($bR):
$bR BB S L
R = platform register
BB = set of bits
S = index of first bit to replace
L = amount of bits to replace
this command will copy L bits from BB (from right to left). first replaced bit will be S in register R
r1 = 0bXXXXXXX
after $b1 03 2 4
r1 = 0bX0011XX (03 = in bit notification: 0b0011)

whoa........ thanks for the answers, guys... To my mind, at present time i'm newbie in cam modding.. Shit..... How you teach all it?!
How you think: a bigger file size give more quality or not?
For example, i set average size up to ~700 kilobytes, but original (from SE) average size is ~450 kilobytes.
So, 700kilobytes gives more quality then 450?
And what best value of quality compression? To my mind, 92-94%

In JPEG compression quality is given by the Q factor (but it's not standarized). The size is directly proportional to Q. In most cases, for values since Q=75 it's very difficult to see any quality difference, but this depens on the JPEG implementation. Q=90 does not mean 90% compression free. If you put it greater than Q=95, size will be several times bigger and the quality gain infinitesimal. JPEG is based on the Huffman coding (as well as gzip, mp3, png...) |

ok, and what a Q-factor param do you use?
I know that it is a variable, no constant.
If i set Q=95, 95 was a max value

I'm using "Ultimate 2.11 vivid color" right now, and color and sharpness are pretty good. But I must say it takes a lot of time comparing all available mods, so I just use them for a week or so, and then try another.
@ jomateixa: I wouldn't mind bigger files if this resulted in higher quality pics; Ultimate 2.11 pic sizes are from about 700 kB to 900kB large. Does it have the best compromize for size and quality?
@Sonarik: Could you please start a topic on how to edit language packs with the software you use? I think a lot of modders would be very grateful to you (and it would keep this topic "on topic").

file sizes are limted by the main firmware so increasing the file size beyond the limit will only make the phone crash |

i know, that the file size beyound size limit phone crash.
For example, limit for k550 - about 915-920kb

so you know the limits so try this in the k550/w610 driver for 2mp low compression
900 800
#SET_JPEG_MIN(00,00) #SET_JPEG_MAX(03,84) #SET_JPEG_AVG(03,20) #SET_JPEG_QUALITY |

thanks.
Raiderski or Kriomag - bigger file size (bigger than orginal) gives more quality, or we can not see this on photo by eyes?

It's really hard, or impossible, to see it. But it's cool | |
