yea 906kb, it's limited by the main firmware i can easily increase it beyond 906 in the driver but it would just crash the cam, can't someone make a patch to remove the photo size limit. |

i'm surpised no1's done it for the k750i yet, k750i has a slower older processer with less ram, so i'm not sure if it could handle larger file sizes, the k800i is a db2020 with more ram it can view and edit 3mb 5mp pictures, so it should be able to make 1.5mb 3mp pictures with the camera. |

w810 has the same processor? (maybe even the same amouth of ram) and it can take over 800kB pictures... thats why i think its possible for k750i too  |

a raw uncompressed 2mp photo will be about 1mb in size a raw uncompressed 3mp will be about 1.5mb in size, i reccon the phones can handle this but photo saving time might be a little bit longer, but i'd rather a uncompressed. |

Killer
Anyone tried changing the 13Mhz(32C8) clockspeed to 15(3A98) or 20Mhz(4E20) ?
number
over clocking the MHZ will allow for higher fps bugless video recording but will also heat up the phone, the phone will get very hot.
-----------------------------------------------------------------------
Some chips support up to 24 mhz to 27 MHz master clock but in case but this case is different because the k800 works in 15 fps in high resolution full resolution well can do a test by increasing the frequency of the clock display screen and the frequency of recording video continues it can be a test but not exceeding the 27 mhz in both clocks, each processor chips supports a limit and am not sure what is the limit to the k800 resolutions but in the low resolutions limit is 27 MHz master clock above that value the burden on the hardware may damage.
example:
cam_i2c_address=[n]; //Micro Sensor
cam_i2c_clock_freq=[6978]; //27Mhz
cam_vf_clock_freq=0,[BB80]; //48MHz Video screen display speed
cam_ss_clock_freq=0,[32C8]; //13MHz frequency Sensitive the photos and video and high luminosity of the times the sensor camera does not support taking photos with making mistakes or overlapping photos but that each sensor works in a way
cam_ss_clock_freq_d=0,[5DC0]; //24 MHz yuv-mode formats (progressive scan)
I donīt know really what that the processor chip can be k800 works
OV3640 or MCB881 or KNC

i over clocked it to 14mhz, seems fine phones not overheating i'm not going any higher cause i fear i might damage the hardware, 21fps is too slow for video and bestpic is two slow, everything else seems fine |

over clocking it is a bad idea, it overexposes and the cam can't focus and runs to slowly. |

raw? uncompressed?
uncompressed raw 2MP is ~1mb and 3MP is ~1.5mb?
what?
sorry but you must be kidding me. i assume that your raw is not RAW
3MP jpeg with 100% quality can be ~1.5mb but this is still compressed file not raw file

well maybe not raw file i found out only DSLR cameras can produce raw images, but a 1.5mb 3mp jpeg would be nice anyway |

anything above 906kb the camera crashes anyway thats why i was saying it would require a patch because it's being limited by the main. |

Why changing of compression and increasing of file size also increase reddish colour...?
What we can do to repair colour cast...?
