The table v4.0 is better because the buffer size KB is bigger


In theory this process jpeg table applies to all models that support the model OV2640 within the limits of the hardware of each model.
We will try to work first on the table jpeg to stabilise the size KB and then we can try to saturate the colors in the version Vivre Couleurs™ to try to make the colors more live and guys they can help

About Compression Jpeg

Pointing out that the chart was produced by principles of the calculations similar mode of derivation and integration by Raiderski, Magician Raider!!! O mago Raider
This clear that the larger the buffer size KB greater the likelihood of photography remain with their real information and thus not losing as much information.
This process is valid because whole basis of compression is worth the compression of signals and analysis of signals and in case of compression of video and audio MPEG and MP3 which the methods used to analyze signals and process signals.

Good job guys!

so whats the command for colour saturation (colour gain) with the OV2640 cam module with most sony cam modules it's #COM_EVENT(58,xx) with the micron cam modules it's #WRITE_IFP(25 00xx) or #REG_PAGE_CC(25 00 xx).

also how does the jpeg_qtable_factors make a difference the file size is limit by the main firmware and with the OV2640 just decreasing the jpeg compression gets alot better file sizes.

Thanks Number1

But in my opinion the limit file size or buffer size Jpeg is not determined by firmware but is determined by hardware featured by tests and studies but for each model based on the table of JPEG compression

Do u read in my post about series MT9V... Micron

You can send the photos zip compressed without changing the original resolution versions of v4.0 and v4.17? to be able to work and find a better balance and about videos as they are? Could analyze them in two resolutions at high resolution and low resolution recording the videos in conditions of good lighting dayligth and if want to analyze use the quicktime or other programm and after post the results here.

whats new? amnher
I don´t know what is happening with the driver because i have no way to ascertain how the videos are, I asked you to post or upload videos on the two resolutions recording in high brightness and if possible to show what is happening with the display, because I think that the photos can not be improved if more change the exposure appears more noise.

nice day

Do not need any special program, only the programs that support sony ericsson mobile phones are some, try for what else to adapt to you and look for a tutorial explaining how if installs driver in a...
Sometimes inside the folder are camdrivers .txt files with information on drivers and how to apply them, usually all modders developers write a readme.txt so read files .txt about camdrivers

Install folders camdrivers:
ifs/settings/camera
Install folders acousticdrivers:
ifs/settings/acoustic
Example of programs: FAR, PHONEXS + +, SETOOL

USER GUIDE INSTALL:

How to Proceed in CID 49/50/51/52... with the program *SETOOL/PHONEXS++/FAR:
*SETOOL USER GUIDE
1-Unpack the folder tpa_ifs
2-Copy in its tpa_ifs this way: ifs/settings/camera
3-Copy the file "camdriver0" the latest version to the place indicated
4-After passing your tpa_ifs compressed in *.Zip by SETOOL
5-Press the button Flash
*********
ATTENTION
*********

BEFORE YOU BEGIN INSTALL SECURITY MAKE A BACKUP OF THE CAMERA OLD VERSION DRIVER.
THIS STEP IS BASIC FOR OTHER APPLICATIONS.

good luck
