[Solved] Grab image OV7670 and store it on SD card, post processing in Python

Hi everyone,
i have attached uno to OV7670 and SD Card as shown in the schematics. I have attached the code i am using for UNO, this code grabs the frames from OV7670 and stores the pic on SD card.

There are two python code, 1st one convert the sd card(.bmp) file to (.csv) file, 2nd code convert the .csv file to (.bmp) again. which is the final picture.

The problem i am facing is that i either get a very black picture or a total white one. I am not able to get a good picture. Any help regarding this will be appreciated. Thank you.
