software camera interface

Hi all,

I'm working on the example using the

Omnivision camera ov2640, but I'm not sure about the

resolution of the image coming from the camera.

I would like to configure the camera with QQVGA resolution(160x120).

I have done this configuration :

const
unsigned 
char
OV2640_QQVGA[][2]=

};

but this configuration doesn't work well .It gives me 113 lines instead of 120 lines .There is something wrong in the configuration !!

Has anyone solved this question!

below is the datasheet of tha camera omnivision 2640
