Hi, I am currently testing an ov7670 sensor against my mx2_camera.c soc-camera driver. Everything works as expected with the exception of a green vertical line of about 6-7 pixels width that appears on the left side of the image. I suspect the problem is related to the fact that this sensor has an array of 656 x 488 pixels but only 640 x 480 are active. The datasheet available from Omnivision (Version 1.4, August 21, 2006) is not clear about how to configure the sensor not to show non active pixels but I could find the following patch which addresses a similar problem for QVGA: http://kernel.ubuntu.com/git?p=bradf/backup.ubuntu-maverick/.git;a=commitdiff;h=e4182762eaf3c80b2f5c8d1d373409d7c2843579;hp=e770cc1e35a3f11cffd1f38f52060e3e38b4fbf7 But I don't know how these values can be extrapolated to the VGA case. Has anybody found the same issue? Regards. -- Javier Martin Vista Silicon S.L. CDTUC - FASE C - Oficina S-345 Avda de los Castros s/n 39005- Santander. Cantabria.
