Hello, I'm trying to use mipi camera OV5640 on my custom design board, but I found the picture is not clear. The camera focus has been adjusted, and camera has been set to 1920*1080@30fps, and the picture still cannot show the word on the paper clearly, like the image shows below.
My PCB layout set clock and 2 mipi lane impedence to 100ohm , and the line length difference is not more than 30mil. Their reference plane is GND plane.
Is this the hardware(layout or SI) problem, or the camera is not good enough, or the i.MX6q driver problem?
