The output is 8-bit digital video, no dedicated pins for RGB signals.

Hi,

see Fig 11 and 12.

If you don´t understand them, then maybe it´s just a bit too early for you to access a camera.

Start with much more simpler projects.
First learn to go before try to run.

Trust the datasheet.

The information you need is in figure 11 of the data sheet. There is no Red, Green, Blue output as such, each is digitized then the digitized value is read out across two bytes as shown in the diagram. Your software/hardware has to produce the control signals to the OV7670 then at the correct time, read the bytes from the pins to reconstruct the RGB values.

The datasheet says so. Several times. Why do you ask?
