Hello everyone, I have started to experiment with the OV7620 and I have a
doubt, is the NTSC output just only black and white or can it be set to
colour mode? Because when I feed the camera with 5 volts the output (VTO)
is black and white in my TV.
Thanks, Leandro.

You have read the datasheet?
VTO = Video Test Output
Considering the main function of the sensor is to provide a DIGITAL
colour output, I doubt the colour subcarrier is generated or added
to the TEST output.
Have you actually tried using an oscilloscope to look at the
output signal?

Yes, I have read the datasheet, and because of I couldn't find information
about this issue I made the question.

Probably you are wright, it's logic, thats what I imaging, but I was not
shure. Thank you!!
