Contrast / Saturation

Postby pcarlini » Wed Jul 10, 2019 8:53 am

Hi
are contrast and saturation not available in VGA mode?

sensor.set_contrast(3)
sensor.set_saturation(3)

above code is only working if resolution set to QVGA or below.

Regards,
Pablo

Hi, in VGA mode for color we switch from using a processed image to debayering a bayer image on the fly when doing jpg compression. All the auto methods are bypassed when this happens. We have to do this because we cannot fit an RGB565 640x480 image in RAM.

We will have a new H7 camera with RAM which doesn't have this issue.
Nyamekye,
