1 year ago By testing the board with an Arduino sketch I have come to the conclusion that somewhere during the process the ESP32-CAM board itself got damaged.
One observation using the Arduino sketch was that the faulty ESP32-CAM would take multiple 0 byte pictures before getting a full-size picture. However, the resultant picture would made up of several different partial images. This was similar to the problems I was seeing with your firmware.
On a new ESP32-CAM the your latest firmware version does produce a correct image. On the Arduino sketch there are still several 0 byte captures before the real picture. This seems normal behaviour.
Sorry about all the fuss.
Decide to go back to the example in the READ,me and play with the camera settings.
With the default conditions in the firmware I get a greenish image but it otherwise looks good.
Making camera.speffect(2) gives a b/w good image. But changing some more settings, as noted on the code snippet, gives a bar at the top.
Still seems there is a problem in making settings, ie having them take effect at the start of the capture, etc.
