Tech spec:

  • Raspberry Pi4 8G RAM
  • OS: Raspbian 10

Problem Background:

When I set resolution at camera.resolution = (4056, 3040), then at camera.start_preview(), the preview screen is completely black.

At lower resolution, I set at camera.resolution = (2592, 1944), I am able to see preview.

A bullet form the Hardware Limits section the picamera documentation:

  • The maximum resolution of the V2 camera can also cause issues with previews. Currently, picamera runs previews at the same resolution as captures (equivalent to -fp in raspistill). You may need to increase gpu_mem in /boot/config.txt to achieve full resolution operation with the V2 camera module, or configure the preview to use a lower resolution than the camera itself.
