Raspberry Pi camera RAW image acquisition with Python

less than 1 minute read

The PiCamera Python module acquires RAW Bayer masked data from the color Raspberry Pi camera module. Getting raw Bayer images from the camera into 2592 x 1944 pixels for the V1 camera, 3280 x 2464 for the V2 camera requires a program as simple as:

import picamera
import picamera.array

with picamera.PiCamera() as cam:
    with picamera.array.PiBayerArray(cam) as stream:
        cam.capture(stream, 'jpeg', bayer=True)
        img = stream.array    

Python code for Raspberry Pi camera Bayer non-demasked image

Time to first image

It takes several seconds to load and process the first image. Acquiring an image series is much faster.
