In python module picamera, does anyone noticed that
camera.capture(array, 'rgb') is quite slow?? If you try to measure this time is about 540ms...
example code (the "real code" is irrelevant):
from picamera import PiCamera import numpy as np from time import sleep camera = PiCamera() camera.resolution = (320, 240) camera.framerate = 24 time.sleep(2) output = np.empty((240, 320, 3), dtype=np.uint8) camera.capture(output, 'rgb')
Then I use the output object to render a QWidget There is a faster way to do it?? I want something to about 16ms latency.
