I’m using the BLIP2 board and the Image Processing toolbox. Are there any functions to directly get the scene luminance from the image? Since luminance is often measured with the cameras on smartphones when lux meters are not available, I was curious if Analog Devices already has functions to measure this. While I know there are ways to calculate luminance as a weighted sum of the RGB values, I believe there would need to be some calibration involved. Has Analog Devices already done this calibration for their image sensors?
