Oh, right, I forgot that it's written in python. If they're using this
library, or one whose image data converts easily, one can control
brightness and contrast of images - these are not in the hardware and
so are coarser and less useful, but are computationally cheap:
currentImage = ImageEnhance.Brightness(camera.getImage()).enhance(brightness)
processedImage = ImageEnhance.Contrast(cuerrentImage, contrast)
