16 are covered with a red filter, 16 with a green and 16 with a blue filter. So this device has in it’s centre a 64 light sensitive cells arranged in a square grid (the small black centre square in the picture above). So any detector that needs to make sense of a world as perceived by humans needs something similar. All the colours we see are based on different mixtures and intensities of these three types of light that come through our eyes. Human eye sight works by having around 7 million light sensitive cells called cone cells,of which there are three types, one sensitive to red light, one to blue and one to green. It is surrounded by 4 bright white LED’s to try and give a consistent light level. The sensitive area is the small black square in the very middle. Sensors are available that can detect colour, these can be helpful in situations where things needed to be sorted by colour type.
