Digital Camera: When you take a picture with a digital camera, a shutter
opens for a brief moment and each pixel on the image sensor records the
brightness of the light that would fall onto it. When the shutter closes to
finish the exposure it gets transferred into a number that would range from a
tone between black and white which are known as grey scale.
As the camera only records grey scale tones, RGB filters are laid on top which make the primary colours and
as each pixel goes through these colour sensitive diodes which will mix
together and will give a number which will then reveal the colour based on the
number of tones
