A photosite (photo/photon sensing site), as it is often termed around the web, refers to a sensor pixel in this context. Depending on the design of the sensor, a photosite or pixel may contain the necessary circuitry for a single colored pixel, or it may contain the necessary circuitry for multiple colors of pixels. When it comes to CMOS vs. CCD, they ...


Capturing three colours per photosites is in principle far superior to capturing one colour and interpolation. So much so that a three colour sensor will produce an image with equivalent detail to a one colour sensor with twice as many total pixels. Why not three times as many? Well the colour channels in an image are not independent but correlated with ...


What is actually going on? To give you a less technical and more intuitive point of view, the photo-site is governed by the photo-electric/photo-voltaic effect which was actually one of Physics' greatest mysteries, until Albert Einstein explained and consequently won his Nobel prize for explaining what was actually going on. It would not be incorrect to ...


Making the photosite itself deeper actually just reduces the low light performance as it make it so that less of the light can reach the photosite (thus decreasing how dark the scene can be before noise is a problem, but also decreasing the amount of light that gets to the sensor when it is bright, so the entire range of the camera simply shifts to brighter, ...
