Image sensors for digital cameras are built with ever decreasing pixel sizes. The size of the pixels seems to be limited by technology only. However, there is also a hard theoretical limit for classical video camera systems: During a certain exposure time only a certain number of photons will reach the sensor. The resulting shot noise thus limits the signal-to-noise ratio. In this letter we show that current sensors are already surprisingly close to this limit. © 2012 SPIE and IS&T.
