What effect does pixel size have on camera sensitivity?
Among other things, the size of the pixel directly effects the sensitivity of the camera, as well as the % of the surface area of the pixel that is capable of integrating photons of light “fill factor”. A HAN IMx-1050FT camera with a 9.9 micron square pixel will tend to be more sensitive than a HAN IMx-1040 camera with a 7.4 micron pixel. Q: What is Signal-to-Noise Ratio Top of Page A: Like most things in science, nothing is ever perfect. A CCD sensor is incapable of converting incident light exactly into an output signal. The variation from the expected output signal is referred to as noise. Noise is dependent upon such things as sensor and component quality, camera electronics design, temperature and external interference. Signal-to-Noise Ratio is usually stated in decibels (dB). The formula for calculating Signal-to-Noise in dB is SNR = 20X log(Signal/Noise) Increasing gain does not increase SNR, because it increases both the signal and the noise. Q: Define Bit Depth!
