That suppresses the dark current eliminating amp glow and other patterns, Fortunately, a new technology has been developed To the commonly seen "amp glow" (Figure 1) in cameras without the new Heating one side of the sensor produces varying dark current, leading The sensor, the dark current is not uniform. Increase in temperature, so if there is a temperature gradient across Problem in older sensors is the variation of the dark current from pixel One of the big contributions of noise in long exposureĭigital camera photography is noise from dark current. With photon noise, the noise from dark current is the square root On long exposures with a digital cameras, electrons collect in the sensorĭue to thermal processes.
