also result in noise. This type of noise is called readout noise, and its amplitude
depends on the camera’s readout rate [7, 19]. Readout noise is inversely related
to the pixel readout frequency, with the power spectral density of the noise
decreasing as 1=f. Scientific-grade CCD cameras that operate in the frequency
range of 20–500 kHz typically have low readout noise that can be ignored. For
higher readout frequencies, the readout noise appears as additive, Gaussian
distributed noise that can be problematic.
12.4.1.4 Quantization Noise
All digital detectors produce quantization noise. The digitization of the CCD
image into a collection of integer values (i.e., the digital image) introduces
a form of noise that is not band-limited. Quantization noise ...
