3Major Types of Noise in Image Sensors

The most important aspect of the performance of image sensors is sensitivity as character-ized by signal-to-noise ratio (SNR). From this perspective, it is important to understand the different types of noise in image sensors. There are various types of image sensors. The main noise type and its level depend on the sensor type, each of which has its own advantages and disadvantages.

Noise disturbs the accurate reception of a signal value by overlapping with it. Various types of noise occur in the time domain (one dimensional), space domain (two dimensional), or both. Noise that fluctuates in the time domain or the time and space domain is called temporal noise, while noise that arises at the same position ...
