It also comes from the readout circuit and eventually determines the lower detection limit of the. An image sensor or imager is a sensor that detects and conveys information used to make an. Compare figure 4 showing a ccd pcb printed circuit board with figure 5. Ccd left and cmos right color filtering image sensors register the amount of light from bright to dark with no color information. The first thing to explain is how a modern digital image sensor works. In a cob package, the chip is sealed in a resin mold, which provides high reliability and ease of use. Since cmos and ccd image sensors are color blind, a filter in front of the sensor allows the sensor to assign color tones to each pixel. Simulations and design of a singlephoton cmos imaging.
