Image sensor
An image sensor is a device that converts an optical image into an electronic signal
image sensor
. It is employed largely in digital cameras

image sensor is an analogue device. When light hint the chip it is held as a small electrical charge in each photo sensor. The charges are converted to voltage one pixel at a time as they are read from the chip. cumulative circuitry in the camera converts the voltage into digital information.
Neither technology has a clear advantage in visualize quality. On one hand, CCD sensors are more than allergic to plum smear from bright light obtain when the sensor is overloaded; high-end CMOS sensors in turn do not suffer from this problem. On the variant hand, bargain-priced CMOS sensors are allergic to undesired perform that come as a result of rolling shutter

different hybrid CCD/CMOS architecture, transfer under the term "sCMOS," be of CMOS readout integrated travel that are single bonded to a CCD imaging substrate – a technology that was developed for invisible staring arrays

and now change to silicon-based detector technology.

Another approach is to dedicated the dead schedule dimensions available in modern CMOS technology to implement a CCD seeking organize entirely in CMOS technology. This can be achieved by separating individual poly-silicon gates by a dead small gap. These crossbred sensors are still in the research phase and can potentially stick the benefits of any CCD and CMOS imagers.
