A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
Since a CMOS sensor typically captures a row at a time within approximately 1/60 or 1/50 of a second (depending on refresh rate) it may result in a rolling shutter effect, where the image is skewed (tilted to the left or right, depending on the direction of camera or subject movement). For example, when tracking a car moving at high speed, the ...
It is perhaps the easiest to understand TDI devices by contrast with more well-known types of CCD sensors. The best known is the staring array one. In it, there are hundreds or thousands of adjacent rows of specially engineered semiconductor that react to light by accumulating charge, and slightly separated in depth from it by insulation, a tightly spaced array of gate electrodes, whose ...

The first practical semiconductor image sensor was the charge-coupled device (CCD), invented in 1969 [2] by Willard S. Boyle, who won a Nobel Prize for his work in physics. [3] Following the commercialization of CCD sensors during the late 1970s to early 1980s, the entertainment industry slowly began transitioning to digital imaging and digital ...

Current mode logic (CML), or source-coupled logic (SCL), is a digital design style used both for logic gates and for board-level digital signaling of digital data.. The basic principle of CML is that current from a constant current generator is steered between two alternate paths depending on whether a logic zero or logic one is being represented.
The ISOCELL CMOS camera sensors are a family of sensors produced by Samsung and available for purchase by other companies. They are used in a wide variety of products including mobile phones , computers and digital cameras .
