AT71200M
Description
Atmel’s AT71200M is a progressive scan sensor based on charge-coupled device
(CCD) technology. It can be used in a wide range of applications thanks to operating
mode flexibility, very high definition and high dynamic range.
The nominal photosensitive area is made up of 2300 x 3500 useful pixels and is split
into four independent zones that are driven separately by four independant four-phase
clocksets. Thus the sensor can be used in up to 12 main modes.
The large format and high definition make the device suitable for any application
requiring precision and accuracy.
The Bayer standard RGB color mosaic has been specially designed for colorimetric
applications and the three colors balanced for a 3800K standard illuminant.
Two serial registers and four independent output amplifiers offer a high-frequency
functionality of up to 10 frames per second and a 12-bit dynamic range.
