GENERAL DESCRIPTION
The ON Semiconductor AS0142AT is a 1.0 MP CMOS digital image sensor and signal processor for automotive viewing applications. The device includes full auto−functions support (AWB and AE) and ALTM (Adaptive Local Tone Mapping) to enhance HDR image/ video. The AS0142AT implements a high−sensitivity 3.0 m pixel with DR−Pix technology and advanced noise reduction, to enable excellent low−light performance. It can be operated in either linear or high dynamic range modes. The AS0142AT may be operated in video (master) mode or in single frame trigger mode, providing flexibility for multi−camera systems.
