The ON Semiconductor AS0140AT is a 1.0 MP format digital image sensor and image sensor processor for automotive viewing applications. The device includes full auto-functions support (AWB and AE) and ALTM (Adaptive Local Tone Mapping) to enhance HDRvideo. The AS0140AT implements a high-sensitivity 3.0 µm pixel with DR-Pix technology, and advanced noise reduction, to enable excellent low-light performance. It can be operated in interlaced (NTSC or PAL) or progressive modes, and captures images in eitherlinear or high dynamic range modes. The AS0140AT may be operated in video (master) mode or in single frame trigger mode, providing flexibility for multi-camera systems.
