AR0143AT - 1/4-Inch 1.3 Mp Digital Image Sensor

AR0143AT is a 1/4−inch CMOS digital image sensor with a 1344Hx968V active−pixel array. It captures images in either linear, high dynamic range, or LFM modes, with a rolling−shutter readout. The LFM mode eliminates high frequency LED flicker in the image allowing Traffic Sign Reading (TSR) algorithms to operate in all lighting conditions. It includes sophisticated camera functions such as in−pixel binning, windowing and both video and single frame modes. It is designed for both low light and high dynamic range scene performance, with sensor fault detection features that can enable ASIL B compliance for the camera system. It is programmable through a simple two−wire serial interface. The AR0143AT produces extraordinarily clear, sharp digital pictures, and its ability to capture both continuous video and single frames makes it the perfect choice for a wide range of applications, including automotive ADAS, automotive scene viewing, and 720p HDR video.
