The ON Semiconductor AR0221 can be operated in itsdefault mode or programmed for frame size, exposure, gain, and other parameters. The default mode output is a 1928 x1088 resolution image at 60 frames per second (fps). Inlinear mode, it outputs 12−bit raw data, using serial MIPI or HiSPi output port. In high dynamic range mode, it outputs 12−bit line−interleaved data using the MIPI or HiSPi port.The device may be operated in video (master) mode or in single frame trigger mode. FRAME_VALID, LINE_VALID and pixel clock can be programmed to output by GPIO pins in serial mode.
The AR0221 includes additional features to allow application−specific tuning: windowing and offset, auto black level correction, and on−board temperature sensor.Optional register information and histogram statistic information can be embedded in first and last two lines of the image frame. The sensor is designed to operate in a wide temperature range (−30°C to +85°C Junction). 大大通精彩博文 安森美半導體 AR0221: CMOS 影像感測器，2.1 MP，1/1.7英寸
