A reconfigurable CMOS iinager for real-time, spatio-ternporal image processing with on-chip ADC

A low-power, CMOS imager with real-time, spatio-temporal processing capabilities is presented. An active pixel sensor array for image acquisition is coupled to an analog reconfigurable row processor which can extract both temporal and spatial features. A/D conversion is implemented on-chip at the end of each column. A 256 times 256 pixel array with a frame rate of 50 frames/sec was designed and successfully simulated both pre- and post-layout
