A 1 megapixel HDR image sensor SoC with highly parallel mixed-signal processing

This work aims to develop a universal and flexibly programmable image sensor SoC for a variety of industrial image acquisition and processing applications. It is comprised of an array of 1024x1024 pixel cells with a pitch of 8.75mm and features linear/logarithmic characteristics. In logarithmic mode, dynamic range exceeds120 dB. The fully programmable, column-parallel, mixed-signal data path from charge-based pixel readout and analogue processing via multi-slope analogue-to-digital conversion to the full custom digital 8-bit ALU allows for data processing with more than 100 GOps.
