A 0.18¿m CIS contains a QVGA array of autonomous pixels that individually detect illumination changes and communicate new gray levels that are PWM encoded after each detected change, ideally realizing optimal lossless pixel-level video compression. Readout is frame-free 18b parallel AER. SNR of >56dB and infra-scene DRs of 143dB static and 125dB at 30fps equivalent have been achieved.
