A Spatial-Temporal Multi-Resolution CMOS Image Sensor with Adaptive Frame Rates for Moving Objects in the Region-of-Interest

A CMOS image sensor simultaneously generates spatial-temporal multi-resolution images from two channels: one for normal images (<30fps) for stationary backgrounds; and the other for high-frame-rate images (adaptable to over 960fps) with reduced spatial resolution for moving objects in the region-...

Summary:A CMOS image sensor simultaneously generates spatial-temporal multi-resolution images from two channels: one for normal images (<30fps) for stationary backgrounds; and the other for high-frame-rate images (adaptable to over 960fps) with reduced spatial resolution for moving objects in the region-of-interest. This sensor employs on-chip motion detection circuits, consumes 75mW at 3.3V and is fabricated in 0.35 μm CMOS
