Abstract
A dynamic vision sensor includes a sensor and an image signal processor. The sensor includes a pixel driver, a plurality of pixel groups, a cluster differential ADC, a cluster memory, a sensor data interface, and a controller. Each of the pixel groups includes a plurality of pixels and a floating diffusion node, each of the pixels includes a photodiode and a switch, the switch controls whether the electric charges accumulated in the photodiode are transferred to the floating diffusion node, the switch in each of the pixels is controlled by the pixel driver, and each of the pixels within a single pixel group is coupled to the floating diffusion node. The controller controls the pixel driver, the cluster differential ADC, the cluster memory, and the sensor data interface to switch between a dynamic sensing mode and a 2D image sensing mode.
