dc.description.abstractA spiking pixel to be used in image sensor arrays for asynchronous frame-based operation is presented. The pixel features both local and global adaptive sensitivity to the illumination level. Local adaptation is performed by adjusting the voltage stored in an embedded analog memory according to the average illumination within a neighborhood. Global adaptation to the overall illumination of the array is implemented by adjusting a voltage value common to all the pixels. These programming capabilities allow full control on the sensor sensitivity, pixel output data flow, and energy consumption, thus, overcoming the limitations observed in current image sensors based on spiking pixels. Experimental results validate the functionality of the proposales
