Abstract
Embodiments of the present invention provide a dual-modality bionic vision sensor. A first-type current-mode active pixel sensor (APS) circuit can simulate excitatory rod cells to perceive light intensity gradient information in a target light signal, thereby improving a dynamic arrange of an image sensed by a bionic vision sensor and its shooting speed. In addition, a first-type control switch is introduced for each of non-target first-type photosensitive devices to control the obtained light intensity gradient information, and to adjust the dynamic arrange of the image sensed by the bionic vision sensor, thereby adjusting the shooting speed and realizing a reconfigurable effect. A voltage-mode APS can simulate cone cells to output a target voltage signal representing light intensity information in the target light signal, and to perceive the light intensity information in the target light signal. In this way, the obtained light intensity information represented by the target voltage signal has a higher precision, thereby ensuring the image quality.
