Abstract: A vision sensor and an operating method of the vision sensor are provided. The vision sensor includes a pixel array including a plurality of pixels arranged in a form of a matrix; and a bias voltage generation circuit configured to provide a test bias voltage to the pixel array, wherein each of the plurality of pixels includes a sensing circuit configured to sense light and generate a first output voltage, wherein the first output voltage changes as the test bias voltage changes within a specific frame.

Abstract: An imaging device, image sensor and method are provided. A first scanning operation is performed on a pixel array in a first direction by a first selection circuit to generate first frame data by first readout circuit. A second scanning operation is performed on the pixel array in a second direction different from the first direction to generate second frame data by a second selection circuit. The first and second frame data are merged into single frame data by an image signal processor.
