摘要： Provided are an image sensor and an image output method and application thereof. The image sensor includes an input circuit configured to perform a first photoelectric conversion on incident light to generate a photoelectric current in an EVS mode working period, and performs s second photoelectric conversion on the incident light to generate photoelectric charges in an APS mode working period; an EVS circuit configured to output a corresponding event signal according to a difference value between a first voltage corresponding to a photoelectric current and a reference voltage during a process of the first photoelectric conversion process; an APS circuit configured to output a corresponding grayscale signal according to a second voltage corresponding to photoelectric charges during the subsequent process of the first photoelectric conversion; and a control circuit configured to output a corresponding APS image according to the grayscale signal and output a corresponding EVS image according to the event signal. A single APS mode working period is between two adjacent EVS mode working periods. The present application not only can reduce the size of an image sensor, but also enables the output of multiple frames of EVS images while outputting one frame of APS image.

The plurality of pixels (200) include a first pixel (200a) and a second pixel (200b), which are adjacent to each other in the row direction and are connected to a common column signal line in the plurality of column signal lines (Sig), the switch element (201) of the first pixel (200a) and the switch element (201) of the second pixel (200b) are connected to drive lines different from each other in the plurality of drive lines (Vg), and the detection unit (106) determines presence/absence of radiation irradiation based on a current flowing to the bias line (Bs), the bias power supply unit includes a first bias power supply unit and a second bias power supply unit, the bias line includes a first bias line connected to the first bias power supply unit, and a second bias line connected to the second bias power supply unit and electrically independent of the first bias line, the conversion element of the first pixel is connected to the first bias power supply unit via the first bias line, and the conversion element of the second pixel is connected to the second bias power supply unit via the second bias line. The detection unit acquires a first signal value representing a current flowing to the first bias line when the switch element of a pixel in pixels whose conversion elements are connected to the first bias power supply unit in the plurality of pixels is in a conduction state, and a second signal value representing a current flowing to the second bias line when the switch element of a pixel whose conversion element is connected to the second bias power supply unit in the plurality of pixels is in a non-conduction state such that sampling timings at least partially overlap, and determines the presence/absence of radiation irradiation based on the first signal value and the second signal value.
