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.
