Visual stimulation method, device, equipment and program product based on non-imaging visual response

The invention provides a visual stimulation method and device based on non-imaging visual response, equipment and a program product, and relates to the technical field of electronics. Visual stimulation signals capable of triggering non-visual light stimulation are creatively applied to two visual channels of a user respectively in a time asynchronous mode. The visual channel which preferentially senses the stimulation signal enables the stimulation signal to directly stimulate the corresponding sensing channel through the photosensitive sensing cell due to non-imaging visual response. The image content of the stimulation signal needs to be perceived by the brain only after the stimulation signal is received in the other visual channel. Therefore, based on the visual stimulation method, the non-visual light stimulation and the visual image stimulation generated by the light stimulation signal are not synchronous in time, so that the mutual influence of the two processes is reduced, the stimulation effect of the non-visual light stimulation is improved, and the shaping capability of the non-visual light stimulation on a corresponding perception path is enhanced.
