A visual apparatus includes at least one set of probes and a signal generation unit. The at least one set of probes includes a plurality of probes. The signal generation unit is configured to generate a stimulation pattern signal corresponding to information on color, and to input, to at least a part of an area ranging from a retina to a visual nerve, a plurality of pattern signals as the generated stimulation pattern signal via the plurality of probes in the at least one set of probes.
