Information processing device and information processing method

The present invention suppresses an increase in power consumption. An information processing device pertaining to an embodiment comprises: hybrid-type sensors which comprise a plurality of photoelectric conversion units which perform photoelectric conversion on incident light, and a signal processing unit which acquires, on the basis of the outputs from the plurality of photoelectric conversion units, a brightness signal based on the light intensity of the incident light or an event signal based on a brightness change; a processor which performs a prescribed processing on the basis of the brightness signal or the event signal acquired by the signal processing unit; and an instruction generation unit which requires the signal processing unit to read the brightness signal, wherein when the processor fails in the prescribed processing based on the event signal, the instruction generation unit requires the signal processing unit to read the brightness signal, and the processor executes, in response to the request
