1. A system comprising:
an event-driven vision sensor including a sensor array that includes a first sensor and a second sensor arrayed in a predetermined pattern, wherein,
the first sensor and the second sensor are alternately arrayed in each of a first direction and a second direction orthogonal to the first direction, and configured to detect object movement,
the first sensor being configured to generate: (i) a first event signal when detecting a change in intensity of light larger than a first threshold, (ii) the first event signal having no different characteristics when the change in intensity of light is of a magnitude larger than any and all intensities above the first threshold, and (iii) no first event signal when the change in intensity of light is not larger than the first threshold,
the second sensor being configured to generate: (i) a second event signal when detecting a change in intensity of light larger than a second threshold that is larger than the first threshold, (ii) the second event signal having no different characteristics when the change in intensity of light is of a magnitude larger than any and all intensities above the second threshold, and (iii) no second event signal when the change in intensity of light is not larger than the second threshold; and
an information processing device including one or more processors configured to:
execute first processing when the first event signal generated by the first sensor is received and the second event signal generated by the second sensor is not received, the first processing indicating a first movement of a first object based on the change in intensity of light being larger than the first threshold; and
a execute second processing different from the first processing when the second event signal generated by the second sensor is received, the second processing indicating a second movement of a second object based on the change in intensity of light being larger than the second threshold.
