Abstract: In combination, a detection section detects a target based on a first image signal from a first image sensor, a setting section sets an area of interest in which at least part of the target is included, a calculation section calculates, based on a second image signal from a second image sensor that asynchronously generates an image signal when a change in intensity of light incident on each of pixels is detected, a distribution of the second image signal in the area of interest, a tracking section tracks the detection target in the area of interest on the basis of at least one of the first image signal and the second image signal, a tracking controlling section discerns a movement of the detection target in the area of interest based on the tracking, and an information outputting section outputs a result of the tracking by the tracking section.

Abstract: Provided is an information processing device including a detection unit that detects a detection target on the basis of a first image signal generated by a first image sensor, a setting unit that sets a region of interest including at least a part of the detection target, a tracking unit that tracks the detection target in the region of interest on the basis of a second image signal generated by a second image sensor including an event driven vision sensor that asynchronously generates an image signal when an intensity change in light incident to each pixel is detected, and a comparison unit that compares position information on the detection target represented by a result of the detection by the detection unit on the basis of the first image signal with position information on the detection target represented by a result of the tracking by the tracking unit on the basis of the second image signal associated with the first image signal.
