Methods and apparatus provide for: capturing an image of a subject from a position; capturing a plurality of images of the subject from a plurality of further positions around the position such that the plurality of captured images of the subject are at least one of different in image quality and view angles than the image of the subject from the position; generating data to be output on a basis of the image captured from the position and the plurality of images captured from the plurality of further positions; synthesizing the image captured from the position and the plurality of images captured from the plurality of further positions; and changing a synthesis ratio according to an image synthesis position.

A processor measures a first distance to an object in a distance measurement target region on the basis of an irradiation timing when a light irradiator performs surface irradiation on the distance measurement target region with light and a light receiving timing when a light receiver receives reflected light of the light from distance measurement target region. In a case in which a specific pixel included in the light receiver generates a plurality of signals at different timings within a light receiving period corresponding to the surface irradiation by the light irradiator, the processor measures the first distance on the basis of a relationship between the plurality of signals.
