Abstract: An image processing apparatus has a light source that emits a light signal at a predetermined time interval, a scanner capable of changing at least one of a scanning range or a scanning timing of the light signal for each of frames, a light receiver that receives a reflected light signal reflected on an object by irradiating the object with the light signal, processing circuitry that generates a distance image for each of the frames based on the reflected light signal received by the light receiver, and synthesizes the distance images of a plurality of the frames to generate a high-resolution distance image.

Abstract: An electronic apparatus has a light detector configured to detect light by converting a reception photon into a signal and incapable of converting an additional photon into the signal during a recovery period after a reception of photons, a light projector configured to project light having a pulse width different from any of n times the recovery period (n is an integer of 1 or more), and a processor configured to measure a distance to a target object by using a time difference between a timing at which light is projected by the light projector and a timing at which light comprising a reflected wave is detected by the light detector, wherein the reflected wave is obtained by reflection of the light projected by the light projector onto the target object.
