Abstract
Ranging sensors with reduced cyclic errors and drive current dispersion are disclosed. In one example, a ranging sensor includes a phase shift circuit that generates a phase-shifted drive pulse signal by shifting a drive pulse signal to a plurality of phases in a time division manner within one frame period, with the drive pulse signal being generated in response to a light emission control signal indicating an irradiation timing of a light emission source. A pixel accumulates electric charges on the basis of the phase-shifted drive pulse signal and outputs a detection signal corresponding to the accumulated electric charges, with the electric charges being obtained by photoelectrically converting reflected light by a predetermined object. The technology can be applied to a ranging module or the like that measures a distance to a predetermined object, for example.
