Abstract
[Problem] The present disclosure proposes a technology that makes it possible to further reduce the influence of an error arising from a resolution of processing relating to measurement of the distance. [Solving Means] A sensor chip is provided which includes a light reception section configured to receive light projected from a light source and reflected by an imaging target to detect, for each given detection period, a reception light amount of the reflected light within the given period, a measurement section configured to measure a distance to the imaging object based on the reception light amount, and a control section configured to apply at least one of a first delay amount or a second delay amount, whose resolutions relating to control are different from each other, to control of a first timing at which the light reception section is to detect the reception light amount thereby to control a relative time difference between the first timing and a second timing at which the light source is to project light with a resolution finer than the resolutions of the first delay amount and the second delay amount in response to the first delay amount and the second delay amount.
