Abstract
A ranging device includes: a time counting unit configured to output a time count value indicating an elapsed time from a start of time counting; a light receiving unit including a plurality of pixels and configured to output a light reception count value of incident light to each of the plurality of pixels; and a pixel information generation unit configured to output pixel information in which the light reception count value and the time count value are associated with each other for each pixel. The pixel information generation unit acquires the light reception count value of each of the plurality of pixels and outputs the pixel information of each of the plurality of pixels within a period of time equal to or less than a time in which the time count value changes by a predetermined value.
