Abstract
In a ranging device for measuring a distance to an object, a distance image acquisition unit is configured to, using light reception signal, acquire a distance image that indicates, at each pixel, a distance to the object within a region illuminated with illumination light. A background light image acquisition unit is configured to, using the light reception signals, acquire a background light image that indicates an intensity of background light received at each pixel. An information acquirer is configured to acquire intensity-related information related to the intensity of the background light. A resolution controller is configured to control a resolution of the distance image and a resolution of the background light image by setting a size of pixel regions independently for each of the distance image and the background light image according to the intensity of the background light indicated by the intensity-related information.
