Abstract

An illumination device irradiates a field of view with pulsed illumination light. In a multi-tap type image sensor, one pixel has a plurality of FD (floating diffusion) regions. A camera controller controls a light emission timing of the illumination device and an exposure timing of the image sensor. A pulse exposure region, which is one of the plurality of FD regions, is allocated to generation of a slice image, and a continuous exposure region, which is another one of the plurality of FD regions, is allocated to generation of a normal image. The image sensor generates the slice image by performing multiple exposure of reflected light of the pulsed illumination light from the field of view using the pulse exposure region, and generates the normal image by performing exposure using the continuous exposure region in a section where the pulse exposure region is not used.
