Abstract
Exposure with sufficient optical energy is enabled while avoiding temperature rise of laser light emitting elements. Therefore, a light source device includes the plurality of laser light emitting elements and a drive unit. The drive unit drives each of the laser light emitting elements to perform a plurality of light emissions in one frame period in an image sensor that receives and captures light emitted from the plurality of laser light emitting elements and reflected by a subject.
