Light source device and electronic apparatus

An electronic apparatus comprising:

• a light source device including
• a light source unit that includes a plurality of light emitting elements and is divided into a plurality of regions having at least one light emitting element in one region, and
• an optical unit that includes a plurality of first lens groups having a first focal length and corresponding to the plurality of regions of the light source unit on a one-to-one basis, each of the plurality of first lens groups including one or more lenses, and a second lens group having a second focal length and emitting light having passed through the plurality of first lens groups, the second lens group including one or more lenses, wherein
• in the optical unit, for each of the plurality of regions,
• the first focal length is smaller than zero, the second focal length is larger than zero, and each composite focal length of each of the plurality of first lens groups and the second lens group is larger than the second focal length;
• and
• a driving unit that drives the plurality of light emitting elements to cause each of the plurality of light emitting elements to generate light.
