Distance measurement and photometry apparatus

A distance measurement and photometry apparatus comprising:

• plural pairs of distance measurement sensors for obtaining information related to a distance in each of a plurality of distance measurement regions within an observation field;
• a plurality of photometry sensors located between the plural pairs of distance measurement sensors to obtain information related to brightness on each of a plurality of photometry regions provided to overlap with the plurality of distance measurement regions;
• a pair of distance measurement light receiving lenses for forming an image of a measurement object on the plural pairs of distance measurement sensors;
• and
• a photometry light receiving lens located between the pair of distance measurement light receiving lenses to form an image of the measurement object on the plurality of photometry sensors,
• wherein a distance between the plural pairs of distance measurement sensors and the pair of distance measurement light receiving lenses and a distance between the plurality of photometry sensors and the photometry light receiving lens are set such that a position of a region within the observation field in which information is obtained by the distance measurement sensors is shifted by a predetermined amount or less with respect to a position of a region within the observation field in which information is obtained by the photometry sensors irrespective of a distance to the measurement object.
