Abstract:
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 equal 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.
