IMAGING APPARATUS

摘要

An imaging apparatus includes a first imaging element that receives light having passed through a first optical element and outputs an image which has a luminance value corresponding to intensity of the light and is processed as a reference image. A second imaging element receives light having passed through a second optical element and outputs an image which has a luminance value corresponding to intensity of the light and is processed as a reference image. A distance calculation device calculates a distance image on the basis of the reference image and the comparison image, and recognition device recognizes an object on the basis of the distance image calculated by the distance calculation apparatus, in which the optical elements or the imaging elements satisfy at least one of conditions in which transmittance of the first optical element is higher than transmittance of the second optical element.
