摘要： An image processing device processes an image captured by at least one image-capturing device including a lens which has characteristics of including an inflection point of a change rate of an incidence angle per image height with respect to the incidence angle at a predetermined inflection point incidence angle. The image processing device includes a resolution adjustment unit that adjusts resolution of an inflection point correspondence image area corresponding to the predetermined inflection point incidence angle and resolution of at least one of an inside image area positioned more inside than the inflection point correspondence image area and an outside image area positioned outside of the inflection point correspondence image area.

摘要： Provided is a stereo camera that is capable of reducing the distance error created by entrance pupil center movement between different principal ray angles of incidence. In the present invention, imaging system unit 100a images a standard image of an object. Imaging system unit 100b images a reference image of the object. A geometric correction information storage unit 114 stores geometric correction information for the standard image and reference image, which each have error depending on the differences between the positions of the object in the standard image and reference image if the entrance pupil center indicating the point of intersection between the principal ray and optical axis moves according to the angle of incidence and the positions of the object in the standard image and reference image if it is assumed that the entrance pupil center does not move according to the angle of incidence. The geometric correction unit 119 geometrically corrects the standard image and reference image using the geometric correction information.

摘要： The present invention provides a stereo camera in which it is possible to improve the precision of correcting vertical offset between a first image captured by a first image-capture unit and a second image captured by a second image-capture unit. In the present invention, an image-capture system unit 100a captures a benchmark image. An image-capture system unit 100b captures a reference image. A geometry correction unit 125 generates a plurality of geometry-corrected reference images having differing amounts of vertical-direction movement from the reference image. A parallax calculation unit 126 generates a plurality of parallax images from the combination of the benchmark image and each of the reference images. A parallax image evaluation unit 131 calculates evaluation values pertaining to the reliability of each of the parallax images. A vertical offset correction unit 132: calculates, on the basis of a correspondence relationship between vertical offset and the evaluation values pertaining to reliability, an evaluation value pertaining to the maximum reliability and a vertical offset that corresponds to this evaluation value; and sets the vertical offset that corresponds to the evaluation value pertaining to the maximum reliability as a vertical offset correction amount.
