摘要：An image pickup apparatus arranged so that an optical image of an object obtained by emitting a flash is converted into an electric signal to obtain a first image regarding photographing of the object, the same optical image of the object is converted into an electric signal to obtain a second image, a distance from the object is measured for each image area of the first image on the basis of the second image, and the first image is corrected on the basis of the distance from the object measured for each image area and light distribution characteristic data of a flash stored beforehand corresponding to the distance of the object.

主权项：1. An image pickup apparatus having an image pickup unit comprising: a first obtaining unit configured to obtain a visual image converted by the image pickup unit from an optical image of an object formed by an optical unit; a second obtaining unit configured to obtain measurement signals for measuring information corresponding to distance of the object, wherein the measurement signals are generated by the image pickup unit converting optical images of the object into electric signals; a calculating unit configured to calculate a two-dimensional distribution corresponding to the distance of the object in the visual image by measuring the information using the measurement signals; a storing unit configured to store light distribution characteristic data regarding light distribution characteristics of a light emitting unit; and a correction unit configured to correct the visual image on the basis of the information included in the two-dimensional distribution calculated by the calculating unit and the light distribution characteristic data corresponding to each information included in the two-dimensional distribution.
