Claim One:
1. A distance measuring apparatus comprising: a light source for emitting light; an image capturing unit for capturing an image of a subject based on the light emitted from the light source and reflected from the subject; a distance information converter for converting pixel values of pixels which are obtained by the image capturing unit when the image capturing unit captures the image of the subject, into distance information representing a distance up to the subject; an image capturing condition setting section for setting first image capturing conditions based on the distance information; an image capture controller for controlling the light source and the image capturing unit to capture the image of the subject under the first image capturing conditions; and a distance measurement accuracy analyzer for analyzing a distance measurement accuracy under the first image capturing conditions and identifying an accuracy lowering distance at which the distance measurement accuracy is worse than a certain value; wherein the image capturing unit comprises a two-dimensional matrix of pixels; and the distance information converter converts each of pixel values of the pixels which are generated when the image capturing unit captures the image of the subject, into distance information to obtain one image distance data.
