IMAGING DEVICE, IMAGING MEANS AND PROGRAM

An imaging apparatus (1) comprises: a camera (100) (101) for generating a plurality of differently exposed images with parallax; an image brightness adjuster (200) (201) for adjusting the brightness of a plurality of images based on the exposure; a matching unit (21) (22) for using a plurality of brightness-adjusted images to perform matching between the images, and determining matching information; a distance calculator (31) for determining the distance to a given subject based on matching information; a position corrector (24) for correcting positions in an image with parallax so as to eliminate the parallax from the image with parallax, based on the matching information; and a wide dynamic range image generator (32) for combining a plurality of differently exposed images in which positions are corrected by the position corrector (24), and thereby generating an image having a wider dynamic range than images imaged by the camera (100) (101). Consequently, generation of a wide dynamic range image and measurement of the distance to a subject can be performed at the same time from differently exposed images with parallax taken at the same time.
