IMAGE PROCESSING DEVICE, IMAGE CAPTURE DEVICE, AND IMAGE PROCESSING PROGRAM

摘要

Provided is an image processing device, comprising: a means for receiving input of at least two disparity images, being an image of a first viewpoint direction and an image of a second viewpoint direction; a means for respectively generating, for the image of the first viewpoint direction and the image of the second viewpoint direction, a first smoothed image and a second smoothed image at least by applying a smoothing filter in a direction which joins the first and second viewpoints; a means for generating a reference image which is configured with a value based on the product of a value of the first smoothed image and a value of the second smoothed image; a means for generating gain distribution data by dividing the value of the reference image by the value of the first smoothed image; a means for carrying out a gain correction, with respect to the image of the first viewpoint direction, for each pixel on the basis of the gain distribution data; and a means for outputting the gain corrected image of the first viewpoint direction as a disparity image. The smoothing filter has a filter diameter of the same order as the degree of disparity which arises between the image of the first viewpoint direction and the image of the second viewpoint direction.
