Abstract:
1. An image processing apparatus wherein a path of minimum pixel gradient energy is selected from among paths of pixels successively connected from top to bottom of a main image, the main image and a sub image constituting a pair of stereo images, each pixel position in the sub image corresponding to each pixel in connected pixels in the main image is calculated as an initial search point, from a stereo correspondence relationship between the main image and the sub image to be processed, a path of connected pixels in the sub image that minimizes energy obtained by summing color differences and position differences between pixels of the main image and pixels of the sub image is selected in the proximity of the initial search point, recursive search processing for optimal connected pixels is performed using energy generated by the difference between the main image and the sub image as a correction factor of pixel gradient energy of the main image, a path of connected pixels that has minimum energy is calculated from an overall value, and the composition and the horizontal and vertical size of the image are changed by inserting or deleting pixels along the path of connected pixels.
