Abstract
The present invention relates to an image processing apparatus for compressing image data used in an image generating apparatus for generating a free-viewpoint image. According to the invention, the apparatus has a selecting unit that selects one image as a first image, and defines other images as second images, a projective transformation unit that generates a projected depth map of a second image from a depth map of the first image, a subtracting unit that creates a difference map of the second image, and a storage unit that stores the depth map of the first image and the difference map of the second image. Here, the difference map is a difference between a depth map of the second image and the projected depth map of the second image, and the depth map indicates a depth value of each pixel of a corresponding image.
