IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND DATA STRUCTURE OF IMAGE FILE

摘要

Thresholds b1, b2, b3, and b4 are set in the luminance of a raw image. In an image 84a of the lowermost layer, the region in which the luminance is equal to or higher than b1 is left. In an image 84b over it, the region in which the luminance is equal to or higher than b2 is left. In an image 84c over it, the region in which the luminance is equal to or higher than b3 is left. In an image 84d of the uppermost layer, the region in which the luminance is equal to or higher than b4 is left. In each of these images, the alpha value of the other region is set to 0. The images are integrated with the color information of the raw image to generate final slice images. A display image is generated by stacking the generated slice images sequentially from the lowermost layer at predetermined intervals and performing drawing according to the point of sight.

1. An image processing device comprising:
a making-region-transparent information generator that assumes height from an image plane for an object represented in an input two-dimensional raw image and identifies a region reaching a slice plane set about the height to generate information to make a region other than the region transparent; and an image drawing section that displays an image obtained by giving a stereoscopic effect to the raw image by drawing, according to a position of a point of sight, a three-dimensional object made by stacking slice images in which part of the raw image is made transparent by using the information to make the region transparent over the raw image in a three-dimensional space according to height of the slice plane that corresponds.
