Image processing device and image processing method

摘要

Provided are an image processing device and an image processing method for generating a disparity image from a first image and a second image. A vertical edge extraction unit detects vertical edges in the first image, and a horizontal segmentation unit divides a horizontal line in the first image into a plurality of segments using the detected edges as borders between the segments. A disparity search unit calculates, for each of the segments, a disparity between the segment and a region of the second image similar to the segment, and a disparity image generation unit generates the disparity image in accordance with the disparity calculated for each of the segments.

1. An image processing device for generating a disparity image from a first image and a second image, comprising:
a memory and a processor, wherein the processor executes a program stored in the memory so as to: calculate a vertical edge component of each pixel in the first image; divide a horizontal line in the first image into a plurality of segments using, as a border between each of the segments, a pixel for which the vertical edge component has a magnitude exceeding a predetermined threshold; calculate a disparity between each of the segments and a region of the second image similar to the segment; and generate the disparity image in accordance with the disparity calculated for each of the segments.
