Abstract
A parallax detection device receives right side image and a left side image, makes right and left low resolution images, and divides the right low resolution image into blocks composed of pixels. For every block, the device detects a parallax of the block by searching the block in the left low resolution image having the region the same as the region of the block of the right low resolution image by using a dynamic programming method. The device divides the right side image into blocks, and searches a resolution corresponding block in the left side image having the region the same as the region of the block for every block by using a block matching method to detect a parallax of the block. The device limits the searching range of the resolution corresponding block in the left side image based on the parallax detection result obtained by the dynamic programming method.
