Abstract: PURPOSE: A device for adjusting a depth of field of a stereo image for reducing visual fatigue and a method thereof are provided to reduce visual fatigue in watching stereo images. CONSTITUTION: A stereo image input unit(21) receives right and left stereo images photographed by a camera. A variance map generator(23) selects a reference image to execute depth of field filtering from the right and left stereo images, and calculates variance to a target image based on the selected reference image for generating a variance map of the reference image. An image filter(24) executes filtering to blur an area of the reference image deviated from the depth of field based on the variation map. An image output unit(25) synthesizes the filtered reference image with the unfiltered target image to output a three-dimensional image.

Abstract: PURPOSE: An apparatus and a method for adjusting a depth of field of a stereo image is provided to reduce visual fatigue generated while watching a solid image. CONSTITUTION: According to the apparatus for adjusting a depth of field of a stereo image to reduce visual fatigue, an image input unit(21) receives a stereo left and right image photographed through a camera. A variation map generation unit(23) generates a variation map of a reference image by selecting the reference image to perform a depth of field filtering and then calculating mutation as to a target image. An image filtering unit(24) performs a filtering blurring an area out of the depth of field among the reference image based on the variation map. And an image output unit(25) synthesizes the reference image filtered through the image filtering unit and the target image which is not filtered as a three dimensional image.
