DEVICE FOR ADJUSTING DEPTH OF FIELD OF STEREO IMAGE FOR REDUCING VISUAL FATIGUE AND METHOD THEREOF

摘要

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.
