METHOD AND DEVICE FOR CONVERTING THREE-DIMENSIONAL IMAGE USING DEPTH MAP INFORMATION

摘要

One embodiment of the present invention relates to a method and a device for converting a three-dimensional image using depth map information. Provided in one embodiment of the present invention is a device for converting a three-dimensional image using depth map information comprising: a depth map estimation unit for estimating depth map information for each of the pixels present in each of the frames of the inputted image data; a depth map application unit for moving each of the pixels towards the x-axis by the value indicated in the estimated depth map information; a three-dimensional image interpolation unit for forming an interpolation pixel within an empty pixel by applying a weight value to pixels adjacent to the empty pixel when a pixel within the frame becomes empty due to the movement; and a three-dimensional image rendering processing unit for rendering a left viewing image and a right viewing image applied with the interpolation pixel. When converting a 2D image having a big change of depth map information between the adjacent pixels, such as a subtitle, into a three-dimensional image, one embodiment of the present invention can facilitate three-dimensional effects while maintaining the original shape of the object such as the corresponding letter of a subtitle.
