Claim One:
1. An image processing method performed by a computer, the method comprising: identifying a first depth image; upsampling the first depth image to a second depth image having an increased number of pixels compared to the first depth image; and expanding a foreground area of the upsampled second depth image by applying a dilation filter to the upsampled second depth image, wherein the upsampling is performed by interpolating the first depth image, wherein the expanding of the foreground area of the upsampled second depth image comprises expanding the foreground area by applying a dilation filter having a size that is adjusted based on characteristic information of the first depth image, wherein the dilation filter determines a pixel value of a new pixel generated by upsampling, using a highest pixel value among a pixel value corresponding to neighbor pixels, and wherein a size of the dilation filter is determined based on a resolution of the first depth image.
