Abstract
An image processing device and a method thereof are provided. In the method, an original image and a corresponding depth image are received, wherein the depth image includes a plurality of depth values, and the depth values indicate depth of field of a plurality of blocks in the original image respectively. Further, each of the blocks is processed to obtain a corresponding smoothness and/or sharpness effect according to each of the depth values. Thereby, a stereoscopic sensation of the original image can be enhanced.
