PURPOSE: An image decoding method and a device thereof are provided to reduce image decoding time by performing deblocking filtering differently according to a characteristic of an image. CONSTITUTION: A target area for performing filtering by a frame unit is configured according to a characteristic of an image(510). The characteristic of the image is at least one between size and resolution of the image. A macro block included in the target area is deblocking filtered by the frame(520). A macro block not included in the target area skips the deblocking filter(525).
