PURPOSE: A method for encoding an HDR(High Dynamic Range) image, a device thereof, a method for reconstructing the HDR image, a device thereof, and a recoding medium thereof are provided to arrange a down-sampling LDR(Low Dynamic Range) image and down-sampling additional data in a frame, thereby reconstructing the HDR image. CONSTITUTION: An encoding device performs down-sampling for an LDR image and additional data. The LDR image provides lower contrast ratio description of HDR image content. The additional data reconstructs an HDR image from the LDR image. The encoding device arranges a down-sampling LDR image and down-sampling additional data in a frame and encodes the frame. |
