PROBLEM TO BE SOLVED: To solve the problem in which: prediction efficiency is not improved when an error occurs in a pixel inside a block which is a not a block boundary.SOLUTION: A CTB encoding unit 102 encodes image data of the block to be encoded to generate a block code string and acquires local decoded image data of the block to be encoded. A loop filter 104 filters the local decoded image data on the basis of a filter parameter of the block to be encoded. A filter parameter encoding unit 105 encodes an acquisition flag indicating whether to acquire the filter parameter of the block to be encoded from an adjacent encoded block, and if the acquisition flag indicates that the filter parameter of the block to be encoded is not acquired from the adjacent encoded block, encodes the filter parameter of the block to be encoded. |
