PROBLEM TO BE SOLVED: To generate a high resolution picture with high picture quality by synthesizing a plurality of still pictures. SOLUTION: A motion vector arithmetic section 102 obtains a motion vector from two pictures [m-th, (m+1)th frames] received continuously and a layout section A 103 lays out the 2nd picture to a memory. A data processing section 104 processes pixel values of the 1st picture so that the 1st picture is well adaptive to the 2nd picture. A layout section B 105 lays out the picture that is processed in the memory in response to a vector quantity. A synthesis section 106 synthesizes the two pictures arranged in the same memory to generate one high resolution picture. The data processing section 104 generates a block A consisting of N×N pixels from the 1st picture and p-sets (p>=1) blocks in the unit of N×N pixels from the 2nd picture, applies orthogonal transform to the blocks and generates a block FK consisting of new N×N components by using the orthogonal transform coefficient. Inverse orthogonal transform is applied to the block FK and the result of transform is laid out with an offset from sampling points of the 2nd picture. The picture laid out with the offset and the 2nd picture are synthesized. |
