PURPOSE:To obtain a satisfactory output picture at least up to magnification corresponding to picture elements to be interpolated by interpolating between the respective picture elements when an original picture is inputted. CONSTITUTION:Picture data 20 outputted from a picture reading part 1 are developed as picture data 21 to an buffer, which is not illustrated, in an interpolation processing part 2. At this time, since the number of clocks to the interpolation processing part 2 is twice as many as that to the picture reading part 1, the picture data 20 are developed alternately as illustrated. Next, while the picture data 21 are developed to a picture memory 3 according to an address generated with the number of the clocks of a.2.fW, the picture data 21 are read from the picture memory 3 according to another address generated with the number of the clocks of b.fR and outputted to an external part with the number of the clocks of fW. When pictures twice as many or more are to be obtained, the desired number of pictures can be achieved by fixing (a) to '1' and changing (b) within the range of '0<b<1'. The enlargement ratio at this time becomes 1/b. |
