Filed: 1985-11-01
Abstract: PURPOSE:To turn a digital picture obtained by a picture input device having different sampling intervals for picture digitization at an optional angle with no distortion, by sampling again the revolving angle with a parallelogram grid having the converted gradient in response to the vertical/horizontal ratio of the sampling interval of a digital picture. CONSTITUTION:For picture elements A and B adjacent to the horizontal direction of a rotary picture, a point on an original picture (b) distant from costheta in the direction (x) and a/bsintheta in the direction (y) is sampled. The elements A and B are distant from (a costheta) in the horizontal direction and (a sintheta) in the vertical direction respectively on the form surface. This is due to a fact that the horizontal and vertical directions are normalized to 1/a and 1/b on a picture memory 2. For the picture elements A and E, a point which is distant from b/asintheta in the direction (x) and costheta in the direction (y) is sampled again on the picture (b). Therefore the original picture is sampled again at a grid point of a parallelograph in general when anot equal to b is satisfied.
