PURPOSE:To deform an image which is a two-dimensional plane so that the image is made simply uneven still in the form of two-dimensional information by giving random distortion to the two-dimensional image and changing its shape. CONSTITUTION:Representative points which are separated at certain intervals are determined by 1st processing means 102 - 104 in the two-dimensional plane image, and the coordinates of those representative points are converted by using a random function to restrict the range wherein the coordinates move so that adjacent representative points interfere. When the coordinate conversion of all the representative points is completed, coordinate converting processes for points other than the representative points are performed by 2nd processing means 102, and 105 - 108. This coordinate conversion is carried out in small plane units consisting of plural adjacent representative points. Namely, the two-dimensional image is distorted at random and deformed. Consequently, the operation is easy, the amount of data which are processed decreases, and the processing speed becomes fast. |
