PROBLEM TO BE SOLVED: To improve the fidelity of a reduced or enlarge image in generating the pixels of a reduced or enlarged image at a position isolated only by a value obtained by reducing a certain digit of an infinite recurring decimal or below in the inverse number of the rate of reduction or enlargement by preventing the accumulation of an error to be generated each time the distance is added according to the generation of the pixels. SOLUTION: Multipliers 3 and 4 and an adder 6 perform the arithmetic operation of Bj=Ai+1*D1+Ai*D2, and the data of input pixels Ai.Ai+1 adjacent in input pixels are weighted with a distance D1 between the generated position of a pixel Bj and the input pixel Ai+1, and the data are weighted with a distance D2 between the generated position and the input pixel Ai. When the first decimal place in the cumulative value of an error is turned into '1', a multiplication coefficient Z obtained by adding 0.1 being a correction value ADJ from a correction value generating circuit 9 by a multiplication coefficient generating circuit 8 is used as the distance D1, and 1-Z is used as the distance D2. Then, 0.1 is subtracted from the cumulative value of the error. |
