Abstract

PURPOSE:To facilitate the magnification/reduction when an optional scale factor by first expanding the picture relating part or whole of the region designated on the original with the designated scale factor and then reducing the magnified picture into the desired scale factor. CONSTITUTION:When the information about the first picture element row and in the main scanning direction of the extracted region are all read out, the EOL signal is transmitted from address indication circuit 503. Circuit 503 reads out by X times the picture elements arranged in the main scanning direction within the extracted region. In other words, the original picture is magnified by X times in the main scanning direction. Shift register 509 varies the output state based on memorized correction coefficient alpha and every supply of the EOL signal. Then the information about the picture element rows arranged in the main scanning direction in the extracted region is read out by X times, and the line corresponding to coefficient alpha in the information read out is sampled or thinned.
