摘要
On a conversion plane of image data, first through third points (Q.sub. H, Q.sub.S, Q.sub.D) are provided. The first and second points are determined in accordance with highlight and shadow points of an original image, respectively, while the third point is determined in accordance with a dummy shadow point of the original image. A conversion curve (C. sub.a, C.sub.b) is so determined as to pass through the first and second points and to extend along a straight line (L) connecting the first and third points in the highlight region of the coordinate plane.
