A medium on which an image modifying program is recorded for carrying out image
processing on a computer on the basis of image data in which an image is composed
of dot-matrix pixels, thereby performing image modification is disclosed. The program
accomplishes, on the computer, a modifying parameter computing function of performing
a predetermined computing process using image data of each pixel to obtain a modifying
parameter for changing a picture quality on the basis of predetermined image processing,
a modifying parameter correcting function of obtaining an image modifying instruction
by an operator to correct the modifying parameter on the basis of the image modifying
instruction, and an image data correcting function of performing the predetermined
image processing for the image data on the basis of the modifying parameter.
