Abstract
A method of enlarging or reducing an image at a desired magnification in an image reading and/or recording apparatus. The feature of the present invention resides in first deciding the integral part a and the decimal part d of a value A corresponding to the desired magnification Z, then forming a single readout pixel by averaging a pieces of basic pixels read out from an original, and subsequently using the decimal part d as a correction value for each readout pixel and deleting one basic readout pixel every time the value of the decimal part accumulated with respect to the individual readout pixels exceeds 1, thereby continuously varying the ratio of the reading resolution to the recording density to execute enlargement or reduction of the image at the desired magnification.
