In reproducing images in a desired magnification ratio by storing in a memory image data obtained from an original and reading out the data from the memory, moire patterns are reduced by a sampling frequency constant in accordance with a magnification ratio that yields good reproduction quality. Image data synchronized with the sampling frequency are averaged among a number of pixels corresponding to the desired magnification ratio, for storage.
