An apparatus is used to process an original digital image to obtain a uniformly scaled desired digital image, the original digital image having a number (N) of successive original image data while the desired digital image has a number (M) of successive desired image data. When (M) is greater than (N), linear interpolation of (n)th and (n+1)th ones of the original image data is performed to produce a residual interpolated image data inserted therebetween when division of (M-N) by (N-1) results in a remainder (S) and when (n) is a minimum number which meets a condition (n+1)*(S)>/=(s)*(N), wherein (s) ranges from 1 to (S). When (M) is less than (N), an address generator controls a memory unit to output selected ones of the original image data. A succeeding original image data outputted by the memory unit is offset from an immediately preceding original image data outputted thereby by a number (V) or by a number (V+1), the number (V) being equal to a quotient that results from division of (N) by (M).
