ABSTRACT:
An apparatus for processing an image data digitally comprises a storage device for storing therein a multiplier varying in accordance with a first image data obtained by digitally processing the image data, the length of the integral part of the first image data being n bits, a random number generating circuit for generating a random number falling on somewhere between zero and a positive number less than unity, an arithmetic circuit for performing arithmetic operations including a multiplication of the random number by the multiplier, and an adding circuit for adding the output of the arithmetic circuit to the first image data and outputting the least significant m bits (m.ltoreq.n) of the integral part of the so-added data as second image data for use in the next process.
