Abstract

An image processing apparatus, a computer readable medium and the like in which a dither effect in a neighborhood of a highlight area can be obtained easily and certainly. For this purpose, an image processing apparatus includes an inputting unit which inputs a pixel signal group representing a field image, an averaging unit (-and-) which performs a processing having an averaging effect among the pixel signal group input by the inputting unit, and an irregularizing unit (-) which irregularizes mutually continuous signal-values at least near a saturated level among the pixel signal group after having been processed by the averaging unit, into discontinuous signal-values.
