Abstract
A three-dimensional shadow processor adds a three-dimensional shadow having a desired length to a character image included in input image data, in a predetermined direction. Whether or not a pixel of interest is a shadow area is determined by updating, delaying and counting data representative of the remaining length of a shadow on the basis of a set length of a shadow to be generated and image data associated with the pixel of interest. In response to the result of decision, either one of input image data and shadow data is selected and outputted.
