Abstract
Input image data and a generated background image pattern are input into a selection circuit. A determination circuit determines whether the image data exceeds a predetermined threshold value, and outputs a determination signal to the selection circuit. If the determination signal indicates that the image data exceeds the threshold value, the selection circuit selects the input image data. If the determination signal indicates that the image data does not exceed the threshold value, the selection circuit selects the background image pattern, thereby replacing areas of the image data which do not exceed the threshold value with the background image pattern.
