Abstract
A image generation device generates, on a print medium, an image including a first image portion and a second image portion. The device has a first screen processing unit which generates image data by an area modulation screen having a first screen ruling, for pixels of the first image portion; and a second screen processing unit which generates image data by an area modulation screen or a density modulation screen having a second screen ruling which is higher than the first screen ruling for pixels of the second image portion. And the first screen processing unit generates a halftone dot at a center of gravity position of an image of the first image portion in a cell corresponding to a halftone dot formation area in the area modulation screen processing.
