Patent ID: 8773721

Claim:
An image processing apparatus, comprising: a connection unit that receives image data to be printed and image information on a type of the image data from an external device; and a pseudo-halftone processing unit that converts the image data into pseudo-halftone image data, wherein, in response to a determination that the image information received from the external device indicates that the type of the image data is a point-of-purchase advertising image based on whether the image data includes one of a product name and a price, the pseudo- halftone processing unit performs a pseudo-halftone processing on the image data at a quantization level of three or more bits on a pixel and takes a growth order causing all pixels in a high-density area to grow averagely; the pseudo-halftone processing unit performs another pseudo-halftone processing on the image data, in response to a determination that the type of the image data is not the point-of-purchase advertising image, and the another pseudo-halftone processing is different from the pseudo-halftone processing performed in response to the determination that the type of the image data is the point-of-purchase advertising image.
