PROBLEM TO BE SOLVED: To prevent reduction in quality of a photographic image and accuracy of reading a code image, in printing based on image data including the photographic image and the code image.SOLUTION: A printer driver 22 in a computer device 20 acquires image data (object data) including a photographic image and a code image from an application 21, and binarizes the acquired image data, to detect the code image from obtained binary data. The printer driver 22 applies halftone processing to the photographic image in the acquired image data, and generates a control code (PDL) to be interpreted by a printer 100, for the detected code image, by use of data extracted from the binary data.SELECTED DRAWING: Figure 1 |
