PROBLEM TO BE SOLVED: To provide a raising/lowering processing method for preparing the image of a more beautiful construction material pattern by desirably raising and lowering the image of the construction material obtained as digital data. SOLUTION: A raised/lowered image is prepared by extracting prescribed low-frequency components from an original image, having a construction material pattern (S1). A form to be processed is selected from the raised/lowered image and the original image (S2, S3). A tone component is extracted from a selected raised/lowered form image, to operate to a processed form image to prepare a raised/lowered processed form image (S4). The raised/lowered image is obtained, by exchanging a image of an original form with the prepared raised/lowered processed form an image. |
