Abstract
When an image based on RGB image data accepted by the image processing section and the ICU is to be enlarged by the zoom process section of the ICU (or when specification of an area in an image is accepted by the operation section), the leak-preventing identification mark detecting section, the positional relation calculating section and the forgery-preventing identification mark detecting section respectively determine whether patterns respectively representing a leak-preventing identification mark and a forgery-preventing identification mark are included separately in the entire area of the image and in an area to be enlarged (or an area whose specification has been accepted) or not.
Claims8
An image processing device for accepting image data including a plurality of pixel data and detecting whether two particular patterns are included in a predetermined area of an image based on accepted image data or not when the image is to be enlarged at a specified zoom level, comprising
- a detecting section for detecting whether the patterns are included separately in two areas having different sizes in the image or not.
An image processing device for accepting image data including a plurality of pixel data and detecting whether two particular patterns are included in a predetermined area of an image based on accepted image data or not, comprising:
- an accepting section for accepting specification of an area in the image;
- and
- a detecting section for detecting whether one of the two patterns is included in the area whose specification has been accepted by the accepting section or not.
