Abstract:
1. An image data processor, comprising: an image signal receiver that receives a reference image signal, generated by an imaging device when said imaging device captures a reference image that is an optical image of an object illuminated by a reference light, and a laser image signal, generated by said imaging device when said imaging device captures a laser image that is an optical image of said object illuminated by a laser light, said laser light having a shorter average wavelength than that of said reference light; a first processing unit that generates reference edge data, corresponding to a reference edge image showing only edges, based on said reference image signal, and a laser edge data, corresponding to a laser edge image showing only edges, based on said laser image signal; and a second processing unit that detects a first partial edge shown only in one of said reference edge image and said laser edge image, based on said reference edge data and said laser edge data; wherein said second processing unit generates second partial edge data corresponding to a second partial edge image showing said reference image or said laser image, while emphasizing a first hue of said first partial edge.
