Abstract:
1. An image processing device comprising: a processor; and a memory storing computer readable instructions that, when executed by the processor, implement: a normal light image acquisition section that acquires a normal light image that includes an object image and includes information within a wavelength band of white light; a special light image acquisition section that acquires a special light image that is generated from reflected narrow-band light that differs from the white light, the special light image including a component B corresponding to a surface area of the object and a component G corresponding to a deep area of the object; a correction section that performs a correction process on the special light image; and a blending section that performs a blending process that blends the normal light image and a corrected special light image that is the special light image corrected by the correction section, the blending section performing at least one of a first blending process that blends a component G of the normal light image and the component G of the corrected special light image, and a second blending process that blends a component B of the normal light image and the component B of the corrected special light image as the blending process; the blending section including: an edge extraction section that extracts at least one edge information selected from edge information about the corrected special light image and edge information about the normal light image; and a blending ratio calculation section that calculates a blending ratio based on the at least one edge information extracted by the edge extraction section, the blending section performing the blending process on the normal light image and the corrected special light image based on the blending ratio calculated by the blending ratio calculation section, the blending ratio calculation section increasing the blending ratio of the corrected special light image when the amount of edges included in the corrected special light image is large as compared with the blending ratio of the corrected special light image when the amount of edges included in the corrected special light image is small.
