1. An image processing device comprising: a processor; and a memory storing computer readable instructions that, when executed by the processor, cause the processor to: acquire a normal light image that includes information within a wavelength band of white light; acquire a special light image that includes information within a specific wavelength band; perform a correction process on the special light image and generate a corrected special light image based on the special light image that is corrected; detect an attention area within the corrected special light image; and perform a blended image generation process of generating a blended image based on the normal light image and the corrected special light image, wherein the blended image generation process comprises: calculating a contribution of the corrected special light image to the blended image, wherein the contribution of the corrected special light image to the blended image is increased when the attention area has been detected within the corrected special light image as compared with the case where the attention area has not been detected within the corrected special light image; and performing at least one of a first blending process and a second blending process based on the contribution of the corrected special light image calculated, wherein the first blending process comprises blending a component G of the normal light image and a component G of the corrected special light image, and wherein the second blending process comprises blending a component B of the normal light image and a component B of the corrected special light image.
