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 includes an object image and includes information within a specific wavelength band; 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 including: an attention area detection section that detects an attention area within the corrected special light image; and a blending ratio calculation section that calculates a blending ratio based on information about the attention area detected by the attention area detection section, the blending ratio calculation section increasing the blending ratio of the corrected special light image 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, the blending section performing at least one of a first blending process and a second blending process as the blending process based on the blending ratio calculated by the blending ratio calculation section, the first blending process being a process that blends a component G of the normal light image and a component G of the corrected special light image, the second blending process being a process that blends a component B of the normal light image and a component B of the corrected special light image.
