Abstract: In an image processing apparatus according to a first aspect of the present invention, a first image is continuously acquired and displayed as a moving image by using first observation light until a still image acquisition instruction is received. When the still image acquisition instruction is received, a first image and a second image are acquired as still images by using first observation light and second observation light. After the still images have been acquired, a first image is acquired and displayed as a moving image again by using first observation light. Thus, the user is able to acquire still images by using first observation light and second observation light as necessary (for example, in response to a user instruction, or at a timing when acquisition of a still image is necessary such as when a region of interest is detected) while continuing observation with the first image, and is able to observe and classify a photographic subject.
