Abstract
An image processing device includes a processor and a memory that is connected to or provided in the processor. The processor acquires a plurality of tomographic images which indicate a plurality of tomographic planes of an object, respectively, and have a first resolution, sets a partial region of the tomographic image as a target region in a case in which an operation instruction related to interpretation is received from a user, performs a process of converting a resolution into a second resolution higher than the first resolution only on the target region to generate a high-resolution partial image of the target region, and displays the high-resolution partial image.
