1. An image processing device comprising at least one processor,
wherein the processor is configured to;
detect a structure of interest from a plurality of tomographic images indicating a plurality of tomographic planes of an object;
select a tomographic image including the structure of interest from the plurality of tomographic images according to a type of the structure of interest and a frequency band in a region in which the structure of interest has been detected;
generate a composite two-dimensional image by being provided with the selected tomographic image in the region in which the structure of interest has been detected by being provided with a predetermined tomographic image in a region in which the structure of interest has not been detected;
perform frequency decomposition on the plurality of tomographic images to derive a plurality of band tomographic images for each of a plurality of frequency bands including a first frequency band and a second frequency band lower than the first frequency band;
select a band tomographic image corresponding to a tomographic image, in which the structure of interest has been detected, from the plurality of band tomographic images for each pixel, which corresponds to a pixel of the composite two-dimensional image, in the plurality of band tomographic images according to the type of the structure of interest and the frequency band; and
generate the composite two-dimensional image by being provided with the selected band tomographic image in the region in which the structure of interest has been detected.
