Claim One:
1. An image processing device which processes an image sequence that includes a plurality of constituent images, the image processing device comprising: a processor and a memory storing a program that is executable by the processor to perform an image summarization process that deletes some of the plurality of constituent images included in the image sequence to generate a summary image sequence, the image summarization process including: detecting an observation target area from each constituent image among the plurality of constituent images; selecting a reference image and a determination target image from the plurality of constituent images; calculating deformation information about a deformation estimation target area included in the reference image and the deformation estimation target area included in the determination target image; calculating an observation target coverage area by performing a deformation process using the deformation information on the observation target area included in the reference image, the observation target coverage area being an area that is included in the determination target image, and is covered by the observation target area included in the reference image; calculating an observation target common area that is a common area of the observation target coverage area and the observation target area included in the determination target image; calculating an observation target coverage that is a ratio of the calculated observation target common area with respect to the observation target area included in the determination target image; and determining whether or not the determination target image can be deleted based on the calculated observation target coverage.
