Claim One:
1. An image processing device for processing a plurality of time-series images taken at different points in time and arranged in chronological order, the image processing device comprising: a change-between-images calculating unit configured to: select images from the plurality of time-series images, wherein a selected image from the plurality of time-series images is a focus image, and calculate an amount-of-change-in-image for the focus image, wherein the amount-of-change-in-image indicates an amount of change between the focus image and a close image from the plurality of time-series images temporally close to the focus image; a primary-digest-image extracting unit configured to extract a plurality of primary digest images from the plurality of time-series images based on the magnitude of the amount-of-change-in-image for each focus image in the plurality of time-series images; a change-in-section calculating unit configured to: select images from the plurality of primary digest images, wherein a selected image from the plurality of primary digest images is a focus primary digest image, for the focus primary digest image, select an image from the plurality of time-series images as a late-section image, wherein the late-section image is a predetermined number of images earlier in chronological order than the focus primary digest image, and calculate an amount-of-change-in-section for the late-section image, wherein the amount-of-change-in-section indicates an amount of change between the late-section image and a preceding primary digest image from the plurality of primary digest images, the preceding primary digest image being one image earlier in chronological order than the focus primary digest image; and a digest-image extracting unit configured to extract a plurality of digest images from: the plurality of primary digest images, and the plurality of late-section images corresponding to the plurality of focus primary digest images.
