1. An image processing device comprising: circuitry configured to: extract first feature amounts from an image to be processed; detect observation positions from the image to which attention should be paid by applying a position detection dictionary to the first feature amounts extracted from the image, wherein the position detection dictionary is generated by statistical learning in advance; extract a second feature amount from each of the detected observation positions on the image, wherein the second feature amount is a distribution of pixel luminance values in a respective observation position; determine an order of observing the observation positions on the image by applying an order generation dictionary to the distribution of pixel luminance values of the observation positions on the image, wherein the order generation dictionary is generated based on an observation log obtained by observing regions of images in the past for statistical learning; and generate observation images for displaying the observation positions on the image in the determined order.
