Information processor, image data optimization method and program

摘要

Disclosed herein is an information processor including: an image storage section storing a of first image data having a first resolution and at least one piece of second image as layer-by-layer image for a specimen, the of second image data being obtained by spatially compressing the piece of first image at different magnification ratios; an image acquisition section acquiring image data from the layer-by-layer image data in units of a predetermined second resolution by which the first resolution is equally divisible to display the image data on a display device; an annotation setting section setting annotations at arbitrary spatial positions of the image data in response to an instruction the user; and an image optimization section determining whether each piece of the image data stored in the image storage section is necessary to delete the image data determined to be unnecessary.
