IMAGE-DATA DISPLAY SYSTEM, IMAGE-DATA OUTPUT DEVICE, AND IMAGE-DATA DISPLAY METHOD

摘要

An image-data display system includes: a display-related-information acquiring unit that acquires a display size of an object image including a plane projection image of a three-dimensional object; an output-image-data generating unit that acquires instruction image data indicative of two positions in the plane projection image displayed in the object image, a length between the two positions being actual size when the object image is displayed according to the display size; and a display device that displays the object image according to the display size, and executes display processing based on the instruction image data.
