Abstract:
An expansion device includes: a thermal distension unit configured to thermally distend a thermally-expandable sheet by irradiating the thermally-expandable sheet with predetermined energy; a reading unit configured to read identifiers provided at predetermined positions of the thermally-expandable sheet; and a setting unit configured to set an amount of energy per unit area to be emitted on the thermally-expandable sheet by the thermal distension unit depending on whether (i) a second identifier as well as a first identifier has been read, or (ii) whether a predetermined part of the first identifier has been read but another part has not been read, as a result of reading the identifiers by the reading unit.
Abstract:
A photothermal conversion image generating device that generates a photothermal conversion image for forming a three-dimensional image by causing a thermally expandable sheet having a thermally expandable layer on a base material to expand, the device including: a processor that allocates, based on a line width of a line forming the three-dimensional image, an image for forming the line to either a front surface of the thermally expandable sheet or a rear surface of the thermally expandable sheet.
Abstract:
A display device, including: a storage unit in which page image data including a figure or a photograph and figure photo information are stored so as to be associated with each other for each page, the figure photo information corresponding to a figure or a photograph included in a page, being information for individually displaying the figure or the photograph and including area information which indicates an area occupied by the figure or the photograph in page image data corresponding to the page; a display unit; an operation unit; an identification unit; and a display control unit.
