Patent ID: 8548527

Claim:
A mobile communication terminal, comprising: a display that displays an image; an image display controller that controls the display; an application program execution manager that manages execution of an application program developed by platform-independent object-oriented programming, wherein the application program execution manager has an image data storage unit that stores image data subject to image conversion process and a drawing data storage unit that stores drawing data to display an image on a screen of the display, and wherein the image display controller controls the display so as to display an image formed of the drawing data stored in the drawing data storage unit on the screen of the display, based on an image display instruction received from the application program execution manager; an image conversion processor that can selectively execute, based on conversion-contents designating information received from the application program execution manager, a conversion process, from among a plurality of conversion processes, on the image data subject to image conversion process stored in the image data storage unit to produce converted image data, wherein the plurality of conversion processes include a drawing-type image conversion process and an effect-type image conversion process, and a drawing data generating unit that generates the drawing data from the converted image data after the selected conversion process returns the converted image data from the image conversion processor, wherein the drawing data is stored in the drawing data storage, and wherein, when the selected conversion process includes the effect-type image conversion process, the converted image data is stored in the image data store unit before the drawing data generating unit generates the drawing data, and wherein, when the selected conversion process includes only the drawing-type image conversion process, the converted image data is not stored in the image data store unit.
