Abstract: There is provided a game device that can improve reality of a game field, by causing change in an image for a game field due to various reasons, such as change in viewpoint, with a simple method. With a game device, in display processing executed by a control section (11), rendering control section (13), display storage section (14) and display section (1), a game control section (3) carries out processing of game content performed inside a game field based on player operations, a composition rate change section (33) changes an image composition rate, a display control section (34) generates a composite image combining a plurality of image data based on the image composition rate, and a game field is displayed using the composite image.

Abstract: An image processing device capable of expressing a highlight with a relatively light processing load is provided. The device includes a light source position acquisition unit for acquiring the position of a light source, a viewpoint position and viewing direction acquisition unit (64) for acquiring a viewpoint position and a viewing direction, a highlight position calculation unit for calculating the position of a highlight appearing on the surface of an object based on the viewpoint position, a highlight intensity calculation unit for calculating intensity of the highlight based on the light source position and the viewing direction, and a semitransparent composition unit (70) for performing semitransparent composition of an image representing the highlight onto the image representing the object based on the position calculated by the highlight position calculation unit and the semitransparent composition rate corresponding to the intensity calculated by the highlight intensity calculation unit.
