Abstract: When receiving register setting information about a graphic on which a drawing process is carried out, a drawing control unit 10 determines whether or not a dedicated drawing unit 30 or a common drawing unit 40 is in a busy state, and, when the dedicated drawing unit or the common drawing unit is in the busy state, compares data in a register 31a or 32a or a register 40a with the register setting information. When the result of the comparison shows that an update is needed, the register setting information is stored in a command buffer 12. When the busy state is released, the register 31a or 32a or the register 40a is updated on the basis of the register setting information stored in the command buffer 12.

Abstract: A window combining device includes a window control unit for adding one window number to pixels on a window-by-window basis, a two-dimensional drawing engine for combining a drawn window including the pixels to which the window number is added by the window control unit into a display window, and a display control unit for displaying the display window into which the drawn window is combined by the two-dimensional drawing engine. When an update occurs in one of a plurality of drawn windows which construct the display window, the two-dimensional drawing engine computes an original background color from a pixel to which a blend flag showing that the pixel is a target for an antialiasing process is added, the pixel being included in pixels of the window for which the update occurs, and carries out the antialiasing process and recombines pixels into the display window.
