Display control apparatus

A display control apparatus that controls a display screen of a display, the display control apparatus comprising:

• an operation receiving portion that receives, through a predetermined input device, command operation of a user for displaying a screen of predetermined application software on the display;
• a drawing processing portion that draws an application image to be displayed on the display as a screen of the application software, based on the command operation received by the operation receiving portion;
• and
• a display processing portion that generates a display image to be displayed as the display screen on the display by using the application image generated by the drawing processing portion, and displays the generated display image on the display;
• and
• a display arbitration portion that arbitrates a screen configuration of the display,
• wherein:
• a plurality of display areas is set in the display screen;
• an area rating, which indicates ranking of visibility of information for a user, is assigned in advance to each of the display areas;
• a display area, which is a display destination of a screen corresponding to the application software, is set in advance in the application software;
• the drawing processing portion is configured to draw the application image to be displayed in a display area having a higher area rating preferentially rather than the application image to be displayed in a display area having a lower area rating in the plurality of display areas;
• a load level, which indicates whether a load of the drawing processing portion for drawing the application image corresponding to the application software is high level or low level, is set in the application software;
• and
• when the operation receiving portion receives the command operation that displays a high load application image, which is the application image of the application software set in a high level in the load level, in a predetermined display area in a state where another high load application image is already displayed in another display area having an area rating higher than the area rating of the display area in which the high load application image is to be displayed, the display arbitration portion discards the command operation received at this time and keeps a present screen configuration.
