Display control device and method

摘要

The CPU (12) processes display area acquisition requests from a plurality of processing units (R1-Rn) according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit (R1-Rn). Each processing unit (R1-Rn) executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit (R1-Rn) after each processing unit (R1-Rn) sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit (R1-Rn) can be controlled appropriately.
