ABSTRACT:
The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPU12processes 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.
