Abstract
In a display apparatus where a plurality of operating systems are operated on a single processor, the plurality of operating systems share one and the same display in different display environments one example of which is a color pallet. In order to implement this configuration, the display apparatus includes the following configuration components: The plurality of operating systems, a display switching processing unit for switching the displays of the plurality of operating systems, graphics-drawing frames corresponding to the plurality of operating systems, and a display environment changing processing unit for changing, in correspondence with the display switching performed by the display switching processing unit, the display environments such as the color pallet, a color mode, and a frame address.
