An object of the present invention is to provide an application execution apparatus and an application execution method which enable quick startup at cold boot, and which can prevent occurrence of flicker in a display image at the time of camera image handover. The application execution apparatus according to the present invention includes a kernel that includes a display mechanism, a frame control mechanism that controls a plurality of window frames included in the display mechanism, a framework that includes an abstracted display mechanism, a first application that operates by directly using the display mechanism, and a second application that operates by indirectly using the display mechanism, and that includes a function of the first application, where the frame control mechanism performs control such that the same window frame is assigned at a time of operation of each of the first application and the second application.
