Illumination control apparatus, display apparatus, display control apparatus and display control program

摘要

A display apparatus is capable of switching the operation of a backlight for illuminating a liquid crystal panel, between a synchronization mode supporting a moving image for flashing the backlight in synchronism with switching of frames of the image and a non-synchronization mode supporting a static image for flashing the backlight in asynchronism. A moving image process detecting unit detects a moving image process for displaying a moving image on a display apparatus among the processes currently being executed. A screen state monitoring unit determines that the moving image screen detected by the moving image process detecting unit is maximized and positioned at the foreground, and instructs the display apparatus to switch the backlight into the synchronization mode.
