DISPLAY CONTROL DEVICE

摘要

A display control device includes a sift portion that sifts a transition request event stored in a queue. The sift portion monitors the queue. When the queue stores several transition request events corresponding to the same type of screen-image after transition, the sift portion retains the most recent one of the transition request events and discards the other transition request events corresponding to the same type of screen-image after transition. This can decrease transition request events stored in the queue compared to a case of not sifting transition request events and reduce a possibility of generating a delay. The sift portion does not sift a transition request event that transitions to a different type of screen-image. This can display the type of screen-image a user intends to display based on his or her manipulation.
