1. A control device, comprising:
a memory configured to store a time comparison table;
a processor configured to determine whether a displayed image is a still image, and query the time comparison table for a corresponding still image judgment duration according to an average pixel level and a type of the still image when the displayed image is determined as the still image,
wherein the time comparison table stores a mapping relationship between an average pixel level and a still image judgment duration of a full-screen still image, and a mapping relationship between an average pixel level and a still image judgment duration of a window still image,
wherein the mapping relationship between the average pixel level and the still image judgment duration of the full-screen still image comprises:
if the average pixel level of the full-screen still image is less than or equal to a first threshold value, the still image judgment duration is a first value; and
if the average pixel level of the full-screen still image is greater than the first threshold value, the still image judgment duration is smaller than the first value and greater than or equal to a second value, wherein the still image judgment duration decreases as the average pixel level of the full-screen still image increases.
