Abstract: A control device includes a memory and a processor. The memory is configured to store a time comparison table. The processor is configured to determine whether a displayed image is a still image. When the displayed image is determined to be a still image, the time comparison table is queried for a corresponding still image judgment duration according to an average pixel level and a type of the still image.
