The image display device includes a motion detection unit for detecting a motion of a user and provides a welcome feedback to the user in the form of a visual signal, an audio signal, or both according to whether the motion of the user is detected or not, thereby drawing attention of the user or switching a display state to reduce power consumption of the image display device. The image display device determines a motion exception event that is not regarded a user motion on the basis of an overall change or a local change in pixel value between image frames, thereby preventing the display panel from being activated by a non-human-related factor such as a sudden change in illuminance or a movement of a periodically operating object.

The present invention provides a motion content based dynamic frame rate conversion method for displaying a video by a display device, comprising: detecting motion content of the video and generating a control signal for controlling a display color depth based on the motion detection result. The video is displayed with a lower color depth at a higher frame rate than a standard configuration of the display device if the motion detection result indicates that the video contains appreciable amount of motion content; and the video is displayed with a higher color depth at a lower frame rate than the standard configuration of the display device if the motion detection result indicates that the video is relatively static. The present invention can facilitate the display device to dynamically convert its display output formats according to motion content of the video to further optimize the display quality.
