Abstract
A display device according to an embodiment of the present disclosure comprises: a controller for acquiring motion information from video data, and generating result video data on the basis of a gain value corresponding to the motion information; and a display for outputting an image on the basis of the result video data, wherein the controller can acquire the result video data by applying different gain values to a motion region and a remaining region that excludes the motion region, if the area of the motion region is sensed, on the basis the motion information, as having a predetermined proportion or less to the total image area.
Claims15
A display device, comprising:
- a controller configured to obtain motion information from video data and generate result video data based on a gain value corresponding to the motion information;
- and
- a display configured to output an image based on the result video data,
- wherein the controller is configured to:
- obtain the result video data by applying different gain values to a motion area and a remaining area excluding the motion area, if the area of the motion area is detected to be less than or equal to a predetermined ratio of an entire image area based on the motion information,
- wherein the controller is configured to:
- detect a de-contour exception area that includes at least one of a high luminance area, a skin area, and a detail area, and
- not apply the gain value to the de-contour exception area.
An operating method of a display device, comprising:
- obtaining motion information from video data;
- generating result video data based on a gain value corresponding to the motion information;
- outputting an image based on the result video data, and
- wherein the generating of the result video data comprises:
- detecting whether an area of a motion area is less than or equal to a predetermined ratio of an entire image area based on the motion information;
- and
- obtaining the result video data by applying different gain values to the motion area and a remaining area excluding the motion area, if the area of the motion area is detected to be less than or equal to a predetermined ratio of the entire image area,
- wherein the generating of the result video data further comprises:
- detecting a de-contour exception area that includes at least one of a high luminance area, a skin area, and a detail area, and
- not applying the gain value to the de-contour exception area.
A display device, comprising:
- a controller configured to obtain motion information from video data and generate result video data based on a gain value corresponding to the motion information;
- a display configured to output an image based on the result video data;
- and
- a memory configured to store de-contour gain information including the gain value corresponding to the motion information,
- wherein the controller is further configured to:
- obtain the result video data by applying different gain values to a motion area and a remaining area excluding the motion area, if the area of the motion area is detected to be less than or equal to a predetermined ratio of an entire image area based on the motion information,
- wherein the de-contour gain information includes:
- a first table in which motion information and a gain value are mapped when the area of the motion area exceeds a predetermined ratio of the entire image area,
- a second table in which motion information and a gain value to be applied to the remaining area are mapped when the area of the motion area is less than or equal to a predetermined ratio of the entire image area, and
- a third table in which motion information and a gain value to be applied to the motion area are mapped when the area of the motion area is less than or equal to a predetermined ratio of the entire image area.
