Abstract
Disclosed herein is a semiconductor integrated circuit which controls the quality of an image and includes a viewer detector, a region specifier, and a controller. The viewer detector detects the number of viewer(s) watching the image and a gaze region being watched by the viewer within the image. If the number of viewers is plural, the region specifier specifies a local region of the image as a target region based on a plurality of gaze regions being watched by the viewers. The controller performs image quality control on the target region.
Claims19
A semiconductor integrated circuit for use in a display device, the circuit comprising an output unit, an information input unit, a viewer detector, a region specifier, and a controller, wherein
- the output unit outputs output image information to the display device,
- the information input unit receives viewer information about one or more viewers, in front of the display device, watching an image on a single screen of the display device, the image being displayed based on the output image information,
- the viewer detector is configured to detect (1) how many viewers are watching the image on the single screen of the display device and (2) one or more gaze regions within the image being watched by the detected one or more viewers, based on the viewer information from the information input unit,
- the region specifier is configured to specify, in response to detecting a plurality of viewers, a target region in the image based on a plurality of gaze regions being watched by the plurality of viewers,
- the controller is configured to perform image quality control on the target region, and output the image including the target region subjected to the image quality control as the output image information to the output unit,
- the viewer detector detects a distance between the one or more viewers and the display device displaying the image, and
- the region specifier specifies the target region in consideration of the distance detected by the viewer detector as well.
A semiconductor integrated circuit for use in a display device, the circuit comprising an output unit, an information input unit, a viewer detector, a region specifier, and a controller, wherein
- the output unit outputs output image information to the display device,
- the information input unit receives viewer information about one or more viewers, in front of the display device, watching an image on a single screen of the display device, the image being displayed based on the output image information,
- the viewer detector is configured to detect (1) how many viewers are watching the image on the single screen of the display device and (2) one or more gaze regions within the image being watched by the detected one or more viewers, based on the viewer information from the information input unit,
- the region specifier is configured to specify, in response to detecting a plurality of viewers, a target region in the image based on a plurality of gaze regions being watched by the plurality of viewers,
- the controller is configured to perform image quality control on the target region, and output the image including the target region subjected to the image quality control as the output image information to the output unit, and
- if at least one of the gaze regions includes character information, the region specifier specifies the target region by excluding the at least one gaze region including the character information.
A method of controlling a quality of an image, the method comprising:
- a1) outputting output image information, by an output unit, to a display device;
- a2) receiving viewer information about one or more viewers, in front of the display device, watching the image on a single screen of the display device, the image being displayed based on the output image information;
- a3) detecting that (1) how many viewers are watching the image on the single screen of the display device and (2) a plurality of gaze regions within the image being watched by the detected one or more viewers, based on the viewer information;
- b) specifying a target region in the image based on the plurality of gaze regions being watched by the plurality of viewers;
- c) performing image quality control on the target region;
- and
- d) outputting the image including the target region subjected to the image quality control as the output image information to the output unit,
- wherein a3) includes detecting a distance between the one or more viewers, and
- wherein b) includes specifying the target region in consideration of the distance detected by the viewer detector as well.
