[0034] figure 1 It is a block diagram of the semiconductor integrated circuit according to the first embodiment. The semiconductor integrated circuit 10 is used to control the imaging quality of images (including moving images, etc., hereinafter referred to as images) displayed on a display device such as a television. The semiconductor integrated circuit 10 has an information input unit 12 , a display information input unit 14 , an image generation unit 16 , a viewer detection unit 18 , an area specifying unit 20 , a control unit 22 , and an output unit 24 .

[0035] Information of an image displayed on the display device is input to the information input unit 12 . This information also includes viewer information, which is information related to the viewer. The viewer information includes, for example, the number of viewers and gaze areas, and the above-mentioned viewer information can be obtained from an imaging device such as a video camera.

[0036] It should be noted ...

no. 2 approach

[0107] Figure 6 It is a schematic diagram of the display device according to the second embodiment. A display device 30 that is, for example, a digital television includes the semiconductor integrated circuit 10 according to the first embodiment, the imaging device 32 , the distance measuring sensor 34 , and the display unit 36 ​​.

[0108] The imaging device 32 is a camera or the like that captures a viewer of an image displayed on the display unit 36 ​​, and outputs viewer information to the semiconductor integrated circuit 10 .

[0109] The ranging sensor 34 measures the distance between the display device 30 and the viewer, which outputs distance information to the semiconductor integrated circuit 10 . It should be noted that the function of the distance measuring sensor 34 may also be incorporated into the imaging device 32 .

[0110] The display unit 36 ​​receives the output image information from the semiconductor integrated circuit 10, and displays an image suitable...

Abstract

The semiconductor integrated circuit (10) that controls the imaging quality of an image is equipped with: a viewer detection unit (18) that detects the number of viewers of an image and the gaze area in the image involved by the viewer; an area determination unit ( 20), in the case that the number of viewers is multiple, the area determination unit (20) converts the multiple gaze areas involved in each of the multiple viewers based on the A part of the area is determined as the object area; and a control unit (22) controls the imaging quality of the object area.

Description

technical field [0001] The present disclosure relates to a semiconductor integrated circuit used for a display device and the like, and particularly relates to a technique for reducing power consumption. Background technique [0002] In recent years, the high-definition of images displayed on display devices such as televisions and monitors has progressed. In order to realize high-quality imaging of images, it is necessary for the display device to perform a lot of processing and to have high performance. On the other hand, there arise technical problems as follows: in order to perform high-quality imaging processing, the cost of the circuit increases and the power consumption increases. In particular, the larger the screen size of the display device, the more significant the increase in cost and power consumption. [0003] Then, a method of performing required processing not on the entire screen but on a part of the screen has been studied. [0004] For example, there is...
