Abstract
A display apparatus includes a sight line detection unit that detects a line of sight of a user by analyzing user video information, an enhancement processing unit that detects an intersection point of the line of sight of the user detected by the sight line detection unit and a video display surface of a monitor as an attention point, which is a point on which the user focuses attention, and performs enhancement processing for the monitor by setting a higher gain amount in stages from a position of a longer distance from the attention point toward a position of a smaller distance, and a display video output control unit that outputs video via the monitor based on the gain amount set by the enhancement processing unit and display video information whose input is received by a display video information input unit.
Claims9
A display apparatus, comprising:
- a display video information input unit that receives input of display video information to be a source of video displayed in a monitor;
- a camera or cameras;
- a user video information input unit that receives input of user video information, which is acquired by the camera or cameras and video information of a user watching video displayed in the monitor;
- a sight line detection unit that detects a line of sight of the user by analyzing the user video information whose input is received by the user video information input unit;
- an enhancement processing unit that detects an intersection point of the line of sight of the user detected by the sight line detection unit and a video display surface of the monitor as an attention point and performs enhancement processing for the monitor by setting a higher gain amount in stages from a position of a longer distance from the attention point toward a position of a smaller distance;
- and
- a display video output control unit that outputs video via the monitor based on the gain amount set by the enhancement processing unit and the display video information whose input is received by the display video information input unit,
- said user video information input unit and said sight line detection unit being operable to detect a number of users currently watching the video displayed in the monitor, and when a detection result thereof indicates that more than one user is currently watching the video displayed in the monitor said enhancement processing unit obtains a respective attention point for each detected user and performs the enhancement processing with regard thereto to obtain a respective gain amount for said each detected user and superimposes gain amounts for all detected users by adding together each said respective gain amount to obtain a superimposed gain amount which is utilized in outputting the video via the monitor,
- wherein when the superimposed gain amount obtained by the enhancement processing unit exceeds a predetermined amount, the superimposed gain amount is reduced by subtracting a value therefrom or by multiplying by a value less than one.

A display method, comprising the steps of:
- receiving input of display video information to be a source of video displayed in a monitor through a display video information input unit;
- receiving input of user video information, which is acquired by a camera or cameras and video information of a user watching video displayed in the monitor through a user video information input unit;
- detecting a line of sight of the user by analyzing the user video information whose input is received by the user video information input unit through a sight line detection unit;
- detecting an intersection point of the line of sight of the user detected by the sight line detection unit and a video display surface of the monitor as an attention point and performing enhancement processing for the monitor by setting a higher gain amount in stages from a position of a longer distance from the attention point toward a position of a smaller distance through an enhancement processing unit;
- and
- outputting video via the monitor based on the gain amount set by the enhancement processing unit and the display video information whose input is received by the display video information input unit through a display video output control unit,
- and further comprising the steps of:
- detecting by use of said user video information input unit and said sight line detection unit a number of users currently watching the video displayed in the monitor, and when a detection result thereof indicates that more than one user is currently watching the video displayed in the monitor obtaining by use of said enhancement processing unit a respective attention point for each detected user and performing the enhancement processing with regard thereto to obtain a respective gain amount for said each detected user and superimposing gain amounts for all detected users by adding together each said respective gain amount to obtain a superimposed gain amount which is utilized in the outputting of the video via the monitor,
- wherein when the superimposed gain amount exceeds a predetermined amount, the superimposed gain amount is reduced by subtracting a value therefrom or by multiplying by a value less than one.
