Embodiment
Can only adopt directionkeys such as upper and lower, left and right to realize focusing on to the remote controller in the conventional art; Inefficient operation; And very inconvenient problem the present invention proposes a kind of TV remote-control device, television set and on television screen, realizes the method for location fast.
Television set among the present invention is compared with conventional television; Distinctive points is: on television screen, be pasted with anti-infrared transparent film; The size of this anti-infrared transparent film can equate with the television screen size; Also can be bigger slightly than television screen size, but from cost consideration, optimum execution mode still is both equal and opposite in directions; This anti-infrared transparent film is the transparent membrane of on the part area, smearing anti-infrared ray medium, and the part that is not coated with anti-infrared medium is the part that has marked coordinate information; For example: certain video screen size is 720mm*576mm, then selects the size of film also to be 720mm*576mm, supposes with 5mm as positioning accuracy; Then being evenly distributed with 720/5=144 root X axis and 576/5=115 root Y axis on the film, in the present invention, is that X axis or Y axis all are to confirm with three coordinate figure; Wherein adding in front of three of coordinate less thaies, 0 supply; The mode that two axis circulate into line with three coordinate figure+spaces forms, like X=110, and Y=75; Represent the joint of the 110th X axis and the 75th Y axis, its expression mode is as shown in Figure 1; On film, equally distributed X axis, the Y axis, all the other areas are all coated anti-infrared ray medium, so, when infrared radiation is to anti-infrared transparent film, be not coated with that the coordinate information of anti-infrared medium is counter to be out.
The structure of the TV remote-control device among the present invention is as shown in Figure 2, and it comprises master chip (remote controller master chip), also comprises camera, memory, the image detection identification module of the band infrared filtering function that is connected with master chip;
The camera of said band infrared filtering function is used to gather the coordinate information that the anti-infrared transparent film on the television display screen reflects, and through being processed into picture, is transferred to the image detection identification module;
Said memory is used to store each point coordinate information pattern and the mapping relations table of coordinate information pattern and coordinate figure on the television display screen;
Said image detection identification module is used for the image that the camera with band infrared filtering function transmits and compares with the coordinate information pattern of memory, obtains the coordinate figure of correspondence on television display screen.
Utilize above-mentioned TV remote-control device that television set is realized the method for quick remote control location, may further comprise the steps:
1, the coordinate information pattern that in the memory of TV remote-control device, prestores; And the mapping relations table of coordinate information pattern and coordinate figure: this step at first need be sampled to the each point coordinate information on the television screen; Be example with the screen size of 720mm*576mm and the positioning accuracy of 5mm still, the 576/5=115 that the 720/5=144 of the X axis of need sampling opens pattern and Y axis opens pattern; Amounting to 259 patterns samples; After the sampling each pattern is carried out exclusive number, have only a numbering even each opens pattern, and number unique; Generally we take serial number, as: with first pattern numbering 001, second kind of numbering 002 ... The 259th pattern numbering 259; The mapping relations of setting up the concrete coordinate of each pattern and representative then form the mapping relations table; In memory, store each pattern, numbering and mapping relations table at last;
2, get into station-keeping mode: switch the remote control mode of operation; Remote control just can get into positioning states, and (these can be through software programming, and definition remote control button realizes that those skilled in the art are easy to realize; Here repeat no more), the camera of band infrared filtering function is started working;
3, scanning coordinate information imaging: the user is through the operating and remote controlling device; Facing to television screen; And to television screen transmission infrared ray; The camera of band infrared filtering function scans remote control dead ahead screen and the picture that scans is preserved imaging, because camera has been installed the infrared filtering device, so have only remote control coordinate information with anti-infrared transparent film production above the position can be scanned into picture;
4, obtain coordinate information: the image information that the camera of band infrared filtering function scans sends the image detection identification module in the TV remote-control device to; The image detection identification module calls the coordinate information pattern that prestores in the memory and compares; Obtain the pattern numbering; Search the corresponding coordinate figure of image information that scans, the i.e. coordinate figure of current focus on the television screen according to the mapping relations table;
5, screen coordinate location: remote control sends to television set with the coordinate figure of current focus on the television screen that gets access to; Television set shows current focus position through the icon form according to coordinate figure information on screen; This icon form class is similar to the mouse pointer form; Can be designed to arrow-shaped, I font, circular or the like;
Based on above step, the user just can utilize remote control that the application item on the television screen is focused on fast, located, and is very convenient, also strengthened interactivity.
