Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is a kind of structured flowchart of controlling the television set embodiment of viewing distance of the present invention;
Fig. 2 is a kind of structured flowchart of controlling television set second embodiment of viewing distance of the present invention.
Embodiment
As shown in Figure 1, be the schematic diagram of a kind of TV remote controller embodiment of the present invention.This remote controller 10 is except comprising conventional components such as shell, TV control button (not shown) and sender unit 13, also comprise video sensor component 11 and sampling unit 12, wherein the output of sampling unit 12 is connected to the input of sender unit 13.
Similar with normal remote control, the sender unit 13 in the present embodiment is installed in the front end of remote controller, and it can be infrared transmitting tube or Bluetooth transmission device etc.This sender unit 13 can send the triggering signal of TV operation button and the view data that sampling unit 12 produces simultaneously, when specific implementation, can distinguish above-mentioned two class signals by different id signals.
As shown in Figure 2, be a kind of schematic diagram that passes through the television set embodiment of cursor operations of the present invention.Similar with general television set, this television set comprises display screen and is used to receive the signal receiving device 24 of remote controller signal, this television set also comprises image extraction unit 23, cursor position computing unit 22 and cursor display unit 21 in addition, and wherein image extraction unit 23 is obtained view data from signal receiving device.
Image extraction unit 23 is used for extracting from the picture signal that signal receiving device 24 receives the display shape of display screen.Signal receiving device 24 is the image of video sensor component 11 picked-ups from the picture signal that remote controller 10 receives, and image extraction unit 23 is obtained the display shape data of display screen according to the analyses such as aberration of pixel in the image.Because the shape of television display screen is generally rectangle, and the color of display screen and frame or frame and television background wall, brightness etc. had tangible difference usually when it play TV programme, analysis such as aberration that therefore can be by image, brightness obtain in the view data display screen occupy the zone and then the display shape of acquisition display screen.
When specific implementation, only need frame or four summits of display screen of the display screen display shape that image extraction unit 23 obtains get final product.
Cursor position computing unit 22 is used for calculating the display position of cursor at display screen according to the display shape of display screen.According to the lens imaging principle, for the different object of distance, there are geometric deformation in object and actual object in the image that scioptics obtain.The object of equal length for example, apart from the nearer length of object in image of lens greater than distance lens object far away.Cursor position computing unit 22 promptly according to above-mentioned away from realization.
When specific implementation, cursor position computing unit 22 in the display shape of display screen on the length difference of the length difference of base and bottom and limit, left side and right edge determine the center position (cornerwise joining) of cursor during less than assign thresholds (this assign thresholds is according to the size of display screen and/or show) at display screen than regulating.
Cursor position computing unit 22 in the display shape of display screen on the base greater than the length difference on bottom and two bases during more than or equal to assign thresholds, determine cursor below the center position of display screen and cursor be directly proportional with the length difference on two bases apart from the distance of center position; This cursor position computing unit 22 in the display shape of display screen on the base less than the length difference on bottom and two bases during more than or equal to assign thresholds, determine cursor above the center position of display screen and cursor be directly proportional with the length difference on two bases apart from the distance of center position.
Cursor position computing unit 22 in the display shape of display screen the limit, left side greater than the length difference of right edge and dual-side during more than or equal to assign thresholds, determine cursor on the right side of the center position of display screen and cursor be directly proportional with the length difference of dual-side apart from the distance of center position; Cursor position computing unit 22 in the display shape of display screen right edge greater than the length difference of limit, left side and dual-side during more than or equal to assign thresholds, determine cursor in the left side of the center position of display screen and cursor be directly proportional with the length difference on both sides apart from the distance of center position.
Certainly, the cursor position computing unit also can be determined cursor position by other modes, for example by the angle of last bottom and the angle of left and right sides side etc.
Corresponding with the sender unit of remote controller 10, signal receiving device 24 can be infrared signal receiving apparatus or Bluetooth signal receiving system, and it is positioned on the panel at television display screen place.
In addition, in above-mentioned television set, also can comprise performance element, be used for selecting or carry out the action-item of cursor position according to the control signal that signal receiving device 24 receives.
In addition, cursor position computing unit 22 also can be realized in the following manner: determine the center position of cursor at display screen when being positioned at the center position (or the distance that departs from center position is less than assign thresholds) of image in the zone that the display shape of display screen is formed; Determine when the position of taking back in image, zone that the display shape of display screen is formed (or the distance that departs from center position is greater than assign thresholds) cursor on the right side of the center position of display screen and cursor be directly proportional with the distance of regional slip chart apart from the distance of center position as center position; Determine when the position that takes in image, zone that the display shape of display screen is formed (or the distance that departs from center position is greater than assign thresholds) cursor in the left side of the center position of display screen and cursor be directly proportional with the distance of described regional slip chart apart from the distance of center position as center position; Determine when position on the lower side in image, zone that the display shape of display screen is formed (or the distance that departs from center position is greater than assign thresholds) cursor above the center position of display screen and cursor be directly proportional with the distance of described regional slip chart apart from the distance of center position as center position; Determine when position on the upper side in image, zone that the display shape of display screen is formed (or the distance that departs from center position is greater than assign thresholds) cursor below the center position of display screen and cursor be directly proportional with the distance of described regional slip chart apart from the distance of center position as center position.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
