Fig. 1 is a kind of structural representation of automatically adjusting the television set of resolution according to viewing distance provided by the invention
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
At first need to prove, resolution of the present invention all comprises horizontal resolution and vertical resolution, be that image resolution ratio comprises the horizontal resolution of image and the vertical resolution of image, the resolution of television set comprises the horizontal resolution of television set and the vertical resolution of television set.
Referring to Fig. 1, a kind of television set of automatically adjusting resolution according to viewing distance comprise picture signal receive module, apart from detection module, picture signal processing module.
Picture signal receives module, is used for receiving the picture signal of the outside input of television set, and the picture signal that receives is sent to the picture signal processing module;
Apart from detection module, for detection of the viewing distance between user and the television set, and the viewing distance that detects sent to the picture signal processing module;
The picture signal processing module be used for to receive picture signal and receives the picture signal that module sends over and the viewing distance that sends over apart from detection module, and the viewing distance that receives and set distance threshold are compared.Maximum horizontal resolution and maximum perpendicular resolution that the horizontal resolution that has according to picture signal again and vertical resolution and television set are supported, picture signal is processed, adjust the resolution of picture signal, then show the picture signal of adjusted resolution at television screen.
Below main explanation how adjust the resolution of picture signal according to viewing distance:
The picture signal processing module is provided with distance threshold, and for avoiding frequent adjustment, set distance threshold can be two: x, y (x＜y), also can more distance threshold be set according to actual conditions herein.
The people who detects when the distance detection module and the viewing distance between the TV are less than distance threshold x the time; then the resolution of picture signal is not adjusted; directly demonstrate picture signal by video screen; in addition; the prompt text that can also show at video screen " vision protection woulds you please note viewing distance ".
If the viewing distance that detects apart from detection module is between x and y, when being x≤viewing distance≤y, then the horizontal resolution of picture signal and the vertical resolution of picture signal be multiply by respectively predefined constant a, obtain the new horizontal resolution of image and new vertical resolution; If the distance value that detects apart from detection module then multiply by respectively predefined constant b with the horizontal resolution of picture signal and the vertical resolution of picture signal greater than distance threshold y, obtain the new horizontal resolution of image and new vertical resolution.
The horizontal resolution of picture signal and vertical resolution multiply by respectively after predefined constant a or the constant b, if the horizontal resolution that picture signal is new and new vertical resolution be respectively less than the horizontal resolution of TV and the vertical resolution of TV, the resolution that shows at television screen of picture signal is the new horizontal resolution of image and new vertical resolution so.Such as, the ultimate resolution of television set support is 1366 * 768, and the resolution of the image after the adjustment resolution is 720 * 576, and image is 720 * 576 in the resolution that television set shows so.
The horizontal resolution of picture signal and vertical resolution multiply by respectively after predefined constant a or the constant b, if the horizontal resolution that the horizontal resolution that picture signal is new is supported greater than TV, and the vertical resolution that new vertical resolution is supported less than TV, the horizontal resolution that the key diagram image signal is new has exceeded the maximum horizontal resolution that television set is supported, needs again the resolution of picture signal to be adjusted.Calculate the new vertical resolution of picture signal according to formula (the original new original vertical resolution of vertical resolution/picture signal of horizontal resolution=picture signal of maximum horizontal resolution/picture signal that television set is supported) so, the horizontal resolution that picture signal is new equals the maximum horizontal resolution that television set is supported.
The horizontal resolution of picture signal and vertical resolution multiply by respectively after predefined constant a or the constant b, if the vertical resolution that the vertical resolution that picture signal is new is supported greater than TV, and the horizontal resolution that new horizontal resolution is supported less than TV, the vertical resolution that the key diagram image signal is new has exceeded the maximum perpendicular resolution that television set is supported, needs again the resolution of picture signal to be adjusted.Calculate the new horizontal resolution of picture signal according to formula (the original new original horizontal resolution of horizontal resolution/picture signal of vertical resolution=picture signal of maximum perpendicular resolution/picture signal that television set is supported) so, the vertical resolution that picture signal is new equals the maximum perpendicular resolution that television set is supported.
The horizontal resolution of picture signal and vertical resolution multiply by respectively after predefined constant a or the constant b, if new horizontal resolution and new vertical resolution are respectively greater than the horizontal resolution of TV and the vertical resolution of TV, new horizontal resolution and new vertical resolution that the image that obtains is described have exceeded the ultimate resolution that TV is supported, the resolution that shows at television screen of picture signal is the ultimate resolution that television set is supported so.Such as, the ultimate resolution of television set support is 1366 * 768, and the resolution of the image after the adjustment resolution is 1920 * 1080, and image is 1366 * 768 in the resolution that television set shows so.
Should be noted that aspect the setting of distance threshold and constant, can adjust according to actual conditions.Such as can setting more distance threshold, interval at different distance thresholds, when image resolution ratio was adjusted, the constant of taking advantage of also can rule of thumb be worth and carries out value.
Should be noted that when image signal resolution is adjusted the horizontal resolution of image and the vertical resolution of image multiply by respectively same constant, is in order to allow as far as possible picture signal the phenomenon of ratio distortion not occur in convergent-divergent.
On the concrete practice, when if television set need to be adjusted the resolution of picture signal, can eject selection information at television screen, whether the inquiry user needs to adjust the resolution of picture signal, and prompting is adjusted and picture signal may be occurred after the resolution and a little distortion phenomenon occurs, if user's selection is negated, the resolution of picture signal is not adjusted so, if user's selection is sure, show at video screen again after then the resolution of picture signal being adjusted.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
