Embodiment
In order to make those skilled in the art person understand better the present invention program, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is a kind of process flow diagram of regulating the method for display terminal picture disply parameter provided by the invention.
Referring to Fig. 1, a kind of method of regulating display terminal picture disply parameter provided by the invention may further comprise the steps:
Step S101: the change angle, location status and at least a picture disply parameter and the corresponding relation between them that set in advance display terminal;
Step S102: change angle or the location status of real-time detection display terminal;
Step S103: obtain the picture disply parameter corresponding with described change angle or location status;
Step S104: according to the picture disply parameter that obtains, the picture of described display terminal is adjusted.
In the present invention, described display terminal can comprise any devices with menu display function such as display and all-in-one.
In step S101, the location status of described display terminal can be set in advance according to user's needs, specifically can comprise the state of turning forward, the state that recedes, vertically laying state, left side heeling condition and the multiple location status such as side heeling condition to the right, certainly, also comprise other various location statuss.
In step S101, described picture disply parameter can be set in advance according to user's needs, the various picture disply parameters such as brightness, colourity, tone, contrast and form and aspect that specifically can comprise display terminal can also be other the parameter for the picture display effect of adjusting display terminal certainly.On the specific implementation, for example can be the parameter of gamma curve.
Need to prove, gamma curve is a kind of special tint ramp, being illustrated in image processes, relation between picture signal input value and the display device output brightness, when the parameter value of gamma curve equals 1, curve is the straight line at 45 ° with coordinate axis, represents that input and output density is identical this time, and the brightness of output picture does not change.Be higher than the brightening that 1 gamma curve parameter value will cause picture output, be lower than the darkening that 1 gamma curve parameter value can cause picture output.
In step S101, on the specific implementation, can set in advance the location status of multiple display terminal and one-one relationship or the many-one relationship between the multiple picture disply parameter.A kind of location status of display terminal can corresponding one or more picture disply parameters, for example, the display terminal state of turning forward can be corresponding with the value of three kinds of picture disply parameters such as the brightness of display terminal, colourity, tone, certainly, can also be the value of the picture disply parameter (such as the parameter of gamma curve) of other any kind.
On the specific implementation, for example, referring to Fig. 3, when the location status of described display terminal is vertical laying state (being standing state), the variation relation (being gamma curve) that display terminal of the present invention is inputted between the output brightness of the GTG signal value of different brightness and display terminal can for as shown in Figure 3, namely be adjusted the parameter value of gamma curve according to curve shown in Figure 3; In addition, when the location status of described display terminal when receding state, the variation relation (being gamma curve) that display terminal of the present invention is inputted between the output brightness of the GTG signal value of different brightness and display terminal can for as shown in Figure 4, namely be adjusted the parameter value of gamma curve according to curve shown in Figure 4.
In step S101, on the specific implementation, described picture disply parameter can be pre-set according to experimental data in process of production by display terminal manufacturer, need not the user and in use manually set.
In step S102 and S103, on the specific implementation, can come the current location status of real-time detection display terminal by gravity sensor, thereby obtain the picture disply parameter corresponding with described change angle or location status.
Need to prove, gravity sensor is that motion or gravity are converted to the sensor of electric signal, be mainly used in pitch angle, inertial force, impact and shake isoparametric measurement, can respond to the location status of self and whether the location status of the device installed changes.
For display terminals such as displays, on the specific implementation, the position movement that only has horizontal left and right directions and former and later two directions of level is effectively, and for example: lean forward, hypsokinesis and the limit, left side tilts, right edge tilts, at this time, the center of gravity of display terminal can change.And when moving up and down display terminal, because the center of gravity of display terminal can not change, can the picture of seeing not changed.Therefore, in the present invention, at the built-in accelerometer of gravity sensor, be divided into transverse axis (X-axis), Z-axis (Y-axis) gets final product, and the angle of these two axles just can detect the exercises of display terminal.Gravity sensor is placed on the display panel panel of display terminal, the mass of gravity sensor produces skew owing to being subject to gravity acceleration g component effect in an inclined direction, the output voltage of gravity sensor is changed, like this according to the variation of horizontal and vertical angle, gravity sensor can be exported a pair of voltage, obtain according to the angle difference a different set of to voltage, to distinguish different display terminal location statuss.According to different voltage ranges, automatically access corresponding display terminal location status.
In step S104, described display terminal can be adjusted the picture of this display terminal according to the picture disply parameter that obtains, to realize better visual effect (for example facing effect).
Need to prove that because people's range of vision is different, if do not stand in the optimal visibility angular range, the color of seeing and brightness will have error.Therefore, on specific implementation, the present invention can be according to the location status of display terminal, automatically adjust the picture disply parameter of display terminal, to gamma Gamma value and the contrast level parameter of display terminal, color, brightness, contrast etc. are carried out certain revisal, the decay such as the color of minimizing display terminal picture when side-looking and contrast, make its optimal visibility angle carry out " displacement ", reach the effect of positive apparent time, allow the user can see best visual state.
For example, when screen is looked up on the user inclined-plane, detection knows that the location status of display terminal is the state of receding, at this moment, by the default picture disply parameter of reading displayed terminal producer, can allow gamma Gamma value and the contrast level parameter of display terminal be adjusted, and allow and show that form and aspect, brightness and contrast also are compensated, thus can be so that the display effect of seeing be the same good when looking squarely.
Therefore, compared with prior art, for a kind of method of regulating display terminal picture disply parameter provided by the invention, it can be after the user adjusts the position of display terminal, location status by the detection display terminal, obtain corresponding picture disply parameter, then come the picture of display terminal is adjusted according to the picture disply parameter, thereby can allow the user normally see all the time the image content of display terminal, thereby can save the time of user's preciousness, work efficiency when the raising user uses display terminal strengthens the user to the product use impression of display terminal, is of great practical significance.
