The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in the form of software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.
In the present exemplary embodiment, first, an image display method is provided, which can be applied to an image receiving apparatus such as digital glasses; referring to fig. 1, the image display method may include the steps of:
s110, receiving a video source signal output by the image display through high-frequency out-of-phase superposition;
s120, after receiving a timing signal broadcasted by an image display, adjusting the phase of a stroboscopic switch of the digital glasses to be in phase with a first video source signal according to the timing signal;
s130, after the control button of the digital glasses is detected to be triggered, judging a corresponding control instruction according to analysis of the triggered condition of the control button;
and S140, after the control instruction is determined to be a video source switching instruction, adjusting the phase of a stroboscopic switch of the digital glasses to be in phase with a secondary video source signal so as to receive the secondary video source signal.
According to the image display method in the exemplary embodiment, on one hand, the digital glasses selectively view a plurality of video source signals played by the image display, so that the functions of the image display are expanded, and the hardware cost is reduced; on the other hand, the digital glasses realize the function that a plurality of people watch different video source signals simultaneously by switching the switching of the switching buttons, expand the application range of the image display, greatly improve the use effect and enhance the user experience.
Next, the image display method in the present exemplary embodiment will be further described.
In step S110, a video source signal output by the video display through high frequency out-of-phase superposition may be received;
in this exemplary embodiment, when the video source signals played by the video display are two or more, the two or more video source signals may be output by high-frequency out-of-phase superposition. Taking two video source signals as an example, a video source signal with a front superposition phase is defined as a primary video source signal, and a video source signal with a rear superposition phase is defined as a secondary video source signal, for example, a PAL video source signal is 25fps per second, that is, the refresh frequency of the image display is required to be at least 50Hz, and the primary video source signal and the secondary video source signal are alternately superposed at each 25fps per second, so that normal play and display of the two video source signals can be realized. The left and right glasses of the digital glasses receive video source signals sent by the image display in a visible light mode respectively.
In step S120, after receiving a timing signal broadcast by the image display, the strobe switch phase of the digital glasses may be adjusted to be in phase with the first video source signal according to the timing signal;
in this exemplary embodiment, the digital glasses are composed of glasses lenses including a liquid crystal layer having a voltage characteristic, the liquid crystal layer absorbs light when both ends are at a high level, the glasses lenses prevent the light from passing through, and the liquid crystal layer becomes transparent when both ends are at a low level, the glasses lenses allow the light to pass through. The general digital glasses use a strobe switch to change the voltage across the liquid crystal layer of the glasses lens to achieve the above-mentioned functions. By utilizing the voltage characteristic, the control of the two ends of the liquid crystal layer of the spectacle lens to be low level can be realized when the video display plays the first video source signal, the human eye can see the first video source signal, when the video display plays the second video source signal, the two ends of the liquid crystal layer of the spectacle lens are controlled to be high level, the human eye can not see the second video source signal and can see the black color of the spectacle lens, however, when the switching process is extremely fast, because of the persistence phenomenon caused by the afterglow effect of the human eye, the human vision still keeps images for a period of time, therefore, the human sees the images of the first video source signal all the time.
In order to enable the video display and the video source signals of the digital glasses to be switched in phase, the phenomenon that the liquid crystal layer of the digital glasses is switched when the same video source signal is not played is prevented, the video display needs to broadcast a timing signal, the general timing signal is a timestamp of the initial phase of the first video source signal, and the digital glasses receive the timing signal and then adjust the initial time of the stroboscopic switch phase of the digital glasses to be consistent with the timestamp of the initial phase of the first video source signal, so that the phenomenon can be avoided.
The mode of the video display broadcasting the timing signal can be one or more of communication modes such as infrared, Bluetooth or Wifi.
In addition, when the user used digital glasses at every turn, open digital glasses switch promptly after, the signal will according to the timing for the first time digital glasses's stroboscopic switch phase place adjustment is in phase with first video source signal, that is to say, open digital glasses monkey at the user at every turn, first received video source signal is first video source signal, it is follow-up, if the user has the video source to adjust the demand, then can switch on first video source signal basis, and then can be more orderly and more quick messenger's user adjusts to appointed video source signal, very big improvement user carries out the convenience that video source signal switched.
In step S130, after detecting that the control button of the digital glasses is triggered, determining a corresponding control instruction according to analysis of a triggered condition of the control button;
in this exemplary embodiment, the digital glasses include a control button, and the control button may generate a corresponding control instruction according to different triggered conditions, where the triggered conditions include the triggered times of the control button, the triggered duration of the control button, and the trigger torque of the control button when the control button is rotated; the control instructions include switching instructions, data instructions, and the like.
In this example embodiment, the triggered condition of the digital glasses control button may include the triggered times of the control button, the triggered times of the control button is detected according to the control instruction determined by analyzing the triggered condition of the control button, and the control instruction corresponding to the triggered times is found in a preset instruction correspondence table. Alternatively, the first and second electrodes may be,
the triggered condition of the digital glasses control button comprises triggered time length of the control button, a corresponding control instruction is judged according to analysis of the triggered condition of the control button, the triggered time length of the control button is detected, and the control instruction corresponding to the triggered time length is searched in a preset instruction corresponding table.
For example: the preset instruction correspondence table may be as shown in table 1:
| is triggered to | |
| Click | |
| 1 time | SELECT COMMAND-A/DETECT COMMAND "OK" |
| 2 times of continuous impact | SELECT COMMAND-B/DECISION COMMAND "ERROR" |
| Continuous impact for 3 times | Select instruction-C |
| Continuously hit for 4 times | Select instruction-D |
| Long hit | Switching video sources |

When the one-time pressing duration of the control button is more than 0.2ms and the inter-stroke time is more than 0.2ms, the control button is considered to be long-time pressed, and the defined control instruction is searched in a preset instruction corresponding table to be a video source switching instruction.
In this exemplary embodiment, the digital glasses communicate with the controller, and when it is detected that the control button of the digital glasses is triggered, the triggered condition of the control button is analyzed and determined as a data command, the digital command is sent to the controller.
In step S140, after determining that the control command is a video source switching command, the strobe switch phase of the digital glasses may be adjusted to be in phase with the secondary video source signal to receive the secondary video source signal.
In this example embodiment, after confirming that control command is video source switching command, change digital glasses ' stroboscopic switch phase place, will digital glasses ' stroboscopic switch phase place's initial time adjustment is unanimous with the time stamp of secondary video source signal initial phase place, at this moment, can realize when video display broadcast primary video source signal, control lens liquid crystal layer both ends are the high level, human eye can not see primary video source signal and what see is the black of lens, when video display broadcast secondary video source signal, control lens liquid crystal layer both ends are the low level, can see secondary video source signal.
