具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。另外，在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. In addition, if there is no conflict, the following embodiments and the features in the embodiments can be combined with each other.
目前，现有的小型显示设备，例如运动相机，较少采用双屏幕。部分具有双屏幕的显示设备因屏幕面积较小，则采用物理硬件或者虚拟按钮来进行切换。然而，上述屏幕切换方式无法适应于一些应用场景(例如极限运动)，导致用户体验较低。Currently, existing small display devices, such as sports cameras, rarely use dual screens. Some display devices with dual screens use physical hardware or virtual buttons to switch due to their small screen area. However, the above-mentioned screen switching method cannot be adapted to some application scenarios (such as extreme sports), resulting in a lower user experience.
为此，本发明实施例提供了一种屏幕显示切换方法，其发明构思在于，通过设置多种控制指令，方便显示设备在接收到控制指令后实现两个屏幕的切换，提高切换效率，以使显示设备适应于更多的应用场景。To this end, the embodiment of the present invention provides a screen display switching method. The inventive idea is to set a variety of control instructions to facilitate the display device to switch between the two screens after receiving the control instructions, thereby improving the switching efficiency so that The display device is adapted to more application scenarios.
图1是本发明实施例提供的一种屏幕显示切换方法的流程图，可以应用于设置有第一屏幕和第二屏幕的显示设备，其中显示设备可以为智能终端、平板电脑等电子设备，还可以为无人飞行器、汽车、遥控车、机器人、相机中的至少一种可移动平台。可理解的是，显示设备内还设置有处理器，该处理器可以执行一种屏幕显示切换方法，后续以处理器为执行主体描述各实施例。Figure 1 is a flowchart of a screen display switching method provided by an embodiment of the present invention, which can be applied to a display device provided with a first screen and a second screen, where the display device can be an electronic device such as a smart terminal, a tablet computer, etc. It can be at least one movable platform among unmanned aerial vehicles, automobiles, remote control vehicles, robots, and cameras. It is understandable that a processor is also provided in the display device, and the processor can execute a screen display switching method, and the following description of the embodiments is based on the processor.
可理解的是，第一屏幕和第二屏幕的位置可以是固定的，也可以是不 固定的。例如，第一屏幕和第二屏幕可以对应指定的屏幕，即对应关系固定，如第一屏幕是指显示设备正面的屏幕，第二屏幕是指显示设备背面的屏幕，即所述第一屏幕和所述第二屏幕分别位于所述显示设备的两个不同侧面。在显示设备包括多个屏幕时，该多个屏幕中的任何一个都有可能是第一屏幕或第二屏幕，即第一屏幕和第二屏幕可以对应当前显示的屏幕和需要切换到的屏幕，即对应关系不固定。It is understandable that the positions of the first screen and the second screen may be fixed or not. For example, the first screen and the second screen may correspond to designated screens, that is, the corresponding relationship is fixed. For example, the first screen refers to the screen on the front of the display device, and the second screen refers to the screen on the back of the display device, that is, the first screen and The second screens are respectively located on two different sides of the display device. When the display device includes multiple screens, any one of the multiple screens may be the first screen or the second screen, that is, the first screen and the second screen can correspond to the currently displayed screen and the screen to be switched to, That is, the corresponding relationship is not fixed.
参见图1，一种屏幕显示切换方法，包括：Referring to Figure 1, a screen display switching method includes:
在步骤101中，获取用户输入的控制指令。In step 101, a control instruction input by a user is acquired.
本实施例中，显示设备的处理器可以与显示设备中的传感器通信，其中传感器可以包括触摸屏、语音采集模组、摄像头中的一种或者多种。基于显示设备中的传感器，用户输入的控制指令的方式也可以包括以下至少一种：语音输入、操作切屏按键、预设手势操作。In this embodiment, the processor of the display device may communicate with sensors in the display device, where the sensors may include one or more of a touch screen, a voice collection module, and a camera. Based on the sensor in the display device, the manner of the control instruction input by the user may also include at least one of the following: voice input, operation of the screen cut button, and preset gesture operation.
在一示例中，在显示设备设置有语音采集模组时，用户可以对着语音采集模组进行语音输入，这样语音采集模组可以采集到用户的语音。为准确获取语音所表达的语义信息，语音设备内还预先设置有关键词，这样处理器获取用户输入的控制指令，参见图2，可以包括：处理器可以与语音采集模组通信连接，语音采集模组实时地或者周期性的采集语音数据，这样处理器可以获取到语音采集模组采集的语音数据(对应步骤201)。然后，处理器可以解析语音数据，得到文本数据(对应步骤202)。其中语音解析算法可以采用相关技术中的语音识别算法、语音分析算法等，例如梅尔频率倒谱系数(MFCC)，在能够获取到语音对应的文本数据的情况下，相应方案落入本申请的保护范围。之后，处理器可以检测文本数据内是否包括预先设置的关键字，若包括，则确定语音对应的关键字为用户输入的控制指令(对应步骤203)。其中，预先设置的关键字可以包括但不限于：切换屏幕、切屏、Screen Switch、Switch，或者本屏看不到。这些关键字可以以表格或者数据库的形式存储在显示设备本地，以方便处理器读取。In an example, when the display device is provided with a voice collection module, the user can input voice to the voice collection module, so that the voice collection module can collect the user's voice. In order to accurately obtain the semantic information expressed by the voice, keywords are also preset in the voice device, so that the processor obtains the control instructions input by the user. See Figure 2, which may include: the processor can communicate with the voice collection module, and the voice collection The module collects voice data in real time or periodically, so that the processor can obtain the voice data collected by the voice collection module (corresponding to step 201). Then, the processor can parse the voice data to obtain text data (corresponding to step 202). Among them, the speech analysis algorithm can use speech recognition algorithms and speech analysis algorithms in related technologies, such as Mel Frequency Cepstral Coefficient (MFCC). When the text data corresponding to the speech can be obtained, the corresponding solution falls into the scope of this application. protected range. After that, the processor can detect whether the text data includes a preset keyword, and if it includes, it determines that the keyword corresponding to the voice is a control instruction input by the user (corresponding to step 203). Among them, the preset keywords may include, but are not limited to: switch screen, switch screen, screen switch, switch, or invisible on this screen. These keywords can be stored locally in the display device in the form of a table or database to facilitate the processor to read.
本实施例中通过语音输入控制指令，这样用户的活动范围可以大大增加即不会限制用户的使用位置，有利于扩展显示设备的应用场景。In this embodiment, the control instruction is input by voice, so that the user's activity range can be greatly increased, that is, the user's use position is not restricted, which is beneficial to expand the application scenarios of the display device.
在另一示例中，在显示设备设置有触摸屏，即第一屏幕和/或第二屏幕为触摸屏时，用户可以以对着触摸屏进行操作。在一场景中，触摸屏包括切屏按键，这样处理器获取用户输入的控制指令，参见图3，包括：处理器可以与第一屏幕和第二屏幕通信连接，从而可以监控到切屏按键(对应步骤301)。若监控到用户操作切屏按键且满足预先设置的操作条件，则确定获取到用户输入的控制指令(对应步骤302)。预先设置的操作条件可以包括但不限于：切屏按键被按下时间超过预设时长、被连续点击多次。本示例中通过设置切屏按键，可以方便用户直接操作切屏按键，提高切屏效率。In another example, when the display device is provided with a touch screen, that is, when the first screen and/or the second screen are touch screens, the user can operate on the touch screen. In one scenario, the touch screen includes a screen cut button, so that the processor obtains the control instruction input by the user, as shown in Figure 3, including: the processor can communicate with the first screen and the second screen, so that the screen cut button (corresponding to Step 301). If it is monitored that the user operates the screen cut button and the preset operating condition is met, it is determined that the control instruction input by the user is acquired (corresponding to step 302). The preset operating conditions may include, but are not limited to: the screen-cutting button has been pressed for more than a preset time period, and has been continuously clicked multiple times. In this example, by setting the screen cutting button, it is convenient for the user to directly operate the screen cutting button and improve the screen cutting efficiency.
在另一场景中，用户可以对触摸屏进行手势操作，可以包括点击、滑动、双指拖动、双指双击、双指滑动、单击双击、三指滑动等手势操作，技术人员可以根据具体场景设置手势操作，在能够使显示设备获得到用户控制指令的情况下，相应手势操作落入本申请的保护范围。可理解的是，本示例中显示设备内还可以设置预设手势，将预设手势作为控制指令，可以包括以下至少一种：双指双击、双指滑动、单击双击、三指滑动。当然，技术人员还可以根据具体场景设备预设手势，在能够作为控制指令的情况下，相应方案落入本申请的保护范围。这样，处理器获取用户输入的控制指令，参见图4，可以包括：处理器可以分别与第一屏幕和第二屏幕通信连接，第一屏幕和第二屏幕可以为触摸屏，且可以检测用户针对第一屏幕和/或第二屏幕的触摸操作。以触摸操作第一屏幕为例，处理器可以监控第一屏幕的触摸操作(对应步骤401)。然后。处理器判断触摸操作内是否包括预设手势，若包括预设手势，则处理器确定获取到用户输入的控制指令(对应步骤402)。本示例中通过设置预设手势，方便用户使用自身熟悉的手势实现切换，提高切屏效率和使用体验。In another scenario, the user can perform gesture operations on the touch screen, including tap, slide, two-finger drag, two-finger double-tap, two-finger slide, double-click, three-finger slide and other gesture operations. Setting the gesture operation, in the case that the display device can obtain the user control instruction, the corresponding gesture operation falls into the protection scope of this application. It is understandable that, in this example, a preset gesture may also be set in the display device, and the preset gesture may be used as a control instruction, which may include at least one of the following: two-finger double-tap, two-finger sliding, single-tap double-tap, and three-finger sliding. Of course, technicians can also preset gestures according to specific scenes, and if they can be used as control instructions, the corresponding solutions fall within the protection scope of this application. In this way, the processor obtains the control instruction input by the user, referring to FIG. 4, which may include: the processor may be communicatively connected to the first screen and the second screen, respectively, the first screen and the second screen may be touch screens, and can detect that the user is directed to the first screen Touch operation on one screen and/or second screen. Taking the touch operation of the first screen as an example, the processor may monitor the touch operation of the first screen (corresponding to step 401). then. The processor determines whether the preset gesture is included in the touch operation, and if the preset gesture is included, the processor determines that the control instruction input by the user is acquired (corresponding to step 402). In this example, by setting preset gestures, it is convenient for users to use their familiar gestures to switch, which improves screen cutting efficiency and user experience.
在一示例中，以预设手势为双指双击为例，处理器判断触摸操作内是 否包括预设手势，参见图5，包括：处理器通过与触摸屏通信，可以检测到用户手指是否已经按下。若检测到用户有手指按下，处理器记录各手指的当前触摸时间；手指包括第一手指和第二手指(对应步骤501)。其中第一手指和第二手指并非特定的手指，而是先按下的手指为第一手指，后按下的手指为第二手指。然后，处理器检测第一手指和所述第二手指是否抬起，根据检测结果确定是否检测到双指双击事件(对应步骤502)。In one example, taking the preset gesture as a two-finger double-tap as an example, the processor determines whether the preset gesture is included in the touch operation, as shown in Figure 5, including: the processor can detect whether the user's finger has been pressed by communicating with the touch screen . If it is detected that the user has pressed a finger, the processor records the current touch time of each finger; the fingers include the first finger and the second finger (corresponding to step 501). The first finger and the second finger are not specific fingers, but the first finger is the first finger, and the second finger is the second finger. Then, the processor detects whether the first finger and the second finger are lifted, and determines whether a two-finger double-tap event is detected according to the detection result (corresponding to step 502).
本示例中，处理器根据检测结果确定是否检测到双指双击事件，参见图6，包括：针对第二手指，若检测到第二手指抬起，则处理器基于第二手指抬起对应的当前时间、第二手指的最后一次释放时间和设定时长调整双指双击释放次数(对应步骤601)。例如，参见图7，处理器判断第二手指抬起对应的当前时间与第二手指的最后一次释放时间之差是否超过设定时长(对应步骤701)。若超过设定时长，则将双指双击释放次数调整为第一状态；若否，则维持所述双指双击释放次数的当前状态(对应步骤702)。其中设定时长可以根据具体场景进行设置，例如500ms～1000ms。然后，基于第二手指的偏移量和设定阈值调整双指双击释放次数，以及第二手指的释放时间(对应步骤602)。例如，参见图8，处理器可以判断第二手指抬起位置和按下位置之间的偏移量，并判断偏移量是否超过设定阈值(对应步骤801)。若偏移量超过设定阈值，则将双指双击释放次数调整为第二状态；若偏移量小于设定阈值，则将双指双击释放次数调整为当前状态的下一状态(对应步骤802)。可理解的是，考虑到预设手势为双指双击，因此双指双击释放次数可以包括第一状态(即次数为0)、第二状态(即次数为1)和第三状态(即次数为2)。In this example, the processor determines whether a two-finger double-tap event is detected according to the detection result, see Figure 6, including: for the second finger, if the second finger is detected to be lifted, the processor is based on the second finger lifted corresponding current Time, the last release time of the second finger and the set duration adjust the number of double-finger releases (corresponding to step 601). For example, referring to FIG. 7, the processor determines whether the difference between the current time corresponding to the second finger lifting and the last release time of the second finger exceeds the set time period (corresponding to step 701). If it exceeds the set time period, adjust the two-finger double-click release times to the first state; if not, maintain the current state of the two-finger double-click release times (corresponding to step 702). The setting duration can be set according to specific scenarios, for example, 500ms～1000ms. Then, the number of two-finger double-tap releases and the release time of the second finger are adjusted based on the offset of the second finger and the set threshold (corresponding to step 602). For example, referring to FIG. 8, the processor may determine the offset between the raised position and the pressed position of the second finger, and determine whether the offset exceeds a set threshold (corresponding to step 801). If the offset exceeds the set threshold, adjust the number of two-finger double-click releases to the second state; if the offset is less than the set threshold, adjust the number of two-finger double-click releases to the next state of the current state (corresponding to step 802 ). It is understandable that, considering that the preset gesture is a two-finger double-tap, the number of two-finger double-tap releases can include the first state (that is, the number of times is 0), the second state (that is, the number of times is 1), and the third state (that is, the number of times is 1). 2).
本示例中，处理器根据检测结果确定是否检测到双指双击事件，参见图9，包括：针对所述第一手指，若检测到第一手指抬起，则处理器记录第一手指的抬起位置和按下位置的偏移坐标，以及调整单指双击释放次数(对应步骤901)。参见图10，处理器调整单指双击释放次数包括：In this example, the processor determines whether a two-finger double-tap event is detected according to the detection result, see FIG. 9, including: for the first finger, if the first finger is detected to be lifted, the processor records the lift of the first finger The offset coordinates of the position and the pressed position, and the adjustment of the single-finger double-click release times (corresponding to step 901). Referring to Figure 10, the processor adjusts the single-finger double-click release times including:
判断所述第一手指抬起对应的当前时间与第一手指的最后一次释放时 间之差是否大于设定时长(对应步骤1001)。设定时长可以根据具体场景进行设置，例如500ms～1000ms。若大于设定时长，处理器将单指双击释放次数调整为第二状态；若否，则将单指双击释放次数调整为当前状态的下一状态(对应步骤1002)。It is determined whether the difference between the current time corresponding to the lifting of the first finger and the last release time of the first finger is greater than the set duration (corresponding to step 1001). The setting duration can be set according to specific scenarios, for example, 500ms～1000ms. If it is longer than the set duration, the processor adjusts the single-finger double-click release times to the second state; if not, adjusts the single-finger double-click release times to the next state of the current state (corresponding to step 1002).
之后，处理器可以确定单指双击释放次数的当前状态(对应步骤902)。若单指双击释放次数为第二状态，则基于第一手指的偏移量和设定阈值调整单指双击释放次数的状态(对应步骤903)。After that, the processor can determine the current state of the single-finger double-click release times (corresponding to step 902). If the number of single-finger double-click releases is in the second state, the status of the single-finger double-click release number is adjusted based on the offset of the first finger and the set threshold (corresponding to step 903).
其中，处理器基于第一手指的偏移量和设定阈值调整单指双击释放次数的状态，参见图11，可以包括：处理器可以确定第一手指的偏移量是否超过设定阈值(对应步骤1101)。若是，处理器将双指双击释放次数调整为第一状态；若否，处理器维持双指双击释放次数的当前状态(对应步骤1102)。Wherein, the processor adjusts the state of the number of single-finger double tap releases based on the offset of the first finger and the set threshold. See FIG. 11, which may include: the processor may determine whether the offset of the first finger exceeds the set threshold (corresponding to Step 1101). If yes, the processor adjusts the two-finger double-click release times to the first state; if not, the processor maintains the current state of the two-finger double-click release times (corresponding to step 1102).
需要说明的是，处理器在确定单指双击释放次数的当前状态之后，若单指双击释放次数为第三状态，则判断第一手指的当前位置是否在前一次点击位置的设定范围内；若位于前一次点击位置的设定范围内，则确定检测到单指双击事件。其中，设定范围可以根据具体场景进行调整，例如可以为120像素*120像素的矩形区域。It should be noted that after determining the current state of the single-finger double-click release times, the processor determines whether the current position of the first finger is within the set range of the previous click position if the single-finger double-click release times is the third state; If it is within the set range of the previous click position, it is determined that a single-finger double-click event is detected. Among them, the setting range can be adjusted according to a specific scene, for example, it can be a rectangular area of 120 pixels*120 pixels.
本示例中，处理器基于第一手指上次释放时间和第二手指的触摸时间调整双指双击释放次数的状态，并记录所述第一手指的释放时间(对应步骤904)。之后，处理器判断双指双击释放次数的当前状态，若双指双击释放次数为第三状态，则确定检测到双指双击事件(对应步骤905)。In this example, the processor adjusts the state of the number of double-finger double-tap release times based on the last release time of the first finger and the touch time of the second finger, and records the release time of the first finger (corresponding to step 904). After that, the processor judges the current state of the two-finger double-click release times, and if the two-finger double-click release times is the third state, it determines that the two-finger double-click event is detected (corresponding to step 905).
其中，处理器基于第一手指上次释放时间和第二手指的触摸时间调整双指双击释放次数的状态，参见图12，可以包括：处理器判断第一手指上次释放时间是否大于第二手指的触摸时间(对应步骤1201)。若是，则将双指双击释放次数调整为当前状态的下一状态；若否，则维持所述双指双击释放次数的当前状态(对应步骤1202)。Wherein, the processor adjusts the state of the two-finger double-tap release times based on the last release time of the first finger and the touch time of the second finger. See FIG. 12, which may include: the processor determines whether the last release time of the first finger is greater than that of the second finger Touch time (corresponding to step 1201). If yes, adjust the two-finger double-click release times to the next state of the current state; if not, maintain the current state of the two-finger double-click release times (corresponding to step 1202).
最后，处理器判断双指双击释放次数是否为第三状态，若双指双击释 放次数为第三状态，则确定检测到双指双击事件(对应步骤603)。Finally, the processor determines whether the two-finger double-click release times are in the third state, and if the two-finger double-click release times are in the third state, it determines that a two-finger double-click event is detected (corresponding to step 603).
上述各实施例中以显示设备上设置有触摸屏为例描述了双指双击操作的内容。可理解的是，在显示设备上设置有摄像头时，若用户伸双指在空中来回摆2次，该摄像头可以采集到用户手部图像或者视频，并分析出用户的手势，同样可以确定用户手势为双指双击手势。其中手势分析可以采用相关技术中的目标跟踪算法实现，具体方案可以参考相关技术中，在此不再表述。In the foregoing embodiments, a touch screen is provided on the display device as an example to describe the content of the two-finger double-click operation. It is understandable that when a camera is provided on the display device, if the user swings two fingers back and forth in the air twice, the camera can collect an image or video of the user's hand, and analyze the user's gesture, which can also determine the user's gesture It is a two-finger double-tap gesture. The gesture analysis can be implemented by using the target tracking algorithm in the related technology, and the specific solution can be referred to in the related technology, which will not be described here.
在步骤102中，若所述控制指令为切屏指令，则将输入到所述第一屏幕的数据码流切换到所述第二屏幕，所述第二屏幕显示所述数据码流对应的图像。In step 102, if the control instruction is a screen cut instruction, the data code stream input to the first screen is switched to the second screen, and the second screen displays the image corresponding to the data code stream .
本实施例中，处理器在确定控制指令为切屏指令后可以生成切屏消息发送给切屏模块。切屏模块基于切屏消息停止当前屏幕即第一屏幕Liveview(一种图形化工具)/OSD(On-Screen Display，屏幕菜单式调节方式)，即停止向当前屏幕输入数据码流。处理器将数据码流切换到另一屏幕即第二屏幕。重新启动Liveview/OSD后，由第二屏幕显示对应的图像，完成屏幕切换。In this embodiment, the processor may generate a screen cutting message and send it to the screen cutting module after determining that the control instruction is a screen cutting instruction. The screen cutting module stops the current screen, which is the first screen Liveview (a graphical tool)/OSD (On-Screen Display, screen menu adjustment method) based on the screen cutting message, that is, stops inputting the data stream to the current screen. The processor switches the data stream to another screen, the second screen. After restarting Liveview/OSD, the corresponding image will be displayed on the second screen to complete the screen switching.
至此，本实施例中通过获取用户输入的控制指令，从而可以在控制指令为切屏指令时，则将输入到所述第一屏幕的数据码流切换到所述第二屏幕，第二屏幕显示所述数据码流对应的图像。这样，本实施例中用户输入的控制指令可以包括多种，并不局限于现有的物理硬件或者虚拟按钮，可以保证在尽可能多的应用场景下，尤其是极限运动场景下实现屏幕显示切换，达到快速切换屏幕的效果，有利于提升用户的使用体验。So far, in this embodiment, by acquiring the control instruction input by the user, when the control instruction is a screen cutting instruction, the data stream input to the first screen can be switched to the second screen, and the second screen displays The image corresponding to the data stream. In this way, the control commands input by the user in this embodiment can include multiple types, and are not limited to existing physical hardware or virtual buttons, and can ensure that screen display switching can be achieved in as many application scenarios as possible, especially in extreme sports scenarios. , To achieve the effect of quickly switching screens, which is conducive to improving the user experience.
下面以不同输入场景下为例描述一种屏幕显示切换方法，参见图13和图14：The following describes a screen display switching method under different input scenarios as an example, see Figure 13 and Figure 14:
如图13所示，在按键切屏的场景中，当用户按下切屏按键后，该切屏按键可以为物理按钮或者虚拟按钮，并开始计时T。当用户抬起切屏按键后，停止计算计时T并判断T是否大于(包括等于)设定时长500ms。若 T小于500ms，则重新检测切屏按键是否被按下，若T大于500ms，则确定需要进行屏幕切换生成切屏消息，发送给切屏模块。切屏模块停止向当前屏幕的数据码流，即当前屏幕停止Liveview/OSD。将数据码流切换到另一屏幕，重新启动Liveview/OSD，由另一屏幕显示相应内容，从而完成切屏操作。As shown in FIG. 13, in the scene where the user presses the screen cut button, the screen cut button can be a physical button or a virtual button, and the timer T starts. When the user lifts the screen-cutting button, the counting of timer T is stopped and it is judged whether T is greater than (including equal to) the set duration of 500ms. If T is less than 500ms, check whether the screen cutting button is pressed again. If T is greater than 500ms, it is determined that screen switching is required to generate a screen cutting message and send it to the screen cutting module. The screen cut module stops the data stream to the current screen, that is, the current screen stops Liveview/OSD. Switch the data stream to another screen, restart Liveview/OSD, and display the corresponding content on another screen to complete the screen cut operation.
继续如图13所示，在语音切屏的场景中，当采集语音数据，对语音数据进行文本分析并识别出文本数据内的关键词，若关键词不是预设关键词，则重新采集语音数据，若是预设关键词，则确定需要进行屏幕切换生成切屏消息，发送给切屏模块。切屏模块停止向当前屏幕的数据码流，即当前屏幕停止Liveview/OSD。将数据码流切换到另一屏幕，重新启动Liveview/OSD，由另一屏幕显示相应内容，从而完成切屏操作。Continue as shown in Figure 13, in the scene of voice cut screen, when the voice data is collected, the voice data is text analyzed and the keywords in the text data are recognized. If the keywords are not preset keywords, the voice data is collected again If it is a preset keyword, it is determined that screen switching is required to generate a screen cutting message and send it to the screen cutting module. The screen cut module stops the data stream to the current screen, that is, the current screen stops Liveview/OSD. Switch the data stream to another screen, restart Liveview/OSD, and display the corresponding content on another screen to complete the screen cut operation.
如图14所示，在双指双击切屏的场景中，检测用户是否按下手指0(即第一手指)和手指1(即第二手指)，若按下手指0则记录当前触摸时间LastTouchT，若按下手指1则记录当前触摸时间DoubleLastTouchT。然后，判断手指0和手指1是否定义在热区(即设定范围，例如屏幕的显示区域的四个角落)内，若不在热区内，则重新检测手指0。需要说明的是，当手指0和手指1全部位于热区外，则重新检测两者是否被按下；若有一个位于热区外，则未超出热区外的手指变成手指1，另一个手指变为手指0并重新检测。As shown in Figure 14, in the scene of two-finger double-tap to cut the screen, it is detected whether the user presses finger 0 (ie the first finger) and finger 1 (ie the second finger). If finger 0 is pressed, the current touch time LastTouchT is recorded , If finger 1 is pressed, the current touch time DoubleLastTouchT will be recorded. Then, it is judged whether finger 0 and finger 1 are defined in the hot zone (that is, the setting range, for example, the four corners of the display area of the screen). If they are not in the hot zone, finger 0 is detected again. It should be noted that when finger 0 and finger 1 are all outside the hot zone, re-check whether they are pressed; if one is outside the hot zone, the finger that does not exceed the hot zone becomes finger 1, and the other The finger becomes finger 0 and re-detects.
若手指0和手指1全部位于热区内，则包括：If finger 0 and finger 1 are all in the hot zone, it includes:
针对手指0 Target finger 0
若检测到用户抬起手指0，则记录手指0抬起位置和点击位置的偏移x坐标和y坐标，即dx和dy。然后，计算当前时刻与当前触摸时间LastTouchT之差是否超过500ms，若超过则将单指双击释放次数ReleaseCnt清零后加1(即调整为第二状态)，若小于将单指双击释放次数ReleaseCnt加1(调整为当前状态的下一状态)。If it is detected that the user lifts finger 0, the offset x coordinate and y coordinate of the lifted position and the clicked position of the finger 0 are recorded, namely dx and dy. Then, calculate whether the difference between the current time and the current touch time LastTouchT exceeds 500ms. If it exceeds, the single-finger double-click release times ReleaseCnt is cleared and added to 1 (that is, adjusted to the second state), if it is less than the single-finger double-click release times ReleaseCnt is added 1 (adjust to the next state of the current state).
若单指双击释放次数ReleaseCnt为第二状态，则记录当前点击位置的 x坐标TouchHitXLast和y坐标TouchHitYLast。若单指双击释放次数ReleaseCnt为第三状态，则确定当前位置是否在上位点击位置的120*120范围内，若是确定检测到单指双击事件，若否，则转换到下一步。If the release number of single-finger double-click ReleaseCnt is in the second state, the x coordinate TouchHitXLast and the y coordinate TouchHitYLast of the current click position are recorded. If the single-finger double-click release times ReleaseCnt is in the third state, it is determined whether the current position is within the range of 120*120 of the upper click position, if it is determined that a single-finger double-click event has been detected, if not, then transition to the next step.
判断偏移量dx和dy是否超过设定范围120*120，若是则将双指双击释放次数ReleaseTouchCnt清零(即调整为第一状态)，若否，则转换到下一步。Determine whether the offsets dx and dy exceed the setting range of 120*120, if so, clear the number of releases of the two-finger double-click ReleaseTouchCnt to zero (ie, adjust to the first state), if not, switch to the next step.
手指0上次释放时间是否大于手指1的触摸时间，若是，则双指双击释放次数ReleaseTouchCnt加1，并记录手指0释放时间LastReleaseT，若否则记录手指0释放时间LastReleaseT。Whether the last release time of finger 0 is greater than the touch time of finger 1, if yes, the release time of two-finger double-click ReleaseTouchCnt is increased by 1, and the release time of finger 0 LastReleaseT is recorded, if not, the release time of finger 0 LastReleaseT is recorded.
针对手指1 Target finger 1
若检测到用户抬起手指1，则计算当前时刻与当前触摸时间DoubleLastTouchT之差是否超过500ms，若超过则将双指双击释放次数ReleaseTouchCnt清零(即调整为第一状态)并判断偏移量dx/dy是否超过设定范围120*120；若小于判断偏移量dx/dy是否超过设定范围120*120。If it is detected that the user lifts the finger 1, calculate whether the difference between the current time and the current touch time DoubleLastTouchT exceeds 500ms, if it exceeds, clear the number of double-finger double-click releases ReleaseTouchCnt to zero (ie adjust to the first state) and determine the offset dx Whether /dy exceeds the setting range of 120*120; if it is smaller, judge whether the offset dx/dy exceeds the setting range of 120*120.
判断偏移量dx和dy是否超过设定范围120*120，若是则将双指双击释放次数ReleaseTouchCnt清零(即调整为第一状态)，若否，则转换到下一步。Determine whether the offsets dx and dy exceed the setting range of 120*120, if so, clear the number of releases of the two-finger double-click ReleaseTouchCnt to zero (ie, adjust to the first state), if not, switch to the next step.
将双指双击释放次数ReleaseTouchCnt加1，并记录手指1释放时间DoubleLastReleaseT。Add 1 to the release times of the two-finger double-click ReleaseTouchCnt, and record the release time DoubleLastReleaseT of finger 1.
然后判断手指0上次释放时间是否大于手指1的触摸时间，若是检测到双指双击事件，即确定出需要进行屏幕切换生成切屏消息，发送给切屏模块。切屏模块停止向当前屏幕的数据码流，即当前屏幕停止Liveview/OSD。将数据码流切换到另一屏幕，重新启动Liveview/OSD，由另一屏幕显示相应内容，从而完成切屏操作。Then it is judged whether the last release time of finger 0 is greater than the touch time of finger 1. If a double-finger double-tap event is detected, it is determined that a screen switch is required to generate a screen cut message, which is sent to the screen cut module. The screen cut module stops the data stream to the current screen, that is, the current screen stops Liveview/OSD. Switch the data stream to another screen, restart Liveview/OSD, and display the corresponding content on another screen to complete the screen cut operation.
