本发明涉及一种影像的显示方法及其显示设备，特别是涉及一种预防讯号切换导致画面显示异常的显示方法及其显示设备。The present invention relates to an image display method and its display device, in particular to a display method and its display device for preventing abnormal picture display caused by signal switching.
背景技术Background technique
由于3D技术日臻成熟，因此相关产品也渐渐地出现在人们的日常生活当中，例如可输出3D影像的显示器。一般而言，上述的显示器采用版本为「1.4」的高清晰度多媒体接口（HighDefinitionMultimediaInterface，HDMI）接收来源讯号、画面与数字资料，例如720p讯号或1080p讯号，2D画面或3D画面。其中3D画面若以像素(Pixel)的排列方式进一步区分，主要可以分为三种态样，其分别是影像框封装(FramePacking)、影像左右并排(SidebySide)、影像上下并排(TopandBottom)等等。而数字资料代表的即是画面的排列态样。As 3D technology is becoming more and more mature, related products are gradually appearing in people's daily life, such as monitors capable of outputting 3D images. Generally speaking, the above-mentioned displays use the version "1.4" High Definition Multimedia Interface (HDMI) to receive source signals, images and digital data, such as 720p signals or 1080p signals, 2D images or 3D images. Among them, if the 3D screen is further distinguished by the arrangement of pixels (Pixel), it can be mainly divided into three types, which are Frame Packing, Side by Side, and Top and Bottom. Digital data represents the arrangement of images.
正常来说，当显示器持续地接收画面，显示器并无法从画面得知该画面是2D画面或者是3D画面，所以显示器会判断来源讯号处于稳定状态。然而当来源讯号相异时，例如，显示器所接收的来源讯号由720p讯号转换为1080p讯号时，显示器会判断来源讯号处于不稳定状态。在此种不稳定状态下，显示器可以侦测到此不稳定状态而重新采用正确的显示格式，也就是说，显示器采用的显示格式与来源讯号的输入格式是一致的(例，同为3D画面的格式)，因此显示器可以正常输出显示画面。Normally, when the display continues to receive images, the display cannot tell whether the image is a 2D image or a 3D image from the image, so the display will determine that the source signal is in a stable state. However, when the source signals are different, for example, when the source signal received by the monitor is converted from a 720p signal to a 1080p signal, the monitor will judge that the source signal is unstable. In this unstable state, the monitor can detect this unstable state and re-use the correct display format, that is to say, the display format adopted by the monitor is consistent with the input format of the source signal (for example, both are 3D screens) format), so the monitor can output the display screen normally.
然而，当讯号源维持原讯号送出,只是画面由2D画面转换成态样为「影像左右并排」或者是「影像上下并排」的3D画面时，虽然画面与数字资料已经改变，但现有的显示器却仍会判定来源讯号处于稳定状态。所以现有的显示器不会重新采用正确的显示格式，使得其所采用的显示格式与来源讯号的输入格式是不一致的，因而造成无法正确显示画面的现象。However, when the signal source maintains the original signal transmission, but the picture is converted from a 2D picture to a 3D picture with "images side by side" or "images side by side", although the picture and digital data have changed, the existing display However, the source signal is still determined to be in a stable state. Therefore, the existing display will not re-adopt the correct display format, making the display format adopted by it inconsistent with the input format of the source signal, thus resulting in the phenomenon that the image cannot be displayed correctly.
此时，使用者必须重新插拔高清晰度多媒体接口的连接器(Cable)或重新启动显示器，使得显示器得以重新采用与来源讯号的输入格式一致的显示格式，才能正常输出显示画面。然此种解决方式却会造成使用者使用上的不便。At this time, the user must re-plug the connector (Cable) of the high-definition multimedia interface or restart the display, so that the display can re-adopt the same display format as the input format of the source signal, so that the display image can be output normally. However, this solution will cause inconvenience to the user.

本发明的另一目的在于提供一种预防讯号切换导致画面显示异常的显示设备。Another object of the present invention is to provide a display device that prevents abnormal picture display caused by signal switching.
本发明预防讯号切换导致画面显示异常的显示设备，包含一缩放控制器，及一微处理器。The present invention prevents signal switching from causing abnormal picture display. The display device includes a scaling controller and a microprocessor.
该缩放控制器用于接收一影像讯号。The scaling controller is used for receiving an image signal.
该微处理器与该缩放控制器电连接,并用于根据该影像讯号获得一对应该影像讯号的目前时序资料。The microprocessor is electrically connected with the scaling controller, and is used for obtaining the current timing data corresponding to the image signal according to the image signal.
该微处理器根据该目前时序资料与一默认的初始时序资料判断该影像讯号是否处于稳定状态。若该影像讯号处于稳定状态，则该微处理器判断该缩放控制器是否已产生一影像画面；若该影像讯号处于非稳定状态，则该缩放控制器不产生任何的影像画面。The microprocessor judges whether the image signal is in a stable state according to the current timing data and a default initial timing data. If the image signal is in a stable state, the microprocessor judges whether the scaling controller has generated an image frame; if the image signal is in an unsteady state, the scaling controller does not generate any image frame.
若该缩放控制器已产生该影像画面，则该微处理器判断该目前时序资料是否包含一3D格式指示资料。If the zoom controller has generated the image frame, the microprocessor judges whether the current time series data includes a 3D format instruction data.
若该目前时序资料包含该3D格式指示资料，则该微处理器将一目前影像格式设定为该输入讯号的3D格式；若该时序资料不包含该3D格式指示资料，则该微处理器将该目前影像格式设定为2D格式。If the current timing data includes the 3D format indication data, the microprocessor sets a current image format as the 3D format of the input signal; if the timing data does not include the 3D format indication data, the microprocessor sets The current image format is set to 2D format.

本发明的有益效果在于：该微处理器会持续地判断该目前时序资料是否包含该3D格式指示资料，使得该显示影像格式与该目前影像格式匹配，而无需通过使用者重新插拔高清晰度多媒体接口的连接器或重新启动该显示设备即可使得该显示器能正常地输出该影像画面，所以确实能达成本发明的目的。The beneficial effect of the present invention is that: the microprocessor will continuously judge whether the current time series data contains the 3D format indication data, so that the display image format matches the current image format, without requiring the user to re-plug the high-definition multimedia The connector of the interface or the display device can be restarted so that the display can output the video picture normally, so the purpose of the present invention can indeed be achieved.

具体实施方式detailed description
下面结合附图及实施例对本发明进行详细说明。The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
参阅图1与图2，本发明预防讯号切换导致画面显示异常的显示设备1的较佳实施例包含一缩放控制器(Scaler)11、一与该缩放控制器11电连接的微处理器(MicroControllerUnit，MCU)12，及一与该缩放控制器11电连接的显示器13。在本较佳实施例中，该显示设备1采用版本为「1.4」的高清晰度多媒体接口接收一影像讯号，例如2D画面或者是3D画面。Referring to Fig. 1 and Fig. 2, the preferred embodiment of the display device 1 which prevents signal switching from causing abnormal picture display in the present invention includes a scaling controller (Scaler) 11, a microprocessor (MicroControllerUnit) electrically connected to the scaling controller 11 , MCU) 12, and a display 13 electrically connected to the scaling controller 11. In this preferred embodiment, the display device 1 adopts a high-definition multimedia interface whose version is "1.4" to receive an image signal, such as a 2D image or a 3D image.
该缩放控制器11用于接收该影像讯号，并产生一影像画面。The scaling controller 11 is used for receiving the image signal and generating an image frame.
该微处理器12用于根据该影像讯号获得一对应该影像讯号的目前时序资料。其中该目前时序资料包括对应该影像讯号的一讯号频率值、一分辨率值，及一扫描频率值。The microprocessor 12 is used for obtaining the current timing data corresponding to the video signal according to the video signal. The current timing data includes a signal frequency value, a resolution value, and a scanning frequency value corresponding to the image signal.
该显示器13用于显示该缩放控制器11产生的该影像画面。The display 13 is used for displaying the image frame generated by the scaling controller 11 .
以下配合一预防讯号切换导致画面显示异常的显示方法，针对上述的缩放控制器11、微处理器12，及显示器13间的互动进一步地说明。The interaction between the zoom controller 11 , the microprocessor 12 and the display 13 will be further described below in conjunction with a display method for preventing signal switching from causing an abnormal display of the screen.
首先，当使用者启动该显示设备1后，该缩放控制器11，及该微处理器12便开始运作。First, when the user activates the display device 1, the scaling controller 11 and the microprocessor 12 start to operate.
如步骤S21所示，该缩放控制器11接收该影像讯号，以供该微处理器12根据该影像讯号，获得对应该影像讯号的该目前时序资料。也就是说，该微处理器12会解析该影像讯号以获得该目前时序资料。其中如同上述所提，该目前时序资料包括该讯号频率值、该分辨率值，及该扫描频率值等信息。As shown in step S21, the scaling controller 11 receives the image signal for the microprocessor 12 to obtain the current timing data corresponding to the image signal according to the image signal. That is to say, the microprocessor 12 analyzes the image signal to obtain the current timing data. As mentioned above, the current timing data includes information such as the signal frequency value, the resolution value, and the scanning frequency value.
如步骤S22所示，该微处理器12根据该目前时序资料与一默认的初始时序资料，判断该影像讯号是否处于稳定状态。在本较佳实施例中，该预设的初始时序资料可以包括对应2D讯号的讯号频率值、分辨率值，及扫描频率值等信息，也可以包括对应3D讯号的讯号频率值、分辨率值，及扫描频率值等信息。As shown in step S22, the microprocessor 12 determines whether the image signal is in a stable state according to the current timing data and a default initial timing data. In this preferred embodiment, the preset initial timing data may include information such as the signal frequency value, resolution value, and scanning frequency value corresponding to the 2D signal, and may also include the signal frequency value and resolution value corresponding to the 3D signal. , and the scanning frequency value and other information.
在本较佳实施例中，当该目前时序资料包括的讯号频率值、分辨率值与扫描频率值，分别与该初始时序资料包括的讯号频率值、分辨率值与扫描频率值相等时，则该微处理器12判断该影像讯号处于稳定状态。换句话说，若该目前时序资料包括的讯号频率值、分辨率值与扫描频率值其中至少一者，与该初始时序资料包括的讯号频率值、分辨率值与扫描频率值不相等时，则该微处理器12判断该影像讯号处于不稳定状态。一般而言，当该微处理器12判断该影像讯号处于不稳定状态时，该缩放控制器11不会产生任何的影像画面，也就是说，该显示器13无法显示任何的影像画面供用户观赏。In this preferred embodiment, when the signal frequency value, resolution value and scanning frequency value included in the current timing data are respectively equal to the signal frequency value, resolution value and scanning frequency value included in the initial timing data, then The microprocessor 12 judges that the image signal is in a stable state. In other words, if at least one of the signal frequency value, resolution value, and scanning frequency value included in the current timing data is not equal to the signal frequency value, resolution value, and scanning frequency value included in the initial timing data, then The microprocessor 12 determines that the image signal is in an unstable state. Generally speaking, when the microprocessor 12 determines that the video signal is in an unstable state, the scaling controller 11 will not generate any video frames, that is, the display 13 cannot display any video frames for users to watch.
举例来说，假设该目前时序资料的分辨率值为「1280*720」，而该初始时序资料的分辨率值为「1920*1080」，则该微处理器12判断该影像讯号处于不稳定状态，且该缩放控制器11不会产生供该显示器13显示的影像画面。For example, if the resolution value of the current time series data is "1280*720", and the resolution value of the initial time series data is "1920*1080", then the microprocessor 12 judges that the image signal is in an unstable state , and the scaling controller 11 will not generate an image frame for the display 13 to display.
如步骤S23所示，若该影像讯号处于稳定状态，则该微处理器12判断该缩放控制器11是否已产生一影像画面。As shown in step S23, if the video signal is in a stable state, the microprocessor 12 determines whether the scaling controller 11 has generated a video frame.
如步骤S24所示，若该缩放控制器11已产生该影像画面，则该微处理器12判断该目前时序资料是否包含一3D格式指示资料。As shown in step S24, if the zoom controller 11 has generated the image frame, the microprocessor 12 determines whether the current time-series data includes a 3D format instruction data.
在本较佳实施例中，该3D格式指示资料主要由高清晰度多媒体接口架构中的供应商特定信息帧分组的内容结构（HDMIVendorSpecificInfoFramePacketContents）的第五个字节(PB4)中的第七位、第六位，及第五位所组成。更进一步的说，上述三位表示HDMI视频格式（HDMI-Video-Format），当上述三位由高位至低位的排列组合为「010」时，则该微处理器12判断该目前时序资料包含该3D格式指示资料。相反地，当上述三个位由高位至低位的排列组合不为「010」时，则该微处理器12判断该目前时序资料不包含该3D格式指示资料。In this preferred embodiment, the 3D format indication data mainly consists of the seventh bit in the fifth byte (PB4), The sixth, and the fifth. Furthermore, the above-mentioned three digits represent the HDMI video format (HDMI-Video-Format). When the arrangement and combination of the above-mentioned three digits from high to low is "010", the microprocessor 12 judges that the current timing data contains the 3D format instruction data. On the contrary, when the combination of the above-mentioned three bits from high to low is not "010", the microprocessor 12 judges that the current time series data does not contain the 3D format indication data.
值得一提的是，当该影像讯号为3D讯号时，该微处理器12还可根据高清晰度多媒体接口架构中的供应商特定信息帧分组的内容结构的第六个字节(PB5)中的第七位、第六位、第五位，及第四位的排列组合，判断该影像讯号为何种态样的3D讯号，即上述四位表示3D结构（3D-Structure）。It is worth mentioning that when the video signal is a 3D signal, the microprocessor 12 can also use the sixth byte (PB5) of the content structure of the supplier-specific information frame grouping in the high-definition multimedia interface architecture. The permutation and combination of the seventh, sixth, fifth, and fourth bits of the image signal determines what kind of 3D signal the image signal is, that is, the above four bits indicate the 3D structure (3D-Structure).
举例来说，假设上述四位由高位至低位的排列组合为「0000」时，则该微处理器12判断该影像讯号的态样为「影像框封装」。类似地，假设上述四位由高位至低位的排列组合为「1000」时，则该微处理器12判断该影像讯号的态样为「影像左右并排」。类似地，假设上述四位由高位至低位的排列组合为「0110」时，则该微处理器12判断该影像讯号的态样为「影像上下并排」。For example, assuming that the arrangement of the above four bits from high to low is "0000", the microprocessor 12 judges that the image signal is "image frame package". Similarly, assuming that the arrangement of the above four bits from high to low is "1000", the microprocessor 12 judges that the image signal is "images side by side". Similarly, assuming that the arrangement of the above four bits from high to low is "0110", the microprocessor 12 judges that the image signal is "images side by side".
如步骤S25与步骤S26所示，若该目前时序资料包含该3D格式指示资料，则该微处理器12将一目前影像格式设定为该输入讯号的3D格式。若该目前时序资料不包含该3D格式指示资料，则该微处理器12将该目前影像格式设定为2D格式。在本较佳实施例中，该目前影像格式为一用来代表该影像讯号的影像格式的变量。也就是说，该微处理器12会根据该目前时序资料包含该3D格式指示资料与否，将该目前影像格式设定为该输入讯号的3D格式或2D格式。As shown in steps S25 and S26, if the current timing data includes the 3D format indication data, the microprocessor 12 sets a current image format as the 3D format of the input signal. If the current time series data does not include the 3D format indication data, the microprocessor 12 sets the current image format as 2D format. In this preferred embodiment, the current video format is a variable used to represent the video format of the video signal. That is to say, the microprocessor 12 will set the current image format as the 3D format or 2D format of the input signal according to whether the current timing data includes the 3D format indication data.
如步骤S27所示，该微处理器12判断该目前影像格式是否与一默认的显示影像格式匹配。其中该显示影像格式默认为该输入讯号的3D格式与2D格式其中一者。也就是说，该默认的显示影像格式代表该显示器13已经在显示中的影像画面的影像格式，而该目前影像格式则代表该缩放控制器11刚接收到的影像讯号的影像格式。As shown in step S27, the microprocessor 12 determines whether the current image format matches a default display image format. The display image format defaults to one of the 3D format and the 2D format of the input signal. That is to say, the default display image format represents the image format of the image frame being displayed by the display 13 , and the current image format represents the image format of the image signal just received by the scaling controller 11 .
如步骤S28所示，若该目前影像格式与该显示影像格式不匹配，则将该显示影像格式设定为该目前影像格式。也就是说，当显示中的影像画面的影像格式与刚接收到的影像讯号的影像格式不相同时，该微处理器12会重新将该显示影像格式设定为该目前影像格式。As shown in step S28, if the current image format does not match the display image format, then the display image format is set as the current image format. That is to say, when the image format of the image frame being displayed is different from the image format of the image signal just received, the microprocessor 12 will reset the display image format to the current image format.
举例来说，假设该显示影像格式为2D格式，而该目前影像格式为3D格式，则该微处理器12会将该显示影像格式重新设定为3D格式。类似地，假设该显示影像格式为3D影像左右并排格式，而该目前影像格式为3D影像上下并排格式，则该微处理器12会将该显示影像格式重新设定为3D影像上下并排格式，使得显示中的影像画面的影像格式与刚接收到的影像讯号的影像格式是一致的。For example, if the display image format is 2D format and the current image format is 3D format, the microprocessor 12 resets the display image format to 3D format. Similarly, if the display image format is a 3D image side-by-side format, and the current image format is a 3D image top-bottom format, then the microprocessor 12 will reset the display image format to a 3D image top-bottom format, so that The video format of the video frame being displayed is consistent with the video format of the video signal just received.
又，若该目前影像格式与该显示影像格式匹配，则代表显示中的影像画面的影像格式与刚接收到的影像讯号的影像格式是相同的，因此不存在影像格式不一致而导致该缩放控制器11无法正确显示画面的问题。所以该缩放控制器11将持续地接收影像讯号，以递归地进行本发明的步骤。Also, if the current image format matches the display image format, it means that the image format of the image frame being displayed is the same as the image format of the image signal just received, so there is no image format inconsistency that causes the scaling controller to 11 The problem that the screen cannot be displayed correctly. Therefore, the scaling controller 11 will continue to receive video signals to recursively perform the steps of the present invention.
如步骤S29所示，该缩放控制器11根据该显示影像格式重新产生该影像画面。此刻该显示影像格式与该目前影像格式已一致，所以该缩放控制器11得以产生供该显示器13显示的该影像画面。As shown in step S29, the scaling controller 11 regenerates the image frame according to the display image format. Now the display image format is consistent with the current image format, so the zoom controller 11 can generate the image frame for the display 13 to display.
值得一提的是，在步骤S23中，虽然该影像讯号处于稳定状态，但若该缩放控制器11尚未产生该影像画面时，则会进行下列步骤S31至步骤S34。It is worth mentioning that in step S23, although the image signal is in a stable state, if the zoom controller 11 has not generated the image frame, the following steps S31 to S34 will be performed.
如步骤S31所示，该微处理器12判断该目前时序资料是否包含该3D格式指示资料。其中该3D格式指示资料的判断细节如同步骤S24所描述，所以不再赘述。As shown in step S31, the microprocessor 12 determines whether the current time-series data includes the 3D format indication data. The determination details of the 3D format instruction data are as described in step S24, so details are not repeated here.
如步骤S32与步骤S33所示，若该目前时序资料包含该3D格式指示资料，则将一显示影像格式设定为该输入讯号的3D格式，若该目前时序资料不包含该3D格式指示资料，则将该显示影像格式设定为2D格式。As shown in steps S32 and S33, if the current timing data includes the 3D format indication data, then set a display image format as the 3D format of the input signal; if the current timing data does not include the 3D format indication data, Then the display image format is set to 2D format.
由于此刻该缩放控制器尚未产生该影像画面，因此并不存在显示中的影像画面的影像格式与刚接收到的影像讯号的影像格式不一致的问题。而该微处理器12仍需将该显示影像格式设定为2D格式或者是该输入讯号的3D格式其中一者，以做为该缩放控制器11产生影像画面时的依据。Since the scaling controller has not generated the image frame at this moment, there is no problem that the image format of the image frame being displayed is inconsistent with the image format of the image signal just received. However, the microprocessor 12 still needs to set the display image format to one of the 2D format or the 3D format of the input signal, as the basis for the scaling controller 11 to generate the image frame.
如步骤S34所示，该缩放控制器11根据该显示影像格式产生该影像画面。举例来说，假设该显示影像格式为2D格式，则该缩放控制器11产生供该显示器13显示的为2D格式的影像画面。类似地，假设该显示影像格式为3D格式，则该缩放控制器11产生供该显示器13显示的为3D格式的影像画面。As shown in step S34, the scaling controller 11 generates the image frame according to the display image format. For example, assuming that the displayed image format is in 2D format, the scaling controller 11 generates an image frame in 2D format for display by the display 13 . Similarly, assuming that the displayed image format is in 3D format, the scaling controller 11 generates an image frame in 3D format for display by the display 13 .
由以上说明可知，本发明的设计具有下述功效：As can be seen from the above description, the design of the present invention has the following effects:
当该影像讯号处于稳定状态时，该微处理器仍会持续地判断该目前时序资料是否包含该3D格式指示资料，以将该目前影像格式设定为3D格式或者是2D格式，并使得该显示影像格式与该目前影像格式匹配，使得该显示器能正常地输出该影像画面，而无需通过使用者重新插拔高清晰度多媒体接口的连接器或重新启动该显示设备，所以确实能达成本发明的目的。When the image signal is in a stable state, the microprocessor will continue to judge whether the current timing data contains the 3D format indication data, so as to set the current image format as 3D format or 2D format, and make the display The image format matches the current image format, so that the display can normally output the image screen, without the need for the user to re-plug the connector of the high-definition multimedia interface or restart the display device, so the purpose of the present invention can indeed be achieved .
