Description
技术领域technical field
本发明涉及拼接显示技术领域，特别是涉及超高清分辨率图像同步显示方法和系统。The present invention relates to the technical field of splicing display, in particular to a method and system for synchronously displaying ultra-high-definition resolution images.
背景技术Background technique
超高清分辨率（Ultra High-Definition）包括4k（3840x2160）、8k（7680x4320）等，超高清分辨率图像能够带十分细腻显示效果，它一个画面能够携带巨大的信息量，同时画面内部的细节非常清晰，超高清分辨率图像用在拼接显示装置上显示，效果更加震撼。Ultra High-Definition (Ultra High-Definition) includes 4k (3840x2160), 8k (7680x4320), etc. Ultra-high-definition resolution images can bring a very delicate display effect, and one picture can carry a huge amount of information, and the details inside the picture are very detailed. Clear, ultra-high-definition resolution images are displayed on the splicing display device, and the effect is even more shocking.
超高清分辨率图像每一帧的数据量大，通过普通的信号通道内无法传输超高清分辨率图像。为了能够实现超高清分辨率图像显示，传统技术中常按照分辨率对当前超高清分辨率图像信号进行分割，分割后的超高分辨率图像子信号适于单信号通道传输。采用对应个数的信号通道分别将分割后的超高分辨率图像子信号传输至拼接显示装置；在拼接显示装置上显示各个超高分辨率图像子信号。由于分割成了多个子信号，所以在拼接显示装置上显示时会导致子画面不同步问题，从而出现图像撕裂现象，影响显示效果。The amount of data per frame of ultra-high-definition resolution images is large, and ultra-high-definition resolution images cannot be transmitted through ordinary signal channels. In order to realize ultra-high-definition resolution image display, the current ultra-high-definition resolution image signal is often divided according to the resolution in traditional technology, and the divided ultra-high-resolution image sub-signals are suitable for single signal channel transmission. The divided ultra-high-resolution image sub-signals are respectively transmitted to the splicing display device by using corresponding number of signal channels; and each ultra-high-resolution image sub-signal is displayed on the splicing display device. Since the sub-signals are divided into multiple sub-signals, when displayed on the spliced display device, the sub-pictures will be out of sync, resulting in image tearing and affecting the display effect.
为了实现子画面同步，是通过预先在拼接显示装置上为每个信号通道开出子窗口，子窗口的坐标与超高分辨率图像子信号的分辨率对应，各个子窗口先隐藏，待所有子窗口均通过对应的信号通道接收到对应的超高分辨率图像子信号后，再统一显示所述超高分辨率图像子信号，这种同步方式是在显示端进行等待，实现同步，但是随着超高清分辨率图像的分辨率越来越大，实时性要求越来越高，这种技术在显示端进行等待方式已经无法适应超高清分辨率图像显示要求。In order to achieve sub-picture synchronization, sub-windows are opened for each signal channel on the splicing display device in advance. The coordinates of the sub-windows correspond to the resolution of the sub-signals of ultra-high resolution images. After the windows receive the corresponding ultra-high-resolution image sub-signals through the corresponding signal channels, the ultra-high-resolution image sub-signals are displayed uniformly. This synchronization method is to wait at the display end to achieve synchronization, but with The resolution of ultra-high-definition resolution images is getting larger and higher, and the real-time requirements are getting higher and higher. The waiting method of this technology at the display end can no longer meet the requirements of ultra-high-definition resolution image display.
为了显示超高清分辨率图像，现阶段在拼接显示装置上采用较多的处理方式，通常是采用提高信号处理器时钟频率的方法，如输入信号为3840x216030Hz，像素时钟297MHz，信号处理器的运行时钟必须高于像素时钟，但这种技术也随着超高清分辨率图像的分辨率的增大而产生明显的缺陷，例如当图像分辨率再增加到8k或者图像帧率再提高时，一般信号处理的频率就无法满足像素时钟要求，信号处理器的工作频率将成为瓶颈，而且频率高越高，信号处理器的成本就成倍增加，导致超高清分辨率图像显示成本较高。In order to display ultra-high-definition resolution images, more processing methods are used on splicing display devices at this stage, usually by increasing the clock frequency of the signal processor. For example, the input signal is 3840x216030Hz, the pixel clock is 297MHz, and the operating clock of the signal processor It must be higher than the pixel clock, but this technology also has obvious defects with the increase of the resolution of ultra-high-definition resolution images. For example, when the image resolution is increased to 8k or the image frame rate is increased, the general signal processing If the frequency cannot meet the pixel clock requirements, the operating frequency of the signal processor will become a bottleneck, and the higher the frequency, the cost of the signal processor will increase exponentially, resulting in a higher cost for ultra-high-definition resolution image display.

具体实施方式Detailed ways
以下针对本发明超高清分辨率图像同步显示方法和系统的各实施例进行详细的描述。Various embodiments of the method and system for synchronously displaying ultra-high-definition resolution images of the present invention will be described in detail below.
如图1所示，为本发明超高清分辨率图像同步显示方法实施例的流程示意图，包括步骤：As shown in Figure 1, it is a schematic flow diagram of an embodiment of the method for synchronously displaying ultra-high-definition resolution images of the present invention, including steps:
步骤S101：获取各个信号通道对应的子图像信号；其中，子图像信号为所需显示的超高清分辨率图像信号分割获得的图像信号；Step S101: Obtain sub-image signals corresponding to each signal channel; wherein, the sub-image signals are image signals obtained by dividing the ultra-high-definition resolution image signal to be displayed;
其中，子图像信号可以根据分辨率对当前超高清分辨率图像信号进行分割得到，分割后的子图像信号适于单信号通道传输。Wherein, the sub-image signal can be obtained by dividing the current ultra-high-definition resolution image signal according to the resolution, and the divided sub-image signal is suitable for single signal channel transmission.
在其中一个实施例中，步骤S101包括：In one of the embodiments, step S101 includes:
根据超高清分辨率与单信号通道分辨率的倍数关系对超高清分辨率图像信号进行分割，获得子图像信号，并确定处理超高清分辨率图像信号的信号通道个数；Segment the ultra-high-definition resolution image signal according to the multiple relationship between the ultra-high-definition resolution and the resolution of a single signal channel, obtain sub-image signals, and determine the number of signal channels for processing the ultra-high-definition resolution image signal;
根据信号通道个数选取信号通道，通过各信号通道获取对应的子图像信号。Signal channels are selected according to the number of signal channels, and corresponding sub-image signals are obtained through each signal channel.
该实施例是统一分割的方式，即在进入信号通道前，先将超高清分辨率图像信号按照倍数进行分割，然后将各子图像信号通过信号通道进行处理和传输。例如当输入信号为3840x216030Hz的情况下，其数据流是1920x108060Hz的两倍，所以先将图像信号分割成两份，用两个信号处理通道合并完成图像信号的实时显示。This embodiment adopts a unified segmentation method, that is, before entering the signal channel, the ultra-high-definition resolution image signal is first divided according to multiples, and then each sub-image signal is processed and transmitted through the signal channel. For example, when the input signal is 3840x216030Hz, its data flow is twice that of 1920x108060Hz, so the image signal is divided into two parts first, and the two signal processing channels are combined to complete the real-time display of the image signal.
在另一个实施例中，步骤S101包括：In another embodiment, step S101 includes:
根据超高清分辨率与单信号通道分辨率的倍数关系确定处理超高清分辨率图像信号的信号通道个数；Determine the number of signal channels for processing ultra-high-definition resolution image signals according to the multiple relationship between ultra-high-definition resolution and single-signal channel resolution;
根据信号通道个数选取信号通道，并将超高清分辨率图像信号输入各信号通道；Select signal channels according to the number of signal channels, and input ultra-high-definition resolution image signals into each signal channel;
通过各信号通道分别将超高清分辨率图像信号按照信号通道个数进行分割，获得各信号通道的子图像信号。The ultra-high-definition resolution image signal is divided according to the number of signal channels through each signal channel to obtain sub-image signals of each signal channel.
该实施例是先确定信号通道个数，然后将完整的超高清分辨率图像信号输入到每个信号通道中，控制信号通道分割该信号通道欲处理的子图像信号。该处理过程可以和后续信号通道根据拼接显示装置屏幕个数进行剪切过程同时进行。比如，拼接显示装置有四个显示屏，传统技术在单信号通道中需要剪切成四份。在本方案中，如果有三个信号通道同时处理该路超高清分辨率图像信号，则在该信号通道中，对应剪切四份倍超高清分辨率图像信号大小的图像信号，然后进行后续处理。这种方式可以减少在进入信号通道前分割处理时间，从而加快整个运行处理速度。In this embodiment, the number of signal channels is determined first, and then a complete ultra-high-definition resolution image signal is input into each signal channel, and the signal channel is controlled to divide the sub-image signals to be processed by the signal channel. This processing process can be carried out simultaneously with the subsequent signal channel cutting process according to the number of screens of the spliced display device. For example, a splicing display device has four display screens, and the traditional technology needs to be cut into four parts in a single signal channel. In this scheme, if there are three signal channels processing the ultra-high-definition resolution image signal at the same time, in this signal channel, four corresponding cuts The image signal is twice the size of the ultra-high-definition resolution image signal, and then undergoes subsequent processing. This approach can reduce the processing time of splitting before entering the signal channel, thereby speeding up the processing speed of the whole operation.
另外，在根据信号通道个数选取信号通道过程中，可以任意选取信号通道。任意两个以上的通道可以自由组合。当用户开启多个普通信号窗口后，任意关闭两个或者多个普通窗口，被关闭的信号通道可以自由组合开出超高清分辨率图像窗口。In addition, in the process of selecting signal channels according to the number of signal channels, signal channels may be selected arbitrarily. Any two or more channels can be combined freely. When the user opens multiple ordinary signal windows, and closes two or more ordinary windows arbitrarily, the closed signal channels can be freely combined to open an ultra-high-definition resolution image window.
步骤S102：将各个信号通道的帧率转换处理的读写指针和帧缓存处理的读写指针分别进行同步，并根据同步后的读写指针处理子图像信号；Step S102: Synchronize the read/write pointers of the frame rate conversion processing of each signal channel and the read/write pointers of the frame buffer processing respectively, and process the sub-image signal according to the synchronized read/write pointers;
本步骤目的是将所有选中的信号通道的帧率转换的读写指针一致（同步），将所有选中的信号通道的帧缓存的读写指针一致（同步），从而实现各个信号处理通道处理的子画面在进行帧率转换及其帧缓存时能够完全同步，保证最后合成图像时子画面是从同一个超高清图像中分割出来的，从而不会造成后端的图像撕裂。且无需在拼接显示装置上等待接收到所有子信号后再统一显示，实时性好。在处理超高清分辨率图像信号时，任意两个或者多个信号通道都可以相互共享读写指针。The purpose of this step is to make the read and write pointers of frame rate conversion of all selected signal channels consistent (synchronized), and the read and write pointers of frame buffers of all selected signal channels The screen can be fully synchronized during frame rate conversion and frame buffering, ensuring that the sub-picture is segmented from the same ultra-high-definition image when the final image is synthesized, so as not to cause image tearing at the back end. Moreover, there is no need to wait for all the sub-signals to be received on the splicing display device before being displayed uniformly, and the real-time performance is good. When processing ultra-high-definition resolution image signals, any two or more signal channels can share read and write pointers with each other.
在其中一个实施例中，步骤S102包括：In one of the embodiments, step S102 includes:
将各信号通道其中一个信号通道设为主信号通道，其它信号通道设为副信号通道；Set one of the signal channels as the main signal channel, and the other signal channels as the secondary signal channel;
控制主信号通道根据超高清分辨率图像信号的帧率和拼接显示装置显示信号的帧率跳转帧率转换的读写指针和帧缓存的读写指针，对该信号通道对应的子图像信号进行剪切、帧率转换、缩放和帧缓存；Control the main signal channel according to the frame rate of the ultra-high-definition resolution image signal and the frame rate of the display signal of the splicing display device to jump the read-write pointer of the frame rate conversion and the read-write pointer of the frame buffer to perform the sub-image signal corresponding to the signal channel Clipping, frame rate conversion, scaling and frame buffering;
控制各副信号通道根据主信号通道的帧率转换的读写指针和帧缓存的读写指针，对应对该信号通道的子图像信号进行剪切、帧率转换、缩放和帧缓存。Control the reading and writing pointers of each auxiliary signal channel according to the frame rate conversion of the main signal channel and the reading and writing pointers of the frame buffer, and perform cutting, frame rate conversion, scaling and frame buffering of the sub-image signal corresponding to the signal channel.
本实施例是读写指同步的一种实现方式，This embodiment is an implementation of reading and writing finger synchronization.
其中一个通道作为主信号处理通道，其它通道为副信号处理通道，副信号处理通道统一使用主信号处理通道的帧读写指针。当用户开启多个普通信号窗口后，任意关闭两个或者多个普通窗口，被关闭的信号通道可以自由组合开出超高清分辨率图像窗口。One of the channels is used as the main signal processing channel, and the other channels are sub-signal processing channels, and the sub-signal processing channels uniformly use the frame read and write pointers of the main signal processing channel. When the user opens multiple ordinary signal windows, and closes two or more ordinary windows arbitrarily, the closed signal channels can be freely combined to open an ultra-high-definition resolution image window.
帧率转换指针共享必须保证各个通道运行在同一个时钟域中，当使用多组DDR控制器实现帧缓存时，各个DDR控制器需要共享同一个PLL，实现所用DDR控制器时钟域统一。Frame rate conversion pointer sharing must ensure that each channel runs in the same clock domain. When multiple sets of DDR controllers are used to implement frame buffering, each DDR controller needs to share the same PLL to realize the unified clock domain of the DDR controllers used.
步骤S103：将通过信号通道处理的子图像信号进行图像合并，并在拼接显示装置上进行显示。Step S103: Combine the sub-image signals processed through the signal channel, and display them on the spliced display device.
图像合并是在每个信号通道后端，将所有分割后的子图像信号进行合并，然后将合并后图像信号传输到拼接显示装置上，从而可以实现图像信号的完整显示，也避免不合并直接显示可能导致的画面不均匀或显示不是同一副画面的情况。比如，当选择其中一通道作为超高清分辨图像主信号处理通道时，图像合成模块选择相应的一个或者多个副信号处理通道的输出的子画面与主信号处理通道的输出的子画面合并；当某个通道选择为副信号处理通道时，该通道的不做图像合并处理；当某通道不处理超高清分辨率图像时，该通道直接输出本通道处理的结果。Image merging is to combine all the divided sub-image signals at the back end of each signal channel, and then transmit the combined image signals to the splicing display device, so as to realize the complete display of image signals and avoid direct display without merging It may cause unevenness of the picture or the situation that the display is not the same picture. For example, when one of the channels is selected as the main signal processing channel of the ultra-high-definition resolution image, the image synthesis module selects the sub-picture output of the corresponding one or more sub-signal processing channels to merge with the sub-picture output of the main signal processing channel; When a certain channel is selected as the sub-signal processing channel, the channel does not perform image merging processing; when a certain channel does not process ultra-high-definition resolution images, this channel directly outputs the result of this channel's processing.
在其中一个实施例中，当有多路超高清分辨率图像信号同时处理时，在拼接显示装置上进行显示的步骤包括：In one of the embodiments, when multiple channels of ultra-high-definition resolution image signals are processed simultaneously, the step of displaying on the spliced display device includes:
将各路超高清分辨率图像合并得到的图像信号进行叠加；Superimpose the image signals obtained by merging the ultra-high-definition resolution images of various channels;
将叠加后的图像信号在拼接显示装置上进行显示。The superimposed image signals are displayed on the spliced display device.
将每路超高清图像进行的子图像信号进行合并后，得到该路超高清图像的合并图像，将各路超高清图像的合并图像进行叠加，即可实现多路高清图像信号同时处理的情况。After merging the sub-image signals of each channel of ultra-high-definition images, a combined image of the channel of ultra-high-definition images is obtained, and the combined images of each channel of ultra-high-definition images are superimposed to realize simultaneous processing of multiple channels of high-definition image signals.
本发明兼容原有的开窗方式，当输入信号不是超高清分辨率图像时，每个信号处理通道可以独自完成一个信号的开窗，在这种情况下，帧率转换指针共享模块将被直通，各个信号处理通道中的帧率转换和帧缓存按各自的输入信号和拼接显示装置显示信号的帧率自由跳转读写指针。每个信号通道不进行图像合成工作。即当信号通道在不合并处理超高清分辨率图像时，可以独自处理一路普通输入信号，实现在拼接显示装置上多路信号开窗。The present invention is compatible with the original windowing method. When the input signal is not an ultra-high-definition resolution image, each signal processing channel can independently complete the windowing of a signal. In this case, the frame rate conversion pointer shared module will be passed through , the frame rate conversion and frame buffer in each signal processing channel can freely jump read and write pointers according to the frame rate of the respective input signal and display signal of the splicing display device. Each signal channel does not perform image compositing work. That is, when the signal channels are not merged to process ultra-high-definition resolution images, one common input signal can be independently processed to realize windowing of multiple signals on the splicing display device.
根据上述方法，本发明还提供一种超高清分辨率图像同步显示系统，如图2所示，为本发明超高清分辨率图像同步显示系统实施例的结构示意图，包括：According to the above method, the present invention also provides an ultra-high-definition resolution image synchronous display system, as shown in FIG. 2 , which is a schematic structural diagram of an embodiment of the ultra-high-definition resolution image synchronous display system of the present invention, including:

根据超高清分辨率3840x216030Hz与单信号通道分辨率1920x108060Hz的倍数关系2确定处理超高清分辨率图像信号的信号通道个数为2；According to the multiple relationship 2 of ultra-high-definition resolution 3840x216030Hz and single signal channel resolution 1920x108060Hz, the number of signal channels for processing ultra-high-definition resolution image signals is determined to be 2;
根据信号通道个数选取信号通道0和信号通道x（x可以是除信号通道0外的任意一个信号通道），并将超高清分辨率图像信号输入各信号通道Select signal channel 0 and signal channel x according to the number of signal channels (x can be any signal channel except signal channel 0), and input ultra-high-definition resolution image signals into each signal channel
超高清分辨率输入信号处理器后，信号通道0的剪切模块剪切超高清分辨率图像的上半帧，信号通道x的剪切模块剪切超高清分辨率图像的下半帧。After the ultra-high-definition resolution is input to the signal processor, the cutting module of signal channel 0 cuts the upper half frame of the ultra-high-definition resolution image, and the cutting module of signal channel x cuts the lower half frame of the ultra-high-definition resolution image.
信号通道0为主信号处理通道，信号通道0根据输入信号的帧率及输出帧率要求跳转帧率转换模块及帧缓存模块的指针，实现对上半子画面的帧率转换及缩放。The signal channel 0 is the main signal processing channel, and the signal channel 0 jumps the frame rate conversion module and the pointer of the frame buffer module according to the frame rate of the input signal and the output frame rate to realize the frame rate conversion and scaling of the upper half of the sub-picture.
信号通道x为副信号处理通道，信号通道x中的帧率转换模块及帧缓存模块使用信号通道0中的帧读写指针进行跳转，实现与信号通道0中的子画面帧率转换同步跳转，保证上下两个子画面在信号通道0和信号通道x中处理完全同步。Signal channel x is a sub-signal processing channel. The frame rate conversion module and frame buffer module in signal channel x use the frame read and write pointer in signal channel 0 to jump, and realize the synchronous jump with the sub-picture frame rate conversion in signal channel 0. Turn to ensure that the upper and lower sub-pictures are completely synchronized in the processing of signal channel 0 and signal channel x.
信号通道0的图像合成模块将本通道输出的上半帧子画面与信号通道x输出的下半帧子画面合成为一帧完整的图像，并输出到叠加模块。The image synthesis module of signal channel 0 synthesizes the upper half-frame sub-picture output by this channel and the lower half-frame sub-picture output by signal channel x into a complete frame, and outputs it to the overlay module.
信号通道x的图像合成模块不输出图像信号，叠加模块把信号通道0输出的图像与其它信号通道输出的开窗信号叠加后输出。The image synthesis module of the signal channel x does not output the image signal, and the superposition module superimposes the image output by the signal channel 0 with the windowed signals output by other signal channels and then outputs it.
