具体实施方式
为使本申请的目的、实施方式和优点更加清楚，下面将结合本申请示例性实施例中的附图，对本申请示例性实施例进行清楚、完整地描述，显然，所描述的示例性实施例仅是本申请一部分实施例，而不是全部的实施例。
为便于用户使用，显示设备上通常会设置各种外部装置接口，以便于连接不同的外设设备或线缆以实现相应的功能。而在显示设备的接口上连接有高清晰度的摄像头时，如果显示设备的硬件系统没有接收源码的高像素摄像头的硬件接口，那么就会导致无法将摄像头接收到的数据呈现到显示设备的显示屏上。
并且，受制于硬件结构，传统显示设备的硬件系统仅支持一路硬解码资源，且通常最大仅能支持4K分辨率的视频解码，因此当要实现边观看网络电视边进行视频聊天时，为了不降低网络视频画面清晰度，就需要使用硬解码资源(通常是硬件系统中的GPU)对网络视频进行解码，而在此情况下，只能采取由硬件系统中的通用处理器(例如CPU)对视频进行软解码的方式处理视频聊天画面。
采用软解码处理视频聊天画面，会大大增加CPU的数据处理负担，当CPU的数据处理负担过重时，可能会出现画面卡顿或者不流畅的问题。在一些实施例中，受制于CPU的数据处理能力，当采用CPU软解码处理视频聊天画面时，通常无法实现多路视频通话，当用户想要再同一聊天场景同时与多个其他用户进行视频聊天时，会出现接入受阻的情况。
本申请一些实施方式公开了一种双硬件系统架构，以实现多路视频聊天数据(至少一路本地视频)。

在一些实施方式中，对于双芯片的智能电视200而言，由于A芯片及N芯片中可能分别安装有独立的操作系统，从而使显示设备200中存在两个在独立但又存在相互关联的子系统。例如，A芯片和N芯片均可以独立安装有安卓(Android)及各类APP，使得每个芯片均可以实现一定的功能，并且使A芯片和N芯片协同实现某项功能。
在一些实施方式中，非双芯片的智能电视200(例如单芯片智能电视)，存在一个系统芯片，操作系统控制智能电视的所有功能实现。
第一芯片(一些实施例中称之为A芯片)和第二芯片(一些实施例中也称之为N芯片)均可用于接收视频信号。其中视频信号包括：来源于网络媒体的网络视频信号、来源于自广电网络的有线视频信号和预先存储的本地视频信号中的至少一种。在在一些实施例中应用过程中，第一芯片用于接收网络视频信号以及本地视频信号中的至少一种。第二芯片用于接收有线视频信号，以及第一芯片传输过来的网络视频信号本地视频信号中的至少一种。
以第一芯片用于接收网络视频信号为例。通常，网络视频信号包括：视频层信号。第一芯片中设置有图形层信号发生器，第一芯片在接收网络视频信号的同时，图形层信号发生器根据需求产生相应的图形层信号，此时，第一芯片同时存在视频层信号和图形层信号。第一芯片需要将视频层信号和图形层信号发送至第二芯片。第二芯片将视频层信号和图形层信号处理后发送至显示设备的显示屏上展示。为了保证播放出来的画面流畅，第二芯片通常需要对接收到的视频信号进行图像处理，例如：运动补偿处理。
在运动补偿的过程中，由于视频层信号都是具有一定的运动矢量的信号，运动补偿技术若只作用于视频层信号，会将视频层信号更流畅、无明显的抖动现象。但是，若第二芯片接收到的信号为视频层信号与图形层信号叠加生成的视频图像信号，由于运动补偿帧中的图形层信号与前后两帧图形层信号相比，必存在像素点的移动。而根据HDMI协议，视频层信号和图形层信号无法在HDMI通道下同时传输，因此第一芯片会将视频层信号以及图形层信号混合后，按照HDMI协议编码成视频图像信号再发送给第二芯片。这样，第二芯片便不能区分其接收到的视频图像信号是否包含有图形层信号，如果继续对上述包含有图形层信号的视频图像信号进行运动补偿处理，便会出现图形层信号对应区域的画面被撕裂的现象。因此，可以采用的一种解决方式为：如果存在图形层时信时，第一芯片向第二芯片发送关闭运动补偿的指示消息，相应的，第二芯片对接收的视频图像信号不再进行运动补偿处理。但是，现有的第三方应用程序在全屏播放视频时，会创建一个透明的图形层叠加在视频层图像之上，此时若直接将运动补偿功能完全关闭，便会出现输出画面抖动严重的现象。
针对上述问题，本申请一些实施例提供了一种图像处理方法应用于显示设备中，该显示设备包括第一芯片、第二芯片和显示屏。图8中示例性示出了一种图像处理方法的流程示意 图。如图8所示，该方法主要包括如下步骤：
S101：第一芯片在将视频层信号与图形层信号叠加生成视频图像信号时，检测所述图形层信号对应的图形层是否为透明层。
本申请一些实施例中，视频层信号可以是视频信号也可以是图像信号。图9中示例性示出了第一芯片对视频层信号和图形层信号的处理流程示意图。如图9所示，第一芯片用于接收视频层信号，其中，视频层信号可以为来源于网络媒体或本地媒体的视频信号，也可以为来源于网络媒体或本地媒体的图像信号，在一些实施例中，可以包括网络电影、电视剧、新闻、综艺节目、广告等视频节目中的至少一种；还包括自拍Dv短片、视频聊天、视频游戏等视频节目中的至少一种。
本申请一些实施例中，图形层信号也称之为OSD(Object Sequence Diagram，屏幕菜单式调节方式)。图形层信号来源于第一芯片内部设置的图形层信号发生器。OSD层信号主要包括用户设置、提示菜单以及第三方应用图层等，在安卓系统中，是由surface finger服务(也可称之为图形层信号发生器)来控制实现的。每个OSD层信号可以称为一个surface，每个surface都具有内容、大小、位置坐标以及透明度这些基本元素。第一芯片在基本元素中确定图形层信号的位置信息，其中所述位置信息为surface的尺寸信息和位置坐标信息分别对应基本元素的大小和位置坐标。
其中，基本元素基于视频层信号帧画面生成，举例说明：视频层信号帧画面的分辨率为1920＊1080，图形层信号的位置信息以每帧画面的左上角为原点进行划定。在一些实施例中，请参阅图10，其中，图10示出的帧画面分辨率1920＊1080，帧画面的左上角为B原点进行划定，图形层画面的左上角为A点。A点相对于B点的相对位置坐标为(m，n)。图形层画面的尺寸信息为(w，h)，相应的位置信息为(m，n，w，h)。
基于第一芯片的上述信号处理过程，当图形层信号发生器有surface输出时，在将视频层信号与图形层信号叠加生成视频图像信号前，通过在所述图形层信号截取图形层图片帧；然后，根据对该图形层图片帧中像素点的像素值的分析结果，判断所述图形层信号对应的图形层是否为透明层。例如，通过检测该图形层图片帧中各像素点的像素值是否均为0，即各像素点的像素值均满足R＝0、B＝0且G＝0时，则说明该图形层信号对应的图形层为透明层，但并不限于该检测方式，还可以采用其它方式、如分区域检测等。
如果所述图形层信号对应的图形层为透明层，则执行步骤S102，否则，则执行步骤S104。
S102：响应于所述图形层信号对应的图形层为透明层，则所述第一芯片将第一指示信息以及所述视频图像信号发送给第二芯片，其中，所述第一指示信息用于指示所述第二芯片对所述视频图像信号中叠加所述图形层的区域进行运动补偿处理。
在一些实施例中，在所述图形层信号对应的图形层为透明层时，第二芯片对视频图像信号解析出的图像帧整帧图像进行运动补偿。
本申请一些实施例中，第一芯片通过HDMI通道与第二芯片相连接，并且在HDMI数据传输协议中，音视频信号采用分时复用的方式进行数据传输，无法分别单独传输OSD层信号与视频层的信号。因此，本申请一些实施例中，第一芯片将视频层信号与图形层信号叠加得到的视频图像信号，通过HDMI通道发送给所述第二芯片。在一些实施例中，第一芯片将图形层信号和视频层信号叠加后转化成符合HDMI协议的视频图像信号，视频图像信号以HDMI数据包的形式存在。其中，视频图像信号的编码方式和视频层信号的编码方式不同。
另外，可以将第一指示信息可以添加至预留的HDMI信息包(packet，或称为Info Frame Type code)中并发送至第二芯片。如采用HDMI协议中的SPD(source product description，产品来源说明)、NVBI(NTSC VBI)这两个预留的信息包，并且此两个信息包在每个图像帧率都会发送，因此，本申请一些实施例将第一指示添加至HDMI信息包中，可以实时传送每帧视频图像信号的图形层信息。
在一些实施例中，第一芯片和第二芯片可以通过另一种传输方式连接，该传输方式无法支持图形层信号和视频层信号的同时分别传输，需要将图形层信号和视频层信号编码成一路视频信号。
S103：所述第二芯片对所述视频图像信号进行运动补偿，生成运动补偿后的图像。
这样，第二芯片会根据该第一指示信息对接收到的视频图像信号中所述位置信息对应的区域的图像进行运动补偿处理、并且除所述位置信息对应的区域以外的图像也继续进行运动补偿，即对视频图像信号对应的全部图像区域均进行运动补偿处理，得到运动补偿后的图像，并继续执行步骤S107。因此，第二芯片可以准确的获知图形层信号对应的图形层是否为透明度状态，并进行相应的处理，可以有效避免当存在图形层信号时，直接关闭运动补偿处理功能所带来的输出画面质量降低的问题。
在一些实施例中，透明层的图形层不影响运动补偿后的显示，因此可以对所述视频图像信号中的整帧进行运动补偿处理。
S104：响应于所述图形层信号对应的图形层不是透明层，则所述第一芯片将第二指示信息和所述视频图像信号发送给第二芯片。其中，所述第二指示信息中包括图形层信号对应的图形层的位置信息。
第一芯片将在surface的基本元素确定图形层信号的大小和位置坐标作为图形层的位置信息，并将该位置信息添加至第二指示信息中，然后将第二指示信息与视频图像信号一同通过HDMI通道发送至第二芯片。其中，第二指示信息可以通过预留HDMI信息包发送给第二芯片。然后，所述第二芯片接收到该第二指示信息和视频图像信号，可以按照步骤S104中所示的方式进行图像处理。
S105：所述第二芯片对所述视频图像信号中除所述位置信息对应的区域以外的图像进行运动补偿、对所述视频图像信号中所述位置信息对应的区域的图像不进行运动补偿。
在一些实施例中，第二芯片根据接收到的位置信息，确定图形层信号在所述视频图像信号中对应的第一区域；确定所述视频图像信号中第一区域之外的第二区域；对所述第二区域的图像进行运动补偿。
其中，第一区域的确定过程可以继续参阅图10。第一芯片发送的位置信息为(m，n，w，h)，其中，图形层信号的画面尺寸信息为(w，h)，位置坐标信息(m，n)。第二芯片根据位置坐标信息(m，n)确定图形层信号的画面的位置，然后根据图形层信号的画面的尺寸信息为(w，h)确定图形层信号的画面在视频图像信号的帧画面占用的区域即为第一区域，然后，在视频图像信号的帧画面去除图形层信号的画面在视频图像信号的帧画面占用的区域剩余的区域即为第二区域，对所述第二区域的图像进行运动补偿。
对第二区域的图像进行运动补偿的过程具体为：第二芯片中的运动补偿模块经过滤掉图形层信号的画面占用的区域(第一区域)对应的像素点，不进行此区域的运动矢量计算及插入补偿帧，对第二区域的像素点进行运动补偿。
可见，本申请一些实施例中第一芯片首先确定图形层信号的位置信息，并将图形层信号和视频层信号叠加后转化为成视频图像信号，然后，将所述位置信息连通视频图像信号一同以HDMI数据包形式发送给第二芯片。第二芯片对所述视频图像信号中除所述位置信息对应的区域以外的图像进行运动补偿，第二芯片将运动补偿后的图像和图形层信号的图像进行拼接以生成运动补偿后的图像。在当前帧视频画面与上一帧(或下一帧)视频画面之间插入该混合后补偿帧，进而，可以避免图形层信号在运动补偿过程中被撕裂问题的出现。
在实际应用的过程中，位置信息对应的第一区域是基于第一芯片接收的视频层信号的分辨率(在本申请一些实施例中也称之为输入分辨率)生成的。第二区域的是基于显示屏的分辨率(在本申请实施例中也称之为显示分辨率)计算。在视频播放的过程中，时常伴随着输入分辨率与显示分辨率不一致的情况。例如：一个网络视频的输入分辨率为1920＊1080，但是，显示屏性能的不同，相应的显示分辨率也不同。4K显示屏的显示分辨率为3840＊2160。FHD(Full High Definition)显示屏的显示分辨率一般只能达1920＊1080。如果N芯片与FHD(Full High Definition)显示屏，便出现输入分辨率与显示分辨率不一致的情况。通常，输入分辨率与显示分辨率不一致会导致第二区域计算结果的不准确性。
下面结合具体实施例对输入分辨率与显示分辨率不一致将会导致的问题作以详细的说明。对于4K显示屏而言，如果网络视频的输入分辨率为1920＊1080，第一芯片发送的位置信息为(0，0，20，30)，相应的，图形层信号的画面的尺寸信息为(20，30)，位置坐标信息(0，0)。在分辨率为1920＊1080的视频信号中图形层信号的画面的尺寸信息为(20，30)。但是，视频播放的过程中，需要将视频信号分辨率转化为显示屏分辨率。转化后的帧画面的分辨率为3840＊2160。此时在3840＊2160分辨率的帧画面上根据图形层信号的画面的尺寸信息为(20，30)，以及，位置坐标信息(0，0)来确定第二区域显然是不准确的。
为了保证第二区域的准确性。可以在运动补偿之前，根据视频层信号的分辨率与所述显示屏的分辨率之间的对应关系，对第一芯片发送的位置信息进行缩放处理，然后根据缩放处理后的位置信息，确定第二区域。也可以，确定所述位置信息在所述视频图像信号中对应的第一区域；所述第二芯片确定所述视频图像信号中第一区域之外的第二区域；然后基于视频层信号的分辨率与所述显示屏的分辨率之间的对应关系与所述显示屏的分辨率之间的对应关系，对于第二区域进行缩放处理。
第一种可能性第二芯片首先判断视频层信号的分辨率与显示屏的分辨率是否一致；如果不一致第二芯片根据显示屏的分辨率与视频层信号的分辨率之间的对应关系，对该位置信息和视频图像信号进行缩放处理，生成调整后的位置信息和调整后的视频图像信号，对调整后的视频图像信号除所述调整后的位置信息对应的区域以外图像进行运动补偿。
下面结合具体实例对第二区域的计算方法作以详细的说明。在一实施例中第二芯片与4K显示屏相连接。对于一网络视频信号而言，图形层信号的尺寸信息为(w，h)，位置信息(m，n)，第一芯片生成的位置信息为(m，n，w，h)；第一芯片发送(m，n，w，h)至第二芯片。显示屏的分辨率为3840＊2160，视频信号的分辨率1920＊1080，第二芯片计算出显示屏分辨率与视频信号分辨率之间的对应关系为2倍。第二芯片基于2倍的对应关系，对视频图像信号的帧画面放大处理，生成帧画面的分辨率为3840＊2160。第二芯片基于2倍的对应关系对(m，n，w，h)放大两倍处理，生成处理后的位置信息(2m，2n，2w，2h)；第二芯片根据新的位置坐标信息(2m，2n)确定图形层信号的帧画面的位置，然后根据新的 尺寸信息为(2w，2h)，确定位置信息在帧画面(帧画面与显示屏分辨率一致)占用的区域，然后，在帧画面去除处理后的位置信息对应的区域在帧画面占用的区域为第一区域，剩余的区域即为第二区域。
最后，第二芯片对第二区域对应的图像进行运动补偿。
对于第二种情况，第二芯片确定所述位置信息在所述视频图像信号中对应的第一区域；所述第二芯片确定所述视频图像信号中第一区域之外的第二区域；第二芯片判断视频层信号的分辨率与所述显示屏的分辨率是否一致；如果不一致，根据所述显示屏的分辨率与视频层信号的分辨率之间的对应关系，则对所述第二区域进行缩放处理。
下面结合具体实例对第二区域的缩放过程作以详细的说明。在一实施例中第二芯片与4K显示屏相连接。对于一网络视频信号而言，第一芯片图形层信号的画面的尺寸信息为(w，h)，位置坐标信息(m，n)，第一芯片生成的位置信息为(m，n，w，h)；第一芯片发送(m，n，w，h)至第二芯片；第二芯片确定在所述位置信息在视频图像信号中对应的第一区域；确定所述视频图像信号中除第一区域之外的第二区域；第二芯片计算出显示屏分辨率与视频信号分辨率之间的对应关系为2倍；第二芯片对第二区域放大2倍处理。在一些实施例中缩放过程可以参阅图11以及图12，其中图11中，区域1为放大处理前的第一区域，区域2为放大处理前的第二区域，图12中区域3为放大处理后的第二区域。
最后，第二芯片对放大处理后的第二区域对应的图像进行运动补偿。
采用本申请实施例示出的技术方案可避免由于视频层信号的分辨率与所述显示屏的分辨率不一致造成动补偿区域计算结果不准确问题的出现。
S106：第二芯片将运动补偿后的第二区域的图像和第一区域的图像进行拼接以生成运动补偿后的图像。
将计算得到的补偿帧与OSD层对应区域混合得到运动补偿后的图像，然后，在当前帧视频画面与上一帧(或下一帧)视频画面之间插入该混合后补偿帧。进而，可以在解决中OSD层信号被运动补偿处理技术撕裂的同时，还能更好的通过运动补偿技术解决视频信号的卡顿与抖动问题。
S107：所述第二芯片将运动补偿后的图像输出到所述显示屏进行显示。
在一些实施例中，删除步骤可以不依照上述罗列的次序进行，只需能够根据图形层进行第二芯片的的运动补偿处理的控制即可。
在一些实施例中，显示设备可以不进行透明层的检测，直接进行图形层位置的判断，并根据图形层的位置控制运动补偿的区域。
在一些实施例中，显示设备可以先进行图形层位置的判断，在图形层位置覆盖的区域小于第一预设值的时候根据图形层的位置控制运动补偿的区域，在图形层位置覆盖的区域大于第二预设值的时候再进行透明层的检测，是透明层，则整帧进行运动补偿处理，不是，则不进行运动补偿处理。
在一些实施例中，先进行透明层的判断，是透明层，则整帧进行运动补偿处理，不是，则检测图形层的位置，然后在位置对应的区域不进行运动补偿，位置对应的区域外进行运动补偿。
在一些实施例中，针对第三方应用所创建的透明的图形层通常是一个全屏的透明图形层，因此，为了减少对图像层进行像素分析的数据处理量，本申请一些实施例还提供了另一种图 像处理方法，应用于显示设备中，该显示设备包括第一芯片、第二芯片和显示屏。图13中示例性示出了另一种图像处理方法的流程示意图。如图13所示，该方法主要包括如下步骤：

S203：响应于所述相对面积大于预设面积值，则检测所述图形层信号对应的图形层是否为透明层。
