发送端100包括图像信号处理器(ISP)110、编码器120、发射器130,存储器140、发射天线150和视觉传感器160。
ISP110与视觉传感器160相连接,ISP110例如可以通过移动工业处理器接口(Mobile Industry Processor Interface,MIPI)与视觉传感器160相连接。ISP110用于从视觉传感器160接收图像数据,例如,图像帧的像素,并对图像帧的像素进行预处理,例如,对图像帧的像素进行线性纠正、噪声去除、坏点去除、内插、白平衡、自动曝光控制等处理。ISP160还用于以分片(slice)为单位传输图像帧的像素。例如,如图1所示,ISP110可以通过ISP110与编码器120之间的通信接口直接传输分片。可替代地,ISP110也可以将分
片写入存储器140,以便编码器120从存储器140读取分片。ISP110也可以称为图像信号处理单元或图像信号处理装置。ISP110例如可以由片上系统(system on a chip)来实现。
在本发明的实施例中,图像帧的分片是指图像帧的一部分,即分片所包含的像素数小于图像帧所包含的像素数,分片可以包括图像素帧的至少一行像素或至少一列像素,例如,16行像素或者16列像素。
编码器120用于以分片为单位对经过ISP处理的像素进行编码处理,并以分片为单位传输经过编码处理后的图像帧的像素。例如,编码器120可以将经过编码处理的分片发送到存储器140,以便发射器130从存储器140读取经过编码处理的分片。作为替代,编码器120也可以直接向发射器130传输经过编码处理的分片。编码器120也可以称为编码单元或编码装置。

视觉传感器160可以是任何类型的用于捕获图像数据的视觉传感器,例如,照相机、摄像机或者其它包括照相机或摄像机的设备上的互补金属氧化物半导体(Complementary Metal Oxide Semiconductor,CMOS)传感器。
应理解,虽然图1以ISP110和视觉传感器110直接传输分片为例进行说明,但本发明的实施例并不限于此,例如,ISP110也可以通过存储器140向编码器120传输分片。虽然图1以编码器120和发射器130通过存储器140传感分片为例进行说明,但本发明的实施例并不限于此,例如,编码器120也可以直接向发射器130传输分片。
还应理解,虽然图1的实施例以图像信号处理器和编码器为独立实体为例进行说明,但本发明的实施例并不限于此,例如,编码功能和图像信号处理功能也可设置在一个实体中,例如,设置在图像处理器中。
图2是根据本发明的一个实施例的视频传输的接收端200的结构示意图。
接收端200包括显示控制器210、译码器220、接收器230,存储器240、
接收天线250和显示器260。

译码器220用于以分片为单位对从接收器230接收到的图像帧的像素进行译码处理,并以分片为单位将经过译码处理后的图像帧的像素发送给显示控制器210。例如,如图2所示,译码器220可以直接向显示控制器210传输分片。作为替代,译码器220也可以将分片缓存在存储器240中,以便显示控制器210从存储器240中读取分片。
显示控制器210用于以分片为单位从译码器220接收经过译码处理的图像帧的像素,并通过显示器260显示图像帧的像素。
存储器240用于缓存经过上述模块处理后的图像帧的像素。存储器240例如可以是动态随机存取存储器(Dynamic Random Access Memory,DRAM),存储器240可以设置为一个实体,也可以设置为分布于上述不同模块之间的多个实体。

还应理解,虽然图2的实施例以译码器和显示控制器为独立实体为例进行说明,但本发明的实施例并不限于此,例如,译码功能和显示控制功能也可设置在一个实体中,例如,设置在图像处理装置中。
下面结合图3至图5的实施例对发送端的实体所执行的方法进行详细的描述。
图3是根据本发明一个实施例的图像信号处理方法的示意性流程图。图3的实施例可以由图1的图像信号处理装置、图像信号处理器或图像处理单元来执行。以下以图像信号处理装置为例进行说明。图3的图像信号处理方法包括如下内容。
310,获取由视觉传感器捕获的图像帧的分片中的像素,其中分片包含
的像素为图像帧包含的未处理的像素中的一部分。
例如,图像帧可以包括多个具有相同数量的像素的分片,但本发明的实施例并不限于此,图像帧也可以包括多个具有不同数量的像素的分片,例如,可以预先设置同一个像素中的不同分片具有不同数量的像素。可选地,作为另一实施例,也可以设置不同业务类型的分片具有不同数量的像素。
例如,分片可以包括以下任意一项:图像帧中的预定数量的行的像素(例如,16行);图像帧中的预定数量的列的像素(例如,16列);图像帧中的预定数量的像素(例如,16行像素所包含的像素的数量或16列像素所包含的像素的数量)。
320,对分片中的像素进行处理。
例如,对图像帧的像素进行线性纠正、噪声去除、坏点去除、内插、白平衡、自动曝光控制等预处理。
330,响应于处理完分片中的像素,传输分片。
具体地,视觉传感器可以将捕获的图像帧的像素逐个或逐行传输给图像信号处理装置进行预处理。例如,可以通过确定处理过的像素的数目是否达到一个分片的大小来确定是否处理完一个分片的像素,每当处理完一个分片大小的像素时,图像信号处理装置开始传输该分片,同时图像信号处理装置继续处理其它未处理的像素,即下一分片的像素,并且一旦处理完下一分片的像素时,就开始传输下一分片的像素,以此类推。例如,可以预先设置分片的大小的阈值,例如,M行像素或者N个像素,M和N均为正整数。每当图像信号处理装置确定处理完16行像素或N个像素时,开始传输这M行或N个像素。
根据本发明的实施例,图像信号处理装置可以每当处理完图像帧的一个分片的像素时,就开始传输该分片的像素。由于本发明的实施例可以以分片为单位传输图像帧的像素,而无需等到处理完一个图像帧才开始传输该图像帧,因此减少了传输延时,提高了用户体验。
在330中,上述传输分片可以包括:将分片存储到存储空间,并指示编码装置从存储空间获取分片。
例如,存储空间可以为图1的实施例中的存储器中的一部分,也可以是一个独立的存储器。存储空间可以为以下任意一项:图像信号处理装置中的缓存;编码装置中的缓存;在图像信号处理装置和编码装置之间的缓存。
例如,每当处理完一个分片,并将该分片的像素存储到存储空间时,图像信号处理装置向编码装置发送指示信息,用于指示编码装置从存储空间获取该分片。编码装置在接收到该指示信息后,确认存储空间已经存储了一个分片的像素,并从存储空间读取该分片的像素。该指示信息可以包括第一存储空间的地址信息,例如,具体的存储地址或存储地址的索引。指示信息也可以不携带该地址信息,而是在编码装置和图像信号处理装置两侧预先约定或设置该存储地址。
根据本发明的实施例,通过设置存储空间来存取分片,使得分别属于不同厂商或者具有不同性能(例如,传输速率)的图像信号处理装置和编码装置之间可以实现分片的传输。
可替代,作为另一实施例,图像信号处理装置也可以直接向编码装置发送该分片。例如,可以设计能够直接通信且性能匹配的图像信号处理装置和编码装置,使得每当处理完一个分片时,图像信号处理装置可以通过图像信号处理装置与编码装置之间的通信接口直接向编码装置发送该分片。
根据本发明的实施例,由于图像信号处理装置直接将处理完的分片的像素发送给编码装置,进一步减少了传输延时,并且节省了存储空间。
图4是根据本发明一个实施例的图像编码方法的示意性流程图。图4的实施例可以由图1的编码装置、编码器或编码单元来执行。以下以编码装置为例进行说明。图4的图像编码方法对应于图3的图像信号处理方法,在此适当省略详细的描述。图4的图像编码方法包括如下内容。

应理解,图像信号处理装置可以以分片为单位向编码装置发送图像帧的像素,本发明的实施例并不限于此,图像信号处理装置也可以按常规的方式向编码装置发送图像帧,而由编码装置以分片为单位进行编码。
例如,分片可以包括以下任意一项:图像帧中的预定数量的行的像素(例
如,16行);图像帧中的预定数量的列的像素(例如,16列);图像帧中的预定数量的像素(例如,16行像素所包含的像素的数量或16列像素所包含的像素的数量)。
420,对分片进行编码。响应于接收到一个分片,对分片进行编码。
例如,可以通过确定接收到的像素的数目是否达到一个分片的大小来确定是否接收到一个分片的像素,并且每当确定接收到一个分片的像素时,对分片进行编码。本发明的实施例对编码的方式不作限定,可以是视频或图像编码技术中使用的任意编码方式。
430,响应于编码完分片中的像素,传输分片。
具体地,编码装置可以获取图像信号处理装置传输的图像帧的一个分片的像素,并且可以通过确定编码完的像素的数目是否达到一个分片的大小来确定是否编码完一个分片的像素,每当接收到一个分片的像素时,对该分片的像素进行编码,每当编码完一个分片大小的像素时,编码装置开始传输该分片,同时编码装置继续编码接下来的像素,即下一分片的像素,并且一旦编码完下一分片的像素时,就开始传输下一分片的像素,以此类推。例如,可以预先设置分片的大小的阈值,例如,M行或列像素或者N个像素,M和N均为正整数。每当编码装置确定编码完M行或列像素或N个像素时,开始传输这M行或列像素或N个像素。
根据本发明的实施例,编码装置可以每当接收到一个分片的像素时,就开始编码该分片的像素,并且每当编码完图像帧的一个分片的像素时,就开始传输该分片的像素。由于本发明的实施例可以以分片为单位传输图像帧的像素,而无需等到编码完一个图像帧才开始传输该图像帧,从而减少了传输延时,提高了用户体验。

例如,第二存储空间可以为图1的实施例中的存储器中的一部分,也可以是一个独立的存储器。第二存储空间为以下任意一项:编码装置中的缓存;发射器中的缓存;在编码装置和发射器之间的缓存。
例如,编码装置在将一个分片的像素存储到第二存储空间后,向发射器发送指示信息,用于指示发射器从第二存储空间获取该分片。发射器在接收到该指示信息后,确定第二存储空间已经存储了一个分片的像素,并从第二存储空间读取该分片的像素。该指示信息可以包括第二存储空间的地址信息,例如,具体的存储地址或存储地址的索引。作为替代,指示信息也可以不携带该地址信息,而是在编码装置和发射器两侧预先约定或设置该存储地址。
根据本发明的实施例,通过设置存储空间来存取分片,使得分别属于不同厂商或者具有不同性能(例如,传输速率)的编码装置和发射器之间可以实现分片的传输。
可替代,作为另一实施例,编码装置也可以直接向发射器发送该分片。例如,可以设计能够直接通信且性能匹配的编码装置和发射器,使得每当处理完一个分片时,编码装置可以通过编码装置与发射器之间的通信接口直接向发射器发送该分片。
