立体片源的播放优化方法及装置
交叉引用
本申请引用于2015年12月28日递交的第201511014472.3号中国专利申请，其通过引用被全部并入本申请。
技术领域
本专利申请涉及多媒体技术领域，特别涉及一种立体片源的播放优化方法及装置。
背景技术
随着3D显示技术的发展，立体显示的应用也越来越广，而对于同一个立体片源，比如电影，在不同的显示设备上，立体显示效果不同。在观看过程中，影响立体效果的因素主要有立体影片的显示大小，即显示屏幕的大小，立体影片的视差等。
发明人在实现本发明的过程中发现，而对于立体影片，一般都是适应电影院观看的影片，当这些影片在其他设备上播放时，如虚拟现实Virtual Reality(VR)设备，整体的立体效果就会发生变化，也就是说，在电影院播放效果最好的立体影片，在VR设备上效果不一定最好，那么，为了有较好的立体效果，就需要对立体影片进行立体调整。而普通的调整方法是对影片给一个整体的参数，使整个播放过程中按照这个参数来进行播放，然而不同场景达到最优的立体效果，所需要的参数不同，若使用同一个参数对所有场景进行统一调整，势必会引起，一些场景看起来会比较好，但多数场景效果并不理想。
发明内容
本发明部分实施例的目的在于提供一种立体片源播放优化方法及装置，以立体片源的时间轴为主线，对各时间段画面所需达到的立体效果配置与其相适合的偏移调整量，保证在对立体片源在时间轴上进行视差调整过程中，各时间段所使用的立体参数均是匹配的，提高了立体片源的立体播放效果。
为解决上述技术问题，本发明的实施方式提供了一种立体片源播放优化方法，包含以下步骤：获取与立体片源的时间轴相关的立体调整参数；其中，立体调整参数包含T个偏移调整量和分别与T个偏移调整量相对应的时间段；T为自然数；在立体播放立体片源时，对处于各时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量。
本发明的一个实施例提供了一种计算机可读存储介质，包括计算机可执行指令，所述计算机可执行指令在由至少一个处理器执行时致使所述处理器执行上述方法。
本发明的实施方式还提供了一种立体片源播放装置，包含：
读取模块，用于从可读文件中读取与立体片源的时间轴相关的立体调整参数；其中，立体调整参数包含T个偏移调整量和分别与T个偏移调整量相对应的时间段；T为自然数；
播放模块，用于播放立体片源；其中，在立体播放立体片源时，对处于各时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量。
本发明实施方式相对于现有技术而言，将立体片源在其时间轴上划分为T个时间段，并对T个时间段分别配置有T个与之相对应的偏移调整量，此T个时间段及与之对应的T个偏移调整量即为立体片源的时间轴相关的立体调整参数；在立体播放立体片源时，对各时间段播放的画面均可通过所对应的偏移量调整，这样立体片源在整个时间轴上都可通过与之相匹配的调整参 数来调整画面，由于根据各时间段需要显示的不同的画面需要，有针对性的匹配了不同的立体调整参数，保证立体片源在各时间段的立体效果均达到最优，而且在不同的显示设备上都能达到很好的播放效果。从而达到优化整个立体片源立体播放的目的。
在一个实施例中，偏移调整量为带符号的数值；其中，不同符号表示左右视图的不同偏移方向。可通过符号表示左右视图的不同偏移方向，使得偏移调整参数的记录简洁清楚。而且，在对播放画面进行调整的过程中只需要根据偏移调整量符号就能判断该往哪个方向偏移，使得立体调整的过程变得更加方便快捷。
在一个实施例中，每个偏移调整量分别与立体片源中的一个连续镜头相对应。由于一个片源是由多个镜头组成的，一个连续的镜头对应相同的偏移调整量，保证了同一个镜头的画面具有相同的显示效果，提高了观看者的视觉体验。
在一个实施例中，获取与立体片源的时间轴相关的立体调整参数的步骤中，包含以下子步骤：将立体片源进行镜头的分解，得到组成该立体片源的各连续镜头分别对应的画面；在各连续镜头分别对应的画面中，选择T个需要调整的连续镜头的画面；对选择的连续镜头的画面，设置偏移调整量，并将该画面在时间轴内所处的时间段，作为与该偏移调整量相对应的时间段。通过将立体片源进行分解，可以将影片中特别的部分进行特殊的立体优化，使得画面调整的过程更加细致，从而使得立体片源在播放过程中，能够有针对性地调整特定镜头的画面播放效果。
在一个实施例中，在获取与立体片源的时间轴相关的立体调整参数的步骤中，获取的立体调整参数与预设类型的影片播放器相匹配；在立体播放立体片源时，对处于时间段的画面进行偏移量的调整的步骤中，包含以下子步骤：
判断播放立体片源的影片播放器是否为预设类型的影片播放器；
如果为预设类型的影片播放器，则预设类型的影片播放器对处于时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量；
如果不为预设类型的影片播放器，则对处于时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量和修正偏移量之和；其中，修正偏移量为预设类型的影片播放器与当前播放立体片源的影片播放器对相同画面相同效果的视图偏差量。通过修正偏移量可以校正当前播放器与预设播放器在播放相同画面相同效果的视图偏差量，解决当前影片播放器不是预设播放器时，因偏移调整量不同所带来的立体效果不理想的问题，即可使得同一个立体片源在不同的播放器上都能达到较好的立体播放效果。
在一个实施例中，预设不同影片播放器的偏移调整量的对应关系；根据对应关系获取修正偏移量，实现简单，有利于降低播放器的处理复杂度。
在一个实施例中，在立体播放所述立体片源的步骤中，还包含：接收预设按键的按压信号；根据接收到的按压信号生成用于对当前播放的画面进行调整的偏移调整量信号。在立体播放立体片源时，用户可以根据对立体画面的需要，在已有的立体效果的基础上，对立体效果再度调整，满足不同用户需要。

具体实施方式
为使本发明部分实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本发明各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本发明的第一实施方式涉及一种立体片源的播放优化方法，具体流程如图1所示。
在步骤101中，将立体片源在时间轴上进行镜头分解，得到组成该立体片源的各连续镜头分别对应的画面。在立体片源时间轴上对其进行镜头分解，为后续获取立体调整参数及对连续镜头对应的画面进行偏移量调整做准备。
接着，在步骤102中，选择需要调整的连续镜头的画面，生成立体调整参数。具体地说，在通过步骤101得到的各连续镜头分别对应的画面中，选择T个需要调整的连续镜头的画面，对需要调整的连续镜头对应的画面，设置偏移调整量，结合其在立体片源中所处的时间段，生成立体调整参数，并保存在可读文件中，以保证画面与立体调整参数的高度匹配，保证得到高质量的立体效果。
具体的说，立体调整方式一般是通过偏移立体图像的位置来实现的，当立体片源左视图与右视图正常完全重叠在屏幕2上时，得到的是平面效果， 左视图与右视图在屏幕上的相对位置关系如图2所示，图2中的标号1表示左视图与右视图完全重叠的画面，标号2表示屏幕。
当图像需要整体凸出显示时，左视图11向右平移N个像素，右视图12向左平移N个像素，左视图与右视图在屏幕2上显示的相对位置关系，如图3所示。
当图像整体需要凹进显示时，左视图11向左平移N个像素，右视图12向右平移N个像素，左视图与右视图在屏幕2上的相对位置关系，如图4所示。
通过以上偏移方法配置出立体片源各时间段内相应的偏移调整量，并保存为与立体片源时间轴相关的立体参数可读文件，该可读文件中时间段Ti的偏移调整量为Ni，偏移调整量Ni为带符号的数值，不同符号表示左右视图的不同偏移方向。比如说，Ni为正，代表左视图向左移动Ni，右视图向右移动Ni；Ni为负，代表左视图向右移动|Ni|，右视图向左移动|Ni|。偏移调整量Ni持续的时间为其对应的时间段Ti的起始时间到该时间段的结束时间，如Ti为1～1:30(即第1分钟到第1分30秒，左右视图的偏移调整量为Ni)。
也就是说，在本步骤中，最终得到可读文件中，将保存有若干(Ni，Ti)，每一个(Ni，Ti)对应一个连续镜头。
接着，在步骤103中，影片播放器从可读文件中读取立体调整参数，获取各偏移调整量所对应时间段的起始时间。
接着，在步骤104中，根据从可读文件中读取的立体调整参数，在立体片源播放过程中进行偏移量的调整。具体地说，影片播放器实时将当前播放时间与获得的起始时间对比，如果当前的播放时间与所述起始时间相同，则查找与该起始时间所在时间段相对应的偏移调整量，根据查找到的偏移调整量对当前播放的画面进行偏移量的调整，直至到达起始时间所在时间段的结束时间。
通过实时监控立体影片的播放时间段，查找当前时间段所对应的偏移调整量，并对该时间段内播放的画面进行视差调整，保证了立体调整参数与其同步。
不难发现，在本实施方式中，由于根据各时间段需要显示的不同的画面需要，有针对性的匹配了不同的立体调整参数，保证立体片源在各时间段的立体效果均达到最优，而且在不同的显示设备上都能达到很好的播放效果。从而达到优化整个立体片源立体播放的目的。而且，通过在各连续镜头分别对应的画面中，选择若干个需要调整的连续镜头的画面，对选择的连续镜头的画面，设置偏移调整量，可以将影片中特别的部分进行特殊的立体优化，从而使得立体片源在播放过程中，能够有针对性地调整特定镜头的画面播放效果。
本发明的第二实施方式涉及一种立体片源的播放优化方法。本实施方式在第一实施方式的基础上做了进一步改进，主要改进之处在于：在第二实施方式中，获取的立体调整参数与预设类型的影片播放器相匹配，即预先设置的立体调整参数是针对某一特定类型的影片播放器的，因此在播放影片时，需要判断实际播放影片的影片播放器是否为预设类型的影片播放器(即是否为与立体调整参数相匹配的影片播放器)。如果为预设类型的影片播放器，则对处于所述时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量(与第一实施方式的调整方式相同)；如果不为预设类型的影片播放器，则对处于所述时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量和修正偏移量之和。其中，修正偏移量为预设类型的影片播放器与当前播放立体片源的影片播放器对相同画面相同效果的视图偏差量。
通过修正偏移量对不同的影片播放器的偏移量进行修正，解决当前影片播放器不是预设播放器时，因偏移调整量不同所带来的立体效果不理想的问 题，即可使得同一个立体片源在不同的播放器上都能达到较好的立体播放效果。
本实施方式的具体流程如图5所示，步骤501至步骤503分别与第一实施例中相对应的步骤101至步骤103相同，在此不再赘述。
在步骤504中，判断播放立体片源的影片播放器类型是否为预设类型的影片播放器，即判断播放立体片源的影片播放器，是否为与立体调整参数相匹配的影片播放器。对影片播放器的类型进行判断，是为后续对图像进行偏移量调整做准备，为达到与预设影片播放器对相同画面达到相同的立体效果，需要根据播放器类型调用相对应的偏移调整量。
若判断结果为是，进入步骤507，根据从可读文件中读取的立体调整参数，在立体片源播放过程中进行偏移量的调整，本步骤与步骤104相同，在此不再赘述。
若判断结果为否，则进入步骤505，根据预设的不同影片播放器的偏移调整量的对应关系，获取相对应的修正偏移量。比如说，对于A类型的影片播放器而言，为达到特定的显示效果，需要将左右视图调整Ni的偏移量(Ni的符号为正)，然而，对于B类型的影片播放器而言，如果要达到相同的显示效果，则需要将左右视图调整N’i的偏移量。也就是说，A类型的影片播放器与B类型的影片播放器，对相同画面相同效果的视图偏差量(即修正偏移量)为|Ni-N’i|。
接着，进入步骤506，根据从可读文件中读取的立体调整参数和获取的修正偏移量，在立体片源的播放过程中进行偏移量的调整。通过对非预设类型的播放器进行调整偏移量的修正之后，可使得同一个立体片源在不同的播放器上都能达到较好的立体播放效果。
本发明的第三实施方式涉及一种立体片源的播放优化方法。第三实施方式在第一或第二实施方式的基础上做了进一步优化，主要改进之处在于：在 本发明第三实施方式中，增设一预设按键，按键可产生按压信号，播放器通过接收预设按键的按压信号生成用于对当前播放的画面进行调整的偏移调整量信号，从而完成对播放画面的调整。
比如说，用户可以定义电脑键盘的方向键“↑”为正向偏移调整，定义方向键“↓”为负向偏移调整，那么在电脑上播放立体片源的过程中，如果用户希望画面呈现更凹的效果，可以按压“↑”键来实现，同样如果用户希望呈现更凸的效果可以按压“↓”键来实现。
在立体播放过程中，按压按键，通过按压按键产生偏移调整量，即可在当前已有的立体效果基础上，对当前播放立体画面进行再次调整，更加贴合用户的视觉感受，提高用户体验。此外，本实施例中与第一实施例中相同的部分，第一实施例中的方法及步骤均适用于本实施例，在此不做赘述。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包含相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本发明第四实施方式涉及一种立体片源的播放装置，如图6所示，包含：
读取模块，用于从可读文件中读取与立体片源的时间轴相关的立体调整参数；其中，立体调整参数包含T个偏移调整量和分别与T个偏移调整量相对应的时间段；T为自然数。
播放模块，用于播放立体片源；其中，在立体播放立体片源时，对处于各时间段的画面进行偏移量的调整，调整的偏移量为与该时间段相对应的偏移调整量。
进一步地，每个偏移调整量分别与立体片源中的一个连续镜头相对应。
在本实施方式中，播放模块进一步包含：
获取子模块，用于获取各偏移调整量所对应的时间段的起始时间；
对比子模块，用于实时地将当前的播放时间与获取的起始时间进行对比；
查找子模块，用于在当前的播放时间与起始时间相同时，查找与该起始时间所在时间段相对应的偏移调整量；
调整子模块，用于根据查找到的偏移调整量对当前播放的画面进行偏移量的调整，直至到达起始时间所在时间段的结束时间。
不难发现，本实施方式为与第一实施方式相对应的装置实施例，本实施方式可与第一实施方式互相配合实施。第一实施方式中提到的相关技术细节在本实施方式中依然有效，为了减少重复，这里不再赘述。相应地，本实施方式中提到的相关技术细节也可应用在第一实施方式中。
值得一提的是，本实施方式中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单元的组合实现。此外，为了突出本发明的创新部分，本实施方式中并没有将与解决本发明所提出的技术问题关系不太密切的单元引入，但这并不表明本实施方式中不存在其它的单元。
结合本文中所揭示的实施例而描述的方法或算法的步骤可直接体现于硬件中，由处理器执行的软件模块中或所述两者的组合中。软件模块可驻留在随机存取存储器(RAM)、快闪存储器、只读存储器(ROM)、可编程只读存储器(PROM)，可擦除只读存储器(PROM)、可擦除可编程只读存储器(EPROM)、电可擦除可编程只读存储器(EEPROM)、寄存器、硬盘、可装卸式盘、压缩光盘只读存储器(CD-ROM)或此项技术中已知的任一其他形式的存储媒体。在替代方案中，存储媒体可与处理器成一体式。处理器及存储媒体可驻留在专用集成电路(ASIC)中。ASIC可驻留在计算装置或用户终端中，或者，处理器及存 储媒体可作为离散组件驻留在计算装置或用户终端中。
本领域的普通技术人员可以理解，上述各实施方式是实现本发明的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
