Description

一种虚拟现实显示设备及显示方法 技术领域
本发明涉及显示技术领域，尤其涉及一种虚拟现实显示设备及显示方法。
背景技术
虚拟现实(Virtual Reality，VR)技术是近年来出现的高新技术，其利用计算机硬件、软件和传感器等，建立虚拟现实环境，使用户能够通过VR设备体验虚拟世界并与虚拟世界交互。
现主流VR设备的单眼分辨率为1080*1200。单眼4320*4320或者更高分辨率VR设备，是目前市面上还未出现的参数。智能显示(smartview)技术的引入一定程度上解决了单眼高分辨率图像在硬件传输和软件渲染方面的瓶颈。结合人眼跟踪(eyetracking)算法，既保证了注视区域的分辨率需求，又降低了渲染压力和传输带宽。
但现有技术的虚拟现实显示设备在进行smartview时，存在功耗较高，资源浪费问题。
发明内容
本发明提供一种虚拟现实显示设备及显示方法，以改善现有技术的虚拟现实显示设备，存在功耗较高，资源浪费的问题。
本发明实施例提供一种虚拟现实显示设备的显示方法，包括：
响应于用户的第一操作，启用智能显示模式；
控制所述虚拟现实显示设备的屏幕在人眼注视的第一显示区以第一清晰度显示，以及控制所述第一显示区以外的第二显示区以第二清晰度显示，其中，所述第一清晰度高于所述第二清晰度；
控制所述第二显示区的部分像素进行补黑显示。
在一种可能的实施方式中，所述控制所述第二显示区的部分像素进行补 黑显示，包括：
控制所述第二显示区的补黑像素形成多个依次嵌套的第一闭合图案，未补黑像素形成多个依次嵌套的第二闭合图案，所述第一闭合图案和所述第二闭合图案相间排列。
在一种可能的实施方式中，所述第一闭合图案、所述第二闭合图案的形状与所述第一显示区的形状相似。
在一种可能的实施方式中，所述控制所述第二显示区的部分像素进行补黑显示，包括：
控制所述第二显示区的补黑像素形成多个沿第一方向延伸的第一像素组，未补黑像素形成多个沿所述第一方向延伸的第二像素组，所述第一像素组和所述第二像素组相间排列。
在一种可能的实施方式中，所述第一方向为像素行方向或像素列方向。
在一种可能的实施方式中，所述控制所述虚拟现实显示设备在人眼注视的第一显示区以第一清晰度显示，以及控制所述第一显示区以外的第二区域以第二清晰度显示，包括：
将接收的用于在所述第二显示区显示的第二图像拉伸成与所述虚拟现实显示设备的屏幕分辨率相同的图像，并进行全屏显示；
将接收的用于在所述第一显示区显示的第一图像以原分辨率覆盖于所述第一显示区进行显示。
在一种可能的实施方式中，所述显示方法还包括：
响应于用户的第二操作，启用真实显示模式；
将接收到的与所述虚拟现实显示设备的屏幕分辨率相同的第三图像以原分辨率进行全屏显示。
在一种可能的实施方式中，在响应于用户的第一操作，启用智能显示模式之前，所述显示方法还包括：实时监测用户操作。
在一种可能的实施方式中，在响应于用户的第一操作，启用智能显示模式之后，以及在控制所述虚拟现实显示设备的屏幕在人眼注视的第一显示区 以第一清晰度显示，以及控制所述第一显示区以外的第二显示区以第二清晰度显示之前，所述显示方法还包括：
获取人眼注视区域；
对与所述人眼注视区对应的原始第一图像进行渲染，以及与所述人眼注视区以外的其它区域对应的原始第二图像进行渲染；
对所述原始第一图像进行图像算法处理，生成第一图像，并对所述原始第二图像进行图像算法处理，生成第二图像。
本发明实施例还提供一种虚拟现实显示设备，包括处理部件，所述处理部件用于执行如本发明实施例提供的所述显示方法。
本发明实施例有益效果如下：本发明实施例提供的所述虚拟现实显示方法，包括：响应于用户的第一操作，启用智能显示模式；控制所述虚拟现实显示设备的屏幕在人眼注视的第一显示区以第一清晰度显示，以及控制所述第一显示区以外的第二显示区以第二清晰度显示，其中，所述第一清晰度高于所述第二清晰度；控制所述第二显示区的部分像素进行补黑显示，即，由于第二显示区为非人眼注视的区域，本身并不用于主要的观看显示，而其通过对第二显示区的部分像素进行补黑显示，可以在不影响人眼对第一显示区观看的同时，降低更加符合非人眼注视区低分辨率的特性，同时大大降低了非高清显示区域的功耗，进而避免非人眼注视区的第二显示区若要全部点亮所有像素，会造成虚拟现实显示设备功耗较高，资源浪费的问题。

为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知部件的详细说明。
参见图1，本发明实施例提供一种虚拟现实显示设备的显示方法，包括：
步骤S101、响应于用户的第一操作，启用智能显示模式。
步骤S102、控制虚拟现实显示设备的屏幕在人眼注视的第一显示区以第一清晰度显示，以及控制第一显示区以外的第二显示区以第二清晰度显示，其中，第一清晰度高于第二清晰度。具体的，可以使第一显示区以高清进行显示，使第二显示区以非高清进行显示。
步骤S103、控制第二显示区的部分像素进行补黑显示。具体的，可以通 过控制像素的灰阶为0，以实现使该像素进行补黑显示。
本发明实施例提供的虚拟现实显示方法，包括：响应于用户的第一操作，启用智能显示模式；控制虚拟现实显示设备的屏幕在人眼注视的第一显示区以第一清晰度显示，以及控制第一显示区以外的第二显示区以第二清晰度显示，其中，第一清晰度高于第二清晰度；控制第二显示区的部分像素进行补黑显示，即，由于第二显示区为非人眼注视的区域，本身并不用于主要的观看显示，而其通过对第二显示区的部分像素进行补黑显示，可以在不影响人眼对第一显示区观看的同时，降低更加符合非人眼注视区低分辨率的特性，同时大大降低了非高清显示区域的功耗，进而避免非人眼注视区的第二显示区若要全部点亮所有像素，会造成虚拟现实显示设备功耗较高，资源浪费的问题；同时，若虚拟现实显示的屏幕为液晶屏，本发明实施例中，由于第二显示区像素有时会补黑，液晶不需要时时翻转，可以增加液晶的显示寿命，提升液晶使用率。
具体的，关于第二显示区补黑像素和未补黑像素组成的图案，以下进行举例说明。
例如，结合图2所示，在具体实施时，关于步骤S103、控制第二显示区S2的部分像素进行补黑显示，包括：控制第二显示区S2的补黑像素形成多个依次嵌套的第一闭合图案A1，未补黑像素形成多个依次嵌套的第二闭合图案A2，第一闭合图案A1和第二闭合图案A2相间排列。具体的，第一闭合图案A1，第二闭合图案A2可以为框形，例如，第一闭合图案A1和第二闭合图案A2可以为矩形框，矩形框的每一边框由单行或单列像素组成。本发明实施例中，控制第二显示区S2的补黑像素形成多个依次嵌套的第一闭合图案A1，未补黑像素形成多个依次嵌套的第二闭合图案A2，第一闭合图案A1和第二闭合图案A2相间排列，可以使第二显示区不同位置的亮度基本一致，避免不同位置由于补黑的像素密度分布不同时，会造成不同位置亮度不一样的问题。
具体的，第一闭合图案A1、第二闭合图案A2的形状与第一显示区S1的形状相似。即，例如，第一显示区S1的形状为方形，则第一闭合图案A1和 第二闭合图案A2也为方形，又例如，若第一显示区S1的形状为圆形，则第一闭合图案A1和第二闭合图案A2也为圆形。
又例如，结合图3所示，控制第二显示区的部分像素进行补黑显示，包括：控制第二显示区S2的补黑像素形成多个沿第一方向延伸的第一像素组B1，未补黑像素形成多个沿第一方向延伸的第二像素组B2，第一像素组B1和第二像素组B2相间排列。可以理解的是，若第一方向经过第一显示区S1，则第一像素组B1包括的像素应为该方向上去除第一显示区S1以外的像素。本发明实施例中，制第二显示区S2的补黑像素形成多个沿第一方向延伸的第一像素组B1，未补黑像素形成多个沿第一方向延伸的第二像素组B2，第一像素组B1和第二像素组B2相间排列，可以在现有技术像素的显示方式上，进行较小的改进，补黑显示的方式较为简单，易于实现。
具体的，第一方向为像素行方向，参见图3所示；第一方向也可以为像素列方向，参见图4所示。
当然，在具体实施时，还可以是控制第二显示区的补黑像素和非补黑像素形成其它的图案，本发明不以此为限。
在具体实施时，关于步骤S102、控制虚拟现实显示设备在人眼注视的第一显示区以第一清晰度显示，以及控制第一显示区以外的第二区域以第二清晰度显示，包括：
步骤S1021、将接收的用于在第二显示区显示的第二图像拉伸成与虚拟现实显示设备的屏幕分辨率相同的图像，并进行全屏显示。即，第二显示区显示的图像为将接收到的图像进行拉伸后的图像。
步骤S1022、将接收的用于在第一显示区显示的第一图像以原分辨率覆盖于第一显示区进行显示。
在具体实施时，参见图5所示，显示方法还包括：
步骤S104、响应于用户的第二操作，启用真实显示模式(real显示模式)。
步骤S105、将接收到的与虚拟现实显示设备的屏幕分辨率相同的第三图像以原分辨率进行全屏显示。
本发明实施例中，显示方法还包括：响应于用户的第二操作，启用真实显示模式；将接收到的与虚拟现实显示设备的屏幕分辨率相同的第三图像以原分辨率进行全屏显示，进而可以使虚拟显示设备，同时可以根据需求智能的在smartview模式和real模式之间切换，丰富了整机的功能。
在具体实施时，结合图5所示，在步骤S101之前，即，在响应于用户的第一操作，启用智能显示模式之前，显示方法还包括：步骤S100、实时监测用户操作。
在具体实施时，在步骤S101之后，以及在步骤S102之前，即，在响应于用户的第一操作，启用智能显示模式之后，以及在控制虚拟现实显示设备的屏幕在人眼注视的第一显示区以第一清晰度显示，以及控制第一显示区以外的第二显示区以第二清晰度显示之前，显示方法还包括：
步骤S201、获取人眼注视区域。
步骤S202、对与人眼注视区对应的原始第一图像进行渲染，以及与人眼注视区以外的其它区域对应的原始第二图像进行渲染；
步骤S203、对原始第一图像进行图像算法处理，生成第一图像，并对原始第二图像进行图像算法处理，生成第二图像。
本发明实施例还提供一种虚拟现实显示设备，包括处理部件，处理部件用于执行如本发明实施例提供的显示方法。
为了更清楚地理解本发明实施例提供的虚拟现实显示设备的显示方法，以下结合图6进行具体说明：
本发明实施例中的虚拟现实显示设备具体可以包括：虚拟现实显示部件(例如，可以为虚拟显示头盔)和计算机设备，虚拟现实显示设备中的处理部件可以包括：虚拟现实显示部件中的第一处理部件，以及计算机设备中的第二处理部件。可以在虚拟现实显示设备设置两个按钮(可以是设置在虚拟现实显示部件的实体按钮，也可以是显示在计算机设备上的图标按钮，即，换成软件小程序来选择显示模式)，分别表示智能显示模式(smartview)和真实显示模式(real)，使用者使用前可根据需求选择想要体验的模式。
在进行显示时，可以执行如下几个步骤：
首先，软件端会持续监测是否有按钮按下，按下的是哪个显示模式，并且将选择的显示模式信息传递给软件和硬件；
其次，软件根据选择的显示模式输出图像，硬件根据选择的显示模式切换解析方案，具体如下：
对于smartview显示模式，对软件端，进行的步骤，可以包括：1、根据眼球追踪技术获得注视区域；2、渲染非高清图和眼睛注视区域的高清图，即，对与人眼注视区对应的原始第一图像进行渲染，以及与人眼注视区以外的其它区域对应的原始第二图像进行渲染；3、对高清图像和非高清图像做图像算法处理，常见的算法有图像增强、Local Dimming算法等，即，对原始第一图像进行图像算法处理，生成第一图像，并对原始第二图像进行图像算法处理，生成第二图像；4、将处理过的高清图(即，第一图像)和非高清图(第二图像)通过传输线传输给硬件端的虚拟现实显示部件；对于硬件端，执行的步骤包括：5、将接收的用于在第二显示区显示的第二图像拉伸成与虚拟现实显示设备的屏幕分辨率相同的图像，并进行全屏显示；6、非高清图像部分像素补黑，即，控制第二区域的部分像素进行补黑显示；7、将接收的用于在第一显示区显示的第一图像以原分辨率覆盖于第一显示区进行显示，即，将接收到高清和非高清图像后需要做一个拼接，拼接成一幅图像；8、Display显示拼接图像。
对于real显示模式，在软件端，具体可以与传统的VR显示方案一致，可以包括：1、渲染real分辨率图像；2、图像算法处理；3、将处理过的图通过传输线传输给硬件端的虚拟现实显示部件，在硬件端，进行相应显示。
需要说明的是，以上所描述的软件端，具体可以是存储在计算机设备存储部件的程序代码，对应的实现过程，可以是通过计算机设备的第二处理部件进行读取存储部件的程序代码进行执行实现。对于硬件端，具体可以是指虚拟现实显示部件上的第一处理部件，例如，IC。

显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
