Description

一种终端显示防抖方法及装置 技术领域
本发明涉及图像稳定技术领域,尤其涉及一种终端显示防抖方法及装置。
背景技术
在终端播放视频的情况下,若终端存在抖动(例如,使用该终端的用户乘坐交通工具时),则会影响使用该终端的用户观看视频的稳定性。目前,为了提高终端存在抖动的情况下用户观看视频的稳定性,终端利用内置的运动传感器获取该终端的运动量,根据获取到的终端的运动量确定终端的位移补偿量,并根据该位移补偿量对该终端的屏幕中显示的图像进行补偿(例如,若获取到终端向左移动一毫米,则将终端的屏幕中显示的图像向右移动一毫米),从而尽量减少终端的屏幕中显示的图像的运动量,提高用户观看视频的稳定性。
这种方法的缺点是,终端的屏幕显示的图像根据终端的运动量进行补偿时,会使得屏幕显示的图像出现黑边,即屏幕的某一边的一部分区域中无显示图像,另一边显示的图像超出屏幕边界的情况(例如,将终端的屏幕显示的图像向右移动5个像素,屏幕左边将出现5个像素的空白)。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
如图1所示,为一种终端的组成示意图,本发明实施例提供的方法可以应用于该终端中。其中,终端包括硬件和软件部分,软件部分具体包括操作系统、中间件、显示防抖模块以及应用程序等,操作系统具体包括传感器数据处理模块和Framebuffer等,硬件部分具体包括中央处理器(Central Processing Unit,简称CPU)、图形处理器(Graphics Processing Unit,简称GPU)、显示器、内存以及传感器等。目前对终端显示的内容进行防抖的方法包括:传感器获取终端的运动数据,并将运动数据传递给传感器数据处理模块,传感器数据处理模块对运动数据进行处理后,将处理后的运动数据传递给显示防抖模块,显示防抖模块采用显示防抖算法对经传感器数据处理模块处理后的运动数据进行计算,确定终端显示的内容的补偿量,Framebuffer根据补偿量将内存中的图像数据显示在显示器中。
本发明实施例提供了一种终端显示防抖方法,所述终端包括随机存取存储器(Random-Access Memory,简称RAM)和显示器,所述RAM包括显示内存缓冲区,所述显示内存缓冲区用于存储缓存图像,所述缓存图像的水平方向的像素数大于所述显示器的水平方向 的像素数,所述缓存图像的垂直方向的像素数大于所述显示器的垂直方向的像素数,所述显示器中的当前显示图像为所述缓存图像中的一部分,如图2所示,该方法包括:
201、所述终端获取所述终端与使用所述终端的用户的眼睛的相对运动量。
其中,本发明实施例中的终端可以为手机、虚拟现实(Virtual Reality,简称VR)设备、增强现实(Augmented Reality,AR)设备、平板电脑、智能手表、投影设备以及其他用户在观看图像时设备和人眼可能发送抖动的显示设备。
本发明实施例中终端的显示器中显示的图像可以为视频图像、游戏画面以及网页内容等,本发明实施例对此不进行限制。
本发明实施例提供的方法在具体实现时,终端执行步骤201的触发条件可以为终端的屏幕被点亮。
其中,显示内存缓冲区用于缓存一帧完整图像的数据(具体包括图像中的每个像素点的位置及灰度值等),终端在显示图像时,该图像已经在显示内存缓冲区中绘制完毕,显示内存缓冲区中的数据可以通过Framebuffer进行管理。
本发明实施例中,缓存图像的水平方向的像素数和垂直方向的像素数可以根据终端的显示器的水平方向的像素数和垂直方向的像素数进行确定,缓存图像的水平方向的像素数和垂直方向的像素数分别大于显示器的水平方向的像素数和垂直方向的像素数。
示例性的,如图3所示,区域1代表终端的显示器,其水平方向的像素数为X1,垂直方向的像素数为Y1,区域2代表缓存图像,其水平方向的像素数为X2,垂直方向的像素数为Y2,其中,X2大于X1,Y2大于Y1
可选的,所述相对运动量包括相对位移运动量和/或相对角度运动量。
该情况下,既可以对显示器中显示的图像进行位移补偿,也可以对显示器中显示的图像进行角度补偿。
可选的,步骤201在具体实现时,包括:所述终端采用虹膜技术或巩膜技术检测所述用户的眼睛相对于所述终端的运动,并获取所述用户的眼睛相对于所述终端的相对运动量。
具体的,终端可以采用终端的前置摄像头获取多帧前景图像,并通过虹膜技术(或巩膜技术)识别前景图像中的虹膜(或巩膜),根据多帧前景图像中的虹膜(或巩膜)的位置及转动角度等确定用户的眼睛相对于终端的相对运动量。
由于虹膜技术或巩膜技术相比人脸识别技术而言,识别精度较高,因此,可以提高确定的相对运动量的精度。
另外,终端还可以基于深度传感器的技术(例如结构光、激光传感器等)对用户的眼睛进行三维建模,通过用户的眼睛运动的信息、用户的眼睛和终端的距离信息以及用户的两眼的距离等信息,精确计算相对运动量。
202、所述终端根据所述当前显示图像与所述缓存图像的位置关系和所述相对运动量在所述缓存图像中获取待显示图像,所述待显示图像为对所述相对运动量进行补偿后,所述显示器中即将显示的图像,所述待显示图像的水平方向的像素数与所述显示器的水平方向的像素数相同,所述待显示图像的垂直方向的像素数与所述显示器的垂直方向的像素数相同。
需要说明的是,当终端获取到相对运动量时,由于终端显示于显示器的图像在显示到显示器前,已经在显示内存缓冲区中绘制完 毕,因此,终端可以快速的确定待显示图像,并快速的显示待显示图像。
具体的,当相对位移量为不同的运动量时,步骤202的执行方式也不相同,以下以五种情况为例分别介绍步骤202的实现方式:
方式一:当所述相对运动量为所述用户的眼睛相对于所述终端的位移运动量、且所述用户的眼睛相对于终端的位移运动量为沿着x轴方向的位移运动量或沿着y轴方向的位移运动量时,所述终端将所述缓存图像中的与所述当前显示图像中的N个像素点一一对应的N个像素点组成的图像确定为所述待显示图像,其中,所述待显示图像中的任意一个像素点在所述缓存图像中的坐标值比所述当前显示图像中的与该像素点对应的像素点在所述缓存图像中的坐标值大目标值,所述目标值为所述用户的眼睛相对于所述终端的位移运动量的值,N为正整数。
其中,x-y垂直坐标系所在的平面与显示器所在平面为同一平面或平行的平面。
方式一在具体实现时,可以将当前显示图像中的一个像素点作为第一基准像素点,将第一基准像素点的坐标增加目标值得到第二基准像素点,然后根据第一基准像素点在当前显示图像中的位置,以第二基准像素点作为基准在缓存图像中获取待显示图像,第二基准像素点在待显示图像中的位置与第一基准像素点在当前显示图像中的位置相同。
示例性的,基于图3所述的示例,参见图4-a,A为第一基准像素点,其在缓存图像中的坐标值为(x,y),若位移运动量的值为[w1,0],则将第一基准像素点增加[w1,0],得到第二基准像素点A′,参见图4-b,A′在缓存图像中的坐标值为(x+w1,y),若A为当前显示图像中的水平方向的第一个像素点、且为垂直方向的第一个像素 点,则终端可以以A′为基准,确定水平方向的X1个像素点、垂直方向的Y1个像素点所组成的图像为待显示图像,在该示例中,当前显示图像即图4-a中的区域1中的图像,待显示图像即图4-b中的区域1中的图像,该示例中的w1为正值。
需要说明的是,本发明实施例中的目标值可以通过[w1,w2]表示,其中,w1和w2分别表示沿x轴和y轴的相对位移运动量,w1和w2均可以通过携带的正负号区分相对位移运动量的方向(沿着相应轴线的正方向还是反方向)。当然,该种表示目标值的方法中的各个值之间也可以为其他顺序,本发明实施例对此不做具体限定。本发明实施例中也只是举例说明了一种目标值的表示方法,实际上也可以采用其他方法进行表示。
方式二:当所述相对运动量为所述用户的眼睛相对于所述终端的位移运动量、且所述用户的眼睛相对于所述终端的位移运动量为沿着z轴方向的位移运动量时,所述终端根据所述当前显示图像与所述缓存图像的位置关系和所述相对运动量确定第一图像,所述终端对所述第一图像进行处理得到第二图像并确定所述第二图像为所述待显示图像。
其中,当所述相对运动量的值表示所述用户的眼睛远离所述终端时,所述第一图像为所述当前显示图像中心部分的图像,所述终端对所述第一图像进行处理为所述终端放大所述第一图像;或者,当所述相对运动量的值表示所述用户的眼睛靠近所述终端时,所述当前显示图像为所述第一图像中心部分的图像,所述终端对所述第一图像进行处理为所述终端缩小所述第一图像。
方式二在具体实现时,可以先根据相对运动量换算一个水平方向的像素数k1和垂直方向的像素数k2,相对运动量越大时,k1和k2也越大,k1和k2的比值与当前显示图像中的水平方向的像素数和垂 直方向的像素数的比值相同,以当前显示图像为基准,在缓存图像中获取比当前显示图像左右方向各多k1个像素数、上下方向各多k2个像素数的图像作为第一图像,然后将第一图像缩小至第二图像,第二图像的水平方向的像素数和垂直方向的像素数分别与显示器的水平方向的像素数和垂直方向的像素数相同。
示例性的,如图5所示,当k1=2,k2=3时,确定的第一图像与当前显示图像的位置关系可参见图5。
其中,根据相对运动量换算k1和k2的方法可以为:确定一个预设值,该预设值对应一个水平方向的像素点,k1等于相对运动量除以该预设值的结果取整后的值,k2根据k2与k1的比值确定。
方式三:当所述相对运动量为所述用户的眼睛相对于所述终端的角度运动量时,所述终端将所述当前显示图像旋转目标角度后得到的图像确定为所述待显示图像,所述目标角度为所述用户的眼睛相对于所述终端的角度运动量的值。
可选的,所述相对角度运动量包括所述用户的眼睛相对于所述终端在三维方向上的角度运动量。
示例性的,基于图3所述的示例,图6-a中的区域1中的图像为当前显示图像,当终端获取到的角度运动量为用户的眼睛相对于终端绕着z轴逆时针旋转了s1°时,终端可以将当前显示图像绕着z轴逆时针旋转s1°进行显示,显示器中显示的图像如图6-b所示。
另外,终端获取到的相对角度运动量也可以为用户的眼睛相对于终端绕着x轴和y轴旋转的角度。示例性的,图7-a、图7-b和图7-c分别示出了当前显示图像绕着z轴、y轴和x轴旋转后显示器中显示的图像,其中,图7-a、图7-b和图7-c中,显示器中显示的图像为当前显示图像与旋转后的当前显示图像的公共部分。
需要说明的是,本发明实施例中的目标角度可以通过[s1,s2,s3]表示,其中,s1、s2和s3分别表示绕着x轴、绕着y轴和绕着z轴的相对角度运动量,s1、s2和s3均可以通过携带的正负号区分相对角度运动量的方向(绕着相应轴线的顺时针还是逆时针)。当然,该种表示目标角度的方法中的各个值之间也可以为其他顺序,本发明实施例对此不做具体限定。本发明实施例中也只是举例说明了一种目标角度的表示方法,实际上也可以采用其他方法进行表示。
方式四:当所述相对运动量为所述用户的眼睛相对于所述终端的位移运动量和所述用户的眼睛相对于所述终端的角度运动量、且所述用户的眼睛相对于所述终端的位移运动量为沿着z轴方向的位移运动量时,所述终端根据所述当前显示图像与所述缓存图像的位置关系和所述相对运动量确定第一图像,所述终端对所述第一图像进行处理得到第二图像,所述终端将所述第二图像旋转目标角度后得到的图像确定为所述待显示图像,所述目标角度为所述用户的眼睛相对于所述终端的角度运动量的值。
其中,确定第二图像的过程可以参见方式二,旋转第二图像的方法可以参见方式三,在此不再赘述。
方式五:当所述相对运动量为所述用户的眼睛相对于所述终端的位移运动量和所述用户的眼睛相对于所述终端的角度运动量、且所述用户的眼睛相对于终端的位移运动量为沿着x轴方向的位移运动量或沿着y轴方向的位移运动量时,所述终端将所述缓存图像中的与所述当前显示图像中的N个像素点一一对应的N个像素点组成的图像确定为中间图像,所述终端将所述中间图像旋转目标角度后得到的图像确定为所述待显示图像,其中,所述中间图像中的任意一个像素点在所述缓存图像中的坐标值比所述当前显示图像中的与该像素点对应的像素点在所述缓存图像中的坐标值大目标值,所述 目标值为所述用户的眼睛相对于所述终端的位移运动量的值,所述目标角度为所述用户的眼睛相对于所述终端的角度运动量的值,N为正整数。
其中,确定中间图像的过程可以采用方式一中的确定待显示图像的方法进行确定,旋转中间图像的方法可以参见方式三,在此不再赘述。
在本发明实施例中,当相对运动量包括多个维度上的位移运动量时,可以依次根据多个维度上的位移运动量确定待显示图像,当相对运动量包括多个维度上的角度运动量时同理。
203、所述终端将所述待显示图像显示在所述显示器中。
本发明实施例提供的方法可以应用在多种生活场景中,示例性的,在用户乘坐地铁(或公交车)的应用场景下,若用户正在浏览图片,由于地铁(或公交车)的晃动,会导致用户的眼睛和该用户的终端之间产生相对运动,从而使得用户无法稳定的浏览图片,该情况下,终端可以获取相对运动量,并确定待显示图像后在显示器中进行显示。
本发明实施例提供的方法,终端获取到终端与使用终端的用户的眼睛的相对运动量之后,可以根据当前显示图像与缓存图像的位置关系和相对运动量在缓存图像中获取对该相对运动量进行补偿后的待显示图像,由于缓存图像的水平方向的像素数大于显示器的水平方向的像素数,缓存图像的垂直方向的像素数大于显示器的垂直方向的像素数,从而使得待显示图像的水平方向的像素数可以与显示器的水平方向的像素数相同,待显示图像的垂直方向的像素数可以与显示器的垂直方向的像素数相同,因此,显示器在显示待显示图像时,显示器中不会出现黑边。
