附图说明
通过结合附图进行的以下描述,本发明的实施例的上述和其它方面、特点和优点将变得更加清楚,附图中:
图1是根据本发明的实施例的改善显示画面中鬼影的方法的流程图;
图2是根据本发明的实施例的改善显示画面中鬼影的***的示意图。
具体实施方式
以下,将参照附图来详细描述本发明的实施例。然而,可以以许多不同的形式来实施本发明,并且本发明不应该被解释为限制于这里阐述的具体实施例。相反,提供这些实施例是为了解释本发明的原理及其实际应用,从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中,为了清楚起见,夸大了层和区域的厚度。相同的标号在整个说明书和附图中表示相同的元器件。
图1是根据本发明的实施例的改善显示画面中鬼影的方法的流程图。
参照图1,根据本发明的实施例的改善显示画面中鬼影的方法包括步骤110至步骤S160。
具体地,在步骤110中,获取显示装置将显示的画面的亮度和所述显示装置中鬼影的平均亮度。在本实施例中,显示装置包括液晶面板或者OLED显示面板以及其它的控制部件等。这里,需在暗态条件下对显示装置中鬼影的亮度进行检测,以获取所述鬼影的平均亮度。
在步骤120中,判断所述鬼影的平均亮度是否大于所述将显示的画面的亮度。如果是,则进行步骤130至步骤150。如果否,则进行步骤160。
在步骤130中,获取所述鬼影在所述显示装置中的位置。
进一步地,实现步骤130的方法具体包括:获取在显示装置中形成所述鬼影的对象与显示装置的相关数据;根据所述相关数据计算出所述鬼影在所述显示装置中的位置。在本实施例中,所述对象可例如是人脸,但本发明并不限制于此,例如,所述对象也可以是可投影在显示屏中影响阅读的其他影像。在这种情况下,所述相关数据至少包括:所述人脸与显示装置之间的距离、所述人脸中人眼活动的数据,但本发明并不限制于此,例如所述相关数据还包括其他影像相关参数。如此,可以利用显示装置上的摄像头定位人脸位置,并根据人脸与显示装置之间的距离以及人脸中人眼活动的数据等计算出鬼影在显示装置中的位置
此外,根据人脸与显示装置之间的距离以及人脸中人眼活动的数据计算出鬼影在显示装置中的位置的方法可以参照现有技术的相关方法,在此不再赘述。
在步骤140中,根据所述鬼影在所述显示装置中的位置以及所述鬼影的平均亮度对所述将显示的画面中与所述鬼影相对应的画面进行处理,以提高所述将显示的画面中与所述鬼影相对应的画面的亮度。这里,将提高亮度之后的所述将显示的画面中与所述鬼影相对应的画面与所述将显示的画面中与非所述鬼影相对应的画面作为实际显示的画面进行显示,由于所述将显示的画面中与所述鬼影相对应的画面的亮度被提高,从而其对比度被提高,进而增强了鬼影覆盖区域画面的可读性。
进一步地,实现步骤140的方法包括:利用下面的两个式子并根据所述鬼影在所述显示装置中的位置以及所述鬼影的平均亮度对所述将显示的画面中与所述鬼影相对应的画面进行处理。
Figure PCTCN2017110929-appb-000005
Figure PCTCN2017110929-appb-000006
其中,L′为实际显示的画面的像素的亮度,L0为所述将显示的画面的像素亮度,L1为显示装置的表面眩光亮度,k为显示画面时的周围环境光与显示画面的平均亮度的比值,a为判别系数,Vavg为所述显示装置中鬼影的平均亮度,Llow为所述将显示的画面中与所述鬼影相对应的画面的像素的最小亮度,Lhigh为所述将显示的画面中与所述鬼影相对应的画面的像素的最大亮度,gmax为最大增益值。
在步骤150中,对所述将显示的画面中与所述鬼影相对应的画面和所述将显示的画面中与非所述鬼影相对应的画面进行对比度平滑处理。需要说明的是,步骤150使所述将显示的画面中与所述鬼影相对应的画面和所述将显示的画面中与非所述鬼影相对应的画面的对比度平滑过渡,这是一种优选的实施方式,而作为本发明的另一实施方式,不进行对比度平滑处理也可以,也就是说,可以省略步骤150。
在步骤160中,不对将显示的画面进行任何处理,直接输出将显示的画面作为实际显示的画面。
图2是根据本发明的实施例的改善显示画面中鬼影的***的示意图。
参照图2,根据本发明的实施例的改善显示画面中鬼影的***包括显示装置210和环境光亮度感测器220。在本实施例中,显示装置210可以包括液晶面板或者OLED显示面板以及其它的控制部件等。环境光亮度感测器220可以设置于显示装置210中,但本发明并不限制于此。此外,根据本发明的实施例的改善显示画面中鬼影的***还可以包括其他必要的控制部件等。
环境光亮度感测器220用于获取所述显示装置210中鬼影的平均亮度,所述显示装置210用于获取将显示的画面的亮度。环境光亮度感测器220需在暗态条件下对显示装置中鬼影的亮度进行检测,以获取所述鬼影的平均亮度。
如果所述鬼影的平均亮度大于所述将显示的画面的亮度,则显示装置210还用于获取所述鬼影在所述显示装置210中的位置。
显示装置210还用于根据所述鬼影在所述显示装置210中的位置以及所述鬼影的平均亮度对所述将显示的画面中与所述鬼影相对应的画面进行处理,以提高所述将显示的画面中与所述鬼影相对应的画面的亮度。
此外,进一步地,显示装置210还用于对所述将显示的画面中与所述鬼影相对应的画面和所述将显示的画面中与非所述鬼影相对应的画面进行对比度平滑处理。
进一步地,显示装置210还用于获取在显示装置210中形成所述鬼影的对象与显示装置210的相关数据,并根据所述相关数据计算出所述鬼影在所述显示装置210中的位置。在本实施例中,所述对象可例如是人脸,但本发明并不限制于此,例如,所述对象也可以是可投影在显示屏中影响阅读的其他影像。在这种情况下,所述相关数据至少包括:所述人脸与显示装置之间的距离、所述人脸中人眼活动的数据,但本发明并不限制于此,例如所述相关数据还包括其他影像相关参数。如此,可以利用显示装置上的摄像头定位人脸位置,并根据人脸与显示装置之间的距离以及人脸中人眼活动的数据等计算出鬼影在显 示装置中的位置
此外,根据人脸与显示装置之间的距离以及人脸中人眼活动的数据计算出鬼影在显示装置中的位置的方法可以参照现有技术的相关方法,在此不再赘述。
显示装置210还用于利用上面的两个式子并根据所述鬼影在所述显示装置210中的位置以及所述鬼影的平均亮度对所述将显示的画面中与所述鬼影相对应的画面进行处理。
综上所述,根据本发明的实施例,利用软件算法的方式对显示画面中反射率和眩光较高的位置进行局部的亮度调节,从而提升显示装置的局部亮度,增强显示画面的可读性,实现抗眩抗反射的效果。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
