本发明的最佳实施方式
在具体实施方式中提及“实施例”意指结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的不同位置出现的相同用语并非必然被限制为相同的实施方式,而应当理解为与其它实施例互为独立的或备选的实施方式。在本发明提供的实施例所公开的技术方案启示下,本领域的普通技术人员应理解本发明所描述的实施例可具有其他符合本发明构思的技术方案结合或变化。
请参照图1至图3所示,为本发明具有屏幕内孔显示器影像处理方法的流程图与方块图。如图所示,本发明提供一种具有屏幕内孔显示器影像处理方法,包括以下步骤:步骤S10、确定所述内孔的中心坐标(i,j)和半径(r),并以所述半径划圆得到内孔区域的像素范围,并计算所述像素范围内的像素方差;步骤S20、分析所述内孔区域(Varea)和位于所述内孔区域的周边区域(Vsurr)的影像构成,判断所述内孔区域是否具有关键信息;步骤S30、定位所述内孔区域和所述周边区域的范围;及步骤S40、分别计算所述内孔区域和所述周边区域的像素均值和像素方差。
在步骤S40中,具体的计算方程式如下:
Figure PCTCN2019083416-appb-000005
其中,
Figure PCTCN2019083416-appb-000006
其中当所述内孔区域(Varea)大于所述周边区域与系数(k)的乘积(Vsurr*k)时,则认为所述内孔区域具有所述关键信息需要进行影像处理,反之,则维持原始影像。所述周边区域是指在内孔区域周边一定面积的影像区域,计算方式与上述方程式(Varea)相同。步骤S10中的像素方差实质上为步骤S40中的所述内孔区域的像素方差。
请一并参照图4所示,当所述内孔区域具有所述关键 信息需要进行影像处理时,所述影像处理还包括以下步骤:步骤S401、分析所述原始影像,对所述内孔区域的所述像素进行影像插值(image interpolation),使插值宽度等于所述内孔区域的直径;及步骤S402、对远离所述内孔区域的所述像素减去所述插值宽度,从而保持影像分辨率不变,其中采用帧间插值(interframe encoding)技术,确保影像能平滑过渡。
在步骤S401中,所述影像插值包含但不限于双线性插值(bilinear interpolation)或Lanczos插值,使影像信息更加完整,提升画面的和谐感。有关双线性插值或Lanczos插值为现有技术,在此不多加坠述。在步骤S402中,所述帧间插值技术能够有效防止影像处理造成的画面的突变,确保影像能平滑过渡。
在步骤S30中,定位所述内孔区域和所述周边区域的范围包含输入所述i,j,r,以确定所述所述内孔区域和所述周边区域的范围。在步骤S40中,将所述内孔区域和所述周边区域分别带入上述方程式中,以分别计算出所述像素均值和所述像素分差,所述方程式中的Mean表示所述像素均值,且所述系数(k)为大于1的合理数值,视需求而调整。
请一并参考图5A所示,当所述内孔区域和所述周边区域的影像信息一样时,通过所述方程式计算并判断所述 内孔区域不具有所述关键信息而维持所述原始影像。又如图5B及图5C所示,当所述内孔区域和所述周边区域的影像信息存在差异时,通过所述方程式计算并判断所述内孔区域具有所述关键信息而进行所述影像处理。
具体而言,由于所述内孔区域例如呈现一片大海,与所述周边区域的影像信息几乎一样,通过上述方程式计算得出不具有关键信息。因此不对如图5A所示的影像进行特殊处理,亦即维持原始影像。然而在如图5B及图5C中,由于所述内孔区域呈现的影像信息与所述周边区域的影像差别很大,通过上述方程式计算得出需对图5B所示的影像进行影像平移处理,处理后的影像如图5C所示。因此如图5C所示的影像能够正常显示关键信息,不会丢失所述关键信息,从而使影像显示更加和谐。
在此需要说明的是,本发明所述显示器包括但不限定为LCD、OLED或WOLED。此外,所述屏幕内孔还设置有前置影像传感器(image sensor)。所述前置影像传感器包括但不限定为感光耦合组件(charge coupled device,CCD)、互补性氧化金属半导体(complementary metal oxide semiconductor,CMOS)、红外线传感器(infrared,IR)。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术 人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。

    S402、对远离所述内孔区域的所述像素减去所述插值宽度,从而保持影像分辨率不变,其中采用帧间插值技术,确保影像能平滑过渡。
  13. 如权利要求12所述的具有屏幕内孔显示器影像处理方法,其中在步骤S401中,所述影像插值为双线性插值或Lanczos插值。
  14. 如权利要求7所述的具有屏幕内孔显示器影像处理方法,其中当所述内孔区域和所述周边区域的影像信息一样时,则判断所述内孔区域不具有所述关键信息而维持所述原始影像,当所述内孔区域和所述周边区域的影像信息存在差异时,则判断所述内孔区域具有所述关键信息而进行所述影像处理。
  15. 如权利要求7所述的具有屏幕内孔显示器影像处理方法,其中所述显示器为LCD、OLED或WOLED。
  16. 如权利要求7所述的具有屏幕内孔显示器影像处理方法,其中所述屏幕内孔还设置有前置影像传感器,所述前置影像传感器为感光耦合组件、互补性氧化金属半导体、红外线传感器。
