下面结合附图，对本公开实施例提供的显示面板的图像处理方法、驱动装置、显示面板及可穿戴设备的具体实施方式进行详细地说明。附图中各部件的形状和大小不反映真实比例，目的只是示意说明本公开的内容。
本公开实施例提供一种显示面板的图像处理方法、驱动装置、显示面板及可穿戴设备，用以解决现有的显示面板在显示非矩形的图像区域时，在显示边缘部分出现严重的锯齿感的问题，从而改善显示面板的视觉效果。
图1为本公开一实施例提供的一种图像处理方法的流程图。
例如，在本公开实施例中，显示面板可以包括主动式有机电致发光(AMOLED)显示面板等。
例如，显示面板包括显示图像区域和周边区域。显示面板上设置有阵列排布的像素阵列。周边区域包括灰阶过渡区域，灰阶过渡区域与显示图像区域相邻，显示图像区域包括沿行方向和列方向排布的多个显示像素。
如图1所示，本公开实施例提供的显示面板的图像处理方法可以包括以下步骤：
步骤S101、根据各灰阶过渡区域的位置，确定显示图像区域中在行方向或列方向上与各灰阶过渡区域相邻的相邻显示像素；
步骤S102、确定灰阶过渡区域中的过渡像素；
步骤S103、获取第一像素灰阶，所述第一像素灰阶为所述相邻显示像素的灰阶；
步骤S104、获取第二像素灰阶；
步骤S105、根据所述第一像素灰阶、所述第二像素灰阶和所述过渡像素，对所述过渡像素的第三像素灰阶进行调整，其中，所述第三像素灰阶在所述第一像素灰阶和所述第二像素灰阶之间；
步骤S106、将第三像素灰阶发送至显示面板进行显示。
例如，在本公开实施例提供的上述图像处理方法中，所述显示图像区域的形状包括非矩形形状。所述非矩形形状可以包括圆形，但不限于此，根据实际设计需要，显示图像区域的形状可以为三角形、菱形、多边形或椭圆形等，当然也可以为其他不规则形状。
为了便于用户观看，显示图像区域一般位于显示面板的中间位置。在显示面板上除了显示图像区域以外的区域均为周边区域。由于在显示面板中各像素阵列分布，例如，对于圆形的显示图像区域，在显示图像区域与周边区域之间的交界处会存在边缘锯齿问题。基于此，本公开实施例提供的图像处理方法可以对位于非矩形的显示图像区域与周边区域之间的交界处的位于灰阶过渡区域的像素进行灰度调整，以减弱边缘锯齿问题。
例如，显示面板可以为矩形显示面板，也可以为异形显示面板，例如圆形显示面板、椭圆形显示面板等。
例如，显示像素的行方向和列方向彼此垂直。
例如，在步骤S104中，第二像素灰阶可以根据实际需要预设，例如由用户预设。又例如，周边区域还可以包括背景图像区域。背景图像区域包括沿所述行方向和所述列方向阵列排布的多个背景像素。步骤S104可以包括：根据灰阶过渡区域的位置，确定背景图像区域中在所述行方向或所述列方向上与各灰阶过渡区域相邻的相邻背景像素，第二像素灰阶为相邻背景像素的灰阶。
例如，在显示图像区域中的多个显示像素的像素灰阶可以各不相同，也可以均相同。在背景图像区域中的多个背景像素的像素灰阶可以各不不相同，也可以均相同。本公开的实施例对此不作限制。
例如，在背景图像区域内，可以为背景图像区域内的所有像素都提供像素灰阶；或者，也可以仅为背景图像区域内与灰阶过渡区域相邻的一部分像素(例如相邻背景像素)提供像素灰阶(即第二像素灰阶)，而不向背景图像区域的其余区域内的像素提供像素灰阶；或者，还可以在背景图像区域内仅与灰阶过渡区域相邻的区域设置像素(例如相邻背景像素)并为该像素提供像素灰阶(即第二像素灰阶)。
需要说明的是，在本公开的描述中，像素阵列中位于显示图像区域中的像素为显示像素，位于灰阶过渡区域中的像素为过渡像素，位于背景图像区域的像素为背景像素。
例如，在执行本公开实施例提供的图像处理方法之前，可以根据显示图像区域的形状，预先确定并存储与该显示图像区域相邻的各灰阶过渡区域的位置。这样，在获取与各灰阶过渡区域相邻的显示图像区域中的相邻显示像素的第一像素灰阶和第二像素灰阶之后，可以直接根据存储的各灰阶过渡区域的位置，以及第一像素灰阶和第二像素灰阶，对各灰阶过渡区域中的过渡像素的第三像素灰阶进行调整，使第三像素灰阶在相邻显示像素的第一像素灰阶和第二像素灰阶之间，从而减小显示图像区域与周边区域之间的边缘的亮度和对比度，有效减弱边缘锯齿问题，增强客户体验。
例如，显示面板所显示的图像可以是固定的也可以随时间变化。例如，当所显示的图像是随时间变化的，则本公开的图像处理方法可以根据显示面板显示的图像实时确定灰阶过渡区域的位置并确定灰阶过渡区域的各过渡像素的第三像素灰阶，此时，根据显示图像的不同，灰阶过渡区域可能不同。但不限于此，当所显示的图像是固定的，则显示面板的灰阶过渡区域可以根据固定的显示图像提前设定，且灰阶过渡区域的各过渡像素的第三像素灰阶与相邻显示像素的第一像素灰阶和第二像素灰阶的对应关系也可以提前设定并存储在显示面板的存储器中，根据需要由处理器直接读取到缓存中进行处理。此时，灰阶过渡区域在显示过程中固定不变。
图2为本公开一实施例提供的一种图像处理方法应用于的显示面板的结构示意图，图3a为图2中数字12到1的区域的灰阶过渡区域的示意图，图3b为图2中数字1到2的区域的灰阶过渡区域的示意图，图3c为图2中数字2到3的区域的灰阶过渡区域的示意图。图4为本公开一实施例提供的一种图像处理方法应用于的显示面板的另一结构示意图；图5a为图4中第一三角子区域A1边界的灰阶过渡区域的示意图；图5b为图4中第二三角子区域A2边界的灰阶过渡区域的示意图。
例如，如图3a所示，显示图像区域的边缘包括沿所述行方向和所述列方向延伸的第一线段101和第二线段102(第一线段101表示沿行方向延伸的线段，第二线段102表示沿列方向延伸的线段)相连形成的折线，这里的显示图像区域与周边区域之间的分界线为由多个第一线段101以及多个第二线段102相连的折线，例如，如图3a-3c和图5a-5b所示，显示图像区域与周边区域之间的分界线为锯齿状的折线，也就是说，在微观(即像素级别)上，显示图像区域的微观边缘的形状为由折线围成的锯齿形状。
下面分别根据显示图像区域的微观边缘的具体形状，对于如何确定与显示图像区域相邻的各灰阶过渡区域的位置进行具体说明。
例如，灰阶过渡区域的位置可以通过下述方式确定。
步骤S102可以包括：以相邻两个线段为邻边在所述周边区域内形成虚拟矩形区域；根据所述虚拟矩形区域确定所述灰阶过渡区域中的过渡像素的数量和排列方式。例如，以相邻两个线段(例如第一线段101和第二线段102)为邻边在周边区域内形成的虚拟矩形包括M行N列的像素，M、N均为正整数。图3a示出的示例为虚拟矩形110(位于椭圆形虚线内)包括一行多列的像素的情况。
例如，在步骤S102中，根据所述虚拟矩形区域确定所述灰阶过渡区域中的过渡像素的数量和排列方式，包括：
当所述虚拟矩形区域包括一行多列像素时，各所述灰阶过渡区域包括在所述虚拟矩形区域中与所述显示图像区域相邻的位于一行的多个过渡像素；
当所述虚拟矩形区域包括多行一列像素时，各所述灰阶过渡区域包括在所述虚拟矩形区域中与所述显示图像区域相邻的位于一列的多个过渡像素；
当所述虚拟矩形区域包括一行一列像素时，各所述灰阶过渡区域包括在所述虚拟矩形区域中与所述显示图像区域相邻的一个过渡像素。
例如，虚拟矩形区域内的至少部分像素为过渡像素。例如，虚拟矩形区域内的所有像素可以均为过渡像素，如图3b所示，当虚拟矩形区域包括一行一列像素时，灰阶过渡区域可以包括位于虚拟矩形区域中的一个像素，即灰阶过渡区域可以包括一个过渡像素。又例如，如图3a所示，当虚拟矩形区域包括一行六列像素时，位于虚拟矩形区域中的同一行相邻的四个像素可以为过渡像素，即灰阶过渡区域可以包括位于同一行的四个过渡像素；如图3c所示，当虚拟矩形区域包括六行一列像素时，位于虚拟矩形区域中的同一列相邻的四个像素可以为过渡像素，即灰阶过渡区域可以包括位于同一列的四个过渡像素。
例如，过渡像素可以包括虚拟矩形区域内的所有像素和周边区域中在灰阶过渡区域的延伸方向上的部分像素。如图5a所示，当虚拟矩形区域包括一行三列像素时，灰阶过渡区域可以包括位于虚拟矩形区域中的三个像素和在第一方向(例如，第一方向表示灰阶过渡区域的延伸方向)上与虚拟矩形区域相邻的一个像素，也就是说，灰阶过渡区域可以包括位于同一行的四个过渡像素。
又例如，根据显示图像区域的具体形状，在显示图像区域与周边区域交界 处，显示图像区域的宏观边缘可以为直线，显示图像区域的宏观边缘也可以为曲线。例如，在显示图像区域的具体形状为三角形、菱形或多边形时，会出现显示图像区域的宏观边缘为直线的情况；在显示图像区域的具体形状为圆形或椭圆形时，会出现显示图像区域的宏观边缘为曲线的情况。当然，对于同一显示图像区域，也可能同时存在显示图像区域的宏观边缘为曲线和直线的情况，在此不作限定。
需要说明的是，“显示图像区域的宏观边缘”表示宏观上的显示图像区域的整体形状的边界，例如，若显示图像区域的为圆形时，则显示图像区域的宏观边缘为曲线；若显示图像区域的边界为三角形或菱形等多边形时，显示图像区域的宏观边缘为直线。
下面分别根据显示图像区域的宏观边缘为直线和曲线时具有的特点，对于如何确定与显示图像区域相邻的各灰阶过渡区域的位置进行具体说明。
例如，在步骤S102中，当显示图像区域的宏观边缘为曲线时，灰阶过渡区域的位置可以通过下述方式确定：
当显示图像区域的宏观边缘的切线与像素阵列的列方向的夹角大于第一预设夹角θ1且小于90度时，与显示图像区域相邻的各灰阶过渡区域可以包括在周边区域中与显示图像区域相邻的位于一行的多个过渡像素；
当显示图像区域的宏观边缘的切线与像素阵列的列方向的夹角大于0度且小于第二预设夹角θ2时，与显示图像区域相邻的各灰阶过渡区域可以包括在周边区域中与显示图像区域相邻的位于一列的多个过渡像素；
当显示图像区域的宏观边缘的切线与像素阵列的列方向的夹大于或等于第二预设夹角θ2且小于或等于第一预设夹角θ1时，与显示图像区域相邻的各灰阶过渡区域可以包括在周边区域中与显示图像区域相邻的一个过渡像素。
例如，第一预设夹角θ1和第二预设夹角θ2均为锐角，且第一预设夹角θ1大于或等于45度且小于90度，第二预设夹角θ2小于或等于45度且大于0度。
值得注意的是，第二预设夹角θ2一般小于第一预设夹角θ1，例如，第二预设夹角θ2可以为30度，第一预设夹角θ1一般为60度。当然，第二预设夹角θ2也可以等于第一预设夹角θ1，例如，第二预设夹角θ2和第一预设夹角θ1均为45度，在此不作限定。
例如，如图2所示，显示面板包括显示图像区域A和周边区域，显示图像区域A与周边区域之间具有第一宏观边缘100、第二宏观边缘110和第三宏观 边缘120。周边区域包括背景图像区域C和位于显示图像区域A与背景图像区域C之间的灰阶过渡区域B(图2中未示出)。显示图像区域A可以为圆形，此时，可以设定第一预设夹角为60度，第二预设夹角为30度。例如，可以将圆形的显示图像区域A沿着水平和竖直方向分平均分为四份，每份为具有90度圆心角的扇区。以图2中右上角的扇区为例，可以将扇区沿着圆心角分为三等份，该三等份包括数字12到1之间的第一扇形子区域，数字1到2之间的第二扇形子区域，数字2到3之间的第三扇形子区域。例如，第一扇形子区域与周边区域之间具有第一宏观边缘100，第二扇形子区域与周边区域之间具有第二宏观边缘110，第三扇形子区域与周边区域之间具有第三宏观边缘120。
例如，如图2和图3a所示，在第一扇形子区域内，第一宏观边缘100的法线102和第一宏观边缘100的切线101相互垂直，显示图像区域A与周边区域的第一宏观边缘100的切线101与像素阵列的列方向103的夹角α1大于60度且小于90度，因此，与第一扇形子区域相邻的各灰阶过渡区域B可以包括在周边区域中与第一扇形子区域相邻的位于一行的多个过渡像素，例如，在第一扇形子区域对应的第一宏观边缘100处，各灰阶过渡区域B可以包括位于一行的2-4个过渡像素。
例如，如图2和图3b所示，在第二扇形子区域内，第二宏观边缘110的法线112和第二宏观边缘110的切线111相互垂直，显示图像区域A与周边区域的第二宏观边缘110的切线111与像素阵列的列方向103的夹角α2大于30度且小于60度，因此，与第二扇形子区域相邻的各灰阶过渡区域B可以包括在周边区域中与第二扇形子区域相邻的一个过渡像素。
例如，如图2和图3c所示，在第三扇形子区域内，显示图像区域A与周边区域的第三宏观边缘120的切线121与像素阵列的列方向103的夹角大于0度且小于30度，因此，与第三扇形子区域相邻的各灰阶过渡区域B可以包括在周边区域中与第三扇形子区域相邻的位于一列的多个过渡像素，例如，在第三扇形子区域对应的第三宏观边缘120处，各灰阶过渡区域B可以包括位于一列的4-5个过渡像素。
上述仅是以显示图像区域为圆形为例进行举例说明，本公开实施例提供的上述图像处理方法不具体限定显示图像区域的形状。
例如，在步骤S102中，当显示图像区域的宏观边缘为直线时，灰阶过渡区域的位置可以通过下述方式确定：
当显示图像区域的宏观边缘与像素阵列的列方向的夹角大于第一预设夹角θ1且小于90度时，与显示图像区域相邻的各灰阶过渡区域可以包括在周边区域中与显示图像区域相邻的位于一行的多个过渡像素；
当显示图像区域的宏观边缘与像素阵列的列方向的夹角大于0度且小于第二预设夹角θ2时，与显示图像区域相邻的各灰阶过渡区域可以包括在周边区域中与显示图像区域相邻的位于一列的多个过渡像素；
当显示图像区域的宏观边缘与像素阵列的列方向的夹角大于或等于第二预设夹角θ2且小于或等于第一预设夹角θ1时，与边界相邻的各灰阶过渡区域可以包括在周边区域中与显示图像区域相邻的一个过渡像素。
值得注意的是，第二预设夹角θ2一般小于第一预设夹角θ1，例如，第二预设夹角θ2可以为30度，第一预设夹角θ1一般为60度。当然，第二预设夹角θ2也可以等于第一预设夹角θ1，例如，第二预设夹角θ2和第一预设夹角θ1均为45度。
例如，以显示图像区域A为如图4所示的五边形为例，说明显示图像区域的宏观边缘为直线的情况，此时，可以设定第一预设夹角θ1和第二预设夹角θ2均为45度。例如，如图4所示，可以将五边形的显示图像区域沿着中心和侧边平均分为五等份，每份为具有72度顶角的等腰三角形。五等份分别为第一三角子区域A1、第二三角子区域A2、第三三角子区域A3、第四三角子区域A4和第五三角子区域A5。第一三角子区域A1、第二三角子区域A2、第四三角子区域A4和第五三角子区域A5与周边区域的交界处，显示图像区域的宏观边缘的法线方向与像素阵列的行方向109和列方向103均不重合，而第三三角子区域A3与周边区域的交界处，显示图像区域的宏观边缘的法线方向与像素阵列的列方向103重合。因此，在第一三角子区域A1、第二三角子区域A2、第四三角子区域A4和第五三角子区域A5与周边区域的边界处均具有灰阶过渡区域(图4中未示出)。
例如，如图4和图5a所示，在第一三角子区域A1和第五三角子区域A5(即五边形顶角两侧的两个等腰三角形)内，以第一三角子区域A1为例，与第一三角子区域A1对应的宏观边缘200与像素阵列的列方向103的夹角β1为54度，故大于45度，即大于第一预设夹角θ1。因此，与宏观边缘200相邻的各灰阶过渡区域B可以包括在周边区域中与该第一三角子区域A1相邻的位于一行的多个过渡像素，例如，在第一三角子区域A1和第五三角子区域A5 对应的宏观边缘处，各灰阶过渡区域B可以包括位于一行的3-4个过渡像素。
例如，如图4和图5b所示，在第二三角子区域A2和第四三角子区域A4(即五边形底角两侧的两个等腰三角形)内，以第二三角子区域A2为例，与第二三角子区域A2对应的宏观边缘210与像素阵列的列方向103的夹角β2为18度，故小于45度，即小于第二预设夹角θ2。因此，与宏观边缘210相邻的各灰阶过渡区域B可以包括在周边区域中与该第二三角子区域A2相邻的位于一列的多个过渡像素，例如，在第二三角子区域A2和第四三角子区域A4对应的宏观边缘处，各灰阶过渡区域可以包括位于一列的4-5个过渡像素。
上述仅是以显示图像区域为五边形为例进行举例说明，本公开实施例提供的上述图像处理方法不具体限定显示图像区域的形状。
需要说明的是，在本公开中，“夹角”(即夹角α1、夹角α2、夹角α3、夹角β1和夹角β2)均为锐角。
例如，在本公开实施例提供的上述图像处理方法中，根据显示图像区域的形状，可以确定各灰阶过渡区域的位置，同时，各灰阶过渡区域包括的过渡像素的数量可能不同，例如，各灰阶过渡区域中的过渡像素的数量可能大于1。因此，可以通过多种方式调整灰阶过渡区域内的各过渡像素的第三像素灰阶，从而达到模糊化处理边缘，有效的减弱边缘锯齿感。
例如，步骤S101可以包括以下步骤：根据灰阶过渡区域的位置，确定灰阶过渡区域的延伸方向；在灰阶过渡区域的延伸方向上，确定在显示图像区域中与各灰阶过渡区域相邻的相邻显示像素。
例如，当周边区域包括背景图像区域时，步骤S101还可以包括：根据灰阶过渡区域的位置，确定灰阶过渡区域的延伸方向；在灰阶过渡区域的延伸方向上，确定在背景图像区域中与各灰阶过渡区域相邻的相邻背景图素。在步骤S104中，第二像素灰阶为相邻背景图素的灰阶。
例如，灰阶过渡区域的延伸方向可以表示在灰阶过渡区域中过渡像素的排列方向。如图3a和图5a所示，若各灰阶过渡区域包括位于一行的多个过渡像素时，灰阶过渡区域的延伸方向可以为像素阵列的行方向，即图3a和图5a中的第一方向。如图3c和图5b所示，若各灰阶过渡区域包括位于一列的多个过渡像素时，灰阶过渡区域的延伸方向可以为像素阵列的列方向，即图3c和图5b中的第二方向。如图3b所示，若各灰阶过渡区域仅包括一个过渡像素，则灰阶过渡区域的延伸方向可以为像素阵列的行方向(即图3b中的第一方向)， 也可以为像素阵列的列方向(即图3b中的第二方向)。
例如，在显示图像区域中，相邻显示像素的数量可以为1个。在背景图像区域中，相邻背景像素的数量也可以为1个。以图3a所示的第一排的灰阶过渡区域为例，在显示图像区域A中，相邻显示像素为像素10；在背景图像区域C中，相邻背景像素为像素20。
需要说明的是，相邻显示像素也可以为多个，相邻背景像素也可以为多个，此时，相邻显示像素的第一像素灰阶表示该多个相邻显示像素的第一像素灰阶的平均值，相邻背景像素的第二像素灰阶表示该多个相邻背景像素的第二像素灰阶的平均值。
例如，在步骤S105中，根据第一像素灰阶、第二像素灰阶和过渡像素，对过渡像素的第三像素灰阶进行调整可以包括：根据第一像素灰阶、第二像素灰阶、灰阶过渡区域中的过渡像素的排列方式和数量等，对过渡像素的第三像素灰阶进行调整。
例如，为了简化计算数据量，可以将灰阶过渡区域中的多个过渡像素的第三像素灰阶设置为相同的数值。例如，在灰阶过渡区域中的多个过渡像素的第三像素灰阶可以为相邻显示像素的第一像素灰阶和第二像素灰阶(例如，相邻背景像素的灰阶)的平均值。
例如，为进一步减弱边缘锯齿感，在本公开实施例提供的上述图像处理方法中，在一个示例中，步骤S105可以包括：在相邻显示像素的第一像素灰阶大于第二像素灰阶时，在灰阶过渡区域的延伸方向上，从显示图像区域指向周边区域的方向，调整灰阶过渡区域中的各过渡像素的第三像素灰阶逐渐减少。例如，若显示图2所示的黑白分明的图片时，在显示图像区域中，相邻显示像素的第一像素灰阶为白色(例如，255)，在背景图像区域中，相邻背景像素的第二像素灰阶为黑色(例如，0)，可以将灰阶过渡区域中的各过渡像素的第三像素灰阶进行逐渐降阶处理，以逐步降低亮度，从而达到边缘模糊化处理，可以有效减弱边缘锯齿感。
例如，在另一个示例中，步骤S105可以包括：在相邻显示像素的第一像素灰阶小于第二像素灰阶时，在灰阶过渡区域的延伸方向上，从显示图像区域指向周边区域的方向，调整灰阶过渡区域中的各过渡像素的第三像素灰阶逐渐增加。例如，若显示黑白分明的图片，在显示图像区域中，相邻显示像素的第一像素灰阶为黑色，在背景图像区域中，相邻背景像素的第二像素灰阶为白色， 可以将灰阶过渡区域中的各过渡像素的第三像素灰阶进行逐渐升阶处理，以逐步提高亮度，从而达到边缘模糊化处理，可以有效减弱边缘锯齿感。
又例如，在本公开实施例提供的上述图像处理方法中，灰阶过渡区域中的各过渡像素的第三像素灰阶的灰阶变化步长可以相同，从而达到最佳边缘模糊化处理效果，有效减弱边缘锯齿感。例如，以图3a所示的第一排的灰阶过渡区域中的各过渡像素的第三像素灰阶为例，例如，在左边的显示图像区域A中，相邻显示像素10的第一像素灰阶为X，在右边的背景图像区域C中，相邻背景像素20的第二像素灰阶为0。以相邻显示像素10的第一像素灰阶X为基准灰阶，相邻背景像素20的第二像素灰阶0为降阶处理的最终数值，对灰阶过渡区域B中的四个过渡像素的第三像素灰阶进行等步长的降阶处理，其中步长值为(X-0)/(4+1)(灰阶)。例如X取值为100，则步长值为20。
图6为图3a中第一行灰阶过渡区域的示意图。如图3a和图6所示，经过对灰阶过渡区域B的各过渡像素的第三像素灰阶进行调整后，在灰阶过渡区域B的延伸方向上，从显示图像区域A到背景图像区域C的方向上，灰阶过渡区域B中的各过渡像素的亮度缓慢过度，因此局部锯齿感减弱，整体上看边缘处理之后呈现模糊化状态，边缘对比度减少，达到减弱锯齿感的效果。
例如，步骤S106还包括将显示图像区域中的各显示像素的灰阶发送至显示图像区域进行显示。当周边区域包括背景图像区域，且背景图像区域设置有用于显示的背景像素时，步骤S106还包括将背景图像区域中的各背景像素的灰阶发送至背景图像区域进行显示。
需要说明的是，显示图像区域中的各显示像素的灰阶包括第一像素灰阶，背景图像区域中的各背景像素的灰阶包括第二像素灰阶。
例如，在步骤S106中，显示图像区域中的各显示像素的灰阶、背景图像区域中的各背景像素的灰阶以及第三像素灰阶可以由显示面板的主板发送至显示面板。
