基于上述问题,本申请实施例提供一种画面显示调节方法、装置、存储介质及显示设备,可以提高图像显示质量。以下分别进行详细说明。需说明的是,以下实施例的描述顺序不作为对实施例优选顺序的限定。
请参考图1,图1为本申请实施例提供的一种画面显示调节方法的流程示意图。该画面显示调节方法可以应用于诸如电视机等显示设备。该画面显示调节方法的具体流程可以如下:
101、获取当前显示画面在多个颜色通道的亮度信息。
其中,当前显示画面可以是视频播放过程中的视频帧图像,该视频帧图像可以为图像亮度异常的视频帧图像,图像亮度异常可以为在同一视频画面中,相同颜色显示区域存在亮度差异。采集该视频帧图像可以通过多种方式,比如,可以输入程序指令,通过程序指令获取视频帧图像,作为当前显示画面。
例如,用户通过显示设备进行视频播放,当视频画面亮度出现异常时,可以暂停视频播放,通过输入程序指令,截取当前视频帧图像,作为当前显示画面。
在获取到当前显示画面之后,进一步的,获取当前显示画面在多个颜色通道的亮度信息,其中,多个颜色通道可以包括红色通道,绿色通道,蓝色通道。
在一实施例中,每个图像都有一个或多个颜色通道,图像中默认的颜色通道数取决于其颜色模式,即一个图像的颜色模式将决定其颜色通道的数量。例如,RGB图像有3个通道,分别为红色通道(red),绿色通道(green)。蓝色通道(blue)。在默认情况下,位图模式、灰度、双色调和索引颜色图像只有一个通道。
其中,每个颜色通道都存放着图像中颜色元素的信息。所有颜色通道中的颜色叠加混合产生图像中像素的颜色。比如,以RGB模式图像为例,其颜色通道原理为:一幅图像的基本组成单位是以RGB为基础展开的,为此可以理解为一个图像由RGB这样的三个元素组成,R为一个红色通道,表示为1;G为一个绿色通道,表示为2;B 为一个蓝色通道,表示为3;有一处白色图像则为4,它是由1、2、3处的通道颜色混合而成,这相当于我们使用的调色板,几种颜色混合在一起将产生一种新的颜色。
在一些实施例中,在步骤获取当前显示画面在多个颜色通道的亮度信息之前,还可以包括:
当检测到画面显示时,判断所述显示设备的显示条件是否满足预设显示条件;
若否,则重置所述显示设备中与所述显示条件对应的显示参数。
其中,画面显示可以包括多种,比如,可以为显示静止图像,也可以为显示动态视频等等。可以通过接收用户显示指令,根据显示指令显示画面。显示设备可以为电视,用户可以通过多种方式触发显示指令,比如,用户可以对显示设备的物理按键的操作,显示屏的触摸操作,或者通过其他遥控设备的操作来触发显示设备开始显示画面。
在一实施例中,显示设备的显示条件可以包括对不同显示参数的设置。其中,显示参数可以表示当前显示设备在出厂前设置的与亮度或者色度相关等参数,比如,白平衡,灰阶,颜色饱和度等等,可以提高图像显示质量。例如,可以通过该显示参数提高显示设备在播放视频时,提高视频图像的亮度,对比度,颜色饱和度等等。
在本实施例中,显示参数可以包括白平衡,白平衡是电视摄像领域一个非常重要的概念,通过它可以解决色彩还原和白平衡色调处理的一系列问题。白平衡是随着电子影像再现色彩真实而产生的,在专业摄像领域白平衡应用的较早,它是实现摄像机图像能精确反映被摄物的色彩状况,有手动白平衡和自动白平衡等方式。其工作原理为:摄像机内部有三个CCD(Charge Coupled Device,图像传感器)电子耦合元件,他们分别感受蓝色、绿色、红色的光线,在预置情况下这三个感光电路电子放大比例是相同的,为1:1:1的关系,白平衡的调整就是根据被调校的景物改变了这种比例关系。比如被调校景物的蓝、绿、红色光的比例关系是2:1:1(蓝光比例多,色温偏高),那么白平衡调整后的比例关系为1:2:2,调整后的电路放大比例中明显蓝的比例减少,增加了绿和红的比例,这样被调校景物通过白平衡调整电路到所拍摄的影像,蓝、绿、红的比例才会相同。也就是说如果被调校的白色偏一点蓝,那么白平衡调整就改变正常的比例关系减弱蓝电路的放大,同时增加绿和红的比例,使所成影像依然为白色。
其中,在确定显色参数之后,可以获取显色参数的参数值,可以为预先设置的白平衡的参数值,之后可以对该参数值进行调节。具体的,可以根据实际需求设置相应的白平衡参数值,比如,可以将白平衡参数值设置为0,可以表示关闭显示设备的白平衡功能,则此时视频播放的图像画面的成像效果为原始的图像效果。
当对显示参数进行调节之后,可以根据调节后的显示参数继续显示画面。
102、根据亮度信息从多个颜色通道中确定亮度异常的目标颜色通道。
其中,颜色通道的亮度信息可以包括该颜色通道在每个灰阶的亮度值。灰阶,是将最亮与最暗之间的亮度变化区分为若干份。以便于进行信号输入相对应的屏幕亮度管控。每张数字影像都是由许多点所组合而成的,这些点又称为像素(pixels),通常每一个像素可以呈现出许多不同的颜色,它是由红、绿、蓝(RGB)三个子像素组成的。每一个子像素,其背后的光源都可以显现出不同的亮度级别。而灰阶代表了由最暗到最亮之间不同亮度的层次级别。这中间层级越多,所能够呈现的画面效果也就越细腻。以8bit panel为例,能表现2的8次方,等于256个亮度层次,我们就称之为256灰阶。LCD(Liquid Crystal Display ,液晶显示器)屏幕上每个像素,均由不同亮度层次的红、绿、蓝组合起来,最终形成不同的色彩点。也就是说,屏幕上每一个点的色彩变化,其实都是由构成这个点的三个RGB子像素的灰阶变化所带来的。
在一些实施例中,亮度信息可以包括亮度曲线,该亮度曲线可以用于表征亮度值随灰阶值变化而产生的变化,则步骤根据多个颜色通道亮度信息确定目标颜色通道,可以包括:
基于所述亮度曲线获取每相邻两个灰阶对应的亮度值差值;
当所述亮度值差值不处于预设差值范围内时,则将所述亮度值差值对应的颜色通道确定为所述目标颜色通道。
其中,每个颜色通道的颜色信息可以包括灰阶亮度变化曲线,比如,可以将预设灰阶区间的灰阶作为一个坐标轴,将亮度值作为另一坐标轴,通过这两个坐标轴构建一个坐标空间,基于每一灰阶对应的亮度值,确定多个坐标点,连接所有坐标点,则可以确定颜色通道的灰阶亮度变化曲线。其中,预设灰阶区间可以包括0至255阶灰阶。
在获取到颜色通道的灰阶亮度变化曲线之后,可以每相邻两个灰阶对应的亮度值的差值,比如,灰阶坐标轴的起始点可以为0阶灰阶,沿着灰阶坐标轴的箭头方向依次为1阶灰阶,2阶灰阶,3阶灰阶...255阶灰阶,则可以获取1阶与0阶的亮度值差值,2阶与1阶的亮度值差值,3阶与2阶的亮度值差值...255阶与254阶的亮度值差值,将所有亮度值差值与预设差值范围进行比较。
其中,预设差值范围可以为0.01~0.02等等,在此不作限定,可以根据实际情况进行设置,设置预设差值范围可以判断各阶灰阶的亮度均匀是否过度,若亮度值差值处于预设差值范围,则可以确定该颜色通道在各灰阶的亮度均匀过度。若亮度差值未处于预设差值范围,则可以确定该颜色通道的灰阶亮度变化出现异常,则可以将该颜色通道确定为目标颜色通道。
103、获取目标颜色通道的刺激量信息,并基于所述刺激量信息从预设灰阶区间中确定目标灰阶。
在确定目标颜色通道之后,可以获取该颜色通道的刺激量信息。
其中,刺激量可以包括多个,在三色系统中,与待测光达到颜色匹配所需的三种原色刺激的量。用X(红原色刺激量)、Y(绿原色刺激量)和Z(蓝原色刺激量)表示。色的感觉是由于三种原色光刺激的综合结果。在红、绿,蓝三原色系统中,红。绿、蓝的刺激量分别以R、G、B表示之。由于从实际光谱中选定的红、绿、蓝三原色光不可能调(匹)配出存在于自然界的所有色彩,所以,CIE于1931年从理论上假设了并不存在于自然界的三种原色,即理论三原色,以X,Y,Z表示,以期从理论上来调配一切色彩。形成了XYZ测色系统。X原色相当于饱和度比光谱红还要高的红紫,Y原色相当于饱和度比520毫微米的光谱绿还要高的绿,Z原色相当于饱和度比477毫微米的光谱蓝还要高的蓝。这三种理论原色的刺激量以X,Y,Z表示之,即所谓的三刺激值。
其中,该目标颜色通道的刺激量信息可以包括刺激值X、刺激值Y和刺激值Z分别在各灰阶的参数值。
在一实施例中,刺激量信息可以包括刺激量曲线,该刺激量曲线可以表征刺激值随灰阶变化而产生的变化,则步骤基于所述刺激量信息从预设灰阶区间中确定目标灰阶,可以包括:
(1)确定每一刺激量曲线的变化趋势;
(2)根据所述变化趋势从多条刺激量曲线中确定异常刺激量曲线;
(3)基于所述异常刺激量曲线中的刺激值变化信息,从所述预设灰阶区间中确定所述目标灰阶。
其中,刺激量信息中可以包括原色刺激量X、原色刺激量Y和原色刺激量Z的刺激量曲线。比如,可以将预设灰阶区间的灰阶作为一个坐标轴,将刺激值作为另一坐标轴,通过这两个坐标轴构建一个坐标空间,基于每一灰阶对应的刺激值,确定做个坐标点,连接所有坐标点,则可以确定原色刺激量的刺激量曲线。
在获取到原色刺激量X、原色刺激量Y和原色刺激量Z分别对应的刺激量曲线之后,可以根据每一刺激量曲线的变化趋势,从预设灰阶区间中确定目标灰阶。
在一实施例中,步骤根据所述变化趋势从多条刺激量曲线中确定异常刺激量曲线,可以包括:
(2.1)根据所述变化趋势确定刺激量曲线中每一灰阶向相邻下一灰阶过度的刺激值变化量;
(2.2)若所述变化量大于预设变化量,则确定所述变化量对应的刺激量曲线为异常刺激量曲线。
其中,刺激量曲线的变化趋势可以包括每相邻两阶对应的刺激值变化情况,则变化趋势信息可以包括预设灰阶区间的每一灰阶向对应下一灰阶过度的变化值。
其中,预设灰阶区间可以为0~255阶灰阶,则样本灰阶可以包括0阶,1阶,2阶...255阶。例如,预设灰阶区间在刺激量曲线的坐标轴空间中的排列可以为0阶,1阶,2阶...255阶,则每一灰阶向相邻下一灰阶过度的刺激值变化量可以为0阶对应的刺激值过度至1阶对应的刺激值产生的变化值等等,依次获取相邻灰阶对应的刺激值变化值。
又例如,预设灰阶区间在刺激量曲线的坐标轴空间中的排列可以为255阶,254阶,253阶...0阶,则每一灰阶向相邻下一灰阶过度的刺激值变化量可以为255阶对应的刺激值过度至254阶对应的刺激值产生的变化值等等,依次获取相邻灰阶对应的刺激值变化值。
在一实施例中,步骤基于所述异常刺激量曲线中的刺激值变化信息,从所述预设灰阶区间中确定所述目标灰阶,可以包括:
(3.1)获取所述异常刺激量曲线的第一刺激值和第二刺激值,所述第一刺激值为所述异常刺激量曲线中的第一最大刺激值,所述第二刺激值为所述异常刺激量曲线在所述预设灰阶区间中最高灰阶的刺激值;
(3.2)获取所述第一刺激值和所述第二刺激值的刺激值差值;
(3.3)若所述刺激值差值大于预设阈值,则将所述异常刺激量曲线在第一刺激值对应的灰阶作为所述目标灰阶。
其中,刺激量曲线可以包括第一刺激值和第二刺激值,第一刺激值可以为该刺激量曲线中的最大刺激值,第二刺激值可以为255阶对应的刺激值。
在获取到异常刺激量曲线对应的第一刺激值和第二刺激值之后,可以计算异常刺激量曲线中,第一刺激值和第二刺激值的刺激值差值。将刺激值差值与预设阈值进行比较,若刺激值差值大于预设阈值,则可以将该异常刺激量曲线中的第一次刺激值对应的灰阶作为目标灰阶。其中,第一刺激值和第二刺激值的差值,表示为第一刺激值减去第二刺激值得到的数值,通过第一刺激值和第二刺激值的差值与预设阈值进行比较,判断在刺激量曲线中,是否存在样本灰阶对应的刺激值大于255阶对应的灰阶值,由此可以确定异常刺激量曲线中的反转灰阶也即目标灰阶。
在一实施例中,步骤基于所述刺激量信息从预设灰阶区间中确定目标灰阶,还可以包括:
从多条刺激量曲线中确定第二最大刺激值所在的刺激量曲线,作为目标刺激量曲线;
从所述目标刺激量曲线中,确定与所述最大刺激值对应的灰阶,作为所述目标灰阶。
具体的,可以通过获取每一刺激量曲线中的最大刺激值,将多个最大刺激值进行比较,确定值最大的最大刺激值,将该刺激值对应的灰阶,作为目标灰阶。
104、确定目标灰阶对应的亮度和色度,并根据目标灰阶对应的亮度和色度对显示画面进行调节。
其中,目标灰阶的亮度和色度可以为当前目标灰阶对应的亮度值和色度值,通过预设计算方式,对目标灰阶的亮度值和色度值进行计算,从而可以得到目标灰阶之前的各灰阶的亮度值和色度值。
在一些实施例中,步骤根据所述目标灰阶的亮度和色度对显示设备图像显示的亮度和色度进行调节,可以包括:
判断所述目标灰阶是否为所述预设灰阶区间中的最高灰阶;
若否,则基于所述目标灰阶的亮度值与色度值,更新所述最高灰阶的亮度值与色度值;
基于更新后的所述最高灰阶的亮度值与色度值,对所述预设灰阶区间的其他灰阶的亮度值与色度值进行处理。
其中,在确定目标灰阶之后,可以首先判断该目标灰阶是否为预设灰阶区间的最高灰阶,也即255阶。若目标灰阶不是最高灰阶,则将该目标灰阶的亮度和色度作为最高灰阶的亮度和色度,相应的,在对最高灰阶的亮度和色度进行调节,对其他灰阶的亮度和色度进行处理。
在一实施例中,步骤根据所述目标灰阶对应的亮度和色度对显示画面进行调节,可以包括:
获取所述亮度的亮度参数值,以及所述色度参数的色度值;
获取相邻两个灰阶之间的亮度差值;
根据所述亮度参数值与所述亮度差值确定所述预设灰阶区间的每一灰阶的目标亮度值;
基于每一灰阶的目标亮度值对每一灰阶的亮度值进行调节,以及基于所述目标灰阶的色度值对每一灰阶的色度值进行调节。
具体的,根据目标灰阶的亮度和色度,对其他灰阶的亮度和色度进行处理。首先,对其他灰阶的亮度进行处理,可以根据目标灰阶亮度和亮度曲线 Gamma 2.2 计算出各阶亮度。其中, Gamma是用来表征显示器件亮度响应特性的一个参数。通常显示器件显示的亮度与输入电平的关系接近一条指数曲线Gamma曲线是一种特殊的色调曲线,当Gamma值等于1的时候,曲线为与坐标轴成45度的直线,这个时候表示输入和输出密度相同。高于1的Gamma值将会造成输出亮化,低于1的Gamma值将会造成输出暗化。总之,我们的要求是输入和输出比率尽可能地接近于1。
在本实施例中,Gamma值可以为2.2目标灰阶的亮度值可以通过公式:a^Gamma,来进行计算,其中,a=gray/255,也即目标灰阶数值与255的比值。例如,目标灰阶可以为254,则根据a=gray/255,可以得到a的值为0.996,根据公式a^Gamma进行计算,确定目标灰阶的亮度值可以为0.991,则可以确定目标灰阶的亮度值为0.991。在确定每一灰阶的亮度值之后,对每一灰阶的亮度值进行调节。
在确定目标灰阶的亮度值之后,可以将最高阶灰阶的亮度值调节为目标灰阶的亮度值,之后根据相邻两个灰阶的预设亮度值差值,依次设定各个灰阶对应的亮度值。例如,255阶的亮度值为0.991,预设亮度值差值可以为0.004,则可以计算得出254阶的亮度值为0.987,253阶的亮度值可以为0.983,...,0阶亮度值为0等等。
其次,根据目标灰阶的色度值对其他灰阶的色度值进行调节,根据目标灰阶的刺激量信息,按照预设公式进行计算,得到目标灰阶的色度x与色度y。具体的,各灰阶色度一般用x和y表示。灰阶色度x= X/(X+Y+Z),色度y= Y/(X+Y+Z),XYZ为色度学定义的三刺激值,而各灰阶的三刺激值=R+G+B三刺激值和,也即在当前图像中,255阶灰阶对应的三刺激值和=(红色X+绿色X+蓝色X)+(红色Y+绿色Y+蓝色Y)+(红色Z+绿色Z+蓝色Z),则灰阶色度x= (红色X+绿色X+蓝色X)/[(红色X+绿色X+蓝色X)+(红色Y+绿色Y+蓝色Y)+(红色Z+绿色Z+蓝色Z)];灰阶色度y=(红色Y+绿色Y+蓝色Y)/[(红色X+绿色X+蓝色X)+(红色Y+绿色Y+蓝色Y)+(红色Z+绿色Z+蓝色Z)]。
例如,目标灰阶可以为254阶,则获取到254阶对应的红色X的值为140,绿色X的值为180,蓝色X的值为150;红色Y的值为80,绿色Y的值为320,蓝色Y的值为50;红色Z的值为10,绿色Z的值为52,蓝色Z的值为700,则根据上述计算公式,可以计算得到254阶的灰阶色度x为:0.279,灰阶色度y为:0.268。根据白平衡调试原理,在确定最高阶的灰阶色度之后,可以将其他各阶的灰阶色度设定为与最高阶灰阶色度相同即可。也即,将其他灰阶的灰阶色度x设定为0.279,灰阶色度y设定为0.268。即可以实现根据目标灰阶的亮度和色度对其他灰阶的亮度和色度进行调节,以达到提高图像显示质量的效果。
本申请实施例公开了一种画面显示调节方法,该画面显示调节方法包括:获取当前显示画面在多个颜色通道的亮度信息;根据所述亮度信息从多个颜色通道中确定亮度异常的目标颜色通道;获取所述目标颜色通道的刺激量信息,并基于所述刺激量信息从预设灰阶区间中确定目标灰阶;确定所述目标灰阶对应的亮度和色度,并根据所述目标灰阶对应的亮度和色度对显示的画面进行调节。本申请方案通过采集亮度显示异常的图像画面,提取该图像画面的亮度信息,根据亮度信息确定图像画面的灰阶异常信息,基于该灰阶异常信息对图像画面进行显示参数调节,减小图像画面的亮度差异,从而可以提高图像显示质量。
参考图2,图2为本申请实施例提供的另一种画面显示调节方法的流程示意图。该画面显示调节方法的具体场景应用可以如下:
201、显示装置接收用户触发的视频播放指令,根据视频播放指令开始播放视频。
在一实施例中,显示装置可以为电视设备,该电视设备的显示面板可以为液晶显示面板。用户可以通过打开该显示装置的开关启动显示装置,并选择视频进行播放,该视频可以为本地视频,也可以为在线视频等。
当显示装置接收到用户的播放指令之后,即可以开始播放视频,则当前显示装置的显示屏为视频播放界面。
202、显示装置接收用户输入的参数调节指令,根据参数调节指令调节显示参数。
其中,参数调节指令可以为关闭显示装置的白平衡,比如,当前显示装置在进行视频播放时,设置有白平衡参数,通过接收用户的参数调节指令,通过将白平衡参数值调节为0,以达到关闭当前显示装置的白平衡功能。
203、当检测到视频画面的亮度过度出现异常时,获取异常图像画面。
在视频播放过程中,当用户观察到视频画面的亮度出现异常时,亮度异常现象在上述实施例中已进行说明,在此不多做赘述。可以获取亮度异常的图像画面,作为异常图像画面。其中,可以通过多种方式进行获取,比如,可以通过外部程序控制,获取视频中的视频帧,也即初始图像画面,这样可以保证获取到的异常图像的图像信息最大还原。
204、获取异常图像画面的在不同颜色通道的亮度曲线。
具体的,在采集到的异常图像画面之后,可以根据将该异常图像画面载入图像处理应用程序中进行分析,可以得到该异常图像画面在不同颜色通道的亮度曲线。由于本申请实施例可以是针对电视机设备类型的显示装置,则颜色通道可以包括红色通道,绿色通道和蓝色通道。
在一实施例中,请参阅图3,图3为本申请实施例提供的一种画面显示调节方法的灰阶亮度曲线图。图3包括了多个颜色通道的亮度曲线:亮度曲线S1,亮度曲线S2,亮度曲线S3。每一亮度曲线的坐标空间可以包括两个坐标轴,分别为灰阶和亮度值。其中,亮度曲线S1可以为蓝色通道的亮度曲线,亮度曲线S2可以为红色通道的亮度曲线,亮度曲线S3可以为绿色通道的亮度曲线。
205、根据不同颜色通道的亮度曲线确定目标颜色通道。
当获取到各个颜色通道的亮度曲线之后,可以通过比较各个亮度曲线的变化趋势,确定变化趋势异常的亮度曲线,将变化趋势异常的亮度曲线对应的颜色通道,可以作为目标颜色通道。
例如,通过图3所示的三个亮度变化曲线,可以确定亮度曲线S1的变化趋势出现异常,由于亮度曲线S1对应的颜色通道为蓝色通道,则可以将蓝色通道作为目标颜色通道。
206、获取目标颜色通道的多个原色刺激量的刺激量曲线。
在一实施例中,当确定目标颜色通道之后,目标颜色通道可以是异常图像画面中的异常颜色通道,可以通过对异常颜色通道进行处理,以达到改善图像亮度显示异常的问题。
获取该目标颜色通道的多个原色刺激量的刺激量曲线。其中,多个原色刺激量可以包括红色刺激量,绿色刺激量和蓝色刺激量。
例如,请参考图4,图4为本申请实施例提供的一种画面显示调节方法的灰阶刺激量曲线图。图4中可以包括:第一刺激量曲线,第二刺激量曲线以及第三刺激量曲线,其中,第一刺激量曲线可以为绿色刺激量在各灰阶的刺激值变化,第二刺激量曲线可以为蓝色刺激量在各灰阶的刺激值变化,第三刺激量曲线可以为红色刺激量在各灰阶的刺激值变化。
其中,每一刺激量曲线所在的坐标空间可以包括两个坐标轴,灰阶和刺激值。
207、根据多个刺激量曲线确定反转灰阶。
其中,可以获取每一刺激量曲线的第一刺激值和第二刺激值,如图4所示,第一刺激值可以为刺激量曲线的最大刺激值,第二刺激值可以为255阶对应的刺激值。具体的,根据每一刺激量曲线的第一刺激值和第二刺激值,确定该刺激量曲线的刺激值差值。
在确定每一刺激量曲线的刺激值差值之后,可以根据多个刺激值差值确定最大刺激值差值,可以将最大刺激值差值对应的刺激量曲线作为目标刺激量曲线,获取该目标刺激量曲线的第一刺激值曲对应的灰阶,可以作为目标灰阶。
例如,在图4中,第一刺激量曲线中:第一刺激值为700,第二刺激值为600;第二刺激量曲线中:第一刺激值为110,第二刺激值为110;第三刺激量曲线中,第一刺激值为90,第二刺激值为100;则可以确定第一刺激量曲线的刺激值差值为100,第二刺激量曲线的刺激值差值为0,第三刺激量曲线的刺激值差值为10,进一步的,可以确定最大刺激值差值可以为100。最大刺激值差值对应第一刺激量曲线,则可以将第一刺激量曲线的第一刺激值对应的灰阶254阶作为反转灰阶,反转灰阶可以表示为刺激量曲线中的刺激值转折点,在最高阶灰阶之前,出现大于最高阶灰阶对应的刺激值。
208、获取反转灰阶的亮度和色度,对预设灰阶区间的其他灰阶的亮度和色度进行调节。
在一实施例中,当确定反转灰阶之后,可以获取反转灰阶的亮度和色度,进一步的,将反转灰阶的亮度和色度作为最高阶灰阶的亮度和色度,基于调节后的最高阶灰阶的亮度和色度对其他灰阶的亮度和色度进行调节。其中,调节规则以在上述实施例中进行详细说明,请参见上述实施例,在此不多做赘述。
在一实施例中,请参考图5,图5为本申请实施例提供的一种画面显示调节方法的参数调节结果对比示意图。其中,图5包括了每一灰阶对应的白平衡参数,折线A可以表示为对显示画面进行亮度和色度调节之前的白平衡数值变化,折线B可以表示为对显示画面进行亮度和色度调节之后的白平衡数值变化。根据图5所示的对比结果,折线A在灰阶高阶254阶的白平衡参数值过度到下一灰阶时,出现突变,变化较大,影响了显示画面的显示效果。进一步的,通过本申请方案中显示调节方法,改善了白平衡参数突变,使得白平衡参数在灰阶高阶均匀过度,从而改善画面显示效果,如图5中折线B所示。
