图1为本发明实施例提供的一种基于LCD液晶板的图像生成方法的流程图,本实施例可适用于图像生成,该方法可以由图像生成设备如手机、智能摄像头、智能头盔等来实施,具体包括如下步骤:
步骤S101、获取外部光照强度,根据所述外部光照强度确定LCD液晶板的光线通过率。
在一个实施例中,外部光照强度为摄像头当前所处环境的环境光强度,如室内环境、室外环境、白天环境、夜晚环境等。其中,LCD液晶板的构造原理是在两片平行的玻璃当中放置液态的晶体,两片玻璃中间有许多垂直和水平的细小电线,透过通电与否来控制杆状水晶分子改变方向,将光线折射出来产生画面。
本方案中的图像生成设备包括有摄像头以及和摄像头关联的LCD液晶板。其中,LCD液晶板设置于摄像头的镜头和图像传感器之间或摄像头的镜头设置于LCD液晶板和图像传感器之间。
其中,光线通过率用于表征光线通过的程度,针对LCD液晶板而言表征了其透明程度,在图像生成过程中, 光线通过摄像头镜头和LCD液晶板后照射到图像传感器,以生成图像信号,再通过相应的图像信号处理装置/程序进行信号处理以生成图像。
在一个实施例中,进行外部光照强度的获取,根据该外部光照强度来确定LCD液晶板的光线通过率。其中,不同的外部光照强度对应不同的LCD液晶板的光线通过率。示例性的,可以是在智能摄像头开始运行后,进行外部光照强度的获取,以确定对应的LCD液晶板的光线通过率;还可以是当检测到拍照功能开启后,进行外部光照强度的获取,以确定对应的LCD液晶板的光线通过率。在另一个实施例中,该光线通过率还可以是根据用户的设定指令确定,如果用户输入设定的光线通过率,作为调节的依据。
步骤S102、根据所述光线通过率确定对应的调节电压或调节电流。
其中,调节电压或调节电流用于对LCD液晶板的通电电压或通电电流进行调节控制。不同的光线通过率对应不同的调节电压和调节电流。通过调节电压或调节电流的控制以实现LCD液晶板的对光线进行遮挡/非遮挡。
具体的,如图2所示,图2为一种示例性的液晶屏原理示意图。LCD液晶板以TN型液晶为例,TN型液晶是顺着长轴方向串接,长轴间彼此平行方式排列。当接触到槽装表面时,液晶分子就会顺着槽的方向排列于槽中。当液晶被包含在两个槽状表面中间,且槽的方向互相垂直,则液晶分子的排列为:上表面分子:沿着a方向;下表面分子:沿着b方向;介于上下表面中间的分子:产生旋转的效应。因此液晶分子在两槽状表面间产生90度的旋转。其偏转效果图如图3所示,图3为一种示例性的液晶分子翻转效果图。其中,液晶在电压做用下均匀分布,即当在上下表面之间加电压时,液晶分子会顺着电场方向排列,形成直立排列的现象。此时入射光线不受液晶分子影响,直线射出下表面。
图4为一种示例性的液晶偏光特性示意图。LCD液晶板存在偏光板的特性,如图4(上)所示,将非偏极光(一般光线)过滤成偏极光,当非偏极光通过a方向的偏光片时,光线被过滤成与a方向平行的线性偏极光,线性偏极光继续前进,通过第二片偏光片时,光线通过;如图4(下)所示,线性偏极光继续前进,通过第二片时,光线被完全阻挡。在具体的对光线通过性的控制过程中,当上下偏光片相互垂直时,即角度为90度,若未施加电压,光线可通过,当施加电压时,光线会被相应遮挡。在对LCD液晶板施加电压后,电流通过电晶体产生电场变化,造成液晶分子偏转,由此以改变光线的偏极性,再通过设置的偏光片对通过的光线进行遮挡/通过,以实现不同的明暗状态。
图5为另一种示例性的液晶屏原理示意图。图6为另一种示例性的液晶屏原理示意图。其中,与图2所示的最大区别在于不需要偏振光片,以及液晶容器内壁没有设有槽状表面。当没有通电时,如图5所示,由于没有内壁槽状表面的牵引,其内部所含有的液晶分子呈现无序排列状态,光线无法透过玻璃膜,这时看到的状态就是白色非透明状态。当通电的条件下,如图6所示,其内部液晶分子有序排列,光线可以顺利透过玻璃膜,这时看到的状态就是透明状态。
由前述描述可知,不同的调节电压施加在LCD液晶板上可以控制光线的通过率以实现图像明暗状态的改变。同理,可根据不同的调节电流施加在LCD液晶板上可以控制光线的通过率以实现图像明暗状态的改变。在一个实施例中,在根据外部光照强度确定光线通过率后,相应的确定该光线通过率对应的调节电压。
步骤S103、控制所述LCD液晶板的电压或电流为所述调节电压或调节电流,以使所述LCD液晶板对通过光线进行处理后通过所述图像传感器进行感应以生成图像。
其中,在确定和光线通过率对应的调节电压或调节电流后,相应的对LCD液晶板施加相应的调节电压或调节电流以控制光线通过率后,通过图像传感器进行感应生成信号,再通过控制模块或CPU进行信号处理以生成最终的图像。
在一个实施例中,为保证图像成像效果良好,当外部光照强度过强时,通过LCD液晶板进行光线遮挡;当外部光照强度减弱时,再相应减少LCD液晶板对光线的遮挡,由此以提升图像质量。
由上述方案可知,本方案中的图像生成方法基于LCD液晶板,其包括摄像头以及和所述摄像头关联的LCD液晶板,其中,LCD液晶板设置于摄像头的镜头和图像传感器之间或摄像头的镜头设置于LCD液晶板和所述图像传感器之间,通过获取外部光照强度,根据所述外部光照强度确定LCD液晶板的光线通过率,根据所述光线通过率确定对应的调节电压或调节电流,控制所述LCD液晶板的电压或电流为所述调节电压或调节电流,以使所述LCD液晶板对通过光线进行处理后通过所述图像传感器进行感应以生成图像。本方案巧妙的将LCD液晶板与摄像头相结合,并根据外部的光照强度来实现对应图像明暗的调节后生成图像,优化了摄像成像机制,扩充了摄像头的实现的功能。同时,该种控制方式便于安装,减小了摄像头模组的整体体积大小。

步骤S804、判断所述光线通过率是否大于第一设定阈值,如果是,则执行步骤S805。
在一个实施例中,摄像头集成设置有滤光片,其中,滤光片采用双通截止滤光片设计,第一通道为可见光光谱,对应通过的波长为400纳米至700纳米,第二通道为近红外光谱,对应通过的波长为820纳米、850纳米、890纳米、920纳米和/或940纳米。在外部光照强度不大于设定阈值时,其确定出对应的光线通过率后,进一步的根据该光线通过率确定是否进行辅助图像处理。具体的,所述光线通过率是否大于第一设定阈值,该第一设定阈值示例性的为100%,即在较暗环境下,光线通过率已经达到100%时,由于会400纳米至700纳米的近红外线会通过滤光片(补光),进而会导致图形泛红的问题,故在满足该条件时,跳转至步骤S805以对所述图像传感器采集的图像进行白平衡处理以减少图像泛红。
