Description

基于LCD多晶元板的图像生成方法、装置、设备和存储介质 技术领域
本申请实施例涉及图像领域，尤其涉及一种基于LCD多晶元板的图像生成方法、装置、设备和存储介质。
背景技术
图像传感器是摄像头的主要元器件，由于图像传感器是非常精密的感光元器件，所以，强光会加速图像传感器的老化，严重影响摄像头的使用寿命；当过度强烈的光高于摄像头的宽动态范围的时候，摄像头所拍摄的图片偏白或颜色过浅，影像拍摄质量；当环境光过暗并低于摄像头的宽动态范围的时候，摄像头所拍摄的图片偏暗或颜色过深，影像拍摄质量；外部光线各种各样，单一深度的光线过滤片无法满足实际的需求；在人脸识别领域，具有立体视觉的可见光加近红外的双目摄像头是一种已有的技术形态，如果近红外摄像头可以有IR-CUT功能切换到可见光，则其立体视觉可以实现VR摄像头功能，大大扩充手机现有的功能，可是手机厚度往往只有1厘米，如果用机械式IR-CUT无法实现小型化目的。
当摄像头应用在对比度强烈的环境拍摄的时候，例如向着太阳的时候，很难拍摄周边的影像；例如拍摄背光人像的时候，由于收到背光影响无法拍清楚人像；例如行车记录仪或智能驾驶***在出隧道口的时候等，由于受到隧道口强光的影响，无法清晰拍摄隧道口的影像；同样，在进入隧道口的时候，由于隧道里面的光线过暗，与外部光线形成强烈的对比，也无法清晰拍摄隧道里面的影像。

具体实施方式
下面结合附图和实施例对本发明实施例作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅用于解释本发明实施例，而非对本发明实施例的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明实施例相关的部分而非全部结构。
图1为本发明实施例提供的一种基于LCD多晶元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、智能摄像头等来实施，具体包括如下步骤：
步骤S101、确定当前图像生成场景下对应的光照调整策略。
在一个实施例中，对图像场景进行了区别划分。图像生成场景指对当前拍摄的图像进行识别或预览以确定出的具体的场景。示例性的，如果识别出预览图像存在强光区域，则相应的该图像生成场景为强光场景，对应的光照调整策略为强光遮挡策略；如果识别出预览图像存在背光情况，则相应的该图像生成场景为背光场景，对应的光照调整策略为背光拍照策略。
本方案中，针对不同的场景设置有不同的光照调整策略。
步骤S102、根据所述光照调整策略控制所述LCD多晶元板对通过的光线强度进行控制，使得调节后的光线通过图像传感器的感应以生成图像。
在一个实施例中，在确定出光照调整策略后，通过控制LCD多晶元板的方式对通过的光线强度进行控制，来实现对光线的调节后，使得调节后的光线通过图像传感器的感应以生成图像。
本方案中，包括摄像头以及和所述摄像头关联的LCD多晶元板，所述LCD多晶元板设置于所述摄像头的镜头和图像传感器之间或所述摄像头的镜头设置在所述LCD多晶元板和所述图像传感器之间，通过对该LCD多晶元板的控制以实现不同场景下的光线强度控制。具体的，控制方式可以是，以强光遮挡策略为例，包括：确定当前拍摄画面中的强光区域，通过所述LCD多晶元板降低所述强光区域的光线通过率。以背光拍照策略为例，控制方式包括：确定当前拍摄画面中的拍摄目标；确定所述拍摄目标对应的强光区域，通过所述LCD多晶元板降低所述强光区域的光线通过率。
具体的，对LCD多晶元板的控制可以采用不同的调节电压或电流对所述LCD多晶元板中的对应晶元的光线通过率进行控制，以实现对通过光线的光线强度的控制。现简要介绍本方案中利用的LCD多晶元板如下：
如图2所示，图2为一种示例性的液晶屏原理示意图。LCD液晶屏以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4a为另一种示例性的液晶屏原理示意图。图4b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4a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4b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。
本方案中，通过LCD多晶元板对通过的光线强度进行控制，具体控制方式依据确定出的光照调整策略。具体的，以光照调整策略包括背光拍照策略为例，首先识别出拍摄目标，再确定出拍摄目标对应的强光区域后，通过LCD多晶元板降低所述强光区域的光线通过率。该LCD多晶元板包含有多个像素控制单元，如图5所示，图5为本发明提供的一种LCD多晶元板的示意图，其中每个方格可通过控制信号进行单独的明暗透光控制，即对拍摄目标的附近区域的高亮度的方格降低其亮度。
本方案中，如图6和图7所示，图6为本方案实施例提供的一种LCD多晶元板、摄像头镜头以及图像传感器的位置关系示意图；图7为本方案实施例提供的另一种LCD多晶元板、摄像头镜头以及图像传感器的位置关系示意图。如图6所示，光线依次通过镜头、LCD多晶元板到达图像传感器；如图7所示，光线依次通过LCD多晶元板、镜头到达图像传感器。在一个实施例中，图像传感器采集得到的图像区域和LCD多晶元板的尺寸一致对应。
如图8所示，图8为本方案实施例提供的一种对不同波长情况下开态和关态的光透过率曲线示意图。其横坐标为不同光线的波长，纵坐标为开态和关态下相应的光线通过率。通过查询该曲线可以得到在开态的情况下400nm以上光线通过率良好，即可见光(400nm-700nm)以及近红外光(大于700nm)均可以通过；在关态的情况下，可见光的通过率几乎为0，而大于800nm的近红外光则可以正常的通过，实现近红外成像功能，因此，可以作为静态可控装置代替IR-CUT的机械式光谱切换功能。
由上述方案可知，本方案中的图像生成方法基于LCD多晶元板，该LCD多晶元板的厚度很低，且无需其他传统的马达、弹簧的控制，其中，所述LCD多晶元板设置于所述摄像头的镜头和图像传感器之间或所述摄像头的镜头设置在所述LCD多晶元板和所述图像传感器之间，通过确定当前图像生成场景下对应的光照调整策略，根据所述光照调整策略控制所述LCD多晶元板对通过的光线强度进行控制，使得调节后的光线通过图像传感器的感应以生成图像。本方案实现了对拍摄图像亮暗的动态调节，扩展了拍摄功能，能够得到效果更佳的图像，且便于安装。
在一个实施例中，可以根据用户手动设置的光线通过率和/或蒙板信息控制所述LCD多晶元板对通过的光线强度进行控制。
在一个实施例中，蒙板信息为包含包含晶元的光线通过率信息的数组，其中还包括起始位置、长度、宽度、数据大小以及整体透光度等信息，示例性地，光线通过率可以用0.0-1.0或0-255表示。示例性地，蒙板信息按照生成图像的比例转换为灰度图并与生成图像对齐，则通过蒙板信息中光线通过率信息的数组可以确定蒙板的位置、形状、大小以及每个晶元光线通过率等信息。
图9为本发明实施案例提供的另一种基于LCD多晶元板的图像生成方法的流程图，给出了一种具体的根据所述光照调整策略控制所述LCD多晶元板对通过的光线强度进行控制的方法。如图9所示，具体流程如下：
步骤S201、接收光线通过率控制。
步骤S202、确定当前拍摄画面的整体光线强度，通过所述LCD多晶元板降低整体光线通过率，使得调节后的光线通过图像传感器以生成图像。
针对外部指令，当接收确定的光线通过率的时候，根据所述光线通过率确定对应晶元的调节电压，控制晶元的电压为对应的调节电压，从而实现外部控制摄像头的光线通过率。进一步设计，采用可见光和近红外的双通截止滤 光片，即同时允许波长为400nm-700nm的可见光以及波长为800nm、820nm、850nm、920nm和/或940nm的近红外光线通过，当用户手动设置的光线通过率为0的时候，可见光的通过率为0％，而近红外光通过良好，则所生成为近红外图像，从而实现近红外光成像功能，可以作为静态可控装置代替IR-CUT的机械式光谱切换功能。
图10为本发明实施例提供的另一种基于LCD多晶元板的图像生成方法的流程图，给出了一种具体的根据所述光照调整策略控制所述LCD多晶元板对通过的光线强度进行控制的方法。如图10所示，具体流程如下：
步骤S301、接收蒙板信息控制。
步骤S302、确定蒙板信息对应LCD多晶元板的各晶元的光线通过率，通过所述LCD多晶元板各晶元的光线通过率，使得调节后的光线通过图像传感器以生成图像。
当接收确定的蒙板信息的时候，根据蒙板信息中各个象素点的灰度信息确定LCD多晶元板对应晶元的光线通过率，根据所述各晶元光线通过率确定对应晶元的调节电压，控制晶元的电压为对应的调节电压，从而实现外部控制摄像头的光线通过率。可以针对阳光直射、远光灯、背光等各种光照模式实现控制整体光照亮度、部分遮挡等功能，让图像生成装置可以适应各种光照环境。
图11为本发明实施例提供的另一种基于LCD多晶元板的图像生成方法的流程图，给出了一种具体的根据所述光照调整策略控制所述LCD多晶元板对通过的光线强度进行控制的方法。如图11所示，具体流程如下：
