Description

光源系统、投影设备及图像显示控制方法 技术领域
本发明涉及一种光源系统、投影设备及可用于投影设备的图像显示控制方法。
背景技术
目前，在显示(如投影领域)以及照明领域都开始越来越广泛的应用激光源，由于具有能量密度高，光学扩展量小的优势，在高亮度光源领域，激光源已经逐渐取代灯泡和LED光源。而在这其中，采用第一光源激发荧光粉产生所需光线(如蓝光激光激发黄色荧光粉产生白光或特定颜色的光)的光源系统，以其光效高、稳定性好、成本低等优点成为应用的主流。
特别是在投影技术中，以空间调制器的数量主要分为单片式系统和三片式系统，在单片式系统中，光源需要时序地提供RGB三种颜色的光进行照明，最终在屏幕上呈现出彩色的画面。而在三片式系统中，光源需要提供白光源，并在光机中进行分光，分别照射三片空间调制器，最终合光在屏幕上呈现出彩色的画面。在使用激光作为光源的三片式投影技术中，采用蓝光激光作为激发光源激发黄色荧光粉产生的白光源，以其光效高、稳定性好、成本低等优点成为应用的主流。
在光源系统构成中，可以采用区域镀膜的形式，在区域镀膜处透射或者反射蓝光，激发黄色荧光粉后产生蓝光+黄光得到的白光，经收集的白光经过区域镀膜，部分蓝光会损失，最终形成的白光束角方向上中心缺少蓝光，在应用中会对光束的质量造成影响。请参阅图1及图2，图1是一种现有技术的光源系统100的结构示意图，图2是图1所示的光源系统100的区域分光片106的结构示意图。所述光源系统包括激发光源101、匀光装置103、区域分光片106、收集透镜104、 散射粉片105、中继透镜107及方棒108。
具体地，所述激发光源101一般为蓝光激光光源，其发出激发光束经过所述匀光装置103匀光后，通过所述区域分光片106，如图2所示，所述区域分光片106中心区域镀膜为透蓝镀膜，区域外为反射镜。所述激发光经过所述收集透镜104收集后入射到所述散射粉片105上，所述激发光经过所述散射粉片105散射后以朗伯光的形式反射，在散射的过程中存在5％左右的散射粉片的自吸收损失，反射的激发光光经所述收集透镜104收集后出射，由于所述收集透镜104的大小有限，因此无法将郎伯发散的光线完全收集，存在5％～10％的损失。所述激发光进一步在所述区域分光片106处被反射，所述激发光在所述中心区域处会透射而损失掉8％～10％的能量(即区域损失)，造成所述光源系统100的光利用率较低。此外，经过所述中继透镜107成像到所述方棒108入口，最终从所述方棒108出口出射。由于入射到所述方棒108的光束中，由于上述区域损失的存在，光束中心部分缺少蓝色激发光，因此，在从方棒108出口出射的光存在颜色不均匀的现象。综上所述，在现有的光源系统100中，激发光(即蓝色光)的利用率较低，有散射粉片105自吸收损失、收集效率的损失以及区域镀膜的损失，并且区域镀膜损失对光源系统的均匀性也造成影响。

具体地，所述合光装置212还包括引导元件212a，所述引导元件212a将所述激发光源201发出的激发光引导(如反射)至所述合光元件212b，所述合光元件218还接收所述辅助光源202发出的所述红外光，从而所述红外光与所述激发光在所述合光元件218处合光。可以理解，所述引导元件212a可以为反射元件，如反射镜，所述合光元件212b可以合光膜片。可以理解，在变更实施方式中，在不需要红外光的光源系统100及投影设备中，所述辅助光源202及所述合光装置212均可以被省略。

请参阅图4，图4是图3所示光源系统200的区域分光装置205的平面结构示意图。所述区域分光装置205包括第一区域205a与第二区域205b，所述第一区域205a位于所述匀光器件204发出的所述激发光及所述红外光所在的光路上，所述区域分光装置205的第一区域205a将所述激发光引导(如透射)至所述波长转换装置207，其中所述激发光沿预定角度(如30度的入射角)倾斜入射至所述波长转换装置207。具体地，所述区域分光装置205可以为分光膜片(如二向色片)，所述分光膜片相较于所述激发光的方向大致呈45度放置。平面上，所述分光膜片可以大致呈矩形，所述第二区域205b可以位于所述第一区域205a的外围，具体地，所述第一区域205a可以位于所述区 域分光装置205的一侧，大致位于所述区域分光装置205的中心与所述区域分光装置205其中一侧边(如下侧边)的中央位置。所述第一区域205a为可透射激发光及红外光的镀膜区域，所述第一区域205a还可以反射波长长于所述激发光及所述红外光的其他光，如红色光、绿色光、黄色光。所述第二区域205b为可以反射激发光及其他光(如红色光、绿色光、黄色光)的镀膜区域。
所述第一收集系统206a位于所述区域分光装置205及所述波长转换装置207之间，用于对所述区域分光装置205及所述波长转换装置207之间的光进行汇聚、收集处理。具体地，所述第一收集系统206a可以包括收集透镜，如凸透镜。所述第一收集系统206a可以邻近所述波长转换装置207设置，且所述第一区域205a发出的激发光及所述红外光的光路相较于所述第一收集系统206a的光轴平行但是具有预定距离，从而所述第一收集系统206a对所述激发光及所述红外光进行收集后使得所述激发光及所述红外光沿所述预设角度入射至所述波长转换装置207。
请参阅图5，图5是图3所示光源系统200的波长转换装置207及散射装置210的结构示意图。所述波长转换装置207包括反射区域215及转换区域214，所述反射区域215与所述转换区域214可以为圆周方向依序设置的分段区域，所述光源系统200工作时，所述波长转换装置207沿圆周方向转动使得所述反射区域215与所述转换区域214依序位于所述第一收集系统206a发出的所述激发光所在的光路上。所述第一区域205a透射的激发光可以沿所述预定角度(如较小的角度：30度)倾斜入射至所述反射区域213及所述转换区域214。按照入射到不同区域的激发光做划分，所述激发光包括入射到所述反射区域215的第一部分激发光及入射到所述转换区域214的第二部分激发光。其中，可以理解，由于所述波长转换装置207沿圆周方向转动，所述第一部分激发光与所述第二部分激发光是分时提供到所述反射区域215与所述转换区域214的。
所述反射区域215可以包括具有反射材料的镜面反射表面，用于 将所述第一部分激发光及所述红外光反射，由于所述第一部分激发光及所述红外光沿所述预定角度倾斜入射至所述反射区域215，使得所述反射区域215对所述第一部分激发光及所述红外光进行镜像对称角度的反射后，所述第一部分激发光及所述红外光的光路相较于入射光路发生了偏移，从而所述第一部分激发光及所述红外光从所述波长转换装置207反射回所述区域分光装置205的区域205a’(即所述第二区域205b)与所述激发光及所述红外光的入射区域(即所述第一区域205a)是不同的，进而在不增加额外元件的情况下可以避免所述入射区域(即所述第一区域205a)产生的损耗，提高所述光源系统200的光利用率。
所述转换区域214可以包括设置有荧光材料与散射粉的反射表面，用于接收所述第二部分激发光、并将所述第二部分激发光转换为受激光、以及将所述受激光反射至所述波长转换装置。其中，所述受激光与所述辅助光的光谱不重合，本实施方式中，所述转换区域214的数量为三个，分别为第一转换区域214a、第二转换区域214b及第三转换区域214c，每个转换区域214用于产生一种颜色的受激光，所述受激光包括第一受激光、第二受激光及第三受激光。具体地，所述第一转换区域214a设置有第一荧光材料，如红色荧光材料，用于接收所述第二部分激发光并产生所述第一受激光(如红色受激光)。所述第二转换区域214b设置有第二荧光材料，如绿色荧光材料，用于接收所述第二部分激发光并产生所述第二受激光(如绿色受激光)。所述第三转换区域214c设置有第三荧光材料，如黄色荧光材料，用于接收所述第二部分激发光并产生所述第三受激光(如红色受激光)。本实施方式中，所述第一转换区域214a、所述第二转换区域214b、所述第三转换区域214c及所述反射区域215为沿圆周方向首尾相接设置的四个分段区域。如前所述，所述激发光、所述第一受激光及所述第二受激光分别为红绿蓝三基色光，所述第三受激光为第四颜色光，如黄色光。
其中，所述转换区域214产生的受激光以朗伯光的形式反射射出，即以较大的光束孔径出射，而所述反射区域215反射的所述第一部分 激发光及所述红外光由于由小角度入射而也以小角度反射，使得所述转换区域214发出的受激光的光路与所述反射区域215发出的第一部分激发光及所述红外光的光路不同，其中所述受激光的光路的孔径较大，位于所述第一部分激发光及所述红外光的外围。进一步地，所述波长转换装置207的反射区域215反射的所述第一部分激发光及所述红外光经由所述第一收集系统206a透射与收集后被引导至所述区域分光装置205的第二区域205b。所述第二区域205b为反射所述激发光(如反射蓝色光)的区域，故，所述第二区域205b将所述波长转换装置的反射区域215反射的所述第一部分激发光引导(如反射)至出光通道216。所述波长转换装置207的转换区域214发出的所述受激光经由所述第一收集系统206a透射与收集后被引导至所述区域分光装置205，其中由于所述受激光的光路的孔径较大，故所述受激光还入射至所述区域分光装置205的所述第一部分激发光及所述红外光入射区域的外围，所述区域分光装置205还将所述受激光引导(如反射)至所述出光通道216。其中，所述受激光在所述出光通道216中的光路通道将所述第一部分激发光及所述红外光在所述出光通道216中的光路通道包围，从而所述光源系统200的出光通道216的空间可以相对较小，改善出光通道空间较大造成的光源系统体积较大不利于小型化微型化等问题。

步骤S3，基于图像显示数据信号对所述第一颜色光进行图像调制产生第一颜色图像光。
步骤S4，基于图像显示数据信号对所述第二颜色光进行图像调制产生第二颜色图像光。
步骤S5，基于图像显示数据信号对所述第三颜色光进行图像调制产生第三颜色图像光。
步骤S6，基于图像显示数据信号对所述红外光进行图像调制产生红外图像光。
进一步地，在一种实施方式中，当所述步骤S2进一步包括提供所述第四颜色光的步骤，所述图像显示控制方法还可以进一步包括步骤S7：基于图像显示数据信号对所述第四颜色光进行图像调制产生第四颜色图像光。
具体地，所述方法中，所述步骤S3至S7可以由所述光调制模块240完成。所述光调制模块240可以基于所述第一颜色数据信号对所述第一颜色光及红外光进行图像调制产生第一颜色图像光、基于所述第二颜色数据信号对所述第二颜色光进行图像调制产生第二颜色图像光、基于所述第三颜色数据信号对所述第三颜色光进行图像调制产生第三颜色图像光、基于所述第四颜色数据信号对所述第四颜色光进行图像调制产生第四颜色图像光。

与现有技术相比较，所述光源系统200及投影设备220中，所述区域分光装置205控制所述激发光经由所述第一区域205a沿预定角度倾斜入射至所述反射区域215及所述转换区域214，所述反射区域215将所述第一部分激发光反射至所述第二区域205b，以使所述第二区域205b将所述第一部分激发光引导至所述出光通道216，由于经所述反射区域215反射后，所述第一部分激发光的光路相较于入射光路发生了偏移，从而所述第一部分激发光从所述波长转换装置207返回至所 述区域分光装置205的区域205a’与所述激发光的入射区域(第一区域205a)是不同的，进而在不增加额外元件的情况下可以避免所述入射区域产生的损耗，提高所述光源系统200的光利用率。
具体来说，在现有的光源中，蓝色激发光经过波长转换装置207表面散射粉散射，与其他受激光通过扩展量合光，由于存在散射粉的吸收、收集透镜的收集效率损失、区域镀膜的损失，效率最高只能达到60％。在本发明中，第一部分激发光(如蓝色激光)与红外光的光路与受激光(如红绿黄等其他颜色的光)在所述出光通道216中走不同的光路，第一部分激发光的光束角度非常小，在所述波长转换装置207的反射区域215的表面镜面反射，没有反射率和收集效率的损失，在入射到所述区域分光装置205的表面时可以被完全反射，效率非常高，可以达到80％以上，相对于现有光源提高了33％，从而对光源系统200发出的光的颜色有很大的提升。而红外光与第一部分激发光的光路相同，效率可以做到与激发光效率相同甚至更高。其他受激光(除了红色受激光在第三区域205c有少量透射损失外)，如对亮度起主要作用的绿色光，因为没有区域镀膜，效率可以提高8％。综合上述优点，本发明提供的光源系统200是一种高效的光源。

进一步地，所述投影设备320及其图像显示控制方法中，所述光调制模块240在所述第一子帧图像调制时段T1基于第二颜色数据信号对所述第一受激光进行图像调制产生第二颜色图像光、在所述第二子帧图像调制时段T2基于红外数据信号对所述红外光进行图像调制产生红外图像光、在所述第三子帧图像调制时段T3基于第三颜色数据信号对所述第三颜色光进行图像调制产生第三颜色图像光、及在所述第四子帧图像调制时段T4基于第一颜色数据信号对所述第一部分激发光进行图像调制产生第一颜色图像光及红外图像光。其中所述红 外数据信号可以是所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号中任意一个数据信号。本实施方式中，主要以所述红外数据信号为第三颜色数据信号(即绿色数据信号)进行说明。
可以理解，所述光调制模块340的控制器342还可以产生光源控制信号至所述光源系统300，用于控制光源系统300发出的三种颜色光及红外光的时序，使得所述光源系统300发出的光的时序与所述调制器343的图像调制时序一致。另外，可以理解，本实施方式的投影设备的光调制模块340为单片式DMD模块，并且所述光调制模块340要求支持RGBY信号，其中红外数据信号接入DDP的Y通道，如图11所示。在这种情况下，由于控制器342的DDP处理的特性，只有在显示静态图像时，才能够显示红外光图像。
请参阅图12，图12是本发明第三实施方式的投影设备420的结构示意图。所述投影设备420与第二实施方式的投影设备320的结构基本相同，也就是说，上述对所述投影设备320的描述基本上可以应用于所述投影设备420，二者的差别主要在于：光调制模块440的结构有所不同。具体地，所述光调制模块440包括第一调制模块441a及第二调制模块441b，所述第一调制模块441a用于对所述第一部分激发光及第二受激光进行图像调制，所述第二调制模块441b用于对所述第一受激光及所述红外光进行图像调制。其中每个调制模块441都包括控制器442(如DDP)与调制器443(如DMD)。所述第一调制模块441a的控制器442接收第一颜色数据信号及第三颜色数据信号，所述第一调制模块441a的控制器442基于所述第一颜色数据信号及第三颜色数据信号产生第一时序控制信号控制所述第一调制模块441a的调制器443，使得所述第一调制模块441a的调制器443基于所述第一时序控制信号调制所述第一部分激发光及所述第二受激光产生所述第一颜色图像光及所述第三颜色图像光。所述第二调制模块441b的的控制器442接收第二颜色数据信号及红外数据信号，所述第二调制模块441b的的控制器442基于所述第二颜色数据信号及红外数据信号产生第二时序控制信号控制所述第二调制模块441b的调制器443，使得 所述第二调制模块441b的调制器443基于所述第二时序控制信号调制所述第一受激光及所述红外光产生所述第二颜色图像光及所述红外图像光。本实施方式中，所述控制器442为支持RGB信号的DDP控制器，每个控制器442包括RGB三个信号输入通道。所述第一调制模块441a的控制器442的三个信号输入通道中的其中两个通道(如R通道与G通道)可以接收所述第三颜色数据信号(如绿色数据信号)，另外一个通道(如B通道)可以接收所述第一颜色数据信号(如蓝色数据信号)。所述第二调制模块441b的控制器442的三个信号输入通道中的其中两个通道(如R通道与G通道)可以接收所述第二颜色数据信号(如红色数据信号)，另外一个通道(如B通道)可以接收所述红外数据信号。其中所述红外数据信号可以采用所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号中的任意一个数据信号，本实施方式主要以所述红外数据信号采用第三颜色数据信号为例进行说明。
所述第三实施方式中，所述投影设备420采用双片式DMD调制模块，每个调制器443要求可处理RBG信号即可，这样使得红外数据信号可以与其他三种颜色数据信号(如蓝色、红色、绿色数据信号)相互独立，互不干扰。
请参阅图13，图13是本发明第四实施方式的投影设备520的结构示意图。所述投影设备520与第三实施方式的投影设备420的结构基本相同，也就是说，上述对所述投影设备420的描述基本上可以应用于所述投影设备520，二者的差别主要在于：数据处理模块530有所不同，其中红外数据信号采用基于第一颜色数据信号、第二颜色数据信号及第三颜色数据信号计算获得的数据信号。具体来说，所述数据处理模块530还包括信号处理单元534，所述信号处理单元534接收信号解码单元532输出的第一颜色数据信号、第二颜色数据信号及第三颜色数据信号，并基于所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号计算获得所述红外数据信号，即所述红外数据信号为所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信 号的复合信号。设所述第一至第三数据信号中任意一个像素的信号值为A、B、C，所述任意一个像素的红外数据信号的信号值IR符合如下公式：
IR＝(A*a+B*b+C*c)/Ymax；
其中所述a、b、c分别代表提供到光调制模块540的所述第一部分激发光、所述第一受激光及所述第二受激光的亮度，当所述任意一个像素中，所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号均为(255，255，255)，此时图像亮度最大，即图像最大亮度Ymax＝a+b+c。具体地，所述任意一个像素的红外数据信号的信号值IR可以为(A*a+B*b+C*c)/Ymax的结果取整，如四舍五入的方式取整。举例来说，若所述任意一个像素的第一、第二及第三颜色数据信号值为(50，60，80)，则此时所述任意一个像素的对应的红外数据信号的信号值应该为(50*a+60*b+80*c)/Ymax的结果取整。因此，本实施方式的投影设备中，可以通过这种算法对一幅图像的每一个像素点进行红外数据信号值的计算获得所述红外数据信号。
本实施方式中，由于所述红外数据信号为所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号的复合信号，使得红外光图像中每个像素值与所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号复合的黑白图像灰阶一致，这样红外光图像不会失真，即红外光图像得以保真。

本实施方式中，所述区域分光装置705包括分光片708及反射镜709，所述分光片708对应第一区域设置，所述反射镜709对应第二区域设置，所述第一区域的分光片708接收所述激发光并将所述激发光透射至波长转换装置707，所述波长转换装置707将所述第一部分激发光反射至所述反射镜709，所述反射镜709将所述第一部分激发光反射至第一出光通道716a，所述第一区域的分光片还将所述受激光反射至所述第一出光通道716a。具体地，所述反射镜709的反射表面为凹面，至少部分的所述受激光经所述反射镜709透射至所述分光片708，以使所述分光片708将所述波长转换装置707发出的受激光反射至所述第一出光通道716a。可以理解，所述反射镜709的凹面设计用于校正第一部分激发光(如蓝色光)与红外光的光程，用于与所述受激光的光程一致，从而提高入射至匀光装置711的光的均匀性。进一步地，引导装置712可以不设置曲面的反射镜，具体地，所述引导装置712可以为反射膜片，可以反射激发光、补充光、受激光及红外光，所述反射膜片接收所述第一出光通道716a的光并将所述第一出光通道716a的光反射至第二出光通道716b。
请参阅图17，图17是本发明第七实施方式的投影设备的光源系统800的结构示意图。所述光源系统800与第一实施方式的光源系统200的结构基本相同，也就是说，上述对所述光源系统200的描述基本上可以应用于所述光源系统800，二者的差别主要在于：区域分光装置805的结构不同。

请参阅图19，图19是本发明第九实施方式的投影设备的光源系统1000的结构示意图。所述光源系统1000与第一实施方式的光源系统200的结构基本相同，也就是说，上述对所述光源系统200的描述基本上可以应用于所述光源系统1000，二者的差别主要在于：区域分光装置1005、波长转换装置1007、散射装置1010的结构不同，从而出光通道1116也稍有不同。具体地，所述区域分光装置1005包括分光片1008及反射镜1009，所述分光片1008对应第一区域设置，所述反射镜1009对应第二区域设置，所述第一区域的分光片1008的第一表面接收所述激发光并将所述激发光反射至所述波长转换装置1007，所述波长转换装置1007将所述第一部分激发光反射至所述第二区域的反射镜1009，所述反射镜1009将所述第一部分激发光反射至所述第一区域的分光片1008的与所述第一表面相背的第二表面，所述第一区域的分光片1008的第二表面将所述第一部分激发光反射至所述出光通道1116，所述波长转换装置1007还将受激光反射至所述出光通道1116。所述区域分光装置1005还包括引导元件1113，所述引导元件1113将补充光源1003用于发出的补充光反射至所述波长转换装置1007，以使所述波长转换装置1007将所述补充光与所述受激光一起反射至所述出光通道1116。所述散射装置1110与所述波长转换装置1007是分体设置的两个独立元件，所述散射装置1110用于接收所述出光通 道116的光并将散射后光提供至匀光装置1111的入口，第三收集系统1006c用于对所述出光通道1116的光进行收集以使所述出光通道1116的光经由所述散射装置1110成像到所述匀光装置1111的入口。

请参阅图21与图22，图21是本发明第十一实施方式的投影设备1320的结构示意图，图22是图21所示投影设备1320的光源系统1300的发光时序图。所述投影设备1320与光源系统1300与第一实施方式的投影设备220与光源系统200的结构基本相同，也就是说，上述对所述投影设备220与光源系统200的描述基本上可以应用于所述投影设备1320与光源系统1300，二者的差别主要在于：光源系统1300的引导装置1308与红外光源1302、光源系统1300的发光时序、数据处理模块1330及光调制模块1340的控制及调制方式均有所不同。
具体地，所述红外光源1302邻近所述引导装置1308设置，所述 引导装置1308为分光膜片，其反射所述第一部分激发光、所述受激光但透射所述红外光源发出的红外光，具体地，所述引导装置1308可以反射可见光透射红外光。具体地，所述引导装置1308接收所述红外光，并将所述红外光透射至所述第二出光通道1316b，所述受激光在所述第二出光通道1316b中的光路通道将所述第一部分激发光与所述红外光在所述第二出光通道1316b中的光路通道包围，可见，本实施方式中，所述红外光不经过区域分光装置1305与波长转换装置1307，而是直接在第二出光通道1316b(即匀光装置1311的入口前)与其他光进行合光。所述光源系统1300还包括光源控制器1319，所述光源控制器1319用于控制所述红外光源1302的发光强度。
以下对所述投影设备1320的图像显示控制方法进行介绍，其中，可理解，以下主要对与第一实施方式中不同的部分进行介绍，相同的部分不再赘述。
具体地，光调制模块1340进行一帧图像的调制时段(即一个波长转换周期T)包括三个不同的时间段，分别为第一子帧图像调制时段T1、第二子帧图像调制时段T2、第三子帧图像调制时段T3，所述光调制模块1340在所述第一子帧图像调制时段T1基于所述第二颜色数据信号对所述第一受激光进行图像调制产生第二颜色图像光、在所述第二子帧图像调制时段T2基于所述第三颜色数据信号对所述第二受激光进行图像调制产生第三颜色图像光、在所述第三子帧图像调制时段T3基于所述第一颜色数据信号对所述第一部分激发光进行图像调制产生第一颜色图像光，所述光调制模块1340还在所述第一、第二及第三子帧图像调制时段T1、T2及T3(即整帧图像的调制时段T)基于所述红外数据信号对所述红外光进行图像调制产生红外图像光。
进一步地，数据处理模块1330将接收到的图像数据进行解码获得所述第一颜色数据信号、第二颜色数据信号及第三颜色数据信号，所述数据处理模块1330还基于所述第一至第三颜色数据信号计算红外数据信号，设所述第一至第三数据信号中任意一像素的信号值为A、B、C，提供到所述光调制模块1340的所述第一部分激发光、所述第 一受激光及所述第二受激光的亮度分别为a、b、c，所述光源控制器1319控制所述红外光的亮度使得提供到所述光调制模块1340的红外光在所述三个子帧图像调制时段的亮度分别为d、e及f，其中d＝α*a；e＝α*b；f＝α*c，即所述提供到所述光调制模块1340的红外光在所述三个子帧像调制时段T1、T2及T3的亮度分别为所述第一至第三颜色光的亮度的α倍，使得以上各参数能够满足以下公式：(A*a/255+B*b/255+C*c/255)＝α(A*d/255+B*e/255+C*f/255)，即(A*a+B*b+C*c)＝α(A*d+B*e+C*f)，从而使得产生的红外光图像与可见光图像的灰阶相匹配。
举例来说，设所述第一至第三数据信号中任意一像素的信号值A、B、C为(50，40，30)，则其预计亮度为Y＝50*a/255+40*b/255+30*c/255。若利用所述信号值(50，40，30)来控制红外光，为保证像素亮度不失真，需要保证像素实际亮度值Y’＝50*d/255+40*e/255+30*f/255，并且d＝αa，e＝αb，f＝αc，如此得到，所述实际像素亮度值Y’＝α(50*a/255+40*b/255+30*c/255)，即红外光对应的亮度为可见光的α倍，这样可使得每个像素的亮度值均为RGB可见光图像的α倍，因此可以利用光源控制器1319对红外光源进行控制，保持其在所述三个子帧像调制时段T1、T2及T3的亮度为d，e，f。
在一种实施例中，由于波长转换装置的绿光(即第二受激光)亮度＞红光(即第一受激光)亮度＞蓝光(即激发光)亮度，及b＞a＞c，所以所述光源控制器1319可控制所述红外光在波长转换装置转至绿光段时(即第二子帧图像调制时段)亮度L2最高，在蓝光段时(即第三子帧图像调制时段)亮度L3最低，在红光段时(即第一子帧图像调制时段)的亮度L1在L3与L2之间，即L3＜L1＜L2。
具体地，可以理解，所述光源控制器1319可以接收所述红外数据信号或者所述光调制模块1340的控制器基于所述红外数据信号产生的光源时序控制信号来控制所述红外光源1302的驱动电流来调节所述红外光的亮度。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围， 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
