本公开的实施例提供的显示装置，能够确定需要强调显示的图像位置，可以实现需强调显示部分的强调显示，提升显示效果，提升用户体验。
例如，第一图像0101示出的画面可如图11所示，以该画面为例进行说明，但第一图像0101显示的画面不限于图11所示，可显示任意画面。
根据本公开一实施例提供的显示装置，强调显示处理包括强调区10101(可参见图2)的颜色的调整。例如，强调区10101(可参见图2)的颜色的调整包括强调区10101底色的调整。例如，可在强调区10101内形成底色光斑。例如，强调区10101内形成的底色光斑可为预定颜色。例如，强调显示处理后，强调区10101内形成的底色光斑的颜色可为红、粉红、绿、黄等任选的颜色。例如，光斑可为圆形，但不限于此。对强调区的颜色进行调整的强调显示处理对应形成的第二图像0105中的强调显示部分10501可如图12所示。例如，强调区的底色是指强调区的显示内容(例如文字或图片)的背景色。
根据本公开一实施例提供的显示装置，强调显示处理包括在强调区10101(可参见图2)外边缘形成边框。在强调区外边缘形成边框的强调显示处理对应形成的第二图像0105中的强调显示部分10501可如图13所示。
根据本公开一实施例提供的显示装置，强调显示处理可包括在强调区10101(可参见图2)外边缘形成边框和在强调区10101内形成底色光斑。强调显示处理后对应形成的第二图像0105中的强调显示部分10501可如图14所示。
根据本公开一实施例提供的显示装置，为了观众更加容易的观看到强调显示部分10501的位置，强调显示处理还可包括将边框或底色光斑闪烁显示。
除了将底色光斑进行预定颜色的调整外，还可以根据第一图像0101中强调区10101中的显示内容进行底色光斑的颜色调整。
根据本公开一实施例提供的显示装置，强调区10101底色的调整包括将强调区10101内的底色调整为强调区10101内主色调的互补色，或调整为强调区10101内的主体显示色与主色调的互补色之间的颜色。
图15为本公开另一实施例提供的一种显示装置的示意图。根据本公开一实施例提供的显示装置，如图2和图15所示，还包括主色调确定部107，主色调确定部107被配置来确定强调区10101的至少一部分区域的主色调。例如，强调区10101的至少一部分区域可被称作主色调判断区A0(可参见图2)。主色调判断区A0的面积可等于或小于强调区10101的面积。例如，主色调判断区的面积的确定可根据强调区10101内显示的内容而定。以下以强调区10101即为主色调判断区为例进行说明。
根据本公开一实施例提供的显示装置，如图16所示，主色调确定部107可包括主色调判断区确定单元1071、颜色获取单元1072、颜色分析单元1073和颜色分析结果输出单元1074。
图17示出了主色调确定部107的工作流程。例如，如图17所示，主色调判断区确定单元1071可被配置来确定主色调判断区，即确定主色调判断区的位置。颜色获取单元1072可被配置来分别统计主色调判断区(强调区的至少一部分区域)的同一颜色的所有子像素的灰度值，颜色分析单元1073被配置来分别计算主色调判断区(强调区10101的至少一部分区域)各不同颜色的子像素的灰度值的平均值，并根据各不同颜色的子像素的灰度值的平均值 合成一个颜色值作为主色调，颜色分析结果输出单元1073被配置来输出强调区的主色调。
例如，主色调判断区的主色调可包括主色调判断区的主体显示色、主色调判断区的多种主体显示色中的一种、或者主色调判断区的多种主体显示色的合成色，但不限于此。
例如，主色调确定部107可将强调区的主色调发送给图像处理部104(可参见图6)。请结合图2、图6、图11和图12，图像处理部104可根据强调区10101的主色调来确定强调显示部分10501的主色调。
主色调确定部107的功能也可以通过一台计算机实现或多台计算机分别实现，该计算机可以是通用计算装置或专用计算装置。
根据本公开一实施例提供的显示装置，如图18所示，主色调判断区(例如，需要突出显示的位置)的颜色判断如下：
首先判断强调区是否有文字。
若强调区有文字，则认为演讲者需要对文字部分突出强调，考虑到文字和底色一般为互补色，所以强调色选取为文字颜色和底色之间的颜色。之后可将强调区除了文字之外的区域调整为强调色，或者，将强调区除了文字之外的区域显示为强调色和原画面的叠加。
若强调区没有文字，则说明演讲者需要对强调区的图进行强调显示，因此可先判断画面的主色调，再确定强调色为与强调区主色调的互补色。
例如，第二图像0105中强调显示部分10501的显示画面为第一图像中强调区的画面与强调画面(强调色)的叠加。
例如，叠加比例为：第一图像中强调区的画面的色调在强调显示部分10501的画面的颜色占比为30％-50％。
例如，第一图像0101中强调区10101的画面的主色调的判断方法为：
首先，确定需要做出判断主色调的区域在整个第一图像中的范围，定义为主色调判断区。例如，主色调判断区的确定方式可如前所述。
统计主色调判断区所有的同一颜色的子像素的灰度值(不是单个子像素的灰度值)。
分别计算主色调判断区所有的不同颜色的子像素的灰度值的平均值，例如，分别计算主色调判断区红色(R)、绿色(G)和蓝色(B)子像素的灰 度值的平均值，例如计算主色调判断区所有R像素灰度值的平均值，计算主色调判断区所有G像素灰度值的平均值，计算主色调判断区所有B像素灰度值的平均值。
使用计算得到的R、G和B子像素的灰度值的平均值合成为一个颜色值(三原色合成一种颜色)，该颜色值即为主色调判断区的主色调。
本公开的实施例以三原色为红绿蓝为例进行说明，子像素也可采用其他颜色，本公开的实施例对此不作限定。
例如，可先判断强调区10101的主体显示色，再使用主体显示色的互补色做底色突出显示。图19示出了色相环。互补色的定义为：如果两种颜色混合后形成中性的灰黑色，那么这两种颜色为补色(Complementary Colors)，色相环(如图19所示)上相距180°的色相为互补色。互补色有如下特性：两个互补的颜色靠近放置在一起时，它们各自的色彩都在视觉上加强了饱和度，显得色相、纯度更强烈，这是由于人的眼睛对色彩需求的一种生理的平衡，看到任何一种颜色时，总是要求它的相对补色，因此，在看到两个互补色并列时，二者彼此交接的边缘分别引发出各自的补色，从而在视觉上加强了两种色彩的颜色。因此，通过将强调区(突出显示位置)的颜色设置为强调区主色调的互补色，使得观众能够更加轻松、清楚地看到演讲者需要强调的内容。
例如，互补色的实现方式如下：
颜色获取单元1072可被配置来获取主色调判断区(强调区的至少一部分区域)的位置，颜色分析单元1072可被配置来分析主色调判断区的主色调，确定互补色，颜色分析结果输出单元1073被配置来输出强调区的主色调的互补色。颜色分析结果输出单元1073可将强调区的主色调的互补色信号发送至图像处理部104。图像处理部104合成需要显示的第二图像信号。
例如，当颜色分析单元1072分析出主体显示色为多种时，颜色分析单元1072还能分析显示画面的底色和内容色，比如白色底色配黑色字体。这时突出显示颜色可选取二者之间颜色作为互补色。或者判断某一种颜色面积占比较大如80％，则取该颜色的互补色作为突出显示的颜色。
本公开一实施例可通过在第一显示部中添加指示信号接收器，可以实时检测用户对显示图像的指示位置，同时强调区确定部对接收到的位置信号做 处理之后，确定需要重点突出的位置(确定强调区)，并可根据指示位置和显示的内容的颜色形成第二图像的信号，以实现强调/突出显示。例如，通过将突出显示位置的颜色设置为需要加强位置的互补色，使得观众能够更加轻松、清楚地看到演讲者需要强调的内容。例如，可选取合适的突出颜色的底色，不影响其他位置处的图像的显示。
本公开的实施例提供的显示装置，可选取合适的强调色，不影响图像的显示。
根据本公开一实施例提供的显示装置，强调区10101的面积与第一图像0101的面积的比值等于强调显示部分(强调显示区)10501的面积与第二图像0105的面积的比值。例如，强调区10101的面积与非强调区10102的面积的比值等于强调显示部分(强调显示区)10501与非强调显示部分(非强调显示区)10502的面积的比值。例如，强调显示部分10501与非强调显示部分/非强调显示区10502形成一个完整的第二图像105，强调显示部分10501在强调处理过程中只是颜色被调整。当第二显示部的尺寸大于第一显示部的尺寸时，虽然第二图像0105的尺寸大于第一图像的尺寸，但其并非源于强调显示处理过程中对于信号的调整。
本公开至少一实施例提供一种显示方法，包括：利用第一显示部101显示第一图像0101；指示点1061被投射在第一图像0101上，获取指示点1061在第一图像0101区域内的位置；根据所述指示点1061在第一图像0101区域内的位置确定强调区10101；基于所述第一图像0101的信号进行强调区10101的强调显示处理以形成第二图像0105的信号，并输出第二图像0105的信号。
根据本公开一实施例提供的显示方法，还可以包括利用第二显示部105接收所述第二图像0105的信号，以形成包括强调显示部分10501的第二图像0105。
例如，演讲者可以使用激光指示器的激光指向第一显示部，且第一显示部能够接收激光指向第一图像的位置信息，将位置信息传递给计算机，计算机的强调区确定部被配置来确定位置信息与第一图像的关系，图像处理部根据第一图像信号和指示点位置信息合成包括强调显示部分的第二图像信号。从而，可将需要强化突出显示的位置突出显示(强调显示)。
