本发明实施例提供了一种用于LED显示器的图像处理装置。
图4是根据本发明实施例的用于LED显示器的图像处理装置的示意图。如图4所示，该装置包括：处理器10和LED控制器20。
处理器10，用于接收原始图像数据，根据原始图像数据获取原始像素的信息，将原始像素的信息按照预设算法执行计算，得到目标像素的信息，其中，原始像素为在LED显示屏面板上按照预设规则分布的像素点，原始像素的信息包括原始像素的颜色信息和原始像素的位置信息，目标像素为不符合预设分布规则的像素，目标像素的信息包括目标像素的颜色信息和目标像素的位置信息。
由数字摄影设备拍摄图像视频资源，比如，通过数码相机、摄像机等拍摄图像视频资源，进而在LED显示屏上显示图像视频资源。
在由数字摄影设备拍摄图像视频资源之后，处理器10接收图像视频资源的原始图像数据。其中，处理器10为一种图像视频处理器；原始图像数据为图像视频资源的每一帧图像的数据，用于表征图像视频资源的信息，确定图像视频资源的最终显示效果。
由原始图像数据可以确定图像视频资源的原始像素，原始像素为在LED显示屏面板上按照预设规则分布的像素点，比如，原始像素为按照矩阵式分布的LED像素点。LED像素点随着LED显示屏面板上LED灯的变化而变化。在处理器10接收图像视频资源的原始图像数据之后，处理器10根据原始图像数据获取原始像素的信息。原始像素的信息包括原始像素的颜色信息和原始像素的位置信息。原始像素的颜色信息由三原色的级数来表示，比如，像素W1H1的颜色信息为(R，G，B)，其中，R原始像 素中表示红色的级数，G原始像素中表示绿色的级数，B表示原始像素中黑色的级数。原始像素的位置信息为原始像素在LED显示屏面板上的具体位置信息，可以由二维坐标系的横坐标和纵坐标来确定原始像素在LED显示屏面板的具体位置。原始图像数据包括组成图像视频资源的每一帧图像的多个原始像素，通过多个原始像素的颜色信息和位置信息共同确定原始图像在LED显示屏面板上的显示效果。
在处理器10根据原始图像数据获取原始像素的信息之后，处理器10将原始像素的信息按照预设算法执行计算，得到目标像素的信息。具体而言，目标像素为不符合预设分布规则的像素点，优选地，目标像素为不按照矩阵式分布的像素点，也即，目标像素的分布不具有横平竖直的特点。目标像素的信息包括目标像素的颜色信息和目标像素的位置信息。目标像素的信息包括目标像素的颜色信息和目标像素的位置信息。目标像素的颜色信息也由三原色的级数来表示，比如，目标像素W1′H1′的颜色信息为(R′，G′，B′)，其中，R′表示目标像素中红色的级数，G′表示目标像素中绿色的级数，B′表示目标像素中黑色的级数。目标像素的位置信息为目标像素在LED显示屏面板上的位置信息，可以二维坐标系的横坐标和纵坐标来确定目标像素在LED显示屏面板的具体位置。处理器10将原始像素的颜色信息通过预设算法计算为目标像素的颜色信息，将原始像素的位置信息通过预设算法计算为目标像素的位置信息。因此，原始像素和目标像素有一定的对应关系，由多个目标像素组合而成的图像与多个原始像素组合而成的图像表示同一图像。
LED控制器20，用于根据目标像素的信息控制原始图像数据对应的图像显示在LED显示屏面板上。
在处理器10将原始像素的信息按照预设算法执行计算之后，LED控制器20根据目标像素的颜色信息和目标像素的位置信息控制原始图像数据对应的图像显示在LED显示屏面板上。LED控制器可以将多个目标像素的信息转化为LED显示屏面板可以接收的信号，控制LED显示屏面板上多个LED灯的位置，进而使LED像素点在LED显示屏面板上成不符合预设规则的状态分布，得到多个目标像素。多个目标像素以各自的颜色信息对应的颜色呈现，而数字摄影设备中的感光像素颗粒为符合预设规则的矩阵式分布，从而不会因为光电衍射现象在生成的原始图像数据对应的图像上产生摩尔条纹。通过预设算法将原始像素对应的LED灯在LED显示屏面板上重新分布，从而得到不符合预设规则的LED像素点，进而提高了LED显示屏的显示图像的质量。

图5是根据本发明第一实施例的用于LED显示器的图像处理方法的流程图。如图5所示，该方法包括以下步骤：
步骤S501，接收原始图像数据。
原始图像数据为图像视频资源的每一帧图像的数据，用于表征图像视频资源的信息，比如，图像视频资源的颜色信息和位置信息等。通过原始图像数据确定图像视频资源的图像的颜色，图像的轮廓、图像的位置、图像的亮度、图像的清晰度等图像效果。原始图像数据的获取可以由数字摄影设备来获取，比如，通过数码相机、摄像机、手机的摄像装置等来获取原始图像数据。其中，数字摄影设备包括光学镜头、用于光电转化的感光器件、感光器件上的感光像素颗粒等，感光像素颗粒成矩阵式分布，具有横平竖直的特点。在通过数字摄影设备获取原始图像数据之后，可以通过图像视频处理器对原始图像数据进行接收。
步骤S502，根据原始图像数据获取原始像素的信息。
在接收原始图像数据之后，根据原始图像数据获取原始像素的信息。其中，原始像素为在LED显示屏面板上按照预设规则分布的像素点，原始像素的信息包括原始像素的颜色信息和原始像素的位置信息。具体而言，由原始图像数据可以确定图像视频资源的原始像素，也即，确定LED显示屏面板上LED像素点的信息。LED像素点的分布随着LED显示屏面板上LED灯的变化而变化，比如，LED显示屏面板上LED灯按照矩阵式分布，则在LED显示屏面板上分布的LED像素点与LED灯分布的方式相同，按照矩阵式分布，如图6所示。其中，图6是根据本发明实施例的原始像素按照矩阵式分布的示意图，601为LED显示屏面板，602为原始像素点。原始像素602按照矩阵式分布在LED显示屏面板602上，具有横平竖直的特点，与数字摄影设备的感光器件上的感光像素颗粒的分布方式相同。原始图像数据包括组成图像视频资源的每一帧图像的多个原始像素602，通过多个原始像素602的颜色信息和位置信息共同确定原始图像在LED显示屏面板上的显示效果。
在根据原始图像数据获取原始像素的信息之后，提取原始像素的颜色信息，原始像素的颜色信息用(R，G，B)表示，其中，R表示原始像素中红色的级数，G表示原始像素中绿色的级数，B表示原始像素中黑色的级数原始像素的位置信息用二维坐标系表示。图7是根据本发明实施例的原始像素的颜色信息的示意图。如图7所示，原始像素的位置信息通过原始像素在二维坐标系的横坐标pixel(W)和纵坐标pixel (H)来确定，每一格代表一个原始像素。比如，原始像素W1H1(R1，G1，B1)，原始像素W2H2(R2，G2，B2)，原始像素W3H3(R3，G3，B3)，原始像素W4H4(R4，G4，B4)等。
在根据原始图像数据获取原始像素的信息之后，提取原始像素的像素间距信息，优选地，从原始像素的位置信息中提取原始像素的像素间距信息，像素间距信息为用于表示相邻原始像素之间的间距的信息。
在根据原始图像数据获取原始像素的信息之后，确定原始像素移动到目标像素所需的偏移量，包括确定原始像素移动到目标像素所需的偏移量的大小和方向。优选地，偏移量包括横坐标偏移量和纵坐标偏移量。横坐标偏移量和纵坐标偏移量小于等于预设阈值，预设阈值小于原始像素的像素间距。图8是根据本发明实施例的原始像素偏移量的示意图。如图8所示，建立以原始像素为原点的二维坐标系，其中，801为原始像素的位置，也即，二维坐标的原点，802为目标像素的位置，803为以预设阈值R为半径的圆形区域，也即，允许原始像素偏移的偏移量的范围，预设阈值R小于原始像素的间距。原始像素包括多个原始像素，确定原始像素移动到目标像素所需的偏移量包括：分别确定多个原始像素移动到原始像素对应的目标像素所需的偏移量，得到多个偏移量。其中，多个偏移量的大小或者方向不同，多个偏移量决定目标像素的离散程度。
在根据原始图像数据获取原始像素的信息之后，提取原始像素的坐标信息。优选地，原始像素的坐标信息为原始像素的二维坐标信息，也即，原始像素的横坐标信息和原始像素的纵坐标信息。
步骤S503，将原始像素的信息按照预设算法执行计算，得到目标像素的信息。
在根据原始图像数据获取原始像素的信息之后，将原始像素的信息按照预设算法执行计算，得到目标像素的信息。其中，目标像素和原始像素通过预设算法有一定的对应关系，从而使多个目标像素组合而成的图像与多个原始像素组合而成的图像表示同一图像。优选地，将原始像素的颜色信息和原始像素的位置信息按照预设算法执行计算，得到目标像素的信息，目标像素的信息包括目标像素的颜色信息和目标像素的位置信息。
在提取原始像素的颜色信息、提取原始像素的像素间距信息以及确定原始像素移动到目标像素所需的偏移量之后，将原始像素的信息按照预设算法执行计算包括：将原始像素的颜色信息、原始像素的像素间距信息和偏移量通过预设算法执行计算，得到目标像素的颜色信息。图9是根据本发明第一实施例的原始像素与目标像素的示意图。如图9所示，原始像素为矩阵式分布，每一格代表一个原始像素。原始像素的像 素间距信息为像素间距p，将颜色信息为(R1，G1，R1)的原始像素的横坐标偏移x，将原始像素的纵坐标偏移y，从而得到如图9所示位置的目标像素，其颜色信息为(R1′，G1′，R1′)。可选地，目标像素的颜色信息(R1′，G1′，R1′)的具体算法为：
令K1＝x*(p-y)/(p*p)，K2＝x*y/(p*p)，K3＝y*(p-x)/(p*p)，则：
R1'＝R1*(1-K1-K2-K3)+R2*K1+R4*K2+R3*K3
G1'＝G1*(1-K1-K2-K3)+G2*K1+G4*K2+G3*K3
B1'＝B1*(1-K1-K2-K3)+B2*K1+B4*K2+B3*K3
该算法通过原始像素的像素间距信息和偏移量将将原始像素的颜色信息(R1，G1，R1)转化为目标像素的颜色信息(R1′，G1′，R1′)，从而实现了LED显示屏上原始像素的颜色信息随原始像素位置的改变而进行调整，进而提高了图像显示的质量。
在提取原始像素的坐标信息之后，将原始像素的信息按照预设算法执行计算还包括根据偏移量对原始像素的坐标信息进行偏移，也即，根据偏移量的大小和方向对原始像素的横坐标信息和纵坐标信息进行偏移，如图10所示。图10是根据本发明第二实施例的原始像素与目标像素的示意图，其中，1001为LED显示屏面板，1002为原始像素，1003为目标像素，多个原始像素1002偏移的方向和大小不同，多个原始像素偏移1002的方向和大小差距越大，目标像素1003的不规则分布程度就越大，从而使LED显示屏面板1001上的多个目标像素1003改变原始像素1002横平竖直的分布方式。图11是根据本发明第一实施例的目标像素的示意图。如图11所示，1101为LED显示屏面板，1102为目标像素，经过对原始像素进行偏移之后，目标像素1102为不按照预设规则分布的离散LED像素点。图12是根据本发明第二实施例的目标像素的示意图。如图12所示，目标像素为经过预设算法得到的在LED显示屏面板上呈现的大量不规则的离散LED像素点，从而避免了在图像显示时产生摩尔纹的现象，提高了图像显示的质量。
该实施例将原始像素经过预设算法计算，从而得到目标像素的颜色信息和经过预设算法偏移得到目标像素的位置信息，从而得到了目标像素的信息。
步骤S504，根据目标像素的颜色信息和目标像素的位置信息控制原始图像数据对应的图像显示在LED显示屏面板上。
将原始像素的信息按照预设算法执行计算之后，根据目标像素的颜色信息和目标像素的位置信息控制原始图像数据对应的图像显示在LED显示屏面板上。具体而言，根据目标像素的坐标信息控制LED显示屏面板上LED像素点的位置，根据LED像素 点的位置和目标像素的颜色信息在LED显示屏面板上显示图像。目标像素和原始像素通过预设算法有一定的对应关系，使多个目标像素组合而成的图像与多个原始像素组合而成的图像表示同一图像。
该用于LED显示器的图像处理方法的实施例通过接收原始图像数据，然后根据原始图像数据获取原始像素的信息，再将原始像素的信息按照预设算法执行计算，得到目标像素的信息，最后根据目标像素的颜色信息和目标像素的位置信息控制原始图像数据对应的图像显示在LED显示屏面板上，从而提高了LED显示屏的显示图像的质量。

原始图像数据的获取可以由数字摄影设备来获取，比如，通过数码相机、摄像机、手机的摄像装置等来获取原始图像数据。根据原始图像数据获取原始像素的信息。
步骤S1302，确定预设算法。
该预设算法可以将原始像素的颜色信息和原始像素的位置信息进行计算，获得目标像素，使得目标像素为不按照预设规则分布的离散LED像素点，同时对颜色进行调整。其中，原始像素为在LED显示屏面板上按照预设规则分布的像素，原始像素的信息包括原始像素的颜色信息和原始像素的位置信息，目标像素为不符合预设分布规则的像素，目标像素的信息包括目标像素的颜色信息和目标像素的位置信息。该预设算法通过软件嵌入到图像处理系统和LED控制器中，可以根据算法的改进而进行更新。
