具体实施方式detailed description

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

在本发明实施中，用户设备(User Equipment，简称“UE”)，也称为终端(Terminal)。该终端对逐帧输出的显示图像进行图像处理，在每帧的显示图像上叠加遮挡图案。连续帧中的遮挡图案按照一定的顺序变化，终端逐帧输出叠加遮挡图案后的显示图像。依据终端输出图像的频率，在某一瞬间，显示图像是无法完整显示的，但结合视觉停留原理，用户可以看到完整的显示图像。在本发明实施例中，终端可以为手机，平板电脑、电视等具有显示器的设备。In the implementation of the present invention, a user equipment (User Equipment, referred to as "UE") is also called a terminal (Terminal). The terminal performs image processing on the display image outputted frame by frame, and superimposes the occlusion pattern on the display image of each frame. The occlusion patterns in consecutive frames are changed in a certain order, and the terminal outputs the display image after the occlusion pattern is superimposed frame by frame. According to the frequency of the output image of the terminal, at a certain moment, the display image cannot be completely displayed, but in combination with the principle of visual pause, the user can see the complete display image. In the embodiment of the present invention, the terminal may be a device with a display such as a mobile phone, a tablet computer, or a television.

为便于说明，下面结合图1对本发明实施例的技术方案进行详细的说明。应理解，这仅是用以说明本发明实施例的技术方案的一个例子，并不对本发明实施例构成任何的限定。For convenience of description, the technical solution of the embodiment of the present invention will be described in detail below with reference to FIG. 1 . It should be understood that this is only an example of the technical solution of the embodiments of the present invention, and is not intended to limit the embodiments of the present invention.

图1是本发明实施例图像处理方法的示意流程图。如图1所示的图像处理方法100的执行主体为终端，该方法100包括：FIG. 1 is a schematic flow chart of an image processing method according to an embodiment of the present invention. The execution body of the image processing method 100 shown in FIG. 1 is a terminal, and the method 100 includes:

110，逐帧接收显示图像；110. Receive a display image frame by frame;

120，确定每帧显示图像的遮挡图案，遮挡图案遮挡显示图像的一部分；120, determining an occlusion pattern of the image displayed in each frame, the occlusion pattern occluding a portion of the display image;

130，逐帧输出图像，输出图像为显示图像与所述显示图像对应的遮挡图案的叠加。130. Output an image frame by frame, and output the image as a superposition of the occlusion pattern corresponding to the display image and the display image.

终端按预设帧率逐帧接收显示图像。终端按预设帧率逐帧输出图像，每一个输出图像以N帧连续输出。N帧连续输出的输出图像中的显示图像是相同的。每帧显示图像的每个像素在N帧连续输出的输出图像中至少出现一次未被遮挡图案遮挡。N帧连续输出的输出图像中，每帧遮挡图案未遮挡部分的显示图像满足视觉停留原理。N取正整数。The terminal receives the display image frame by frame at a preset frame rate. The terminal outputs images frame by frame at a preset frame rate, and each output image is continuously output in N frames. The display images in the output image continuously outputted by the N frames are the same. Each pixel of the image displayed per frame is at least in the output image continuously outputted in N frames It is now blocked by an occlusion pattern. In the output image in which the N frames are continuously output, the display image of the unoccluded portion of each frame of the occlusion pattern satisfies the principle of visual pause. N takes a positive integer.

具体的，在本发明实施例中，终端按照预设帧率输出图像。终端对每帧显示图像叠加所述显示图像对应的遮挡图案。显示图像与显示图像对应的遮挡图案叠加合成为输出图像。每帧显示图像对应的遮挡图案只遮挡该帧显示图像的部分像素。每帧显示图像的每个像素在N帧连续输出的输出图像中至少有一次未被遮挡图案遮挡。当预设帧率满足用户视觉停留的时间，连续N帧输出图像时，结合视觉停留原理或者说视觉滞留原理，用户可以在看到下一帧输出图像时，上一帧输出图像还保留在用户的视线中，用户可以看到完整的显示图像。Specifically, in the embodiment of the present invention, the terminal outputs an image according to a preset frame rate. The terminal superimposes the occlusion pattern corresponding to the display image on each frame display image. The occlusion pattern superimposed on the display image and the display image is superimposed into an output image. The occlusion pattern corresponding to each frame display image only blocks part of the pixels of the frame display image. Each pixel of the image displayed per frame is occluded by the occlusion pattern at least once in the output image continuously outputted by N frames. When the preset frame rate satisfies the time of the user's visual pause, when the image is output in consecutive N frames, combined with the principle of visual pause or the principle of visual detention, the user can keep the image of the previous frame while the next frame is output. In the line of sight, the user can see the complete display image.

其中，不同帧的遮挡图案可以是不同的，可以按照一定的顺序变化。The occlusion patterns of different frames may be different and may be changed in a certain order.

在110中，显示图像可以为终端需要输出的显示图像。终端逐帧接收需要输出的显示图像。In 110, the display image may be a display image that the terminal needs to output. The terminal receives the display image that needs to be output frame by frame.

在120中，遮挡图案可以用于遮挡显示图像的部分信息。终端对每帧显示图像确定一个遮挡图案。In 120, the occlusion pattern can be used to occlude partial information of the displayed image. The terminal determines an occlusion pattern for each frame display image.

在本发明实施例中，每帧的遮挡图案可以遮挡对应帧显示图像的部分像素。连续帧的遮挡图案可以是不同的，可以按照一定的顺序变化。根据终端一秒钟输出图像的帧数，确定显示图像的每个像素在连续帧输出图像中至少有一次未被遮挡图案遮挡。为了满足用户需求，每帧中未被遮挡图案遮挡的显示图像满足视觉停留原理，以满足用户可以看到完整的显示图像。In the embodiment of the present invention, the occlusion pattern of each frame may block a part of pixels of the corresponding frame display image. The occlusion patterns of successive frames may be different and may vary in a certain order. According to the number of frames of the output image of the terminal for one second, it is determined that each pixel of the display image is occluded by the occlusion pattern at least once in the continuous frame output image. In order to meet the user's needs, the display image that is not blocked by the occlusion pattern in each frame satisfies the principle of visual pause, so that the user can see the complete display image.

其中，在本发明实施例中，N为终端每秒输出输出图像的帧数，。In the embodiment of the present invention, N is the number of frames of the output image output by the terminal per second.

在130中，终端逐帧输出图像，输出图像是显示图像和显示图像对应的遮挡图案的叠加。In 130, the terminal outputs an image frame by frame, and the output image is a superposition of the occlusion pattern corresponding to the display image and the display image.

因此，本发明实施例的技术方案公开了对每帧的显示图像设置遮挡图案，与终端输出帧率不匹配的拍摄设备无法通过拍摄获取终端的显示内容。本发明实施例的技术方案可以保护个人隐私，可以防止终端显示图像被偷拍，可以保证用户使用终端的安全性。Therefore, the technical solution of the embodiment of the present invention discloses that an occlusion pattern is set for a display image of each frame, and a photographing device that does not match the output frame rate of the terminal cannot acquire the display content of the terminal by photographing. Ben The technical solution of the embodiment of the invention can protect the privacy of the individual, can prevent the terminal from displaying the image to be photographed, and can ensure the security of the user using the terminal.

在本发明实施例中，遮挡图案包括规则形状的图案或不规则形状的图案。In an embodiment of the invention, the occlusion pattern comprises a pattern of a regular shape or a pattern of an irregular shape.

可选地，显示图像的每个像素在N帧连续输出的输出图像中至少一次未被遮挡图案遮挡。Optionally, each pixel of the display image is occluded by the occlusion pattern at least once in the output image continuously outputted by the N frames.

可选的，不同帧的显示图像对应的遮挡图案遮挡显示图像的不同部分的内容。Optionally, the occlusion pattern corresponding to the display image of different frames blocks the content of different parts of the displayed image.

可选地，作为本发明另一实施例，确定显示图像的遮挡图案包括：Optionally, as another embodiment of the present invention, determining the occlusion pattern of the display image includes:

沿第一方向移动第n帧遮挡图案，得到第n+1帧遮挡图案。其中，第n+1帧遮挡图案所遮挡的显示图像的部分像素可以为第n帧遮挡图案未遮挡的显示图像的部分像素，n取从1到N-1的正整数。The n-th frame occlusion pattern is moved in the first direction to obtain an n+1th frame occlusion pattern. The partial pixel of the display image blocked by the n+1th occlusion pattern may be a partial pixel of the display image that is not blocked by the nth frame occlusion pattern, and n takes a positive integer from 1 to N-1.

在本发明实施例中，n为连续接收帧信号中的前一帧信号，n+1为连续接收帧信号中第n帧信号之后的帧信号。第一方向为终端预设的任一方向。当终端为第n帧显示图像确定遮挡图案之后，终端将第n帧显示图像的遮挡图案沿预设的第一方向移动。将移动后的遮挡图案作为第n+1帧显示图像的遮挡图案。第n+1帧遮挡图案未遮挡的显示图像的像素可以为第n帧遮档图案遮挡的显示图像的全部或者部分像素。In the embodiment of the present invention, n is a previous frame signal in the continuous received frame signal, and n+1 is a frame signal subsequent to the nth frame signal in the continuous received frame signal. The first direction is any direction preset by the terminal. After the terminal determines the occlusion pattern for the nth frame display image, the terminal moves the occlusion pattern of the nth frame display image in a preset first direction. The occlusion pattern after the movement is used as an occlusion pattern of the image displayed in the n+1th frame. The pixel of the display image that is not blocked by the n+1th frame occlusion pattern may be all or part of the pixels of the display image occluded by the nth frame occlusion pattern.

下面以终端每秒输出60帧图像，以遮挡图案为横栅条为例，当横栅条和遮挡图案中的透明条的宽度相同时，对本发明的技术方案进行描述。In the following, the terminal outputs 60 frames of images per second, and the occlusion pattern is a horizontal grid. For example, when the widths of the transparent strips in the horizontal grid and the occlusion pattern are the same, the technical solution of the present invention will be described.

如图2和图3所示，图2为显示图像，图3A为第n帧输出图像，图3B为第n+1帧输出图像。图3A和图3B中未被遮挡图案遮挡的像素为透明条310部分。当终端输出的第20帧输出图像为图3A所示的图像时，遮挡图案遮挡部分显示图像的信息。终端按照一定的方向移动遮挡第20帧显示图像的遮挡图案作为第21帧显示图像的遮挡图案。As shown in FIG. 2 and FIG. 3, FIG. 2 is a display image, FIG. 3A is an n-th frame output image, and FIG. 3B is an n+1th frame output image. The pixels that are not obscured by the occlusion pattern in FIGS. 3A and 3B are portions of the transparent strip 310. When the 20th frame output image output by the terminal is the image shown in FIG. 3A, the occlusion pattern occlusion portion displays the information of the image. The terminal moves the occlusion pattern that blocks the display image of the 20th frame in a certain direction as the occlusion pattern of the 21st frame display image.

应理解，在本发明实施例中，终端以每秒输出60帧图像，遮挡图案为横条为例，只是为了说明本发明的技术方案，但本发明的技术方案并不受限于此。It should be understood that, in the embodiment of the present invention, the terminal outputs 60 frames of images per second, and blocks the pattern. The horizontal bar is taken as an example for the purpose of explaining the technical solution of the present invention, but the technical solution of the present invention is not limited thereto.

还应理解，在本发明实施例中，不同帧输出图像中被遮挡图案遮挡的图像可以部分重叠。显示图像的每个像素在连续N帧连续输出的输出图像中至少一次未被遮挡图案遮挡。It should also be understood that in embodiments of the present invention, images occluded by occlusion patterns in different frame output images may partially overlap. Each pixel of the display image is occluded by the occlusion pattern at least once in the output image continuously output for consecutive N frames.

在本发明实施例中，遮挡图案为规则形状的栅条型图案，该栅条型图案可以为横栅条图案、竖栅条图案或者斜栅条图案等其他栅条形状的图案。In the embodiment of the present invention, the occlusion pattern is a regular-shaped grid-type pattern, and the grid-type pattern may be a pattern of other grid shapes such as a horizontal grid pattern, a vertical grid pattern, or a diagonal grid pattern.

需要说明的是，在本发明实施例中，连续帧中的遮挡图案按照一定的方向移动。遮挡图案可以按照一定的顺序移动。例如，可以按照一定的速度移动。It should be noted that, in the embodiment of the present invention, the occlusion pattern in consecutive frames moves in a certain direction. The occlusion patterns can be moved in a certain order. For example, you can move at a certain speed.

还应理解，在本发明实施例中，当遮挡图案满足条件：每帧遮挡图案遮挡对应帧显示图像的一部分，且每帧显示图像的每个像素在N帧连续输出的输出图像中至少一次未被遮挡图案遮挡，N帧连续输出的输出图像中，每帧遮挡图案未遮挡的显示图像满足视觉停留原理，N为每秒中输出的显示图像的帧数。遮挡图案还可以无规则的运动。在本发明实施例中对此不作任何限制。It should also be understood that, in the embodiment of the present invention, when the occlusion pattern satisfies the condition: each frame occlusion pattern occludes a portion of the corresponding frame display image, and each pixel of each frame display image is not at least once in the output image continuously outputted by N frames. The occlusion pattern is occluded, and in the output image continuously outputted by N frames, the display image whose occlusion pattern is not occluded per frame satisfies the principle of visual stagnation, and N is the number of frames of the display image outputted per second. The occlusion pattern can also move irregularly. There is no limitation on this in the embodiment of the present invention.

可选地，作为本发明的另一实施例，该方法100还包括：当遮挡图案为栅条型图案时，确定栅条型图案的宽度和栅条型图案的间距。Optionally, as another embodiment of the present invention, the method 100 further includes determining a width of the grid-type pattern and a pitch of the grid-type pattern when the occlusion pattern is a grid-type pattern.

在本发明实施例中，当遮挡图案为栅条型图案时，终端可以确定栅条型图案的宽度和间距。例如，终端根据输出的显示图像的大小，确定栅条型图案的宽度和间距。在该实施例中，遮挡图案可以为等间距、不等间距、等宽度和/或不等宽度的图案。In the embodiment of the present invention, when the occlusion pattern is a grid-type pattern, the terminal may determine the width and the pitch of the grid-type pattern. For example, the terminal determines the width and spacing of the grid-type pattern according to the size of the output image to be output. In this embodiment, the occlusion pattern may be a pattern of equal pitch, unequal pitch, equal width, and/or unequal width.

可选地，作为本发明的另一实施例，该方法100还可以包括：确定每帧遮挡图案的颜色。Optionally, as another embodiment of the present invention, the method 100 may further include: determining a color of each frame occlusion pattern.

在本发明实施例中，终端可以为每帧遮挡图案设置颜色。每帧遮挡图案的颜色可以为固定颜色，也可以为不相同的颜色。 In the embodiment of the present invention, the terminal may set a color for each frame occlusion pattern. The color of each frame occlusion pattern can be a fixed color or a different color.

在本发明实施例中，终端还可以为每帧的遮挡图案设置不同的视觉效果。例如，终端为遮挡图案设置不同的透明度，或者终端将遮挡图案设置为特殊效果，再例如，毛玻璃效果。In the embodiment of the present invention, the terminal may also set different visual effects for the occlusion pattern of each frame. For example, the terminal sets different transparency for the occlusion pattern, or the terminal sets the occlusion pattern to a special effect, for example, a frosted glass effect.

优选地，在本发明实施例中，当终端开启一次遮挡图案时，该次输出的每帧输出图像的遮挡图案为同一种颜色、同一种透明度和/或同一种特殊效果，以降低颜色、透明度和/或特殊效果变化对眼睛的刺激，用以保护眼睛。当终端多次开启遮挡图案时，每次的遮挡图案颜色、透明度和/或特殊效果可以不一致，以用于用户使用过程中视觉的多样性，提高用户体验。Preferably, in the embodiment of the present invention, when the terminal opens the occlusion pattern once, the occlusion pattern of each output image of the output is the same color, the same transparency and/or the same special effect to reduce color and transparency. And/or special effects change the eye's stimuli to protect the eyes. When the terminal opens the occlusion pattern multiple times, the occlusion pattern color, transparency, and/or special effects may be inconsistent for the user to use the visual diversity during use to improve the user experience.

在本发明实施例中，终端还可以调整遮挡图案的亮度和或灰度，例如，终端可以将调整终端显示器屏幕的亮度与调整遮挡图案的亮度和或灰度相结合调整，同时调整终端显示器屏幕的亮度和遮挡图案的亮度和或灰度，以提高用户的体验。In the embodiment of the present invention, the terminal may further adjust the brightness and gray level of the occlusion pattern. For example, the terminal may adjust the brightness of the adjustment terminal display screen in combination with the brightness and gray level of the adjustment occlusion pattern, and adjust the terminal display screen. The brightness and opacity of the occlusion pattern and or grayscale to enhance the user experience.

可选地，作为本发明另一实施例，每帧遮挡图案分布于部分显示图像上或者每帧遮挡图案分布于整个显示图像上。Optionally, as another embodiment of the present invention, each frame of the occlusion pattern is distributed on the partial display image or each frame of the occlusion pattern is distributed on the entire display image.

具体的，每帧的遮挡图案可以分布于整个显示图像上，也可以分布在整个显示图像的部分显示图像上，也就是说，终端遮挡图案可以遮挡显示器所有区域的显示图像，也可以遮挡显示器部分区域的显示图像。Specifically, the occlusion pattern of each frame may be distributed over the entire display image, or may be distributed over part of the display image of the entire display image, that is, the terminal occlusion pattern may block the display image of all areas of the display, and may also block the display portion.

图5是本发明实施例终端的示意性结构图。如图5所示的终端500包括：接收模块510、确定模块520和输出模块530。FIG. 5 is a schematic structural diagram of a terminal according to an embodiment of the present invention. The terminal 500 shown in FIG. 5 includes a receiving module 510, a determining module 520, and an output module 530.

接收模块510，用于逐帧接收显示图像；The receiving module 510 is configured to receive the display image frame by frame;

确定模块，用于确定每帧显示图像的遮挡图案，遮挡图案遮挡显示图像的一部分； a determining module, configured to determine an occlusion pattern of the displayed image of each frame, the occlusion pattern occluding a portion of the displayed image;

输出模块530，用于逐帧输出图像，输出图像为显示图像与所述显示图像对应的遮挡图案的叠加。The output module 530 is configured to output an image frame by frame, and the output image is a superposition of the occlusion pattern corresponding to the display image and the display image.

其中，每帧显示图像的每个像素在N帧连续输出的输出图像中至少出现一次未被遮挡图案遮挡，N帧连续输出的输出图像中，每帧遮挡图案未遮挡部分的显示图像满足视觉停留原理，N取正整数。Wherein, each pixel of each frame display image is occluded at least once by the occlusion pattern in the output image continuously outputted by the N frames, and the output image of the unblocked portion of each frame occlusion pattern satisfies the visual pause in the output image continuously outputted by the N frames. Principle, N takes a positive integer.

具体的，在本发明实施例中，终端按照预设帧率输出图像。每个终端使用的帧率满足视觉停留原理。确定模块520对接收模块510接收的每帧显示图像进行处理，在每帧的显示图像上叠加遮挡图案，合成最终的输出图像。每帧的遮挡图案可以只遮挡该帧显示图像的部分像素。由于输出图像包括显示图像和遮挡图案，在每一帧输出图像中，由于显示图像的部分像素被遮挡图案遮挡，所以每帧输出图像可能无法呈现完整的显示图像，每帧显示图像的每个像素在N帧连续输出的输出图像中至少出现一次未被遮挡图案遮挡，结合视觉停留原理，用户可以看到完整的显示图像。其中，连续输出帧中的遮挡图案可以按照一定的顺序变化。Specifically, in the embodiment of the present invention, the terminal outputs an image according to a preset frame rate. The frame rate used by each terminal satisfies the principle of visual pause. The determining module 520 processes each frame of the display image received by the receiving module 510, and superimposes the occlusion pattern on the display image of each frame to synthesize the final output image. The occlusion pattern of each frame may only obscure a portion of the pixels of the frame display image. Since the output image includes the display image and the occlusion pattern, in each frame output image, since some pixels of the display image are blocked by the occlusion pattern, the output image of each frame may not be able to present a complete display image, and each pixel of the image is displayed per frame. The unoccluded pattern is occluded at least once in the output image continuously outputted by N frames. In combination with the principle of visual pause, the user can see the complete display image. The occlusion patterns in the continuous output frame may be changed in a certain order.

According to the number of frames of the output image of the terminal for one second, it is determined that each pixel of the display image is occluded at least once by the occlusion pattern in the specified continuous frame output image, and the display is blocked by the occlusion pattern in each frame to meet the user's demand. Part of the display image satisfies the principle of visual pause so that the user can see the complete display image. That is to say, when the preset frame rate satisfies the time of the user's visual pause, when the image is output in consecutive N frames, the user can keep the image of the previous frame in the line of sight of the user when the next frame image is seen, so that the user can See the full display image.
