技术领域technical field
本发明涉及显示技术，尤其涉及一种显示处理方法及装置、终端。The present invention relates to display technology, in particular to a display processing method and device, and a terminal.
背景技术Background technique
采用柱镜光栅技术的裸眼3D装置，在进行竖屏观看的时候，柱镜光栅中的各个柱状透镜的排列方向(以下简称为柱镜光栅的方向)与人眼方向(也即两眼确定的方向)平行；在进行横屏观看的时候，柱镜光栅的方向与人眼方向垂直。The naked-eye 3D device adopting the lenticular technology, when viewing the vertical screen, the arrangement direction of each lenticular lens in the lenticular lens (hereinafter referred to as the direction of the lenticular lens) is closely related to the direction of the human eye (that is, the direction determined by two eyes). direction) parallel; when viewed in landscape mode, the direction of the lenticular lens grating is perpendicular to the direction of the human eye.
其中，在进行横屏观看的时候，将左右格式的视频源的每一帧图像数据进行交织排序后，透过柱镜光栅对光的折射作用，将不同的显示内容折射到空间中不同的地方，光线到达人眼时显示的内容被分开，人眼接收到两幅含有视差的图像，这样便产生了裸眼3D的立体效果。Among them, when viewing in horizontal screen, after interleaving and sorting each frame of image data of left and right format video sources, through the refraction effect of lenticular grating on light, different display contents are refracted to different places in space , when the light reaches the human eye, the displayed content is separated, and the human eye receives two images containing parallax, thus producing a stereoscopic effect of naked-eye 3D.
在进行竖屏观看的时候，柱镜光栅的方向与人眼方向平行，同样因为柱镜光栅对光的折射作用，将不同的显示内容折射到空间中不同的地方，人眼只能看到一半的画面，垂直分辨率损失了一半。对于单像素的横线会存在在某些角度看不到的问题，对于双像素或多像素的横向会存在一半的横线像素看不到的问题，导致人眼在观看的时候非常不适应，字体横线粗细发生变化，字体边缘粗糙等问题。When viewing on a vertical screen, the direction of the lenticular lens is parallel to the direction of the human eye. Also because of the refraction of the lenticular lens to light, different display content is refracted to different places in the space, and the human eye can only see half of it. , the vertical resolution is lost by half. For single-pixel horizontal lines, there will be problems that cannot be seen at certain angles, and for double-pixel or multi-pixel horizontal lines, there will be a problem that half of the horizontal line pixels cannot be seen, which makes human eyes very uncomfortable when viewing. The thickness of the horizontal line of the font changes, and the edges of the font are rough.

具体实施方式Detailed ways
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.
现实世界是一个三维空间，除去时间这一维度，现实世界是由长度、宽度和高度三个维度组成，而现有的显示设备大多数都只能显示二维信息，并不能带给人真实的三维感觉。为了使显示的物体和场景具有深度感(也就是3D)，技术人员纷纷对3D显示技术展开研究。The real world is a three-dimensional space. Excluding the dimension of time, the real world is composed of three dimensions: length, width and height. However, most of the existing display devices can only display two-dimensional information and cannot bring people real Three-dimensional feeling. In order to make displayed objects and scenes have a sense of depth (that is, 3D), technical personnel have conducted research on 3D display technology.
对于三维世界而言，人眼观看物体时看到的图像具有位差，两幅图像之间的偏差称之为视差(disparity/parallax)。正是这种视差，使人们能区别物体的远近，并获得立体感。根据视差值的不同，视差又可分为正视差(positive parallax)，负视差(negativeparallax)和零视差(zero parallax)。当用户在观看时，正视差使人产生物体深入屏幕的感觉；负视差使人产生物体悬浮于屏幕外的感觉；零视差是正视差和负视差的分界，物体刚好被投射到屏幕上，即零平面。For the three-dimensional world, the images seen by human eyes when viewing objects have disparity, and the deviation between two images is called disparity (parallax). It is this kind of parallax that enables people to distinguish the distance of objects and obtain a sense of three-dimensionality. According to different parallax values, parallax can be divided into positive parallax (positive parallax), negative parallax (negative parallax) and zero parallax (zero parallax). When the user is watching, positive parallax makes people feel that the object goes deep into the screen; negative parallax makes people feel that the object is floating outside the screen; zero parallax is the boundary between positive and negative parallax, and the object is just projected on the screen, that is, zero flat.
人的大脑可以将映入双眼的两幅具有视差的图像，经视神经中枢的融合反射，以及视觉心理反应便可产生三维立体感觉。利用这个原理，可以将两幅具有视差的左右图像通过显示器显示，将其分别送给左右眼，从而获得3D感。The human brain can reflect two images with parallax reflected in the eyes, and through the fusion reflection of the optic nerve center and the visual psychological reaction, a three-dimensional stereoscopic feeling can be produced. Utilizing this principle, two left and right images with parallax can be displayed on the display and sent to the left and right eyes respectively, thereby obtaining a 3D sense.
裸眼3D显示的原理一般是通过光栅(如狭缝光栅、柱镜光栅)将显示器，也即屏幕显示的图像进行分光，从而使人眼接收到不同的图像，这样便实现了3D显示。The principle of naked-eye 3D display is generally to split the display, that is, the image displayed on the screen, through a grating (such as a slit grating, a lenticular grating), so that the human eye receives different images, thus realizing 3D display.
狭缝光栅显示器通过在显示面板前方放置一个参数合适的狭缝光栅，对显示的内容进行遮挡，在经过一定距离后，到达人眼的光线便可被分开，双眼接收到两幅含有视差的图像，如图1所示。The slit grating display blocks the displayed content by placing a slit grating with suitable parameters in front of the display panel. After a certain distance, the light rays reaching the human eyes can be separated, and the two eyes receive two images with parallax ,As shown in Figure 1.
柱镜光栅显示器与狭缝光栅显示器同理，只是实现的方式由狭缝换成了透镜，透镜通过对光的折射作用，将不同的显示内容折射到空间中不同的地方，到达人眼时显示的内容被分开，人眼接收到两幅含有视差的图像，这样便产生了立体效果，如图2所示。The lenticular grating display is the same as the slit grating display, except that the realization method is changed from a slit to a lens. The lens refracts different display contents to different places in the space through the refraction of light, and displays when it reaches the human eye. The content of is separated, and the human eye receives two images with parallax, thus producing a stereoscopic effect, as shown in Figure 2.
基于以上所述，裸眼立体显示基于立体视觉原理，通过改进立体显示器，以特定光学遮挡和光路传播控制的方式，实现将含有视差的图像分别传送到人的左右眼睛，进而观看到立体影像。Based on the above, glasses-free stereoscopic display is based on the principle of stereoscopic vision. By improving the stereoscopic display, the images containing parallax can be transmitted to the left and right eyes of the person respectively by means of specific optical occlusion and optical path propagation control, and then the stereoscopic image can be viewed.
裸眼3D显示处理装置，需要人眼的方向与柱镜光栅的方向垂直，即横屏观看的时候才能够看到裸眼3D的效果，当人眼的方向与柱镜光栅的方向平行，即竖屏观看的时候只能看到2D的效果，且竖着看的时候垂直分辨率损失一半。Glasses-free 3D display processing device requires the direction of the human eye to be perpendicular to the direction of the lenticular grating, that is, the naked-eye 3D effect can only be seen when viewing the horizontal screen. When the direction of the human eye is parallel to the direction of the lenticular grating, that is, the vertical screen Only 2D effects can be seen when viewing, and the vertical resolution is lost by half when viewed vertically.
这里，屏幕的分辨率通过水平分辨率和垂直分辨率来描述，其中，水平是指与人眼平行的方向，垂直是指与人眼垂直的方向，比如，1920×1080分辨率的屏幕，竖着看的时候，垂直方向的分辨率(也即沿列方向的分辨率)是1920，水平方向(也即沿行方向的分辨率)的分辨率是1080，如图3所示的竖屏方向，如图4所示的横屏方向。其中，屏幕的表面具有柱镜光栅，柱镜光栅由多个柱状透镜组成，参照图5，柱状透镜的方向(也即柱镜光栅的方向)为屏幕的行方向。在一示例中，每个柱状透镜下面有两行的像素。Here, the resolution of the screen is described by horizontal resolution and vertical resolution, where horizontal refers to the direction parallel to human eyes, and vertical refers to the direction perpendicular to human eyes. For example, for a screen with a resolution of 1920×1080, vertical When looking at it, the resolution in the vertical direction (that is, the resolution along the column direction) is 1920, and the resolution in the horizontal direction (that is, the resolution along the row direction) is 1080, as shown in Figure 3 in the vertical screen direction , in landscape orientation as shown in Figure 4. Wherein, the surface of the screen has a lenticular lens grating, and the lenticular lens grating is composed of a plurality of lenticular lenses. Referring to FIG. 5 , the direction of the lenticular lens (that is, the direction of the lenticular lens grating) is the row direction of the screen. In one example, there are two rows of pixels under each lenticular lens.
本发明实施例的技术方案，提供了一种具体3D显示屏的装置在2D显示模式下的图像处理算法，当柱镜光栅的方向与人眼方向垂直时，可以看到裸眼3D效果；当柱镜光栅的方向与人眼方向平行时，可以看到普通的2D效果，并且解决了垂直分辨率损失一半的问题。The technical solution of the embodiment of the present invention provides an image processing algorithm for a specific 3D display device in 2D display mode. When the direction of the lenticular grating is perpendicular to the direction of the human eye, the naked-eye 3D effect can be seen; When the direction of the mirror grating is parallel to the direction of the human eye, ordinary 2D effects can be seen, and the problem of losing half of the vertical resolution is solved.
图6为本发明实施例的显示处理方法的流程示意图一，如图6所示，所述显示处理方法包括：FIG. 6 is a first schematic flow chart of a display processing method according to an embodiment of the present invention. As shown in FIG. 6 , the display processing method includes:
步骤601：将待显示图像的帧图像沿屏幕上列方向的分辨率压缩至1/N倍，N≥2，其中，所述屏幕具有光栅结构，所述列方向为与所述光栅结构垂直的方向。Step 601: Compress the resolution of the frame image of the image to be displayed along the column direction on the screen to 1/N times, N≥2, wherein the screen has a grating structure, and the column direction is perpendicular to the grating structure direction.
所述将待显示图像的帧图像沿屏幕上列方向的分辨率压缩至1/N倍之前，所述方法还包括：Before compressing the resolution of the frame image of the image to be displayed along the column direction on the screen to 1/N times, the method further includes:
确定所述屏幕当前的显示模式是第一显示模式；其中所述第一显示模式为二维显示模式。It is determined that the current display mode of the screen is a first display mode; wherein the first display mode is a two-dimensional display mode.
本发明实施例中，所述确定所述屏幕当前的显示模式是第一显示模式，包括：In the embodiment of the present invention, the determining that the current display mode of the screen is the first display mode includes:
检测终端的位姿参数；根据所述位姿参数，判断所述屏幕的显示模式是否为所述第一显示模式。Detecting pose parameters of the terminal; judging whether the display mode of the screen is the first display mode according to the pose parameters.
在一示例中，位姿参数为角度Angle，参照图11，通过加速度传感器检测Angle的计算方法如下：In one example, the pose parameter is the angle Angle. Referring to FIG. 11 , the calculation method of detecting Angle through the acceleration sensor is as follows:
Angle＝-arcsin(z/Magnitude)×RADIANS_TO_DEGREES；Angle=-arcsin(z/Magnitude)×RADIANS_TO_DEGREES;
其中，RADIANS_TO_DEGREES＝180/π；Among them, RADIANS_TO_DEGREES = 180/π;
x，y，z为加速度传感器三轴方向的加速度值。 x, y, z are the acceleration values in the three-axis direction of the acceleration sensor.
其中，Angle的值范围为[-90°,90°]，-90°表示横屏朝上方向，0°表示垂直方向，90°表示横屏朝下方向。Among them, the value range of Angle is [-90°,90°], -90° indicates the upward direction of the horizontal screen, 0° indicates the vertical direction, and 90° indicates the downward direction of the horizontal screen.
本发明实施例中，所述确定所述屏幕当前的显示模式是第一显示模式，包括：In the embodiment of the present invention, the determining that the current display mode of the screen is the first display mode includes:
获得设置操作；基于所述设置操作，判断所述屏幕的显示模式是否为所述第一显示模式。A setting operation is obtained; based on the setting operation, it is judged whether the display mode of the screen is the first display mode.
本发明实施例中，第一显示模式是指二维显示模式，在具体实现时，二维显示模式也即横屏显示模式；相对地，屏幕还具有第二显示模式，其中，第二显示模式是指三维显示模式，具体实现时，三维显示模也即竖屏显示模式。In the embodiment of the present invention, the first display mode refers to the two-dimensional display mode. In actual implementation, the two-dimensional display mode is also the horizontal screen display mode; relatively, the screen also has a second display mode, wherein the second display mode Refers to the three-dimensional display mode. In actual implementation, the three-dimensional display mode is also the vertical screen display mode.
本发明实施例中，所述显示所述待显示图像包括将所述光栅结构的每一光栅对应所述M行相同像素。In the embodiment of the present invention, the displaying the image to be displayed includes associating each grating of the grating structure with the M rows of identical pixels.
本发明实施例中，所述光栅为柱镜光栅。In the embodiment of the present invention, the grating is a lenticular grating.
在一具体实施方式中，M为大于或等于2的偶数。M小于或等于N。In a specific embodiment, M is an even number greater than or equal to 2. M is less than or equal to N.
这里，以M为2为例，光栅结构的每一光栅就对应2行相同的像素，由于像素相同，因而可以弥补垂直分辨率损失一半的问题。当然，M还可以为4、6等其他偶数，这可以根据光栅结构的每一光栅对应的行数而确定。Here, taking M as 2 as an example, each grating of the grating structure corresponds to 2 rows of identical pixels. Since the pixels are the same, the problem of losing half of the vertical resolution can be compensated. Of course, M can also be other even numbers such as 4 and 6, which can be determined according to the number of rows corresponding to each grating of the grating structure.
M＝N时，帧图像处理之前和处理之后的像素点相同，因而具有相同的显示区域。当M小于N时，帧图像处理之后的像素点少于处理之前的像素点，这种情况下，帧图像处理之后的显示区域相对于处理之前缩小了，可以方便用户单手操作。When M=N, the frame image has the same pixel points before and after processing, and thus has the same display area. When M is smaller than N, the number of pixels after frame image processing is less than that before processing. In this case, the display area after frame image processing is smaller than that before processing, which is convenient for users to operate with one hand.
本发明实施例中，所述将待显示图像的帧图像沿屏幕上列方向的分辨率压缩至1/N倍时，采用以下任意一种压缩算法进行压缩：In the embodiment of the present invention, when compressing the resolution of the frame image of the image to be displayed along the upper column direction of the screen to 1/N times, any of the following compression algorithms is used for compression:
二次线性插值、三次卷积算法、两次立方算法。Quadratic Linear Interpolation, Cubic Convolution Algorithm, Bicubic Algorithm.
本发明实施例中，基于所述目标图像的内容，确定所采用的压缩算法。在一具体示例中，可以根据不同的显示内容(图片、文字)采用不同的压缩算法，以达到最佳的用户体验效果。比如，在2D显示模式下，简单文字浏览时，采用二次线性插值算法，以达到性能最优的前提下满足文字效果阅读；在2D显示模式下，图库浏览时，采用两次立方算法，增加压缩算法处理，以达到效果优先。In the embodiment of the present invention, the compression algorithm adopted is determined based on the content of the target image. In a specific example, different compression algorithms may be used according to different display contents (pictures, texts) to achieve the best user experience effect. For example, in the 2D display mode, when browsing simple text, the quadratic linear interpolation algorithm is used to meet the text effect reading under the premise of optimal performance; The compression algorithm is processed to achieve the effect first.
在一具体示例中，将一帧画面通过采样压缩的方法，将垂直分辨率压缩一半，水平分辨率保持不变。例如，针对1920×1080分辨率的图像，竖屏情况下，1920像素点代表垂直分辨率，1080像素点代表水平分辨率；将每一帧1920×1080的图像通过一定的算法采样压缩为960×1080的图像。In a specific example, a frame of picture is compressed by sampling, and the vertical resolution is compressed by half, while the horizontal resolution remains unchanged. For example, for an image with a resolution of 1920×1080, in the case of a vertical screen, 1920 pixels represent the vertical resolution, and 1080 pixels represent the horizontal resolution; each frame of 1920×1080 image is sampled and compressed to 960× by a certain algorithm 1080p images.

参照图10，将压缩处理得到的每一帧960×1080的图像，再次经过倍行(doubleline)的编码方式得到1920×1080的图像，输入到显示屏进行显示。Referring to FIG. 10 , the 960×1080 image of each frame obtained through the compression process is again encoded by doubleline to obtain a 1920×1080 image, which is input to the display screen for display.
在一具体示例中，将压缩得到的一帧960×1080分辨率的图像按行分为960张1×1080像素的图像；其次，960张单行像素的图像，采用倍行(double line)的方式重新编码组合成一副1920×1080分辨率的图像进行显示。In a specific example, a compressed image with a resolution of 960×1080 is divided into 960 images of 1×1080 pixels by row; secondly, the 960 images of a single row of pixels are double-lined Re-encode and combine to form a 1920×1080 resolution image for display.
