Description

图像处理效果对比显示系统和显示方法 技术领域  Image processing effect contrast display system and display method
本发明涉及一种图像处理效果对比显示系统和显示方法， 尤其是一种根 据使能信号将经过不同处理后的图像信号， 显示在不同的对比显示窗， 并且 可以对 0SD区域进行保护， 不显示经过处理后的图像， 只显示原始图像信号 实现图像处理效果对比的显示系统和显示方法。 背景技术  The invention relates to an image processing effect comparison display system and a display method, in particular to an image signal which has undergone different processing according to an enable signal, which is displayed on different contrast display windows, and can protect the 0SD area without displaying After the processed image, only the original image signal is displayed to realize the display system and the display method for comparing the image processing effects. Background technique
电子和信号处理技术发展的今天， 图像及视频的处理日趋成熟。 例如 运动自适应隔行转逐行处理, 基于运动分析的去抖动智能插值, 动态对比 度增强， 多维图像细节增强以及智能化的颜色增强校正处理等等， 这些技 术使得人们看到的图像质量越来越高， 也使得电子产品越来越考虑人们的 健康。 与此同时， 由于图像和视频的现实效果只能是人的主观感觉， 因此 就无法用一个统一的标准来对图像质量进行量化； 而视频处理技术的每一 次进步如果能够得到市场和用户的认可将有利于下一步的发展， 为技术的 持续发展提供原动力。 而对于技术进步带来的益处， 在实际应用中需要一 些帮助人们辨别技术处理后的效果的方法， 用于更有效地展示视频经过不 同处理后带来的效果。 这既有利于消费者做出正确的判断， 也利于产品的 市场推广。  With the development of electronic and signal processing technologies, the processing of images and video is becoming more mature. For example, motion adaptive interlaced to progressive processing, motion-based de-jitter intelligent interpolation, dynamic contrast enhancement, multi-dimensional image detail enhancement, and intelligent color enhancement correction processing, etc., which make people see more and more image quality. High, it also makes electronic products more and more consider people's health. At the same time, since the reality of images and video can only be a subjective feeling of human beings, it is impossible to quantify image quality with a unified standard; and every progress of video processing technology can be recognized by the market and users. It will be conducive to the next step of development and provide the driving force for the sustainable development of technology. For the benefit of technological advancement, in practice, some methods are needed to help people identify the effects of technical processing, and to more effectively display the effects of video after different processing. This will not only help consumers make correct judgments, but also facilitate the marketing of products.
现有的电子产品的图像处理效果对比显示装置和其显示方法主要是 静态的左右分屏演示， 因此形状单一， 模式固定。 因此无法实现多窗口动 态变化地对比显示经过不同图像处理后的效果。  The image processing effect comparison display device and the display method of the existing electronic products are mainly static left and right split screen presentations, so the shape is single and the mode is fixed. Therefore, it is impossible to compare the effects of multi-window dynamic display after different image processing.
并且， 由于图像视频处理系统中的一些应用将部分增强处理放在包括 屏幕控制系统 （On-Screen Di spl ay , OSD)主功能模块， 因此， 对 OSD区 域也必须进行图像处理， 而在大多数情况下是不希望对 0SD区域进行处理 的， 但是现有的图像处理系统和处理方法都无法对 OSD区域进行保护， 不 予处理。 发明内容 Moreover, since some applications in the image video processing system place partial enhancement processing on the main function module including the On-Screen Di spl ay (OSD), image processing must also be performed on the OSD area, and in most In case, you do not want to process the 0SD area.

如图 4所示， 为本发明图像处理效果对比显示方法是实例 1的流程图， 详细步 如下：  As shown in FIG. 4, the image processing effect comparison display method of the present invention is a flowchart of Example 1, and the detailed steps are as follows:
步骤 101 , 窗口特征定义及计算装置计算图像效果对比显示窗的形状、 大小和运动方向信号， 以及对比显示窗的宽度、 形状和颜色信号， 均输入使 能信号及填充信号发生器；  Step 101: The window feature definition and the computing device calculate an image effect contrast display window shape, a size, and a motion direction signal, and compare the width, shape, and color signals of the display window, and input an enable signal and a fill signal generator;
并且还可以包括图像效果对比显示窗内的子窗口的形状、 大小和运动方 向信号， 以及子窗口的边框宽度、 形状和颜色信号， 也均输入使能信号及填 充信号发生器；  And the image effect can also include the shape, size and motion direction signal of the sub-window in the display window, and the border width, shape and color signal of the sub-window, and the input enable signal and the filling signal generator;
对比显示演示窗口和窗口内的子窗口， 其形状可以是矩形、 圓形、 扇 形以及各种不规则形状（如 Logo的图标形状） ； 边框的形状可以是平坦 方式、 凸凹方式， 也可以是其他更为复杂的立体形状等； 边框的宽度为可 调整， 如果宽度为零则无可视边框；  The comparison shows the presentation window and the sub-window in the window. The shape can be rectangular, circular, fan-shaped, and various irregular shapes (such as the logo shape of the logo); the shape of the border can be flat, convex or concave, or other More complex three-dimensional shapes, etc.; the width of the border is adjustable, if the width is zero, there is no visible border;
对比显示演示窗口和窗口内的子窗口分别计算运动速度和方向， 主窗 口下的子窗口随同主窗口的运动特征； 运动方向的定义才艮据显示设备的扫 描方式分解成水平方向 ( v、）和垂直方向 ( V、,）， Vx = Vv = 0时表示静态区域; 当演示区域运动到有效图像或者显示设备边沿时的碰撞模型包括如反射、 粘滞反射、 边形反射等； 并且包括主窗口的边框和自窗口间的边框； Comparing the display window and the sub-window in the window respectively calculate the motion speed and direction, and the sub-window under the main window follows the motion characteristics of the main window; the definition of the motion direction is decomposed into a horizontal direction according to the scanning mode of the display device (v,) And the vertical direction (V,,), V x = V v = 0 represents the static area; when the demonstration area moves to the effective image or the edge of the display device, the collision model includes, for example, reflection, viscous reflection, edge reflection, etc.; Includes the border of the main window and the border between the windows;
对比显示演示窗口和窗口内的子窗口定义的形状、 边沿以及运动模型 可以基于预设的计算方式用组合逻辑来实时计算， 也可以利用 memory来 描述这些特性， 前者主要用于规则的固定模式的特征定义， 如圓形、 平坦 边框以及直线匀速运动等，一旦定义行为不易改变；后者用于定义不规则， 难以用闭式描述的特征， 如不规则图像、 边框以及非线性的运动反射等, 这种方法具有较高的灵活性， 但是开销较大；  Contrast display The shape, edge and motion model defined by the sub-window in the demo window and window can be calculated in real time by combinatorial logic based on the preset calculation method. These characteristics can also be described by using memory. The former is mainly used for the fixed mode of the rule. Feature definitions, such as circular, flat borders, and straight-line motion, are not easy to change once defined; the latter are used to define irregularities, features that are difficult to describe in closed form, such as irregular images, borders, and nonlinear motion reflections. This method has higher flexibility, but the overhead is larger;
例如如图 5所示， 根据图像视频在显示设备上的显示模式， 确定区分 演示窗口为一个圆形， 大小根据需要定为外半径为 150- -300像素， 用 Memory确定可变宽度的圆形窗口边框，用寄存器定义边框部分的颜色分量 值， 根据设定的圓心的运动速度和方向定义每一场 /帧圆心对应的位置， 从而计算得到每个像素处于： 圆形窗口内（a) , 圆形窗口外（b) , 圓形窗口 编筐内（c) ; 定义圆心最大的运动边框坐标， 当圓心遇到这个边框时， 改 变运动方向 /速度， 对于圆形的内外半径也可以动态改变以改变相应的圆 形窗口大小； For example, as shown in FIG. 5, according to the display mode of the image video on the display device, it is determined that the presentation window is a circle, and the size is set to an outer radius of 150-300 pixels as needed. Memory determines the circular window border of variable width, and uses the register to define the color component value of the border portion, and defines the position corresponding to the center of each field/frame according to the movement speed and direction of the set center, thereby calculating that each pixel is: Inside the circular window (a), outside the circular window (b), inside the circular window frame (c); define the coordinates of the largest moving frame of the center of the circle, when the center of the circle encounters this border, change the direction/speed of motion, for the circle The inner and outer radii of the shape can also be dynamically changed to change the corresponding circular window size;
或者如图 6至 9所示， 根据图像视频在显示设备上的显示模式， 确定 区分演示窗口为一个矩形区域， 大小根据需要确定， 用计算的方式确定可 变宽度的矩形主窗口边框， 用寄存器定义边框部分的颜色分量值， 这里确 定主窗口为静止矩形区域， 然后判断主演示窗口下下是否有子窗口， 若有 确定子窗口间边沿为单双向 （参见图 6 ) 的左右 （参见图 7 )上下 （参见 图 8 )或者斜向 （参见图 9 ) 的 SWEEP方式， 运动可以是双向的也可以是 单向的； 当然， 也可以采用入图 10至 1 3中较为简单的方式， 将演示窗口 定义为屏幕的垂直或者水平方向的中间部分（或者对半部分） ， 从而将屏 幕分割成三 （两）部分， 窗口显示区域可以是固定的， 也可以是运动的， 边框可以是零像素宽度， 也可以是具有一定像素宽度的边沿， 窗口显示区 域内外的演示可以互换；  Or as shown in FIG. 6 to FIG. 9, according to the display mode of the image video on the display device, determining that the presentation window is a rectangular area, the size is determined according to requirements, and the variable width rectangular main window frame is determined by calculation, and the register is used. Define the color component value of the border part. Here, determine that the main window is a still rectangular area, and then determine whether there is a sub-window under the main presentation window. If there is a certain edge between the sub-windows, the left and right sides (see Figure 6) are left and right (see Figure 7). The SWEEP mode of up and down (see Figure 8) or diagonal (see Figure 9), the motion can be bidirectional or unidirectional; of course, it can also be demonstrated in a simpler way in Figures 10 to 13.
