利用计算机进行图像处理,就是将图像的形象和色彩通过光电变化转换为数字模式输入到计算机进行存储,计算机将这些数字模式编辑处理成不同密度的色彩等级通过彩色显示屏演示出来。我们以显示屏为媒介,将我们创作活动自始至终在显示屏上完成。通过人机对话,将自已的创作意图及修正意见传达给计算机,通过键盘向计算机发出指令,同时,我们利用光笔直接对显示屏中的图像进行加工修改。软件编制人员为计算机汇编了各种编辑功能,借助于这些功能,我们可任意对图像进行位移、放大及缩小、错切、角度旋转等,我们所使用的光笔不仅具有传输指令的作用,而且还能够模拟画笔、刷及喷笔等功能用以对画面进行涂绘和修改。此外,计算机拥有庞大的色彩储存系统,能容纳1千6百万种颜色,计算机的数字存储模式又能将色彩明度和纯度精确地分为256个等级。我们借助于丰富的色彩可以随心所欲的调整图像色彩,或增强渲染,或减弱淡化,或鲜明夺目,或富于梦幻情调。此外计算机还可对色彩内存数据自由搭配对图像变调处理,它不受我们的习惯色彩观念的限制,
The use of computers for image processing, is the image of the image and color through the photoelectric conversion into digital mode input to the computer for storage, the computer will edit these digital modes into different density levels of color through the color display demonstration. We use the display as a medium to complete our creative activity throughout the display. Through human-computer dialogue, will convey their own creative intent and amendments to the computer, through the keyboard to the computer instructions, at the same time, we use the light pen directly on the screen image processing modification. Software compilers for the computer compilation of a variety of editing features, with the help of these features, we can arbitrarily shift the image, zoom in and out, wrong cut, angle rotation, etc., we use the light pen not only has the role of transmission instructions, but also Able to simulate the brush, brush and pen features such as painting to the screen painted and modified. In addition, the computer has a large color storage system that can hold 16 million colors, and the computer’s digital storage model accurately divides color brightness and purity into 256 levels. With the help of rich colors, we can adjust the color of the images as much as we like, or enhance the rendering, weakened or descended, or the eye-catching or full of fantastic moods. In addition, the computer can also freely match the color memory data on the image shift processing, it is not subject to the limitations of our customary color concept,
