摘要
计算机中图像颜色处理技术是根据RGB三原色理论对色彩信息量化 ,再利用像素的点运算扫描整幅图像进行一一处理。处理带调色板的图像根据其结构特点 ,改变调色板的颜色数据为灰度数据即可 ,而真彩色图像可以直接对图像数据部分进行取灰度值进行处理 ;并在VC + + 6.0环境下编制程序实现 ,试验结果表明充分利用调色板技术进行灰度处理 ,优点明显 ,适应性强 ,用途广泛。
Image color-process techniques is to digitize the color information based on RGB principle, then to scan and process the whole image by means of computation of pixel. Regarding the procession of images with palette, it could be done by changing the color data of palette into the gray-value in terms of its storage structural feature. Meanwhile, the true-color image can be processed by choosing gray-value directly , which can be realized by programming under circumstance of VC++6.0. It can be concluded from experiment that there are many advantages to utilize the technique of palette to gray color image, which is practicable and used widely.
