image luminance meaning in English
图像亮度
Examples
- This dissertation introduces a newly white image luminance and chrominance measurement system of color tv in detail , which takes cmos image sensor as its detector and dsp as its kernel processor
本文详细论述了一种新型的彩色电视机白场光色特性检测系统，该系统采用彩色cmos图像传感器作为探测器，用dsp作为核心处理器。 - The experiment results have proved that the measurement system is of high accuracy . the research on crt and non crt white image luminance and chrominance measurement has reached the anticipated demands
经过实际使用，本系统取得了满意的结果，能够同时满足crt彩色电视机和液晶电视白场光色特性的测量要求，达到了研究的预期目的。 - This system is an attempt that to measure white image luminance and chrominance of crt color tv and non crt color tv with cmos image sensor , and then to realize to auto white balance to crt color tv , liquid crystal tv with it
这套系统是利用彩色cmos图像传感器对crt和非crt电视机进行白场测量，继而实现对crt彩色电视机、液晶彩色电视机、各种背投电视进行自动白平衡调整的一个新尝试。 - The other method is to embed a grayscale image watermarking ( which involves the copyright message ) into a color image through considered from the practical application . in this arithmetic , we embed the watermark into the dwt coefficients of color image luminance ( y ) component , so that the color of original image will not be affected . we also employ the multiresolution fusion techniques of the image and adopt the divided method for repeat embeds
二是从实际应用考虑，又进一步研究了如何将标识版权信息的灰度图像作为水印嵌入到彩色图像中，通过讨论图像的颜色模型，提出将水印嵌入到图像yiq模型中的亮度y分量中，这样嵌入水印时，宿主图像的颜色不会受到影响，使水印后图像保持了较好的视觉效果。
