能有效抵抗信号处理又能抵抗几何攻击是当今数字水印研究的热点和难点之一，提出一种能够抵抗信号处理、旋转、缩放和平移的鲁棒视频水印。
The watermarking technique robust to both signal processing attacks and geometrical attacks is one of the hotspots and difficulties in the digital watermarking research.
合并了数字照相机的照相机模块优选地还包括嵌入图像信号处理器，使得照相机模块被配置为产生缩放的输出图像。
A camera module incorporating the digital camera preferably also includes a built in image signal processor, such that the camera module is configured to produce scaled output images.
另一方面，非本土的信号延迟大约70毫秒，或4张，由于投影机的需要重新缩放图片。
On the other hand, non-native signals were delayed about 70 milliseconds, or 4 frames, due to the projector's need to re-scale the image.
