图像处理(如为缩放用户图片、图像和imagecache模块等)，需要类似GD库之类的PHP图形库。
An image library for PHP such as the GD library is needed for image manipulation (resizing user pictures, image and imagecache modules).
该模块利用可变大小的窗口滤波插值进行图像像素重采样，能同时适用整数和分数缩放比例的图像缩放。
The module is designed for both integral and fractional scaling ratios and utilizes variable filter window for calculating pixels of a scaled image to realize pixel re-sampling.
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.
