与不熟悉摄像头的朋友在说起摄像头时,第一句话大多是“你那宝贝是多少万像素的?”我说,我的摄像头最廉价,只有30万像素。在琳琅满目的摄像头市场上,35万、37万、48万……或是一款120万像素的摄像头,与30万像素比较,图像的清晰度几乎不分伯仲。因为所谓的120万像素原来只是软件插值将640×480的图片拉大到1024×768了哦。如此虽然输出的图片大了,但图像的质量并没有真正提高。
When talking about a webcam with a friend who is unfamiliar with the webcam, the first sentence is mostly “How many megapixels your baby is?” I said that my webcam is the cheapest with only 300,000 pixels. In an array of camera market, 350,000, 370,000, 480,000 ... or a 120-megapixel camera, compared with 300,000 pixels, the resolution of the image is almost the same. Because the so-called 1.2-megapixel originally only software interpolation will be 640 × 480 picture to 1024 × 768 widened Oh. So although the picture output is large, but the image quality has not really improved.
