megapixel

　　5.More megapixels always means a better camera

　　像素约高摄像头越好

　　What’s the difference between 12 megapixel cameras and 8 megapixel cameras? Not much, as it turns out. The quality of an image is determined in large part by how much light the sensor is able to take in. Bigger sensors may come with larger pixels, and the larger the pixel the more light it can absorb. So, it’s really the size of the pixels that matter as much or more than the sheer number of pixels. (A megapixel is simply shorthand for a million pixels.)

　　1200万像素的摄像头与800万像素的摄像头二者区别何在?事实证明，其实没什么区别。图片的质量很大程度上取决于传感器采入的光线的多少。传感器越大，相匹配的像素可能更高，像素越高，采光就越多。因此，重要的是传感器的尺寸，传感器的尺寸与像素的高低同等重要，或者说比后者更重要。
