像素是衡量数码相机的最重要指标。像素指的是数码相机的分辨率。它是由相机里的光电传感器上的光敏元件数目所决定的,一个光敏元件就对应一个像素。因此像素越大,意味着光敏元件越多,相应的成本就越大。 数码相机的图像质量是由像素决定的,像素越大,照片的分辨率也越大,打印尺寸在不降低打印质量的同时也越大。早期的数码相机都是低于100万像素的。从1999年下半年开始,200万像素的产品渐渐成为市场的主流。当前的数码相机的发展趋势,像素宛如PC机的CPU主频,有越来越大的势头。
Pixel is the most important measure of digital cameras. Pixels refer to the resolution of a digital camera. It is determined by the number of photosensors on the photo sensor in the camera, and a photo sensor corresponds to one pixel. The larger the pixel, the more light-sensitive elements, the greater the corresponding cost. Digital camera image quality is determined by the pixel, the larger the pixel, the greater the resolution of the photo, the print size without reducing the print quality at the same time the larger. Early digital cameras are less than 1 million pixels. From the second half of 1999, 200 million pixel products gradually become the mainstream of the market. The current development trend of digital cameras, pixels like PC CPU frequency, there is an increasing momentum.
