为了探索像素与像质的之间关系,本刊编辑专门采访了我国著名数字图像专家钱元凯先生。Q:目前1/2.5和1/1.7英寸的感光元件所能容纳的像素似乎已经到了极限,那么4/3系统、APS-C、全画幅、中画幅相机的像素是否还有增长的空间?A:像素是否能够继续攀升是由光学衍射极限和镜头分辨率极限来决定的,目前来说主要是小光圈下 In order to explore the relationship between pixel and image quality, our editors interviewed Mr. Qian Yuankai, a famous digital image expert in our country. Q: At the moment when the 1 / 2.5 and 1 / 1.7 inch sensor seems to have reached the limit, is there any room for growth for the 4/3 system, APS-C, full frame, and medium format cameras? A : Whether the pixel can continue to climb is determined by the optical diffraction limit and the resolution limit of the lens, for the moment it is mainly a small aperture
