公众号记得加星标⭐️,第一时间看推送不会错过。 1. 手机摄像头及市场趋势 疫情过后,由于每部手机摄像头数量的持续增长,CMOS图像传感器(CIS)市场正在缓慢复苏。此 外,为了提供更高质量的图像,人们越来越倾向于采用更高分辨率的摄像头,例如最近的2亿像素摄 像头。为了将更多像素集成到纤薄手机的紧凑尺寸中,像素级的缩小是不可避免的,例如最近推出的 0.5微米深亚微米像素。随着可折叠手机在市场上的普及,对薄型摄像头模块的需求不断增长,这一 趋势将持续下去。 2. 像素光学微缩之旅 从根本上讲,随着像素面积的减小,每个像素的灵敏度也会下降。像素光学架构已经发展到可以增加 信号(接收光子)并降低噪声(光学串扰),使得信噪比(SNR)即使像素缩放也能保持可比性:从 正面照明(FSI)、光导、背面照明(BSI)、背面深沟槽隔离(DTI)到全深度DTI。 尽管架构不断演变,但一微米像素对于主摄像头来说仍然不够,直到合并彩色滤光片技术出现,例如 四像素(2x2),可以在明亮时通过重新镶嵌图像信号处理(ISP)技术提供全分辨率图像,在黑暗 条件下提供更亮的图像。该技术继续向四像素(4x4)延伸,实现0.5微米等深亚微米像素缩 ...
