pixel noise variation (a) 无CDS (b) 有CDS3 CMOS Sensor特性 CMOS sensor的本质是计量光电转换事件的线性传感器,在一定意义上可以说是光子计数器,sensor上每个像素的读值都反映了指定时间内该像素捕获光子的数量。一个理想的sensor 应该具备以下一些特性 输出与输入恒成正比(无sensor噪声,只有信号本身的噪声) 输入...

Eric Fossum 和 Sabrina Kemeny一年后Fossum 离开了JPL全职加入Photobit,并邀请到了Georgia Tech 新博士毕业生Dr. Michael Kaplinsky 也加入Photobit 继续推进CMOS sensor 设计,这样一干就是5年,其中的艰辛想必也是不堪回首。最终Photobit 于2001年被美光半导体(Micron Technology)收购,成为了美光的CMOS业务部门,Michael 担...
2003年Dr. Michael Kaplinsky和一位美光同事Dr. Vladimir Berezin 预见到高清CMOS sensor 的时代已经到来,他们必须做点什么,于是他们成立了Arecont Vision公司开始开发高清安防摄像机,Dr. Berezin 拿出了自己大部分积蓄,而Dr. Kaplinsky 向银行抵押了自己的唯一住房以换取40万美金的创业贷款,当这笔钱还剩下4000块的时候...
CMOS 是英文Complementary Metal Oxide Semicondutor 的缩写,这是一种主流的半导体工艺,具有功耗低、速度快的优点,被广泛地用于制造CPU、存储器和各种数字逻辑芯片。基于CMOS 工艺设计的图像传感器叫做CMOS Image Sensor (CIS),与通用的半导体工艺尤其是存储器工艺相似度达到90%以上。 CMOS技术的主要特点是成对地使用PMO...

name says the TTL-sensor that measures the light put out by the flash is metering /through the lens/. This is a big improvement compared to the /auto-thyristor/ mode, because the sensor reading would be correct also when the flash was moved off-camera, placed inside soft-boxes, etc, ...

The readout process for sCMOS however is different, sCMOS sensors are often referred to as “Active Pixel Sensors” (APS) since each pixel has its own amplifier circuit (Figure 1). The overall process is outlined below:Figure 1: The main components of a sCMOS sensor....
