Analysis of 1/f noise in CMOS APS
bthreshold operation nonstationary 1/f noise model time domain noise analysis CMOS APS image sensor
2015/8/17
As CMOS technology scales, the effect of 1/f noise on low frequency analog circuits such as CMOS image sensors becomes more pronounced, and therefore must be more accurately estimated. Analysis of 1/f...
Analysis of Temporal Noise in CMOS APS
emporal noise subthreshold operation reset noise shot noise CMOS APS image sensor

Temporal noise sets a fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is well studied and characterize...
基于APS-CMOS图像传感器的运动体捕捉方法
运动捕捉 嵌入式系统 有源像素结构CMOS图像传感器 随机接入 数字信号处理
2013/12/10
随着运动体捕捉对嵌入式系统要求的提高，传统方法对分辨率、采集速度难以兼顾.把运动物捕捉分成对分辨率和速度侧重不同的运动检测和目标提取两个部分，利用有源像素结构APS-CMOS图像传感器可随机接入图像缓存的硬件特性,在数字信号处理(digital signal processing, DSP)平台上实现两个阶段特点各异的工作模式切换.这样就使得整个系统的采集速度和目标分辨率同时得到兼顾.而且，此方法...
