ccd sensor noise vs cmos sensor noise Digital noise is one of the biggest concerns of photographers who shoot in low levels of light. Because CCD sensors have more sensitivity to light, the signal does not have to be amplified as much. Generally speaking, CCD camera sensors produce less noise...
CRA与像素在传感器的位置是相关的。如果lens的CRA小于sensor的CRA,一定会有偏色现象。 10、动态范围:测量了图像传感器在同一张照片中同时捕获光明和黑暗物体的能力,通常定义为最亮信号与最暗信号比值的对数。 11、IR cut(滤除红外光) 如果没有,图像就会明显偏红,这种色差是没法用软件来调整的。 12、快门 Global ...
One simplified way to think about the sensor used in a digital camera (or camcorder) is to think of it as having a 2-D array of thousands or millions of tiny solar cells, each of which transforms the light from one small portion of the image into electrons. Both CCD and CMOS devices ...
图像传感器按技术原理通常分为CCD(Charge-Coupled Device,电荷耦合器件)、CMOS(Complementary Metal Oxide Semiconductor,互补金属氧化物场效应管)和CIS(Contact Image Sensor,接触式图像传感器)、ToF 3D Image Sensors(Time of Flight 3D Image Sensors,3D-ToF 图像传感器)和TIS(Thermal Image Sensor,热敏图像传感器)五种...

CCD(Charge Coupled Device)图像传感器(以下简称CCD)和CMOS图像传感器(CMOS Image Sensor以下简称CIS)的主要区别是由感光单元及读出电路结构不同而导致制造工艺的不同。CCD感光单元实现光电转换后,以电荷的方式存贮并以电荷转移的方式顺序输出,需要专用的工艺制程实现;CIS图像感光单元为光电二极管,可在通用CMOS集成电路工艺...
