CCD versus CMOS Today<\/strong><\/p>\n

<\/p>\n

We have shared our measurement data of the latest CCD and CMOS industrial image sensors.  This includes sensitivity<\/a>, low light performance<\/a>, and MTF<\/a>.   These results show dramatic improvements in image quality of CMOS image sensors and explain the transition to more and more CMOS cameras even for demanding, high-performance applications.<\/p>\n

The figure below presents the sensitivity (QE\/Dark Noise) for two sensors at two temperatures: room temperature, and a higher temperature. The curves show that the CMOS sensor (Sony IMX174) is more sensitive than the CCD sensor (Sony ICX674) at all wavelengths. Also, you can see that the sensors perform worse at higher temperatures than at room temperature, as expected.<\/p>\n

To demonstrate the comparison of low light performance, we shared stills from real time video at Full HD and 60 frames per second of a CCD camera and a CMOS camera (utilizing the same image sensors mentioned before). The light level of 0.3 Lux is just an example; it doesn\u2019t show the limiting light levels of these image sensors. Both images are color-processed; lower light levels can be achieved with monochrome image sensors. We wanted to compare real life situations so the cameras are uncooled and running at full speed around room temperature. The scene is simply a \u201chard to photograph\u201d package materials to show off what can be done.<\/p>\n
