A low light level image directed to a photocathode in a vacuum causes release of electron which bombard a CMOS imager including passive pixel sensors which in turn generates an electronic image which is fed out of the vacuum and is used to create useful images corresponding to the low level input image. A camera and other low light imaging devices are described.
