Abstract: This paper expounds the three stages ofimaging technology history: electronic machinery, automation and digital stage,including the transition from film type to magnetic recording one, the compatibility between film type and digital type, and the frontier technology of spatial resolution, radiometric resolution, spectral resolution and temporal resolution of digital imaging. We also put forward an automatic control theory for image processing from parts to system, and expound future tendency of imaging technology.

Key words: imaging technology, film, magnetic-record imaging, digital imaging, resolution, automatic control
