A CCD image sensor and an imaging system, which can change their movements to adapt to various shooting conditions, have been developed by utilizing characteristics of human eyes as hints. They are a switchable system between Wide dynamic range mode, High sensitivity mode and High resolution mode. As a result of this, the most suitable mode for the shooting conditions can be selected, like human eyes.
