Abstract:
1. A driving method of a MOS sensor having a plurality of pixels in an image pick up unit, each of said pixels comprising: a reset transistor; a photoelectric conversion element having a first terminal connected to one of source or drain terminals of said reset transistors, and a second terminal connected to a photoelectric conversion clement side power source line; a reset signal line connected to a gate terminal of said reset transistor; a signal amplifier circuit having an input terminal connected to said one of the source or drain terminals of said reset transistor; a reset side power source line connected to other one of the source or drain terminals of said reset transistor; said method comprising the steps of: imaging a first object on trial, comprising the steps of: determining a storage period in accordance with a period from the time of said resetting to a time when the signal of the selected pixels saturate; and imaging a second object ordinarily, comprising the steps of:
