Apparatus for determining charge/voltage conversion ratios in charge coupled devices |
摘要 |
A method for determining a charge/voltage conversion ratio of a solid state image pickup element with an electronic shutter function which is capable of transferring signal charge accumulated in a photosensitive portion to a substrate. A voltage of a predetermined first level is applied to the substrate to measure an output voltage at an output portion, and then a voltage of a second level higher than that of the first level is applied to the substrate to measure a current flowing through the substrate, thereby obtaining a charge/voltage conversion ratio in accordance with a ratio between the measured output voltage and the measured current.
