Charge transfer device having a signal processing circuit for correcting output voltage |
摘要 |
A charge transfer device includes a circuit which can correct a fluctuated amount of light (charge amount)-output voltage characteristic with accuracy even when fluctuated by the change of temperature and the fluctuation of a power supply voltage. An output voltage characteristic in the standard state corresponding to a reference charge is stored and held in a ROM in advance. An ALU (arithmetic logical unit) corrects the light (charge amount)-output voltage characteristic by using the output voltage characteristic in the standard state corresponding to the reference charge stored in the ROM and the output voltages corresponding to the reference charge inputs from reference charge input portions in an imaging state, and corrects an output voltage (Va) corresponding to a signal charge in a practical imaging state.
