摘要： A solid state imager device such as a CCD imager device includes a timing generator which generates and supplies a clamping circuit with, a clamping pulse for clamping a first signal, corresponding to one pixel, from a through region of a CCD shift register, and a clamping pulse for clamping a second signal, corresponding to one pixel, from an optical black region of a sensor array. Specifically, the clamping pulse for clamping the first signal clamps a signal, corresponding to a first pixel, from the through region, and the clamping pulse for clamping the second signal clamps a signal, corresponding to a second or following pixel, from the optical black region. An output signal from the clamping circuit is supplied to an A/D converter which converts the supplied signal at such timing as not to sample the signal, corresponding to the first pixel, from the through region.

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.

摘要： A control circuit generates a control signal which is of a low level during a certain period of time after the power supply of a solid state imager has been turned on or a power save mode thereof has been canceled, and of a high level after elapse of the period of time. Based on the control signal, a timing generator generates transfer clock signals having a high frequency than when the solid state imager is in a normal transfer mode, and applies the transfer clock signals to a CCD shift register to remove or transfer excessive invalid charges at a high rate therefrom. After the power supply has been turned on or the power save mode has been canceled, therefore, the time required to bring the solid state imager into a condition capable of imaging a subject is shortened.
