摘要： The present invention is directed to a linear image sensor, the electric charge storage time of which can be varied. According to an embodiment of the present invention, there is provided a linear image sensor in which a read-out gate and a charge-transfer gate are disposed on one side of an image sensor array, and a drain gate and a drain region are disposed on the other side of the image sensor array, whereby the electric charge storage time in which a signal charge is transferred by the charge-transfer register after the signal charge is read out by the application of a read-out signal to the read-out gate and the next read-out signal is applied to the read-out gate can be varied by varying the application timing of the drain gate signal. When the linear image sensor is applied to a facsimile, the output level can be adjusted and the light and shade can be controlled by varying the electric charge accumulation time in response to the change of light intensity of a light source or by the change of scan speed of the linear image sensor.

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 digital memory comprises a charge coupled device (CCD) that includes a reference signal storage section. The digital input to the CCD includes an input reference signal and an information signal having a plurality of data levels, for example, a digital "0" and "1". The input reference signal includes a reference bit at the higher data level. The reference signal storage section divides the level of the reference bit to provide a reference level signal halfway between the two data levels. Thus, any shift in the data levels due, for example, to temperature changes in the CCD, affects the reference level signal to the same degree and the reference level can be kept exactly halfway between the data levels.

摘要： A charge coupled device employs peak hold circuits for detecting electric charges transferred through reference registers for facilitating automatic iput bias control. The peak hold circuits are respectively connected to a pair of reference registers which are so designed that one of the reference registers has a given maximum rating and the other reference register is adapted to transfer electric charge having a given fraction of the maximum charge rating of the aforementioned one of registers. The peak hold circuits provide peak values of the outputs of the reference registers to a comparator which feedback controls the input bias of the one of the register. This controlled bias is also applied to an input bias for a signal register which is designed for transferring input electric charge.
