| 摘要 |
The present invention intends to improve a difference between signal levels of odd-numbered pixels and even-numbered pixels in a CCD (charge coupled device) linear sensor. In a CCD linear sensor comprising a sensor region (1) having an array of a plurality of sensor elements (pixels) (S1), (S2), ... and first and second horizontal transfer registers (4) and (5) disposed on the respective sides of the sensor region (1) through read-out gate sections (2) and (3) wherein signal charges of every other sensor elements (S1), (S3), (S5), ... are transferred by the first horizontal transfer register (4) while signal charges of remaining every other sensor elements (S2), (S4), (S6) are transferred by the second horizontal transfer register (5), the first and second horizontal transfer registers (4) and (5) include first and second transfer electrodes (22R1), (22R2) to which two-phase drive pulses ( phi H1) and ( phi H2) are applied, respectively and electrode configurations at the read-out gate section side are formed substantially the same,whereby the capacity of a first transfer section (HR1) to which the drive pulse ( phi H1) is applied is made equal to that of a second transfer section (HR2) to which the drive pulse ( phi H2) is applied. <IMAGE> |
