PROBLEM TO BE SOLVED: To provide a CCD image pickup device which can make the generation of an index picture easier and can be increased in image picking-up and processing speeds, a method for driving the device, and a film scanner applying such a technology. SOLUTION: A CCD image sensor 30 is constituted in such a structure that the transfer gate electrodes V1(TG1A) and V3(TG3A) on one photoelectric conversion element line which is the closest to a horizontal transfer CCD 36 of two-dimensionally arranged plural photoelectric conversion elements 32 or on its adjacent two photoelectric conversion element lines are independently controlled separately from the other photoelectric conversion elements. The image sensor 30 is mounted on a film scanner and, at the time of performing a a picture reading process (at the time of scanning index) for acquiring an index picture, the sensor 30 is functioned as a linear image sensor and, at the time of performing a proper image picking-up process for acquiring high-quality pictures at every frame, the sensor 30 is functioned as an areal image sensor. |
