<P>PROBLEM TO BE SOLVED: To provide an image pickup apparatus which is advantageous for miniaturization and comprises a highly reliable camera shake preventing function, and a solid-state image sensor or the like used therefor. <P>SOLUTION: The present invention employs a CCD 2 which comprises a photo-sensitive part 21 and an accumulation and transfer part 22 provided in a double layer state, a horizontal transfer part 23 and an output part 24 and is capable of performing charge transfer (Z movement) from the photosensitive part 21 to the accumulation and transfer part 22 and intra-plane charge transfer (XY movement) within the accumulation and transfer part 22. Th CCD 2 performs a plurality of times of exposure operations within an exposure time. In each of the exposure operations, charges are accumulated in the photosensitive part 22 and accumulated charges are transferred (Z-moved) to the accumulation and transfer part 22. In parallel, during an exposure operation after the second time, all the charges accumulated in the accumulation and transfer part 22 are XY-moved reversely to the oscillating direction of an apparatus body with the preceding exposure operation so as to form a charge image, with no oscillation, in the accumulation and transfer part 22. Subsequently, the accumulated charges in the accumulation and transfer part 22 are extracted line by line as an image pickup signal via the horizontal transfer part 23 and the output part 24. <P>COPYRIGHT: (C)2007,JPO&INPIT |
