  • Patent number: 7400023
    Abstract: In a photoelectric converting film stack type solid-state image pickup device, a plurality of photoelectric converting film are stacked on a semiconductor substrate in which a signal readout circuit is formed, each of the photoelectric converting films is sandwiched between a common electrode film and pixel electrode films corresponding to respective pixels, and photo-charges generated in the photoelectric converting films are taken out through the pixel electrode films. In the solid-state image pickup device, a common electrode film for a first photoelectric converting film is used also as a common electrode film for a second photoelectric converting film, the first photoelectric converting film is stacked below the common electrode film, and the second photoelectric converting film is stacked above the common electrode film.

  • Patent number: 7330212
    Abstract: A drive controller of a lens apparatus including a first lens unit movable to perform manual focus and a second lens unit disposed closer to an image than the first lens unit. The drive controller includes a detection device detecting a focal state of the lens apparatus, a storage device storing the detected focal state, and a control device controlling focus by driving the second lens unit to a focal position based on the detected focal state. The control device performs a compensation operation on the manual focus with the focus control after completion of the manual focus. The drive controller eliminates a clutch mechanism for selecting drive systems for the manual focus and focus adjustment and performs a focus adjustment (a compensation operation) after completion of the manual focus while minimizing a space needed for a rear focus unit to move.
