  • Patent number: 5557327
    Abstract: An image input apparatus includes a picture-taking optical system, a facial imaging device, a transparent parallel flat plate member arranged in an optical path of the optical system approximately in parallel with a picture-taking surface of the imaging device, a tilting member to tilt the transparent member with respect to the imaging device so that the image formed on the imaging device is moved, a memory to store each image moved when the transparent member is tilted, and an image synthesizer to synthesize an image of high resolution from the image stored in the memory. Three points not aligned on a straight line are selected from the transparent member, and one point is used as a support point and other two points are used as operation points so that the tilting member is operated through these support and operation points.

  • Patent number: 5148210
    Abstract: An automatic focusing device for driving an optical system to focus on a subject. The device has a CCD to read an image of the subject, a driver for the CCD so that a first image signal is outputted from the CCD in a normal direction and a second image signal is outputted from the CCD in a reversal direction, the optical system to form the image on the CCD, and a controller to control the optical system in accordance with the first image signal and the second image signal so that the optical system forms the image on the CCD in focus.

  • Patent number: 5107336
    Abstract: An image reader for panning a camera view to a movable subject. The image reader has a CCD to scan an image in a horizontal direction and a vertical direction, and the CCD outputs image signals in a normal direction and a reversal direction. The image reader also has a circuit to determine a position of the movable suject according to the image signals in the normal direction and the reversal direction, and controls the camera view according to the position of the movable subject.

  • Patent number: 4600949
    Abstract: A video camera comprising an image-forming lens system having an optical axis and a light-beam splitting means capable of splitting an incident light-beam from the image-forming lens system into a primary optical path along the optical axis and leading into a view finder means, and a secondary optical path bent at an angle to the primary optical path and leading into an electrical image-receiving means. There is provided a camera tube in the bent optical path and a view finder in the straight optical path. An electrical circuit means comprising printed circuit boards is arranged in a U-shape manner to cover three sides of the light-beam splitting means other than the side facing the secondary optical path.
