  • Patent number: 5146353
    Abstract: A still video camera provided with a mode selector to select an operation mode, a trigger generator to generate a trigger signal and a video recorder to record a visual image of the subject and to reproduce the recorded image. When the record-play mode is selected by the mode selector, the video recorder responds to the trigger signal from the trigger generator to record a frame of the visual image of the subject. The recorded frame of the visual image of the subject is then played back. This sequence can be repeated at the direction of the operator, at predetermined time intervals, or in response to a sound amplitude greater than a predetermined level. The still video camera is also capable of recording and playing back sound to accompany the still picture.

  • Patent number: 5130804
    Abstract: An image recording apparatus for converting a subject image to an image signal and storing the image signal in a memory. An optical unit for focusing the subject image on a focal plane is fixed to obverse surface of a circuit board concentric to an opening of the circuit board that is formed as an optical path through the depth of the circuit board, and an image sensor is fixed to reverse surface of the circuit board concentric to the opening. A sensing surface of the image sensor is directed to the optical unit and is coincident with the focal plane of the optical unit.
