摘要： A video camera includes a viewfinder through which an operator may view an image of an object to be videoed, a rotatably supported head-carrier cylinder and a capstan for transporting a length of magnetic recording medium. This video camera also includes at least one of first and second detecting units for detecting a change in rotation of the rotary head-carrier cylinder and for detecting a change in rotation of the capstan, respectively, and a determining unit operable to determine, in reference to information supplied from at least one of the first and second detecting units, whether or not a video recording then taking place is in accordance with the will of an operator. The video camera may be provided with at least one of a camera wobbling detector and an eye sensor for detecting whether or not the operator looks through the viewfinder and, in such case, the determining unit makes the determination in reference to information supplied from one of the camera wobbling detector and the eye sensor and that from at least one of the first and second detecting units.

摘要： A facsimile bandwidth compression method using a facsimile signal comprising a synchronizing signal part, a control signal part having digital signals made by coding signals of existence or non-existence of substantial picture information in blocks which are made by dividing the picture information signal into a specified uniform length segment, and a picture information part consisting of picture information signal of the blocks containing at least one black picture element. A reference signal having an inverted carrier phase from that of the synchronizing signal part is inserted between the synchronizing signal part and the control part. The coding of the digital signal is made by inverting the carrier phase. Guard bands having specified levels are inserted between the blocks, thereby assuring more accurate and fine synchronization than the known WBS (white block skipping) art, and hence, a very clear reproduced picture.
