发明名称 Asynchronous still timing for a video camera producing movie or still images
摘要 A still video camera produces a movie image for previewing in an electronic viewfinder according to a specific image repetition rate and a still image for recording on a magnetic disk. In the movie mode, video signals are clocked from a solid-state, interline transfer image sensor by application of driving signals from a movie timing generator. The still mode interrupts the movie timing with a special driving signal from a still timing generator. By initiating the still exposure in synchronism with the high frequency movie driving signals that operate the image sensor . . . and not with regard to the vertical drive interval determining the image repetition rate . . . a "pseudo"-asynchronous relationship can be obtained with the movie mode and the still exposure can begin without noticeable delay. After the still exposure is completed, control of the image sensor is returned to the movie timing generator in synchronism with the image repetition rate.
