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.

A still video camera of the type having an image sensor that generates a charge pattern in response to image light from an object and operates thereupon either as a signal source for a movie image, according to a specific image repetition rate, or as a signal source for a still image, the camera further including a release switch for initiating a still exposure period, said camera comprising: means for generating a continuous stream of movie phasing signals for operating upon the charge in the image sensor at a rate that is substantially greater than the image repetition rate; transfer means for applying said movie phasing signals to the image sensor when the image sensor operates as a signal source for a movie image; means for generating a still phasing signal for operating the image sensor as a signal source for a still image; and means responsive to actuation of the release switch for interrupting the application of said movie phasing signals to the image sensor and for substituting therefor said still phasing signal synchronously with respect to said movie phasing signals and asynchronously with respect to said image repetition rate.
