ある。Means for Solving the Problems The present invention provides an imaging means that sequentially converts an optical image of a subject into a video signal, and a light that illuminates the subject in synchronization with a synchronization signal of the imaging device in response to operation of an operation switch. a light flashing device that periodically flashes the light; and a memory that sequentially rewrites and stores one screen of video signals captured by the imaging means while the light is turned on in synchronization with the lighting of the light. The image pickup apparatus includes a means for repeatedly reading a video signal of one screen stored in the storage means until the next video signal is rewritten, and outputting the video signal as an output video signal.

トが点灯している間は、ビデオカメラに入ってくる被写
体の照度は十分に大きい。Effect According to the above configuration, when the light is turned on when photographing a dark place, the light blinks every few seconds. While the light is on, the illuminance of the subject entering the video camera is sufficiently high.

なる。By storing one field of the video signal taken at high illuminance and repeatedly outputting this stored signal while the light is off, a system strobe-like video can be created. By doing this, the power consumption is significantly lower than that of a light that is kept on.
It becomes possible to draw current from the video camera battery.

イト１２を点滅せしめるよう構成されている。In FIG. 1, reference numeral 2 denotes an imaging means comprising an imaging device or the like that sequentially converts an optical image of a subject into a video signal, which is normally outputted via a changeover switch 3 to which contacts are already connected. Further, a part of the video output of the imaging means 2 is
The signal is applied to the D converter 4, converted into a digital signal, and then applied to the storage control circuit 6. This memory control circuit 5 responds to the application of a command signal S, which will be described later, to
It operates to sequentially store the video signal of the latest one screen (one field or one frame) of the digitized video output of the converter 6 in the semiconductor memory means (RAM) 6, and after storing, the stored video The signal is repeatedly reproduced and applied to the contacts of the switch 3 via a D/mu converter. Reference numeral 11 denotes an operation switch for lighting the light. In conjunction with the operation of this operation switch 11, the switch 3 switches to the contact point, and the command signal generation circuit 8 generates a command signal (Fig. 2b). )
is configured to occur. This command signal is transmitted over several field periods T with predetermined synchronization (for example, several seconds).
has a pulse width of This command signal is applied to the memory control circuit 6 to control the memory readout of the RAM 6, and is also applied to the light blinking control circuit 91C to connect the power source 1o and the light 12 only during the period of the pulse width τ, The light 12 is configured to blink.

When the illuminance is low, when the operation switch 11 is turned on, the output a causes the switch 3 to switch to the contact point. The output a is applied to a command signal generating circuit 8, which generates a command signal S. This command signal causes the light 12 to be turned on only during the pulse width T of the command signal. Therefore, the video output C of the device 2 becomes high only during the lighting period of the light 120. This high output video output for one screen is gated by the storage control circuit 5 and stored in RAMe, and the stored video signal is repeatedly read out as a continuous signal d until the next new signal is stored.
