Abstract

PURPOSE:To remove the running of an image at the time of panning, by providing a storage means which reads out a stored video signal repeatedly during the operating period of an operating switch, and a switching means which outputs the video signal read out by the storage means in stead of the output video signal of an operating means during the operating period of the operating switch. CONSTITUTION:A part of the video output of an image pickup means 2, after being impressed on an A/D converter 5, and converted to a digital signal, is impressed on a storage control circuit 6. A read out video signal, after being converted to an analog video signal, is impressed on the contact (b) of a change- over switch 3 by a D/A converter 9. In an ordinary image pickup state, the video signal and a voice signal from the image pickup means 2 and a voice collection means 10 are recorded on a magnetic tape in order if no operating switch 8 is operated. And if the operating switch 8 is operated prior to panning at the time of panning, the change-over switch 3 is switched from a contact (a) to the contact (b), and the video signal at the time of operating the operating switch 8 is recorded repeatedly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an imaging device, a so-called video camera, that sequentially converts an optical image of a subject into a video signal. This is intended to reduce and eliminate the occurrence of blurred images.

BACKGROUND ART When a video signal output from a video camera is recorded on a VTR, an audio signal is also recorded at the same time. As shown in Figure 2, when photographing subject B from a state where video camera 1 is photographing subject A, in other words, when the video camera is panned quickly, the VT
The reproduced image of R is a flowing image. To solve this problem, pan the video camera while temporarily stopping recording on the VTR, and then turn on the VTR's recording switch again. The playback image will instantly change from subject A to subject B, and when panning, The image streaming problem is resolved.

Problems to be Solved by the Invention However, such an arrangement has the disadvantage that the audio disappears during panning.

The present invention seeks to eliminate image flow during panning without interrupting the audio signal.

Means for Solving the Problems The imaging device of the present invention includes an imaging device that sequentially converts an optical image of a subject into a video signal, and a video signal of one screen of the video signal stored in accordance with the operation of an operation switch. storage means for manipulating and reading out the stored video signal during the operation period of the operation switch; and outputting the video signal read by the storage means in place of the output video signal of the operation means during the operation period of the operation switch. and a switching means for.

Function According to the above configuration, if you operate the operation switch just before panning from the state where subject A is being photographed, the VTR
The signal sent to the VT will be the video signal that was being shot at the moment the operation switch was operated, and during panning, the signal will be sent to the VT as a still image.
When the camera is pointed at the position where subject B is recorded and subject B is recorded, when you stop operating the control switch, the still image changes to a video showing subject B, but the VTR continues to record, so the audio signal during panning. It is possible to obtain an image with no interruptions and no screen drift due to rapid panning, which solves the problems associated with conventional panning.

Example An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 2 denotes an imaging means consisting of an image pickup tube or the like that sequentially converts the optical image of the subject into a video signal.
It is connected to a recording circuit system 4 of the VTR via a changeover switch 3 connected to the VTR.

A part of the video output from the imaging means 2 is applied to the A/D converter 6, converted into a digital signal, and then applied to the storage control circuit 6. This memory control circuit 6
Normally, the latest video signal for one screen (one field or one frame) of the digitized video output from the A/D converter 6 is sequentially stored in a semiconductor memory (RAM).
) 7, and when a command signal is applied by operating the operation switch 8, new storage operations are stopped until the command signal disappears, and the video signal of one screen is recorded when the command signal is applied. is read out from the semiconductor memory means 7. The read video signal is converted into an analog video signal by the D/A converter 9 and then applied to the b contact of the changeover switch 3. Further, the changeover switch 3 is configured to switch to the contact position during the operation period of the operation switch 8. Note that 1Q is a sound collecting means such as a microphone, and the sound output is applied to the recording circuit system 4 and recorded on the magnetic tape together with the video signal by conventionally known means.

In the above configuration, in the normal imaging state, if the operation switch 8 is not operated, the imaging means 2 and the sound collecting means 1
The video and audio signals from o are sequentially recorded on a magnetic tape. Then, when panning, if you operate the operation switch 8 before panning, the changeover switch 3 will change to a.
The contact is switched to the b contact, and the video signal when the operation switch 8 is operated is repeatedly recorded.

After panning is completed, when the operation of the operation switch 8 is stopped, the changeover switch 3 is switched to the a contact again, and normal recording can be performed.

Effects of the Invention As described above, according to the present invention, when panning the camera, the image before panning is recorded as a still image, so the image does not flow during panning. The audio signal can be recorded without interruption.
