DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. As an embodiment of the present invention, a camera-integrated VTR is taken as an example. FIG. 1 is a diagram showing a configuration of a camera-integrated VTR according to the present invention.

[0007] The optical signal input through the lens is converted into an electric signal by the image pickup device, and a video signal is generated in the signal processing circuit 1. The generated video signal is input to a mixing circuit 2 for mixing the video signal with an audio signal.

[0008] The video signal mixed with the audio signal in the mixing circuit 2 is input to a recording and reproduction processing circuit 3, encoded for recording, and recorded on a recording medium 4. The recording medium 4 may be any medium such as a tape medium, a disk medium, and a memory.

The audio data is stored in an audio memory 8. The memory for the audio data may be a small memory card or MD. FIG. 2 shows a recording state of audio data in the audio memory 8.

As shown in FIG. 2, audio data is divided into a plurality of parts, so-called songs. Here, part 1 is recorded for 20 seconds from the beginning, part 2 is recorded for 70 seconds thereafter, and so on. In fact, in such audio data, a signal indicating the end of each part is stored at the end of each part, and each signal is constituted by this signal. Also, how much time each part has, and the title of the music or the like may be recorded as index information at the beginning of the audio memory 8 or the like. With such index information, the time of each part can be immediately displayed on the display unit as shown in FIG.

The audio data stored in the audio memory 8 is controlled and read by the CPU 6. Also CPU
Reference numeral 6 also controls the recording mechanism 5 that performs recording control when performing recording on the recording medium 4 described above. Here, since the recording medium 4 is assumed to be a tape medium for performing digital recording, the recording medium 5 is provided. However, if the recording medium 4 is a medium such as a memory card, it becomes a simple recording control unit. . The working memory 7 is a working memory of the CPU 6.

Digital video tape recording system (DVC)
Will be described as an example. FIG. 3 shows a recording format of a tape recorded by the helical scan method. Audio is recorded from the lower part of the tape in the figure, a track number is recorded thereon, and a video is recorded on the information.

[0013] The helical scan method recorded in this way requires special processing when performing continuous shooting. This will be described with reference to FIG. In the tape running (REC RUN) state during recording, video and music are normally recorded. In this state, the end of one PART of music (t)
Then, the CPU 6 stores the final recording track number n in the working memory 7, and then stops the tape running. At this time, as shown in FIG. 5, the recorded tracks include not only the video tracks,..., N-3, n-2, n-2, n tracks, but also the music tracks,. Recorded as -1, t. Then the CPU
In step 6, the tape is made to travel in the reverse direction by the recording mechanism and stopped again.

When a recording start operation instruction is given again, the CPU 6 causes the tape to run in the normal rotation direction.
At this time, the servo is started up so as to match the phase with the track of the recording tape, and the next recording is started when the track number n stored in the memory is reached.

At this time, considering the rise delay of the circuit,
The operation of the audio data is also started before the recording, so that the recording of the video to n + 1 can be performed simultaneously with the recording of the video to n + 1. In this way, seamless connection processing can be performed.

The overall processing flow will be described with reference to the flowchart of FIG. Here, it is assumed that a memory card on which audio data is already recorded and a recording tape for recording a video are mounted on the main body. Further, when the memory card is inserted into the main body, the end time (or address) of each part has already been read from the index data in the memory card and stored in the working memory 7.

In step S1, a recording start instruction is given by the switch SW shown in FIG. In step S2, the parts are set, and in step S3, the running of the tape as the recording medium is started. In step S4, the audio data reproduced from the audio memory and the video data input from the image sensor are recorded.

In step S5, the end of the voice part is detected. Here, the recording is continued in step S4 until the end of the part is detected. At this time, as shown in FIG. 7, it is also possible to display the recording part and the recording time.

When the end of the part is detected in step S5, the reading from the audio memory is stopped in step S6, the track number on the recording medium is stored in the working memory in step S7, and the recording medium is stored in step S8. Stop. In step S9, as described above, the connection processing for slightly rewinding the recording medium is performed.

In step S10, it is detected whether all parts of the audio memory have been completed. If all parts have been completed, the entire process is completed. If there are remaining parts, a restart instruction is waited for in step S11. If a restart instruction is issued, the running of the recording medium is started in step S12, and the track number recorded at the time of interruption is detected in step S13. If it is detected, the process returns to step S4 from that position to record audio and video.

By repeating such processing, it becomes possible to record a video signal in accordance with each part recorded in the audio memory.

[0022]

According to the present invention, audio data is read from an audio memory in which audio data composed of a plurality of parts is recorded in advance, video data is recorded, and video recording is automatically stopped at the joint of the audio data. With such a configuration, when creating a promotion video or the like using previously recorded audio data, there is an effect that it is not necessary to edit the video in accordance with the audio.
