SUMMARY OF THE INVENTION The present invention provides a camera-integrated recording apparatus having a video camera section and a recording section for recording a video signal output from the video camera section. A display signal generating means for generating, a signal synthesizing means for synthesizing a display signal output from the display signal generating means with a video signal recorded by the recording section, and a cassette for a period from the end of the previous recording to the start of the current recording. A first date / time recording request unit for issuing a date / time recording request when the insertion operation is performed, and a date change in a period from the end of the previous recording to the start of the current recording. A second date / time recording requesting unit for issuing a date / time recording request when a date change occurs, wherein at least one of the first and second date / time recording requesting units receives the date / time recording request. In this case, a display signal of the date and time is automatically generated from the display signal generating means for a certain period of time from the start of recording, and synthesized with the video signal by the signal synthesizing means. If no date / time recording request is issued from either of them, a display signal only for the time is automatically generated from the display signal generation means for a certain period of time from the start of recording, and is synthesized with the video signal by the signal synthesis means.

[0007]

When a cassette is inserted between the end of the previous recording and the start of the current recording, a cassette different from the cassette recording the previous date and time may have been inserted. A date and time recording request is issued from the means. If there is a date change during the period from the end of the previous recording to the start of the current recording, this is the first recording of the day, and the second date / time recording requesting unit issues a date / time recording request. When the date and time recording request is issued in this manner, a display signal of the date and time is automatically generated from the display signal generating means for a certain period of time from the start of recording, and is synthesized with the video signal by the signal synthesizing means. A record is made. If there is no cassette insertion operation during the period from the end of the previous recording to the start of the current recording, and there is no date change in the period from the end of the previous recording to the start of the current recording, The second and subsequent records, the first and second
No date / time recording request is issued from the date / time recording requesting means.
When the date and time recording request is not issued in this manner, a display signal of only the time is automatically generated from the display signal generating means for a certain period of time from the start of recording, and the display signal is synthesized with the video signal by the signal synthesizing means. Done.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of this example.

In FIG. 1, reference numeral 1 denotes a video camera unit, the operation of which is controlled by a CPU 2. A horizontal and vertical synchronization signal and a clock are supplied from the video camera unit 1 to the CPU 2 as a synchronization reference signal. CPU2
Is connected to a keyboard 3 for operation. By operating the keyboard 3, adjustment of white balance, setting of shutter speed, and the like are performed. The operation state of the keyboard 3 is displayed on the display 4.

A video signal SV output from the video camera unit 1 is supplied to a VTR unit 6 via a synthesizer 5. The operation of the VTR unit 6 is controlled by the CPU 2. That is, operations such as recording, fast forward, and rewind are controlled by operating the keyboard 3. A cassette sensor 7 for detecting the presence or absence of a tape cassette is connected to the VTR unit 6, and a detection output of the cassette sensor 7 is supplied to the CPU 2.

In this embodiment, the date and time can be recorded at an arbitrary timing by a manual operation, and the date and time can be automatically recorded by setting an automatic recording mode by operating the keyboard 3.

The CPU 2 has a timer 2a and a character generator 2b. When the automatic recording mode is set and the date and time are recorded, the display data corresponding to the date and time data of the timer 2a is output from the character generator 2.
b, and this display data is stored in the graphic RAM 8
Is written to. Then, in synchronization with the video signal SV, R
The display data is repeatedly read from the AM 8, converted into an analog signal by the D / A converter 9, and supplied to the synthesizer 5.

FIG. 2 is a flowchart showing the date and time recording process. First, it is determined whether or not a tape cassette is present at the cassette mounting position of the VTR unit 6 (step 1).
1). If there is a tape cassette, a time recording request is set (step 12).

If it is determined in step 11 that there is no tape cassette, it is determined whether a tape cassette has been inserted into the cassette mounting position of the VTR unit 6 (step 13). If the tape cassette is not inserted, the process returns to step 11, and if the tape cassette is inserted, a date and time recording request is set (step 14).

In this state, when the recording switch provided on the keyboard 3 is turned on (step 15), it is first determined whether or not the date has changed (step 16). In this case, the determination is made by comparing the date with the date determined previously. If the date has changed, a date and time recording request is set (step 17). On the other hand, if the date has not changed, the process proceeds to step 18.

Next, it is determined whether or not the mode is the automatic date and time recording mode (step 18). When the automatic recording mode is set by operating the keyboard 3, it is determined whether a date and time recording request is set (step 19). When the date and time recording request is set, the display signal of the date and time is synthesized with the video signal SV for a certain period of time, for example, several seconds, and recorded (steps 20 and 21).

In this case, after the CPU 2 writes the display data of the current date and time into the RAM 8, the display data is repeatedly read from the RAM 8 for a certain period of time. Then, the display signal output from the D / A converter 9 is combined with the video signal SV by the combiner 5, and the combined video signal SV of the display signal is supplied to the VTR unit 6 and recorded. The image based on the video signal SV in which the display signal is synthesized in this manner is a superimposed character indicating the date and time in a part of the image.

Next, the date and time recording request is reset (step 22), and the time and date recording request is reset (step 23). Then, it is determined whether or not the recording switch is off (step 24). Step 1 when off
Returning to step 1, if not off, return to step 16.

If the date and time recording request is not set in step 19, it is determined whether or not the keyboard 3 is operated to set the automatic time recording mode (step 25). Step 22 when not in the time automatic recording mode
Proceed to. If the automatic time recording mode is set, it is determined whether a time recording request is set (step 26). If the time recording request has not been set, the process proceeds to step 24. If the time recording request has been set, the process proceeds to step 21, where a display signal for a certain period of time, for example, several seconds, is combined with the video signal SV and recorded.

If it is determined in step 18 that the automatic date and time recording mode is not set, the date and time is recorded based on a manual operation (step 27), and the flow advances to step 22.

This embodiment is configured as described above, and the VTR unit 6
When the tape cassette is not mounted at the first cassette mounting position and is inserted thereafter, a date and time recording request is set. Therefore, if the automatic date and time recording mode is set by the keyboard 3, the display signal of the date and time is combined with the video signal SV for a certain time after the recording switch is turned on to start recording, and the date and time are automatically set. Is recorded.

When a tape cassette is initially mounted at the cassette mounting position of the VTR section 6, a time recording request is set. Therefore, if the time automatic recording mode is set by the keyboard 3, a time display signal is synthesized with the video signal SV for a certain period of time after the recording switch is turned on to start recording, and the time is automatically recorded. It is. That is, when recording is performed many times while the same tape cassette is mounted in the cassette mounting position, the time is automatically recorded every time the recording switch is turned on.

Also in this case, when the date changes, a date and time recording request is set. Therefore, if the keyboard 3 is set to the automatic date and time recording mode, the date and time are automatically recorded for a certain period of time after the recording switch is turned on to start recording.

When recording is performed with the recording switch turned on and the date changes, a date and time recording request is set. Therefore, if the date and time automatic recording mode is set on the keyboard, the date and time are automatically recorded for a fixed time after the date changes.

As described above, according to this embodiment, by setting the automatic date and time recording mode or the automatic time recording mode, the date and time are recorded automatically at the timing when it is deemed necessary to record the date and time. Therefore, the usability of the user can be improved.

[0026]

According to the present invention, based on the presence or absence of a cassette insertion operation and a change in date during the period from the end of the previous recording to the start of the current recording, a certain period of time from the start of the recording is obtained.
This function automatically records the date and time.Even if the user does not need to perform manual operation, the date and time are automatically recorded when it is deemed necessary to record the date and time. Can be recorded to improve usability.
