Description

  The present invention relates to a recording apparatus capable of recording an input signal and a time code on a required recording medium, and a time information setting method in such a recording apparatus.

Japanese Patent Laid-Open No. 5-189940

For example, when recording video data on a recording medium as a recording apparatus, particularly a professional video recording apparatus, time information as a time code is recorded for each frame image in the video. For example, a unit called a frame is provided in the lower digits of hour, minute, and second, and time information such as n hours, m minutes, 1 second, and k frames is recorded as a time code.
As an example, when the NTSC (National Television System Commitee) system is adopted as the video data standard, the frame digit value is counted one by one with a frame period of 59.94 Hz, and the frame digit value is counted. Each time 30 is counted, the second digit is incremented by one.

  Here, there is a demand for recording time information based on real time (current time) as such a time code. That is, the time code is recorded by adding the above-mentioned digit of the number of frames to the lower digit of the second digit of the real time information.

In order to meet such a demand, the conventional recording apparatus is provided with a time code generator capable of time counting with the 59.94 Hz frame period as described above and a real-time timer unit for measuring real time. In some cases, real-time information measured by a real-time timer is set in a time code generator in response to a predetermined operation input (see, for example, Patent Document 1 above).
Thus, when recording the time code based on the real time, for example, the user can manually save the time by manually sending a numerical value and adjusting the time information of the time code generator to the real time. .

  Here, the conventional recording apparatus is provided with a dedicated operator for automatically setting the real-time information in the time code generator by the real-time timer as described above. That is, the user can set the real time counted by the real time timer by operating the dedicated operator. Accordingly, the user can operate the dedicated operation element so that the time code based on the real time is recorded on the recording medium together with the video data.

  However, for example, when a portable type recording apparatus is assumed, the space for mounting the operators is relatively small, and the number of operators that can be mounted is limited. Considering this, it is preferable that the number of operation elements can be reduced as much as possible.

Therefore, in the present invention, in view of the above problems, the recording apparatus is configured as follows.
That is, a time code generating means for generating a time code for each predetermined time, a recording means for recording the input signal and the time code on a required recording medium, and a real time timing means for measuring the real time are provided.
Also provided is a display means, an operation means provided with a numerical value feed operator capable of performing a numerical value feed operation for sending a numerical value displayed on at least the display means, and a calculation means.
And the said calculating means is
When a numerical value other than a predetermined predetermined numerical value is displayed on the display means, the numerical value displayed on the display means is controlled based on the operation of the numerical value feed operator, and the display When the predetermined numerical value is displayed on the means, a display control process for controlling the predetermined information to be displayed on the display means based on the operation of the numerical value feed operator;
If the predetermined information is not displayed on the display means when the display content of the display means is to be confirmed, time information based on a displayed numerical value is set for the time code generation means. When the predetermined information is displayed on the display means when the time code correction process to be controlled and the display content of the display means are to be confirmed, the actual time counted by the real time counting means is displayed. Real time setting processing for controlling the time information to be set for the time code generating means.

According to the present invention, the predetermined information is displayed next to the predetermined numerical value in response to the numerical value feeding by the numerical value feeding operator as in the case of correcting the time code. Then, in a state where the predetermined information is displayed, for example, a predetermined confirmation operation is performed, or when the display content is automatically determined according to the elapse of the predetermined time, the predetermined time elapses, etc. The real time information is set to the time code generating means in response to the display content being determined.
In other words, this allows the user to set real-time information measured by the real-time timing unit in the time code generation unit by using the same operator as that used when correcting the time code. As a result, when setting real-time information in the time code generating means, it is not necessary to provide a separate operator for that purpose as in the prior art.

As described above, according to the present invention, it is possible to set real time information in the time code generation means, and there is no need to provide a separate operation element for the real time information.
As a result, the number of operating elements to be mounted can be reduced. For example, even when the mounting space for operating elements is relatively small, such as when the recording device is of a portable type, effective use of the operating element mounting space Can be achieved.

  Hereinafter, the best mode for carrying out the invention (hereinafter referred to as an embodiment) will be described.

The search dial 11a is used, for example, to change the reproduction speed of video data or to send numerical values of various display values.

  The DATA key 11b, the SET key 11c, and the HOLD key 11d are operators used to correct time information in the present embodiment, which will be described later.

FIG. 2 is a block diagram showing an internal configuration of the recording / reproducing apparatus 1 shown in FIG.
In FIG. 2, the internal configuration of the recording / reproducing apparatus 1 is shown by extracting only the portions that are mainly necessary for performing operations as embodiments described later, and the other portions are omitted. .
First, also in FIG. 1, the disc loading unit 12 shown in FIG. 1 is shown. The disc loading section 12 is loaded with the optical disc D shown in the figure.

Here, as the optical disc D to which the recording / reproducing apparatus 1 of the embodiment corresponds, for example, recording / reproducing is performed with a laser wavelength λ = 405 nm and NA (numerical aperture) = 0.65, and a phase change film is used as the recording film. The data can be rewritten.
The recording capacity is about 23 GB (gigabytes), which is a relatively large capacity, so that high-resolution images for business use can be handled.
Hereinafter, the description will be continued assuming that video data is mainly recorded on the optical disc D.

Recording / reproducing with respect to the optical disk D loaded in the disk loading unit 12 is performed by the recording / reproducing unit 6.
The recording / reproducing unit 6 includes, as a configuration for recording / reproducing data recorded on the optical disc D, an optical head, a spindle motor, a servo circuit, a decoder for obtaining reproduction data, and an encoder for generating recording data. And so on.
In particular, in the case of the present embodiment, the time code may be recorded on the optical disc D so as to be attached to each frame image in the video data. A decoder for reproducing such a time code is also provided.
Video data reproduced from the loaded optical disk D is supplied to the video signal processing unit 7.
The reproduced time code is supplied to a CPU (Central Processing Unit) 2 described later.

Data to be recorded on the loaded optical disc D is input from the video signal processing unit 7 to the recording / reproducing unit 6.
Further, a time code generated by a time code generator 13 to be described later is input to the recording / reproducing unit 6.
The recording / reproducing unit 6 generates recording data in a predetermined data format based on the input video data and time code by the above-described encoder, and records the recording data on the optical disc D. To be.
At this time, recording data is generated in accordance with the predetermined data format, so that the time code is recorded as metadata to be attached to each frame image in the video data. . That is, video data is recorded on the optical disc D so that a time code is attached to each frame image.

The video signal processing unit 7 receives video data reproduced from the optical disc D by the recording / reproducing unit 6 and can also input video data from a video input terminal Tvin shown in the figure.
The video signal processing unit 7 performs various video signal processing (image signal processing) on the input video data. For example, processing such as video level adjustment processing, chroma level adjustment processing, setup level adjustment processing, chroma phase (phase) adjustment processing, system phase adjustment processing, and sync phase adjustment processing can be performed.
The video signal processing unit 7 executes each signal processing described above based on a set value that is instructed independently from the CPU 2 described later for each processing.

The output of the video signal processing unit 7 is supplied to the video output terminal Tvout and branched to be supplied to the character generator 8 as well.
The character generator 8 is configured to be able to superimpose characters such as characters, numerical values, and icons generated on the input data from the video signal processing unit 7.
In particular, in the case of the present embodiment, display data based on a time code generated by a time code generator 13 described later or a time code reproduced from the optical disc D is generated.

The character generator 8 can superimpose character data so that an image based on the input data from the video signal processing unit 7 is displayed on the background and the character is superimposed on the image. Alternatively, the display data can be generated so that only the character is displayed. Furthermore, it is possible to output the character signal as it is without superimposing it on the output from the video signal processing unit 7.
The character generator 8 switches these actions based on an instruction from the CPU 2 to be described later.

Output data from the character generator 8 is supplied to the display driver 9.
The display driving unit 9 drives the display unit 10, which is a liquid crystal display, for example, based on input data from the character generator 8. As a result, image display based on the output from the character generator 8 is performed on the display unit 10.

The time code generator 13 generates a time code to be recorded on the optical disc D together with the video data. The time code generator 13 measures time in a predetermined time unit and generates a time code for every predetermined time.
This time code is information to be added for each frame image in the video data. For example, a time unit such as n hours m minutes l seconds k frames is provided in units of frames in the lower digits of the hour, minute and second. Is generated (generated).
In the case of the present embodiment, the NTSC (National Television System Commitee) system is adopted as the video data standard, and the time code generator 13 correspondingly measures time in a unit of 59.94 Hz frame period. Is configured to do. In other words, the frame digit value is counted one by one with a frame period of 59.94 Hz, and the time digit is incremented by one every time the frame digit value is counted 30 times. The

The time code generator 13 also generates a time code based on the real time in response to the real time information being set as will be described later.
Here, when the time code is generated by performing the time measurement with the frame period of 59.94 Hz as described above, there is a gradual deviation between the time code and the real time.
Therefore, as the time code generator 13, as an operation mode for eliminating such a discrepancy with the real time, a drop frame for measuring time by skipping a predetermined number of digits of the time code frame every predetermined period. It is configured to be able to operate as a (DropFrame) mode. For example, in this case, it is assumed that the time is measured twice every minute by skipping one numerical value of the frame.
The time code generator 13 performs such switching to the drop frame mode based on an instruction from the CPU 2 described later.

  The time code generated by the time code generator 13 is supplied to the recording / reproducing unit 6 as shown in the figure. The time code is branched and supplied to the character generator 8.

  The CPU 2 performs overall control and arithmetic processing of the recording / reproducing apparatus 1 based on the activated program. For example, an operation corresponding to an operation input from the operation unit 11 shown in the figure, a recording / reproducing operation for the optical disc D loaded in the disc loading unit 12, an access operation, and the like are controlled.

The CPU 2 includes a ROM (Read Only Memory) 3, a RAM (Random Access Memory) 4, and a flash memory 5 as shown in the figure.
The ROM 3 stores an operation program for the CPU 2, a program loader, and the like. In particular, in the case of the present embodiment, the ROM 3 also stores a program for causing the CPU 2 to execute processing operations (FIGS. 5 and 6) for realizing operations as embodiments to be described later.

The RAM 4 temporarily secures a data area and a task area for the CPU 2 to execute the program.
The flash memory 5 is a non-volatile memory that can rewrite data and retain recorded data even after the power is turned off. The flash memory 5 stores various calculation coefficients, parameters used in programs, and the like.

The operation unit 11 comprehensively shows the various operators (11a to 11d) shown in FIG. In the operation unit 11, operation information (operation signal) for each operator of the DATA key 11b, the SET key 11c, and the HOLD key 11d is supplied to the CPU 2. For the search dial 11a, operation information indicating the rotational movement position is supplied to the CPU 2 from an internal rotary encoder (not shown) in accordance with the rotation operation.
The CPU 2 executes a processing operation according to the operation information from the operation unit 11, thereby realizing an operation according to a user instruction.

Further, a real time timer 14 is provided for the CPU 2. The real time timer 14 measures real time (current time). For example, in this case, real-time information based on hour, minute, and second is generated and supplied to the CPU 2.

-Time code correction-

Here, the recording / reproducing apparatus 1 of the embodiment is configured to be able to correct the time code generated by the time code generator 13 in accordance with a user operation.
Hereinafter, with reference to FIG. 3, an operation to be performed by the user for correcting the time code and a screen transition on the display unit 10 according to the operation will be described.

First, in a predetermined area on the display unit 10, time information as shown in FIG. 3A is displayed in a normal display as an initial state.
As shown in the figure, time information displayed for a predetermined area on the display unit 10 includes frame digits (number of frames) by “F” and “10F” in order from the lower digit side to indicate the value of the time code. 1's digit, 10's digit), "S" and "10S" Sec digits (seconds digit, tens digits), "M""10M" Min digits (fractional digits, ten digits) ), “H”, “10H”, Hour digits (first digit and tenth digit) are secured.
Here, as an example, as time information, it is assumed that “12”, “34”, “56”, and “00” are displayed in order from the Hour digit as illustrated.
For confirmation, such time information is based on the time code generated by the time code generator 13 or the time code reproduced from the optical disc D by the character generator 8 shown in FIG. Are displayed on the basis of the display data generated.

In the initial state shown in FIG. 3A, the user can switch to the time information correction mode by operating the HOLD key 11d shown in FIG.
When switching to such a correction mode is performed, a display portion of a predetermined digit of time information is displayed blinking. That is, as shown by the broken line in FIG. 3B, in this case, the display portion of the Hour digit is displayed blinking.
In the initial state shown in FIG. 3A, such blinking display is not performed. In that sense, the display mode of the time information in the initial state shown in FIG. 3A is called “normal display” as described above.

Such blinking display serves to notify the user that the mode has been switched to the correction mode, and also represents the position of the digit to be corrected.
In this case, when the position of the blinking digit is changed, the search dial 11a is operated as shown in the transition from FIG. 3 (b) to FIG. 3 (c). For example, when an operation of turning the search dial 11a to the right as shown in the figure is performed, the blinking display that was the Hour digit in FIG. 3B is changed to the Min digit.
Although illustration is omitted, by further turning the search dial 11a clockwise, the blinking display sequentially moves to the Sec digit and the Frame digit. Thus, by rotating the search dial 11a in the right direction, the user can move the blinking display digit (correction target digit) to the lower digit.
Note that the blinking digit can be moved to the upper digit in response to the operation of turning the search dial 11a counterclockwise.

Further, when the numerical value of the blinking digit is corrected, for example, as the transition from FIG. 3 (b) to FIG. 3 (d) or the transition from FIG. 3 (c) to FIG. 3 (e). As shown, the search dial 11a is turned while pressing the DATA key 11b.
For example, when the search dial 11a is turned to the right while pressing the DATA key 11b in the state of FIG. 3B, the Hour digit value blinking as shown in FIG. 3D is incremented. Is displayed.
For example, if the search dial 11a is turned to the right while pressing the DATA key 11b in the state of FIG. 3C, the numerical value of the blinking Min digit is incremented as shown in FIG. Displayed.

  Although not shown in the figure, when the user turns the search dial 11a counterclockwise while holding down the DATA key 11b, the numerical value of the blinking digit is decremented and displayed.

In this case, when the numerical value is gradually incremented and displayed by turning the search dial 11a to the right while pressing the DATA key 11b, the Min digit value and the Sec digit value are next to “59”. “00” is displayed, and the numerical value of the Frame digit is “29” followed by “00”.
Further, when the numerical value is gradually decremented and displayed by turning the search dial 11a to the left while pressing the DATA key 11b, the Min digit value and the Sec digit value are "59" and "59". Is displayed, and the numerical value of the Frame digit is “00” followed by “29”.
For the Hour digit, predetermined information is inserted between “23” and “00”, which will be described later.

  In this way, after the user presses the HOLD key 11d to switch to the correction mode, the user operates the search dial 11a to change the blinking digit, or while holding down the DATA key 11b, the search dial 11a. The time code value to be corrected can be input by changing the numerical value of the blinking digit by performing an operation of turning.

Note that the user can cancel the correction mode and return the time information to the original normal display state by operating the HOLD key 11d again after switching to the correction mode. That is, it is possible to return to the normal display that is not blinked.
At this time, for example, as shown in FIG. 3D, the displayed numerical value is changed from the original numerical value (in this case, the original numerical value “12” of the Hour digit is changed to “13”). When the operation with the HOLD key 11d is performed, the changed numerical value is not reflected and the original numerical value before the correction mode (in this case, “12: 34: 56: 00”) is displayed. The

On the other hand, in this case, when the value of the time code is corrected to the input numerical value, the SET key 11c is operated.
Then, the currently displayed numerical value is set for the time code generator 13. And as time information, it returns to a normal display.
For example, when the SET key 11c is operated in the state shown in FIG. 3D, time information of “13: 34: 56: 00” is set in the time code generator 13, whereby the value of the time code is changed to “ 13: 34: 56: 00 ".

-Operation as an embodiment-

Here, as described above, the recording / reproducing apparatus 1 according to the embodiment includes the real time timer 14 for measuring the real time. The recording / reproducing apparatus 1 according to the embodiment is configured such that the real time information timed by the real time timer 14 can be set in the time code generator 13. That is, when recording the time code based on the real time on the optical disc D together with the video data, the time information of the time code generator 13 is adjusted to the real time by performing a manual correction operation as described above, for example. It is made to be able to omit such troubles.

FIG. 4 shows a user operation to be performed in order to cause the recording / reproducing apparatus 1 to set the time code generator 13 with the real time information timed by the real time timer 14, and the display unit 10 corresponding to the operation. The transition of the content of the time information above is schematically shown.
First, when the user is to cause the time code generator 13 to set real-time information by the real-time timer 14, the user switches to the correction mode. Switching to the correction mode is performed by operating the HOLD key 11d when the display of the time information on the display unit 10 is a normal display as described above with reference to FIG.
Also in this case, the switching to the correction mode is performed in a state where the time information of “12: 34: 56: 00” is displayed as the normal display, and the time information on the display unit 10 is illustrated in FIG. Assume that the same contents as in FIG. 3B are displayed as shown in FIG.

Here, after switching to the correction mode as described above, if the operation of turning the search dial 11a to the right until the flashing numerical value becomes 23 while pressing the DATA key 11b as shown in the figure, As information, as shown in FIG. 4B, the value of the Hour digit is “23”.
Then, if the user further turns the search dial 11a clockwise while holding down the DATA key 11b, as shown in FIG. 4C, “CLOCK” is displayed in the time information display area. Will be done.
If the search dial 11a is further turned to the right while pressing the DATA key 11b, the display content of the time information display area is returned to the time information as shown in FIG. The numerical value of the digit is set to “00”.

  Although not shown in the figure, when the user turns the search dial 11a counterclockwise while holding down the DATA key 11b, the value of the Hour digit is gradually decremented. At the time of reverse feeding of such numerical values, “CLOCK” is similarly displayed after “00”. If a reverse operation is further performed by turning the DATA key 11b + search dial 11a counterclockwise while this “CLOCK” is displayed, the display content of the time information display area returns to the time information, and the value of the Hour digit is “23. It is made to become.

  In the present embodiment, as shown in FIG. 4C, the operation of the SET key 11c in the state where “CLOCK” is displayed on the display unit 10 (the operation of determining the input value in the correction mode). ) Is assigned as an operation for setting the real time information to the time code generator 13.

That is, when the operation by the SET key 11c is performed in the display state of “CLOCK” shown in FIG. 4C, the real time information generated by the real time timer 14 is set in the time code generator 13. To be.
As a result, when the time code is recorded on the optical disc D thereafter, the time code based on the real time is sequentially supplied to the recording / reproducing unit 6. Thereby, the time code based on the real time can be recorded on the optical disc D together with the video data.

Here, in the present embodiment, when setting the real time information generated by the real time timer 14 in the time code generator 13 in this way, the operation mode of the time code generator 13 is further set to the drop frame mode. A switching operation is performed.
By switching to the drop frame mode, the error between the time code generated by the time code generator 13 and the real time can be prevented from being enlarged, and the synchronization between the time code and the real time can be prevented. A state can be ensured.

Although not shown, the display on the display unit 10 after the setting to the real time information in the time code generator 13 and the switching to the drop frame mode is returned to the normal display. To be done. That is, the display state before switching to the correction mode is restored.

-Processing operation-

The flowcharts of FIGS. 5 and 6 show processing operations to be performed in order to realize the time code correction operation described above and the operation according to the present embodiment.
The processing operations shown in FIGS. 5 and 6 are executed by the CPU 2 shown in FIG. 2 based on a program stored in the ROM 3. In FIG. 5, it is assumed that the time information is normally displayed on the display unit 10 (see FIG. 3A).

  First, in FIG. 5, in step S101, a HOLD key operation is waited. If an operation input by the HOLD key 11d is obtained and the HOLD key is operated, the Hour digit blinking display process is performed in step S102. That is, the character generator 13 is instructed so that the hour digit value in the time information displayed on the display unit 10 is blinked.

  Depending on step S103, step S104, step S105, and step S106, a loop is formed that waits for any of the search dial operation, DATA key operation + search dial operation, SET key operation, and HOLD key operation to be performed.

In step S103, if an operation input accompanying the operation of the search dial 11a is obtained and an affirmative result is obtained, the process proceeds to step S107, and processing for moving the blinking display to the next digit is performed. In this case, if it is determined from the operation information from the rotary encoder that the rotation direction of the search dial 11a is rightward, an instruction is given to the character generator 8 so that the blinking display is moved to the lower digit. Is done. When the rotation direction is the left direction, an instruction is given to the character generator 8 so that the blinking display is moved to the upper digit. When the process of step S107 is executed, the process returns to step S103. .

If an affirmative result is obtained in step S106 that an operation input by the HOLD key 11d has been obtained and the HOLD key has been operated, the process proceeds to step S108 as shown and processing for returning to the normal display is performed. To be executed. That is, an instruction is given to the character generator 8 so that the original numerical value displayed as the time information at the time of step S101 is displayed by the normal display without the blinking display.
Thus, when the HOLD key operation is performed once (Step S101) and the HOLD key operation is performed again after switching to the correction mode, the time information on the display unit 10 is as described above. Even if the numerical value is changed, the changed numerical value is not reflected, and the original numerical value is normally displayed without blinking.

  In step S104, if the operation input by the DATA key 11b and the operation input associated with the operation of the search dial 11a are obtained, and a positive result is obtained that there is a DATA key operation + search dial operation, The process proceeds to the process shown in FIG.

  In FIG. 6, first, in step S201, step S202, step S203, and step S204, a determination process is performed to determine whether the blinking digit is a Hour digit, a Min digit, a Sec digit, or a Frame digit.

If an affirmative result is obtained in step S201 that the blinking digit is the Hour digit, the process proceeds to step S205 to determine the rotation direction of the search dial.
In step S205, if it is determined from the operation information from the rotary encoder that the rotation direction of the search dial 11a is rightward, the process proceeds to step S206. If the current value is 23, CLOCK is displayed. Is set to 00, otherwise, a process for adding one to the current value is performed.
That is, if the numerical value displayed in the Hour digit of the time information on the current display unit 10 is “23”, the character generator 8 is displayed so that the information “CLOCK” is displayed in the time information display area. Give instructions.
Further, when “CLOCK” information is displayed in the time information display area on the current display unit 10, the information of “CLOCK” is displayed with numerical values of the Min digit, the Sec digit, and the Frame digit. The character generator 8 is instructed to return to the previous display state and display “00” in the Hour digit.
In addition, when the numerical value displayed in the Hour digit of the time information on the current display unit 10 is not “00” and “23” and the information of “CLOCK” is not displayed, the numerical value of the Hour digit is displayed. The character generator 8 is instructed to display a value obtained by incrementing the currently displayed value by one.

When the process of step S205 is executed, the process returns to step S103 in FIG. 5 as shown in the figure, whereby the search dial operation, DATA key operation + search dial operation, SET key operation, HOLD key are performed again. It waits for any of the operations to be performed.
As shown in the figure, steps S207, S209, S210, S212, S213, S215, and S216 described below are similarly returned to step S103 after the processing is executed.

If it is determined in step S205 that the rotation direction of the search dial 11a is the left direction, the process proceeds to step S207. If the current value is 00, CLOCK is displayed. If the current value is CLOCK, the value is 23. Otherwise, a process for subtracting 1 from the current value is performed.
That is, if the numerical value displayed in the Hour digit of the time information on the current display unit 10 is “00”, the character generator 8 is displayed so that the information “CLOCK” is displayed in the time information display area. Give instructions.
Further, when “CLOCK” information is displayed in the time information display area on the current display unit 10, the information of “CLOCK” is displayed with numerical values of the Min digit, the Sec digit, and the Frame digit. The character generator 8 is instructed to return to the previous display state and display “23” in the Hour digit.
Further, when the numerical value displayed in the hour digit of the current time information on the display unit 10 is not “23” or “00” and the information of “CLOCK” is not displayed, the numerical value of the hour digit is displayed.

Returning to FIG.
In FIG. 5, in step S105 described above, in step S105, if there is an operation input from the SET key 11c and the SET key operation is performed, a positive result is obtained. As shown in the figure, the process proceeds to step S109.

  In step S109, it is determined whether or not the current CLOCK display is in progress. That is, by the processing of step S206 or S207 in FIG. 6, the determination processing is performed as to whether or not the information of “CLOCK” is displayed in the time information display area on the display unit 10.

If a negative result is obtained in step S109 that the CLOCK display has not been performed, the process proceeds to step S110, and a process of setting the time currently being displayed in the time code generator is executed. That is, time information based on the numerical value currently displayed in the time information display area on the display unit 10 is set for the time code generator 13.
Thus, the time code generated by the time code generator 13 can be corrected (updated) based on the user input value.

In subsequent step S111, processing for returning to the normal display is executed. That is, an instruction is given to the character generator 8 so that normal display without blinking display is performed as time information.
In this case, since the time code is corrected in accordance with the SET key operation, the numerical value of the time information is maintained as it is without returning to the original numerical value.

On the other hand, if a positive result is obtained in step S109 that the CLOCK display is being performed, the process proceeds to step S112 to set the real time in the time code generator and perform processing for switching to the drop frame mode. To be executed.
In other words, the real time information generated by the real time timer 14 is set in the time code generator 13 and the time code generator 13 is instructed so that the operation mode can be switched to the drop frame mode.

In the subsequent step S113, processing for returning to the normal display is executed. That is, as in the previous step S108, the character generator 8 is instructed to return to the display state before switching to the correction mode.

-Summary of embodiment and modification-

As described above, in the present embodiment, in the time code correction mode, the real time information by the real time timer 14 is set in the time code generator 13 after a predetermined value of the Hour digit. “CLOCK” information (predetermined information) is displayed, and the above SET C key operation is performed in the display state of this “CLOCK” information in response to the same SET key operation as the operation for determining the correction value. Time information is set in the time code generator 13.

  In this way, in the present embodiment, the operation to be performed when setting the real time information by the real time timer 14 in the time code generator 13 is at least the HOLD key operation for switching to the correction mode. , DATA key operation for numeric feed + search dial operation, SET key operation for confirming display contents, and operation to be performed for time code correction can be made common.

  As a result, when the real time information by the real time timer 14 is set in the time code generator 13, it is not necessary to provide a separate operator as in the prior art. According to this, the number of operators to be mounted can be reduced. For example, when a portable type is used like the recording / reproducing apparatus 1 of the present embodiment, the space for mounting the operators is relatively small. Even in this case, it is possible to effectively use the mounting space for the operation element.

Here, the present invention should not be limited to the embodiments described so far.
For example, the names of the controls are not limited to those exemplified in the embodiment.
In addition, although the case where a dial operator using a rotary encoder is illustrated as an operator for feeding a numerical value, for example, two operators, that is, an operator that forwards numerical values and an operator that feeds backwards are numerical feed operations. The present invention can also be suitably applied to a case where an operator other than the dial operator is a numerical value feed operator such as a child.

In the embodiment, the operation of the search dial 11a alone is assigned to the instruction to change the correction target digit, and the operation of the search dial 11a while the DATA key 11b is pressed changes the value of the target digit (send). ) Although the case where the instruction is assigned is illustrated, the relationship between the operation content and the instruction can be reversed.
However, in any case, the CPU 2 is still controlled to send the displayed numerical value based on the operation of the search dial 11a (in this case, the numerical value feed operator).

  Further, in the embodiment, the case where the display value is confirmed as the time code correction value or the real time information is set in the time code generator 13 in accordance with the operation of a predetermined confirming operator as the SET key 11c is exemplified. However, instead of this, for example, it is determined that the display content should be determined by the CPU 2 when the no-operation state continues for a predetermined time or more, and the display value is determined as the correction value of the time code, or The real time information may be set in the time code generator 13.

  In the embodiment, the case where the real time information (and time code) is set to hours: minutes: seconds (: frames) is exemplified. However, for example, time information further including year / month / day may be used. it can.

  In the embodiment, the information “CLOCK” is displayed as the predetermined information indicating that the real-time information by the real-time clock unit 14 is set in the time code generator 13. Can also be other information.

In the embodiment, the predetermined information is displayed in place of the time information. However, the predetermined information may be displayed while the time information is displayed.
The predetermined information is displayed in response to a feed operation from the display state of a predetermined value in the Hour digit, but the predetermined information is in response to a feed operation in a display state of another predetermined value in another digit. It can also be displayed. For example, in the case of a Min digit, the predetermined information is displayed in response to the forward movement in the display state of “59” or the backward movement in the display state of “00”.

In the embodiments, the case where the recording apparatus of the present invention is applied to an apparatus for recording and reproducing an optical disk recording medium is exemplified. However, a configuration corresponding to a recording medium other than the optical disk recording medium may be used. it can.
In the embodiment, the case where the recording apparatus of the present invention is a portable editing apparatus for business use is exemplified. However, the present invention records video data and a time code on a recording medium such as a video camera apparatus. The present invention can be widely applied to apparatuses configured to do so.
