Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a technique for recording information on a recording medium.

[0002]

2. Description of the Related Art Recently, DVDs (digital versatile media) have been used as media for video titles such as movies for home viewing.
tile disk) is becoming popular. The movie distribution company manufactures and distributes titles using DVD as a medium, as well as conventional home video tapes. General users can purchase a home DVD player and watch movies recorded on DVDs at home. this
DVD-R (DVD-Recordable), which is compatible with DVD, is a write-once optical disc that allows a user to record video and audio information owned by the user. Commercialization of home video cameras using DVD-R as a recording medium is expected. However, in order to be compatible and playable on the DVD player, it is necessary to perform a recording end process, that is, a finalize process on the DVD-R disc.

2 and 3 are views for explaining the finalizing process. The left end of the figure is the inner track and the right end is the outer track. (Note that the detailed structure of the data is also disclosed in Japanese Patent Laid-Open No. 8-273304.) Before finalizing, as shown in FIG. 2, the lead-in control data area already recorded at the time of manufacturing the DVD-R. (Lead-in / Control Data Zone) and user video
There is a user data area that records audio data. As a result of the finalizing process, as shown in FIG. 3, various management is performed between the lead-in control data area and the inner peripheral area up to the lead-in control data area, that is, the lead-in zone. A lead-out zone is recorded in the outer peripheral area of the information data and user data areas.

The lead-out area is defined as a track width of 2 mm or more (A in FIG. 3) for a disk having a diameter of 8 cm, but at a minimum position of 7 cm in diameter (B in FIG. 3). If the data to be recorded by the user is small, that is, if the width of the user data area is small, the lead-out area becomes large and it takes time to write the predetermined data to the lead-out area, so the time for the finalization process becomes long. .

A device using a DVD-R is, for example, Japanese Patent Laid-Open No. 8-273304.

[0006]

There is no consideration when mounting a DVD-R drive on a home video camera, and the user should be aware of the time required for the finalizing process after a short shooting time. If the finalizing process is performed without doing so, it takes a long time to perform the finalizing process, and during that time, shooting may not be possible, which may cause a problem of waiting.

The recording medium cannot be taken out during the finalizing process. Therefore, if the finalizing process takes time, replace it with a new recording medium,
You will have to wait until you start a new recording.

On the other hand, in the finalizing process, data is generally written in an unrecorded area. Therefore, the shorter the shooting time is, the larger the unrecorded area is, the more data is written to the area at the time of finalizing, and the longer the time is.

From the above, if the finalizing process is performed when the photographing time is short, the photographer must be replaced with a new recording medium and the recording must be started.

An object of the present invention is to solve the above problems and, for example, to reduce the waiting time due to the execution of finalizing processing so that recording and photographing can be started quickly on a new recording medium. Is to

And the estimation means,
The predetermined time is set within a range not exceeding the operable time estimated by the operation time estimating means.
Therefore, since the determination result is acceptable, the ending process is executed. Alternatively, when the amount of electric power that can be supplied from the battery to the information recording / reproducing device is detected and it is determined that the detected amount of electric power is equal to or larger than a predetermined amount of electric power, the ending process is performed. To be executed. On the contrary, when the detected power amount is smaller than the predetermined power amount, the ending process may not be executed.

In order to achieve the above object, in the information recording apparatus according to the present invention, a remaining capacity detecting means for detecting a data capacity left to be recorded on the recording medium is provided, and the processing time estimating means is the above. The time required for the termination processing is estimated based on the data capacity detected by the remaining capacity detecting means.

Further, in order to achieve the above object, in the information recording apparatus according to the present invention, when notifying means is provided and the ending processing is not performed, the notifying means notifies that the ending processing is not performed. To do so. Or, perform the condition judgment whether to execute the end process or not,

3, a set value area 52, a state value area 53, and a user set value area 54 are arranged therein. The set value area 52 stores various parameters that determine the operation of the system. It includes a system control information area and a drive information area, and the system information area includes finalize control information 55. The finalization control information 55 includes a set value (T0) of the time to allow finalization and information on whether to allow the finalization process in the currently used DVD-R. The state value area 53 stores current values regarding the states of the system, disk, drive, and camera. These values are managed by the program executed by the CPU 42 and are sequentially updated. The disc state value includes a finalize time 56, a disc capacity 57, and a recorded capacity 58.

The finalizing time T can be determined from the state of the disc (D) and the set value of the system (S). One of the calculation methods is the remaining recording capacity of the DVD-R, that is, the disc capacity (D1). A method of calculating from the value (D1-D2) obtained by subtracting the disc recorded capacity (D2) from the above and the processing performance (S1) of the DVD-R drive can be considered. The calculation method is shown below.

T = (D1-D2) / S1 + P1 (Equation 1) Equation 1 shows a calculation formula for this purpose. D1 is the disk capacity 57, D2 is the recorded capacity 58, and S1 is The finalization processing speed of the drive included in the drive information of the setting value area 52 is expressed in units of tracks, and the overhead (P1) of the processing time is taken into consideration.

FIG. 6 shows a flow chart of the finalizing control program executed by the CPU 42. This processing flow is executed when the user instructs the finalization processing. The processing block 61 calculates the finalization processing time T. In processing block 62, it is determined whether T exceeds a predetermined time (allowable time) T0, and the process is branched. If not exceeded (false), the control required for the finalization processing is performed in processing block 63. If so, processing block 64 displays a warning message to the user on display device 9 and waits for user confirmation. With the above processing, this processing flow ends.

In the above description, if the allowable time T0 for the finalizing process is exceeded, the finalizing process cannot be performed, but if the user is familiar with the handling of the finalizing process, the user input means 8 It is also possible to change a part of the user set value area 54 by an operation from to change the set value to 0 or the like to forcibly execute the finalizing process. For this purpose, a flag indicating whether the user is an advanced user and an area for setting the finalizing process are set in a part of the user setting value area 54, and the program executed by the system control means 6 manages the area.

FIG. 8 is a flowchart of the finalize control. In processing block 80, the remaining capacity R of the disk is calculated. The processing block 81 is the remaining capacity R of the disk.
Determines whether or not exceeds a predetermined capacity R0 that prohibits finalization processing, and performs branch processing. If R does not exceed R0, processing block 63 performs control to finalize. If R exceeds R0, processing block 82 displays a warning and waits for user confirmation. The finalization control is performed by the above processing.

The remaining capacity R can be calculated by the system control means sequentially managing the disk capacity D1 and the recorded capacity D2 as shown in the first embodiment.

It is also possible to implement a method of changing the set value R0 for a user who has sufficient operation knowledge, and to provide a setting for forcibly executing the finalizing process. For this purpose, the set value of R0 can be changed by the user input means, and this change can be incorporated into the management of the system control means.

Next, another embodiment of the present invention will be described. FIG. 9 shows an information recording / reproducing apparatus 90 for recording and reproducing information.
0 shows a schematic block diagram of 0. The signal detected by the optical pickup 918 is sent to the servo signal generation circuit 919 and the information signal reproduction circuit 920 in the signal processing circuit. In the servo signal generation circuit 919, a focusing control signal and a tracking control signal suitable for the optical disc are generated from these detection signals, and based on this, the objective lens actuator in the optical pickup 918 is driven via the actuator drive circuit 921, and the objective lens actuator is driven. Controls the position of the lens.
The information signal reproducing circuit 920 reproduces the information signal recorded on the optical disc 908 from the detection signal, and outputs the information signal to the information signal output terminal 928. A part of the signals obtained by the servo signal generation circuit 919 and the information signal reproduction circuit 920 is sent to the system control circuit 922.

Further, a camera signal processing circuit 929 (the optical system is not shown in FIG. 9, but an optical system may be included).
At, the recording information optically captured and converted into an electric signal is input to the recording information signal conversion circuit 924. The recording information signal conversion circuit 924 converts it into a predetermined laser driving recording signal. The laser driving recording signal is sent to the system control circuit 922, the laser light source lighting circuit 923 is driven to control the light emission amount, and the recording signal is recorded on the optical disc 908 via the optical pickup 918. An access control circuit 925 and a spindle motor drive circuit 926 are connected to the system control circuit 922, and the access direction position control of the optical pickup 918 and the rotation control of the spindle motor 927 of the optical disc 908 are performed respectively.

The finalizing process is performed by the system control circuit 9
Under the control of No. 22, the laser light source lighting circuit 923 and the optical pip-up 918 are applied to the optical disk 908.

In the embodiment shown in FIG. 9, the system control circuit 922 determines whether to execute the finalizing process. Note that the user controls the information recording / reproducing apparatus 900 by instructing the user input processing circuit 951 by the user. At this time, the display of the processing state of the information recording / reproducing apparatus may be performed by the display processing circuit 952. Especially the camera signal processing circuit 9
In the information recording / reproducing apparatus for recording the record information obtained from 29, by providing the display processing circuit 952 with a liquid crystal screen such as an LCD, it is possible to display and monitor.

Note that the recording information or the signal from the information signal reproducing circuit 920 is received, and the information recorded on the optical disk or the information reproduced from the optical disk is displayed and monitored by the display processing circuit 952. May be.

The information recording / reproducing apparatus 900 shown in FIG. 9 is supplied with electric power from the connected battery 950, and can be used as a portable type. Where the battery 95
Instead of connecting 0, a power supply circuit to which electric power is supplied from a commercial AC power supply is provided inside the information recording / reproducing device 900, so that it can be used as a stationary device. Also,
In the above, the recording signal from the camera signal processing circuit 929 is recorded, but another signal source may be provided and the output signal may be recorded as the recording signal. Alternatively, a recording signal input terminal may be provided and a signal input from the outside may be recorded as a recording signal.

Next, FIGS. 10 to 12 will be described with reference to examples of messages, warning screens and the like to be notified to the user at the time of executing the process in the above example.

FIGS. 10 and 12 explain the display contents in the processing step 64 of FIG. 6 of the first embodiment. That is, since the finalization process takes a long time, if the finalization process is performed unconditionally, the user will be kept waiting while the finalization process is performed. Further, when power is supplied from the battery, if the power cannot be supplied from the battery during the finalizing process, the finalizing process may fail, and in some cases, the optical disc may not be reproduced. Therefore, FIG. 10 and FIG. 12 show an example of a message confirming whether the finalizing process is to be executed, along with a warning that the finalizing process will take a long time. Further, FIG. 11 shows the processing step 82 of FIG. 8 of the second embodiment.
The contents displayed in the above are explained. That is, an example of a message for confirming whether or not the finalizing process is to be executed is shown together with a warning that the amount of unrecorded data is large. Therefore, similar to the message of FIG. 10, by performing the finalizing process on an unrecorded area having a large data capacity, it is possible to avoid making the user wait. Furthermore, if the finalizing process is performed, information cannot be additionally recorded on the optical disc, so if the finalizing process is performed due to an erroneous operation,
The optical disk cannot be used for recording. Therefore, when the message shown in FIG. 11 is issued as a warning, it is possible to avoid activation of the finalizing process due to an erroneous operation or the like.

Note that FIGS. 10 to 12 are examples, and the present invention is not limited to this, and the contents of the message, the design, and the display method are notified to the user of the process selection regarding the execution of the finalize process. As described above, it may be appropriately changed. Therefore, in addition to the warning as shown in Figures 10 to 12, a message such as "Do you want to force the finalization process?" YES "/" NO "" is displayed to inquire the user to start the finalization process forcibly. Then
If “YES” is selected, the finalizing process may be forcedly executed. In that case, "YE
When S ”is selected, the setting may be changed so that the condition determination can be forcibly executed, or the process may be jumped to the processing block 63 to forcibly execute the finalizing process.

In the embodiments of the present invention, the DVD-R has been mainly described as the optical disc, but the present invention is not limited to this, and it is possible to record at a higher density than a CD or a DVD. This embodiment can of course be applied to a recording medium.

In this embodiment, the video camera automatically determines whether or not the finalizing process is possible according to the remaining recording capacity of the disc, and the user mistakenly executes the finalizing process, and the next shooting is kept waiting for a long time. Can be prevented.

The predetermined time can be determined based on the amount of electric power that can be supplied from the battery to the information recording device.

However, it is not only based on the above-mentioned electric power amount, but is determined by statistically examining a value of time that humans perceive as a waiting time, for example, from a plurality of subjects. It may be.

In the above embodiment, the time based on the amount of electric power and the unrecorded capacity of the recording medium is compared with the value of the predetermined time to determine whether to execute the end process or not. I was supposed to However, instead of comparing the time values, the power consumption, the unrecorded capacity of the recording medium, and the like are compared with predetermined values, and the termination process is executed or not executed. The condition may be judged. For example, if time is obtained from the amount of electric power supplied from the battery and compared with a predetermined time, and if the time obtained from the amount of electric power supplied from the battery is greater than the predetermined time, the end The process is executed. However, instead of calculating the time from the amount of power supplied from the battery, if the amount of power supplied from the battery is larger than the predetermined amount of power, the termination process may be executed. In this case, even if the termination process is executed, the electric power required to execute the termination process is supplied from the battery, and the termination process does not fail due to insufficient power supply from the battery. .

The control of each processing unit and means of the above-described embodiment or the condition judgment is performed by the system control circuit.
To be executed. However, a processing circuit for controlling each processing unit or means of the above-described embodiment or for performing condition determination may be provided separately from the system control circuit.

According to the above-described embodiment, the video camera can automatically recognize the recorded state and judge whether or not the finalizing process can be performed. Therefore, for example, the user performs the finalizing process by an erroneous operation and shoots for a long time. You can avoid waiting. Therefore, for example, it becomes possible to reduce the waiting time due to the execution of the finalizing process as compared with the conventional one, and it is possible to promptly start recording on a new recording medium and start photographing.
