Abstract

PROBLEM TO BE SOLVED: To switch scenes with an effect corresponding to at least either the time or position of a scene. SOLUTION: When recording is started in a step S1, the existence/absence of the preceding scene is discriminated. When the preceding scene does not exist, in a step S6, a scene is recorded without adding effects. In a step S9, processing is finished at all times, when recording is performed. When the preceding scene exists in a step S1, time in the preceding scene becomes progressive motion at all times in a step S2. So, in a step S3, whether a photographing position is the same as that of the preceding scene is decided. When positions are different, in a step S7, a wipe is inserted and the processing is finished. When the positions are the same, in a step 4, whether the time difference from the preceding scene is equal to or more than 10 minutes is decided. When it is >=10 minutes, in a step S8, fade-in/fade-out are inserted, and the processing is finished. When it is <10 minutes, in a step 5, a mix is inserted and the processing is finished.

In step S9, the microcontroller 48 determines whether there is a next scene. At the time of recording, the scene ends at the same time as the end of recording, so that the processing ends. That is, in the process of step S9 during recording, it is always determined that there is no next scene,
The process ends. The processing at the time of reproduction will be described later.

When recording scene 2, step S1
In, since the scene 1 exists, the microcontroller 48 determines that the previous scene exists, and proceeds to the process of step S2.

In step S2, the microcontroller 48 determines whether or not the previous scene and the absolute time are forward. In this example, the time of scene 1 is 1
Since the time of scene 2 is from 13:10 to 13:13 on June 10, 1999, the time of scene 2 is from 13:20 to 13:30 on June 10, 1999, the scene 1 and the scene 1 It is determined that the absolute time of 2 is going forward, and the process proceeds to step S3.

Note that the processing in step S2 is necessary in the case of continuous reproduction of scenes during reproduction, and in recording, the time is always forward. Therefore, in step S2, the time is always relative to the absolute time. And the process proceeds to step S3.

In step S3, the microcontroller 48 determines whether the positions of scene 1 and scene 2 are the same. In this example, the position of scene 1 is east longitude 135
45 minutes, 140 degrees 20 minutes north latitude, and scene 2
Is also 135 ° 45 minutes east longitude and 140 ° 20 minutes north latitude, it is determined that they are the same position, and the process proceeds to step S4.

In step S4, the microcontroller 48 determines whether or not the difference between the absolute time and the previous scene is 10 minutes or more. In this example, scene 1
Is different from the recording start time of scene 2
Since it is seven minutes, it is determined that the difference between the absolute times is not more than ten minutes, and the process proceeds to step S5.

In step S5, the microcontroller 48 instructs the system controller 42 to switch from scene 1 to scene 2 using the special effects of the mix. The system control unit 42 generates a script that switches the end image of the scene 1 while overlapping the start image of the scene 2 based on the processing procedure of the mix stored in the memory 41 in advance.
Is recorded on the disk 72 in response to the request, and the process is terminated.

When recording scene 3, in step S1, it is determined that there is a previous scene, and in step S2, it is determined that the time is forward. Then, in step S3, it is determined whether or not the positions are the same. Since the positions are the same, the process proceeds to step S4.

In step S4, the microcontroller 48 determines whether or not the difference between the absolute times of the previous scene and the previous scene is 10 minutes or more. In this example, the difference between the absolute times of the scene 2 and the scene 3 is Since the time is 24 minutes, it is determined that the time is 10 minutes or more. In step S8, the microcontroller 48 controls the system control unit 42 to add a special effect of fade-out / fade-in to the scene 2
, A script for switching to scene 3 is generated and recorded on the disk 72.

When recording scene 4, step S1,
After the processing in step S2, in step S3, the microcontroller 48 determines whether the positions of scene 3 and scene 4 are the same. In this example, the position of scene 3 is 135 degrees 45 minutes east longitude and 140 degrees 20 minutes north latitude, while the position of scene 4 is 130 degrees 33 minutes east longitude and 145 degrees 15 north latitude. Is not determined, and the process proceeds to step S7.

In step S7, the microcontroller 48 instructs the system controller 42 to switch from scene 3 to scene 4 using the special effect of the wipe. The system control unit 42 generates a script for switching the image of the scene 3 to the image of the scene 4 based on the wipe processing procedure stored in the memory 41 in advance, and records the script on the disk 72.

The operation for recording scene 5 is the same as the operation for recording scene 3, and a description thereof will be omitted.

Next, as described above, the disk 72
Next, the operation of the digital video camera when the image data of scenes 1 to 5 as shown in FIG. 4 is recorded and reproduced according to the script generated at the time of recording will be described.

When the reproduction start command is issued, the microcontroller 48 sends the disc 72 via the system control unit 42, the media drive unit 15, and the mechanical deck unit 16.
Reads the script file recorded in, and executes the reproduction process according to the script. As mentioned above,
The script describes the playback order of the scenes and the effects at the time of scene switching, and the first scene specified in the script (scene 1 in this case) is played back correspondingly.

Since there is no previous scene, the switching of the scene 1 is not performed, and the scene of the scene 1 recorded on the disk 72 by the microcontroller 48 via the system control unit 42, the media drive unit 15, and the mechanical deck unit 16 is not performed. A command to read image data is issued. Then, a predetermined track of the rotating disk 72 is irradiated with a laser beam by the optical pickup unit 73 moved to a predetermined radial position of the disk 72 by the sled motor 74, and a signal is read from the light reflected by the disk 72.

The read signal is amplified by the RF amplifier 63 and converted from an analog signal to a digital signal by the RF ADC 64. The image data converted into the digital signal is subjected to gain control in the AGC unit 99 and is subjected to equalization processing by the equalizer 100. The equalized image data is subjected to Viterbi decoding by a Vidavi decoder 101, demodulated by an RLL (1,7) demodulator 102, and then stored in a memory 61. The image data stored in the memory 61 is subjected to error correction processing in the ECC unit 92, and is further descrambled in the descrambler 93. The signal is EDC decoded and output to the video signal processing unit 14 in synchronization with the clock signal generated from the transfer clock generation unit 94.

The image data of the signal input to the video signal processing section 14 is transmitted to the MPEG
The video processor 44 performs MPEG decoding processing and outputs the result to the interface unit 17. The audio signal is subjected to ATRAC decompression processing in the ATRAC processing unit 47, converted into an analog audio signal by the DAC 85 of the interface unit 17, and output from the line output terminal 21.

The image data output from the video signal processing section 14 is converted from a digital signal into an analog signal by the video DAC 81 and output to the LCD 18 via the LCD controller 82 for display.

After the reproduction of the scene 1 is completed, a special effect of the mix is added to the switching to the next scene, the scene 2, according to the script generated at the time of recording. At this time, the system control unit 42 generates an image to be switched while overlapping the start image of the scene 2 with the end image of the scene 1 based on the processing procedure of the mix stored in the memory 41 in advance. The image is displayed on the LCD 18 via the.

The switching from the reproduction of the scene 2 to the next scene, the scene 3, also has a fade-out / fade-in special effect according to the script. That is, a single-color image is overlapped with the end image of the scene 2, and a start image of the scene 3 is overlapped and displayed on the single-color image.

When the reproduction of scene 3 is completed, the image of scene 4 is displayed with a special wipe effect added according to the script.

When the reproduction of scene 4 is completed, scene 5 is displayed with a special effect of fade-out / fade-in added according to the script. When the reproduction of the scene 5 ends, the reproduction ends because the next scene does not exist in the script.

When the image data of scenes 1 to 5 as shown in FIG.
Each scene can be reproduced in a predetermined order with a predetermined effect. In this case, the user may input
And specify the order and effect of each scene by script editing. Thus, the edited script file is recorded on the disc 72. Thereafter, when an instruction to start reproduction is issued, a reproduction process is executed in accordance with the edited script.

The microcontroller 48 stores a default script on a scale 49. When the user operates the input device 24 to instruct reproduction according to the default script, the microcontroller 48 Playback is controlled according to this default script. This default script has the contents shown in the flowchart of FIG. However, at this time, the user specifies only the playback order of the scenes.

Now, when the order of the scenes 1, 2, 3, 5, 4 is specified and the reproduction start is instructed, the microcontroller 48 reads the script file stored in the memory 49 and responds accordingly. , The first scene (scene 1 in this case) is reproduced.

That is, in step S1, the microcontroller 48 determines whether there is a previous scene. In this example, since there is no scene before scene 1, it is determined that there is no previous scene, and step S
Proceed to step 6.

In step S6, the image data of scene 1 is reproduced without adding an effect, and is output to LCD 18 for display.

The process of reproducing scenes 1 to 3 is the same as the process according to the script generated at the time of recording. That is, reproduction of scene 1 is performed in step S
6, S9, and the reproduction of scene 2 is processed in the order of steps S2, S3, S4, S5, and S9, and the reproduction of scene 3 is processed in the order of steps S2, S3, S4, and S8.

When the reproduction of scene 3 is completed, step S
At 9, it is determined whether or not there is a next scene. In this example, since scene 5 is reproduced, the process returns to step S2.

In step S2, it is determined whether or not the absolute time is forward. In this example, the absolute time of scene 3 is from 13:54 to 14:00 on June 10, 1999.
While the time is 0 minutes, the absolute time of scene 5 is 1999
Since the time is from 9:50 to 9:55 on June 11, 2008, it is determined that the line is forward, and the process proceeds to step S3.

In step S3, the microcontroller 48 determines whether the shooting positions of the scene 3 and the scene 5 are the same. In this example, the shooting position of scene 3 is 135 degrees 45 minutes east longitude and 140 degrees 20 minutes north latitude, whereas the shooting position of scene 5 is 130 degrees 33 minutes east longitude and 1 latitude north
Since the angle is 45 degrees and 15 minutes, it is determined that the positions are not the same, and the process proceeds to step S7.

In step S7, the microcontroller 48 instructs the system controller 42 to switch from scene 3 to scene 5 by adding a special wipe effect. The system control unit 42 generates image data that is slid and pushed so as to push out the end image of the scene 3 with the start image of the scene 5 based on the wipe processing procedure stored in the memory 41 in advance, and the interface unit 17 And causes the LCD 18 to display the image data.

In step S9, since scene 4 is reproduced after scene 5, it is determined that there is a next scene.
It returns to the process of step S2. In step S2, it is determined whether or not the absolute time is forward. In this example, the absolute time of scene 5 is from 9:50 to 9:55 on June 11, 1999, Since the absolute time of scene 4 is from 9:31 to 9:42 on June 11, 1999, it is determined that the scene is not forward, and the process proceeds to step S7.

In step S7, the system control unit 4
2 generates image data for switching from scene 5 to scene 4 by adding a special wipe effect, and displays the image data. In step S9, it is determined whether or not there is a next scene. When the reproduction of the scene 4 ends, the processing ends because there is no next scene.

In the above, the case where the number of scenes is five has been described. However, any number of scenes recorded on the disk 72 may be used arbitrarily. Alternatively, a script may be created by recording image data using a plurality of digital video cameras, copying the image data for each scene after shooting, and collecting the image data on one disk.

Further, in the above description, there are four types of special effects for switching scenes: no effect, fade-out / fade-in, wipe, and mix, but more special effects for switching are used. Well,
Further, the special effect of switching in the processing of steps S5 to S8 in FIG. 5 may be changed by rewriting the script file, or the user may manually select a desired special effect of switching at the time of editing. good.
