[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording apparatus, and more particularly to a recording apparatus capable of recording an audio signal edited in association with an image signal.
[0002]
[Prior art]
CD-G (Compact Disc-Graphics), one of the compact disc-related, records graphics (color still images) in an empty channel of an audio CD, records it, connects it to a home TV, and uses only audio signals. And still images can be played back. In addition, a system capable of recording and reproducing audio, video, and data such as CD-I (Compact Disc-Interactive Media) has been put into practical use. Naturally, magneto-optical disks that can be erased and re-recorded in conformity with these standards are also considered. Further, a configuration in which an audio signal is recorded simultaneously with image recording is also considered in a digital camera or the like. In addition to this, there are many cases where it is desired to perform recording processing by associating an image recorded with a recorded sound, such as a video tape recorder, although it is not a still image.
[0003]
Thus, when recording an image signal and an audio signal, in the conventional example, the audio before and after the image signal capture cannot be arbitrarily edited and recorded on the user side. Normally, audio signals are usually recorded automatically in conjunction with image signal capture. For this reason, if you try to record the actual sound at the time of imaging as it is, unnecessary audio signals before and after will be recorded, or the correspondence between the required audio signal and image signal can not be taken, and there is a time difference There was a problem like that.
[0004]
In order to avoid this problem, it is necessary to edit audio freely. However, when editing audio and images in association with each other, conventionally, a plurality of playback devices, recording devices, studios for editing, etc. are required, and there is still no simple device for editing and storing audio in association with images. Not put into practical use.
[0005]
[Problems to be solved by the invention]
As described above, in the conventional simultaneous recording apparatus for image signals and sound, the correspondence between the necessary sound signals and the image signals cannot be obtained, so that unnecessary sound signals are reproduced or the sound is shifted in time. There is a problem that the signal is reproduced, which is inconvenient and unnatural for the user.
[0006]
The present invention solves this problem and allows the user to arbitrarily edit audio signals recorded before and after the image signal, and record the edited audio signal in association with the image signal in a simple manner. It is an object to provide an apparatus.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a recording apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
1 and 2 are block diagrams showing the configuration of the recording apparatus according to the embodiment of the present invention.
1 and 2, 1 is a CPU, 2 is an operation unit, 3 is a memory, 4 is a storage memory, 5 is a CCD (camera) unit, 6 is an image format generation unit, 7 is a microphone unit, and 8 is an A / A. D part, 9 is a speaker part, 10 is a D / A part, 11 is a display part, 12 is a bus line. In FIG. 2, reference numerals 13 to 16 denote interface units, 20 denotes a main processing unit, 21 denotes an AV function unit, and 22 denotes an audio recording unit.
[0009]
Of these embodiments, the embodiment of FIG. 1 is of an integral configuration.
The operation of this embodiment will be described. The CPU 1 starts control according to a recording instruction from the operation unit 2, the video is recorded by the CCD (camera) unit 5, and the audio signal is recorded by the microphone unit 7. The video signal from the CCD (camera) unit 5 is converted into a predetermined format by the image format generation unit 6, and the audio signal from the microphone unit 7 is converted into a digital signal by the A / D unit 8. Both are once recorded in the memory 3 and finally recorded in the storage memory 4. The memory 3 is used not only for temporarily recording recorded signals but also for recording programs and data.
[0010]
The storage memory 4 has a role of recording and storing the edited video / audio and reproducing it as necessary. The contents of the storage memory 4 are reproduced by the CPU 1 driving the storage memory 4 in accordance with a reproduction instruction given by the operation unit 2, the video signal is displayed on the display unit 11, and the audio signal is sounded and output from the speaker unit 9. The
[0011]
On the other hand, the embodiment of FIG. 2 employs a configuration in which the main processing unit 20, the AV function unit 21, and the audio recording unit 22 are separated. Each section of the AV function unit 21 and the main processing unit 20 are connected to the interface units 13 to 16 via the bus line 12, respectively. The AV function unit 21 may be an integrated device as shown in FIG. 1 separated through an interface, or a normal AV device connected to the main processing unit 20 using digital input / output. There may be. In the embodiment of FIG. 2, the basic operation is exactly the same as that of FIG.
[0012]
In the case where the recording apparatus is integrated as shown in FIG. 1, the main processing unit 20 and the AV function unit 21 must be in the same place. However, in the case of the separation type configuration as shown in FIG. The position and the position of the processing device can be separated. Further, if the audio recording unit 22 is separated from the other parts, recording can be performed with the CCD (camera) unit 5 and the microphone unit 7 separated to some extent.
Further, if the audio recording unit 22 is configured by combining the FM transmission / reception units 17 and 18 as shown in FIG. 3, external audio from a long distance can be received by FM radio waves and linked to an image signal.
An object of the present invention is to edit the audio signal temporarily stored in the memory 3 by a simple method and store the video signal and the edited audio signal in the storage memory 4 in a corresponding manner.
[0013]
FIG. 4 schematically shows the contents of a temporary audio recording memory block in the memory 3.
This memory is organized in the range from address △△△△ to address ○○○○, and recording to this memory starts from address Δ △△△, and once it reaches the address ○○○○, it again becomes Δ △△ This is done by returning to address △ and overwriting.
[0014]
FIG. 5 shows a flowchart relating to a process of editing an audio signal using the memory block for temporary recording of audio and recording it in the storage memory 4 in association with the image signal. In the following, the operation and processing of audio recording editing will be described with reference to the flowchart of FIG.
First, when an image capture mode (photographing mode) is designated in step 101, recording of an audio signal by the microphone unit 7 is started on the audio side (step 102). On the other hand, on the image side, the recording CCD (camera) unit 5 waits for video recording (step 106). (Alternatively, it is possible to start and execute recording of audio signals and video recording independently by other designation methods, but since they are not particularly related to the present invention, detailed description thereof is omitted.)
[0015]
In the state of step 102, the recording on the voice side is continuously performed. The recording is sequentially performed from the address Δ △ ΔΔ of the memory block in FIG. 4 to the address XXX, and as described above, When the address XX is full, it returns to the address △△△△ and is overwritten in a ring shape.
[0016]
When an image capturing event is generated by the user's operation on the image side, and the capturing of the image is completed and temporarily stored in the memory 3 (step 107), a recording stop instruction is issued from the recording CCD (camera) unit 5 on the image side. Sent to the audio side. As a result, the audio side transitions to the state of step 103 and starts reproducing the effective range of the audio signal recorded in step 102.
[0017]
By the way, the state of the memory block when a recording stop instruction is sent from the image side to the sound side is as shown in FIG. In FIG. 6, the point a corresponds to the time when writing is performed and a stop instruction is given.
From t1 time before point a to t2 time after point a is assumed to be effective voice data for this recording. These times t1 and t2 are times that can be arbitrarily set separately by the user. In FIG. 6, the temporary effective audio data at this time is from ▲▲▲▲ to ●●●●.
In step 103, the effective audio data is repeatedly reproduced. This state is continued until the start / end address change operation in step 104 is executed and terminated.
[0018]
The start / end address changing operation in step 104 is executed by operating a predesignated button. The relationship between them is shown in FIG.
For example, the setting of the start address of the effective voice data is performed by pressing the button A determined for changing the start address. The start address moves to the point of time a by pressing the first button A, and every time the button A is pressed, time t3 is given, such as a, a ′, a ″ in FIG. 7A. To go.
During this time, the repeated reproduction of the effective audio data in step 103 is repeated within this newly set range. The start address newly set here cannot be the start address ▲▲▲▲ of the first temporary effective range. Also, this pressing may be repeated once until it is confirmed. In order to determine the start address, the button A may be kept pressed for a certain period of time. If button A is kept pressed for a certain period of time, the currently specified start address is confirmed.
[0019]
Similarly, the end address of the valid voice data is set by pressing the button B determined for changing the end address. The end address is at the first point b, that is, the address ●●●●, and every time the button B is pressed, the time is incremented by time t3 as shown by b and b 'in FIG. The newly set end address cannot call the already set start address. In order to determine the end address, the button B may be kept pressed for a certain period of time. If the button B is kept pressed for a certain period of time, the currently specified start address is fixed.
In this way, both the start address and the end address are confirmed, and when the address from the address is determined as the final effective range as shown in FIG.
[0020]
In step 105, as shown in FIG. 8, the audio signal in this range is sent from the address of the temporary recording in the memory 3 to the storage memory 4 from the address of the storage memory 4 ◇◇◇◇ It is transferred to □□□□ and recorded.
When the audio signal is thus determined, the video signal stored in step 107 is read out at the same time, and is linked to the audio signal and recorded in the storage memory 4.
Finally, the audio signal is pasted on the image signal, and the process ends (step 108). The method for pasting the audio signal to the image signal is realized by a method of recording with the same label or matching the track positions of the image and the audio.
[0021]
As a result, the image signal and the edited audio signal paired with the image signal can be simultaneously retrieved from the storage memory 4 and read out simultaneously, and can be simultaneously reproduced from the display unit 11 and the speaker unit 9 respectively.
[0022]
In the above description, it has been described that the image signal is temporarily stored in the memory 3 in step 107 and then transferred to the storage memory 4 in step 108. However, depending on the nature of the storage memory 4, the storage memory 4 may be used from the beginning. And an audio signal may be linked thereto. In this case, the capacity of the memory 3 required for temporary storage can be made much smaller.
[0023]
In the above description, the stored image signal is described as a still image signal. However, it may be a moving image.
In the case of a moving image, the moving image is set to a still (still image) playback state prior to the audio start / end address changing operation (step 107), and the recording position of the moving image is the same as in the case of the still image. By adapting to the audio signal, it is possible to attach the audio to the moving image.
[0024]
According to the method described above, the user arbitrarily selects a predetermined range from the recording of the audio signal before and after the image capture once recorded, and the audio signal in the selected range is stored and recorded in association with the image signal. be able to. As a result, since the audio signal is not automatically performed in conjunction with the image capture on the accumulated recording, the beginning and end of the audio signal can be edited well.
In addition, a pair of the image signal and the audio signal edited in this way can be communicated and transmitted using a communication line, which is also effective for use for such purposes.
In addition, since a fixed length portion of the memory 3 is allocated and used in a ring shape as a storage area used for temporary storage of audio, relatively few memory sources can be used effectively.
[0025]
