DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an audio code recording apparatus for converting audio information into an optically readable code image and recording the code image on a print recording medium.

[0002]

2. Description of the Related Art Conventionally, various media such as a magnetic tape and a magneto-optical disk have been known as media for storing audio and video information. However, even if these media are made in large quantities, the unit price is somewhat expensive, and their storage requires a large space.

[0003] Furthermore, if it is necessary to deliver a medium on which voice is recorded to another person at a remote place, it takes time and effort to transport the medium or take it directly. There were also problems.

[0004] To deal with such a problem, multimedia information including at least one of audio information, video information, and digital code data can be transmitted by facsimile and a large amount of images can be copied at low cost. An apparatus for recording information, that is, a plurality of dots as encoded information in a two-dimensional code pattern in which a plurality of dots are two-dimensionally arranged on an information recording medium such as paper is disclosed in Japanese Patent Application Laid-Open Nos. 6-231466 and 7-325897. No., for example.

In the above-described apparatus, when audio information is handled, a large amount of data is required to record the audio information on the information recording medium as it is, and the information recording medium is used in large amounts. Therefore, compression of audio data is generally performed.

As a method of compressing the audio data, a method which is an extension of linear pulse coding modulation is employed, and is performed for each frame unit at a fixed time interval (for example, one frame = 30 m).
s), assuming the amplitude distribution of the audio signal as an exponential distribution,
There is a method of logarithmic companding PCM that performs logarithmic companding and then performs quantization.

[0007] This method is a compression method of audio data that can obtain the same SN ratio with a smaller number of bits at the time of encoding as compared with ordinary PCM. In addition, when inputting audio information, it may be difficult to record the expected audio information in a single input. Therefore, a specified area may be deleted from the input audio information,
Editing processing operations such as copying and moving are performed.

When the above-described apparatus is considered in consideration of the above, a configuration as shown in FIG. 17 can be considered. That is, in FIG. 17, the voice input unit 1 inputs voice and stores it in the memory 2.

The input voice data stored in the memory 2 is
Editing is performed by the audio data editing unit 11. On this occasion,
An operation screen for the editing operation is displayed on the display unit 12, and an editing instruction is performed by the operation unit 13.

Confirmation of the edited audio data by reproduction is performed by the audio output unit 10. The result of editing the audio data by the audio data editing unit 11 is reflected on the memory 2 and stored again.

The audio data compression section 3 compresses the edited audio data stored in the memory 2. The audio data compressed by the audio data compression unit 3 is stored in the memory 4.

The compressed audio data stored in the memory 4 is
The encoding process is performed by the encoding unit 5 to generate code image data that can be printed and recorded on the information recording medium. The code image data generated by the encoding unit 5 is printed on an information recording medium as an optically readable code image by a printing unit 9.

[0013]

However, in the above-described apparatus, since the audio data immediately after the input is edited, a memory for storing the audio data in accordance with the input time of the audio is required. Further, after the input audio data is edited, the audio data is compressed. However, this also requires a memory for storing the compressed audio data, and the memory in the apparatus becomes large.

Therefore, an increase in the capacity of the memory leads to an increase in cost, and a large memory space is required, which complicates a circuit in the device. The present invention has been made in view of the above circumstances, and in a voice code recording device that records voice data as an optically readable code image, a voice code recording device that suppresses a memory capacity related to voice data input as much as possible. It is an object of the present invention to provide a voice code recording device that enables editing.

The audio input unit 20 inputs audio in units of frames, and the input audio data is sequentially output to the audio data compression unit 21. The audio data compression unit 21 determines whether the input audio data output by the audio input unit 20 in a frame unit is voiced or silent, and sequentially records the determination result in the memory 22 as voiced / silent flag data. Go.

For example, when it is determined that there is a sound, the value is "1".
When it is determined that there is no sound, data of "0" is sequentially recorded in frame units. When the audio data compression unit 21 determines that the input audio data output from the audio data input unit 20 is sound, the audio data compression unit 21 performs a compression process on the input audio data on a frame basis and records it in the memory 22. If it is determined that there is no sound, the compression of the input voice data is not performed and the recording in the memory 22 is not performed.

The audio data compression unit 21 also records various parameters related to compression when the input audio data is compressed in the memory 22. Usually, the determination as to whether or not there is sound is made by comparing the average amplitude of audio data with a threshold level.

As described above, at the end of the input of the voice, the memory 22 stores the voice / non-voice flag data of the input voice, the compressed voice data of the voiced portion, and the compression parameters for voice compression.

For example, a display such as the voice data sound / silence display screen 33 shown in FIG. 2 is performed. In this case, the relationship between the sound / silence flag data and the display format of the sound / silence portion is as shown in FIGS. 2 (A) and 2 (B).

Further, a scale axis 40 representing the actual time indicating the actual time before the compression of the input audio data can be displayed on the sounded / silent display screen 33 of FIG. On the scale axis representing the real time, since the input audio data is input in units of frames of a fixed time (for example, every 30 ms), the result can be displayed by simple addition of time.

The operation section 32 gives an operation instruction for editing the compressed audio data to the compressed audio data editing section 30. The main editing operation instructions given by the operation unit 32 to the compressed audio data editing unit 30 include designation of an area to be edited of audio data and deletion, copying, and movement of the designated area of audio data.

The method of these editing operations will be described with reference to FIGS. When performing an editing operation such as deletion, copying, or moving, it is necessary to first specify an area of audio data to be edited.

As one method of specifying the area of the audio data, the operations shown in FIGS. 3A to 3D are performed. FIG. 3A shows a sound / silence portion display screen immediately after voice input, in which a cursor is moved to designate a region start position at the beginning of a region to be edited.

The cursor is moved in FIG.
When the area start position is designated, the state becomes as shown in FIG. 3B, and the area start position is determined. The designation of the area end position is also performed by moving the cursor, but display or the like can be performed in a form in which the area between the area start position and the area end position is inverted with respect to other areas.

When the end position of the area is designated in FIG. 3C, the edit target area of the audio data is determined as shown in FIG. 3D. Next, an editing method for deleting, copying, and moving audio data will be described with reference to FIG.

FIG. 4A shows a state where the edit target area of the audio data in FIG. 3 has been determined. When the deletion is designated by the operation unit 32, as shown in FIG. 4B, the sound / silence flag stored in the memory 22 corresponding to the audio data of the edit target area in FIG. The data and the compressed audio data are deleted by the compressed audio data editing unit 30.

The operation unit 32 is shifted from the state shown in FIG.
