I have.

[0007] However, none of these contrivances takes into account the setting of information relating to the time interval (interval time) of the repeated audio information output. This has caused some problems to be solved.

That is, for example, when the pronunciation information of each English word is applied to a teaching material for English learning recorded on paper as an optically readable code, a fixed time is always required regardless of the read code. The pronunciation of the English words contained in the code is repeatedly output from the information reproducing device according to the interval, so that the learner can perform the English word of any length within the fixed time interval regardless of the length of the English word.

[0020]

Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] In the embodiment of the present invention, an information reproducing apparatus for optically reading a dot code 10 shown in FIG. 1A will be described as an example.

First, the dot code 10 will be described in detail.

The dot code 10 recorded on a sheet-like recording medium 12 such as paper has a one-dimensional or one-dimensional shape in which a block 16 whose four corners are surrounded by markers 14 shares the marker 14 with an adjacent block. Are two-dimensionally connected.

The block 16 includes a pattern code 18 and a block header 2 on each side sandwiched by the markers 14 at the four corners.
0 is arranged therein, and the block user data 22 is arranged therein.

The marker 14 is used to detect the approximate position of the block 16 when the optically readable information reproducing device 24 reads the dot code 10.
Further, the pattern code 18 arranged at the position between the two markers 14 is used for accurately calculating the read position of the white or black dot of the block header 20 and the block user data 22.

The block header 20 records block ID information (= block address) for determining the order of combination of the user data obtained by dividing the recording data of the block user data 22 into blocks.

The block user data 22 is subjected to recording modulation in which predetermined division data of the total user data stored in the dot code 10 does not produce a print shape similar to that of the marker 14, and is recorded as a black and white dot pattern. Is done.

The information reproducing device 24 that reads the dot code 10 divided into blocks as described above uses the dot code 1
It is not necessary to take an image of the entirety of the dot code 10 at a time, and the imaging area is set to contain several blocks 16. The block user data 22 stored in each block 16 can be stored in a predetermined order based on the block ID in the block header, and finally, all the user data in the dot code 10 can be read. Here, it is premised that the information reproducing apparatus 24 performs the imaging operation every predetermined period sufficiently shorter than the manual scanning speed.

Accordingly, it is possible to reduce the size of the information reproducing device 24 with respect to the dot code 10.

The details of the above dot code reading process are described in Japanese Patent Application Laid-Open No. Hei 8-171620 by the present applicant.

FIG. 2 is a functional block diagram of a main part of the information reproducing apparatus 24 according to the first embodiment of the present invention.

That is, although not specifically shown, the imaging unit 26 is composed of a lens, an imaging device such as a CCD, and an LED, and the dot code 10 illuminated by the LED is formed on the imaging device by the lens. The captured image is output to the image processing unit 28.

The image processing unit 28 performs an equalizing process for emphasizing each dot and a binarization process on the dot code image picked up by the image pickup unit 26,
The digitized dot code image is output to the block extracting unit 30.

The block extracting unit 30 is provided with the image processing unit 2
And a buffer memory (not shown) for temporarily storing the binarized image processed in step 8. The dot code 10 for the binarized image stored in the buffer memory is provided.
The approximate position of the block 16 is determined by the detection of the marker 14 constituting. Further, based on the approximate position, the pattern code 18 is extracted from the binary image, and the multiple read dot positions of the block header 20 and the block user data 22 arranged in the block are accurately calculated.
A process of converting the dot color (whether a black dot or a white dot) at the read dot position into bit data (1 or 0) is performed. Then, of the converted bit data,
The block user data 22 includes the marker 14 as described above.
Since the recording modulation for discriminating the recording modulation is performed, the demodulation processing for demodulating the recording modulation is performed in a predetermined plural dot unit.

The block data storage memory 32 is a memory for storing demodulated data of the block user data 22 in accordance with the block ID information recorded in the block header 20 extracted from each block by the block extractor 30. .

The data restoration processing unit 34 uses the rearranged data stored in the block data storage memory 32 based on the data rearrangement performed in advance for the burst error (to thereby randomize the burst error). And an error correction process for an error correction code configured in advance to correct a predetermined number of random errors to generate restored data.

The output processing unit 36 stores the restored data from the data restoration processing unit 34 in the restored data storage memory 38 and uses the block ID information output from the block extraction unit 30 to output the restored data storage memory 38
And output control for the restored data recorded in the restored data storage memory 38.

The output unit 40 outputs the restored data stored in the restored data storage memory 38 by the output processing unit 36. If the restored data is audio, for example,
The output unit 40 performs D / A conversion on the restored data that is digital data, amplifies the converted analog signal, drives a speaker, and outputs sound. When the restored data is, for example, text or an image, the data is displayed at a predetermined position on a display (not shown).

FIG. 1B is a diagram showing a logical data format recorded in the dot code 10.

Here, the dot code 10 includes, for example,
Perceptually recognizable units such as voice, text, images (including moving images), and tone information (hereinafter, this unit is referred to as subset data 42) are recorded separately.

The subset data 42 is roughly composed of two areas, a subset header 44 and a subset user data 46. The subset header 44 further includes a subset number 44A, a repetition number 44B, a repetition output waiting time 44C, a jump destination subset. An area for recording parameters such as a number 44D and a jump destination subset output waiting time 44E is prepared. On the other hand, the subset user data 46 records speech, text, images (including moving images), musical sound information, and the like, which are perceptible and recognizable information.

FIG. 3A shows a waveform of an output sound when a conventional dot code is read by the information reproducing device 24. That is, when a conventional dot code is read, recorded audio data is only reproduced once.

On the other hand, FIG. 3B shows a dot code 10 according to the first embodiment in which audio data is recorded in the logical data format shown in FIG.
3 shows a waveform of an output sound when the information reproducing device 24 reads the “. That is, in this example, the audio data recorded as the subset user data 46 is reproduced three times, and the waiting time for the first to second audio reproduction or the second to third audio reproduction is set to a predetermined interval. Can be.
In the logical data format for this example, “3” is set to the number of repetitions 44B and the repetition output waiting time 4
4C has the output waiting time "W1" from the first time to the second time.
And the output waiting time “W2” from the second time to the third time are recorded. Of course, if the repeated output waiting time is constant regardless of the number of times (W1 = W2 =...), It is also possible to record one predetermined output waiting time together with information indicating that it is one value.

The sound data of this example is very effective when recording, for example, the sound of a bird. This is because the bird's cry has a certain periodic pattern and a predetermined silent period. Furthermore, in order to prevent artificial periodicity from being felt in such repeated playback, a silent period (FIG. 1)
(Recorded in the repetitive output waiting time 44C in the logical data format of (B)) is not a fixed value. For example, the shortest time and the longest time of the unvoiced period are recorded in this recording area. And the output processing unit 3 sets a random time for each reproduction count within the longest time.
6 may control the silent period.

By performing such control, more natural reproduction can be performed, and the data amount of audio data recorded in the dot code 10 can be suppressed.

In particular, FIG. 1B shows a dot code 1
Although an example in which there is one subset data in 0 has been described, a plurality of subset data may be recorded in one dot code 10.

FIG. 4 shows an example of application to output control of a plurality of subsets obtained by combining a plurality of dot codes, in addition to controlling output of a complete subset using only one dot code.

In this example, a dot code 10 is recorded for each bar of a staff notation on a musical score 48 as a recording medium. Each dot code 10 has a subset data of 1
, The identification IDs of which are... C, D,.
G and H.

As an output operation, for example, when the operator scans only the dot code 10 of the subset C by the information reproducing device 24, the musical sound or singing voice of only this bar is reproduced, and the subsets C to C in the musical score are reproduced. When the H dot code 10 is scanned, a continuous musical sound or singing voice is reproduced for the scanned bar. The bar 50 is a bar to be repeated, and when the dot code 10 of the subset D is scanned, this bar 50 is read.
Only the musical tone or singing voice is repeatedly reproduced.

In order to realize such an output operation, the block ID information recorded in each block header 20 of the dot code 10 is uniquely determined for each subset (for example, the subset C is stored). Dot code 10 has block ID 100 to 199, subset D
Is stored in the dot code 10 whose block ID is 2
00 to 299,...).
The block user data 22 of the scanned dot code 10 can be temporarily and continuously stored in the block data storage memory 32 based on each block ID. The block user data 22 stored in 32 can be restored to desired subset data (IDs such as C and D).

As described above, in the example where a single dot code 10 and a meaningful output operation can be performed even when a plurality of dot codes 10 are collected, the jump destination subset of the subset header 44 shown in FIG. The area of the number 44D and the jump destination subset output waiting time 44E is used.

FIG. 5 shows the output operation sequence for the three subset data and the restored data storage memory 3 of the information reproducing apparatus 24 in which the dot code 10 has already been scanned.
8 shows a specific example of the three subset data stored in FIG.

The order of the output operation is as follows. Subset
C audio data C_vPlay → Y₁Output wait time →
Audio data D of Buset D_vPlay → X₂Waiting for output
Between → audio data D of subset D_vPlay → Y₂Output
Waiting time → Play audio data of subset E → Y₃Out of
Power wait time → audio data C of subset C_vPlay → Y
₁Output waiting time → subset D audio data D_vRe
Raw → X₂Output waiting time → subset D audio data D
_vPlay → Y₂Output waiting time → audio data of subset E
Data E_vPlay → Y₄After the output wait time of
Is not present in the restored data storage memory 38.
The output processing unit 36 determines that the output is correct and stops the output.

The set values for each subset header 44 area for performing such an output operation are as follows.

That is, the number of repetitions 44B and the repetition output waiting time 44C of the subset C are each "0", and the jump destination subset number 44D ends with the next subset number "D" to be reproduced and its information. "0" indicating
However, the jump destination subset output waiting time 44E indicates “Y
₁ "is set.

The number of repetitions 44B of the subset D is “1”, the repetition output waiting time 44C is “X ₂ ”, and the jump destination subset number 44D includes the number “E” of the next subset to be reproduced and its information. “0” indicating the end is the jump destination subset output waiting time 44E.
Is set to “Y ₂ ”.

Then, the number of repetitions 44B of the subset E
And the repeated output waiting time 44C is “0”, and the jump destination subset number 44D ends with the number “C” of the subset to be reproduced next, the number “F” of the subset to be reproduced after the second reproduction, and the information thereof. "0" indicating that
However, in the jump destination subset output waiting time 44E, a waiting time “Y ₃ ” until reproducing the subset C and a waiting time “Y ₄ ” before reproducing the subset F are set.

FIG. 6 is a flowchart showing a series of processes from when the information reproducing device 24 reads the dot code 10 to when the information reproducing device 24 performs an output operation.

First, a controller (not shown) periodically checks whether or not the operator has pressed the scan start button 52 of the information reproducing device 24 (step S10).

Then, it is determined whether or not the scan start button 52 has been pressed, that is, whether or not to start code reading (step S12).
If is not pressed (if code reading is not started), the process returns to step S10.

On the other hand, when the scan start button 52 is pressed (when code reading is started), block reading processing is started (step S1).
4). That is, in this block reading process, the blocks 16 constituting the dot code 10 are extracted from the captured image captured in time series, and the block user data 22 stored in the block 16 is stored in the block data based on the block ID. It is stored in the memory 32, and the end of the scan operation of the dot code 10 is detected when the scan start button 52 is released.

After the scan operation is completed, data restoration processing is performed on a plurality of block user data stored in the block data storage memory 32 (step S1).
6). In this data restoration processing, deinterleaving and error correction are performed, and the subset data is restored and stored in the restored data storage memory 38.

Thereafter, it is determined whether or not error correction is possible at the stage of restoring the subset data (step S18).
If it cannot be corrected, the process returns to step S10.

On the other hand, if the correction is possible,
First block I constituting the read dot code 10
D is acquired (step S20).

Then, it is determined whether or not the obtained top block ID is a predetermined value (here, “1”) (step S 22). If it is the predetermined value, the subset already stored in the restored data storage memory 38 is determined. The data (excluding the subset data restored by the current scan) is deleted (step S24). On the other hand, if the acquired head block ID is not the predetermined value, the erasure in the memory is not performed.

Thereafter, the subset data stored in the restored data storage memory 38 is output as described later in detail (step S26). When the output is completed, the process returns to the step S10, and returns to the dot code 10 reading standby state.

In this flowchart, an example has been shown in which the old subset data in the restored data storage memory 38 is deleted when a predetermined block ID is detected. May intentionally delete old subset data by operating a switch.

FIG. 7 is a flowchart showing an example of the process of “outputting the subset data stored in the restored data storage memory 38” executed in step S26 in more detail, which will be described below. I do.

That is, first, the restored subset number of the currently scanned dot code 10 is set as the output subset number X (step S26A).

Subsequently, it is determined whether or not the output subset number X exists in the restored data storage memory 38 (step S26B). If there is no subset having the subset number X in the restored data storage memory 38, the process returns to step S10 in FIG.

On the other hand, when the subset of the subset number X exists in the restored data storage memory 38, the header of the subset data of the subset number X is extracted, and the number of repetitions RN, the repetition output waiting time RWT, the jump destination subset number NX and a jump destination subset output waiting time NWT are acquired (step S26C).

Then, following the acquisition of the header parameter, the user data (voice) of the subset number X is output (step S26D).

After outputting the voice, it is determined whether or not the number of repetitions has reached the obtained number of repetitions RN of the header (step S26E). A silent sound for the waiting time RWT is output (step S26F), and the above step S26D is repeated again.

The number of repetitions is the number of repetitions R
At the time when the number becomes equal to N, a silence sound for the output waiting time NWT of the acquired jump destination subset is output (step S26G), and the jump destination subset number NX is set to X.
(Step S26H), and the above-described Step S26
Return to B.

As described above, with respect to the subset data recorded in each dot code 10, the output operation of the subset itself and the output operation between different subset data of different dot codes are described, so that a more complicated desired data can be obtained. The output operation can be realized without the operator having to scan all the codes many times.

In the present embodiment, the subset data is audio data, and the output control information is the number of repetitions and the waiting time until output, the jump destination to another subset, and the waiting time until the output. As described above, other output control information such as a reproduction speed and a change in volume (fade-in or fade-out) may be prepared.

Further, even when the subset data is text, image, etc., the display on the display device is switched in chronological order (the simplest display example is blinking display). Needless to say, the output control information thus obtained can be similarly used.

[Second Embodiment] Next, a description will be given of an information reproducing apparatus 24 which is more convenient for an operator as a second embodiment of the present invention with respect to the above-described repeated output operation.

FIG. 8 is a functional block diagram of an information reproducing apparatus 24 according to the second embodiment.

The difference from the first embodiment is the conversion table storage memory 54. Only this portion will be described below, and the other description will be omitted.

That is, as shown in FIG. 9, the conversion table storage memory 54 stores the ID numbers of the subset data created by the output processing unit 36 and restored by the data restoration processing unit 34 and the block extraction unit 30. This is a memory for storing a correspondence table with the extracted block IDs.
This is used to convert the block ID input to the output processing unit 36 into the ID number of the subset data by reading the part of the dot code 10 by the information reproducing device 24 again by the operator.

That is, by preparing such a conversion table storage memory 54, the dot code 1 once read
When it is desired to repeatedly output the dot code 10 again, the information reproducing device 24 is placed on the dot code 10 without scanning the entire dot code 10 again, and a part of the dot code 10 is The output can be repeated simply by reading by a momentary click.

For example, as shown in FIG. 4, a musical score (singing voice) in which a plurality of dot codes 10 form a single meaning, such as a musical score 48 in which each bar is represented by one dot code 10. And individual dot code 1
Such an operation is particularly effective when it is possible to listen to a musical sound (singing voice) in each bar even with 0 itself.

In order to enable the above operation, the information reproducing apparatus 24 needs at least an image pickup section 26 having an image pickup area 26A as shown in FIG. The imaging area 2
6A is an area obtained by the imaging unit 26 of the information reproducing device 24 in one imaging process, and has an area large enough to image at least two blocks 16 constituting the dot code 10 at a time. I have. With such an imaging area, even if the operator places the information reproducing device 24 on the dot code 10 to some extent, one block 16 in the dot code 10 can be imaged reliably. One block address of the block 16 constituting the dot code 10 can be extracted by the block extracting unit 30.

After reading all the dot codes 10 in the musical score 48 once using the information reproducing apparatus 24, the operator wants to listen again to only the bars corresponding to the subsets C and D, for example. In this case, while pressing the scan start button 52 of the information reproducing apparatus 24,
By merely placing the information reproducing device 24 on one dot code 10, it is possible to select a target subset for repeated reproduction output and to trigger the reproduction output. The need to perform a scanning operation with the device 24 is eliminated.

FIG. 11 shows a flowchart relating to the processing of the second embodiment.

First, a controller (not shown) periodically checks whether or not the operator has pressed the scan start button 52 of the information reproducing device 24 (step S10).

Then, it is determined whether or not the scan start button 52 has been pressed, that is, whether or not to start code reading (step S12).
If is not pressed (if code reading is not started), the process returns to step S10.

On the other hand, when the scan start button 52 is pressed (when code reading is started), block reading processing is started (step S1).
4). That is, in this block reading process, the blocks 16 constituting the dot code 10 are extracted from the captured image captured in time series, and the block user data 22 stored in the block 16 is stored in the block data based on the block ID. It is stored in the memory 32, and the end of the scan operation of the dot code 10 is detected when the scan start button 52 is released.

After the end of the scan operation, data restoration processing is performed on a plurality of block user data stored in the block data storage memory 32 (step S1).
6). By this data restoration processing, deinterleaving and error correction are performed, and the subset data is restored.
The data is stored in the restored data storage memory 38.

Thereafter, it is determined whether or not error correction is possible at the stage of restoring the subset data (step S18).
If the correction is impossible, the process jumps to step S32 described later.

On the other hand, if the correction is possible,
First block I constituting the read dot code 10
D is acquired (step S20).

Then, it is determined whether or not the obtained head block ID is a predetermined value (here, “1”) (step S22).

Here, if the acquired head block ID is a predetermined value, the subset data already stored in the restored data storage memory 38 (excluding the subset data restored by the current scan) is deleted ( In step S24, a correspondence table between the block ID detected at the time of code scanning and the restored subset number as shown in FIG. 9 is created and stored in the conversion table storage memory 54 (step S30).

On the other hand, if the acquired top block ID is not the predetermined value, the process proceeds to step S30 without erasing the memory, and the correspondence table is created and stored in the conversion table storage memory 54. .

After the correspondence table is created and stored in the conversion table storage memory 54, the restored data storage memory 38
It outputs the subset data stored in (step S26). When the output is completed, the process returns to the step S10, and returns to the dot code 10 reading standby state.

On the other hand, if it is determined in step S18 that the error correction could not be performed during the data restoration processing, that is, if it is determined that a part of the dot code 10 has been read, the details will be described later. A subset to be repeatedly output is determined based on the block ID read at the time of scanning, and the subset data is repeatedly output (step S32). When the repetitive output is completed, the process returns to step S10, and returns to the dot code 10 reading standby state.

Here, the details of the process of repeatedly outputting the subset data executed in step S32 will be described with reference to the flowchart of FIG.

First, the block ID read by the information reproducing apparatus 24 is converted into a subset number, and is converted into a predetermined memory area X [n] (n = 0 to N-1, where N is the number of different subsets). One or more subset numbers are stored (step S32A). Here, the conversion process of the block ID into the subset number is a process of searching for a subset number including the block ID by using a correspondence table between the block ID and the subset number as shown in FIG. The read block ID is m
, The subset number is B.

Next, the counter n of the memory area X [n] is reset to "0" (step S32B), and
