Description

  The present invention relates to data communication of a mobile terminal equipped with a display and a camera, and more particularly to a technology of data communication between mobile terminals that are close to each other.

In recent years, two-dimensional barcodes (hereinafter referred to as “two-dimensional codes”) in which the amount of information that can be recorded is greatly increased compared to so-called one-dimensional barcodes have become widespread.
In addition, mobile terminals such as mobile phones have become more multifunctional, and many mobile terminals have a display and a camera.
Therefore, the mobile terminals can directly exchange data by displaying the two-dimensional code on the display of the mobile terminal and reading the displayed two-dimensional code with the camera of another mobile terminal. . For example, each other's profiles are exchanged.

Although the amount of information that can be recorded with a two-dimensional code has increased, there are naturally limitations, and depending on the amount of information to be exchanged, there are cases where a plurality of barcodes must be used. Thus, a technique for smoothly reading a plurality of continuous barcodes has been developed (see Patent Document 1). In this technique, bar codes are continuously displayed at the same location at predetermined time intervals, so that continuous bar codes can be sequentially read without moving a conventional reading device.
JP 2003-317051 A (Patent No. 3534250)

However, there is no guarantee that the data can be read within the predetermined time displayed, and if the data cannot be read normally, there is a problem that the original data cannot be restored due to data loss.
Therefore, an object of the present invention is to provide a portable terminal that can restore the original data without fail even if a plurality of barcodes are read continuously.

  In order to solve the above problems, an image reading system of the present invention is an image reading system including a first portable terminal having a display and a second portable terminal that sequentially reads a plurality of images. One mobile terminal includes image display means for displaying one of a plurality of images in a predetermined display order on the display, and sound detection means for detecting sound, and the image display means displays one image. When a specific sound is detected by the sound detection means during the display, the next image of the one image in the display order is displayed, and the second portable terminal displays the image displayed on the display as 1 Image reading means for sequentially reading each one and sounding means for sounding a predetermined sound are provided, and the image reading means sounds a predetermined sound by the sounding means each time one image is read.

  Further, the mobile terminal of the present invention is a mobile terminal having a display, and an image display means for displaying one of a plurality of images having a predetermined display order on the display, a sound detection means for detecting sound, The image display means displays the next image of the one image in the display order when the sound detection means detects a specific sound while the image is being displayed. To do.

Since the portable terminal according to the present invention has the above-described configuration, the portable terminal on the image reading side can notify that the image has been read with a specific sound when the image can be read. The image display side can display the next image after confirming that the image has been read.
Therefore, when reading a plurality of continuous image data, skipping does not occur, so that all images can be read reliably.

Here, the image refers to an image displayed on a display, such as a so-called bar code, in addition to a photograph, a picture, a character, and the like.
The image displayed on the display by the image display means of the first portable terminal is a barcode, and the second portable terminal further analyzes the barcode that is the image read by the image reading means. It is good also as providing an analysis means.

Thereby, since barcodes are exchanged between portable terminals, meaningful information can be converted into barcodes and data exchange can be performed between portable terminals.
The barcode includes various types of barcodes such as a one-dimensional barcode and a two-dimensional barcode such as a stack method or a matrix method. For example, JAN barcode, PDF417, Maxi Code, QR (Quick Response) code (registered trademark), etc. are included.

  The portable terminal further includes sound storage means for storing sound, and sound determination means for determining whether or not the stored sound data and the sound detected by the sound detection means are the same. And the image display means is in the display order only when the sound determination means determines that the sound detected by the sound detection means is the same as the sound data stored in the sound storage means. The next image after the one image may be displayed.

As a result, only a specific sound can be interpreted as a cue when the image is read, and it can be confirmed that the image has been read, so the next image is displayed while the image is not being read. You will be able to eliminate that.
The portable terminal further includes sound acquisition means for acquiring sound from the outside and storing the acquired sound in the sound storage means, and the sound determination means includes the sound acquired and stored from the outside It may be determined whether the sound detected by the sound detection means is the same.

Furthermore, the portable terminal of the present invention is a portable terminal that sequentially reads a plurality of images displayed by other terminals, and includes an image reading means for sequentially reading the images one by one and a sounding means for generating a predetermined sound. The image reading means sounds a predetermined sound with the sound generation means every time one image is read, and when the read image is the same image as the previous read image, A predetermined process is performed.

Thereby, since duplication of the read image can be detected, it is possible to eliminate processing of useless images.
The image may be a barcode, and the same image may have the same barcode.
As a result, duplication of the read barcode can be determined, so that useless data can be prevented from being stored.

  Further, in the image reading method used in the system including the first portable terminal having a display and the second portable terminal that sequentially reads a plurality of images, the display order of the first portable terminal is determined in advance. An image display step for displaying one of a plurality of images on the display; and a sound detection step for detecting a sound, wherein the image display step is performed in the sound detection step while displaying one image.

<Overview>
Among the mobile terminals according to the present invention, the mobile terminal on the bar code display side displays the next bar code at the timing of receiving a signal indicating that the bar code has been normally read from the mobile terminal on the reading side. Therefore, the mobile terminal that reads the barcode sends a signal to that effect when the barcode is successfully read.

Thus, by displaying the next barcode with a cue as a trigger, data loss due to skipping can be prevented.
As a cue, in this embodiment, a shutter sound that is emitted when the image is taken with a camera is used. Usually, it sounds at the time of photographing with a camera and is used in the present invention.
Further, in the portable terminal on the image reading side, whether or not the read image is the same as the image read immediately before is checked, and if it is the same, it is discarded.

When the same image can be read, it means that the shutter sound cannot be picked up by the mobile terminal on the image display side, so a shutter sound is emitted when the image is read, regardless of the overlap of the read images. And
In this embodiment, data exchange between mobile phones will be described, and image data to be exchanged is a QR code (registered trademark, the same applies hereinafter) which is a kind of two-dimensional code.

Next, the QR code storage unit 1400 stores a QR code. Details of the stored QR code will be described below with reference to FIG.
FIG. 4 is a diagram illustrating an example of continuous QR codes.

In the present embodiment, it is assumed that character data 10 that is data to be exchanged is converted into a plurality of QR codes (30, 31 to 32) in advance.
Here, it is assumed that the character data 10 is an amount that does not fit in one QR code. A plurality of pieces of divided data (20, 21 to 22) are created by dividing the information, and information indicating the division order is added to the divided data.

For example, the order 201 of the divided data 20 is “1”, the order 211 of the divided data 21 is “2”, and the like.
Further, it is assumed that a code indicating that it is the last divided data is included in the order 221 of the last divided data 22. For example, “END”.

<Operation>
Hereinafter, the operation of the above-described image reading system will be described with reference to FIG.

FIG. 3 is a flowchart showing processing of the mobile phone 1000 and the mobile phone 2000.
First, the user of the mobile phone 1000 that displays the QR code designates the QR code to be displayed and instructs the display. For the designation of the QR code, for example, a list of QR codes stored in the QR code storage unit 1400 is displayed on the display 1710 and selected with the cursor.

The operation unit 1100 receives designation of a QR code to be displayed and notifies the control unit 1200 (step S100).
The control unit 1200 that has received the notification requests the display control unit 1300 to display the designated QR code, and requests the audio detection unit 1600 to detect the shutter sound.
Upon receiving the QR code display request, the display control unit 1300 reads the first QR code of the corresponding QR code from the QR code storage unit 1400 and makes a display request to the display unit 1700.

Upon receiving the display request, the display unit 1700 displays the first QR code on the display (step S110).
On the other hand, in mobile phone 2000 on the QR code reading side, the user gives an instruction to read the QR code. For example, an instruction is given by selecting “QR code reading” from the menu.
The operation unit 2100 notifies the control unit 2200 that there has been a QR code reading instruction (step S200), and the control unit 2200 that has received the notification requests the imaging unit 2600 to capture a QR code.

The imaging unit 2600 requested to capture the QR code captures the image 4000 and sends it to the image comparison unit 2300 when it is confirmed that the captured image is a QR code (step S210).
At the same time, the sound source unit 2500 is instructed to emit a shutter sound, and the sound source unit 2500 receiving the instruction generates a shutter sound 3000 (step S220).

The image comparison unit 2300 that has received the captured QR code image from the imaging unit 2600 performs reverse conversion to create divided data, is it the same as the divided data that was captured immediately before and stored in the image storage unit 2400? It is determined whether or not (step S230).
If they are the same (step S230: YES), this is notified to the control unit 2200, and the control unit 2200 requests the imaging unit 2600 to capture a QR code (step S210). That is, since the QR code read now is the same as the QR code read immediately before, it is not saved.

If the QR codes are different (step S230: NO), the image comparison unit 2300 stores the divided data of the currently captured QR code in the image storage unit 2400 (step S240).
Further, the image comparison unit 2300 determines whether or not the currently captured QR code is the last QR code, and notifies the control unit 2200 to that effect. This determination is determined to be the last when the order 221 of the divided data is “END”.

The control unit 2200 that is notified of the fact that it is the last QR code (step S250: None) performs a process of ending the QR code reading process. In this end process, the stored divided data are connected to form character data.
Further, the control unit 2200 that is notified that it is not the last QR code (step S250: yes) requests the imaging unit 2600 to capture the QR code (step S210).

On the other hand, in the mobile phone 1000 on the QR code display side, the voice detection unit 1600 requested to detect the shutter sound from the control unit 1200 waits for the sound to be heard outside. Is compared with the shutter sound stored in the shutter sound storage unit 1500, and waits until the same sound is picked up (step S120: NO).
If the picked-up sound and the stored shutter sound are the same (step S120: YES), the control unit 1200 is notified accordingly.

Upon receiving the notification, the control unit 1200 requests the display control unit 1300 to display the next QR code.
Upon receiving the request, the display control unit 1300 reads the next QR code from the QR code storage unit and makes a display request to the display unit 1700 (step S140: present).
If there is no QR code to be read, that is, up to the last QR code is displayed (step S140: No), the fact is returned to the control unit 1200, and the control unit 1200 ends the QR code display process. I do.
