Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and a device for acquiring information from a screen of an image display device such as a mobile phone, a notebook computer, a PDA without a communication function, and information acquired from a screen of an image display device such as a mobile phone. The present invention relates to a communication system that utilizes a communication method.
[0002]
In this specification, the term "mobile phone" includes a PHS and the like in addition to a mobile phone in a narrow sense, and also includes a PDA and the like having a wireless communication function.
Hereinafter, a mobile phone will be described as an example.
[0003]
[Prior art]
Today, with the development of telecommunications networks, such as telephones, advertising and sales of goods to be sold and services to be provided, and other surveys, etc. Activities and questionnaire surveys are also increasing.
[0004]
For such direct advertisements and questionnaire surveys, for example, according to the roster or list of the purchase target or the survey target obtained, a call is made to a large number of people, or a telephone having an area code or the like of the survey target area. Of the numbers, calls are made sequentially to the phone numbers selected at random, and if there is a response on the called phone, advertisements, sales, questionnaire surveys, etc. may be performed on those who responded. Many.
[0005]
Conventionally, such advertisements / sales, questionnaire surveys, etc. have been carried out by successively making telephone calls to telephone numbers listed in printed lists and lists, etc. In recent years, for example, in recent years, it has been possible to make a database of rosters and lists of callers, and to make a call to a telephone number stored in this database via a computer terminal such as a personal computer. Communication systems have been developed that can be configured to do so.
[0006]
As an example of such a system, there is, for example, a "telephone sales support system" disclosed in Japanese Patent Application Laid-Open No. 2001-245051.
[0007]
This telephone sales support system is configured so that a telephone call can be made using a terminal device equipped with a headset or the like connected to a public line network, and an operator operates a customer list stored in a database. During the operation, the data called by the terminal is displayed on the screen of the terminal, and the operator directly operates a push button or the like of the telephone by, for example, instructing the start of dialing for a predetermined number by clicking a mouse. There is a system configured so that a computer terminal can efficiently make a call via a telephone line connected to the terminal without using the computer terminal.
[0008]
[Problems to be solved by the invention]
Due to the spread of mobile phones, there are many cases where the above-mentioned advertisements, sales calls, and telephone calls for questionnaire surveys are made to mobile phones.
[0009]
In this case, the calling fee is set lower when calling between mobile phones than when calling from a general subscriber phone to a mobile phone. Telephones are advantageous in terms of call charges. Then, in order to reduce the trouble of directly operating the mobile phone by the operator making the call, the communication system having the same configuration as that of the above-described communication system is connected by connecting the mobile phone instead of the telephone line connected to the computer terminal. It can be formed using a telephone.
[0010]
By the way, in the communication system disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2001-245051, since the dial start and the line disconnection instruction to the computer terminal are all performed by the operator on the screen, for example, If the answering machine is away and there is no answer at the called telephone, the operator listens to a predetermined number of ring back tones (so-called "ringing tone"), determines that the customer target of this number is away, and disconnects the line. The operation is performed, and dialing is sequentially performed by selecting the start of dialing for the next customer target displayed on the screen. However, if all of these determinations are to be performed by the operator, the burden on the operator becomes enormous.
[0011]
Therefore, for example, if the above-mentioned computer terminal does not respond to the called telephone during a set timing (for example, reception of a ringback tone for a predetermined time or a set number of times, etc.), the called side will It may be possible to reduce the burden on the operator by disconnecting the line and making a call to the next target person's number in sequence, but the called telephone went on-hook. , That is, information indicating that a line has been established between the calling mobile phone and the called phone is not output via the serial pin of the mobile phone, so that the above-described determination is made by the computer. It cannot be done automatically at the terminal.
[0012]
However, as described above, the fact that a line has been established with the called telephone is not output as data from the serial pin, but at the same time as this line is established, the screen of the image display device such as a mobile phone is displayed. Above, it can be confirmed by the appearance of a talk time counter.
[0013]
As described above, in a mobile phone, although information cannot be obtained as data from a serial pin, there is a large amount of information obtained from an image displayed on a screen. If it is possible to acquire and use the information, it supplements the information acquired through the serial pin, or uses this information together with the information acquired through the serial pin to control various devices using a mobile phone. It is also possible to perform various complicated controls that could not be performed conventionally.
[0014]
Accordingly, a first object of the present invention is to provide a method and an apparatus for acquiring information displayed on a screen of an image display device such as a mobile phone in a state in which it can be used in another device or the like in the form of an electric signal or the like. The purpose is to.

[0030]
In the present embodiment, the light amount adjusting means 5 automatically adjusts the light amount emitted from the light source 22 based on the detection signal of the optical sensor 21, and is constituted by, for example, a servo amplifier.
[0031]
In response to the input signal or the like, the servo amplifier feeds back the detection signal of the optical sensor 21 and inputs the control signal obtained based on the detection signal of the optical sensor 21. The amount of light emitted from the light source 22 by changing the input to the light source 22 and the amount of light received by the optical sensor 21 are balanced so that the image detection capability of the image detection unit 2 is optimally exhibited. ing.
[0032]
Thus, by providing the light amount adjusting means 5 including a servo amplifier or the like, the light amount emitted from the light source 22 is automatically controlled only by attaching the image detection unit 2 to the screen 11 of the mobile phone 10. , Its adjustment is easy.
[0033]
1-3. Central processing unit
When the central processing unit 4 determines that the signal from the optical sensor 21 indicates a change in a predetermined image, for example, the appearance of the counter 12 indicating the talk time on the screen of an image display device such as a mobile phone. , And outputs the result as an electrical signal.
[0034]
When the image detection device 1 includes the light amount adjusting unit 5 as described above, the light amount adjusting unit 5 is controlled based on a signal from the optical sensor 21 to adjust the light amount emitted from the light source 22.
[0035]
In the present embodiment, a so-called “microprocessor (MPU)” in which an arithmetic unit, a register, a decoder, a controller, a program counter, and the like are incorporated in an LSI is used as the central processing unit 4.
[0036]
When the detection signal output from the optical sensor 21 is converted into a digital signal in the A / D converter 3 and then input to the MPU 4, the MPU 4 controls the light amount adjusting means 5 according to a program stored in advance. The input to the light source 22 is adjusted so that the amount of light emitted from the light source 22 becomes optimal.
[0037]
Further, the MPU 4 determines which state before and after the change of the image displayed on the screen 11 of the mobile phone 10 is indicated by the electric signal input according to the program stored in advance, If it is determined that the change in the signal is due to a change in the image indicating the information to be acquired, a signal according to the result of this determination is output.
[0038]
1-4. Description of operation
Using the image detecting device 1 of the present invention configured as described above, a line between the mobile phone 10 on which the image detecting device 1 of the present invention is attached and the called telephone called from the mobile phone 10 is established. An example will be described in which information that the establishment has been obtained is obtained from a change in the image displayed on the screen 11 of the mobile phone 10.
[0039]
First, the cover 23 constituting the image detection unit 2 of the image detection device 1 of the present invention is attached to the mobile phone 10 so that the cover 23 covers the screen 11 of the mobile phone 10. The sensor 21 is mounted facing the position on the screen 11 where the counter 12 indicating the talk time is displayed.
[0040]
When a telephone number is input to the mobile phone 10 in this state, the screen 11 of the mobile phone 10 changes from the standby screen shown in FIG. 3A to that shown in FIG. The dial entered in changes to the screen displayed with characters.
[0041]
When dialing is started, a call is made to this number, and a ringback tone is output from the speaker of the mobile phone 10.
[0042]
When the called telephone that is being called goes on-hook and a line is established with the called telephone, the counting of the call charge starts from this time, and the line 11 is displayed on the screen 11 of the transmitting mobile phone 10. The display of the counter 12 that counts the time from the establishment appears (FIG. 3C).
[0043]
Since the light source 22 and the optical sensor 21 described above are arranged at a position on the screen 11 where the counter 12 for counting the call time is displayed, the counter is displayed on the screen 11 of the mobile phone 10. When 12 is displayed, the appearance of this display changes the reflectance at that position on the screen 11, and the amount of light received by the optical sensor 21 changes before and after the display.
[0044]
Therefore, the electric signal output from the optical sensor 21 also changes with the change in the amount of received light, and this change is output as a detection signal for detecting a change in the image displayed on the screen.
[0045]
The signal from the optical sensor 21 is introduced into the A / D converter 3 and converted into a digital signal, and then input to the above-mentioned MPU 4. In the MPU 4, is this signal a detection signal that has detected the appearance of the counter 12? It is determined whether or not.
[0046]
This determination is made by comparing with a predetermined numerical value set by a simulation or the like, a numerical value sampled when the counter 12 appears, and the like, and thus the signal from the optical sensor 21 indicates the appearance of the counter 12. If the MPU 4 determines that the signal is data indicating that a line between the calling mobile phone and the called telephone has been established, the MPU 4 sends the result of the determination to, for example, various devices using this information by a predetermined signal. (For example, a control signal).
[0047]
Therefore, for example, even if the screen 11 of the mobile phone 10 changes from a standby screen to a screen displaying a telephone number (FIG. 3A to FIG. 3B) as shown in FIG. 21 detects this change in the image as a change in the amount of received light, but as described above, does the MPU 4 detect the appearance of the counter 12 based on a comparison result with data obtained by simulation or sampling? Since the determination is made, the output from the image detection device 1 is accurate.
[0048]
The MPU 4 outputs a control signal for controlling the amount of light emitted from the light source 22 to the above-described light amount control unit 5 based on the digitally converted signal from the optical sensor 21. The light amount control unit 5 adjusts the light irradiation amount of the light source 22 to maintain a state in which the detection capability of the optical sensor 21 is optimally exhibited.
[0049]
2. Application example of image detection device
An example of using the image detection device 1 of the present invention configured as described above will be described below.
[0050]
2-1. Communications system
4 to 6 show an example in which the above-described image detection device 1 is used in a communication system 6 using a computer terminal 60. The communication system 6 includes a computer terminal 60 and a head connected to the computer terminal 60. The headset 61 was attached by operating the above-mentioned mobile phone 10 via the computer terminal 60, comprising the communication means such as the set 61 and the mobile phone 10 having its serial pin connected to the computer terminal 60. It is configured so that the operator can talk with the user of the receiving-side telephone which has established a connection with the mobile telephone 10.
[0051]
The computer terminal 60 includes devices necessary for connecting the mobile phone 10, such as a modem 80 for the mobile phone and an NCU (Network Control Unit) 90 for performing operations such as on-hook, off-hook, and dialing of the mobile phone 10. The serial pin of the mobile phone 10 is connected to the computer terminal 60 via these devices.
[0052]
The modem 80 and the NCU 90 may be housed in a case of the computer terminal 60, for example, and may be formed integrally with the computer terminal 60. However, in the embodiment shown in FIG. An example in which the modem 80 and the NCU 90 are arranged outside the case of the computer terminal 60 is shown.
[0053]
Further, in the example shown in FIG. 4, the modem 80 and the NCU 90 are shown as being separate from each other, but the NCU 90 may be built in the modem 80.
[0054]
The communication system 6 further includes the image detection device 1 for detecting the appearance of the counter 12 described in the above embodiment in addition to the above configuration. Attached on the screen 11 of the mobile phone 10 connected to the terminal 60, a signal output from the MPU 4 can be input to the NCU 90.
[0055]
The signal input from the image detection device 1 to the NCU 90 may be performed by wire, but the data may be transmitted wirelessly. In this case, a necessary wireless transmission / reception unit is provided between the MPU 4 and the NCU 90. .
[0056]
In the configuration of the communication system 6 configured as described above, the communication system 6 is configured to sequentially dial, for example, a plurality of telephone numbers created by a random combination in accordance with a program stored in the computer terminal 60. For example, when the mobile phone instructs the mobile phone to dial one of the telephone numbers created as an example, and the counter 12 does not appear on the screen 11 of the mobile phone 10 within a predetermined time or during a predetermined number of calls, the mobile phone 10 is off-hook, dialing is started for the next telephone number, and the above-described operation is repeated to perform, for example, direct advertisement for an unspecified number of people who own mobile phones. It is configured as a communication system used in such a case.
[0057]
In order to realize the above-mentioned operation, the computer terminal 60 constituting the communication system 6 executes a program stored in the memory, and generates a mobile phone number by a combination of random numbers. A serial pin of the telephone 10 and a signal from the MPU 4 in the image detecting device 1 are received via the NCU 90 or the modem 80, and the NCU 90 is controlled in accordance with the received signal to control the on-hook / off-hook of the mobile telephone 10 and the number generation means. Control means 71 for performing an operation such as dialing for the number generated in step (1).
[0058]
The operation of the communication system 6 configured as described above will be described with reference to FIG. 6. First, one of the telephone numbers generated by the number generating means 72 by the control means 71 is output to the NCU 90, and When dialing is instructed, NCU 90 opens a line using mobile phone 10 as an on-hook and starts dialing a telephone number entered using mobile phone 10.
[0059]
When the dialing of the input number is performed, a ringback tone (a so-called “ringing tone”) is output from the serial pin of the mobile phone 10 to indicate that the called mobile phone is ringing, and the NCU 90 and the modem 80 are transmitted. The control unit 71 receives this via the control unit 71.
[0060]
For example, if the image detection device 1 does not detect the appearance of the counter 12 within a certain period of time after receiving a dial command or during reception of a preset number of ringback tones, the control unit 71 Determines that the mobile phone 10 is in a state in which it cannot respond, and instructs the NCU 90 to off-hook the mobile phone 10. Then, it instructs NCU 90 to dial the next telephone number generated by number generating means 72, and the above-described operation is repeated.
[0061]
On the other hand, if the image detection device 1 detects the appearance of the counter 12 within the set time or during the reception of the set number of ringback tones, the control unit 71 maintains the on-hook state, for example, the line by the operator. Until the disconnection instruction, the reception of the busy tone from the serial pin of the mobile phone 10, or the disappearance of the counter 12 by the image detection device 1, the state in which the conversation by the operator is possible is maintained.
[0062]
When the optical sensor 21 is used as the detection means as described above, the optical sensor 21 displays the number input from the standby screen by inputting a telephone number to the mobile phone 10 as described above, for example. Although the change of the image accompanying the change to the screen to be performed is also detected, as described above, when the MPU 4 outputs to the NCU 90 according to the determination as to whether or not this signal is the signal indicating the appearance of the counter 12, This signal may be used directly as a trigger for the operation of the control means 71. Alternatively, for example, a configuration may be adopted in which all changes on the screen 11 are detected and output to the NCU 90 side. For example, the control unit 71 determines whether the information output through the serial pin (for example, the relationship with the reception timing of the dial tone or the ringback tone) ) In connection with, and decide which of these signals is information indicating the occurrence of a counter 12, it may be configured to control the respective units based on the determination result.
[0063]
During the communication with the called telephones as described above, after the on-hook of the mobile phone 10 is maintained, for example, an instruction to disconnect the line by the operator as described above, reception of a busy tone from the serial pin of the mobile phone 10, or The control means 71 sets the mobile phone to off-hook according to conditions such as the detection of the disappearance of the display of the counter 12 by the image detection device 1 described above.
[0064]
After that, the control means 71 outputs the telephone number to be dialed next among the telephone numbers generated by the number generating means 72 to the NCU 90, and in accordance with this instruction, the NCU 90 dials the received mobile telephone number, and Repeat the above steps.
[0065]
In the communication system described above, a call is made to a telephone number randomly generated in the computer terminal 60. For example, a telephone disclosed in Japanese Patent Application Laid-Open No. As in a sales support system, a telephone number extracted according to predetermined conditions from data stored in a database or the like may be sequentially dialed, and the configuration is limited to the above-described example. is not.
[0066]
3. Other usage examples (remote monitoring system)
