Abstract

A data processing system (S) is configured so as mutually register transmission destinations between devices performing communication. In addition, the data processing system (S) performs a predetermined communication procedure for communicating predetermined information to transition to a communication connection state establishing a mutual communication connection, and in the communication connection state, performs intermittent periodic communication every predetermined interval, where the communication connection state is maintained while periodic communication is maintained, and the communication connection state is released in a case of the periodic communication being interrupted, and in the state in which the communication connection state is released, controls the allowance of transition to the communication connection state again, according to a change state of contents of the predetermined information sent upon transitioning to the communication connection state, and the presence of a transmission destination recorded.

First claim

What is claimed is:

1. A data processing system comprising a peripheral apparatus which provides a predetermined function and a central apparatus which utilizes the function provided by the peripheral apparatus, wherein the data processing system executes predetermined data processing through the peripheral apparatus and the central apparatus,
wherein the peripheral apparatus comprises:
first communication circuitry which, in a case of not establishing a communication connection with any central apparatus, (i) sends an advertising signal that notifies other apparatuses of its own existence and its own function by way of broadcast communication, (ii) establishes a communication connection with a central apparatus that responds to the advertising signal, and (iii) performs communication control by way of a first communication method that maintains a communication connection by performing communication periodically with the central apparatus having established the communication connection; and
a CPU that executes the predetermined data processing by linking with the central apparatus,
wherein the central apparatus comprises:
first communication circuitry which (i) detects an advertising signal sent by the peripheral apparatus, (ii) establishes a communication connection by way of the first communication method with the peripheral apparatus in a case in which the function indicated by the advertising signal is a desired function, and (iii) performs communication control by way of the first communication method to maintain a communication connection by performing communication periodically with the peripheral apparatus having established the communication connection; and
a CPU which executes the predetermined data processing by linking with the peripheral apparatus,
wherein the first communication circuitry of the peripheral apparatus and the first communication circuitry of the central apparatus maintain a communication connection by performing communication periodically, even in a case in which the peripheral apparatus and the central apparatus are not in a predetermined operation state capable of executing the predetermined data processing,
wherein in the case of not being in the predetermined operation state,
the central apparatus starts an application program, from a state of not running the application program, by receiving predetermined signals via the first communication circuitry from the peripheral apparatus, the application program having a function which causes the peripheral apparatus and the central apparatus to be in the predetermined operation state,
the CPU of the peripheral apparatus and the CPU of the central apparatus cause the peripheral apparatus and the central apparatus to link to each other, and
the CPU of the peripheral apparatus and the CPU of the central apparatus cause execution of the predetermined data processing to start, after causing the transition to the predetermined operation state by operation of the application program,
wherein the peripheral apparatus is an imaging device having an image capture function,
wherein the central apparatus is an information terminal having an image management function, and
wherein the predetermined data processing is processing to send an image captured by the imaging device to the information terminal, and causing the image sent to be managed in the information terminal,
wherein the CPU of the information terminal:
causes an image management program required in execution of the predetermined data processing to transition to an execution stop state of temporarily stopping execution, while maintaining a communication connection by the first communication circuitry,
causes the image management program that is in the execution stop state to transition to an execution state, in a case of receiving a predetermined signal from the imaging device via the first communication circuitry, and
executes processing to receive and manage an image sent from the imaging device, according to the image management program having transitioned to the execution state
wherein the CPU of the information terminal causes the image management program to execute in the background while maintaining a communication connection by the first communication circuitry, and in a case of exceeding an time limit for background execute defined by an operating system and continuously executing the image management program, causes the image management program to transition to an execution stop state, and
wherein the CPU of the imaging device sends a predetermined signal via the first communication circuitry to cause the image management program that is in the execution stop state to transition to the execution state, every time execution of the predetermined data processing is interrupted due to the information terminal causing the image management program to transition to the execution stop state due to a time limit of background execution according to the operating system, and then causes execution of the predetermined data processing that is interrupted to restart.

2. The data processing system according to claim 1 , wherein the CPU of the peripheral apparatus and the CPU of the central apparatus, in a case in which either one of the peripheral apparatus and the central apparatus is not in the predetermined operation state, cause the apparatus not in the predetermined operation state to transition to the predetermined operation state, by transmitting from the apparatus in the predetermined operation state a predetermined signal via the first communication circuitry thereof to the apparatus not in the predetermined operation state.

3. The data processing system according to claim 1 , wherein the CPU of the peripheral apparatus and the CPU of the central apparatus:
cause any peripheral apparatus and any central apparatus to transition to a pairing state that is a state combining with each other;
cause a communication connection to be established by way of the first communication circuitries between the peripheral apparatus and the central apparatus having transitioned to the pairing state; and
execute the predetermined data processing by causing the peripheral apparatus and the central apparatus having transitioned to the pairing state to link.

4. The data processing system according to claim 3 , wherein the CPU of the peripheral apparatus and the CPU of the central apparatus, in a case of establishing a communication connection between the peripheral apparatus and the central apparatus that are not in the pairing state, control the first communication circuitries so as to establish a communication connection under a condition that a user operation for causing the two apparatuses to newly transition to the pairing state has been performed, and in a case of establishing a communication connection between the peripheral apparatus and the central apparatus that are in the pairing state, control the first communication circuitries so as to establish a communication connection automatically without a user operation being performed.

5. The data processing system according to claim 3 , wherein the CPU of the peripheral apparatus and the CPU of the central apparatus, in a case of establishing a communication connection between the peripheral apparatus and the central apparatus, determine whether or not to cause a communication connection to be established by referencing a pairing state of the two apparatuses, and a pairing state of a combination with another peripheral apparatus or another central apparatus.

6. The data processing system according to claim 5 ,
wherein the CPU of the peripheral apparatus controls the first communication circuitry so as to cause a state of a part of the advertising signal to change according to the pairing state, upon sending the advertis
