Description

Information processing apparatus, information processing method, and computer-readable recording medium storing program

The present invention relates to an information processing apparatus, an information processing method, and a computer-readable recording medium on which a program is recorded.

In recent years, information processing apparatuses have adopted a multitasking system and can perform a plurality of processes in parallel. In a multitasking system, multiple application programs can be executed, and even if the user is not currently operating or viewing an application program, processing of the application program is continued in the background. It is possible to keep.

The operation state of the information processing apparatus generally has a plurality of stages. Typical operating states include the state in which the application program is being operated or the normal mode in which the application program can be operated, the screen drawing process and backlight lighting are turned off, and the execution status of the application program can be visually confirmed. There are a sleep mode, which is a difficult state, and a shutdown mode, which does not accept most operations for application programs.

In the multitasking system, the application program that was being executed before the transition to the sleep mode is continuously executed even during the sleep mode, so that power continues to be consumed. The more application programs that are being executed, the greater the power consumption of the information processing apparatus. Therefore, in recent years, various techniques for suppressing power consumption have been proposed. For example, Patent Document 1 discloses a technique for stopping the execution of an application program based on a flag indicating whether or not to stop when a casing of a mobile phone is closed.

(1. Hardware configuration of portable communication device)
The information processing apparatus according to the present embodiment is typically realized by the portable communication apparatus 1 shown in FIG. FIG. 2A shows an external view of the portable communication device 1. Hereinafter, the hardware configuration of the portable communication device 1 will be described.

As shown in FIG. 1, the portable communication device 1 includes a CPU (Central Processing Unit) 10, a ROM (Read Only Memory) 11, a RAM (Random Access Memory) 12, a wireless communication unit 13, and an image processing unit 14. A voice processing unit 15, a display 16, operation keys 17, a touch panel 18, a camera 19, a speaker 20, a microphone 21, and a power supply unit 22.

The CPU 10 controls the operation of the entire portable communication device 1 and is connected to each component to exchange control signals and data. For example, the CPU 10 reads a program and data stored in the ROM 11 and executes predetermined processing. Further, since the CPU 10 includes a counter (not shown) inside, the timing for performing the processing is achieved.

The ROM 11 stores an operating system program and various data necessary for operation control of the entire portable communication device 1.

The RAM 12 is for temporarily storing data and programs, and stores data necessary for the CPU 10 to execute various processes and image information data processed by the image processing unit 14.

The wireless communication unit 13 is a unit that performs wireless communication with a wireless communication unit of another portable communication device, and transmits and receives predetermined data via an antenna (not shown) (such as a built-in antenna). The wireless communication unit 13 can also perform wireless LAN communication with a predetermined access point. The wireless communication unit 13 is given a unique MAC (Media Access Control) address.

The image processing unit 14 processes the data read from the ROM 11, the image data captured by the camera 19, or the data processed by the CPU 10, and stores the processed data in the RAM 12.

The audio processing unit 15 converts the audio data read from the ROM 11 into an analog audio signal, and outputs the analog audio signal from the speaker 20 or the headphones connected to the portable communication device 1. In addition, the sound processing unit 15 converts the sound input to the microphone 21 into a digital sound signal and stores the digital sound signal in the RAM 12.

As shown in FIG. 2B, the display 16 includes a display device 16a such as an LCD (Liquid Crystal Display), a backlight (light source) 16b disposed on the rear surface of the display device 16a, and a protective glass disposed on the front surface of the display device 16a. 16c. The display 16 is controlled by the image processing unit 14 and appropriately displays an image indicated by the data stored in the RAM 12.

The operation key 17 is composed of button-

type operation keys

17a, 17b, 17c (FIG. 2A) arranged in the portable communication device 1, and receives a predetermined instruction input according to a user operation. The operation key 17 includes a button (not shown) for adjusting the volume arranged on the side surface of the casing of the portable communication device 1.

The touch panel 18 is arranged so as to be superimposed on the front surface of the display 16 (more precisely, the protective glass 16c), and accepts an input by contact of a user's finger or touch pen. The touch panel 18 is made of a transparent member. For this reason, the user can perform a touch operation on the touch panel 18 while visually recognizing the display on the display 16 through the touch panel 18.

The camera 19 shoots a space or the like according to a user instruction and converts the shot video into an electric signal. The camera 19 is composed of, for example, a CMOS (Complimentary MOS) sensor or the like.

The speaker 20 outputs a predetermined sound according to the audio signal amplified by the audio processing unit 15.

The microphone 21 receives an analog signal such as a user's voice, and the received signal is processed by the voice processing unit 15 such as mixing.

The power supply unit 22 starts or stops power supply to each component according to a control signal from the CPU 10. After the power supply is started, the power supply unit 22 can reduce the supplied power to an arbitrary level by a further control signal from the CPU 10.

The information processing apparatus according to the present embodiment is realized on the typical portable communication apparatus 1 described above, but can also be realized on a general computer, a tablet computer, or a game apparatus. These embodiments are also included in the scope of the present invention.

(2. Functional configuration of portable communication device)
Hereinafter, the functional configuration of the portable communication device 1 will be described in association with the hardware configuration.
As shown in FIG. 3, the portable communication device 1 functionally includes a setting unit 101, an execution unit 102, a display control unit 103, and a reception unit 104.

The portable communication device 1 is set to a normal mode or a sleep mode as an operation mode.

The normal mode is a state in which an application program is executed in the portable communication device 1 and an image indicating the execution state is displayed on the display 16. On the other hand, the sleep mode is a state in which the power consumption is lower than that in the normal mode. For example, the application program is executed in the portable communication device 1, but no power is supplied to the display 16, and nothing is displayed on the screen. This is a state where no image is displayed, or a state where the supplied power is reduced and an image or the like is displayed dimly on the screen. Thereby, in the sleep mode, power consumption of the portable communication device 1 is saved, and power saving is achieved.

Hereinafter, the setting of the sleep mode by the user's operation is referred to as “manual sleep mode”. On the other hand, when the portable communication device 1 does not accept any operation from the user and a predetermined time (hereinafter referred to as “first predetermined time”) has elapsed, the sleep mode is automatically set. This is called “automatic sleep mode”. In the present embodiment, when the manual sleep mode is set, a list of running application programs is presented.

The setting unit 101 sets a normal mode or a sleep mode based on a setting instruction received by the receiving unit 104 described later.

For example, let us assume that the web browser 30 is activated and the web browser 30 is displayed on the display 16 as shown in FIG. 2A. Moreover, although the web browser 30 is activated, the supply of power from the power supply unit 22 to the display 16 is stopped, and as shown in FIG. 5, the state where nothing is displayed is an example of the sleep mode. . The setting unit 101 switches from the normal mode to the sleep mode or from the sleep mode to the normal mode based on the setting instruction.

In this embodiment, the CPU 10 functions as the setting unit 101.

The execution unit 102 executes a plurality of application programs.

The plurality of application programs are, for example, a web browser 30, e-mail software such as e-mail or short message mail, word processor software, and the like. The execution unit 102 can activate a plurality of application programs, and performs these processes in parallel.

In this embodiment, the CPU 10 functions as the execution unit 102.

When the setting unit 101 sets the normal mode, the display control unit 103 displays an image or the like indicating the execution state of the application program on the screen, and when the setting unit 101 sets the sleep mode, the thumbnail image indicating the application program is displayed. Identification information composed of icons or the like is displayed on the screen.

Here, the execution state of the application program means, for example, a state in which the function of the application program is exhibited.

For example, when the web browser 30 is currently being executed, the web page is displayed when the application program is executed. When the setting unit 101 sets the portable communication device 1 to the normal mode, the display control unit 103 displays a web page on the display 16 as shown in FIG. 2A.

On the other hand, the identification information indicating the application program is, for example, a thumbnail or an icon of the application program.

For example, when the web browser 30 and the mail software are currently activated and the setting unit 101 sets the portable communication device 1 to the sleep mode, the display control unit 103 displays an image indicating the execution state of the application program being executed. Are stopped, and

thumbnails

41, 42, and 43 of images indicating those application programs are displayed on the display 16 as shown in FIG.

Here, the

thumbnails

41, 42, 43 are displayed on the display 16 near the hard key provided in the portable communication device 1. For example, the

thumbnails

41, 42, and 43 are displayed in the vicinity of the

operation keys

17a, 17b, and 17c. The thumbnail 41 is associated with the operation key 17a, the thumbnail 42 is associated with the operation key 17b, and the thumbnail 43 is associated with the operation key 17c. . Alternatively, the thumbnail may be arranged in the vicinity of the volume adjustment button arranged on the side surface of the casing of the portable communication device 1 and associated with the volume adjustment button. Thereby, at the time of transition to the sleep mode, the selection of the

thumbnails

41, 42, and 43 can be accepted by the hard key when there is no reaction even if the finger touches the touch panel 18 due to wearing gloves or the like.

Note that the display control unit 103 can also present a message 40 prompting the user to end the application being executed, as shown in FIG. 4, simultaneously with the display of the

thumbnails

41, 42, and 43.

In FIG. 4, the execution state of the application program is not displayed on the display 16, but the display control unit 103 superimposes the message 40 and the

thumbnails

41, 42, and 43 while displaying the execution state of the application program on the display 16. It may be displayed on the front.

In the present embodiment, the CPU 10, the image processing unit 14, and the display 16 cooperate to function as the display control unit 103.

The accepting unit 104 accepts a setting instruction that specifies the normal mode or the sleep mode.

For example, when the portable communication device 1 is in the normal mode (FIG. 2A), when the user presses the operation key 17a for 3 seconds, the receiving unit 104 receives the press as a setting instruction for shifting to the sleep mode. When the reception unit 104 receives a sleep mode setting instruction, the setting unit 101 sets the portable communication device 1 to the sleep mode.

On the other hand, for example, when the portable communication device 1 is in the sleep mode (FIG. 5), when the user presses the operation key 17a for 3 seconds, the receiving unit 104 receives the press as a setting instruction to shift to the normal mode. When the accepting unit 104 accepts the normal mode setting instruction, the setting unit 101 sets the portable communication device 1 to the normal mode.

Further, when the display control unit 103 displays the identification information of the application program on the screen, the reception unit 104 receives a selection instruction for selecting the identification information.

For example, as shown in FIG. 4,

thumbnails

41, 42, and 43 are displayed on the display 16 as identification information of the application program. When the user touches any of the

thumbnails

41, 42, and 43 with a finger or the like, the contact is made. Is accepted as a selection instruction. Alternatively, when any of the

operation keys

17a, 17b, and 17c is pressed, the press is accepted as a selection instruction.

And the execution part 102 complete | finishes execution of the application program specified by the selection instruction | indication which the said reception part 104 received.

For example, when the user's finger touches the thumbnail 41 or the operation key 17a is pressed, the execution unit 102 ends the execution of the application program (for example, a web browser) indicated by the thumbnail 41.

Also, the accepting unit 104 accepts a collective selection instruction for collectively selecting all of the identification information displayed on the screen.

For example, as shown in FIG. 4, when contact with the message 40 is detected in a state where the

thumbnails

41, 42, and 43 are displayed, the contact is used as a collective selection instruction for selecting the

thumbnails

41, 42, and 43. Accept.

And the execution part 102 complete | finishes execution of each application program which the

thumbnails

41, 42, and 43 show.

The receiving unit 104 does not receive a selection instruction or a batch selection instruction until a predetermined time (hereinafter referred to as “second predetermined time”) has elapsed since the display control unit 103 displayed the identification information on the screen. If it is, it is determined that no identification information has been selected. In this case, the setting unit 101 starts transition to the sleep mode.

In the present embodiment, the CPU 10, the operation key 17, and the touch panel 18 cooperate to function as the receiving unit 104.

(3. Operation of portable communication device of embodiment)
Hereinafter, the operation of the portable communication device 1 of the present embodiment will be described. When the portable communication device 1 is powered on, the process shown in the control flowchart of FIG. 6 is started.

The CPU 10 determines whether or not a user operation by the operation key 17 or the touch panel 18 is detected (step S101). When the CPU 10 determines that an operation has been detected (step S101; Yes), the CPU 10 determines whether or not the operation is a setting instruction. That is, the receiving unit 104 determines whether a setting instruction has been received (step S102). On the other hand, if the CPU 10 determines that no operation is detected (step S101; No), the count of the internal counter is cleared, and the control flow proceeds to step S109. Next, the CPU 10 counts from 0 with an internal counter and determines whether or not the first predetermined time has elapsed (step S109).

For example, when the user touches the touch panel 18 and operates the web browser, the CPU 10 determines that an operation by the touch panel 18 is detected. On the other hand, when the user does not touch the operation key 17 or the touch panel 18 and does not perform any operation, the CPU 10 determines whether or not a first predetermined time (for example, 3 minutes) has elapsed.

When the CPU 10 determines that the first predetermined time has elapsed (step S109; Yes), the CPU 10 shifts the portable communication device 1 to the sleep mode (automatic sleep mode) (step S108). On the other hand, when the CPU 10 determines that the first predetermined time has not elapsed (step S109; No), the control flow returns to step S101.

For example, when the CPU 10 determines that no operation is detected and 3 minutes have elapsed, the CPU 10 shifts to the automatic sleep mode. On the other hand, if the CPU 10 determines that 3 minutes have not elapsed, it determines whether an operation has been detected.

In step S102, when the receiving unit 104 determines that a setting instruction has been received (step S102; Yes), the setting unit 101 determines whether or not the setting instruction is an instruction for specifying a sleep mode (step S103). On the other hand, when the CPU 10 determines that the operation is not a setting instruction, that is, when the receiving unit 104 determines that the setting instruction is not received (step S102; No), the control flow returns to step S101 ("A" in FIG. 6). ”).

For example, when the user presses the operation key 17a for 3 seconds, the receiving unit 104 determines that a setting instruction has been received. On the other hand, when the operation key 17a is not pressed for 3 seconds, the CPU 10 determines whether or not an operation has been continuously detected.

When the setting unit 101 determines that the setting instruction is an instruction to specify the sleep mode (step S103; Yes), the display control unit 103 determines whether there is an application program being executed (step S104). On the other hand, when the setting unit 101 determines that the setting instruction is not an instruction to specify the sleep mode (step S103; No), the setting unit 101 sets the portable communication device 1 to the normal mode (step S111). Then, the control flow returns to step S101 (indicated by “A” in FIG. 6).

For example, when the operation key 17a is pressed for 3 seconds in the state set to the normal mode, the setting unit 101 determines that the instruction is for designating the sleep mode. Then, the display control unit 103 determines whether there is an application program being executed. On the other hand, when the operation key 17a is pressed for 3 seconds while the sleep mode is set, the setting unit 101 determines that the instruction is for designating the normal mode. In this case, to set the normal mode, the setting unit 101 supplies power to the display 16 of the display control unit 103, for example, and shifts the portable communication device 1 from the sleep mode to the normal mode. That is, the portable communication device 1 is shifted from the state of FIG. 5 to the state of FIG. 2A.

When the display control unit 103 determines that there is an application program being executed (step S104; Yes), the display control unit 103 displays a thumbnail of the application program on the screen as identification information of the application program (step S105). On the other hand, when the display control unit 103 determines that there is no application program being executed (step S104; No), the setting unit 101 sets the portable communication device 1 to the sleep mode (step S108). Then, the control flow returns to step S101 (indicated by “A” in FIG. 6).

For example, when a sleep mode setting instruction is issued while the web browser 30, mail software, and word processing software are activated, the display control unit 103 is executing the web browser 30, mail software, and word processing software. Judge. Then, as shown in FIG. 4, the display control unit 103 displays thumbnails 41, 42, and 43 including images indicating these application programs on the display 16. On the other hand, when no application program is executed when the sleep mode setting instruction is given, the setting unit 101 shifts the portable communication device 1 to the sleep mode. Stop supplying.

When the identification information is displayed on the screen by the display control unit 103, the receiving unit 104 determines whether or not a selection instruction for selecting the identification information has been received (step S106). When the reception unit 104 determines that a selection instruction has been received (step S106; Yes), the reception unit 104 outputs the selection instruction to the setting unit 101. The setting unit 101 instructs the execution unit 102 to start the end process of the application program specified by the selection instruction, and the execution unit 102 starts the end process (step S107). When the execution unit 102 starts execution of the selected application program, the setting unit 101 sets the portable communication device 1 to the sleep mode (step S108). On the other hand, when the reception unit 104 determines that the selection instruction has not been received (step S106; No), the CPU 10 clears the count of the internal counter, and the control flow proceeds to step S109. Next, the CPU 10 counts from 0 with an internal counter, and the CPU 10 determines whether or not a second predetermined time has elapsed since the identification information was displayed on the screen (step S110).

For example, if contact with any of the

thumbnails

41, 42, and 43 displayed on the display 16 is detected, the reception unit 104 determines that a selection instruction has been received, and the execution unit 102 determines that the contacted thumbnail 41, The execution of the application programs corresponding to 42 and 43 is terminated. And the setting part 101 stops supply of the electric power to the display 16, for example. On the other hand, when contact and pressing of the operation key 17 are not detected, the reception unit 104 determines whether or not a second predetermined time (for example, 10 seconds) has elapsed since the

thumbnails

41, 42, and 43 were displayed on the display 16. To do.

When the reception unit 104 determines that a predetermined time has elapsed since the identification information is displayed on the screen (step S110; Yes), the execution unit 102 does not start the application program termination process, and the setting unit 101 is not portable. The communication device 1 is set to the sleep mode (step S108). On the other hand, when the reception unit 104 determines that the predetermined time has not elapsed since the identification information is displayed on the screen (step S110; No), the control flow returns to step S106.

In step S108, the setting unit 101 stops the power supply to the display 16 of the display control unit 103 in order to set the portable communication device 1 to the sleep mode. That is, as shown in FIG. 8A, the CPU 10 instructs the power supply unit 22 to stop supplying power to the display 16 (step S801), and the power supply unit 22 stops supplying power (step S802). Thereafter, the control flow returns to step S101.

On the other hand, in step S111, the setting unit 101 supplies power to the display 16 to enter the normal mode as shown in FIG. 8B. That is, the CPU 10 instructs the power supply unit 22 to supply power to the display 16 (step S803), and the power supply unit 22 supplies power (step S804). Thereafter, the control flow returns to step S101.

For example, if 10 seconds have elapsed since the

thumbnails

41, 42, and 43 are displayed on the display 16, the execution of the application program indicated by the

thumbnails

41, 42, and 43 is not terminated. Stop supplying power. On the other hand, when 10 seconds have not elapsed since the

thumbnails

41, 42, and 43 are displayed on the display 16, the receiving unit 104 continues to determine whether or not a selection instruction has been received.

In step S102, when the reception unit 104 determines that the user's operation has received a setting instruction (step S102; Yes), the display control unit 103 determines whether there is an application program being executed. It may be. If the display control unit 103 determines that there is an application program being executed, the display program displays the identification information (

thumbnail

41, 42, 43) or the area where the message 40 is displayed (flashes), and the application program being executed is displayed. If it is determined that there is no image, the entire screen may be turned off.

With this configuration, when a setting instruction is accepted, the user can determine whether or not to perform any operation related to step S106.

Further, step S107a shown in FIG. 7 can be applied instead of step S107. In step S107a, after the execution unit 102 finishes execution of the selected application program, the control flow returns to step S104, and through steps S104 to S107, execution of another application program is finished. be able to. Thereby, when there are a plurality of running application programs, the user can terminate any number of application programs.

Note that the operations detected by the CPU 10 in step S101 include, for example, an incoming call response operation and a transmission operation.

The incoming call response operation is performed when the user operates the touch panel 18 or the operation key 17 when the wireless communication unit 13 receives a call, mail, short message or the like from another portable communication device 1. It is an operation that responds to. The call operation is an operation for generating a call, mail, short message, or the like to another portable communication device 1 when the user operates the touch panel 18 or the operation key 17.

When the incoming call response operation or the outgoing call operation is detected (step S101: Yes), the CPU 10 determines that the operation is a setting instruction. That is, the reception unit 104 determines that a setting instruction by an incoming call response operation or a transmission operation has been received (step S102: Yes).

The reception unit 104 inputs such a setting instruction to the setting unit 101, and the setting unit 101 determines that the setting instruction specifies the sleep mode (step S103: Yes). Thereafter, the control flow proceeds to step S104. The processing after step S104 performs the same processing as that described above.

According to the present embodiment, at the time of shifting to the sleep mode, the user can selectively continue execution of the application program or perform end processing. Thereby, power consumption can be suppressed while considering user convenience. In addition, an application program being executed at a specific stage of the information processing apparatus, that is, at the time of transition to the sleep mode, is presented. As a result, it is possible to reduce the burden of having to check whether the application program is always being executed in order to reduce power consumption. In addition, it is possible to make it difficult to cause a situation where power is consumed without completing execution of unnecessary application programs.

In this embodiment, the application program identification information is displayed on the screen when shifting to the manual sleep mode. However, the present invention is not limited to this. For example, the identification information of the application program may be displayed on the screen when shifting to the automatic sleep mode. Thereby, even when the mode automatically shifts to the sleep mode, the user can select an application program to be ended as appropriate.

In this embodiment, the thumbnail display position is in the vicinity of the hard key, but is not limited thereto. For example, the identification information of all application programs being executed may be displayed from the upper left of the screen.

The central part that performs processing for the information processing apparatus including the setting unit 101, the execution unit 102, and the like can be realized by using a normal computer system without using a dedicated system. For example, a computer program for executing the above operation is stored and distributed on a computer-readable recording medium (flexible disk, CD-ROM, DVD-ROM, etc.), and the computer program is installed in the computer. Thus, an information processing apparatus that executes the above-described processing may be configured. Alternatively, the computer program may be stored in a storage device included in a server device on a communication network such as the Internet, and the information processing device may be configured by being downloaded by a normal computer system.

Further, when the functions of the information processing apparatus are realized by sharing of an OS (operating system) and an application program, or by cooperation between the OS and the application program, only the application program part is stored in a recording medium or a storage device. May be.

Also, it is possible to superimpose a computer program on a carrier wave and distribute it via a communication network. For example, the computer program may be posted on a bulletin board (BBS: Bulletin Board System) on a communication network, and the computer program may be distributed via the network. The computer program may be started and executed in the same manner as other application programs under the control of the OS, so that the above-described processing may be executed.
