ELECTRONIC DEVICE, OPERATION CONTROL METHOD, AND PROGRAM

Abstract

When a user performs a closing operation of a touch screen slide type cellular phone and the closing operation is performed in a state where the touch screen is contacted, a CPU continuously puts a display and the touch screen into an ON state, which continuously allows touch operations on the touch screen. In contrast, when the closing operation is made without the user's physical contact with the touch screen, the CPU continuously puts the display and the touch screen into an OFF state. Accordingly, reduction of wasteful power consumption can be easily realized without impairing the usability for a user and without requiring complicated control.

Description

TECHNICAL FIELD

The present invention relates to an electronic device, an operation control method and a program.

BACKGROUND ART

In recent years, as is described in Patent Documents 1 and 2, portable terminal apparatuses which include a display equipped with a touch screen have been widespread. A user touches the touch screen on the display so as to input numerical numbers and characters and instructs the operations, in addition to key operations or in place of the key operations.

FIGS. 7( a) and 7(b) are perspective views of the external configuration of a slide type cellular phone. In the diagrams, a reference number 1 represents a touch screen, and a reference number 2 represents a display, and a reference number 3 represents a key operating section. In FIGS. 7(a) and 7(b), the touch screen 1 and the display 2 are disposed at the same position relative to each other. Similarly, a backlight (not illustrated) is provided in the display 2. As is described in FIG. 7(a), the display 2 is slidable in the direction of an arrow. When an open operation is carried out, and the display 2 is put into an open state, an input operation by means of the key operating section 3 is available. Similarly, as is illustrated in FIG. 7(b), when a closing operation is carried out, and the display 2 is covered with the key operating section 3 and put into a closed state, a touch operation by means of the touch screen 1 is available.

Incidentally, with respect to the portable terminal apparatus which includes the touch screen 1, and which includes the slide type cellular phone above, the touch operation on the touch screen 1 is made while the display 2 is displayed, so it is important how the power consumption is suppressed.

FIG. 8 is a flowchart illustrating the operation of the slide type cellular phone. When a user starts using the slide type cellular phone, and the open operation is made, the open state is detected (Step S10), the display 2 (backlight) and the touch screen 1 are turned into ON+ (ON continuation) (Step S12). In this case, the user carries out the operation with the key operating section 3.

Similarly, when the user carries out the closing operation, the closed state is detected (Step S14). In this case, it is judged whether or not a non-operation is made during a period of T1 seconds which are set by the user in advance (Step S16). When any operation is made in the closed state, the display (backlight) and the touch screen 1 are put into ON+ (ON continuation), so that the user operates the slide type cellular phone with the touch screen 1 (Step S18). Then, when the non-operation in the closed state is continued during the period of T1 seconds which are set by the user in advance, the display 2 (backlight) and the touch screen 1 are turned off (Step S20).

SUMMARY OF INVENTION

Problem to be Solved by the Invention

However, in the technology disclosed by the aforementioned Patent Document 1, for example, when the user stops the use of the slide type cellular phone after carrying out the closing operation and puts the slide type cellular phone into a pocket, a bag, and the like, the display 2 (backlight) and the touch screen 1 are turned off after the lapse of the T1 seconds which are set by the user in advance. Accordingly, there is a problem in that power is wastefully consumed during the period of the T1 seconds.

Similarly, when the user sets the aforementioned T1 seconds which are set by the user in advance, to zero second in order to prevent wasteful power consumption, and when the user desires the continuous use of the slide type cellular phone based on the operation of the touch screen 1 after the closing operation, the display 2 (backlight) and the touch screen 1 are immediately turned off. Accordingly, there is a problem in that the usability for the user is substantially deteriorated.

Further, in this case, a certain additional operation is required for the user, so as to turn on the display 2 (backlight) and the touch screen 1 for the purpose of the user's continuous use of the slide type cellular phone. For example, it is conceivable that a side key is pressed, or that the touch screen 1 is brought into contact again. In the case of the latter, only the power source of the touch screen 1 is not immediately turned off, but the power source needs to be continuously turned on for a certain period of time, so that there is a problem in that complicated control is required.

Therefore, it is an object of the present invention to provide an electronic device, an operation control method and a program which can easily realize the reduction of wasteful power consumption without impairing the usability for a user and without requiring complicated control.

DESCRIPTION OF EMBODIMENTS

Hereinafter, the embodiment of the present invention will be described referring to the drawings.

FIG. 1 is a perspective view illustrating the external configuration of a slide type cellular phone of the embodiment of the present invention. The external configuration of the slide type cellular phone of the embodiment of the present invention is the same as that of a slide type cellular phone illustrated in FIG. 7, so its description is omitted, and the same reference numbers are applied. The touch screen 1 may be of a contact detection type which detects direct contact or of a proximity detection type which detects the close proximity of a finger and the like. Similarly, the touch screen 1, a display 2, and a backlight 4 can be separately ON/OFF controlled.

FIG. 2 is a block diagram illustrating the configuration of the slide type cellular phone of the embodiment of the present invention. The same reference numbers are applied for portions corresponding to FIG. 1, and its description is omitted. A reference number 4 represents a backlight which illuminates the display 2. A reference number 5 represents an open-and-close detecting section which detects the opening and closing of the display 2. A reference number 6 represents a CPU which controls the backlight 4 and the open-and-close detecting section 5.

FIG. 3 is a perspective view of the slide type cellular phone in use in an open state according to the embodiment of the present invention. When a user operates the slide type cellular phone in the open state, which is aimed at operating the key operating section 3, the user puts the touch screen 1 into an OFF state in order to reduce wasteful power consumption. Similarly, the user operates the key operating section 3 while watching the display 2, so that the display 2 and the backlight 4 are continuously put into the ON state (hereinafter referred to as “ON+”) during the continuous non-operation in the seconds which are set by the user in advance.

FIG. 4 is a perspective view of the slide type cellular phone in use in a closed state according to the embodiment of the present invention. When the slide type cellular phone is put into the closed state, and the user contacts with the touch screen 1, the touch screen 1, the display 2, and the backlight 4 are turned into ON+. Accordingly, the user can continuously operate the touch screen 1 after the slide type cellular phone is closed.

FIGS. 5( a) and (b) are perspective views in a case where the slide type cellular phone is put into the closed state without the user's physical contact with the touch screen 1. FIG. 5(a) illustrates a state where the user puts his thumb of his left hand to a case portion on the periphery of the display 2 and slides his thumb in the direction of an arrow, so as to put the slide type cellular phone into the closed state. Similarly, FIG. 5(b) illustrates a state where the user holds the slide type cellular phone with his left hand and slides the case on the side of the display 2 with his right hand in the direction of the arrow, so as to put the slide type cellular phone into the closed state, without physical contact with the touch screen 1 (display 2).

In the embodiment of the present invention, as is illustrated in FIGS. 5(a) and (b), in either case where the slide type cellular phone is put into the closed state without the user's physical contact with the touch screen 1, the touch screen 1, the display 2, and the backlight 4 are turned off. Accordingly, when the user stops using the slide type cellular phone, the user can put the slide type cellular phone into a pocket, a bag or the like, without wasteful power consumption after the slide type cellular phone is closed. Incidentally, herein, the touch screen 1, the display 2, and the backlight 4 are turned off, but all are not required to be turned off. However, any one or any combined two, out of the touch screen 1, the display 2, and the backlight 4, may be turned off.

Next, the operation of the aforementioned embodiment will be described.

FIG. 6 is a flowchart to describe the operation of the slide type cellular phone of the embodiment of the present invention. When the user starts using the slide type cellular phone and carries out the open operation, the open-and-close detecting section 5 detects the open state (Step S30). The CPU 6 judges whether or not a power saving mode at the time of the closed state is set to ON (Step S32). Then, when the power saving mode at the time of the closed state is not set to ON, as is the same case with the aforementioned conventional technology, the operations of the Step S12 afterwards, which are illustrated in FIG. 8, are executed (Step S34).

In contrast, when the power saving mode at the time of the closed state is set to ON, the display 2 and the backlight 4 are put into ON+ (Step S36). At this time, the user operates the slide type cellular phone by means of the key operating section 3, without using the touch screen 1 (see FIG. 3). That is, the touch screen 1 is turned off, so that wasteful power consumption can be reduced.

Herein, when the user carries out the closing operation, that is, at a time point when the sliding of the display 2 is started, the open-and-close detecting section 5 detects the closed state (Step S38), and the touch screen 1 is turned into ON+ (Step S40). At this time, the CPU 6 judges whether or not the finger of the user comes in contact with the touch screen (Step S42).

Then, when the finger of the user does not come in contact with the touch screen 1 (Step S42, NO), the display 2 and the backlight 4 are immediately turned off, and the touch screen 1 is also turned off accordingly (Step S44: see FIGS. 5(a) and 5(b). The user stops using the slide type cellular phone and puts the slide type cellular phone into his pocket, a bag or the like. Accordingly, after the user stops using the slide type cellular phone, electric power is not wastefully consumed. Incidentally, herein, the touch screen 1, the display 2, and the backlight 4 are turned off, but all are not required to be turned off. However, any one or any combined two, out of the touch screen 1, the display 2, and the backlight 4, may be turned off.

In contrast, when the finger of the user comes in contact with the touch screen 1 (Step S42, YES), the user continuously operates the slide type cellular phone by means of the touch screen 1 (see FIG. 4). In this time, the display 2, the backlight 4, and the touch screen 1 are put into ON+ (continuation).

In this case, it is judged whether or not the non-operation is continued for the period of T1 seconds which are set by the user in advance (Step S48). When any operation with regards to the touch screen 1 in the closed state is made (Step S48, NO), the display 2, the backlight 4, and the touch screen 1 are put into ON+ (ON continuation), and the user continuously operates the slide type cellular phone by means of the touch screen 1 (Step S50).

In contrast, when a non-operational state with regards to the touch screen 1 in the closed state is continued during the period of T1 seconds which are set by the user in advance (Step S48, YES), the display 2, the backlight 4 and the touch screen 1 are turned off (Step S52). Incidentally, herein, the touch screen 1, the display 2, and the backlight 4 are turned off, but all are not required to be turned off. However, any one or any combined two, out of the touch screen 1, the display 2, and the backlight 4, may be turned off.

According to the aforementioned embodiment of the present invention, when the user carries out the closing operation of a touch screen slide type cellular phone and the closing operation is made in a state where the touch screen 1 is contacted, the display 2, the backlight 4 and the touch screen 1 are continuously put into an ON state, which continuously allows the touch operation on the touch screen 1. In contrast, when the closing operation is made in a state where the touch screen 1 is not contacted, the display 2, the backlight 4 and the touch screen 1 are continuously put into an OFF state.

Accordingly, this properly distinguishes between a case where the touch screen 1 continuously used and a case where the slide type cellular phone is put into a pocket, a bag and the like as it is, without impairing the usability for the user and requiring the complicated control, and the reduction of wasteful power consumption of the touch screen slide type cellular phone can readily be realized.

In the aforementioned embodiment of the present invention, the cellular phones are exemplified. However, the present invention is not limited to the cellular phone and smart phones and can be applied to other devices (for example, game machines, tablet personal computers, and notebook personal computers).

In the aforementioned embodiment of the present invention, ON/OFF control of the touch screen 1, the display 2, and the backlight 4 has been described. There has been known a cellular phone in which its key top is lighted from the back surface of the key operating section 3 in order to carry out the key operation even in the dark. In this case, the backlight of the key operating section 3 may be ON/OFF controlled when the user carries out the open operation or the closing operation of the touch screen slide type cellular phone.

Similarly, in the aforementioned embodiment of the present invention, the slide type cellular phone has been described. However, the present invention is not limited to the slide type cellular phone. The present invention can be applied to a collapsible type, that is, a collapsible type which is made up of a first case including an operating section such as a key, and a second case including a display section such as liquid crystal, and the display section includes a touch screen, and further, the collapsible type has a collapsible shape in which the display section is rotated and externally exposed (also referred to as “rotary biaxial hinge type” which includes two axes, which are a rotation axis to be folded and a rotation axis used for rotating the display section). Similarly, the present invention can be applied to a rotation type which includes the touch screen.

Hereinafter, the features of the present invention will be described.

Part or the entire aforementioned embodiment of the present invention can be described below. However, the present invention is not limited to the description below.
