Description

  The present disclosure relates to a mobile terminal that accepts an input operation by a touch operation, and more particularly, to a technology that improves operability while protecting a touch screen for accepting a touch operation.

  Mobile terminals (for example, smartphones) are becoming more and more popular due to higher performance and lighter weight. In recent years, portable terminals that include a touch screen and accept user input operations are increasing in order to enable human intuitive operations. If the scratch increases on the touch screen as the user uses the mobile terminal, the visibility of the information displayed on the touch screen also deteriorates. Therefore, in order to maintain the operability of the mobile terminal, the user may use a protective sheet (for example, a transparent film) attached to a touch screen.

  For example, Japanese Unexamined Patent Publication No. 2013-175109 (Patent Document 1 below) easily sets an optimum touch panel sensitivity without being affected by the presence or type of a protective sheet in a mobile terminal equipped with a touch panel function. The technology to do is described. Specifically, in the technique of Patent Document 1, when a protective sheet is attached to the touch panel, the touch panel detection signal when the touch panel portion covered by the protective sheet is touched and the protective sheet is covered. It is described that the detection sensitivity of the touch panel is set based on a signal with a detection signal of the touch panel when the touch panel portion exposed is touched.

  In addition, a cover that can be attached to the mobile terminal is provided to protect the mobile terminal from an impact when dropped. The user selects a cover corresponding to the model of the mobile terminal used by the user and attaches the cover to the mobile terminal.

  Various covers are offered to the market by the companies that produce the covers. In particular, when a touch screen is damaged due to a drop of a mobile terminal or the like, the visibility of information displayed on the touch screen deteriorates. There are an increasing number of users who wear covers capable of covering the mobile terminals on mobile terminals. For example, by attaching a book cover type cover to a mobile terminal, the user protects the front and back surfaces of the mobile terminal on which the touch screen of the mobile terminal is placed from a drop impact, etc. Can do.

  Some of these book cover type covers have openings. The opening is overlaid on the touch screen with the cover covering the touch screen. Thereby, even in a state where the cover is covered with the touch screen, the user can check the display content in the opening or perform a touch operation on the opening.

  Hereinafter, the state in which the cover covers the touch screen of the mobile terminal is also referred to as “closed state”. A state where the cover does not cover the touch screen of the portable terminal is also referred to as an “open state”. The area of the touch screen corresponding to the position of the opening in the closed state is also referred to as a “window area”. An area other than the window area in the area of the touch screen of the mobile terminal is also referred to as a “non-window area”.

JP 2013-175109 A

  In the closed state where the cover covers the touch screen of the mobile terminal, the user normally intends to perform a touch operation on the content displayed in the window area corresponding to the opening. However, when the touch screen erroneously detects the touch operation of the user in the non-window area portion other than the opening portion in the closed state of the mobile terminal, an operation unintended by the user is performed on the mobile terminal there is a possibility. Therefore, there is a need for a technique for further improving user operability in the closed state in which the cover having the opening covers the touch screen of the mobile terminal.

  Hereinafter, the present embodiment will be described with reference to the drawings. In the following description, the same parts and components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. Each embodiment and each modified example described below may be selectively combined as appropriate.

<Technology>
First, the technical idea of the technology specifically described in the following embodiment will be described. For example, there is a mobile terminal including a touch screen such as a smartphone. In order to protect the portable terminal from physical impact, dust adhesion, and the like, it is assumed that, for example, a book cover type cover can be attached to the portable terminal so that the surface on which the touch screen is arranged can be covered. Some of these covers have small windows serving as openings. The opening may be provided with a protective member such as a thin plastic surface or a glassy protective sheet. When the cover covers the touch screen of the mobile terminal, the opening is not protected by the cover material. Protect the touch screen from dirt and dust.

  Normally, when this cover with an opening is attached to a mobile terminal, in a closed state where the cover covers the touch screen, information useful for the user is displayed on the opening and can be operated by the user with the touch screen. It is produced with the intention of becoming. However, depending on the material of the cover, even if the cover is attached to the mobile terminal and the touch screen is closed, the touch screen may erroneously detect the user's touch operation in a portion other than the opening, and the user's operation May cause trouble. Also, depending on the material of the protective member provided in the opening, even if the user touches the touch screen at the opening, the touch operation on the touch screen is affected by the thickness of the protective member and the material. There is a possibility that the sensitivity of the user may be lowered, and there is a possibility that the user's operation may be hindered.

  Therefore, in the closed state where the cover having the opening covers the touch screen, the mobile terminal shown in the present embodiment is located at the position of the opening when the cover is attached to the mobile terminal in the range where the touch screen accepts a touch operation. A corresponding fixed range (window region) is stored by setting or the like. When the mobile terminal detects a closed state in which the touch screen is covered with a cover, the sensitivity of the touch operation in the certain range (window region) is higher than that in the other range (non-window region). (For example, the mobile terminal performs settings such as increasing the sensitivity of the touch operation in the window area and decreasing the sensitivity of the touch operation in the non-window area). With this configuration, the mobile terminal can suppress erroneous detection of a user's touch operation in a non-window area (a part other than a small window), and touch via the window area (a small window part). The operability of the operation can be improved.

  Further, when the mobile terminal shown in the present embodiment detects that the cover is opened and the touch screen is not covered with the cover, the touch screen performs the touch operation sensitivity. Return to the entire accepted range.

  The user may perform a touch operation on the entire touch screen after opening the portable terminal (with the cover removed from the touch screen). Therefore, the user sometimes attaches a protective member such as a protective film to the touch screen in order to prevent dust adhesion on the touch screen. In this case, when a book cover type cover is attached to the portable terminal, the user performs a touch operation on the touch screen from above the protective member provided in the opening with the cover attached. Therefore, the mobile terminal according to the present embodiment suppresses malfunctions that are not intended by the user by adjusting the sensitivity of the touch screen according to whether the cover is open or closed. As described above, since erroneous detection of the touch operation in a portion other than the opening (other than the small window) is less likely to occur, the operability of the touch operation through the opening can be further improved.

<First Embodiment>
A mobile terminal according to the first embodiment will be described. The portable terminal sets the sensitivity of the touch screen as a prior setting so that the user can operate the application displayed in the window area.

  (1) The mobile terminal adjusts the sensitivity of the touch operation when a protective member such as a protective sheet for protecting the screen is attached to the touch screen. Specifically, the mobile terminal accepts a user input operation and sets the sensitivity of the touch operation.

  (2) The mobile terminal performs setting of the sensitivity of the touch screen in the window area when the mobile terminal is in a closed state so that the cover having the opening covers the touch screen, for example, according to the input operation of the user . In addition, the mobile terminal sets the sensitivity of the touch operation in the non-window region so that the touch operation to the non-window region that is a range other than the window region out of the range in which the touch screen accepts the touch operation is invalidated. As a result, in the state where the touch screen is covered with the cover, an erroneous operation unintended by the user due to the touch operation on the touch screen is suppressed.

  (3) The touch sensitivity settings of the window area and the non-window area when the portable terminal is in the closed state are stored in the memory.

  With this configuration, when the mobile terminal detects that the mobile terminal is in the closed state, the mobile terminal validates the sensitivity setting for the touch operation in the window area and the non-window area. Thereby, the touch operation on the window area can be accepted with the optimum sensitivity of the touch screen, and the touch operation on the non-window area is invalidated, so that a malfunction that is not intended by the user can be suppressed.

[Window area setting]
With reference to FIG. 1, the outline | summary of the portable terminal 100 according to 1st Embodiment is demonstrated. FIG. 1 is a diagram showing an example of the setting operation of the window area 105A and the sensitivity setting of the touch panel in time series.

  Although FIG. 1 shows a portable terminal 100 as a smartphone, the portable terminal 100 is not limited to a smartphone. For example, the portable terminal 100 may be a portable device including a tablet terminal, a Fablet, a digital camera, an electronic dictionary, a PDA (Personal Digital Assistant), a game machine, or other display unit.

  The mobile terminal 100 includes a display unit 105. A touch panel 106 (see FIG. 4) described later is superimposed on the display unit 105. The display unit 105 and the touch panel 106 constitute a touch screen. The portable terminal 100 detects a user's touch operation on the display unit 105 with the touch panel 106. The user can operate the portable terminal 100 by a touch operation on the display unit 105.

  A cover 200 can be attached to the mobile terminal 100. The cover 200 is provided with an opening 210. As shown in step (A), the cover 200 does not cover the display unit 105 in the open state of the cover 200.

  It is assumed that the cover 200 is closed by the user in step (B). When the cover 200 is closed, the opening 210 of the cover 200 is overlapped with the display unit 105. As a result, the user can perform a touch operation on the display portion corresponding to the opening 210 even when the cover 200 is closed.

  In step (C), the mobile terminal 100 accepts a setting operation for the window area 105 </ b> A within the display area of the display unit 105. In one aspect, the user sets the window area 105A by an operation of tracing the display area in the opening 210 with a finger. In another aspect, the user sets window region 105 </ b> A by performing an operation such as pinch-in or pinch-out on the display region in opening 210. When receiving the setting operation for the window area 105A, the portable terminal 100 stores the position of the window area 105A.

  In step (D), when the cover 200 is closed, the mobile terminal 100 sets the sensitivity of the touch panel 106 in the non-window area 105B other than the window area 105A in the display area of the display unit 105 from the sensitivity of the touch panel in the window area 105A. Also set to lower. For example, the mobile terminal 100 increases the sensitivity of the touch panel 106 in the window region 105A in the closed state as compared with the open state. For example, in the closed state, the mobile terminal 100 sets the sensitivity of the touch panel 106 in the non-window area 105B so that the touch operation is invalid. Even when the cover 200 is closed, the user can check the display contents in the window area 105A and perform a touch operation on the window area 105A.

  After the setting of the window area 105A, the portable terminal 100 lowers the sensitivity of the touch panel 106 in the non-window area 105B to be lower than the sensitivity of the touch panel 106 in the window area 105A every time it detects the closed state of the cover 200. Thus, the user does not need to set the window area 105A again after setting the window area 105A.

  Although FIG. 1 shows an example in which the window area 105A is rectangular, the window area 105A is not limited to a rectangle. For example, the window region 105A may be circular, elliptical, polygonal, or other closed shape. As an operation example for setting the circular window region 105A, the mobile terminal 100 detects a long press operation of one point on the display unit 105, and detects a predetermined range centered on the one point as the window region 105A. .

  1 shows an example in which only one window area 105A is set, the mobile terminal 100 may accept the setting of a plurality of window areas 105A.

[Functional configuration of portable terminal 100]
With reference to FIG. 2, the function of the portable terminal 100 is demonstrated. FIG. 2 is a diagram illustrating an example of a functional configuration of the mobile terminal 100.

  As shown in FIG. 2, the mobile terminal 100 includes a CPU (Central Processing Unit) 102 and a RAM (Random Access Memory) 103 as hardware configurations. The CPU 102 includes a detection unit 150, a reception unit 155, and a sensitivity control unit 160 as functional configurations.

  The detection unit 150 detects the closed state of the cover 200 (see FIG. 1). Various detection methods may be employed as the closed state detection method. As an example, the detection unit 150 detects the closed state of the cover 200 based on an output value from a magnetic sensor 107 described later. More specifically, the mobile terminal 100 and the cover 200 are each provided with a magnet, and the magnets come into contact with each other with the cover 200 closed. The output value of the magnetic sensor 107 changes according to a change in magnetism caused by contact between magnets. The detection unit 150 detects the closed state of the cover 200 when the output value of the magnetic sensor 107 changes by a predetermined amount or more within a certain time.

  The accepting unit 155 accepts a setting operation for the window region 105A (see FIG. 1) based on the detection of the closed state of the cover 200 by the detecting unit 150. The accepting unit 155 stores the set range information 103A of the window area 105A in the RAM 103.

  When the cover 200 is in the closed state, the sensitivity control unit 160 refers to the range information 103A of the window region 105A and identifies the range of the window region 105A and the range of the non-window region 105B (see FIG. 1) in the display unit 105. Then, the sensitivity of the touch panel 106 in the non-window area 105B is made lower than the sensitivity of the touch panel 106 in the window area 105A. Preferably, the sensitivity of the touch panel 106 in the non-window region 105B is invalidated. The sensitivity control unit 160 displays content corresponding to the position and size of the window area 105A in the window area 105A. More specifically, the position and size of the window area and the type of content to be displayed are associated in advance as a table. The display target content includes, for example, a clock and an image. The sensitivity control unit 160 identifies the content associated with the set size and position of the window area 105A, and displays the content in the window area 105A.

  Note that the timing at which the sensitivity control unit 160 changes the settings of the sensitivity of the touch panel 106 in the window region 105A and the sensitivity of the touch panel 106 in the non-window region 105B is not limited to the timing at which the closed state of the cover 200 is detected. For example, at the timing when the power button of the portable terminal 100 is pressed when the cover 200 is closed, the sensitivity control unit 160 relatively increases the sensitivity of the touch panel 106 in the window region 105A in accordance with the range information 103A, and the non-window region. The sensitivity of the 105B touch panel 106 may be relatively low. In addition, at the timing when the touch operation in the window area 105A is detected when the cover 200 is closed, the sensitivity control unit 160 ranges the sensitivity of the touch panel 106 in the window area 105A and the sensitivity of the touch panel 106 in the non-window area 105B. You may set according to the information 103A.

[Hardware configuration of portable terminal 100]
With reference to FIG. 3, an example of a hardware configuration of the mobile terminal 100 will be described. FIG. 3 is a block diagram illustrating a main hardware configuration of the mobile terminal 100. As shown in FIG. 3, the mobile terminal 100 includes a ROM (Read Only Memory) 101, a CPU 102, a RAM 103, a display unit 105, a touch panel 106, a magnetic sensor 107, a network interface 108, and a camera 113. And storage device 120. The touch screen 111 includes a display unit 105 and a touch panel 106.

The ROM 101 stores the operating system of the mobile terminal 100 and the like.
The CPU 102 controls the operation of the mobile terminal 100 by executing various programs such as the operating system of the mobile terminal 100 and the control program 122 of the mobile terminal 100.

  The RAM 103 functions as a working memory and temporarily stores various data necessary for executing the control program 122. The temporarily stored data includes, for example, range information 103A of the window area 105A. The range information 103 </ b> A of the window area 105 </ b> A is read from the storage device 120 or the like when the control program 122 is executed and written to the RAM 103. The storage location of the range information 103A is not limited to the RAM 103. For example, the range information 103 </ b> A may be stored in a communication terminal other than the ROM 101, the storage device 120, and the mobile terminal 100.

  The display unit 105 is overlaid on the touch panel 106. Thereby, the portable terminal 100 can accept a user's touch operation. The touch panel 106 outputs the position of the display unit 105 touched by the user to the CPU 102 as a coordinate value.

  The magnetic sensor 107 is provided in the vicinity of the magnet 107 </ b> A of the mobile terminal 100. The magnetic sensor 107 detects the magnitude of the surrounding magnetic field and outputs the detected magnitude of the magnetic field to the CPU 102. The CPU 102 utilizes the fact that the magnitude of the magnetic field changes when the magnet 220 of the cover 200 approaches the magnet 107 </ b> A of the mobile terminal 100, and based on the output value from the magnetic sensor 107 changing by a predetermined value or more. Detects the closed state of.

  The network interface 108 transmits / receives data to / from other communication devices via the antenna 108A. Other communication devices include, for example, a server and other communication devices. Portable terminal 100 may be configured to download control program 122 according to the present embodiment via antenna 108A.

  The camera 113 outputs an image signal by shooting according to the control of the CPU 102.

  The storage device 120 is a storage medium such as eMMC (Embedded Multi Media Card). As an example, storage device 120 stores control program 122 according to the present embodiment.

  Note that the control program 122 may be provided by being incorporated in a part of an arbitrary program, not as a single program. In this case, processing according to the present embodiment is realized in cooperation with an arbitrary program. Even such a program that does not include some modules does not depart from the spirit of portable terminal 100 according to the present embodiment. Furthermore, part or all of the functions provided by control program 122 according to the present embodiment may be realized by dedicated hardware. Further, the portable terminal 100 and the server may cooperate to realize processing according to the present embodiment. Furthermore, the mobile terminal 100 may be configured in the form of a so-called cloud service in which at least one server realizes processing according to the present embodiment.

  As described above, the RAM 103 of the mobile terminal 100 sets the sensitivity of the touch operation in a certain range to be the window region in the closed state, and touches the touch screen 111 in the open state where the touch screen 111 is not covered by the cover 200. Stores sensitivity settings for operations. The sensitivity control unit 160 is configured to set the sensitivity of the touch screen 111 in the closed state and the open state based on the settings stored in the RAM 103.

[Control structure of portable terminal 100]
With reference to FIG. 4 and FIG. 5, the control structure of the portable terminal 100 is demonstrated. FIG. 4 is a flowchart illustrating processing in which the mobile terminal 100 sets the touch sensitivity of the touch screen 111. The processing in FIG. 4 is realized by the CPU 102 (see FIG. 2) of the mobile terminal 100 executing the program. In other aspects, some or all of the processing may be performed by circuit elements or other hardware.

  In step S <b> 401, the CPU 102 acquires a window area range when the cover covers the touch screen 111. For example, the CPU 102 performs processing for detecting the range of the window area, reads out the range information 103A stored in the RAM 103, and an input operation in which the user designates the shape of a known cover already distributed in the market. The range of the window area is acquired by accepting.

  In step S <b> 403, the CPU 102 accepts designation of the type of cover attached to the mobile terminal 100 by the user. For example, the CPU 102 receives designation as to whether or not the user has attached a cover of the type that covers the touch screen 111 to the portable terminal 100. When the cover designated by the user is of a type that covers touch screen 111 (YES in step S403), CPU 102 performs the process of step S405, and otherwise (NO in step S403), the process ends. When the user receives an input operation for designating the shape of the cover in step S401, the CPU 102 performs the processing in step S405 according to the designated shape of the cover (YES in step S403), or ends the processing (step NO in S403).

  In step S405, the CPU 102 receives an operation for selecting an application to be displayed in the window area from the user.

  In step S <b> 407, the CPU 102 performs a process of adjusting the sensitivity of the touch operation when the user attaches a protective sheet that protects the touch screen 111 to the touch screen 111. For example, the CPU 102 accepts designation of whether or not a protective sheet is pasted on the touch screen 111 from the user, and when the user pastes the protective sheet on the touch screen 111, the sensitivity of the touch operation needs to be adjusted. Whether or not is received from the user. When it is necessary to adjust the sensitivity of the touch operation, the CPU 102 performs screen display for the user to adjust the sensitivity of the touch operation on the touch screen 111, and accepts the user's operation, whereby the protection sheet is applied to the touch screen 111. Adjust the sensitivity of touch operation when wearing.

  In step S409, the CPU 102 performs a process of adjusting the sensitivity of the touch operation when the cover covers the touch screen 111. For example, the CPU 102 notifies the user by displaying the screen on the touch screen 111 so that the touch screen 111 is closed with the cover. The CPU 102 notifies that the touch screen 111 is covered with the cover until the detection unit 150 detects that the touch screen 111 is covered with the cover. When the detection unit 150 detects that the touch screen 111 is covered with the cover, the CPU 102 receives a user operation through the window area in the closed state where the touch screen 111 is covered with the cover. The CPU 102 performs screen display for the user to adjust the sensitivity of the touch operation in the closed state using the touch screen 111 (particularly, the window region), and accepts the user's operation, thereby allowing the touch operation of the window region and the non-window region to be performed. Adjust the sensitivity.

  In step S411, the CPU 102 receives an input operation for adjusting the range (position and size) of the window region on the touch screen 111 from the user, adjusts the range of the window region in accordance with the user operation, and displays the adjustment result. , And stored as range information 103A in the RAM 103.

  FIG. 5 is a flowchart showing processing for adjusting the touch sensitivity of the window area and the non-window area of the touch screen depending on whether or not the touch screen of the mobile terminal 100 is in the open state. The CPU 102 periodically performs the process illustrated in FIG.

  In step S <b> 501, the CPU 102 determines whether the display unit 105 of the mobile terminal 100 is lit. CPU102 performs the process of step S503, when the display part 105 is lighted, and complete | finishes a process when that is not right.

  In step S <b> 503, the CPU 102 determines whether or not the touch screen is in the closed state covered with the cover based on the detection result of the detection unit 150. If it is determined that it is in the closed state (YES in step S503), CPU 102 performs the process of step S505. If not (NO in step S503), CPU 102 performs the process of step S507.

  In step S505, the CPU 102 sets the touch sensitivity when the touch screen is covered by the cover to the touch screen based on the range of the window area and the range of the non-window area indicated by the range information 103A. Thereby, the portable terminal 100 makes the sensitivity of the touch panel 106 in the non-window area 105B other than the window area 105A in the display area of the display unit 105 lower than the sensitivity of the touch panel in the window area 105A in the closed state of the cover 200. Set.

<Second Embodiment>
Hereinafter, the mobile terminal 100 according to the second embodiment will be described. The mobile terminal 100 according to the second embodiment uses a camera 113 that functions as an in-camera to detect a window area when the cover 200 covers the touch screen 111.

  With reference to FIG. 6 and FIG. 7, the process in which the portable terminal 100 of 2nd Embodiment sets a window area | region is demonstrated.

  FIG. 6 is a diagram illustrating an outline of processing in which the mobile terminal 100 sets the window area 105A using the in-camera.

  As shown in the state (A), the cover 200 does not cover the display unit 105 in the open state of the cover 200. In addition, the mobile terminal 100 includes a camera 113 that functions as an in-camera. In the mobile terminal 100 according to the second embodiment, the camera 113 that functions as an in-camera is disposed at a position along the central axis of the casing, but the arrangement location is not limited to the position along the central axis of the casing. .

  Assume that the cover 200 is closed by the user as shown in the state (B). In this state, the cover 200 is provided with an opening (camera window) corresponding to the position of the camera 113 so that photographing by the camera 113 is possible.

  The state (C) shows an example of a test pattern displayed on the display unit 105 of the mobile terminal 100 in order to detect the shape of the opening 210 using the camera 113 functioning as an in-camera. In the state (C), the mobile terminal 100 displays a grid-like image on the display unit 105 as a test pattern. The mobile terminal 100 displays a test pattern on the display unit 105 in a state where the touch screen 111 is covered by the cover 200 (closed state), and faces the mirror surface (for example, a mirror such as a standing mirror or a wall-mounted mirror) to the user. The camera 113 is used to notify that the cover 200 is to be photographed. It is assumed that the user takes an image with the camera 113 with the opening 210 and the camera 113 functioning as an in-camera facing a mirror surface in a closed state where the cover 200 is closed.

  The state (D) shows a photographed image 115 photographed by the camera 113 toward the mirror surface in a state where the test pattern shown in the state (C) is displayed on the display unit 105 with the cover 200 closed.

  The captured image 115 includes a cover image 200 </ b> A that is a result of capturing the cover 200. The cover image 200A includes an opening image 210A corresponding to the opening 210 and a camera opening image 113A corresponding to the opening of the camera 113. The mobile terminal 100 has a vertical size 210H that is the vertical size of the opening image 210A, a horizontal size 210W that is the horizontal size of the opening image 210A, and the distance between the opening image 210A and the camera opening image 113A. Is calculated based on the captured image 115. Since the size of the mobile terminal 100 and the location where the camera 113 is disposed are known, the mobile terminal 100 determines that the opening image 210A, the camera opening image 113A, the vertical size 210H, the horizontal size 210W, Based on information such as the arrangement interval 117, the shape of the window region is specified. The mobile terminal 100 can specify the vertical and horizontal sizes of the window area, the ratio of the vertical and horizontal sizes, and the shape of the window area in the entire touch screen based on the captured image 115.

  As described above, the mobile terminal 100 includes the camera 113 disposed on the same surface as the surface on which the touch screen 111 is disposed. The CPU 102 causes the touch screen 111 to display a determination image (test pattern) for determining the range of the opening 210. In the closed state, the CPU 102 issues a notification that prompts the camera 113 to take a picture with the touch screen 111 facing the mirror surface. The CPU 102 is configured to detect a certain range (window region) corresponding to the position of the opening 210 based on the photographing result by the camera 113.

  FIG. 7 is a flowchart illustrating processing in which the mobile terminal 100 according to Embodiment 2 sets the window area 105A using the in-camera. The CPU 102 performs the process shown in FIG. 7 in response to an input operation for the user to set the window area 105 </ b> A, for example, by detecting that the cover 200 is in a closed state covering the touch screen 111.

  In step S701, the CPU 102 activates the in camera and notifies the user by voice output or the like so that the in camera is directed to the mirror surface.

  In step S <b> 703, the CPU 102 acquires an image signal output from the in-camera and determines whether or not the cover 200 has an opening corresponding to the position of the camera 113 by image recognition. For example, if the CPU 102 cannot detect the contour such as an edge as a result of image recognition of the image signal, the opening of the camera 113 is not provided in the cover 200 and there is no opening corresponding to the position of the camera 113 ( If it is determined that there is no camera window (NO in step S703) and the process ends and the contour such as an edge is detected, it is determined that the cover 200 has an opening corresponding to the position of the camera 113 ( In step S703, YES), the process of step S705 is performed.

  In step S705, based on the image signal output from the in-camera, the CPU 102 has a recognition rate that distinguishes between the cover image 200A and the opening image 210A that is a test pattern displayed on the touch screen by image recognition above a certain level. The pattern and color scheme of the test pattern displayed on the touch screen are sequentially switched so as to be displayed on the touch screen.

  In step S <b> 707, the CPU 102 detects that the probability that the cover image 200 </ b> A and the opening image 210 </ b> A showing the test pattern can be recognized in accordance with a user instruction is equal to or greater than a certain level. Photographing is performed with a camera, and the photographed image is stored in a memory.

  In step S709, the CPU 102 reads (1) the size (width, height, etc.) of the mobile terminal 100 and the location of the camera 113 in the mobile terminal 100, and (2) based on the captured image 115 obtained in step S707. Recognize the shape of the opening image 210A (the shape of the window region) and the position of the test pattern, and (3) based on information such as the position of the grid indicated by the test pattern, the size of the loaded portable terminal 100, the position of the camera 113, etc. Then, the position and size of the opening 210 (window region) are specified, and the specified position and size of the window region are stored in the memory.

  In this way, by displaying a grid-like image as a test pattern on the display unit and attaching the cover to the mobile terminal 100, the user photographs the user himself with the in-camera (self-portrait) toward the mirror surface. The mobile terminal 100 specifies the shape of the opening 210 (window region) formed in the cover 200 based on the grid specified from the captured image. The portable terminal 100 can improve the specific accuracy of the window region based on the captured image of the in-camera by changing the pattern and color scheme of the test pattern displayed on the display unit according to the color of the cover. Thereby, the portable terminal 100 can detect the window area corresponding to the openings 210 having various shapes formed in the cover 200. Even if the user changes the cover 200 and the shape of the opening 210 and the color scheme of the cover 200 are changed, the mobile terminal 100 changes the window area corresponding to the changed cover 200 according to the change of the cover 200. Can be set.
