In such a case, a display for changing the first display format of the plurality of icons being displayed on the display unit to a second display format that can reduce selection errors of the icons as compared with the first display format. Control step Provided with a door.

  ADVANTAGE OF THE INVENTION According to this invention, the electronic device which can prevent that operation which a user does not intend is performed, and its control method can be provided.

  FIG. 1 is a diagram showing a schematic configuration of an electronic device for explaining an embodiment of the present invention. The electronic device may be anything as long as it has a display unit such as a digital camera or a mobile phone.

  1 includes a display unit 3 such as a liquid crystal display element, a touch panel 1 provided above the display unit 3, a display control unit 4 that controls screen display on the display unit 3, and the entire electronic device. And a control unit 2 that performs overall control.

  The touch panel 1 is a sensor that can detect the position of an object as a point when the object is touched. For example, a resistive film type touch panel can be used.

  The display control unit 4 performs control for causing the display unit 3 to display a plurality of icons to which commands for instructing electronic devices to perform function execution are assigned. This icon may represent a function menu of the electronic device, and if the electronic device has an image reproduction function such as a digital camera, it represents each image to be reproduced. Also good. The display control unit 3 can display a plurality of icons on the display unit 3 in a plurality of types of display formats. In the following description, it is assumed that a plurality of icons can be displayed in two patterns of the first display format and the second display format. The display control unit 4 causes the display unit 3 to display a plurality of icons in any form according to an instruction from the control unit 2.

  FIG. 2 is a diagram showing an example of a screen displayed on the display unit 3 of the electronic device shown in FIG. The screen shown in FIG. 2A is a screen example when 10 icons a to j are displayed in the first display format. The screen shown in FIG. 2B is displayed in a second display format in which the size and interval of each of the ten icons a to j are larger than the first display format shown in FIG. It is a screen example in the case of. In the second display format, ten icons a to j cannot be displayed simultaneously, so icons g to j can be confirmed by scrolling the screen. In the second display format, the size of the icon and the interval between the icons are larger than those in the first display format, so that it is possible to reduce mistakes in selecting an icon by the user compared to the first display format. It is a display format.

  A touch effective range, which is a specific range, is set in the display area of each icon. The touch effective range refers to a range in which contact can be validated when an object touches the icon display area. The effective touch range may be the entire icon display area or a part of the icon display area. In the case where a part of the icon display area is used, for example, as shown in FIG. 3, it is preferable to set a touch effective range having a reduced shape of the icon display area at the center of the display area.

  The control unit 2 determines whether or not the contact point of the object detected by the touch panel 1 is within the effective touch range set in each display area of the plurality of icons displayed on the display unit 3. . In addition, when the control unit 2 determines that the contact point is within the effective touch range, the control unit 2 performs control to execute an operation corresponding to the icon in which the effective touch range including the contact point is set.

  Considering the responsiveness of the touch panel, it is preferable to make the entire display area of the icon a touch effective range. However, as shown in FIG. 2A, when the size of the icon is small and the interval between the icons is narrow, It is preferable that a part of the icon display area is a touch effective range. This is because, when the entire display area of the icon is set to the touch effective range in the display format shown in FIG. 2A, the distance between the adjacent touch effective ranges is shortened, for example, when the user tries to touch the icon b. If the contact position of the finger itself is shifted or the contact point of the object detected on the touch panel 1 is shifted, there is a high possibility that the contact point enters the touch effective range of the adjacent icons a, g, c. This is because an operation different from the operation intended by the user may be executed.

  On the other hand, as shown in FIG. 2B, when the interval between the icons is wide, it is preferable that the entire display area of the icons be the touch effective range. This is because, when the entire display area of the icon is set to the touch effective range in the display format shown in FIG. 2B, the distance between adjacent touch effective ranges becomes long. For example, when the user tries to touch the icon b Even if the contact position of the finger itself is displaced or the contact point of the object detected by the touch panel 1 is displaced, the contact point can enter within the effective touch range of the adjacent icons a, g, and c. This is because there is a low possibility that an operation different from the operation intended by the user is executed.

  Therefore, in the electronic device shown in FIG. 1, the control unit 2 sets the touch effective range to only a part of the display area of each icon in the first display format as shown in FIG. For the display area of each icon in the display format, a touch effective range is set in the entire display area and the above determination is performed. Of course, in each of the first display format and the second display format, an effective touch range is set as shown in FIG. 3, or the entire icon display area in each of the first display format and the second display format. It is also possible to adopt a mode in which an effective touch range is set for the.

  Next, operation of the electronic device illustrated in FIG. 1 will be described.

  FIG. 4 is a flowchart for explaining the operation of the electronic apparatus shown in FIG. When the power is turned on, the control unit 2 displays the menu screen of the electronic device on the display unit 3 in the first display format (step S1). When the touch of the object is detected on the touch panel 1 (step S2: YES), the control unit 2 determines the contact point of the object detected on the touch panel 1 and each icon included in the menu screen displayed on the display unit 3. The touch effective range set in the display area is compared (step S3).

  When the contact point detected in step S2 is in one of the effective touch ranges set in the display area of each icon (step S4: YES), the control unit 2 touches the touch point. A command corresponding to the icon for which the effective range is set is executed, and an operation corresponding to the icon is executed (step S5).

  When the contact point detected in step S2 is not included in any of the effective touch ranges set in the display area of each icon (step S4: NO), the control unit 2 determines that the touch point is within the effective touch range. The number of determinations n determined to have not entered is updated (step S6). Note that the initial value of the determination number n is 0, and the control unit 2 increments the determination number n by 1 and stores it every time a determination of step S4: NO is made.

  Next, the control unit 2 determines whether or not the determination number n exceeds a threshold value. If the determination number n is equal to or less than the threshold (step S7: NO), the process returns to step S2. When the determination number n exceeds the threshold (step S7: YES), the control unit 2 can reduce the selection error of the icon displayed on the display unit 3 more than the display format. The display control unit 4 is instructed to change to a proper display format. As a result, the menu screen is switched from the first display format to the second display format and displayed again (step S8).

  If contact of an object is detected on the touch panel 1 after step S8 (step S9: YES), the control unit 2 displays the contact point of the object detected on the touch panel 1 and the menu screen displayed on the display unit 3. The touch effective range set in the display area of each icon included is compared (step S10).

  When the contact point detected in step S9 is in one of the effective touch ranges set in the display area of each icon (step S11: YES), the control unit 2 touches the touch point. A command corresponding to the icon for which the effective range is set is executed, and an operation corresponding to the icon is executed (step S5).

  When the contact point detected in step S9 is not included in any of the effective touch ranges set in the display area of each icon (step S11: NO), the process proceeds to step S9.

  As described above, according to the electronic device shown in FIG. 1, when the number of times that the contact point of the object detected by the touch panel 1 does not fall within the effective touch range (the determination number n) exceeds a threshold value. The icon displayed on the display unit 3 can be switched to a display format in which the size and interval are increased. If the number of determinations n exceeds the threshold value, it can be determined that icon selection mistakes are frequently made, that is, operation mistakes are likely to occur in the current display format. Therefore, when the number of determinations n exceeds the threshold, switching to a display format that can relatively reduce icon selection mistakes prevents an operation unintended by the user from being performed. It becomes possible.

  Further, according to the electronic device shown in FIG. 1, in the first display format in which an operation unintended by the user is likely to be performed, the touch effective range is set narrow, so that an erroneous operation is effective. Can be prevented. Further, in the second display format that is unlikely to be operated by the user, the touch effective range is set wide, so that the responsiveness of the touch panel can be ensured.

  In the above description, it is assumed that the second display format that can reduce icon selection mistakes is realized by making both the size of the icon and the interval between the icons larger than the first display format. However, you may implement | achieve a 2nd display format by making either one of the magnitude | size of an icon and the space | interval of icons larger than a 1st display format.

  Further, in the flowchart shown in FIG. 4, the processing of step S6 and step S7 may be omitted. That is, after step S4 in FIG. 4: NO, the process may be directly transferred to step S8. From the viewpoint of preventing erroneous operations, even such a method can provide an effect.

  In the above description, two types of display formats are used, but three or more types may be used. Three types of display formats, the first display format, the second display format, and the third display format, are prepared, and (the size and interval of the icon in the first display format) <(second display format Icon size and interval) <(icon size and interval in the third display format). In the flowchart shown in FIG. 4, when the first display format is switched to the second display format in step S8, the number of determinations n is reset thereafter, and the processing of steps S2 to S7 is performed. When the second display format is switched to the third display format, the processing after step S9 may be performed thereafter.

  In this way, it is possible to deal with various users by making it possible to switch between three or more display formats.
