  ADVANTAGE OF THE INVENTION According to this invention, the optimal layout according to a user's finger | toe position can be provided.

1 is a block diagram illustrating a configuration of an embodiment of a camera 100. FIG. FIG. 6 is a flowchart showing processing of the camera 100. It is a figure which shows the example of a change of a display layout.

  FIG. 1 is a block diagram illustrating a configuration of an embodiment of a camera according to the present embodiment. The camera 100 includes an imaging unit 101, a CPU 102, a monitor 103, a touch panel 104, a memory 105, and a recording medium 106.

  The imaging unit 101 includes an imaging element such as a CCD or a CMOS, for example, and captures a subject image to acquire image data. The CPU 102 controls the entire camera 100. The CPU 102 functionally includes a finger position detection unit 102a, a holding determination unit 102b, a layout determination unit 102c, and a display control unit 102d. The contents of the processing by these units will be described later. The monitor 103 is, for example, a liquid crystal monitor (rear monitor) mounted on the back surface of the camera 100. The touch panel 104 is disposed on the monitor 103, detects a touch operation by the user, and outputs a detection signal to the CPU 102.

  The memory 105 is configured by SDRAM or flash memory. The SDRAM is a volatile memory, and is used as a work memory for the CPU 102 to develop a program when the program is executed, or as a buffer memory for temporarily recording data. The flash memory is a non-volatile memory in which data of a program executed by the CPU 102, various parameters read when the program is executed, and the like are recorded. The recording medium 106 is a memory card inserted into a memory card slot (not shown), for example, and records image file data and the like generated based on the image data acquired by the imaging unit 101.

  In camera 100 in this embodiment, a user can operate camera 100 using touch panel 104. For example, when a still image being reproduced is displayed on the monitor 103, the user performs a predetermined touch operation on the touch panel 104 to enlarge or reduce the reproduced image or display the next still image. Or instruct it to play. When the menu screen is displayed on the monitor 103, the user touches a button indicating a menu item on the touch panel 104 to instruct to execute a process corresponding to the touched button. Can do. When a live view is displayed on the monitor 103 and a camera operation button (operation icon) is displayed on the live view, the user touches the button on the touch panel 104. By this, it is possible to instruct to execute processing according to the touched button.

  Thus, in the camera 100 equipped with the touch panel 104, the monitor 103 often occupies many portions on the back of the camera 100. In this case, when the user holds the camera 100, the finger is placed on the monitor 103. There is a possibility that it will take. For this reason, if the user's finger hides the display content of the monitor 103 or a button is displayed at the position where the finger is placed, it may be erroneously detected that the button has been operated. In the present embodiment, in order to solve such a problem, the CPU 102 performs processing as follows.

  FIG. 2 is a flowchart showing processing of the camera 100 in the present embodiment. The processing shown in FIG. 2 is executed by the CPU 102 as a program that is activated when display on the monitor 103 is started.

  In step S10, the display control unit 102d displays information on the monitor 103 with a standard layout corresponding to the display content. For example, when the display content is a still image, the still image is displayed on the monitor 103 as shown in FIG. 3A. When the display content is a menu screen, as shown in FIG. The menu screen is displayed on the monitor 103 in full screen, and if it is a through image, as shown in FIG. 3E, the through image is displayed on the monitor 103 and the operation icon is displayed on the through image. To do.

  Thereafter, the process proceeds to step S20, where the CPU 102 resets a timer for measuring the elapsed time since the user touched the touch panel 104, and proceeds to step S30. In step S <b> 30, the finger position detection unit 102 a detects the user's finger position on the touch panel 104 based on the output from the touch panel 104. For example, the touch panel 104 detects a position pressed by the user on the touch panel and outputs a signal indicating the position to the CPU 102. Thus, the finger position detection unit 102a can detect the finger position on the touch panel 104. Thereafter, the process proceeds to step S40.

  In step S40, the holding determination unit 102b determines whether the finger position of the user on the touch panel 104 has changed by a predetermined distance or more based on the finger position detection result in step S30. When a negative determination is made in step S40, the process proceeds to step S50, and the finger position determination unit 102a determines whether or not the user's finger is positioned on the operation icon or menu item. If a negative determination is made in step S50, the process returns to step S20. On the other hand, if a positive determination is made in step S50, the process proceeds to step S60. In step S60, the CPU 102 determines that a touch operation has been performed on the operation icon or menu item by the user, executes processing according to the touch operation, and returns to step S20.

  On the other hand, if a positive determination is made in step S40, the process proceeds to step S70. In step S70, the holding determination unit 102b determines whether or not the elapsed time being measured by the timer is equal to or greater than a predetermined threshold T. If a negative determination is made in step S70, the process returns to step S30. On the other hand, if a positive determination is made in step S70, the process proceeds to step S80.

  In step S <b> 80, since the user's finger is not less than the predetermined time T and is placed at substantially the same position on the touch panel 104, the holding determination unit 102 b uses the touch panel to hold the camera 100. 104 is determined to be placed on the screen. The layout determining unit 102c determines the display layout of the monitor 103 according to the finger position of the user at that time. In the present embodiment, the layout determining unit 102c changes the display layout changing method of the monitor 103 according to the display content of the monitor 103 as shown in FIG.

  Specifically, when the display content of the monitor 103 is an image obtained by shooting a still image, a through image, or the like, the layout determination unit 102c prevents the user's finger position from overlapping the image. Change the size of the image while maintaining the aspect ratio of the image. As a result, the image can be displayed while avoiding the user's finger position, so that it is possible to prevent the image from being hidden by the finger and becoming invisible. In reducing the image, the aspect ratio before the reduction is maintained, so that the appearance of the image is not impaired.

  On the other hand, when the display content of the monitor 103 is a display element for operation such as a menu screen or an operation icon, the layout determining unit 102c prevents the user's finger position from overlapping with the display element for operation. Move the display position of the display element. Accordingly, since the display element can be displayed while avoiding the finger position of the user, it is possible to prevent the display element from being hidden by the finger and becoming invisible.

  For example, as shown in FIG. 3A, when a still image is displayed on the monitor 103, the layout determining unit 102c displays the user's finger position and the still image as shown in FIG. The size of the still image is changed while maintaining the aspect ratio of the still image so that they do not overlap with each other. When the menu screen is displayed on the monitor 103 as shown in FIG. 3C, the layout determining unit 102c displays the user's finger position and the menu screen as shown in FIG. Reduce the menu screen so that and do not overlap. At this time, it is not necessary to maintain the aspect ratio of the menu screen.

  Further, as shown in FIG. 3E, when the through image is displayed on the monitor 103 and the operation icon is displayed on the through image, the layout determining unit 102c displays the operation shown in FIG. As described above, the size of the through image is changed while maintaining the aspect ratio of the through image so that the finger position of the user and the through image do not overlap. Further, the display position of the operation icon is moved so that the finger position of the user and the display position of the operation icon do not overlap.

  Thereafter, the process proceeds to step S90, and the layout determining unit 102c stores the display layout setting value determined in step S80 in the memory 105. As the layout setting value, for example, a reduction ratio (magnification amount) of a still image or a through image and a movement amount (shift amount) of a menu screen are recorded. Thereafter, the process proceeds to step S100, and the display control unit 102d changes the display layout of the monitor 103 according to the display layout determined in step S80, and then proceeds to step S110.

  In step S110, the CPU 102 determines whether or not the user has instructed cancellation of the display layout of the monitor 103. If an affirmative determination is made in step S110, the process returns to step S10 to return the display layout of the monitor 103 to the standard layout. On the other hand, if a negative determination is made in step S110, the process proceeds to step S120. In step S120, the CPU 102 determines whether or not the user has instructed the end of the display on the monitor 103. If a negative determination is made in step S120, the process returns to step S20. On the other hand, when an affirmative determination is made in step S120, the process ends.

According to the present embodiment described above, the following operational effects can be obtained.
(1) The CPU 102 changes the display layout changing method according to the display content of the monitor 103. Thereby, an optimal display layout according to the display content of the monitor 103 can be provided.

(2) The holding determination unit 102b places the user's finger on the touch panel 104 for gripping the camera 100 when the position of the user's finger on the touch panel 104 does not change for a predetermined time T or longer. I decided to judge. This makes it possible to easily and accurately determine whether the user's finger is placed on the touch panel 104 for gripping the camera 100.

(3) When the change of the display layout is canceled by the user, the CPU 102 returns the screen display layout to the standard layout, that is, the state before the layout change. Thus, the user can return to the standard layout at any time even when the display layout is changed.

(4) When the content displayed on the monitor 103 is an image obtained by photographing, the layout determining unit 102c is configured to prevent the image from overlapping with the position of the user's finger on the touch panel. The size was changed (reduced). As a result, the image can be displayed while avoiding the user's finger position, so that it is possible to prevent the image from being hidden by the finger and becoming invisible.

(5) The layout determination unit 102c maintains the aspect ratio before the reduction when reducing the image. As a result, the image can be displayed while avoiding the position of the user's finger without impairing the appearance of the image.

(6) When the content displayed on the monitor 103 is a display element that is not an image obtained by shooting, the layout determination unit 102c overlaps the position of the user's finger on the touch panel 104 with the display element. The display position of the display element was changed so that it would not happen. Accordingly, since the display element can be displayed while avoiding the finger position of the user, it is possible to prevent the display element from being hidden by the finger and becoming invisible.
