[Example 1]
Hereinafter, display control according to the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 3 is a flowchart of display control according to the first embodiment of the present invention, and FIG. 4 is a diagram illustrating a touch detection area and a selection control icon according to the first embodiment of the present invention. First, in the standby state of the camera (S301), it is detected whether or not the operation SW is pressed (S302) and waits until the operation SW is pressed.

  When the camera shooting mode selection button, setting button 203, or the like is pressed, the panel state detection unit 109 checks whether the display surface of the display panel 112 of the vari-angle unit 207 is closed (S303). That is, it is determined whether the display surface is facing the camera body 201 or the photographer.

  Here, when the display surface state is closed, that is, when the display surface is directed to the camera body 201 side, the display panel display or touch panel setting is not performed, and the process proceeds to camera control (S311). If the display surface state is a state other than the closed state in the display surface closed state detection (S303), the camera setting state and the like are displayed on the display panel 112 (S304).

  Further, it is detected whether the vari-angle unit 207 is closed by the camera body 201 (S305). If the display surface is facing the photographer, the process proceeds to (S312) and the touch detection area is set. As shown in FIG. 4A 401, the entire area is set in the same range as the display panel 112.

  4A shows the display state of the display panel 112 and the detection state of the touch panel 110 when the display surface of the display panel 112 of the vari-angle unit 207 faces the photographer and is closed by the camera unit. Is shown. FIG. 4B shows other states, that is, the display state of the display panel 112 and the detection state of the touch panel 110 when the vari-angle portion 207 is open.

  Next, the detection method of the touch panel is set to normal (S313). In this embodiment, a capacitive touch panel is used. Capacitive touch panels can change the detection sensitivity and detection method. For example, the detection method is a mutual scan method for contact detection or a mutual scan method for proximity detection. There are high sensitivity settings and hover scan methods.

  The contact detection detects the touch position when the touch panel surface is touched with a finger, and the proximity detection can be detected only by bringing the finger close to the touch panel surface. The setting in (S313) is set to a normally used contact detection method.

  Next, a selection control icon such as 402 in FIG. 4A is displayed on the display panel as an indicator for touch detection of the operation mode and various settings (S314). The selection control icons are evenly arranged on the entire display unit. Whether or not a touch operation is performed in this state is detected (S309), and this state is waited until the touch is performed. When the touch is detected (S309), the detected touch coordinates are transmitted to the CPU.

  The CPU 106 determines the position of the selection control icon from the received touch coordinates, and controls the camera according to a preset camera setting for each icon (S311). In (S305), if the vari-angle unit 207 is not closed by the camera body 201, the process proceeds to (S306), and the touch detection area is set as shown in FIG.

  Next, the touch panel detection method is set to the proximity detection method described above (S307). Subsequently, a selection control icon such as 404 in FIG. 4B is displayed on the display panel as an index for detecting the operation mode and various settings (S308). Here, the touch detection area is also narrowed with respect to the closed state of the vari-angle portion, and the selection control icons are arranged almost evenly corresponding to the detection area. From this state, the sequence of touch detection (S309), transmission of touch coordinates to the CPU (S310), and camera control (S311) is the same as the above-described operation, and a description thereof will be omitted.

  As described above, according to the first embodiment, when the vari-angle unit 207 is open with respect to the camera body 201, the touch detection region is narrowed and the touch detection method is set to proximity detection, thereby enabling touch panel operation. This makes it possible to detect a touch without causing an inadvertent change in angle of the vari-angle display surface due to, and further preventing erroneous touch detection.

[Example 2]
The display control according to the second embodiment of the present invention will be described below with reference to FIGS. FIG. 5 is a flowchart of display control according to the second embodiment of the present invention, and FIG. 6 is a diagram illustrating a difference area of the touch detection method according to the second embodiment of the present invention.

  In the figure, (S301) to (S311) are the same as the flowchart of the display control described in FIG. If the vari-angle portion 207 is not closed by the camera body 201 in (S305), it is further determined whether or not the vari-angle portion 207 is in the abutting position in FIG. 6A in the opening direction. (S501).

  In FIG. 6, FIG. 6A shows that the vari-angle portion 207 is in the abutting position in the opening direction with respect to the camera body 201 in a top view of the camera. If it is determined in (S501) that the vari-angle portion 207 is the abutting position in the opening direction, the process proceeds to (S502), and the touch detection area is set as shown in FIG.

  Next, the difference between the detection area of the touch panel and the detection method is divided and set in areas as indicated by reference numerals 602 and 603 in FIG. Here, in the area 602 in FIG. 6, the touch detection method is set to the contact detection method, and the area 603 in FIG. 6 is set to proximity detection (S503). The area 602 in FIG. 6 is the upper and lower central portion of the display surface facing the hinge 206.

  Subsequently, a selection control icon such as 604 in FIG. 6C is displayed on the display panel as an index for detecting the operation mode and various settings (S504). Here, the touch detection area is also narrower than the vari-angle portion is closed, and the arrangement and number of selection control icons are different depending on the touch detection method. From this state, the sequence of touch detection (S309), transmission of touch coordinates to the CPU (S310), and camera control (S311) is the same as the operation described in the first embodiment, and the description is omitted.

  FIG. 7 is a diagram showing an area-specific index display of the touch detection method according to the second embodiment of the present invention. 7A shows a vari-angle closed state, and in FIG. 2F, an indicator for notifying that the touch detection method is the contact detection method is displayed in a predetermined color on the left end 701 of the display panel 112. FIG. 7B shows an indicator that informs that the touch detection method in the middle state of FIG. 2B in which the vari-angle portion 207 is opened or in the middle state of rotation FIG. 2D is the proximity detection method. Is displayed in a color different from 701 at the left end 702 of the screen. FIG. 7C shows that when the vari-angle portion 207 is in the abutting position in the opening direction, the screen upper and lower center image touch detection method is contact detection, and the upper and lower portions indicate that the touch detection method is proximity detection. They are displayed in the colors 701 and 702 on the left end of the panel 112, respectively.

  As described above, according to the second embodiment, when the vari-angle portion 207 is in the abutting position in the opening direction with respect to the camera body 201, the touch detection area is narrowed and the touch detection method is opposed to the hinge. By using touch detection at the center and proximity detection as the touch detection method for the upper and lower parts, it is possible to maintain the ease of touch by utilizing the fact that the vari-angle display surface by the touch panel operation is difficult to move. ing. In addition, since the touch detection area is also narrowed, touch detection can be performed while preventing erroneous touch detection.

As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
