Touch-off: state in which contact input is not made Note that the GUI touch operation processing of this embodiment will be described below using the above-described six state recognitions, but the designation of the state name and the state that triggers each processing Is an example and is not limited to the following.

  The GUI touch operation processing of the digital camera 100 of the present embodiment having such a configuration will be described with further reference to the flowchart of FIG. The GUI touch operation process is started after the digital camera 100 is activated and the system control unit 50 performs a predetermined process performed at the time of activation, and then the image captured on the display unit 28 is displayed through. Shall. However, the embodiment of the present invention is not limited to the state in which the digital camera 100 is operating for imaging, and can be applied to the state in which the digital camera 100 is operating to view an image recorded on the recording medium 200, for example. It is.

  In step S <b> 201, the system control unit 50 determines the mode set in the current digital camera 100, and reads a combination of GUI buttons that are set in the mode and assigned a function to be displayed on the display unit 28. Specifically, the system control unit 50 refers to a GUI button management table stored in the system memory 52 and acquires information about buttons to be displayed in the current mode of the digital camera 100 and display positions thereof. Then, the system control unit 50 transmits the GUI data of the button to be displayed to the memory 32, superimposes it on the captured image data displayed on the display unit 28, outputs the image data to the D / A conversion unit 13, and D After the / A conversion process is applied, the data is output to the display unit 28. Thereby, in addition to the through display of the captured subject image, a GUI button is superimposed on the display unit 28.

  The digital camera 100 of the present embodiment is provided with a plurality of modes such as an auto imaging mode, a manual imaging mode, and a browsing mode, for example, and buttons having functions that can be executed in each mode are different. For example, when the digital camera 100 is in the auto imaging mode, a GUI button group and its display frame 400 are displayed in the display area of the display unit 28 as shown in FIG. The GUI button group includes, for example, a shooting mode setting button 401, a strobe setting button 402, a self timer setting button 403, a function setting button 404, and a display switching button 405. The user can execute functions assigned to various buttons by selecting these buttons by touch input.

  In S202, the system control unit 50 detects the current contact input state (operation). Specifically, when the coordinate information on the display area where the touch input is made from the touch sensor 70 is received, the received coordinate information is stored in the system memory 52. Further, the system control unit 50 refers to the history information of the coordinate information on the display area where the contact input is made, which is stored in the system memory 52, thereby determining the operation of the contact input being made at present.

  If the touch input operation is a touch-down operation, the system control unit 50 moves the process to S204 (S203). In S204, the system control unit 50 refers to the GUI button management table stored in the nonvolatile memory 56, and determines whether or not the coordinate information of the current contact input is included in the button display area. If the system control unit 50 determines that a contact input has been made in the button display area, the system control unit 50 proceeds to S205. If the system control unit 50 determines that a contact input has been made outside the button display area, the process returns to S202.

  In S205, the system control unit 50 highlights and superimposes the display of the button determined to have been contact-inputted in S204 among the GUI buttons to be superimposed on the image data captured in the memory 32. At this time, the system control unit 50 stores, in the system memory 52, information about the button that is determined to have undergone contact input, for example, as information about the selected button. The system control unit 50 causes the display unit 28 to display the combined image data after the D / A conversion unit 13 applies the D / A conversion process. Thereby, it is possible to present the selected button to the user in an identifiable manner. FIG. 4B shows an example in which the strobe setting button 402 is selected and highlighted from the GUI button group drawn on the display area of the display unit 28 by the user. In step S206, the system control unit 50 sets a timer for generating an event for the currently selected button after a predetermined time has elapsed in the system timer 53, and then returns the process to step S202.

  If the touch input operation is a move operation, the system control unit 50 moves the process to S208 (S207). In S208, the system control unit 50 refers to the GUI button management table stored in the nonvolatile memory 56, and determines whether or not the coordinate information of the current contact input is included in the button display area. If the system control unit 50 determines that a contact input has been made in the button display area, the process proceeds to S210. If the system control unit 50 determines that a contact input has been made outside the button display area, the process proceeds to S209.

  In step S209, the system control unit 50 refers to the information on the selected button stored in the system memory 52. If the selected button exists, the system controller 50 highlights the button highlighted in the memory 32. Switch to the normal display method and synthesize. The system control unit 50 causes the display unit 28 to display the combined image data after the D / A conversion unit 13 applies the D / A conversion process.

  If it is determined in S208 that a touch input has been made in the button display area, the system control unit 50 refers to the GUI button management table stored in the nonvolatile memory 56, and determines the button existing in the coordinate information of the current touch input. Get information. Further, the system control unit 50 refers to the information of the selected button stored in the system memory 52, and determines whether the button that has been determined to be touch-input is the same as the selected button. (S210). That is, the system control unit 50 determines whether the selected button is changed by the move operation. If the system control unit 50 determines that the selected buttons are the same, the process proceeds to S212, which will be described later. If the system control unit 50 determines that the selected buttons are different, the process proceeds to S205. If there is no information on the selected button in the system memory 52, the system control unit 50 moves the process to S205. Further, the system control unit 50 may newly switch highlight display in S205 and set a timer in S206.

  If the touch input operation is a touch-on operation, the system control unit 50 moves the process to S212 (S211). In S212, the system control unit 50 determines from the system timer 53 whether there is an interrupt process due to an event that occurs after a predetermined time has elapsed. The system control unit 50 moves the process to S213 when interrupt processing exists, and returns the process to S202 when interrupt processing does not occur.

  In step S <b> 213, the system control unit 50 acquires GUI data for guidance explaining that the position of the button can be changed by performing a touch-up operation on the user from the nonvolatile memory 56, and transmits the GUI data to the memory 32 to be superimposed. The images are combined so as to be displayed and displayed on the display unit 28. That is, the system control unit 50 proceeds to a process of detecting a touch-up operation and changing the button position when a certain time elapses while a touch input is made while one button is selected from the GUI button group. It becomes possible. Then, the system control unit 50 returns the process to S202.

  If the touch input operation is a touch-up operation, the system control unit 50 moves the process to S215 (S214). In S215, the system control unit 50 determines whether or not the GUI data for guidance explaining that the position of the button can be changed by performing a touch-up operation on the display unit 28 is superimposed. When the guidance is not displayed, the system control unit 50 refers to information on the button selected in the system memory 52. If there is information on the selected button, an explanation display of the function of the selected button is superimposed on the display unit 28 for a predetermined time, and then the process proceeds to S216 to be assigned to the button. Execute the process. For example, when the strobe setting button is selected as shown in FIG. 4B, it is possible for the user to select the strobe behavior at the time of shooting from automatic flashing, flash prohibition, red-eye flashing, and forced flashing. . Then, the system control unit 50 returns the process to S201. If there is no information about the selected button, the process of S216 is not performed.

  If the guidance explaining that the button position can be changed when the touch-up operation is performed in S215 is displayed, the system control unit 50 stops synthesizing the GUI of the button position changeable notification in the memory 32 and performs the process. Move to S217. Then, the system control unit 50 executes a GUI position changing process that causes the user to change the display position of the GUI button group.

Here, the GUI position changing process will be further described with reference to the flowchart of FIG.
In step S <b> 301, the system control unit 50 acquires a changeable notification indicating that the button display position is changeable from the non-volatile memory 56, transmits the changeable notification to the memory 32, and the captured image is displayed on the display unit 28. It is synthesized so that it is superimposed on the data. Then, the system control unit 50 causes the D / A conversion unit 13 to apply the D / A conversion process to the synthesized image data, and displays it on the display area of the display unit 28. At this time, the system control unit 50 also superimposes and displays all GUI buttons displayed in a plurality of modes of the digital camera 100 and a frame indicating a predetermined display position where the buttons can be arranged.

  FIG. 4C shows GUI data including buttons displayed on the display unit 28 in S301. 4C, in addition to the GUI button group and the display frame 400 displayed in the automatic imaging mode, the display unit 28 includes an exposure correction setting button 411 that is not displayed in the automatic imaging mode, a display frame 410 on the left side of the display area, The button display position changeable notification 420 is displayed. In this way, GUI buttons displayed in all modes can be displayed and changed even when the button display position is changed, so that buttons having the same function in all modes can be displayed in the same way. It is possible to display the position. The display frames 400 and 410 indicate the display positions determined so that the buttons can be arranged. In this embodiment, the user arranges the buttons whose display positions are changed in any of the display frames 400 and 410. Is possible. The button display position changeable notification 420 includes a preset selection button 421 that can be selected from a button display position preset pattern, and an end button for ending the state in which the button display position can be changed. 422 is included.

  In S302, the system control unit 50 detects the current contact input state (operation). Specifically, when the coordinate information on the display area where the touch input is made from the touch sensor 70 is received, the received coordinate information is stored in the system memory 52. Further, the system control unit 50 refers to the history information of the coordinate information on the display area where the contact input is made, which is stored in the system memory 52, thereby determining the operation of the contact input being made at present.

  If the touch input operation is a touchdown operation, the system control unit 50 moves the process to S304 (S303). In S304, the system control unit 50 refers to the GUI button management table stored in the nonvolatile memory 56, and determines whether or not the coordinate information of the current contact input is included in the button display area (first). Judgment). If the system control unit 50 determines that a contact input has been made in the button display area, the process proceeds to S305. If the system control unit 50 determines that a contact input has been made outside the button display area, the process proceeds to S308.

  In S305, the system control unit 50 stores the information of the button determined to have been contact-input in the system memory 52 as, for example, the selected button information, and sets the movement flag of the button to ON to store the information in the system memory. 52. At this time, the system control unit 50 stops synthesizing the GUI data of the changeable notification in the memory 32 in order to stop displaying the changeable notification of the display position of the button superimposed on the display unit 28.

  In S <b> 306, the system control unit 50 is selected in the memory 32 to be displayed at another display position different from the display frame arranged when the selected button is selected on the display unit 28. The button GUI is combined. At this time, the system control unit 50 may change the color of the selected button to be combined in the memory 32 (highlight display). For example, as shown in FIG. 4D, when the strobe setting button displayed in the display frame 400 is selected from a group of buttons whose display position can be changed, the selected button is displayed in the display frame. Displayed at 430 protruding from 400. At this time, the button is not displayed in the area of the display frame 400 where the strobe setting button was displayed, and the area becomes a blank area. This allows the user to recognize that the selected button has been selected and moved without being visually recognized by the user's finger or the like.

  In step S <b> 307, the system control unit 50 sets a storage area on the display frame stored when the button having the current movement flag set to ON is touched up at the currently displayed position to the display frame. Are displayed in an identifiable manner (storage position display processing). Specifically, the system control unit 50 refers to the display position of the button for which the current movement flag is set to ON and calculates the storage position so that the storage area on the display frame stores the button. Determine if it is displayed. For example, as shown in FIG. 5, when there are 10 areas in the display frame in which buttons can be arranged on the display unit 28, the display area is divided into 2 parts on the left and right and 5 parts on the top and bottom for each storage area The determined area is assigned. Then, by the user's operation, the storage area is determined by determining in which determination area the button whose movement flag is set to ON (for example, the center coordinates of the button) exists. The storage area on the display frame determined in this way may be identified by superimposing the storage candidate frame 431 on the display frame 400 as shown in FIG. Then, after displaying the storage position, the system control unit 50 returns the process to S302.

  In S308, the system control unit 50 determines whether or not the preset selection button 421 on the button display position changeable notification 420 has been selected. Specifically, the system control unit 50 determines that the preset selection button 421 has been selected when the coordinates where the contact input has been made are within the display area of the preset selection button 421. When the preset selection button 421 is selected, the system control unit 50 stops displaying the display position changeable notification 420 and displays a plurality of button display position patterns preset in the display unit 28 in S309. Let the user select. The preset button display position pattern is stored in, for example, the nonvolatile memory 56 and may be superimposed on the display unit 28 in the form of a GUI. After the button display position pattern is selected by the user, the system control unit 50 changes the button display position to the display position of the selected pattern, and returns the process to S301.

  When the preset selection button 421 is not selected in S308, the system control unit 50 determines whether or not the end button 422 on the button display position changeable notification 420 is selected (S310). Specifically, the system control unit 50 determines that the end button 422 has been selected when the coordinates where the contact input has been made are within the display area of the end button 422. When it is determined that the end button 422 has been selected, the system control unit 50 completes the GUI position change process, and when it is determined that the end button 422 has not been selected, the process returns to S302.

  If the contact input operation is a move operation and the movement flag of the selected button stored in the system memory 52 is ON, the system control unit 50 moves the process to S312 (second determination, S311). In S <b> 312, the system control unit 50 determines whether or not the movement amount of the move operation is equal to or larger than the movement amount determined to move the button. Specifically, the system control unit 50 calculates the movement amount from the coordinate information of the contact input stored in the system memory 52 to the coordinate at which the contact input is currently performed from the start coordinate of the move operation. calculate. Then, the system control unit 50 determines that the display position of the button is moved when the calculated movement operation amount is larger than the information on the movement amount determined to move the button stored in the nonvolatile memory 56, for example. The process proceeds to S313. If the moving amount of the move operation is smaller than the moving amount determined to move the button, the process returns to S302.

  In step S <b> 313, the system control unit 50 moves the display position of the button by following the coordinates acquired from the touch sensor 70 and currently being touched. In step S314, the system control unit 50 performs storage position display processing. When a touch-up operation is performed at the display position of the current button, the storage candidate frame is superimposed on the storage area of the display frame to be stored. .

  In the present embodiment, in the detected move operation, when there is a vertical movement amount of the display area, the button for moving the display position moves along the display frame by the corresponding vertical movement amount. To do. In FIG. 4E, the protruding strobe setting button 430, which is a button for moving the selected display position, is moved by the vertical movement amount of the move operation in a state adjacent to the button display frame 400. Is displayed. A storage candidate frame 431 is superimposed on the display frame 400 in accordance with the display position of the strobe setting button 430. By doing this, when changing the display position of the button in the GUI button group in the display frame displayed in the vertical direction, a button that moves to the side of the display frame is displayed. It is possible to recognize the storage area of the display frame stored in the.

  Further, when the strobe setting button 430 protruding from the display frame 400 is moved to the storage area on the display frame 410, for example, the following operation may be performed. As shown in FIG. 4F, when the touch input point is moved to, for example, a predetermined area set at the center of the display area of the strobe setting button 430 by the move operation, as shown in FIG. As described above, the user can move the button while keeping the finger in contact with the button. By operating in this way, the user can store the buttons stored in the display frame 400 in the display frame 410.

  When the contact input operation is a touch-up operation and the movement flag of the selected button stored in the system memory 52 is ON, the system control unit 50 moves the process to S316 (S315). In S316, the system control unit 50 refers to the display position of the button whose movement flag is set to ON, calculates the storage position, and moves the selected button to a position adjacent to the storage position to display the display unit. 28. In step S317, the system control unit 50 stores the buttons in the storage position and displays them. At this time, if another button is displayed in the storage area of the display frame set as the storage position, the system control unit 50 performs the following process. The system control unit 50 stores the selected button in the storage position and moves another button stored in the storage area to the area where the selected button is stored.

  That is, when a touch-up operation is detected, the strobe setting button 430 that moves the display position moves to a position adjacent to the storage area stored as shown in FIG. As shown in FIG. 4I, the strobe setting button 430 is stored in the storage area, and the display switching button 432 displayed in the storage area is stored before the strobe setting button 430 is moved. Stored in the storage area. As shown in the figure, by drawing a process in which each button is replaced and stored, the user can recognize the replaced button and the moved button.

  After executing the process in this manner, the system control unit 50 returns the process to S301 and causes the display unit 28 to display the GUI data of the button display position changeable notification. If the detected contact input operation is not touchdown, move, or touchup, the system control unit 50 returns the process to S302.

  In this embodiment, in order to change the display position of the button, the operation for moving the button protruding from the display area is illustrated by using the drawing, but the operation for moving and storing the button are illustrated. The operation is not limited to the above, and various modifications are possible.
