Description

  The present invention relates to a technique of an imaging control method in a mobile terminal.

  A portable terminal having an imaging function capable of imaging by a touch panel operation on a liquid crystal display is configured to acquire a captured image when a finger or the like touches the touch panel and the focal length is adjusted and the finger is released. With this configuration, the user can acquire a captured image only with a finger touch operation.

  However, in the case of this operation by the user's finger, even if it is determined that the current captured image is not necessary after the user touches the touch panel, the image is taken if the finger is released. After that, in order not to save the picked-up image that has been picked up, it is only possible to select not to save or to delete the saved image by a function that prompts the user to determine whether or not to save.

  In the system of Patent Document 1, an electronic camera that performs a plurality of shooting preparation processes and shooting processes by a pressing load on a touch panel is disclosed.

[About mobile terminal configuration]

  Hereinafter, an embodiment of a mobile terminal according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an external view showing an example of the external appearance of a mobile terminal 100 according to the present invention. The mobile terminal 100 of the present invention includes a display unit 101 having a touch panel function and a button 102 like a personal digital assistant (PDA) or a smartphone, for example. The display unit 101 is an electronic component that combines a display control unit such as a liquid crystal panel and a position input control unit such as a touch pad, and is also called a touch panel.

  The touch panel of the display unit 101 is a capacitive projection type that detects a position by detecting a change in capacitance between a fingertip and a conductive film, and has a multi-touch function capable of detecting the position of a plurality of points. It is a multi-touch screen. Since the multi-touch function that can detect the position of two fingers is a known technique, a detailed description thereof is omitted.

  The button 102 is a button for ending an application program (hereinafter simply referred to as an application) being executed on the mobile terminal. The application is started by double-clicking (touching twice) the application icon displayed on the screen using the touch panel function of the display unit 101.

  The back surface of FIG. 1 has an imaging lens 103 for imaging with a mobile terminal, and the imaging lens 103 can capture an image on the back side of the mobile terminal.

  The mobile terminal 100 may have other communication functions and the like, but description thereof is omitted because it is not directly related to the present invention.

  A hardware configuration of the portable terminal 100 that can be easily carried, such as the smart device shown in FIG. 1, will be described with reference to FIG. The CPU 201 comprehensively controls each device and controller connected to the system bus 204.

  Further, the ROM 202 or the flash memory 214 (storage means) is for realizing a BIOS (Basic Input / Output System), an operating system program (hereinafter referred to as OS), which is a control program of the CPU 201, and a function executed by the portable terminal 100. Various programs to be described later are stored. The RAM 203 functions as a main memory, work area, and the like for the CPU 201.

  The CPU 201 implements various operations by loading a program necessary for execution of processing into the RAM 203 and executing the program. Further, the mobile terminal 100 is provided with GPS receiving means 215 (position information acquiring means) that can receive a signal from a GPS satellite and acquire current position information. The CPU 201 receives GPS signals from the GPS receiving means 215. Coordinate information (position information) acquisition control is performed.

  The input controller 205 controls input from the touch panel 210, the microphone 211, and the camera 212. The touch panel 210 controls input related to a user's touch operation, the microphone 211 controls input of sound, and the camera 212 (imaging means) controls input of captured still images and moving images. The output controller 206 controls image output to the touch panel 210 and sound output to the speaker 213.

  The touch panel 210 detects a touch operation from the user and displays the video (image) sent from the output controller 206 described above. The touch panel 210 is a component in which a display and a position input device are integrated. Touch operations (hereinafter referred to as multi-touch) for a plurality of locations can also be detected.

  A memory controller (MC) 207 controls access to the flash memory 214 that stores a boot program, browser software, various applications, font data, user files, editing files, various data, and the like. In the present embodiment, the flash memory is described, but a storage medium such as a hard disk (HD), a flexible disk (FD), or a card type memory connected to a PCMCIA card slot via an adapter may be used.

  The communication I / F controller 209 connects and communicates with an external device via a network, and executes communication control processing on the network. For example, Internet communication using TCP / IP is possible. And the portable terminal 100 can transmit the coordinate information etc. which were received by the GPS receiving means to the web conference server 103 via such a network.

  Note that the CPU 201 enables display on the touch panel 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example.

Various programs and the like used for the portable terminal 100 of this embodiment to execute various processes described later are recorded in the flash memory 214 and can be executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and various information tables used by the program according to the present embodiment can also be stored in the flash memory 214.
[About imaging operation of mobile devices]

  Next, the flow of the imaging process of the mobile terminal 100 according to the present invention will be described with reference to FIG.

  FIG. 3 is a flowchart for describing the imaging operation of the mobile terminal 100 of the present embodiment. Each process in this flowchart is realized by the CPU 201 developing a program stored in the flash memory 214 or the like in the RAM 203 and executing the program.

  First, in the mobile terminal 100, using the touch panel function of the display unit 101, by double-clicking the icon of the imaging application displayed on the screen, the imaging application is activated and the flowchart of FIG. 3 is started.

  In step S301, the CPU 201 of the mobile terminal 100 first generates and displays two buttons for the user to press on the touch panel. An example in which two buttons are displayed will be described with reference to 500 in FIG.

  FIG. 5 is a schematic diagram illustrating a screen image of the display unit 101 at the time of imaging of the mobile terminal 100 of the present embodiment.

  500 in FIG. 5 is a screen image on the display unit 101 (touch panel 210) of the portable terminal 100, and two buttons 501 and 502 are displayed on the touch panel 210. By adopting a configuration in which imaging is not performed unless these two buttons are pressed, the invention makes it easy to cancel imaging even after touching the touch panel. Note that when the end button 504 is pressed, the imaging application is ended. Returning to the flowchart of FIG.

  Next, in step S <b> 302 of FIG. 3, the CPU 201 of the mobile terminal 100 displays an image captured through the imaging lens 103 on the display unit 101 as a live view. The displayed example will be described with reference to 500 in FIG.

  In 500 of FIG. 5, a live view image like 503 is displayed on the display unit 101. In addition, by displaying the two buttons 501 and 502 on the layer displaying the live view, the two buttons 501 and 502 are displayed while displaying the live view. Returning to the flowchart of FIG.

  Next, in step S303 in FIG. 3, the CPU 201 of the portable terminal 100 determines whether one of the two buttons 501 and 502 has been pressed.

  If one of the two buttons 501 and 502 is pressed, the process proceeds to the next step S305, and if one of the two buttons 501 and 502 is not pressed, The process proceeds to step S304.

  When the process proceeds to step S304, the CPU 201 of the portable terminal 100 determines whether or not the end button 504 is pressed. When the end button 504 is pressed, the processing of the present invention is ended and the imaging application is ended.

  On the other hand, if the end button is not pressed in step S304, the process returns to step S302, and a process for displaying a live view is performed.

  If it is determined in step S303 that one of the two buttons 501 and 502 (first button) has been pressed, the process proceeds to the next step S305. In step S305, the portable terminal A CPU 201 of 100 performs imaging preparation processing. Specifically, distance measurement processing is performed on the image being captured to focus the imaging lens 103 on the subject (autofocus processing), and photometry processing is performed to determine the aperture value and shutter speed (exposure determination). processing). In the photometric process, a flash is set if necessary. At this time, if a face is detected, it is also possible to perform face autofocus that performs distance measurement within the detected face range. An example in which the first button is pressed will be described with reference to 510 in FIG.

  510 in FIG. 5 is a screen image on the display unit 101 (touch panel 210) of the mobile terminal 100, and is an image in which the user touches 502 on the touch panel 210. At this stage, the CPU 201 of the mobile terminal 100 executes imaging preparation processing (autofocus processing and exposure determination processing). Reference numeral 511 denotes an image showing the result of executing the face autofocus. At this stage, the captured image is not stored in the flash memory 214. Returning to the flowchart of FIG.

  Next, in step S306 in FIG. 3, the CPU 201 of the portable terminal 100 divides the processing depending on whether the first button pressed in step S303 is kept pressed or released. If the first button has been released in step S306 (the finger has been removed), the process returns to step S302, and a process for displaying a live view is performed. With this determination branch, the imaging operation can be stopped without storing the captured image even after the user once touches the touch panel.

  On the other hand, if the first button remains pressed in step S306, the process proceeds to step S307.

  In step S307, the CPU 201 of the mobile terminal 100 determines whether another button (second button) of the two buttons 501 and 502 has been pressed.

  If the second button is pressed in step S307, the process proceeds to step S308 to store the captured image, and the subsequent processes are continued. If the second button is not pressed, the process returns to step S305, and the imaging preparation process is performed again. In addition, whenever it returns to the process of step S305, the process which displays the image currently imaged on the display part 101 as a live view is also performed in step S305.

  When the process proceeds to step S <b> 308, the CPU 201 of the mobile terminal 100 stores the captured image in the flash memory 214. An example of pressing the second button will be described with reference to 520 in FIG.

  520 in FIG. 5 is a screen image on the display unit 101 (touch panel 210) of the mobile terminal 100, and is an image in which the user touches 501 while touching 502 on the touch panel 210. At this stage, the CPU 201 of the mobile terminal 100 executes an imaging process, that is, a process of storing the captured image in the flash memory 214. Returning to the flowchart of FIG.

  Next, in step S309 in FIG. 3, the CPU 201 of the mobile terminal 100 performs the same imaging preparation process as in step S305.

  In the next step S310, the CPU 201 of the mobile terminal 100 determines whether or not the first button has been released (finger is released). If the first button has been released, the process proceeds to step S312 to execute a captured image confirmation screen display process. On the other hand, if the first button is being pressed (touched) by the user, the process proceeds to step S311 to execute processing for continuing imaging.

  When the process proceeds to step S311, the CPU 201 of the mobile terminal 100 determines whether another button (second button) of the two buttons 501 and 502 is pressed. If the second button is pressed, the process proceeds to step S308, and the imaging process is executed again. On the other hand, if it is determined that the second button has not been pressed, the process proceeds to the imaging preparation process again, and the imaging is always possible.

  If the first button is released in step S310, the process proceeds to step S312 and the CPU 201 of the mobile terminal 100 stores the captured image captured immediately before in the flash memory for confirmation of the captured image. The data is read from 214 and displayed on the display unit 101.

  By performing the processing from step S308 to step S312, the user presses the second button while pressing the first button, and after shooting, if the first button is not released, the live view continues in the shooting mode. The displayed image can be continued, and when the first button is removed, the image reproduction mode is entered and the captured image can be confirmed. With these processes, if the setting is made so that a confirmation screen is displayed for each imaging as in the conventional portable terminal 100, an imaging opportunity may be missed when continuous imaging is desired, but the imaging opportunity is missed. If you want to check the captured image when the setting is made so that the confirmation screen is not displayed for each image capture (the setting to continue image capture), the image capture mode is temporarily exited and the image view mode is entered. Even without this, there is an advantage that the immediately preceding captured image can be confirmed.

  In step S <b> 312, the CPU 201 of the portable terminal 100 accepts a captured image confirmation process from the user, reads the captured image from the flash memory 214, and causes the user to sequentially browse in the order of imaging. Since the browsing process of the captured image to the user is a known technique, detailed description thereof is omitted.

  Next, in step S313, the CPU 201 of the mobile terminal 100 performs the process in step S302 when the user presses a confirmation screen end button (not shown) or when there is no user operation for a certain time (timeout). Return to the display process and continue the imaging application.

  As described above, the imaging processing by the two buttons cancels the imaging even when the finger pressing load as in the cited document 1 cannot be felt, for example, when the touch panel is operated while wearing gloves. can do. In addition, by arranging the two buttons at both ends of the touch panel, there is an advantage that a right-handed user or a left-handed user can easily perform an imaging operation.

  The display positions of the two buttons may be arranged at both ends of the touch panel 210 as in 501 and 502, or may be arranged at either one. For example, when the portable terminal is held vertically (the long side direction is perpendicular to the ground), two buttons may be arranged below the touch panel 210.

  The flowchart of FIG. 3 will be described with reference to the state transition diagram of FIG.

  FIG. 4 is a state transition diagram illustrating an imaging state of the mobile terminal 100 according to the present embodiment. Each state in this state transition diagram is a state that is changed by an operation of the touch panel 201 of the mobile terminal 100.

  First, the mobile terminal 100 transitions from the imaging application start state 400 to a state where no button is pressed (button not pressed state) 401. Thereafter, when the first button is pressed, the mobile terminal 100 transitions to the imaging preparation state 402, and when the first button is stopped, the portable terminal 100 transitions to the button non-pressed state 401. In the imaging preparation state 402, the mobile terminal 100 executes an autofocus process and an exposure determination process for the image being captured.

  When the second button is pressed from the imaging preparation state 402, the state transitions to the imaging state 403. In the imaging state 403, the mobile terminal 100 stores the image being captured in the flash memory 214. The captured state 403 may store captured images while the second button is pressed (that is, continuous shooting state).

  When the second button is stopped (released) after the transition to the imaging state 403 once, the mobile terminal 100 transitions to the imaging preparation state (after imaging) 404, which is different from the imaging preparation state 402. It becomes a transition state. In the imaging preparation state (after imaging) 404, if the second button is pressed, the state transitions to the imaging state 403 as in the imaging preparation state 402, but 1 in the state of the imaging preparation state (after imaging) 404. When the pressing of the first button is stopped (released), the mobile terminal 100 transitions to the captured image confirmation screen state 405, and is in a state in which the captured image is released and the captured image can be viewed by a user operation. To do.

  Subsequently, when the confirmation screen end button is pressed or a timeout is received from the captured image confirmation screen state, the mobile terminal 100 transitions to a button unpressed state. When the application end button is received, the state transits to the end state 406 of the imaging application.

  As described in the above state transition diagram, the present invention is characterized in that the imaging can be easily canceled in the imaging preparation state 402, and the imaging is continuously performed from the imaging preparation state (after imaging) 404. Another feature is that it is easy to select whether to display a confirmation screen.

  With the above process, it is possible to realize a process for easily canceling the imaging process even after the user has touched the touch panel.

  In addition, although described in the embodiment in which the imaging process is executed when the second button is pressed while the first button is pressed, the first button is pressed after the first button is pressed. The imaging process may be performed by releasing from the touch panel and pressing the second button. In that case, in order to cancel the imaging process after pressing the first button, it can be realized by a process of pressing the first button again.
