Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
A. Configuration FIG. 1 is a block diagram illustrating a configuration of a mobile terminal 10 including a photographing control apparatus according to the first embodiment. In this figure, the CPU 20 controls each part of the terminal connected via the bus 30 in accordance with an operation event generated by the input part 40. The characteristic processing operation of the CPU 20 according to the gist of the present invention will be described later. The input key / touch panel 41 generates an operation signal corresponding to the user operation. The input unit 40 detects an operation signal generated by the input key / touch panel 41 and generates an operation event to be supplied to the CPU 20.

  The display control unit 50 controls the display of a display unit 51 including, for example, an LCD panel (or an organic EL panel) according to the display control data supplied from the CPU 20 and displays the screen. Under the control of the CPU 20, the wireless communication unit 60 exchanges data with a base station of a mobile communication network via an antenna (not shown) during data communication, and receives and demodulates voice data received via the antenna during voice communication. While outputting to the audio signal processing unit 70, a radio signal obtained by modulating the audio data supplied from the audio signal processing unit 70 is transmitted from the antenna. Under the control of the CPU 20, the audio signal processing unit 70 performs D / A conversion on audio data supplied from the wireless communication unit 60 and generates sound from the speaker 110, or converts the audio signal output from the microphone 120 to A / D. The converted data is supplied to the wireless communication unit 60.

  As shown in FIG. 2, the work memory 80 including a RAM includes a work area WE in which various register / flag data used for processing of the CPU 20 are temporarily stored, shooting direction setting data SH, and shooting order setting data. An area for storing SJ is provided. The shooting direction setting data SH is data for specifying a shooting direction, and is set in a shooting condition setting process described later. The shooting order setting data SJ is data that specifies the order in which the direction (shooting direction) specified by the shooting direction setting data SH is shot, and is set in a shooting condition setting process described later.

  A nonvolatile memory 90 including a flash memory or the like stores user data such as an address book or captured image data. The ROM 100 stores various control program data executed by the CPU 20. The various control programs include photographing condition setting processing and automatic direction photographing processing described later. The camera unit 130 records captured image data (or moving image data) in a predetermined area of the nonvolatile memory 90 under the control of the CPU 20. The electronic compass 140 is composed of a geomagnetic sensor (such as a Hall element) and detects which direction the terminal device 10 is facing.

B. Operation Next, operations of the imaging condition setting process and the automatic direction imaging process executed by the CPU 20 of the terminal apparatus 10 configured as described above will be described with reference to FIGS. Note that the shooting condition setting process and the automatic direction shooting process executed by the CPU 20 correspond to the functions of the shooting control apparatus included in the terminal device 10.

(1) Operation of Shooting Condition Setting Process FIG. 3 is a flowchart showing the operation of the shooting condition setting process. When an operation event for starting this process occurs, the CPU 20 proceeds to step SA1 shown in FIG. 3, and executes automatic shooting direction selection for setting the shooting direction setting data SH described above. Specifically, when proceeding to Step SA1, the automatic shooting direction setting screen shown in FIG. 4 is displayed on the display unit 51, and the direction to be photographed from the eight directions displayed on the screen, for example, “north”, “ If it is “South”, “East”, and “West”, the respective directions are selected by touch operation. The direction selected by the touch operation is added with a check mark, and represents the state set as the shooting direction setting data SH. The set shooting direction setting data SH is stored in the work memory 80.

  Subsequently, in step SA2, automatic photographing order setting for setting the photographing order setting data SJ described above is executed. In this case, the automatic photographing order setting screen shown in FIG. 5 is displayed on the display unit 51, and the photographing order for each direction previously selected from the eight directions displayed on the screen is key-inputted. For example, in the example illustrated in FIG. 5, a state in which “north” is set to “second”, “south” is set to “first”, “east” is set to “fourth”, and “west” is set to “third”. Represent. The set shooting order setting data SJ is stored in the work memory 80.

(2) Operation of Automatic Direction Shooting Process FIG. 6 is a flowchart showing the operation of the automatic direction shooting process. When an operation event for starting this process occurs, the CPU 20 proceeds to step SB1 shown in FIG. 6, and whether setting data (shooting direction setting data SH and shooting order setting data SJ) is stored in the work memory 80. Determine whether. If the setting data is not stored in the work memory 80, the determination result is “NO”, and the present process ends. However, if the setting data is stored in the work memory 80, the determination result is “YES”. The process proceeds to step SB2.

  In step SB2, the initial value “1” is stored in the pointer n indicating the shooting order, and the camera unit 130 and the electronic compass 140 are activated. Subsequently, when proceeding to step SB3, the current direction (the shooting direction of the camera unit 130) is measured based on the output of the electronic compass 140. In this case, as shown in FIG. 7, the display unit 51 functions as a known viewfinder VF, and the captured image is displayed on the screen, and the current direction is displayed in the direction display area DE in the viewfinder VF. It is displayed.

  Subsequently, in step SB4, it is determined whether or not the current direction measured in step SB3 is within ± 5 ° of the n-th direction in the shooting order (the order designated by the pointer n). If the current direction is not within ± 5 ° of the n-th direction in the shooting order, the determination result is “NO”, the process returns to step SB3, and the direction is measured again. For example, when the re-measured current direction falls within ± 5 ° of the n-th direction in the shooting order, the determination result in Step SB4 is “YES”, and the flow proceeds to Step SB5.

  In step SB5, it is determined whether or not the current direction is unphotographed. If the direction has already been photographed, the determination result is “NO”, and the process returns to step SB3. If the current direction is not yet photographed, the determination result is “YES” and the process proceeds to step SB6. In step SB6, an image in the current direction is automatically taken and recorded by the auto shutter without the user pressing the shutter button. As a result, it is possible to automatically shoot in accordance with a pre-specified shooting direction and shooting order.

  In step SB7, the pointer n indicating the order of shooting is incremented and stepped. In the subsequent step SB8, it is determined whether or not the value of the stepped pointer n is larger than “4”, that is, the shooting specified in advance. Judge whether you have taken all the directions. If all the shots have not been taken, the determination result is “NO”, and the process returns to step SB3 described above. On the other hand, when the value of the incremented pointer n exceeds “4” and all the photographing directions designated in advance are taken, the determination result in the above step SB8 becomes “YES”, and this processing is finished.

  As described above, in the first embodiment, the shooting direction setting data SH for specifying the shooting direction (direction) and the shooting order setting data SJ for specifying the shooting order for the specified direction (direction) are set in advance. In addition, if the current direction (the shooting direction of the camera unit 130) acquired based on the output of the electronic compass 140 is within ± 5 ° of the specified order of direction, whether or not the current direction is unphotographed. If the current direction is not photographed, the image of the current direction is automatically captured and recorded by the auto shutter without the user pressing the shutter button. It becomes possible to automatically shoot according to the direction and order.

  The present invention is not limited to the first embodiment described above, and various modifications can be made within the scope of the present invention. As an example, the imaging control device in the present embodiment is not limited to a mobile phone or a smartphone having a camera function and an electronic compass, but a game device, a tablet PC, a laptop / notebook PC, etc. having a camera function and an electronic compass. Needless to say, the present invention can be applied to other electronic devices.

  Further, in the first embodiment described above, it is determined whether or not the current direction acquired based on the output of the electronic compass 140 (the shooting direction of the camera unit 130) is within ± 5 ° of the specified order of directions. Although it discriminate | determines, it is not restricted to this, It is good also as an aspect which discriminate | determines whether it is settled in the angle range set by a user. Furthermore, in the present embodiment, four directions of “north”, “south”, “east”, and “west” are selected as an example of the shooting direction setting data SH. It is also possible to select an arbitrary direction from among the 16 directions.

  In addition, in the first embodiment, an image of the current direction is automatically captured and recorded by the auto shutter without pressing the shutter button by the user. When the direction (photographing direction) falls within a predetermined angle range of the target direction, a notification sound that prompts the user to press the shutter button is emitted from the speaker 110, and the user manually photographs with the notification sound. Is also possible.

  Further, in the first embodiment described above, the direction designated in advance is recorded every time an image is automatically photographed. For example, as in the example illustrated in FIG. 8, “north”, “south”, “ The images recorded by photographing the four directions of “east” and “west” may be combined into one image and displayed on the screen. In this way, unlike panoramic images, it is possible to display only the image in the desired direction on one screen.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. FIG. 9 is a block diagram illustrating a configuration of the mobile terminal 10 including the imaging control device according to the second embodiment. The second embodiment shown in this figure is different from the first embodiment shown in FIG. 1 in that a navigation unit 150 is provided. The navigation unit 150 has a GPS reception function, a map database function, and a map matching function. Under the control of the CPU 20, the map data including the current position acquired by the GPS reception function is searched from the map database, and the corresponding map data The current position is matched on the map screen to display the map screen on the display unit 51, and the traveling direction acquired based on the output of the electronic compass 140 is displayed on the map screen.

  Next, operations of the imaging condition setting process and the automatic direction imaging process executed by the CPU 20 of the terminal device 10 according to the second embodiment will be described with reference to FIGS. Note that the shooting condition setting process and the automatic direction shooting process executed by the CPU 20 correspond to the functions of the shooting control apparatus included in the terminal device 10.

  FIG. 10 is a flowchart showing the operation of the shooting condition setting process according to the second embodiment. When an operation event for starting this process occurs, the CPU 20 proceeds to step SC1 shown in FIG. 10 and executes automatic shooting location designation. Specifically, position data representing an automatic shooting location is specified by touching a position where automatic shooting is desired on the map screen displayed on the display unit 51. The position data designated by the touch operation is stored in the work memory 80. When there are a plurality of positions where automatic photographing is desired, these positions are designated by touch operation.

  Subsequently, in step SC2, a direction for automatic photographing is set for each automatic photographing place designated in step SC1. Specifically, direction data representing the direction of automatic shooting is set by dragging the automatic shooting location specified on the map screen displayed on the display unit 51 to the direction of automatic shooting. The direction data set by the drag operation is stored in the work memory 80.

  Next, the operation of the automatic direction photographing process according to the second embodiment will be described with reference to FIG. When an operation event for starting this process occurs, the CPU 20 proceeds to step SD1 shown in FIG. 11, and includes the shooting conditions (position data and direction data) stored in the work memory 80 by the shooting condition setting process described above. Read out the first shooting condition. Subsequently, in step SD2, the camera unit 130, the electronic compass 140, and the navigation unit 150 are activated, and the current position and traveling direction are acquired based on the output of the activated electronic compass 140 and navigation unit 150.

  In step SD3, it is determined whether or not the current position acquired in step SD2 matches the shooting location specified by the shooting conditions (position data). If the current position does not match the shooting location, the determination result is “NO”, and the process returns to step SD2. However, if the current position matches the shooting location, the determination result in step SD3 is “YES”. Thus, the process proceeds to step SD4.

  In step SD4, it is determined whether or not the traveling direction acquired in step SD2 matches the direction specified by the shooting conditions (direction data). If the traveling direction does not match the shooting direction, the determination result is “NO”, and the process returns to step SD2. However, if the traveling direction matches the shooting direction, the determination result in step SD4 is “YES”. In step SD5, the image of the current direction is automatically taken and recorded by the auto shutter without the user pressing the shutter button. As a result, it is possible to automatically shoot according to a pre-designated shooting location and shooting direction.

  Subsequently, in step SD6, it is determined whether or not the next shooting conditions (position data and direction data) are stored in the work memory 80. If there is the next shooting condition (position data and direction data), the determination result is “YES”, and after proceeding to step SD7, the next shooting condition (position data and direction data) is read from the work memory 80. The process returns to step SD2 described above. Thereafter, the above-described steps SD2 to SD7 are repeated for all photographing conditions. When the automatic shooting is completed for all shooting conditions, the determination result in step SD6 is “NO”, and the process is completed.

  As described above, in the second embodiment, shooting conditions including position data for specifying a shooting location and direction data for specifying a shooting direction (direction) are set in advance, and the electronic compass 140 and the navigation are set. When the current position and the traveling direction are acquired based on the output of the unit 150, the acquired current position matches the shooting location specified by the position data, and the acquired traveling direction matches the shooting direction specified by the direction data In addition, since the image of the current direction is automatically taken and recorded by the auto shutter without the user pressing the shutter button, the image can be automatically taken according to the pre-designated shooting location and shooting direction. It becomes possible.

  In the second embodiment, the shooting location and the direction are specified in advance, but the map is matched to a nearby road from the current position obtained from the GPS reception function and the road direction information on the map database. It is also possible to obtain at least one direction, for example, a traveling direction, or obtain road direction information of an intersection, from the updated current position later as the shooting location and the road direction information from the updated current position.

  In the first embodiment and the second embodiment, the direction from the electronic compass was obtained and photographed, but in addition to the electronic compass, a combination with two or more gyroscopes, or a three-axis gyro sensor in which the direction information was preset, The direction may be a three-dimensional direction.
