  Hereinafter, an electronic camera (imaging device) as an electronic apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a rear view showing an appearance of an electronic camera 2 according to the embodiment. The electronic camera 2 is an electronic camera provided with a waterproof mechanism, and a display unit 4 composed of an LCD or the like is provided on the back. The display unit 4 displays a through image based on an imaging signal from the image sensor 14 (see FIG. 2), a moving image or a still image based on image data recorded on the recording medium 22 (see FIG. 2), and various types. Displays menu screen for setting and information related to shooting.

  In addition, a touch panel 6 and a control button 8 are provided on the back surface of the electronic camera 2 so as to overlap the display screen of the display unit 4. The touch panel 6 detects the position of the finger in contact with the display unit 4 and receives an input operation defined for the detected finger position. The control button 8 is a button for changing the reference position of the tilt angle of the electronic camera 2 when the process based on the detection of the posture change is effective. A release button 10 is provided on the upper surface of the electronic camera 2 to give an instruction to start shooting.

  FIG. 2 is a block diagram showing a system configuration of the electronic camera 2 according to the embodiment. The electronic camera 2 includes a CPU 12 that controls each part in an integrated manner. Connected to the CPU 12 are a display unit 4, a touch panel 6, an image sensor 14, an operation unit 16, an acceleration sensor 18, and a storage unit 20, and a recording medium 22 such as a memory card is connected via a card slot (not shown). Yes.

  The image sensor 14 is configured by a CCD or a CMOS, captures subject light via a photographing lens, and outputs an image signal to the CPU 12. The operation unit 16 includes a control button 8, a release button 10, and the like. The acceleration sensor 18 detects the acceleration in the direction of gravity acting on the electronic camera 2 and outputs it to the CPU 12. Thereby, when the electronic camera 2 is tilted as indicated by the dotted line in FIG. 3 from the horizontal state in which the bottom indicated by the solid line in FIG. 3 is parallel to the horizontal plane, the CPU 12 determines whether the electronic camera 2 is based on the detection result of the acceleration sensor 18. 2 is detected.

  The storage unit 20 stores the processing content and the tilt angle range of the electronic camera 2 associated with the processing content for each processing type such as shooting mode setting processing, shutter speed setting processing, and image feed processing. A table indicating a certain angle range is stored. Note that the inclination angle here is set to 0 ° when the electronic camera 2 is in the horizontal position as shown in FIG. 4, and the counterclockwise direction when the electronic camera 2 is viewed from the back side is set as a positive direction. .

  For example, for the shooting mode setting process, a table indicating five shooting modes and an angle range of an inclination angle associated with each shooting mode is stored. In this table, as shown in FIGS. 4 and 5, the shooting mode 1 is associated with the angle range 311 ° to 330 °, the shooting mode 2 is associated with the angle range 331 ° to 350 °, and the shooting mode 3 is set. An angle range of 351 ° to 10 ° is associated, an angle range of 11 ° to 30 ° is associated with the shooting mode 4, and an angle range of 31 ° to 50 ° is associated with the shooting mode 5.

  For the shutter speed setting process, a table indicating the angle range associated with each shutter speed is stored, and for the image feed process, it corresponds to each number of feeds such as 1, 5, 10 and so on. A table indicating the attached angle range is stored.

  Next, processing for changing the reference position of the tilt angle of the electronic camera 2 and setting the shooting mode will be described. When the user issues a shooting mode setting start instruction by operating the touch panel 6, the CPU 12 detects the tilt angle of the electronic camera 2 based on the detection result of the acceleration sensor 18, and the table stored in the storage unit 20. , The angle range corresponding to the tilt angle and the shooting mode associated with the angle range are specified. The CPU 12 displays a message indicating the specified shooting mode on the display unit 4. The CPU 12 displays a screen showing a plurality of angle ranges and shooting modes as shown in FIG. 4 on the display unit 4 when the start of shooting mode setting is instructed, and how to tilt the electronic camera 2. Then, it may be shown to the user whether a desired shooting mode can be set.

  Here, as shown in FIG. 6A, the normal user holds and operates the electronic camera 2 in a horizontal state. For example, when the electronic camera 2 is operated underwater, the user performs FIG. 6B. In some cases, the electronic camera 2 is operated in a state where the electronic camera 2 is inclined at a predetermined inclination angle θ from the horizontal position.

  Therefore, when the user wants to change the reference position of the electronic camera 2, the control button 8 is pressed to change the reference position of the inclination angle of the electronic camera 2. When the control button 8 is pressed, the CPU 12 detects the tilt angle θ of the electronic camera 2 based on the detection result of the acceleration sensor 18. Then, the CPU 12 stores the storage unit 20 so that the inclination angle θ corresponds to an angle range including the horizontal in the angle range corresponding to each photographing mode (so that a state inclined at the inclination angle θ is regarded as a horizontal state). The angle range associated with the shooting mode of the table stored in is changed.

  For example, when the detected inclination angle θ is an inclination in the positive direction as shown in FIG. 6B, the CPU 12 determines the inclination angle from each angle range associated with the shooting mode as shown in FIG. Subtract θ. If the detected tilt angle θ is a negative tilt, the CPU 12 adds the tilt angle θ to each angle range associated with the shooting mode as shown in FIG.

  After pressing the control button 8, the user performs an operation of tilting the electronic camera 2 again to set the shooting mode, tilts the electronic camera 2 to a desired angle, and releases the control button 8. The CPU 12 refers to the table stored in the storage unit 20 based on the tilt angle detected based on the detection result of the acceleration sensor 18 when the control button 8 is released, and the angle range corresponding to the tilt angle and its angle. The shooting mode associated with the range is specified. Further, the CPU 12 displays a message indicating the photographing mode on the display unit 4. The CPU 12 performs a process for confirming the setting of the specified shooting mode, thereby ending the shooting mode setting process.

  According to the electronic camera 2 according to the present embodiment, the angle range associated with each shooting mode is changed according to the inclination angle of the electronic camera 2, so that the electronic camera 2 is in a state where the user is inclined with respect to the vertical. Even when the button is operated, it is possible to reliably set the shooting mode desired by the user in accordance with the change in the attitude of the electronic camera 2.

  In the above-described embodiment, the shooting mode setting process is performed by tilting the electronic camera 2. However, the present invention is not limited to this, and the image feed process, the shutter speed setting process, and the exposure correction are performed by tilting the electronic camera 2. An amount setting process, an aperture value setting process, an ISO sensitivity setting process, and the like may be performed.

  In the above-described embodiment, the angle range corresponding to each shooting mode is set so that the tilt angle of the electronic camera 2 when the control button 8 is pressed includes the horizontal, that is, the angle range including 0 °. The angle range corresponding to each shooting mode is changed so that the tilt angle of the electronic camera 2 when the control button 8 is pressed is associated with the angle range of the shooting mode set at the previous shooting. You may make it do.

  In the above-described embodiment, when a specific process is associated with an angle range in which it is difficult for the user to tilt the electronic camera 2, for example, an angle range of 51 ° to 70 °, it is easy for the user to handle. Guidance for changing the angle range may be provided. That is, the CPU 12 may display guidance such as “tilt the electronic camera 2 counterclockwise and press the control button 8” on the display unit 4, or output voice guidance from a speaker (not shown).

  In the above-described embodiment, the electronic camera 2 has been described as an example. However, the present invention can also be applied to other electronic devices such as a tablet terminal, a smartphone, and a PDA.
