<Camera module 20>
The camera module 20 is configured to include a camera module control unit 21, a blade drive unit 22, an aperture mechanism 23, and an imaging element 24.

<Image sensor 24>
The image sensor 24 is a so-called photoelectric conversion element that receives light incident from a subject through a lens and converts the light into an electrical signal to obtain image data. Acquisition of image data of a subject is referred to as "shooting". The imaging device 24 is, for example, a CCD or a CMOS sensor. The camera module 20 of the smartphone 1 of the present embodiment does not have a shutter device, and executes imaging by controlling an imaging element.

The throttling mechanism 23 has an opening whose diameter can be changed in accordance with the operation of these blades. That is, the edges of these blades form an opening, and the size of the opening changes as the blades operate. The diaphragm mechanism 23 changes the size of the opening to change the amount of light incident on the imaging device disposed behind the diaphragm mechanism 23 with respect to the subject. This opening is also referred to as a stop opening.

  Note that the diaphragm mechanism 23 may have a multistage or stepless configuration in which the size of the diaphragm opening can be adjusted in a plurality of stages, or a configuration in which the size of the diaphragm opening can be adjusted in two stages or three stages, etc. It may be

<Winger drive unit 22>
The blade drive unit 22 drives a blade that changes the size of the opening of the diaphragm mechanism. The blade drive unit 22 is an electromagnetic actuator including a coil which is excited by a given electric power to be an electromagnet and a permanent magnet. The blade drive unit 22 drives the blades of the diaphragm mechanism when power is supplied, and thereby the size of the opening of the diaphragm mechanism 23 changes. In addition, the structure of the blade | wing drive part 22 is not limited to said structure, The other structure which can drive a blade | wing may be employ | adopted.

<Camera module control unit 21>
The camera module control unit 21 controls the blade drive unit 22 and the imaging device 24 according to an instruction from the processor 10 to execute shooting of an object. Specifically, when receiving an instruction from the processor 10 to change the size of the opening of the aperture mechanism 23, the camera module control unit 21 operates the blade drive unit 22 to make the opening of the aperture mechanism 23 desired. Adjust to size. Next, upon receiving a shooting command from the processor 10, the camera module control unit 21 controls the image sensor 24 to shoot a subject. The camera module control unit 21 is an example of the “diaphragm control unit” in the present invention.

<Operation of shooting process>
Next, a photographing process performed by the smartphone 1 of the present embodiment will be described. FIG. 2 is a flowchart showing the photographing process in the smartphone 1 of the present embodiment.

<S100 to S110>
When the user operates the touch panel 12 so that the user activates the camera mode, the touch panel control unit 11 outputs the operation information to the processor 10, and the processor 10 starts the camera mode accordingly (S100). Next, the processor 10 operates the imaging element 24 via the camera module control unit 21 to start acquisition of the image of the subject. The image captured by the imaging device 24 is displayed on the display unit 14 in real time via the camera module control unit 21, the processor 10, and the display control unit 13 (S110). The image displayed on the display unit 14 in real time is not necessarily stored in the memory 15.

<S120>
Next, the processor 10 displays an icon 101 a (or 101 b) for adjusting the size of the opening of the aperture mechanism 23 on the display unit 14, and the user operates the touch panel 12 or the user's voice input by the microphone 17. To detect

  FIGS. 3A and 3B show the display state of the display unit 14 at this time. The size of the opening of the diaphragm mechanism 23 is different between FIG. 3 (a) and FIG. 3 (b). Specifically, in FIG. 3 (a), the diaphragm aperture is relatively small, and in FIG. 3 (b), the diaphragm aperture is relatively large.

  The touch panel 12 detects, in the vicinity of the icon 101a (or 101b) displayed on the display unit 14, whether a pinch-in operation or a pinch-out operation is not performed by a pointing tool such as a user's finger. That is, when an indicator such as a finger of the user touches the touch panel 12 at two places, and the operation in which the distance between the two indicators approaches from this state is performed, the processor 10 determines that the pinch-in operation has been performed. . On the other hand, when the pointing device such as the finger of the user touches the touch panel 12 at two places, and the operation of separating the two pointing devices from this state is performed, the processor 10 determines that the pinch out operation is performed. Do. The determination of the pinch in operation and the pinch out operation may be performed not on the processor 10 but on the touch panel 12 or the like.

  In accordance with the operation detection by the touch panel 12, the microphone 17 detects a voice input by the user's voice and determines whether or not there is an instruction for adjusting the aperture. Specifically, the processor 10, to which the voice data of the voice acquired by the microphone 17 is input, determines whether this voice data includes a voice of "dark" or "bright".

  As a result of detection using the touch panel 12 and the microphone 17, an operation of opening or closing the aperture is performed as follows.

<S121>
When the processor 10 detects a pinch in operation, the processor 10 drives the diaphragm mechanism 23 via the camera module control unit 21 and the blade drive unit 22 to operate to close the diaphragm opening (make the opening smaller).

<S122>
On the other hand, when the processor 10 detects a pinch out operation, the processor 10 operates the diaphragm mechanism 23 via the camera module control unit 21 and the blade drive unit 22 to open the diaphragm opening (increase the opening). Let

<S123>
On the other hand, when the processor 10 detects the user's voice "dark", the processor 10 drives the diaphragm mechanism 23 via the camera module control unit 21 and the blade drive unit 22 to close the diaphragm opening (the opening is reduced) To operate).

<S124>
On the other hand, when the processor 10 detects the user's voice “bright”, the processor 10 drives the diaphragm mechanism 23 via the camera module control unit 21 and the blade drive unit 22 to open the diaphragm opening (the opening is made large) To operate).

<Display when adjusting the aperture of the aperture>
When the adjustment of the opening amount of the opening of the diaphragm mechanism 23 is performed, the processor 10 causes the display unit 14 to display the icon 101 a (or 101 b) via the display control unit 13 in order to make it easy to understand the adjustment state of the opening amount. Display (see FIG. 3).

  For example, when the aperture amount of the diaphragm mechanism 23 is minimum, an image as shown in FIG. 3A is displayed on the display unit 14. At this time, the subject 102 a, the background 103 a, and the icon 101 a are displayed on the display unit 14. In the icon 101a, an annular ring (double circle) in which the inner circle is displayed small is displayed so as to indicate a state in which the aperture opening is at a minimum. The circles that make up this annulus are concentric circles.

  From this state, when the user touches the vicinity of the icon 101a with two fingers to perform a pinch out operation, an image as shown in FIG. 3B is displayed on the display unit 14. At this time, an annular ring (double circle) in which the inner circle is displayed larger than the state in FIG. 3A is displayed on the display unit 14 as the icon 101b. In the state of FIG. 3B, an image is displayed when the image is taken with the aperture opening reduced, so the object 102a is clear, but the background 103a is unclear. As described above, the opening amount of the aperture opening corresponds to the opening amount corresponding to the icon 101a (or 101b). That is, when the circle inside the annular icon is small (in the case of the icon 101a in FIG. 3A), the size of the opening becomes smaller and the depth of field becomes deeper, and the inside of the annular icon When the circle of is large (in the case of the icon 101b in FIG. 3B), the size of the opening becomes large and the depth of field becomes shallow.

  From the state shown in FIG. 3 (b), when the area near the icon 101b is touched with two fingers to perform pinch-in operation, the circle inside the icon 101b gradually becomes smaller, and an image as shown in FIG. 3 (a) Will be displayed on the display unit 14. The circle inside the annular icon 101a (or 10b) changes continuously or intermittently according to the opening amount.

  The pinch-in operation and the pinch-out operation in the above description may be replaced by voice operations such as "dark" or "bright" voices by the user.

  That is, the camera module control unit 21 operates the blade drive unit 22 according to the operation by the pointing tool such as a finger on the touch panel 12 of the portion where the annular icon is displayed, and the size of the opening of the diaphragm mechanism 23 Adjust the Alternatively, the camera module control unit 21 operates the blade drive unit 22 according to the sound acquired by the microphone 17 to adjust the size of the opening of the diaphragm mechanism 23. That is, in the smartphone 1 according to the present embodiment, the processor 10 and the camera module control in response to an operation (touch operation) by a pointing tool such as a finger on the touch panel 12 and an intuitive operation such as voice input (voice operation) to the microphone 17. The portion 21 operates the blade drive portion 22 to adjust the size of the opening of the diaphragm mechanism 23. In this specification, even a user who has not operated the smartphone 1 can perform operations such as touch operation, voice operation, gesture operation and line-of-sight operation (line-of-sight input) that can be immediately understood by the user's instinct It is called "intuitive operation".

<S130>
As described above, after adjusting the aperture of the aperture mechanism 23, the processor 10 detects whether the user has performed a shooting operation (S130). The shooting operation by the user may be an operation via the touch panel 12, a voice operation via the microphone 17, or any other operation. In addition, the photographing operation may be performed without the user performing the operation on the touch panel 12 and the voice operation via the microphone 17. When the photographing operation by the user is not performed (N in S130), the user's operation on the touch panel 12 or the detection of the voice input of the user by the microphone 17 is repeatedly performed (S120).

<S140>
When a shooting operation by the user is detected (Y in S130), the processor 10 causes the imaging device 24 to perform shooting via the camera module control unit 21. The processor 10 stores the acquired image in the memory 15 when the imaging is completed.

<S150>
Next, the processor 10 previews the captured image on the display unit 14 via the display control unit 13 (S150), and ends the camera mode (S160).

  As described above, in the smartphone 1 according to the present embodiment, the size of the diaphragm opening can be controlled by providing the diaphragm mechanism 23, and the display control unit 13 controls the display unit 14 to display the diaphragm opening. Display an image (for example, an icon) for adjusting the size. Then, the camera module control unit 21 controls to adjust the size of the opening of the diaphragm mechanism 23 according to the operation by the pointing tool such as a finger on the touch panel 12 of the portion where the image (for example, icon) is displayed. It is configured. Thereby, in the smartphone 1 of the present embodiment, the user can adjust the size of the aperture opening intuitively by the touch operation. As a result, the user can adjust the depth of field with a simple operation, and it is possible to selectively capture an image in which the background of the subject is blurred or an image in which the background of the subject is clear. In addition, the user can adjust the size of the opening with a simple operation to capture an image of desired brightness.

  Further, in the smartphone 1 according to the present embodiment, since an annular image (icon) formed of two concentric circles is used as an image (icon) for adjusting the size of the opening of the diaphragm mechanism 23, The user can easily confirm that the size of the aperture opening is adjusted. As a result, the user can more intuitively adjust the aperture opening.

  Further, in the smartphone 1 of the present embodiment, the size of the opening of the diaphragm mechanism 23 is reduced according to the pinch-in operation of the user, and the size of the opening of the diaphragm mechanism 23 is increased according to the pinch-out operation. Do. Therefore, the user can make the adjustment of the diaphragm opening more intuitively.

  Further, the smartphone 1 according to the present embodiment includes the microphone 17 for acquiring surrounding (user's) voices, and adjusts the size of the opening of the diaphragm mechanism 23 according to the voice acquired by the microphone 17. It works like this. As a result, the user can adjust the depth of field at the time of shooting with a simple operation, and it is possible to selectively shoot an image in which the background of the subject is blurred or an image in which the background of the subject is clear.

<2. Modified example>
Next, modifications of the above embodiment will be described. In the following description of the modification, only configurations and operations different from the embodiment will be described, and the description of the same contents as the embodiment will be omitted.

  FIG. 4 is a flowchart showing the photographing process in the smartphone 1 of the present modification. In the present modification, the configuration of the smartphone 1 is the same as the configuration of the embodiment, but the operation is partially different. Specifically, the slide bar 111a (or 111b) is displayed on the display unit 14 instead of the icon 101a (or 101b) in the embodiment. In the flowchart of the photographing process of the present modification shown in FIG. 4, compared with the process of the embodiment, the user's operation (S120) is replaced with the user's operation of the slide bar (S125), and the subsequent aperture opening is The adjustment process is replaced (S121 to S124 are replaced by S126 and S127).

<S125>
When the camera mode is activated (S100) and the image of the subject is displayed on the display unit 14 (S110), the processor 10 causes the display unit 14 to adjust the size of the opening of the diaphragm mechanism 23a. (Or 111b) is displayed to detect an operation on the touch panel 12 by the user.

<S126>
When the processor 10 detects an operation of raising the slide bar on the touch panel 12, the processor 10 drives the diaphragm mechanism 23 via the camera module control unit 21 and the blade drive unit 22 to close the diaphragm opening (the opening is reduced) To operate).

<S127>
On the other hand, when the processor 10 detects an operation to lower the slide bar on the touch panel 12, the processor 10 drives the diaphragm mechanism 23 via the camera module control unit 21 and the blade drive unit 22 to open the diaphragm opening (opening Operate to increase

<Display when adjusting the aperture of the aperture>
As in the embodiment, when the adjustment of the opening amount of the opening of the diaphragm mechanism 23 is performed, in order to make it easy to understand the adjustment state of the opening amount, the processor 10 transmits the slide bar to the display unit 14 via the display control unit 13.

  For example, when the aperture amount of the diaphragm mechanism 23 is minimum, an image as shown in FIG. 5A is displayed on the display unit 14. At this time, the subject 102 a, the background 103 a, and the slide bar 111 a are displayed on the display unit 14. In the slide bar 111a, the pointer of the slide bar is displayed at the lowermost position so as to indicate the state in which the aperture opening is at the minimum.

  From this state, when the user touches the vicinity of the slide bar 111a with a finger and performs an operation to raise the pointer of the slide bar, the display unit 14 displays the pointer on the slide bar as shown in FIG. Is displayed at the position of. In the state of FIG. 5B, an image is displayed when the image is taken with the diaphragm opening reduced, so the object 102a is clear, but the background 103a is unclear. As described above, the opening amount of the diaphragm opening becomes the opening amount corresponding to the slide bar 111a (or 111b). That is, when the pointer of the slide bar is positioned at the top (in the case of the slide bar 111a in FIG. 5A), the size of the opening becomes smaller and the depth of field becomes deeper, and the pointer of the slide bar Is at the lower position (in the case of the slide bar 111b in FIG. 5B), the size of the opening becomes large and the depth of field becomes shallow.

  When the user touches the vicinity of the slide bar 111b with a finger from the state shown in FIG. 5 (b) to lower the pointer of the slide bar, as shown in FIG. 5 (a), the slide bar pointer is at the lower position. Will be displayed on. The pointer of the slide bar 111a (or 111b) changes continuously or intermittently according to the opening amount.

  In the smartphone 1 of the present modification, the slide bar 111a (and 111b) is used as an image for adjusting the size of the opening of the diaphragm mechanism 23. Therefore, the user confirms how the size of the diaphragm opening is adjusted. It can be easy to do. As a result, the user can more intuitively adjust the aperture opening.
