(First embodiment)
With reference to FIGS. 3, 8, and 9, the horizontal posture assist function of the camera according to the embodiment of the present invention will be described. FIG. 3 is an image diagram showing an example of horizontal posture assist for the camera (imaging device 1) according to the embodiment of the present invention.

  A line perpendicular to the gravitational direction 200a is defined as a horizontal reference 100a, and an intersection point between the optical axis of the photographing lens 2 of the camera and the imaging surface of the image sensor 10 is defined as an origin 0. At this time, a line extending from the origin 0 in the longitudinal direction of the image sensor 10 is a camera horizontal line 100b, and a line extending from the origin in the short direction of the image sensor is a camera vertical line 200b.

  In the example of this embodiment, the horizontal posture of the camera is a posture in which the horizontal reference 100a and the camera horizontal line 100b are parallel in the case of horizontal position shooting. In the case of vertical position shooting, the horizontal reference 100a and the camera vertical line 200b are parallel to each other. The camera rotation angle means an angle formed by the horizontal reference 100a and the camera horizontal line 100b in the case of horizontal position shooting, and an angle formed by the horizontal reference 100a and the camera vertical line 200b in the case of vertical position shooting.

  Further, as a configuration example of audio output, audio output from the right audio output unit 41 and the left audio output unit 42 is referred to as audio output 51 and audio output 52.

  In the present embodiment, an example will be described in which two or more audio output units are used to assist different operations of the left and right ears of the user to assist the horizontal posture determination operation in shooting with the camera.

  FIG. 9 is a flowchart showing an operation example of the camera according to the first embodiment of the present invention. The flowchart of FIG. 9 illustrates a processing procedure executed by the system control unit 14 by controlling each processing block. This is realized by developing a program stored in a ROM in a memory 25 of the system control unit 14 in a RAM and executing it by a CPU (not shown).

  First, in step S001, a voice assist operation is started.

  Next, in step S003, the horizontal posture of the imaging apparatus 1 is determined. First, for example, an acceleration sensor as the posture detection unit 32 detects the gravitational direction 200a from the gravitational acceleration. Subsequently, the posture determination unit 33 determines whether the camera is rotating in the clockwise direction or the counterclockwise direction around the origin 0 with respect to the horizontal reference 100a. Calculate how many times.

  When the horizontal posture determination step S003 is performed, the process proceeds to step S004, and the sound generation unit 31 generates assist sound according to the information obtained in the determination step of step S003. Based on the calculation result of the posture determination unit 33, the voice generation unit 31 generates an assist voice to be transmitted to the user. The assist sound is, for example, an electronic continuous sound or a buzzer sound that emphasizes a certain frequency that is easy to hear even when mixed with other sounds.

  Here, in FIG. 3, the camera is rotated in the direction of the rotation direction 61. In order to set the camera in a horizontal posture, the user needs to perform an operation of rotating in a rotation direction 62 opposite to the rotation direction 61. Therefore, in order to quickly and intuitively convey the operation instruction to the user, an assist sound that can be heard from the direction in which the camera is to be rotated, that is, from the rotation direction 62 side is generated. When an external device for sound output such as headphones is used, since the L / R corresponds to the left and right ears of the user, for example, by increasing the output sound of the right sound output unit 41, the user can Can recognize that the sound is being played.

  In step S005, the generated assist voice is output. For example, stereo (stereo) sound is output using the stereo sound output unit 30 including the speaker 30 (1) and the speaker 30 (2) illustrated in FIG. In order to increase the effect of the three-dimensional sound, it is preferable that the arrangement intervals of the speakers are separated. Further, an external electronic device 29 connected to the camera via the wired I / F 28, for example, a headphone can be used as the output unit. An external electronic device 29 connected to the camera via the wireless I / F 27, for example, the smart phone 80 illustrated in FIG. 8 may be used as the output unit. In addition to using the speaker 81 provided in the smart phone 80, an external device connected to the smart phone, such as the headphone 40, may be used. In addition, since the effect of the example of this embodiment is demonstrated by transmitting different sounds to the left and right ears of the user, the headphones corresponding to the user's left and right ears and the left and right audio output units one-on-one are output means. When used as, it is easier to obtain the effect.

  In the positional relationship between the user and the camera illustrated in FIG. 8, when the camera is in the posture illustrated in FIG. 3, in order to set the horizontal posture 301, the user wants to recognize that sound is being played from the left side. For this purpose, the output sound 52 of the L-side sound output unit 42 may be made larger than the output sound 51 of the R-side sound output unit 41 or only the output sound 52 of the L-side sound output unit 42 may be output.

  As one of audio controls for quickly and intuitively transmitting the camera rotation angle to the user, for example, volume control may be performed. The volume is increased as the rotation angle of the camera increases with the horizontal posture set to volume 0. When the user listens to the output assist voice and correctly performs the rotation operation, the sound volume is reduced, so that the user can recognize that the rotation operation is performed in the correct direction. However, the change in volume does not necessarily have to be linear. In order to obtain an accurate horizontal posture, it is desirable to increase the sensitivity with respect to a volume change near a rotation angle of 0 ° that needs to be finely adjusted.

  Note that the volume control is taken up as one example of the voice control for quickly and intuitively transmitting the rotation angle to the user, but is not limited thereto. As alternatives to the sound volume, sound field localization, frequency, tone color, pitch, interval between discontinuous sounds, and the like may be considered, and the sound volume may be changed according to the rotation angle in the same manner as the sound volume. However, in any case, in the horizontal state, it is preferable to know that the camera is in a horizontal posture without performing a rotation operation. Therefore, it is preferable that the volume is 0 dB, that is, the sound can be always determined by the user as an absolute value.

  In step S007, the output of the assist voice is stopped.

  In step S008, it is determined whether or not the photographing is finished. If the shooting is continued, the operation returns to the start of operation and the level is determined again, and the voice assist is continued. If the user gives an instruction to end shooting in step S008, the operation ends in step S009.

  The pronunciation of the assist voice in the present invention may be troublesome when the user is shooting in a scene that does not require a horizontal posture. Therefore, it is preferable that a system that allows the user to freely turn on and off the pronunciation of the assist voice according to the present invention is applied to the camera. For example, when the “landscape shooting” mode, which often uses horizontal posture detection, is linked to the present invention, and the user rotates the mode dial 4 to switch the shooting mode to the “landscape shooting” mode, the assist voice according to the present invention is used. The pronunciation function may be included.

  As described above, it is possible to provide an imaging apparatus that can intuitively convey the attitude of the imaging apparatus to the user by voice and can immediately perform a rotation operation for obtaining a horizontal attitude.

(Second Embodiment)
As a second embodiment of the present invention, an example of voice assist corresponding to four horizontal postures will be described. In addition, the part which performs the same process as embodiment mentioned above is shown with the same symbol, and abbreviate | omits description. In the present embodiment, a configuration of a horizontal posture assist button (not shown) is added to the imaging apparatus 1, or a function of horizontal assist operation is assigned to an existing operation member.

  As described above, in the camera, the posture determination unit 33 determines the horizontal posture in accordance with the posture detected by the posture detection unit 32. As a determination procedure, first, the direction 102 and the direction 104 with the camera horizontal line 100b as an axis in FIGS. 3 and 4 and the direction 101 and the direction 103 with the camera vertical line 200b as an axis, which direction is the most gravitational direction 200a. Calculate closeness. From the calculation result, one horizontal posture is determined from four horizontal postures of a horizontal posture 301, a horizontal posture 302, a horizontal posture 303, and a horizontal posture 304.

  FIG. 7 is an example of a correspondence table of each direction and each horizontal posture in the first and second embodiments of the present invention. The camera has a function of rotating the captured image by a multiple of 90 ° according to the determination result of the horizontal posture. Accordingly, it is desirable that the horizontal posture assist according to the example of the present invention corresponds not only to the horizontal posture 301 representing the camera normal position but also to the four horizontal postures including the remaining three horizontal postures.

  FIG. 5 is a graph showing the relationship between the rotation angle and volume of the camera according to the first embodiment of the present invention. It is a graph showing the example of the relationship between the rotation angle of the camera which concerns on 4 types of horizontal attitude | positions, and a sound volume based on 1st Embodiment. From the graph, in the first embodiment of the present invention, the volume in the horizontal posture is set to 0 dB, and the volume is increased as the rotation angle of the camera is increased. For example, the rotation angle of + 45 ° with respect to the horizontal posture 301 is It can be seen that the volume is maximum. However, the same angle becomes a point at which the sound volume becomes maximum even with the horizontal posture 304 as a reference. Further, since the directions to rotate are opposite in the horizontal posture 301 and the horizontal posture 304, if the determination of the horizontal posture is switched at 45 ° which is an intermediate angle between the direction 103 and the direction 104, an assist voice is output. Will switch between left and right at maximum volume. This switching may occur many times, especially when handling the camera in the shooting preparation stage. A method is also conceivable in which a certain rotation angle range centering on an intermediate angle of each of the direction 101, the direction 102, the direction 103, and the direction 104 is silenced. However, as described above, since it is desirable that the horizontal posture has a volume of 0 dB, that is, silence, it is not preferable to set a silent range in a posture other than the horizontal posture.

  FIG. 10 is a flowchart showing an operation example of the camera according to the second embodiment of the present invention. The flowchart in FIG. 10 illustrates a processing procedure executed by the system control unit 14 controlling each processing block. This is realized by developing a program stored in a ROM in a memory 25 of the system control unit 14 in a RAM and executing it by a CPU (not shown).

  After the operation of step S001 starts, when the user presses the horizontal posture assist button in step S002a, the system control unit 14 recognizes that the horizontal posture assist button has been pressed. In response to this, the horizontal assist operation is started.

  Subsequently, in step S003, the horizontal posture of the camera 1 is determined based on the posture information of the camera 1 obtained by the posture detector 32. In this embodiment, four horizontal postures of a horizontal posture 301, a horizontal posture 302, a horizontal posture 303, and a horizontal posture 304 are selected depending on which of the direction 101, the direction 102, the direction 103, and the direction 104 is closest to the gravity direction 200a. One of the postures is determined as the current horizontal posture. For example, when the horizontal posture assist button is pressed while the direction 102 is closest to the gravity direction 200 a, the horizontal posture is determined as the horizontal posture 302.

  When the horizontal posture determination step S003 is performed, the process proceeds to step S004, where the sound generation unit 31 generates assist sound according to the information obtained by the posture detection unit 32.

  In step S005, an assist voice is output from the output means. Here, while the user continues to press the horizontal posture assist button (during the horizontal assist operation), the assist sound is always output unless the camera is in the horizontal posture. Further, after the horizontal posture is determined, the determination of the horizontal posture is not performed at all while the user continues to press the horizontal posture assist button (during the horizontal assist operation). That is, while the horizontal posture assist button is continuously pressed, the change in the vertical position / horizontal position is not recognized, and the horizontal assist is continued based on the vertical position / horizontal position determined in step S003.

  If the user stops pressing the horizontal posture assist button in step S006, the output of the assist voice is stopped in step S007.

  After the user stops pressing the horizontal posture assist button, it is determined in step S008 that the shooting has ended. If the photographing has not ended, the process returns to step S002a again to determine whether or not the horizontal posture assist button has been pressed. If the user gives an instruction to end shooting in step S008, the operation ends in step S009.

  FIG. 6 shows an example of a graph representing the relationship between the rotation angle and volume of the camera according to the second embodiment of the present invention. While the horizontal posture assist button is pressed, the horizontal posture of the camera is limited to one. Therefore, it is possible to set a volume curve in which the output of the assist voice that reaches the user's ear does not switch between right and left within an angle range in which the rotation angle from the horizontal posture is 180 °.

  The above-described horizontal posture assist button may be assigned as an additional function to a button having another function in the existing camera configuration. For example, SW1 in which AE processing and AF processing are performed and shooting conditions are set is a button that is highly likely to be pressed during shooting, and functions are compatible even when a horizontal posture assist function is additionally assigned. Also in the second embodiment, the point where the output of the assist sound that reaches the user's ear is switched between right and left occurs when the rotation angle is 180 ° from the horizontal posture. Since it is rare to rotate the camera by 180 ° while pressing SW1, which is a preparatory operation immediately before shooting, the inversion of the horizontal assist voice hardly occurs, and the effect of this function is sufficiently exhibited. In addition, when this function is assigned to SW1, the horizontal assist can be made to function by the same operation as the normal photographing operation.

  As described above, according to the present embodiment, it is possible to realize a horizontal posture assist function without causing inversion of the assist sound even when the vertical / horizontal position of the camera changes. .

  The above is a description of a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiment within the scope of the technical idea of the present invention, and is adapted as appropriate according to the target circuit form. What to do. For example, the camera described as the imaging device in the above-described embodiment can be applied to a digital still camera or a digital video camera.

  Further, the present invention can be embodied as a system, apparatus, method, computer program, or recording medium, for example. Specifically, the present invention can be applied to a system composed of a plurality of apparatuses even if it is realized by one apparatus. May be. Each means of the imaging apparatus according to the present embodiment and each step of the imaging apparatus control method can also be realized by operating a program stored in a memory of a computer or the like.
