Description

  The present invention relates to an imaging / recording apparatus that captures and records a subject to be imaged, a portable terminal, a method for controlling the imaging / recording apparatus, an imaging / recording apparatus control program, and a computer-readable recording medium on which the program is recorded.

  2. Description of the Related Art Conventionally, there are photographing and recording devices that photograph and record a subject, such as a digital camera and a digital movie camcorder. This digital camera or digital movie camcorder determines the length and breadth when the moving image or still image (image) is displayed by using the longitudinal direction or short direction information of the viewfinder when shooting. Configuration 1).

  Specifically, for example, when the longitudinal direction of the viewfinder is displayed as the horizontal direction, the longitudinal direction of the viewfinder at the time of photographing is stored as the longitudinal direction of the image data of the photographed image. When the stored image data is displayed, the longitudinal direction of the image data is displayed as the horizontal direction.

  In the case of the recording / recording apparatus having the above-described configuration, when the user captures an image with the photographing apparatus rotated 90 degrees from a predetermined position, the image viewed by the user through the viewfinder at the time of photographing is such that the longitudinal direction of the viewfinder is It becomes an image of the direction.

  In this case, the longitudinal direction of the stored image data is the vertical direction of the subject, and in the displayed image, the vertical direction of the subject is the horizontal direction.

  However, until the user displays the stored image data, the relationship between the direction in which the stored data is recorded and the direction in which the user was viewing at the time of shooting is broken (that is, when displayed) It may not be recognized that the vertical direction of the subject is displayed sideways.

  Then, in order for the user to correctly display the image data in which the vertical direction of the subject is the horizontal direction, it is necessary to rotate the display device (or the display unit of the photographing and recording device) by 90 degrees.

  This will be described in more detail with reference to FIG. FIG. 10 is an explanatory diagram illustrating a display example of a photographed image when the photographing recording apparatus is photographed by being rotated 90 degrees from a predetermined value.

  As shown in FIG. 10, when shooting is performed with the shooting and recording apparatus 1002 rotated 90 degrees from a predetermined angle during shooting, the viewfinder 1003 displays the longitudinal direction of the viewfinder 1003 as the top-to-bottom direction of the subject 1001. . Then, the longitudinal direction of the viewfinder 1003 is stored as the longitudinal direction of the image data, and the displayed image is in a state in which the vertical direction of the subject 1001 is the horizontal direction.

  In order to solve this problem, Patent Document 1 discloses a technique for storing images in the same direction regardless of the rotation angle of the digital camera at the time of shooting.

  However, in the configuration of Patent Document 1, the direction of the stored image data is aligned regardless of the user's intention. This will be described below with reference to FIGS. FIG. 11 is an explanatory diagram showing image data to be stored when the technique described in Patent Document 1 is used.

  Image data A, C, and D shown in FIG. 11 are image data that is stored when the longitudinal direction of the viewfinder of the digital camera is taken in the horizontal direction. Further, the image data B is image data stored when shooting is performed with the longitudinal direction of the viewfinder of the digital camera set to the vertical direction.

  Image data A, C, and D are recorded as image data that is horizontally long. On the other hand, the image data B is recorded as vertically long image data.

  This causes the following problems. That is, when image data A, B, C, and D are displayed on a display device that displays in landscape orientation, the image data stored in landscape orientation (image data A, C, and D) fits in the display device, but the image is saved in portrait orientation. Data (image data B) is displayed with a lack of top and bottom.

  This point will be described with reference to FIG. FIG. 12 is a diagram illustrating how image data stored in landscape orientation and image data stored in portrait orientation are displayed on the display device, respectively.

  As shown in FIG. 12, image data stored in landscape orientation (here, image data C is shown as an example) is displayed in its entirety without being cut off in the display area 1201 because the display area 1201 of the display device 1202 is landscape orientation. Is done. On the other hand, when the image data B stored in the vertically long format is to be displayed by using the display area 1201 as much as possible, the image data B is cut off from the top and bottom. In addition, when the top and bottom are displayed, the left and right display areas are not used sufficiently.

  As described above, when the vertically long image data and the horizontally long image data are mixed, there is a problem that the image data cannot be displayed sufficiently.

  Also, there is a type that switches the longitudinal direction of the viewfinder to the vertical direction or the horizontal direction of the image data to be stored depending on the image size to be photographed.

  According to this, without being aware of the user, the storage direction changes when the longitudinal direction of the viewfinder becomes the vertical direction of the stored image data or the horizontal direction.

  In order to solve this problem, there is a configuration in which an icon indicating the upward direction of stored image data is displayed (Configuration 2).

  A configuration for displaying an icon indicating the upward direction of stored image data will be described with reference to FIG. FIG. 13 is an explanatory diagram of a configuration for displaying an icon indicating an upward direction of stored image data.

  In the case of shooting example A in FIG. 13, an icon 1301 indicating which direction in the image displayed in the viewfinder is upward is displayed in the lower right portion of the viewfinder above the storage direction, that is, as the stored image data. It is displayed.

  In the shooting example A, when the longitudinal direction of the viewfinder is set to the horizontal direction, the icon 1301 indicating the upper storage direction indicates the left direction in the viewfinder. Therefore, when photographing in this state, the left direction of the subject shown in the viewfinder is the upward direction of the stored image data. When the image data when the image is taken in this state is displayed, the left direction of the subject shown in the viewfinder is displayed as the upward direction of the display device.

In the shooting example B, when the longitudinal direction of the viewfinder is set in the horizontal direction, the icon 1301 indicating the storage direction is pointing upward in the viewfinder. Therefore, when shooting in this state, the upward direction of the subject shown in the viewfinder is the upward direction of the stored image data. When shooting data obtained when shooting in this state is displayed, the upward direction of the subject shown in the viewfinder is displayed as the upward direction of the display device.
JP 2001-119665 A (published on April 27, 2001)

  However, the conventional configuration causes the following problems. That is, in the above-described conventional configuration 1, the sky direction when the subject to be photographed is displayed is different from the sky direction of the image when the image data obtained by photographing the subject is displayed. Even so, the user cannot recognize this.

  Therefore, only when the user displays the stored image data, the celestial direction of the displayed subject is different from the celestial direction of the image when the image data obtained by photographing the subject is displayed. Recognize and be confused.

  Further, in the conventional configuration 2, since the icon indicating the upward direction is small and always displayed, the effect of alerting the user is small. Therefore, the user often does not recognize in which direction the image data of the captured image is stored until the captured image is displayed.

  The present invention has been made in view of the above-mentioned problems, and its purpose is an image when a sky direction when a photographed subject is displayed and image data obtained by photographing the subject are displayed. It is intended to realize a photographing and recording device or the like that allows the user to recognize when the direction of the sky is different.

  In order to solve the above problems, an imaging / recording apparatus according to the present invention, in an imaging / recording apparatus that captures and records a subject to be imaged, captures the subject by tilt detection means for detecting the tilt of the subject device. Subject direction determining means for determining a subject direction indicating the celestial direction of the subject on the display screen when the obtained image data is displayed from tilt information indicating the tilt detected by the tilt detecting means; and the image data A celestial direction determining means for determining whether or not the image data direction indicating the celestial direction of the display image on the display screen when is displayed matches the subject direction determined by the subject direction determining means, and And a notifying means for notifying a result determined by the sky direction determining means.

  Also, the control method of the photographing / recording apparatus according to the present invention is a control method of the photographing / recording apparatus for photographing and recording a subject to be photographed, wherein a tilt detecting step for detecting a tilt of the own device and photographing the subject. A subject direction determination step for determining a subject direction indicating the sky direction of the subject on the display screen when the image data obtained in this manner is displayed from tilt information indicating the tilt detected in the tilt detection step; A celestial direction determining step for determining whether or not the image data direction indicating the celestial direction on the display screen when the image data is displayed matches the subject direction determined by the subject direction determining means; A notification step of notifying the result determined in the direction determination step.

  According to the above configuration and method, the subject direction indicating the celestial direction of the subject on the display screen when the image data obtained by photographing the subject is displayed is determined from the detected tilt of the own device. Then, it is determined whether or not the image data direction indicating the top direction of the display image on the display screen when the image data is displayed matches the determined subject direction, and the result is notified.

  As a result, the user can recognize the result indicating whether or not the subject direction and the image data direction match. Therefore, the image data can be stored in a state where the user recognizes whether or not the subject direction and the image data direction match. Accordingly, it is possible to prevent image data having a subject direction different from the image data direction from being stored without the user's recognition.

  In addition, since the user can recognize the case where the subject direction and the image data direction are different, even when the top direction of the subject is displayed in a direction different from the top direction of the image data when the image data is displayed, the user can There is no confusion.

  In the photographing / recording apparatus according to the present invention, the notifying unit may notify only a result determined by the celestial direction determining unit that the subject direction does not match the image data direction. Good.

  According to the above configuration, the notifying unit notifies only the result determined by the celestial direction determining unit that the subject direction and the image data direction do not match. A case where the image data direction does not match can be recognized more accurately.

  Further, the notification means only needs to notify when the subject direction and the image data direction do not match. Therefore, the notification means can be realized by a simple device such as sounding a buzzer or turning on a light.

  In the photographing and recording apparatus according to the present invention, a focus adjustment unit that adjusts the focus on the subject, and detection of the completion of the focus adjustment by the focus adjustment unit is output to the notification unit. And an end detection unit that performs notification when the detection signal is input from the end detection unit.

  According to said structure, a alerting | reporting means will alert | report, when the detection signal which shows that the focus adjustment means complete | finished the focus adjustment is input. Thus, since the notification is performed after the focus adjustment is completed, the notification can be performed immediately before the user performs photographing. Therefore, the user can recognize that the subject direction is different from the image data direction immediately before shooting, and reconsider whether to continue shooting or to change the subject direction to the state where the image data direction matches. Can do.

  In the photographing and recording apparatus according to the present invention, a rotatable display unit, display unit rotation information acquisition means for acquiring rotation information indicating in which direction and how much the display unit is rotated, and display unit rotation information acquisition Image data direction adjusting means for adjusting the image data direction according to the rotation information of the display unit acquired by the means, and the sky direction determining means is adjusted by the subject direction and the image data direction adjusting means. It may be determined whether or not the image data direction matches.

  According to said structure, a display part rotation information acquisition means acquires the rotation information which shows how much the display part is rotating to which direction. Then, the image data direction adjustment unit adjusts the image data direction from the rotation information acquired by the display unit rotation information acquisition unit. Then, the sky direction determination means determines whether or not the adjusted image data direction matches the subject direction.

  Accordingly, it is possible to cope with a case where the image data direction cannot be correctly recognized due to the rotation of the display unit, and it cannot be accurately determined whether or not the subject direction matches the image data direction. That is, even if the display unit is rotated, the image data direction can be recognized in consideration of the rotation of the display unit, so that it is possible to accurately determine whether the subject direction and the image data direction match. .

  Therefore, even when the display unit rotates, it can be accurately determined whether or not the subject direction and the image data direction match.

  Even a portable terminal equipped with the above-described photographing and recording apparatus can achieve the above-described effects.

  The photographing and recording apparatus may be realized by a computer. In this case, a control program for the photographing and recording apparatus that causes the computer to realize the photographing and recording apparatus by operating the computer as each of the above-described means, and A computer-readable recording medium on which is recorded also falls within the scope of the present invention.

  As described above, the photographing and recording apparatus according to the present invention includes the inclination detecting means for detecting the inclination of the own apparatus and the top of the subject on the display screen when the image data obtained by photographing the subject is displayed. An object direction determining means for determining a subject direction indicating a direction from inclination information indicating an inclination detected by the inclination detecting means, and an image indicating a celestial direction of a display image on the display screen when the image data is displayed. A celestial direction determining unit that determines whether or not the data direction and the subject direction determined by the subject direction determining unit match, and an informing unit that notifies the result determined by the celestial direction determining unit. It is a configuration.

  In addition, the control method of the photographing and recording apparatus according to the present invention includes an inclination detecting step for detecting the inclination of the own apparatus, and the top of the subject on the display screen when image data obtained by photographing the subject is displayed. A subject direction determination step for determining a subject direction indicating a direction from tilt information indicating a tilt detected in the tilt detection step, and an image indicating a top direction of a display image on the display screen when the image data is displayed. A method including a celestial direction determination step for determining whether or not the data direction and the photographic subject direction determined by the photographic subject direction determination means match, and a notification step for notifying the result determined in the celestial direction determination step. is there.

  As a result, the user can recognize the result indicating whether or not the subject direction and the image data direction match. Therefore, the image data can be stored in a state where the user recognizes whether or not the subject direction and the image data direction match. Accordingly, it is possible to prevent image data having a subject direction different from the image data direction from being stored without the user's recognition.

  In addition, since the user can recognize the case where the subject direction and the image data direction are different, even when the top direction of the subject is displayed in a direction different from the top direction of the image data when the image data is displayed, the user can There is no confusion.

[Embodiment 1]
One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram of a portable terminal (photographing / recording apparatus) 1 according to the present embodiment. The mobile terminal 1 has a camera function. Then, when the mobile terminal 1 performs photography, the sky direction (subject direction) when the subject to be photographed is displayed, and the sky direction of the display image when the image data obtained by photographing the subject is displayed. If it is determined that the (image data direction) is different, the user is notified. Thereby, it is possible to prevent the image data direction from being stored in a state different from the subject direction without the user's recognition.

  Specifically, the reason why the subject direction is different from the image data direction will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of a direction in which the mobile terminal 1 or the digital camera is held when the user performs shooting. As shown in FIG. 3, it is conceivable that the user holds the mobile terminal 1 and the digital camera in various directions. Depending on the direction in which the subject is held, the subject direction and the image data direction do not match.

  Although the present embodiment will be described using the mobile terminal 1, the photographing and recording apparatus is not limited to this. Any device capable of photographing and recording may be used, and for example, a digital camera or a digital movie camcorder may be used.

  Moreover, although the portable terminal 1 has a function as a mobile phone, this function is performed using a known technique, and the description thereof is omitted.

  As illustrated in FIG. 1, the mobile terminal 1 includes an imaging unit 11, a control unit 13, an operation receiving unit 14, an inclination detection unit 15, a storage unit 16, a display unit 17, and a notification unit 18. The control unit 13 includes an operation signal acquisition unit 101, a mismatch notification setting unit 102, a tilt information acquisition unit (tilt detection unit) 103, a subject direction determination unit (subject direction determination unit) 104, and a mismatch determination unit (top direction determination unit). ) 105 and a discrepancy notifying unit (notifying means) 107.

  The imaging unit 11 includes a lens and a photosensitive sensor such as a charge coupled device (CCD), and the subject captured by the lens is signaled by the CCD and used as image data. Then, the signalized image data is transmitted to the display unit 17. The image data may be processed or the image may be corrected so that the image can be displayed on the display unit 17 before being transmitted to the display unit 17.

  The image data is stored in the storage unit 16 in accordance with a user instruction.

  The control unit 13 notifies the user when the celestial direction of the subject to be photographed is different from the celestial direction of the image data when the image data obtained by photographing the subject is stored. Details of the control unit 13 will be described later.

  The operation reception unit 14 receives an instruction from the user and transmits a signal having the received content to the operation signal acquisition unit 101. Examples of the operation receiving unit 14 include a shutter button, a focusing button, a button key to which numbers, alphabets, and the like are assigned, a cross key indicating a direction, and the like.

  The inclination detection unit 15 detects the inclination of the mobile terminal 1. Then, the inclination detection unit 15 transmits inclination information indicating the detected inclination to the inclination information acquisition unit 103. Examples of the inclination detection unit 15 include a gravity sensor and a mechanical pendulum.

  The storage unit 16 stores image data captured by the mobile terminal 1, a direction in which the image data is stored, settings of the mobile terminal 1, and the like. An example of the storage unit 16 is a flash memory.

  The display unit 17 displays an image taken by the imaging unit 11. The display unit 17 may be realized by any device as long as it can display information. Specific examples include a liquid crystal display device and an organic EL (electroluminescence) display. It is done. Moreover, if only the image which the imaging part 11 image | photographed is displayed, it may be an optical thing like a sight glass.

  The notification unit 18 notifies the user of the match / mismatch between the subject direction and the image data direction. The notification unit 18 may be realized by any means that can notify the user, and specific examples include a speaker and an LED (light emitting diode). In addition, the notification unit 18 may output information to be notified to the display unit 17 described above and display the notification content on the display unit 17. Further, an LCD (liquid crystal display) may be provided separately from the display unit 17 and the notification content may be displayed on the LCD.

  In the present embodiment, it is assumed that only the case where the subject direction does not match the image data direction is notified.

  Next, the control unit 13 will be described in more detail. As described above, the control unit 13 includes the operation signal acquisition unit 101, the mismatch notification setting unit 102, the tilt information acquisition unit 103, the subject direction determination unit 104, the mismatch determination unit 105, and the mismatch notification unit 107.

  The operation signal acquisition unit 101 acquires a signal indicating an instruction from the user received by the operation reception unit 14. If the acquired signal indicates a setting as to whether or not to perform mismatch notification, notification setting information indicating that is transmitted to the mismatch notification setting unit 102. If the acquired signal indicates the activation of the camera function, the camera activation information to that effect is transmitted to the tilt information acquisition unit 103.

  When receiving the notification setting information from the operation signal acquisition unit 101, the mismatch notification setting unit 102 sets the notification of the mismatch between the subject direction and the image data direction in the mobile terminal 1 with the setting content indicated by the notification setting information. Set to. Then, the set content is stored in the storage unit 16.

  When the tilt information acquisition unit 103 receives the camera activation information from the operation signal acquisition unit 101, the tilt information acquisition unit 103 acquires the tilt information from the tilt detection unit 15. Then, the acquired tilt information is transmitted to the subject direction determination unit 104.

  The subject direction determination unit 104 determines the celestial direction of the subject in the image when the image data is displayed, from the tilt information received from the tilt information acquisition unit 103. Then, the subject direction information indicating the subject direction which is the celestial direction of the determined subject is transmitted to the mismatch determination unit 105.

  More specifically, for example, when the tilt detection unit 15 is a mechanical pendulum, a state where the pendulum is not tilted is set to “0”. If the mobile terminal 1 is tilted 45 degrees to the right at the time of shooting, the direction of the subject on the display screen is 45 degrees to the left compared to the direction of the subject on the display screen when the mobile terminal 1 is not tilted. The direction is inclined. At this time, the direction inclined 45 degrees to the left is determined as the subject direction.

  The mismatch determination unit 105 determines whether or not the subject direction indicated by the subject direction information received from the subject direction determination unit 104 matches the image data direction stored in the storage unit 16. If it is determined that the subject direction and the image data direction do not match, the mismatch information indicating the mismatch is transmitted to the mismatch notification unit 107.

  For example, in the case where a mechanical pendulum is provided and the top direction of the image taken with the pendulum not tilted matches the image data direction, the image data direction is “0 degree”. Then, as described above, when the mobile terminal 1 is photographed with 45 degrees tilted to the right, the subject direction is “45 degrees left”. The mismatch determination unit 105 compares the image data direction “0 degrees” with the subject direction “45 degrees left” to determine whether they match.

  Upon receiving the mismatch information from the mismatch determination unit 105, the mismatch notification unit 107 notifies the notification unit 18 that there is a mismatch. In addition, a clock unit (not shown) may be provided so as to notify only for a predetermined time.

  In the above description, the notification is made when the subject direction and the image data direction do not match, but it is determined whether or not the subject direction and the image data direction match. In the case of non-coincidence, it may be informed that there is a mismatch.

  Next, the flow of processing for performing notification when the subject direction and the image data direction are different in the mobile terminal 1 will be described with reference to FIG. FIG. 2 is a flowchart showing a flow of processing for performing notification when the subject direction and the image data direction are different in the mobile terminal 1.

  When the operation reception unit 14 receives an instruction to activate the camera function from the user and the operation signal acquisition unit 101 acquires a signal indicating activation of the camera (S201), the mismatch determination unit 105 is set to notify the mismatch. (S202). If the setting is to notify the mismatch (YES in S202), the mismatch determination unit 105 determines whether the subject direction matches the image data direction (S203). If the subject direction and the image data direction do not match (NO in S203), the mismatch notification unit 107 notifies the notification unit 18 that there is a mismatch (S204).

  Next, when there is a change in the tilt information acquired by the tilt information acquisition unit 103 from the tilt detection unit 15 (YES in S205), the mismatch determination unit 105 again determines whether the subject direction and the image data direction match. Is determined (S207). If the subject direction matches the image data direction (YES in S207), the mismatch notification unit 107 cancels the notification of mismatch (S208). In addition, when there is no change in the tilt information (NO in S205) and a predetermined time has elapsed (YES in S206), the mismatch notification unit 107 cancels the notification of mismatch (S208). On the other hand, if the subject direction does not match the image data direction (NO in S207), the process returns to S205.

  When the shutter is pressed (YES in S209), shooting is performed (S210), and the process ends.

  On the other hand, if it is not set to notify the mismatch (NO in S202), the process proceeds to S209. If the subject direction matches the image data direction (YES in S203), the process proceeds to S209.

  With the above configuration, when shooting with the mobile terminal 1, the user is notified that the subject direction and the image data direction are different. Therefore, it is possible to prevent the subject direction and the image data direction from being different without the user's recognition. Therefore, when the user displays the image data, it is possible to prevent the user from being confused by displaying an image that is not recognized by the user and whose subject direction is not aligned.

  This will be specifically described with reference to FIG. FIG. 3 is a diagram illustrating the relationship between the subject direction and the image data direction when shooting is performed using the mobile terminal 1 of the present embodiment. Here, it is assumed that the longitudinal direction of the display unit 17 is the vertical direction of the stored image data.

  When the subject 31 shown in FIG. 3 is photographed using the mobile terminal 1, the mobile terminal 1 is placed vertically as shown in the holding method A, and the display unit 17 is on the left as shown in the holding method B. It is possible to hold the mobile terminal 1 sideways so that the display unit 17 is on the right side as shown in the way C.

  When shooting with the holding method A, the subject direction is up like the image data 321. When shooting with the holding method B, the subject direction is right and shooting with the holding method C as shown in the image data 322. Like the image data 323, the subject direction is stored on the left. Therefore, when the image data 321, 322, and 323 are displayed, the image data 321 has the subject direction up, the image data 322 has the subject direction on the right, and the image data 323 has the subject direction on the left. Therefore, if the user does not recognize that the image data is stored in this way, the user will be confused when the image data is displayed.

  According to the present embodiment, when shooting with the holding method B and the holding method C, the user is notified that the subject direction and the image data direction are different. Therefore, when the subject direction and the image data direction are different, the user recognizes that. Therefore, it is possible to prevent the user from being confused when the image data is displayed.

  The relationship between the subject direction and the image data direction when the same shooting is performed with a digital camera will be described with reference to FIG. FIG. 4 is a diagram illustrating the relationship between the subject direction and the image data direction when shooting is performed using a digital camera. Here, it is assumed that the short direction of the display unit is the vertical direction of the stored image data.

  When the subject 41 shown in FIG. 4 is photographed using the digital camera 40, the shutter button 42 is held up as shown in the holding method D, and the shutter button 42 is placed on the right as shown in the holding method E. It may be possible to hold the shutter button 42 to the left as shown in the holding method F.

  When shooting with the holding method D, the subject direction is up like the image data 421. When shooting with the holding method E, the subject direction is left and shooting with the holding method F like the image data 422. Like the image data 423, the subject direction is stored on the right. Therefore, when the image data 321, 322, and 323 are displayed, the image data 321 has the subject direction up, the image data 322 has the subject direction on the right, and the image data 323 has the subject direction on the left.

  Further, in the present embodiment, when the subject direction and the image data direction are different, only the user is notified. Therefore, when saving image data of a photographed subject, the direction of the image data is not automatically switched, and the longitudinal direction of the image data does not become irregular in length and width without being recognized by the user. Therefore, for example, when image data is displayed on a horizontally long screen, the image data is stored on a horizontally long image data display screen, but the vertically long image data is not displayed with a lack of top and bottom.

  In the present embodiment, it is determined whether or not the subject direction and the image data direction coincide with each other when the camera function is activated. It may be due to.

  For example, a focus adjustment unit (focus adjustment unit, end detection unit) 106 that automatically adjusts the focus is provided, and information indicating that the focus adjustment unit 106 has finished adjusting the focus is transmitted to the inclination information acquisition unit 103, and the subject direction And the image data direction may be determined. By determining whether the subject direction and the image data direction coincide with each other using the automatic focus adjustment instruction as a trigger, there are the following advantages.

  In other words, since automatic focus adjustment instructions are often issued immediately before shooting, if the automatic focus adjustment instruction is used as a trigger, does the subject direction and image data direction match immediately before shooting? Will be made. Therefore, while the camera function is activated and the angle of the camera is being considered, it is possible to prevent the subject direction and the image data direction from being determined to be consistent with each other and to prevent the notification of the mismatch.

  A processing flow in the case of including an automatic focus adjustment function and determining whether the subject direction and the image data direction coincide with each other using an automatic focus adjustment instruction as a trigger will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of processing when it is determined whether the subject direction and the image data direction coincide with each other using an automatic focus adjustment instruction as a trigger. In FIG. 5, steps for performing the same processing as in FIG. 2 are denoted by the same step numbers as in FIG. 2, and description thereof is omitted.

  When it is determined whether the subject direction and the image data direction match using an instruction for automatic focus adjustment as a trigger, if it is set to perform mismatch notification (YES in S202), whether or not an instruction for automatic focus adjustment has been given. Is determined (S601). If there is an instruction to automatically adjust the focus (YES in S601), the mismatch determination unit 105 determines whether or not the subject direction matches the image data direction (S203). The subsequent steps are the same as those in FIG.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those shown in the first embodiment are given the same reference numerals, and explanation thereof is omitted.

  In the portable terminal (photographing / recording apparatus) 2 according to the present embodiment, the display unit 17 is rotatable with respect to the casing in which the operation receiving unit 14 is provided.

  A case where the user performs shooting using the portable terminal 2 in which the display unit 17 is rotatable will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of the direction in which the mobile terminal 2 is held and the rotation direction of the display unit 17 when the user performs shooting. As shown in FIG. 8, the user can hold the mobile terminal 1 and the digital camera in various directions. Depending on the direction in which the subject is held, the subject direction and the image data direction do not match.

  In general, in the case of an imaging device in which the display unit rotates, the image data direction changes depending on whether the display unit is not rotated or rotated. As a result, there is a possibility that the image data direction recognized by the photographing apparatus is different from the actual image data direction.

  This will be specifically described with reference to FIG. FIG. 9 shows the direction of the subject, the direction of the image capturing device, the direction of the stored image data, the direction recognized by the image capturing device as the image data direction, and the actual image data direction in the image capturing device whose display unit rotates. FIG.

  In FIG. 9, A and C do not rotate the display unit of the photographing apparatus. A shows a case where the photographing apparatus is in a vertical state, and C shows a case where photographing is performed with the photographing apparatus in a horizontal state. B and D rotate the display unit of the photographing apparatus 90 degrees clockwise. B shows a case where the photographing device is in a vertical state, and D shows a case where the photographing device is in a horizontal state.

  As shown in FIG. 9, in the case of A, the image data direction recognized by the photographing apparatus is upward, and the actual image data direction is also upward. In the case of B, the image data direction recognized by the photographing apparatus is upward, and the actual image data direction is rightward. In the case of C, the image data direction recognized by the photographing apparatus is the left direction, and the actual image data direction is also the left direction. In the case of D, the image data direction recognized by the photographing apparatus is the left direction, and the actual image data direction is the upward direction.

  As described above, when the display unit is rotated, the image data direction recognized by the photographing apparatus is different from the actual image data direction. Therefore, when it is determined whether or not the subject direction and the image data direction match, in reality, A and D match and B and C do not match, but only A matches. B, C, and D are determined to be inconsistent.

  In the present embodiment, the above-described adverse effects are prevented by recognizing the rotation direction and rotation angle of the display unit. As shown in FIG. 7, the mobile terminal 2 according to the present embodiment includes a rotation function unit 19 and a display unit rotation information acquisition unit (display unit rotation information acquisition unit, image data direction adjustment) in addition to the configuration of the mobile terminal 1. Means) 108 is provided. FIG. 7 is a block diagram of mobile terminal 2 according to the present embodiment.

  The rotation function unit 19 rotates the display unit 17 and transmits display unit rotation information indicating the rotation direction and rotation angle of the display unit 17 to the display unit rotation information acquisition unit 108.

  The display unit rotation information acquisition unit 108 adjusts the image data direction stored in the storage unit 16 from the display unit rotation information acquired from the rotation function unit 19, and sends information indicating the adjusted image data direction to the mismatch determination unit 105. Send.

  Specifically, in the example provided with the mechanical pendulum described above, if the image data direction stored in the storage unit 16 is “0” and the display unit rotation information is “90 degrees to the right”, the image The data direction is set to “90 degrees to the right” and transmitted to the mismatch determination unit 105.

  Then, the mismatch determination unit 105 uses the adjusted image data direction acquired from the display unit rotation information acquisition unit 108 when determining whether or not the subject direction and the image data direction match. Thus, it can be determined whether or not the subject direction and the image data direction are exactly the same.

  The case of FIG. 9B described above will be described. In the case of B in FIG. 9, since the image data direction recognized by the imaging apparatus in the past is different from the actual image data direction, whether or not the subject direction and the image data direction are exactly the same is determined. I could not judge.

  In the present embodiment, since the display unit 17 is considered to be rotated 90 degrees to the right, the mismatch determination unit 105 has the image data direction to the right of the image data direction stored in the storage unit 16. It can be recognized that the rotation direction is 90 degrees in the direction. Therefore, the image data direction recognized by the mobile terminal 2 matches the actual image data direction, and the mismatch determination unit 105 accurately determines whether or not the subject direction and the image data direction match. be able to.

  It should be noted that it may be difficult to detect the tilt of the mobile terminals 1 and 2 when shooting in the sky or on a desk. In such a situation where accurate detection is not possible, there may be provided means for not performing notification or temporarily preventing notification. As a determination method when such accurate detection cannot be performed, for example, if the inclination detection unit 15 is a gravity sensor, the determination can be made by measuring the elevation angle.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the embodiments can be obtained by appropriately combining technical means disclosed in different embodiments. The form is also included in the technical scope of the present invention.

The display unit rotation information acquisition unit 108 may be configured by hardware logic, or may be realized by software using a CPU as follows.

  In other words, the mobile terminals 1 and 2 include a CPU that executes instructions of a control program that realizes each function, a ROM (read only memory) that stores the program, a RAM (random access memory) that expands the program, the program and A storage device (recording medium) such as a memory for storing various data is provided. An object of the present invention is a recording medium in which program codes (execution format program, intermediate code program, source program) of a control program for portable terminals 1 and 2 which are software for realizing the functions described above are recorded in a computer-readable manner. Can also be achieved by reading the program code recorded on the recording medium and executing it by the computer (or CPU or MPU (microprocessor unit)).
