Description

  The present invention relates to a photographing apparatus that detects a vertical posture and a horizontal posture of a photographing apparatus, and acquires information in a vertical direction of a photographed image from the detected vertical and horizontal postures of the photographing apparatus.

  Conventionally, as this type of photographing apparatus, for example, there is a camera disclosed in Patent Document 1. This camera is equipped with posture detection means for detecting the posture of the camera. At the time of shooting, the posture detection means detects the posture state of the camera at the time of shooting, and the detection result is obtained as captured image data obtained at the time of shooting. At the same time, it is recorded on a recording medium. When the captured image data is reproduced, the posture state of the camera at the time of reproduction is detected, and it is determined whether the detection result matches the posture state at the time of photographing recorded on the recording medium. If the result of this determination does not match, image rotation processing is performed on the captured image data so that the captured image data is displayed in the correct direction. Therefore, when an image shot with the camera is played back, if the image shot in the vertical position and the image shot in the horizontal position are mixed, the top and bottom of the image shot in the vertical position is displayed correctly. The

  However, in the conventional camera disclosed in Patent Document 1, the camera attitude detection means detects the camera attitude based on gravity. For this reason, if the photographer is shooting with the camera facing the sky, or shooting with the camera facing the ground, and the shooting optical axis of the camera is directed vertically, The position cannot be detected accurately, and the attitude detection means detects the slight tilt of the camera facing the vertical direction based on the gravity, and erroneous information about the vertical position or the horizontal position of the captured image is acquired.

The present invention has been made to solve such problems,
Vertical and horizontal posture detecting means for detecting the vertical posture and horizontal posture of the photographing device;
Vertical information acquisition means for acquiring vertical information of the captured image from the vertical and horizontal postures of the photographing device detected by the vertical and horizontal posture detection means;
In an imaging apparatus comprising information adding means for adding information in the vertical direction acquired by the vertical information acquiring means to a captured image,
Vertical detection means for detecting that the photographing optical axis in the direction in which the subject light enters the photographing apparatus is directed in the vertical direction;
When the vertical detection means detects that the photographing optical axis is directed in the vertical direction, invalid means for invalidating the vertical and horizontal posture detection processing by the vertical and horizontal posture detection means ,
Vertical information automatic acquisition means for automatically acquiring vertical information of a captured image by detecting a specific pattern of a subject when it is detected by the vertical detection means that the photographing optical axis is directed in the vertical direction When,
When the vertical detection means detects that the photographing optical axis is directed in the vertical direction, the vertical information manual acquisition means for acquiring the vertical information of the captured image based on the operation on the operation member;
When the vertical detection means detects that the photographing optical axis is directed in the vertical direction, either the vertical information automatic acquisition means or the vertical information manual acquisition means is selected based on the direction in which the subject light is incident in the vertical direction. The photographing apparatus is configured to include selection means for acquiring information in the vertical direction of the photographed image .

  According to this configuration, when the vertical detection unit detects that the photographing optical axis is directed in the vertical direction, the vertical and horizontal posture detection processing by the vertical and horizontal posture detection unit is disabled by the invalidation unit. Therefore, when it is detected that the photographing optical axis is directed in the vertical direction, the vertical / horizontal posture detection unit is activated, and the vertical / vertical information acquisition unit performs shooting from the vertical / horizontal posture of the photographing apparatus detected by the vertical / horizontal posture detection unit. Incorrect information in the vertical direction of the image is not acquired. Therefore, the information addition unit does not add erroneous vertical information acquired by the vertical information acquisition unit to the captured image. For this reason, a direction different from the vertical direction of the actual captured image is acquired as the vertical direction of the captured image due to a slight inclination of the capturing device oriented in the vertical direction, and the information adding unit corrects this erroneous vertical direction. Information is not added to the captured image. As a result, when it is detected that the photographing optical axis is directed in the vertical direction, it is possible to prevent erroneous detection in which erroneous information in the vertical direction of the photographed image is acquired.

Also, according to this configuration, when the vertical detection unit detects that the photographing optical axis is directed in the vertical direction, the selection unit selects either the vertical information automatic acquisition unit or the vertical information manual acquisition unit. Information in the vertical direction of the captured image is acquired. For this reason, when it is detected that the photographing optical axis is directed in the vertical direction, depending on the photographing situation of whether the subject light is incident from the sky direction or from the ground direction, Either one of the vertical information manual acquisition means can acquire the information in the vertical direction of the photographed image, and the photographing can be performed with convenience.

According to the photographing apparatus of the present invention, as described above, when it is detected that the photographing optical axis is directed in the vertical direction, erroneous detection in which erroneous information in the vertical direction of the photographed image is acquired is prevented. be able to. In addition, either the vertical information automatic acquisition unit or the vertical information manual acquisition unit can acquire the information in the vertical direction of the captured image, so that shooting can be performed with high convenience.

A flash 7 is provided on the upper right side when viewed from the front of the camera body 2 to ensure brightness when the subject is dark.

  FIG. 1B is a rear perspective view showing an outline of the external appearance of the digital camera 1. In the figure, the same parts as those in FIG. 1A are denoted by the same reference numerals, and the description thereof is omitted.

  A monitor 11 is provided on the back of the camera body 2. The monitor 11 is made of a TFT (Thin Film Transistor) liquid crystal and displays various types of information such as a through image for confirming the composition and shooting information, and reproduces and displays the shot image. A touch panel 12 having a touch panel function is disposed on the surface of the monitor 11. A touch operation on the monitor 11 by the photographer is detected by the touch panel 12.

  On the right side of the monitor 11, a zoom button 13 and a cross button 14 are arranged. The zoom button 13 is operated when the captured image displayed on the monitor 11 is enlarged or reduced. The cross button 14 includes direction keys for detecting operation directions such as up and down directions and left and right directions.

In addition, these buttons can be substituted by a touch panel operation of the monitor 11 on the menu screen displayed on the monitor 11.

  FIG. 2 is a block diagram illustrating an outline of an electric circuit configuration of the digital camera 1.

  The digital camera 1 includes a CPU (Central Processing Unit) 21, a nonvolatile memory 22 including an EEPROM (Electrically Erasable Programmable Lead Only Memory), and a buffer memory 23 including a RAM (Random Access Memory). Yes. The nonvolatile memory 22 stores a control program that is referred to when the CPU 21 performs various controls. In accordance with a control program stored in the non-volatile memory 22, the CPU 21 controls each part of the circuit using the buffer memory 23 as a temporary storage work area and operates various device functions of the digital camera 1.

  Light from the subject is taken into the digital camera 1 through the lens 3 constituting the optical system. The subject light captured in the digital camera 1 projects a subject image on the imaging surface 25 a of the imaging unit 25. The imaging unit 25 includes a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), and the like, and the subject image formed on the imaging surface 25a of the imaging unit 25 is converted into an analog imaging signal. The converted image signal is converted into a digital signal by the A / D converter 26. The image processing unit 27 acquires the imaging signal converted into a digital signal by the A / D conversion unit 26 via the bus 28, and performs image processing such as white balance processing and gamma correction on the acquired imaging signal. The image data of the photographed image is generated. The image data generated by the image processing unit 27 is subjected to compression processing by the CPU 21 and temporarily stored in the buffer memory 23, and is attached to and detached from a slot (not shown) via the I / F unit 29. Is recorded in the memory card 30 constituting the.

  A release button 5 is connected to the CPU 21. When the release button 5 is half-pressed, the autofocus function is activated to move the lens 3, and when the release button 5 is fully pressed, a shutter (not shown) is opened at a preset shutter speed, and the subject image is captured by the imaging unit 25. The surface 25a is exposed for a predetermined time so that the subject is photographed. The CPU 21 causes the monitor 11 to display the subject imaged on the imaging surface 25a of the imaging unit 25 as a through image. When a touch operation performed on the display area of the monitor 11 is detected by the touch panel 12, a touch operation detection signal is output from the touch panel 12 and information input by the touch operation is sent to the CPU 21.

  The CPU 21 is connected to a vertical / horizontal sensor 24a and a vertical sensor 24b. The vertical / horizontal sensor 24a detects a two-dimensional direction indicating whether the posture of the digital camera 1 is the horizontal position shown in FIG. 3A or the vertical position shown in FIG. The vertical sensor 24b detects a two-dimensional direction in which the photographing optical axis Z of the digital camera 1 is the horizontal direction shown in FIG. 4A or the vertical direction shown in FIG. 3 and 4, the upper direction of the drawing is the sky direction, and the lower direction is the ground direction. In these drawings, the same parts as those in FIG. . The vertical / horizontal sensor 24a and the vertical sensor 24b detect the posture of the digital camera 1 by detecting, for example, the rolling position of the roller stored in the storage body, and provide information on the detected posture of the digital camera 1. Tell the CPU 21. The vertical / horizontal sensor 24a constitutes vertical / horizontal posture detecting means for detecting the vertical posture and horizontal posture of the digital camera 1. The vertical sensor 24b constitutes a vertical detection unit that detects that the photographing optical axis Z in the direction in which the subject light enters the digital camera 1 is directed in the vertical direction.

  When the digital camera 1 is taken horizontally as shown in FIG. 4A, the orientation of the digital camera 1 is the horizontal position shown in FIG. 3A by the vertical / horizontal sensor 24a or shown in FIG. 3B. Whether it is a vertical position is detected, and the CPU 21 adds the vertical direction information of the image to the captured image from the detection result, and records it in the memory card 30. At the time of reproduction, the image is automatically rotated and reproduced and displayed on the monitor 11 according to the vertical direction information read from the memory card 30 so as to be in the normal position when viewed from the user. The CPU 21 constitutes vertical information acquisition means for acquiring the vertical information of the captured image from the vertical and horizontal posture of the digital camera 1 detected by the vertical and horizontal sensor 24a, and captures the vertical information acquired by the vertical information acquisition means. An information adding means for adding to an image is configured.

  Further, when the digital camera 1 is photographed toward the ground as shown in FIG. 4B, the roller in the storage body constituting the vertical / horizontal sensor 24a rolls due to a slight inclination of the digital camera 1. However, if the image is taken in the vertical position but is taken in the horizontal position, the vertical / horizontal sensor 24a may erroneously detect. Therefore, in the present embodiment, the CPU 21 cancels the posture detection by the vertical / horizontal sensor 24a when the photographing optical axis Z of the digital camera 1 is oriented vertically as shown in FIG. Prevent false detection of 24a. When the vertical sensor 24b detects that the photographing optical axis Z is directed in the vertical direction, the CPU 21 constitutes invalid means for invalidating the vertical / horizontal posture detection processing by the vertical / horizontal sensor 24a.

  In addition, the CPU 21 has a function of performing image analysis from a specific pattern such as a person's face, fingers and characters (for example, numbers and alphabets) imaged by the imaging unit 25 and determining the vertical direction of the captured image. Yes. For example, the vertical direction of the captured image is determined by performing pattern analysis with the direction indicated by the photographer's finger or the direction in which the photographed person's face, characters, etc. are in the normal position as the upward direction of the captured image. To do. When the vertical sensor 24b detects that the photographing optical axis Z is directed in the vertical direction, the CPU 21 automatically acquires information in the vertical direction of the photographed image by detecting a specific pattern of the subject. It constitutes an automatic information acquisition means.

  FIG. 5 is a rear view of the digital camera 1 when the touch panel is operated. In the figure, the same parts as those in FIG.

  The touch panel 12 includes a through image display area 12a for displaying a through image and a direction designation area 12b for designating the vertical direction of the captured image. When it is desired to determine the upward direction in the photographed image of the through image displayed on the touch panel 12, by touching the finger 40 on the upper side of the through image that is desired to be in the upward direction among the four sides of the direction designation area 12b. The vertical direction of the captured image can be specified. Therefore, even when the photographing optical axis Z of the digital camera 1 is oriented in the vertical direction and the vertical direction of the photographed image cannot be determined by the vertical / horizontal sensor 24a and the vertical sensor 24b, the vertical direction of the image is designated by the touch panel 12. , You can easily specify the vertical direction of the captured image. When the vertical sensor 24b detects that the photographing optical axis Z is directed in the vertical direction, the CPU 21 manually acquires the vertical information of the photographed image based on an operation on the touch panel 12 that is an operation member. Configure the acquisition means.

  Instead of the direction designation area 12b for designating the vertical direction of the photographed image, a dedicated icon for designating the vertical direction of the photographed image is displayed on the touch panel 12, and the photographed image is touched to operate the dedicated icon. It is good also as a structure which can designate the up-down direction.

  Further, instead of the touch panel 12, a cross button 14 may be used to specify the vertical direction of the captured image. For example, by pressing the cross button 14 in the direction corresponding to the upward direction of the through image displayed on the monitor 11, the upward direction of the captured image is determined.

  In general, the digital camera 1 including the touch panel 12 on the monitor 11 has a function of focusing on the touched portion by touching the touch panel 12. In order to prevent conflict with this, for example, only when the digital camera 1 is facing the vertical phrase, the above-described direction designation area 12b is displayed on the monitor 11, and the displayed direction designation area 12b is touched. Thus, the vertical direction of the captured image may be designated. In addition, a configuration for switching between the above-described function of focusing on the touched location and the function of specifying the vertical direction of the captured image depending on whether the touch panel 12 is touched and released for a long time is used. Also good.

  FIG. 6 is a flowchart illustrating an outline of processing for acquiring information in the vertical direction of a captured image, which is performed by the CPU 21 of the digital camera 1.

  In step (hereinafter referred to as S) 1, the CPU 21 determines whether or not the photographing optical axis Z of the digital camera 1 is oriented in the vertical direction as shown in FIG. 4B based on the detection result of the vertical sensor 24 b. To do. When the photographing optical axis Z of the digital camera 1 is not oriented in the vertical direction and the determination in S1 is “NO”, the CPU 21 indicates the orientation of the digital camera 1 by the vertical / horizontal sensor 24a in S2 as shown in FIG. Whether it is the horizontal position or the vertical position shown in FIG. 3B is detected. In step S3, the direction of the digital camera 1 detected by the vertical / horizontal sensor 24a is adopted to determine the vertical direction of the captured image.

  On the other hand, when the photographing optical axis Z of the digital camera 1 is oriented in the vertical direction and the determination in S1 is “YES”, in S4, the CPU 21 disables the function of the vertical / horizontal sensor 24a. Next, in S <b> 5, the CPU 21 tries to detect a pattern of a human face, fingertip, character, or the like from the image of the subject imaged by the imaging unit 25. Next, in S6, the CPU 21 determines whether or not a pattern such as a face, fingertip, or character has been detected. If a pattern such as a face, fingertip, or character cannot be detected and the determination in S6 is “NO”, in S7, the CPU 21 inputs a direction to specify the vertical direction of the captured image by operating the touch panel 12 described above with reference to FIG. It is determined whether or not there is. If no direction input is performed by the touch panel 12 and the determination in S7 is “NO”, in S8, the CPU 21 assumes that there is no direction information, and ends the process of acquiring the vertical information of the captured image. .

  On the other hand, if a pattern such as a face, fingertip, or character is detected and the determination in S6 is “YES”, the CPU 21 determines the direction in which the up and down direction of the captured image is designated from the pattern such as the face, fingertip, or character in S9. The calculated direction is provisionally determined as a temporary direction. Next, in S10, it is determined whether or not there is a direction input for designating the vertical direction of the captured image by the operation of the touch panel 12 described above. When the orientation input of the touch panel 12 is not performed and the determination in S10 is “NO”, the CPU 21 officially detects the orientation calculated from the detection of the pattern of the face, fingertip, character, etc., which is provisionally determined in S9 in S11. Adopted as the orientation, the vertical direction of the captured image is determined. On the other hand, when the orientation of the touch panel 12 is input in S7 or S10 and the determination in S7 or S10 is “YES”, the CPU 21 adopts the detected orientation based on the input of the touch panel 12 in S12, and the vertical direction of the captured image. To decide.

  According to the digital camera 1 according to this embodiment, when the vertical sensor 24b detects that the photographing optical axis Z is directed in the vertical direction in the process of FIG. The vertical / horizontal posture detection processing by the sensor 24a is invalidated in S4. Therefore, when it is detected in S1 that the photographing optical axis Z is directed in the vertical direction, the vertical / horizontal sensor 24a is activated, and the vertical / horizontal information acquisition means detects the vertical / horizontal posture of the digital camera 1 detected by the vertical / horizontal sensor 24a. From this, incorrect information in the vertical direction of the captured image is not acquired. Therefore, the information addition unit does not add erroneous vertical information acquired by the vertical information acquisition unit to the captured image. Therefore, a direction different from the vertical direction of the actual captured image is acquired as the vertical direction of the captured image due to the slight inclination of the digital camera 1 oriented in the vertical direction, and the erroneous vertical direction is acquired by the information adding unit. Is not added to the captured image. As a result, when it is detected that the photographing optical axis Z is directed in the vertical direction, it is possible to prevent erroneous detection in which erroneous information in the vertical direction of the photographed image is acquired.

  Further, according to the digital camera 1 according to the present embodiment, when the vertical sensor 24b detects in S1 that the photographing optical axis Z is directed in the vertical direction, the vertical / horizontal posture detection processing by the vertical / horizontal sensor 24a is performed by the invalid means. After being invalidated in S4, the specific pattern of the subject is detected in S5 by the vertical information automatic acquisition means, and the vertical information of the captured image is automatically acquired. For this reason, when it is detected in S1 that the photographing optical axis Z is directed in the vertical direction by the vertical sensor 24b, the vertical information is automatically acquired even if the detection processing of the vertical / horizontal sensor 24a is invalidated in S4 by the invalidating means. By the means, the specific pattern of the subject is detected in S5, whereby the vertical information of the captured image is accurately acquired.

  Further, according to the digital camera 1 according to the present embodiment, when the vertical sensor 24b detects in S1 that the photographing optical axis Z is directed in the vertical direction, the vertical / horizontal posture detection processing by the vertical / horizontal sensor 24a is performed by the invalid means. The information in the vertical direction of the captured image is acquired in S12 based on the operation on the touch panel 12 by the vertical information manual acquisition unit, invalidated in S4. For this reason, when the vertical sensor 24b detects that the photographing optical axis Z is directed in the vertical direction, even if the detection process of the vertical / horizontal sensor 24a is invalidated by the invalid means, the vertical information manual acquisition means performs the photographing. Information on the up and down direction of the photographed image is acquired based on the user's operation on the touch panel 12. In addition, by operating the photographer on the touch panel 12, information in the vertical direction of the photographed image can be added to the photographed image in accordance with the photographer's preference.

  In the above embodiment, the CPU 21 prioritizes the vertical information manual acquisition unit over the vertical information automatic acquisition unit, and as described above, prioritizes the detection direction of S12 by the operation of the touch panel 12, and the vertical direction of the captured image. It was determined. However, when it is detected by the vertical sensor 24b that the photographing optical axis Z is directed in the vertical direction, the vertical information automatic acquisition means or the vertical information manual acquisition means is based on the direction in which the subject light is incident in the vertical direction. The CPU 21 may be configured as a selection unit that causes one of the information to acquire the vertical direction information of the captured image. In this case, for example, when the digital camera 1 is placed on the stage with the lens 3 facing upward and the photographer cannot operate the touch panel 12 or the cross button 14, the photographing optical axis Z is vertically adjusted by the vertical sensor 24 b. The vertical information automatic acquisition means is selected by detecting that the direction in which the subject light is incident in the vertical direction is the sky side, and the vertical direction of the captured image is selected by the vertical information automatic acquisition means described above. Get information about. Further, for example, when the digital camera 1 is held by the photographer with the lens 3 facing down and the photographer can operate the touch panel 12, the cross button 14, etc., the photographing optical axis Z is set in the vertical direction by the vertical sensor 24b. The vertical information manual acquisition means is selected by detecting that the direction in which the subject light is directed and is incident on the ground side in the vertical direction, and information on the vertical direction of the captured image is selected by the vertical information manual acquisition means described above. To get.

  According to the digital camera 1 having such a configuration, when the vertical sensor 24b detects that the photographing optical axis Z is directed in the vertical direction, the selection unit performs the vertical information automatic acquisition unit or the vertical information manual acquisition unit. In either case, information in the vertical direction of the captured image is acquired. For this reason, when it is detected that the photographing optical axis Z is directed in the vertical direction, the vertical information automatic acquisition means is adapted to the photographing situation of whether the subject light is incident from the sky direction or the ground direction. Alternatively, either one of the vertical information manual acquisition means can acquire the information in the vertical direction of the photographed image, and the photographing can be performed with convenience.

  In the present embodiment, the vertical and horizontal sensors 24a that detect the vertical and horizontal postures of the digital camera 1 in two axial directions and the vertical sensors 24b that detect the vertical and horizontal directions of the digital camera 1 in two axial directions are used. The posture of the digital camera 1 was detected using two sensors. However, instead of the vertical / horizontal sensor 24a and the vertical sensor 24b, a single triaxial sensor that detects all directions in the triaxial direction, an acceleration sensor for detecting a camera shake of a photographer having the digital camera 1, and the like, A configuration for detecting the attitude of the digital camera 1 may also be used. Further, the configuration may be such that the vibration is applied by hitting the side of the digital camera 1 and the vertical direction of the captured image is determined with the direction and position of the vibration applied as the upward direction of the captured image. Even with such a configuration, the same operational effects as the above-described embodiment can be obtained.

  In the above embodiment, the case where the photographing apparatus of the present invention is applied to a digital camera has been described. However, the present invention can also be applied to other photographing apparatuses such as a video camera and a camera built in a mobile phone. . Even when the present invention is applied to such a photographing apparatus, the same effects as the above-described embodiment can be obtained.
