Description

  The present invention relates to an imaging apparatus having display means capable of displaying a stereoscopic image.

  With the recent widespread use of stereoscopic video viewing environments, suitable stereoscopic video imaging devices are required. A human recognizes a visually recognized object as a three-dimensional image by synthesizing an image visually recognized by the right eye and an image visually recognized by the left eye. That is, this is realized by the difference between the image visually recognized by the right eye and the image visually recognized by the left eye by visually recognizing the object from different angles of the right eye and the left eye.

  For this reason, it is generally necessary for a stereoscopic video imaging device to record video information corresponding to left and right parallaxes. Further, in order to visually recognize a stereoscopic image, it is necessary to independently transmit video information corresponding to the recorded left and right parallax to the left and right eyes. For this reason, various display devices described below have been proposed as means for visually recognizing a stereoscopic video from a right-eye video having a right-eye parallax and a left-eye video having a left-eye parallax.

  Conventionally, as a display device for displaying stereoscopic video, a liquid crystal shutter system that alternately displays right-eye video and left-eye video and separates left and right by a shutter synchronized with the display video, right-eye video and left-eye video polarization direction There are different polarization methods, such as a polarization method that uses a polarizing filter and an anaglyph method that uses red and blue glasses. Further, as a display device that displays a stereoscopic image with the naked eye, a left-eye image is displayed on every other row of pixels of the liquid crystal display panel, a right-eye image is displayed on every other row of pixels, and the left-eye and right-eye images are displayed. A lenticular lens system that distributes the output image from the light emitted from the pixels in one column and the light emitted from the pixels in the other column to the left and right eyes of the display observer. Alternatively, a parallax barrier method in which a viewer's left eye and right eye are observed through a parallax barrier in which a plurality of transmissive portions and light shielding portions parallel to pixel rows of a liquid crystal display panel are alternately arranged. In addition, a backlight time-sharing method has been proposed in which the backlight light is alternately divided into the right-eye direction and the left-eye direction in a time-division manner in synchronization with the display switching timing of the right-eye video and the left-eye video. .

  By using such a technique, stereoscopic video display can be realized. However, there is a problem that stereoscopic video is difficult to view unless conditions for viewing (for example, viewing distance and viewing angle) are not met. Specific conditions vary depending on the method of stereoscopic video display and the device to be used. In general, the appropriate viewing distance for stereoscopic video display of a small display device is 30 cm to 1 m, and the appropriate viewing angle is generally ± 5 ° in front.

  In such a display device that displays a stereoscopic image, Patent Document 1 is disclosed in which switching control related to stereoscopic image display is performed in accordance with the display screen direction of the display device. This detects the display screen direction (vertical, horizontal) of the display device, changes the alignment direction of the liquid crystal molecules of the parallax barrier panel in accordance with the display screen direction, and is suitable for stereoscopic display. Furthermore, it is switched whether or not to perform stereoscopic video display corresponding to the display screen direction. Further, Patent Document 2 is disclosed in such a display device that displays a stereoscopic image. This is because the reproduction display does not perform the stereoscopic video display when the subject at the time of shooting the stereoscopic video is shot in a state that is inappropriate for visually recognizing the stereoscopic video.

  However, the prior art disclosed in the above-mentioned Patent Document 1 does not mention any device that can change the orientation of the display device, not the display screen direction of the display device. In addition, in the conventional technique disclosed in Patent Document 2 described above, there is no mention of the relationship between the display device and the observer. For example, this is the case of an imaging apparatus that can be opened and closed and rotated with respect to the apparatus main body. The imaging device is provided with a display device for displaying a video being photographed and a reproduced video, and this display device is disposed on the imaging device main body by a hinge part so as to be opened and closed and rotated.

  When the display device is in a normal shooting state facing the photographer side, the photographer is observing the display device, so that the display device is always in a position suitable for viewing a stereoscopic image (appropriate viewing distance, proper viewing distance) Viewing angle). Hereinafter, the position suitable for visually recognizing a stereoscopic image is referred to as “3D appropriate viewing position”. However, in the face-to-face shooting state in which the display device is directed to the subject side, that is, in the same direction as the lens, the person observing the display device is a photographer who takes a selfie or a person who is a subject. It is assumed that it is in a proper position. That is, in the face-to-face shooting state, there are many scenes that are not in the proper 3D visual recognition position. Therefore, there is a problem that it is difficult to visually recognize the video when the video on the display device is confirmed.

  Therefore, an object of the present invention is to provide an imaging device that improves the visibility when confirming the display of a display device capable of displaying a stereoscopic video in a face-to-face shooting state.

  In order to achieve the above object, the configuration of the present invention includes an imaging unit, a main body unit including the imaging unit, and a display unit capable of three-dimensional display that allows a video to be viewed stereoscopically by adding parallax, From the state where the display unit is connected to the main body unit so as to be rotatable, the detection unit detects the position of the display unit relative to the main body unit, and the three-dimensional display is performed by the display unit. When the control unit detects that the display surface of the display unit is in the same direction as the imaging surface of the imaging unit, the control unit controls to switch the display on the display unit to a two-dimensional display. It is characterized by having.

  According to the present invention, in the face-to-face shooting state, the display on the display device capable of displaying a stereoscopic video is switched, so that the visibility when confirming the display video can be improved.

In this embodiment, a video camera is used. However, a digital still camera or the like may be used as long as the video signal can be recorded and reproduced. The lens 202 is a lens unit for capturing a stereoscopic image, and 202R is a first lens that captures a right-eye image, and 202L is a second lens that captures a left-eye image.

  In FIG. 3, reference numeral 109 denotes a display unit which is provided so as to be rotatable with respect to the video camera main body 201 and is capable of displaying a playback video and a captured video. Hereinafter, “2D display” is possible. Reference numeral 302 denotes a hinge unit that rotatably holds the display unit 109 with respect to the video camera main body 201. The display unit 109 can be opened and closed in the direction of arrow A and can be rotated in the direction of arrow B. Hereinafter, the state of FIG. 3 is the normal rotation state, the state where the display unit 109 is closed in the direction of arrow A from the normal rotation state is the normal rotation storage state, and the state of FIG. The state in which 109 is rotated is referred to as a facing state, and the state in which the display unit 109 is closed in the direction of arrow A from the facing state is referred to as an inverted storage state.

  Reference numeral 301 denotes a power button. By pressing the power button, the video camera 201 can be turned on / off.

  An operation of the imaging apparatus configured as described above will be described. The control microcomputer 104 is a central processing unit that controls the entire video camera and performs arithmetic processing. The compressed program stored in the flash memory is decompressed and expanded in the program memory, and the control microcomputer 104 operates according to the program in the program memory.

  The camera signal processing unit 102 performs various kinds of signal processing on the electrical signal sent from the image sensor 101. The image sensor 101 is a photoelectric conversion element for converting an image formed through the lens 202 of the video camera body 201 into an electric signal. The compression / decompression processing method of the video signal processing unit 103 may be a moving image encoding method that compresses and encodes each frame independently, such as Motion JPEG, or may be independent for each frame, such as MPEG. It may be a moving image encoding method that compresses and encodes, compresses and encodes the difference between the preceding and succeeding frames, or predicts and encodes from a plurality of frames.

  Reference numeral 107 denotes a liquid crystal signal processing unit that controls the display unit 109 to display an input video signal. The liquid crystal signal processing unit 107 also includes a 2D3D display switching unit 108 that switches between 3D display and 2D display on the display unit 109. The control microcomputer 104 controls ON / OFF of video display on the display unit 109 and inversion processing of the display video. Reference numerals 106 and 107 denote display unit attitude determination means. In this embodiment, the rotation detection switch 106 and the open / close detection switch 107 are used. Open / close detection switch 107 detects that display 109 has been opened / closed in the direction of arrow A in FIG. 3, and rotation detection switch 106 detects that it has rotated in the direction of arrow B.

  Next, a method for visually recognizing a stereoscopic image on the display unit 109 in this embodiment will be described in detail. In this embodiment, a parallax barrier method is adopted as a method for visually recognizing a stereoscopic image. As shown in FIG. 12, the parallax barrier display unit 109 includes a display panel 109A, a parallax barrier panel 109B, and the like, thereby realizing 3D display.

  The display panel 109A includes a liquid crystal display panel and displays a display image. The parallax barrier panel 109B has the same configuration as the liquid crystal display panel, and controls transmission of light generated by image display on the display panel 109A. Therefore, the parallax barrier panel 109B is configured in the display unit 109 so as to be positioned between the display panel 109A and a person (observer) who views the display screen of the display panel 109A.

  The operation principle of performing 3D display on the display unit 109 having such a configuration will be described with reference to FIGS. 10 and 11. When 3D display is performed using the parallax barrier panel 109B, the parallax of the left eye and the right eye is used. Therefore, when 3D display is performed on the display unit 109, a left-eye image and a right-eye image as shown in FIG. 10 are prepared. The left-eye image and the right-eye image both indicate the same display target, but are shifted in the left-right direction according to the parallax. Here, the left-eye image is an image captured by the second lens 202L of the lens unit 202, and the right-eye image is an image captured by the first lens 202R of the lens unit 202.

  The display panel 109A of the display unit 109 alternately displays the display positions of the pixels constituting the left-eye image and the pixels constituting the right-eye image in the left-right direction. That is, as shown in the lower part of FIG. 10, the pixels constituting the right-eye image are displayed in an odd-numbered column and the pixels constituting the left-eye image are displayed as an even-numbered column. In other words, each of the left-eye image and the right-eye image is arranged in pixels so as to be arranged in every other column (line), and the left-eye image and the right-eye image are displayed so that the lines are staggered. Note that the pattern of the pixel arrangement does not have to be in units of one column, and for example, a line may be constituted by a plurality of pixels. Further, the pixel unit may not be an integer value.

  The display panel 109A displays an image in which the left-eye image and the right-eye image are arranged in a stripe shape in this way. Here, the line composed of pixels of the left-eye image reaches the left eye of the observer, and the line composed of pixels of the right-eye image reaches the observer's right eye. The two images with parallax as shown in FIG. 10 are recognized by the eyes corresponding to each of them. As a result, the images are synthesized in the observer's brain and viewed as a three-dimensional image.

  Here, the parallax barrier panel 109 </ b> B performs an operation of displaying each line in the 3D image in a corresponding eye direction. As described above, since the parallax barrier panel 109B has the same structure as the liquid crystal display panel, the light generated by the image display of the display panel 109A is transmitted by controlling the voltage application to the electrodes corresponding to the respective pixels. Or can be shielded from light. In other words, the barrier pattern on the stripe as shown in FIG. 11 is formed so as to correspond to the line of the 3D image displayed on the display panel 109A.

  Then, as shown in FIG. 12, the left and right pixels displayed on the display panel 109A pass through the transmissive row of the barrier pattern formed on the parallax barrier panel 109B and reach the left and right eyes of the viewer. In order to do this, it is necessary to appropriately control transmission / non-transmission (light shielding) in each stripe (line, column). In this case, the orientation direction of the liquid crystal molecules may be changed by controlling the applied voltage for each stripe (line, column). This display control varies depending on the distance from the observer's eyes to the display unit 109 and the interval between the observer's right eye and left eye. In the case of 2D display, either the left-eye image or the right-eye image is displayed on the display panel 109A, and all lines are made transparent in the transmission / non-transmission (light shielding) control of the parallax barrier panel 109B. Is possible.

  Next, a method for controlling the switching of the video displayed on the display unit 109 in the first embodiment of the present invention will be described. FIG. 4 is a flowchart showing a switching control procedure of a video displayed on the display unit 109 in the embodiments of the first and second aspects of the invention.

  This process is executed by the control microcomputer 104. In FIG. 4, when the power is turned on, the posture of the display unit 109 is determined by the open / close detection switch 107 and the rotation detection switch 106 (S401). When the open / close detection switch 107 is in the open state and when the rotation detection switch 106 is not rotating, the forward rotation state is detected, and when the open / close detection switch 107 is closed and the rotation detection switch 106 detects the rotation state, the reverse storage state is detected. In the case, the process proceeds to S404. Then, the 2D3D display switching unit 108 displays an image in which the left-eye image and the right-eye image are arranged in a stripe pattern on the display panel 109A, and the display unit 109 displays the parallax barrier panel 109B in a stripe pattern. A 3D display is set (S407). In the normal rotation state and the reverse storage state, since the observer of the display unit 109 is a photographer, the viewer is always in a proper 3D visual recognition position, and thus is set to 3D display.

  If the open / close detection switch 107 is in the open state and the rotation detection switch 106 is in the facing state in which the rotation state is detected in S401, the process proceeds to S403. Then, the 2D3D display switching unit 108 displays either the left-eye image or the right-eye image on the display panel 109A, the parallax barrier panel 109B is set to a full transmission pattern, and the display on the display unit 109 is set to 2D display. (S406). This is because, in photographing in a face-to-face state, the observer of the display unit 109 varies depending on the situation to be photographed, and there are many scenes that are not in the proper 3D visual recognition position. For this reason, an image in which the image for the left eye and the image for the right eye are overlapped is viewed, making it difficult to visually recognize the display image. Therefore, it is possible to improve the visibility when confirming the display video by performing 2D display.

  In the case of the forward rotation storage state in which the open / close detection switch 107 is closed and the rotation detection switch 106 is not rotated in S401, the process proceeds to S402, and the display unit 109 is turned OFF and is not displayed (S405).

  After performing the above processing, it is determined whether shooting or reproduction is continued (S408), and the processing of S401 is repeated until the power is turned off and the control ends. When the power is turned off, this process is terminated.

  As described above, according to the video camera of the first embodiment, the display unit 109 is switched to the 2D display in the face-to-face state, so that the display image can be surely confirmed in any position in the face-to-face state. Can be done.

<Second Embodiment>
Next, a method for controlling the switching of the video displayed on the display unit 109 in the second embodiment of the present invention will be described. Since the configuration of the image pickup apparatus of the second embodiment is substantially the same as that of the first embodiment, the description of the same components will be omitted by using the same reference numerals, and different configurations will be described here. To do.

  FIG. 5 is a block diagram showing a configuration of an image pickup apparatus in an embodiment of the invention of claim 4. In the first embodiment, a touch panel 501 and a touch panel control unit 502 are added, and an input operation using the touch panel 501 disposed on the display unit 109 is made possible. When the touch panel 501 is pressed, the touch panel control unit 502 calculates input coordinates. The control microcomputer 104 performs processing according to the coordinate position. The touch panel 501 may be any of various types of touch panels such as a resistive film method, a capacitance method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, an image recognition method, and an optical sensor method. good.

  FIG. 6 is a flowchart showing a switching control procedure of a video displayed on the display unit 109 in the embodiment of the invention of claim 4. This process is executed by the control microcomputer 104. Since S601 to S606 and S608 in FIG. 6 are the same processes as S401 to S407 in FIG.

  In FIG. 6, in S <b> 607, the touch panel control unit 502 determines whether or not there is an operation on the touch panel 501. When the touch panel 501 is not operated, 2D display is continued. If the touch panel has been operated, the process proceeds to S608. Then, the display on the display unit 109 is switched to 3D display by the 2D3D display switching unit 108 (S608). This is because, in photographing in a face-to-face state, the observer of the display unit 109 varies depending on the situation to be photographed, and there are many scenes that are not in the proper 3D visual recognition position. For this reason, an image in which the image for the left eye and the image for the right eye are overlapped is viewed, and it is difficult to visually recognize the display image, so that the 2D display is used. However, when operating the touch panel, the observer is in the proper 3D visual recognition position, so the display is switched to 3D display. That is, even in the face-to-face state, when the observer is in the 3D visual recognition position, 3D display is performed, and when the observer is in a position not suitable for 3D visual display, the 2D display is performed. Can be improved.

  After performing the above processing, it is determined whether shooting or reproduction is continued (S609), and the processing of S601 is repeated until the power is turned off and the control ends. When the power is turned off, this process is terminated.

  Further, the 3D display period when the operation of the touch panel is performed may be arbitrarily selected.

  As described above, according to the video camera of the second embodiment, the display 109 is switched to 2D display when in the face-to-face state, and the display is switched to 3D display when the touch panel is operated. It is possible to surely check the display image regardless of where the person is.

<Third Embodiment>
Next, a method for controlling the switching of the video displayed on the display unit 109 in the third embodiment of the present invention will be described.

  Since the configuration of the image pickup apparatus of the third embodiment is almost the same as that of the first embodiment, the description of the same components will be omitted by using the same reference numerals, and different configurations will be described here. To do.

  FIG. 7 is a block diagram showing the configuration of the image pickup apparatus in the embodiments of the fifth and sixth aspects of the invention. In the first embodiment, a face detection unit 701, a distance measurement unit 702, and a face position detection unit 703 are added to detect the face of the subject from the image data, measure the distance between the imaging device and the subject, and the display unit 109. The position of the face of the subject relative to can be detected. Further, an operation mode selection unit 704 is added so that a shooting mode for shooting and a playback mode for playing back video can be selected. The face detection unit 701 uses image data to detect whether a human face exists on the screen.

  As a human face detection method, an eigenface method based on principal component analysis or a method using feature points such as eyes, nose, and mouth can be applied. In these methods, it is determined whether or not the input image is a human face by a pattern matching method between the input image and a plurality of standard patterns. The distance measuring unit 702 calculates the distance to the subject using a distance measuring sensor. The distance to the subject can also be calculated from the zoom position information that is in focus. Alternatively, measurement may be performed using an image sensor with a built-in distance sensor. The face position detection unit 703 detects whether or not there is a face at an appropriate 3D visual recognition position with respect to the display unit 109.

  As a method for detecting the position of the face with respect to the display unit 109, first, the distance between the face detected by the face detection unit 701 and the display unit 109, and zoom position information are used as condition parameters. Then, it is possible to detect the face position coordinates with the face in front of the display unit 109 according to the condition parameter. In this embodiment, it is assumed that a parameter table as shown in FIG. 9 is stored in the program memory. Necessary conditions vary depending on the 3D viewing conditions of the display unit 109 to be used, and need to be changed as appropriate.

  FIG. 8 is a flowchart showing a switching control procedure of a video displayed on the display unit 109 in the embodiments of the fifth and sixth aspects of the invention. This process is executed by the control microcomputer 104. Note that steps S802 to S807 and S811 in FIG. 8 are the same as steps S401 to S407 in FIG.

  In FIG. 8, in S808, the face detection unit 701 detects the face of the subject. If a human face is detected, the process proceeds to S809. In step S809, the distance measurement unit 702 measures the distance to the face detected in step S808. If the distance between the video camera and the face is within the appropriate viewing distance range of 3D display, the process proceeds to S810. In the present embodiment, the 3D viewing appropriate viewing distance range is 30 cm to 1 m. In step S810, the face position detection unit 703 detects where the face detected in step S808 is located with respect to the display unit 109.

  If the face position is within the appropriate viewing angle range for 3D display, the display unit 109 is switched to 3D display by the 2D3D display switching unit 108 (S811). In this embodiment, the proper viewing angle range for 3D viewing is only the front. If the face is not detected in S808, if the distance from the subject is out of the proper viewing distance in 809, and if the face position is out of the proper viewing angle of the display unit 109 in S810, go to S812. move on. It is determined whether shooting or reproduction is continued (S812), and the process of S801 is repeated until the power is turned off and the control is completed. When the power is turned off, this process is terminated. That is, in the face-to-face shooting, the display image is confirmed because the display is switched to 3D display when it is detected that the observer is at an appropriate position for 3D viewing, and is switched to 2D display when it is not at the proper position. It becomes possible to improve the visibility at the time.

  After performing the above processing, it is determined whether shooting or reproduction is continued (S812), and the processing of S801 is repeated until the power is turned off and the control is completed. When the power is turned off, this process is terminated.

  As described above, according to the video camera in the third embodiment, the display unit 109 is switched to the 2D display in the shooting mode and the face-to-face state, and the 3D display is performed when the observer is at the proper 3D viewing position. Since the switching is performed, the display image can be reliably confirmed regardless of where the observer is in the face-to-face state.

  Further, in this embodiment, the appropriate viewing distance range for 3D viewing is 30 cm to 1 m, but it varies depending on the device used as the display unit, and needs to be changed as appropriate. Further, in this embodiment, a table is prepared only when the face position is the front of the display unit 109 as the appropriate 3D viewing angle. However, when the 3D viewing angle is wide, it is necessary to prepare a plurality of tables other than the front. There is. Further, in this embodiment, switching between 2D display and 3D display is performed based on the operation mode and the attitude of the display unit 109 based on claim 5, but in the control of the first and second embodiments, the determination according to the operation mode is performed. May be added. In this embodiment, 3D display is used in the playback mode. However, 2D display and 3D display may be switched by menu operation or the like.

  In the first to third embodiments, when 2D display is performed, one of the left-eye image and the right-eye image is displayed on the display panel 109A. A composite image from the right-eye image may be used. Moreover, in the said Examples 1-3, the judgment of the display switching of the display part 109 is performed individually in each Example, However, You may combine and use the judgment in the said Examples 1-3. In the first to third embodiments, the parallax barrier method is used as a method for visually recognizing a stereoscopic image. However, the present invention is not limited to this method, and can be applied to various other stereoscopic image display methods.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included.
