Description

  The present invention relates to a three-dimensional display that displays an image three-dimensionally. The present invention also relates to a display method for displaying an image on such a three-dimensional display. Furthermore, the present invention relates to a program for operating a computer as such a three-dimensional display, and a recording medium on which such a program is recorded.

  3D displays have begun to penetrate the market and stereoscopic viewing of 3D images is becoming familiar. Examples of the 3D display include a 3D digital photo frame capable of displaying a 3D still image in addition to a 3D television receiver capable of displaying a 3D moving image.

  Such a three-dimensional display is often used in combination with a 3D digital camera capable of capturing a three-dimensional still image. In a 3D digital camera, a two-dimensional image file and a three-dimensional image file are generated simultaneously by one imaging. As a format of the three-dimensional image file, a multi-picture format (extension is .mpo) that can store a left-eye image and a right-eye image is generally used (see Non-Patent Document 1). .

  In addition, 3D digital camera modules for mobile devices have been developed that can shoot 3D images of high-definition high-definition signals. It is also possible to enjoy high-definition 3D images captured by a 3D digital camera equipped with such a 3D digital camera module, a 3D mobile phone terminal, or the like in a 3D high-definition television receiver.

  Non-Patent Document 2 describes a digital photo frame that includes an infrared communication port and receives and displays a still image transmitted from a 3D digital camera. This digital photo frame has a function to display a three-dimensional image in two dimensions and a function to display a (pseudo) three-dimensional image of a two-dimensional image, and receives a two-dimensional image when performing three-dimensional display. Then, a configuration is adopted in which the received image is (pseudo) three-dimensionally displayed, and when the three-dimensional image is received during the two-dimensional display, the received image is two-dimensionally displayed. The (pseudo) three-dimensional display in the digital photo frame described in Non-Patent Document 2 is realized by presenting a single two-dimensional image to both eyes of the user.

Camera Video Equipment Industry Association Standard CIPA DC-007-2009 Multi-Picture Format Established February 4, 2009 “FinePix REAL 3D V1” [online], Fuji Film, (searched on May 21, 2010), Internet <http://fujifile.jp/personal/3d/viewer/finepixreal3dv1/index.html>

  When it is desired to display a still image captured by a 3D digital camera in a three-dimensional display on a digital photo frame, the user instructs the 3D digital camera to transmit the three-dimensional image. In addition, when a two-dimensional display of a still image captured by a 3D digital camera is desired on a digital photo frame, the user instructs the 3D digital camera to transmit the two-dimensional image.

  However, in the digital photo frame described in Non-Patent Document 2, as described above, a (pseudo) 3D display is performed even though a 2D image is transmitted from the 3D digital camera. Two-dimensional display is performed even though the image is transmitted. That is, the operation of the digital photo frame described in Non-Patent Document 2 is an operation different from the operation requested by the user, and there is a problem that the user feels uncomfortable. Further, there is a problem that it is difficult for the user to confirm whether or not an image according to the instruction is transmitted from the 3D digital camera. That is, the digital photo frame described in Non-Patent Document 2 is not easy for the user to use.

  The present invention has been made to solve the above-described problems, and a main object thereof is to realize a three-dimensional display device that is easier to use for a user.

  In order to solve the above problems, a three-dimensional display device according to the present invention determines an image receiving unit that receives an image and whether the image received by the image receiving unit is a two-dimensional image or a three-dimensional image. And a display control means for displaying the image received by the image receiving means on the display unit, and when the determining means determines that the image is a three-dimensional image, Display control means for displaying and displaying the image in a two-dimensional manner when the determination means determines that the image is a two-dimensional image.

  In order to solve the above problem, a display method according to the present invention is a display method for displaying an image on a three-dimensional display device, which is received at an image receiving step for receiving an image and at the image receiving step. A determination step for determining whether the image is a two-dimensional image or a three-dimensional image, and a display control step for causing the display unit to display the image received in the image reception step. A display control step of displaying the image three-dimensionally if it is determined to be a three-dimensional image, and displaying the image two-dimensionally if the image is determined to be a two-dimensional image by the determination step; It is characterized by containing.

  According to the above configuration, the three-dimensional display device displays two-dimensionally if the image received by the image receiving means is a two-dimensional image regardless of whether the two-dimensional display or the three-dimensional display is performed, If the image received by the image receiving means is a three-dimensional image, it is displayed three-dimensionally. In other words, this 3D display device does not determine the display format (whether 2D display or 3D display is performed) when displaying the received image according to the current display format, but the received image. The data format (whether it is a two-dimensional image or a three-dimensional image) is determined.

  As a result, 3D display is performed despite the transmission of the 2D image to the 3D display device, or 2D display is performed despite the transmission of the 3D image to the 3D display device. It is possible to realize a three-display device that is easy to use for the user without being broken.

  Note that the three-dimensional image refers to an image (image data) including a right eye image to be presented to the user's right eye and a left eye image to be presented to the user's left eye. Further, three-dimensional display of a three-dimensional image selectively presents a right-eye image included in the three-dimensional image to the user's right eye, and selectively displays a left-eye image included in the three-dimensional image to the user's left eye.

Can immediately notice the mistake. At this time, by instructing the 3D display device to switch to the 2D display, the 2D image can be displayed on the 3D display device without transmitting the 2D image again.

  Note that the pseudo 3D image refers to a 3D image including a right eye image and a left eye image generated from a single 2D image. Even when a pseudo three-dimensional image is displayed in three dimensions by giving a difference (parallax) according to depth information obtained by image analysis of the original two-dimensional image between the right eye image and the left eye image As in the case of three-dimensional display of a three-dimensional image, stereoscopic vision can be realized.

It is preferable to display two-dimensionally the image that has been decoded first.

  According to the above configuration, nothing is displayed on the display unit as compared with the case where the three-dimensional display of the right-eye image and the left-eye image is not started until the decoding of the right-eye image and the decoding of the left-eye image are completed. It is possible to shorten the period of not being displayed.

A second storage unit, and the display control means starts the three-dimensional display of the second three-dimensional image stored in the second storage unit until the first storage unit It is preferable that the first three-dimensional image stored in is continuously displayed in three dimensions.

  According to the above configuration, the 3D display device starts the 3D display of the second 3D image stored in the second storage unit (for example, the right-eye image included in the second 3D image). And the left-eye image are completely decoded), the first three-dimensional image stored in the first storage unit is continuously displayed. Therefore, the user can see the first three-dimensional image and the second three-dimensional image continuously.

  In the three-dimensional display device according to the present invention, when the image receiving unit cannot normally receive either the right-eye image or the left-eye image included in the three-dimensional image, the right-eye image and the right-eye image It is preferable to display two-dimensionally the image that has been normally received among the left-eye images.

  According to the above configuration, the user can easily confirm which image is the image that the three-dimensional display device cannot normally receive.

FIG. 2 is a flowchart showing the flow of received image display processing executed on the television 1. Each step included in the flowchart shown in FIG. 2 will be described in order as follows.

  Step S11: When an image received using IrSS (hereinafter also referred to as “received image”) is supplied from the IrSS infrared light receiving unit 120, the CPU 118 stores the received image in the RAM 117. The OSD generation unit 106 creates an OSD screen indicating that an image is received and supplies the OSD screen to the LCD controller 109. The LCD controller 109 displays the received OSD screen on the LCD 110.

  Step S12: The CPU 118 determines whether the received image received from the IrSS infrared light receiving unit 120 is a two-dimensional image or a three-dimensional image. If it is a two-dimensional image, step S13 is executed. If it is a three-dimensional image, step S21 is executed.

  Step S13: The OSD generation unit 106 decodes the received two-dimensional image, and generates a two-dimensional video having the decoded two-dimensional image as a frame image.

  Step S14: If the LCD controller 109 is currently displaying three-dimensionally, the LCD controller 109 performs a two-dimensional process such as changing the panel driving speed to display a two-dimensional image in two dimensions. While the two-dimensionalization process is being performed, the display is muted and a black screen is displayed on the LCD 110.

  Step S15: The LCD controller 109 causes the LCD 110 to two-dimensionally display the two-dimensional video generated in step S13.

  Step S16: When another image is supplied from the IrSS infrared light receiving unit 120, the CPU 118 returns to Step S11.

  Step S17: The CPU 118 indicates a remote control signal indicating that an operation for instructing the remote control to switch from the two-dimensional display to the three-dimensional display (for example, an operation of pressing a “3D button” provided on the remote control) is performed. Is determined by the remote control infrared light receiving unit 119. If the remote control infrared light receiving unit 119 has received this remote control signal, step S17 is executed. If not received, the process returns to step S16.

  Step S18: The LCD controller 109 performs a three-dimensional process such as changing the panel driving speed in order to switch from the two-dimensional display to the three-dimensional display. While performing the three-dimensional processing, the display is muted and a black screen is displayed on the LCD 110.

  Step S19: The 2D-3D conversion unit 132 generates a pseudo 3D video from the 2D video generated in Step S13. Further, the 3D processing unit 131 converts a pseudo three-dimensional video (side-by-side method or top-and-bottom method) including a frame image including both the right-eye image and the left-eye image into a right-eye frame image including only the right-eye image. The image is converted into a pseudo 3D image including a left-eye frame image including only the left-eye image.

  Step S20: The LCD controller 109 displays the three-dimensional video generated in step S19 on the LCD 110 in three dimensions. Thereafter, step S24 is executed.

  Step S21: When the received image is a three-dimensional image in step S12, the OSD generation unit 106 uses a frame image including both the left-eye image and the right-eye image obtained by decoding the received three-dimensional image. A 3D image (side-by-side method or top-and-bottom method) is generated. The 3D processing unit 131 converts the 3D video generated by the OSD generation unit 106 into a 3D video composed of a right-eye frame image including only the right-eye image and a left-eye frame image including only the left-eye image. Convert.

  Step S22: When the two-dimensional display is currently being performed, the LCD controller 109 performs a three-dimensional process such as changing the panel drive speed in order to switch from the two-dimensional display to the three-dimensional display. While performing the three-dimensional processing, the display is muted and a black screen is displayed on the LCD 110.

  Step S23: The LCD controller 109 displays the three-dimensional image generated in step S21 on the LCD 110 in three dimensions.

  Step S24: If another image is supplied from the IrSS infrared light receiving unit 120, the CPU 118 returns to step S11.

  Step S25: The CPU 118 indicates that an operation for instructing the remote control to switch from the three-dimensional display to the two-dimensional display (for example, an operation of pressing the “3D button” provided on the remote control again) is performed. It is determined whether or not the remote control infrared light receiving unit 119 has received the signal. If the remote control infrared light receiving unit 119 has received this remote control signal, step S26 is executed. If not received, the process returns to step S24.

  Step S26: The LCD controller 109 performs a two-dimensional process such as changing the panel driving speed in order to switch from the three-dimensional display to the two-dimensional display. While the two-dimensionalization process is being performed, the display is muted and a black screen is displayed on the LCD 110.

  Step S27: The 2D-3D conversion unit 132 extracts either the left-eye image or the right-eye image of the 3D video displayed in Step S23, and the 2D image is framed from the 2D image whose size has been adjusted. A 2D video image is generated.

  Step S28: The LCD controller 109 displays the two-dimensional image generated in step S27 on the LCD 110 in two dimensions. Thereafter, Step S16 is executed.

  In step S19, when data for 3D display of a 2D video (3D image) is recorded in the RAM 117, the OSD generation unit 106 decodes the 3D image instead of step S19. A three-dimensional image (side-by-side method or top-and-bottom method) including a frame image including both the left-eye image and the right-eye image obtained by decoding may be generated.

  In step S27, when data for two-dimensional display of a three-dimensional image (two-dimensional image) is recorded in the RAM 117, the OSD generation unit 106 decodes the two-dimensional image instead of step S27, A two-dimensional image using the decoded two-dimensional image as a frame image may be generated.

  In the flowchart shown in FIG. 2, when an end instruction is received from the user, the received image display process is ended.

  As a result, regardless of whether the television 1 is performing two-dimensional display or three-dimensional display, if the image received by the IrSS infrared light receiving unit 120 is a two-dimensional image, the image is displayed in two dimensions. A three-dimensional image can be displayed in three dimensions.

  That is, the television 1 does not determine the display format (whether to perform two-dimensional display or three-dimensional display) when displaying the received image, depending on the current display format, but the data format of the received image. It is determined according to whether it is a two-dimensional image or a three-dimensional image.

  As a result, the television 1 performs a three-dimensional display in spite of transmitting a two-dimensional image to the television 1, or performs a two-dimensional display in spite of transmitting a three-dimensional image to the television 1. There is no breakage.

  In addition, the user can receive the two-dimensional image on the television 1 and display the two-dimensional image, and then display the pseudo three-dimensional image generated from the two-dimensional image on the television 1 in three dimensions. Further, the user can receive a three-dimensional image on the television 1 and display it three-dimensionally, and then display the two-dimensional image extracted from the three-dimensional image on the television 1 two-dimensionally. That is, the user can freely switch between performing two-dimensional display or three-dimensional display on the television 1.

  FIG. 3 is an example of a screen displayed on the television 1 when the received image display process is executed. The left column of FIG. 3 shows the processing contents in the received image display processing over time. The right column shows an example of a screen displayed on the television 1 while the processing shown in the left column is being executed.

  When the television 1 starts to receive an image, a message “IrSS is being received” indicating that the image is being received is displayed in an OSD manner as shown in the screen a. Note that the message indicating that the image is being received is not limited to this, and may be a message indicating that the image is being received.

  When the television 1 receives the image, the television 1 decodes the image for the left eye. While decoding the left-eye image, the television 1 mutes the screen (screen b).

  When the decoding of the left-eye image is completed, the television 1 starts decoding the right-eye image. At this time, the screen c displaying the left-eye image that has already been decoded is displayed.

  When the decoding of the right-eye image is completed, the television 1 generates a three-dimensional video (side-by-side method or top-and-bottom method) including a frame image including both the left-eye image and the right-eye image. Also, settings are made to enable three-dimensional display, such as changing the panel drive speed and setting 3D glasses driving. During this time, the television 1 mutes the screen (screen d).

  When the setting of the 3D display is completed, the 3D image is displayed in 3D on the television 1 (screen e).

  As described above, since no image is displayed on the television 1 only while the decoding of the left-eye image of the three-dimensional image is completed, nothing is displayed until the decoding of both the left-eye image and the right-eye image is completed. As compared with, since the period during which nothing is displayed on the display unit is shortened, the waiting time of the user can be shortened.

  In addition, when the video being viewed is displayed in 3D and the received 3D image is displayed in 3D, the screen d is displayed because there is no need to change the panel driving speed or the 3D glasses driving setting again. You don't have to. Thereby, it is possible to switch from the state of the screen c displaying the OSD display of the message or the image for the left eye to the screen e.

  FIG. 4 shows that the television 1 receives a new three-dimensional image (second three-dimensional image) while the three-dimensional image (first three-dimensional image) is three-dimensionally displayed on the television 1 (screen e). It is an example of a screen displayed on the television 1 when the received image display process is executed. The first column in FIG. 4 shows the processing contents in the received image display process over time, and the second column shows a screen displayed on the television 1 while the process shown in the first column is being executed. ing. The third and fourth columns show the left-eye and right-eye images of the three-dimensional image stored in the display buffer, and the fifth and sixth columns are 3 stored in the decoding buffer. The image for left eyes and the image for right eyes of a three-dimensional image are shown.

  When the television 1 receives the image, it displays an OSD message “IrSS is being received” indicating that the image is being received. Note that the message indicating that the image is being received is not limited to this, and may be a message indicating that the image is being received.

  When the television 1 receives the image, the television 1 decodes the image for the left eye. While the left-eye image is being decoded, the left-eye image in the decoding buffer is switched to the decoded image. At this time, since the image in the display buffer does not change, the television 1 displays the screen e without muting the screen even during decoding.

  While the decoding of the left-eye image is completed and the right-eye image is being decoded, the right-eye image in the decoding buffer is switched to the decoded image. Since the image in the display buffer does not change, the television 1 displays the screen e without muting the screen even during decoding.

  When the decoding of the right-eye image is completed, the left-eye image and the right-eye image stored in the display buffer are replaced with the decoded left-eye image and right-eye image stored in the decoding buffer. Thereafter, the screen f on which the new received image is displayed is three-dimensionally displayed on the television 1.

  Accordingly, the television 1 continues to display the 3D image stored in the display buffer until the 3D display of the 3D image stored in the decoding buffer is started. Therefore, the user can continuously view the previously displayed three-dimensional image and the newly received three-dimensional image.

  FIG. 5 is an example of a screen displayed on the television 1 when a received image display process is executed when an error occurs in the middle of receiving an image using the IrSS.

  When the television 1 receives the image, the message “IrSS is being received” indicating that the image is being received is displayed in an OSD manner as shown in the screen g. Note that the message indicating that the image is being received is not limited to this, and may be a message indicating that the image is being received.

  When the television 1 receives the left-eye image, the television 1 decodes the left-eye image. While decoding the left-eye image, the television 1 mutes the screen (screen h).

  When the decoding of the left-eye image is completed, the television 1 starts decoding the right-eye image. If an error occurs during the reception of the right-eye image and the right-eye image cannot be received normally, the television 1 displays an OSD-displayed screen i in which the already-decoded left-eye image and an error have occurred. Is displayed two-dimensionally. The message displayed on the OSD is not limited to this, and may be a message indicating the error that has occurred.

  After the error has occurred, the image in which the reception error has occurred is received again to complete the decoding of the right-eye image, and the television 1 displays the received three-dimensional image in three dimensions (screen j).

  Thereby, the user can easily confirm which image is the image that could not be normally received among the received images.

  The image received again after the error may be an image retransmitted by the user or automatically transmitted by a retransmission request transmitted from the television 1 using bidirectional communication such as IrSimple. It may be an image.

  In the present embodiment, the left-eye image and the right-eye image of the three-dimensional image may be reversed left and right. For example, in the present embodiment, the description has been given in which the decoding of the three-dimensional image is performed from the left-eye image, but may be performed from the right-eye image.

  In addition, the 3D display device is not limited to a television, but a display monitor equipped with a 3D display, a PC monitor, a mobile phone terminal, a mobile terminal device, a car navigation display, etc. The photographed high-definition 3D image can be transmitted and applied suitably.
