Description

  The present invention relates to an imaging apparatus capable of switching a subject to a two-dimensional (2D) image while photographing a subject with a three-dimensional (3D) image.

  Conventionally, various methods for displaying a three-dimensional image have been proposed. Among them, what is generally used is a so-called “binocular type” that uses binocular parallax. In other words, a left-eye image and a right-eye image having binocular parallax are prepared, and stereoscopic vision is performed by projecting them to the left and right eyes independently.

  FIG. 13 is a conceptual diagram for explaining a “parallax barrier system” which is a typical twin-lens system. FIG. 13A is a diagram illustrating the principle of generating parallax. On the other hand, FIG.13 (b) is a figure which shows the screen displayed by a parallax barrier system.

  In FIG. 13A, an image in which the left-eye image and the right-eye image are alternately arranged every other pixel in the horizontal direction as shown in FIG. 13B is displayed on the image display panel 101. Then, by placing the parallax barrier 102 having slits at an interval narrower than the interval of pixels of the same viewpoint on the front surface of the image display panel 101, the left eye image is only the left eye 103, and the right eye image is the right eye 104. Therefore, stereoscopic observation can be performed.

  By the way, as in the parallax barrier method, there is a “lenticular method” as a method for three-dimensionally displaying an image as shown in FIG. 13B.

  FIG. 14 is a conceptual diagram showing an example of such a lenticular recording data format. From the left eye image 201 shown in FIG. 14 (a) and the right eye image 202 shown in FIG. 14 (b), each of them is thinned in half in the horizontal direction, and one mixed image shown in FIG. 14 (c) An image 203 is created and recorded. At the time of reproduction, the composite image 203 is rearranged to create a composite image as shown in FIG.

  Although the above description is a method for forming a 3D image by combining images from two viewpoints, it is naturally conceivable to form an image from multiple viewpoints. In this case, images viewed from each viewpoint are arranged based on a certain rule.

  As described above, in order to photograph a 3D image in which a photographed subject can be viewed stereoscopically by separately viewing a plurality of images having parallax with respect to the subject with the left and right eyes, A stereo adapter that forms a plurality of subject images with different viewpoints is attached to a monocular camera, and a plurality of images with parallax are captured on one screen.

In a 3D image photographing device equipped with a stereo adapter, when a release button is operated, a subject distance is first obtained from focal length and focus lens position information, and the subject distance is compared with a reference predetermined distance. When the subject distance is shorter than a predetermined distance, the parallax is too large to make stereoscopic viewing impossible, so that shooting is prohibited or shooting is performed but a warning is displayed (Patent Document 1). reference).
JP 2001-222083 A

  The conventional photographing apparatus has a problem that it is not possible to photograph a scene to be photographed when photographing is prohibited by the process of making it impossible to press the shutter as described above.

Moreover, when displaying a warning as mentioned above, it has the following problems.
1. When a warning is displayed but shooting is allowed, a 3D image is shot even if the shooting conditions are bad, so a 3D image that cannot be stereoscopically viewed is output.
2. The warning display is determined only once at the start of shooting, does not take into account changes during shooting, and does not consider the case of shooting moving images. Therefore, when the subject distance changes, for example, when the subject is approaching during moving image shooting, a 3D image that cannot be viewed stereoscopically is output.
3. Although it is conceivable that the 3D image is forcibly displayed as a 2D image when the user reproduces the captured image, the user needs to switch the screen manually while viewing the screen, and the operation is complicated and usability is poor.

  In view of such circumstances, the present invention provides a photographing apparatus that generates image data that can be displayed in another display form when a photographed three-dimensional image is reproduced and is not suitable for three-dimensional display. It is for the purpose.

  The present invention relates to an imaging unit that inputs images of a plurality of viewpoints, a determination unit that determines whether or not the images of the plurality of viewpoints are stereoscopically viewable, and image data that generates image data according to the determination result of the determination unit And a creation unit, wherein the image data creation unit corrects the images of the plurality of viewpoints and creates image data when the determination result of the determination unit is inappropriate.

  Further, the image data creation unit includes a control information creation unit that creates a parameter indicating the format of the output image as control information.

  Further, the image data creation unit corrects the stereoscopic effect when the images of the plurality of viewpoints are three-dimensionally displayed when the determination result is inappropriate.

  According to the present invention, in the imaging apparatus, the imaging unit measures a subject distance, and the determination unit determines that the subject distance measured by the imaging unit is closer than a first predetermined distance and / or a second predetermined distance. When the distance is longer than the distance, it is determined to be unsuitable for stereoscopic viewing.

  Further, the image data creation unit includes a control information creation unit that creates a parameter indicating the format of the output image and a subject distance as control information.

  The present invention includes a camera shake correction unit that measures camera shake from the images of the plurality of viewpoints input by the imaging unit, calculates a correction amount thereof, and performs camera shake correction in the imaging device, and the determination unit includes the camera shake When the correction amount exceeds a predetermined amount, it is determined that the correction amount is inappropriate for stereoscopic vision.

  The present invention includes a stereoscopic intensity calculating unit that calculates a stereoscopic intensity indicating a stereoscopic effect when the image data of the plurality of viewpoints is displayed as a three-dimensional image in the imaging apparatus, and the determination unit includes the stereoscopic unit. When the intensity exceeds a predetermined amount, it is determined that the intensity is inappropriate for stereoscopic viewing.

  In addition, the image data creation unit includes a control information creation unit that creates a parameter indicating the format of the output image and a solid intensity as control information.

  Further, the image data creation unit includes a control information creation unit that creates, as control information, a parameter indicating a format of output image data and a flag for restricting stereoscopic display.

  According to the photographing apparatus of the present invention, it is determined whether a photographed three-dimensional image is not suitable for three-dimensional display or an image unsuitable for long-time display. Since the image data is changed to the image data to be used, the image can be taken regardless of the situation, and the reproduced display image can always be automatically displayed in the optimum form.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

<First Embodiment>
FIG. 1 is a block diagram showing a first embodiment of a photographing apparatus according to the present invention.
This photographing apparatus has a configuration including an imaging unit 11, a determination unit 12, a 3D data creation unit 13, a 2D data creation unit 14, and switches 15 and 16. In particular, the portion including the 3D data creation unit 13, the 2D data creation unit 14, and the switches 15 and 16 constitutes an image data creation unit 17 that forms an image.

  The imaging unit 11 is configured to shoot a subject by attaching a stereo adapter to a lens, for example, and outputs stereo pair image data (3D images) of a predetermined number of frames per second (see FIG. 5A). . In addition, when the zoom magnification is designated by an operation unit (not shown), the imaging unit 11 moves the lens to the lens position of the designated magnification, performs autofocus, calculates the subject distance from the lens position, and provides subject distance information. Output.

  The determination unit 12 determines the appropriateness of the stereoscopic view from the subject distance. This determination will be described with reference to FIGS. FIG. 2 is a schematic diagram showing a state in which the left and right images of the subject 108 are formed on the image forming surface 107 through the lens 106 by the stereo adapter 100. The right eye image of the subject 108 is reflected by the mirror 102 and the mirror 103 and formed on the right opposite surface of the image forming surface 107. Further, the left eye image of the subject 108 is reflected by the mirror 104 and the mirror 105 and formed on the left half surface of the image forming surface 107. As can be seen from the figure, it is necessary for the subject 108 to be in a position where it can be seen on both the mirror 103 and the mirror 104 for stereoscopic viewing.

  FIG. 3 is a schematic diagram showing a captured image of the subject 108 on the imaging surface 107. When the subject distance is short, the subject 108 is imaged so as to approach the center portion of the imaging plane 107 as shown in FIG. When the subject distance is long, an image is formed at a position away from the center of the imaging plane 107 as shown in FIG.

  Next, the case where the 3D image photographed as described above is displayed by the above-described parallax barrier method will be described with reference to FIG. FIG. 4 shows a composition in which the state of observing the image displayed on the display is viewed from directly above. When the subject distance is short, the left eye image of the subject is displayed on the right side of the display and the right eye image is displayed on the left side of the display from the positional relationship between the left and right images of the subject shown in FIG. The three-dimensional image is observed at a position raised to the near side of the display surface (see FIG. 4A). Similarly, when the subject distance is far, the left eye image of the subject is displayed on the left side of the display, the right eye image is displayed on the right side of the display, and the stereoscopic image is observed at a position behind the display surface. (See FIG. 4B).

In either case where the subject distance is too close or the subject distance is too far, the parallax between the left eye image and the right eye image of the subject becomes too large and is recognized as a separate image, so Can not. Therefore, in order to determine whether or not stereoscopic viewing is appropriate, a first predetermined distance that is a reference for determining when the subject distance is too close and a second predetermined distance that is a reference for determining when the subject distance is too far Is provided. Then, the determination unit 12 determines that the subject distance is unsuitable for stereoscopic vision when the subject distance is shorter than the first predetermined distance and when the subject distance is longer than the second predetermined distance.
In this embodiment, two predetermined distances are provided, but only one of them may be provided.

  The 3D data creation unit 13 creates 3D data by adding 3D control information to an image captured in stereo according to the input parameters. Here, the parameter is the following information indicating the format of the captured image. That is, information such as the number of viewpoints (horizontal direction and vertical direction), image combination, image arrangement, and image reduction. For example, in the case of the 3D image of FIG. 5A, the number of viewpoints in the horizontal direction = 2, the number of viewpoints in the vertical direction = 1, image combination = present, image layout = normal, image reduction (horizontal direction) = Become. These pieces of information are set before shooting depending on the stereo adapter used. The 3D control information is information including all these parameters, for example.

  The 2D data creation unit 14 creates a 2D data by converting a stereo image into a 2D image. The switch 15 switches whether to output the image data from the imaging unit 11 to the 3D data creation unit 13 or to the 2D data creation unit 14 based on the determination result of the determination unit 12. The switch 16 switches whether to output data from the 3D data creation unit 13 or to output data from the 2D data creation unit 14 based on the determination result of the determination unit 12.

The conversion process from the 3D image to the 2D image by the 2D data creation means 14 includes the following. Which one to select may be selectable by the user.
(1) A 2D image is created by enlarging one of the left and right eye images, for example, twice horizontally (see FIG. 5B). This is a case in which a 3D / 2D mode switchable monitor is used, a 3D image is displayed in 3D mode when stereoscopic viewing is possible, and a 2D image is displayed in 2D mode when unsuitable for stereoscopic viewing.
(2) A stereo pair is created using one of the left and right eye images (see FIG. 5C). In FIG. 5C, the image for the right eye is replaced with the image for the left eye, but the reverse is also possible. This is a case where a 2D image is displayed on only a 3D dedicated monitor. As a result, the left and right eye images are the same, and the left and right parallax are eliminated, and the image is displayed as a 2D image.

  In this photographing apparatus, when photographing is started and the focus is changed by moving image photographing or the like, the imaging unit 11 measures the distance to the subject simultaneously with photographing of the subject. The determination unit 12 compares the subject distance with the reference first and second predetermined distances to determine the appropriateness of the stereoscopic image of the captured image. If the stereoscopic image is possible, the captured image data is input to the switch 15. The 3D data creation unit 13 outputs the data. If the stereoscopic view of the captured image is inappropriate, the switch 15 causes the 2D data creation unit 14 to output the captured image data. Then, the switch 16 outputs the processing data from the 3D data creation unit 13 or the 2D data creation unit 14 based on the determination result of the determination unit 12. That is, if stereoscopic viewing is possible, the switch 16 outputs the processing data from the 3D data creation unit 13. When the stereoscopic view of the photographed image is inappropriate, the switch 16 outputs the processing data from the 2D data creation unit 14.

  In this way, when the determination result of the determination unit is stereoscopically viewable by the image data generation unit 17 including the 3D data generation unit 13, the 2D data generation unit 14, and the switches 15 and 16, three-dimensional image data that can be displayed in three dimensions is displayed. When it is created and unsuitable for stereoscopic vision, image data that can be displayed two-dimensionally is created. Therefore, even if the user shoots a captured image without determining whether or not the 3D image is suitable, the photographing apparatus is in an optimal form. Can output data that can be automatically displayed.

Second Embodiment
FIG. 8 is a block diagram showing a second embodiment of the photographing apparatus according to the present invention. In FIG. 8, the same parts as those in FIG.
In this imaging apparatus, a camera shake correction unit 21 is disposed between the imaging unit 11, the determination unit 22, and the switch 15. The camera shake correction unit 21 measures camera shake from the three-dimensional image data captured by the imaging unit 11, calculates a correction amount thereof, performs camera shake correction, outputs image data that has undergone camera shake correction to the switch 15, and outputs a determination unit. A camera shake correction amount is output to 22. The determination unit 22 uses the camera shake correction amount as a condition for determining whether or not stereoscopic viewing is possible. That is, when the amount of camera shake correction exceeds a predetermined value, that is, when camera shake is severe, the switch 15 outputs the image data subjected to camera shake correction to the 2D data creation unit 14 to create and output a 2D image. At this time, switching may be prohibited for a certain period of time so that frequent switching does not occur.

Since this photographing apparatus automatically outputs 2D image data in a camera shake state that causes discomfort and fatigue to the user if 3D display is performed, optimal image data can always be output.
Note that the determination of whether or not it is suitable for stereoscopic viewing may be performed not only based on the amount of camera shake correction but also based on the determination based on the subject distance as described in the first embodiment.

<Third Embodiment>
FIG. 9 is a block diagram showing a third embodiment of the photographing apparatus according to the present invention. 9, the same parts as those in FIG. 1 are denoted by the same reference numerals. In this image capturing device, the image data creation unit 25 creates normal 3D image data or 3D image data with reduced stereoscopic effect by reducing the parallax, depending on whether the determination unit 12 determines whether or not stereoscopic viewing is possible. . The photographing apparatus includes an imaging unit 11, a determination unit 12, and an image data creation unit 25. Furthermore, the image data creation unit 25 includes a 3D image data creation unit 13 that creates 3D data including a normal 3D image, and a corrected 3D image data creation unit 24 that creates 3D data including a 3D image with a reduced stereoscopic effect. Consists of including.

  The determination unit 12 compares the subject distance with a predetermined reference distance, and determines the appropriateness of the stereoscopic view of the captured image in the same manner as the determination method described in the first embodiment. The image data creation unit 25 creates and outputs 3D image data based on the determination result. At this time, if the stereoscopic result of the captured image is inappropriate in the determination result, a process for reducing the stereoscopic effect is required. Therefore, the determination unit 12 switches the switch 15 to the correction 3D data creation unit 24 side. Image data output from the imaging unit 11 is input to the corrected 3D data creation unit 24. The corrected 3D data creation unit 24 processes the image data so that the stereoscopic effect of the 3D image is weakened.

Hereinafter, an example of the corrected 3D data creation unit 24 will be described.
FIG. 10 is a block diagram showing an example of the corrected 3D data creation unit 24. As shown in FIG. The corrected 3D data creation unit 24 includes a 3D control information creation unit 31, an image conversion unit 32, an encoding unit 33, and a multiplexing unit 34.

The image conversion unit 32 performs the following 3D image correction processing on the 3D captured image data output from the imaging unit 11.
(1) A movement process is performed so that the parallax of the other image is reduced in accordance with one of the left and right eye images (see FIG. 6). FIG. 6A shows an image that can be stereoscopically viewed in a state of being raised above the display surface. In this case, it is possible to reduce the amount of parallax and weaken the stereoscopic effect by moving the right-eye image to the right.
(2) The image is cut out from the left and right eye images so that there is no parallax, and a new left and right eye image is processed (see FIG. 7). This is particularly effective for electronic zoom zoom images.

Then, the image data subjected to the correction process is encoded by the encoding unit 33 by a predetermined method. On the other hand, the 3D control information creation unit 31 creates 3D control information by collecting parameters. The multiplexing unit 34 multiplexes the encoded image data and 3D control information data and outputs the multiplexed data.
Note that the appropriateness of stereoscopic vision may be determined by not only the subject distance but also the determination based on the camera shake correction amount as described in the second embodiment.

<Fourth embodiment>
FIG. 11 is a block diagram showing a fourth embodiment of the photographing apparatus according to the present invention. In FIG. 11, the same parts as those in FIG. The photographing apparatus further includes a three-dimensional intensity calculation unit 26 that calculates the three-dimensional intensity of the image data captured by the imaging unit 11, and the three-dimensional intensity calculated by the three-dimensional intensity calculation unit 26 is input to the image data creation unit 29. .
At this time, the display time of the 3D image is defined according to the stereoscopic strength, and when the specified 3D display time has passed, information for prompting the 2D display is also added on the display device.

  Here, the three-dimensional strength is an index indicating the magnitude of the three-dimensional effect. The stereoscopic image has parallax, and the observer senses the stereoscopic effect by the parallax. Although the parallax of each pixel of the stereoscopic image is different, the stereoscopic effect of the stereoscopic image with many pixels having large parallax is strong, and the stereoscopic effect of the stereoscopic image with small parallax is weak. In general, when observing a stereoscopic image having a high stereoscopic strength, eye fatigue is accelerated compared to a stereoscopic image having a low stereoscopic strength. Therefore, it is necessary to provide a difference in the allowable time for stereoscopic display depending on the stereoscopic strength. Therefore, when the stereoscopic strength exceeds a certain value, the stereoscopic effect is weakened or a limitation is placed on the time for stereoscopic display.

  The solid strength calculation unit 26 calculates the solid strength based on the image data from the imaging unit 11. The solid intensity is objectively determined by the average value of parallax in each pixel. A weighted average value, median value, maximum value, or the like may be used instead of the average value.

The determination unit 12 determines the appropriateness of stereoscopic vision of the captured image based on the three-dimensional intensity output from the three-dimensional intensity calculation unit 16. The image data creation unit 29 creates a 3D image based on the determination result, the solid intensity, and the parameter. The stereoscopic strength is added to the 3D control information, and the 3D image and the 3D control information are multiplexed to output 3D data.
At this time, if the stereoscopic result of the photographed image is inappropriate in the determination result, 3D data including a 3D image with a reduced stereoscopic effect is created by the corrected 3D data creation unit 28 as in the third embodiment described above. By correcting the stereoscopic effect to be weak, the stereoscopic intensity of the 3D image changes from the value input from the stereoscopic intensity calculating unit 26. Therefore, the corrected 3D data creation unit 28 makes some changes when adding the solid intensity to the 3D control information. For example, it may be replaced with a fixed value such as a maximum value or an intermediate value that can be taken by the three-dimensional strength, or the input three-dimensional strength may be corrected according to the movement amount in the movement processing when correcting the 3D image. Good. Alternatively, the corrected 3D image may be input to the 3D intensity calculation unit 26 to calculate the 3D intensity again.
In addition, when a state unsuitable for stereoscopic vision continues for a predetermined time for a predetermined time, information on forced 2D display, which is a flag for forcibly performing 2D display on the display device, may be added to the 3D control information.

  In this way, since this imaging apparatus determines appropriateness of stereoscopic vision according to the stereoscopic strength and outputs 3D control information, it can always be automatically displayed in an optimal form. Note that the appropriateness of stereoscopic vision may be determined not only by the stereoscopic intensity but also by the determination based on the camera shake correction amount as described in the second embodiment.

<Fifth Embodiment>

The display device includes a separation unit 51, a decoding unit 52, a 3D control information analysis unit 53, a display control unit 54, an image conversion unit 55, a switch 56, and a display unit 57. And it is an apparatus which displays the image data from the said imaging device, or the image data from the recording medium which recorded the image data.

  The separation unit 51 separates multiplexed data, which is output data of the imaging device, into encoded image data and 3D control information data. The decoding unit 52 decodes the encoded image data to restore the image data. On the other hand, the 3D control information analysis unit 53 analyzes the 3D control information, and obtains the three-dimensional intensity, the standing subject distance, forced 2D display, and the like, if present, in addition to the parameters that are image format information. The image conversion unit 55 converts the decoded 3D image into a display format suitable for the display unit 57 based on the parameters and 2D / 3D display switching input from the display control unit 54. When the display switching is 2D display, the 3D image is converted into a 2D image.

The display control unit 54 selects either 3D display or 2D display based on the subject distance, the 2D forced display, and the three-dimensional strength input from the 3D control information analysis unit 53. Display switching may be set to 2D display in the following cases.
(A) When the solid intensity is larger than a predetermined value (b) When 2D display is specified by forced 2D display (c) The subject distance is closer than the first predetermined distance or from the second predetermined distance In this way, the image data can be automatically displayed in the optimum display form.
