However, conventionally, the imaging of the stereoscopic image displayed on the display screen by the imaging device has not been considered. For this reason, when image | photographing the display screen which displays a stereoscopic image with an imaging device, there existed a problem that the image which deteriorated by mixing the image for a left eye and the image for a right eye has been taken.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a novel and improved imaging apparatus, an imaging system, and an imaging method capable of imaging without deteriorating a stereoscopic image displayed on a display screen of a display device. It is in doing it.

EMBODIMENT OF THE INVENTION Embodiment of this invention is described in detail, referring an accompanying drawing below. In addition, in this specification and drawing, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol about the component which has substantially the same functional structure.

<Overview of display system>

First, the outline | summary of the display system 1 is demonstrated with reference to FIG. 1 is a block diagram illustrating a display system 1.

The display system 1 can display a three-dimensional image in addition to the two-dimensional image. The display system 1 is a system which can perceive a 3D image to be displayed to a user, and can image a 3D image to be displayed, without degrading image quality. The display system 1 includes a display device 10, glasses 20 with a shutter, and an imaging device 100.

The display apparatus 10 is a display, for example, and displays a two-dimensional image and a three-dimensional image. This display device 10 has a display screen 11 and a transmitter 12. When displaying a three-dimensional image, on the display screen 11, the left eye image and the right eye image corresponding to binocular disparity are alternately displayed in units of frames. The transmitter 12 transmits display switching signals of the left eye image and the right eye image constituting the three-dimensional image to the glasses 20 with the shutter or the imaging apparatus 100. This display changeover signal is generated inside the display device 10 and transmitted by wireless communication such as infrared communication.

The shutter-mounted glasses 20 are for the user to perceive a three-dimensional image displayed on the display screen 11 of the display device 10. The glasses 20 with a shutter have a receiver 21 and a liquid crystal shutter 22. The receiver 21 receives the display changeover signal sent by the transmitter 12 of the display apparatus 10. The liquid crystal shutter 22 has two liquid crystal shutters that can be opened and closed, and the opening and closing operations of the two liquid crystal shutters are controlled based on the display change signal received by the receiver 21. Specifically, the opening and closing operations of the two liquid crystal shutters are controlled so that the switching timing of the two liquid crystal shutters is synchronized with the display switching timing of the display screen.

Here, the display of the left eye image and the right eye image will be described with reference to FIG. 2. 2 is a view for explaining the relationship between the display of the left eye image and the right eye image, and the shutter operation of the glasses 20 with a shutter. In FIG. 2, the left eye image L and the right eye image R are alternately displayed. The two liquid crystal shutters 22a and 22b are opened and closed in accordance with the display of the left eye image L and the right eye image R. FIG. For example, when the liquid crystal shutter left eye image of reference numeral 22a is displayed, it is in an open state, and the liquid crystal shutter of reference number 22b is in an open state when the image for right eyes is displayed. In this way, by controlling the opening and closing operations of the two liquid crystal shutters 22a and 22b, a user who wears the glasses 20 with the shutter and views the display screen 11 can perceive a three-dimensional image.

The imaging device 100 picks up a two-dimensional image or a three-dimensional image displayed on the display screen 11. In addition, the imaging apparatus 100 may communicate with the display apparatus 10 by infrared rays or the like. When imaging the three-dimensional image, the imaging device 100 separates and captures the left eye image and the right eye image based on the display switching signal transmitted from the transmission unit 12. The detailed structure of this imaging device 100 is mentioned later.

In addition, although the display switch signal transmitted to the imaging device 100 was the same as the display switch signal transmitted to the eyeglasses 20 with a shutter in the above, it is not limited to this, It may be different. However, when the display switching signal transmitted to the glasses 20 with a shutter and the imaging device 100 are the same, the display device 10 does not need to generate another signal, which can contribute to the simplification of the system.

In addition, although the display system 1 included the spectacles 20 with a shutter, it is not limited to this, It is good also as not including the spectacles 20 with a shutter. The combination of the display device 10 and the imaging device 100 of this embodiment corresponds to an imaging system.

<Configuration of the imaging device>

Next, with reference to FIG. 3, the structure of the imaging device 100 is demonstrated. 3 is a block diagram showing an internal configuration of the imaging apparatus 100.

 The imaging device 100 is, for example, a digital camera capable of capturing still images or a video camera capable of capturing moving images. Of course, the digital camera may have a configuration of capturing both still and moving images.

As shown in FIG. 3, the imaging device 100 includes a lens 114 and a shutter 114 as an example of a shutter unit, an imaging element 116 as an example of an imaging unit, an image signal processor 120, and a compression processor. 130, the CPU 140, which is an example of the controller, the memory 142, the monitor 150, the recording medium 160, which is an example of the storage unit, the operation unit 170, and the communication unit, which is an example of the receiver ( 180) and the like.

The lens 112 is an optical system that forms external optical information onto the imaging device 116, and transmits light from a subject to the imaging device 116. Although not shown, the lens 112 is formed of, for example, a zoom lens, an aperture, a focus lens, and the like. A zoom lens changes the angle of view by changing the focal length. The iris adjusts the amount of light transmitted. The focus lens moves in the optical axis direction to focus the subject image on the imaging surface of the imaging device 116.

The shutter 114 is for controlling the exposure of the imaging element 116. The shutter 114 is, for example, a mechanical shutter, and is configured to block light at the time of non-shooting so that the light reaches the imaging element 116 only at the time of shooting. In addition, the shutter 114 is not limited to a mechanical shutter but can also be configured as an electronic shutter. In addition, the driving timing of the shutter 114 is controlled to be synchronized with the display switching timing of the display screen 11 based on the display switching signal received from the display device 10.

The imaging element 116 is an example of a photoelectric conversion element, and is composed of a plurality of elements capable of photoelectric conversion for converting optical information incident through the lens 112 into an electrical signal. Each device generates an electrical signal according to the amount of light received. As the imaging device 116, a charge coupled device (CCD) image sensor, a complementary metal oxide semiconductor (CMOS) image sensor, or the like may be used.

The imaging element 116 further has a CDS / AMP unit and an A / D conversion unit. The CDS / AMP unit (Correlated Double Sampling / Amplifier) removes the reset noise and the amplifier noise included in the electrical signal output from the imaging element 116, and amplifies the electrical signal to an arbitrary level. The A / D converter generates a digital signal by digitally converting the electrical signal output from the CDS / AMP unit. The A / D converter outputs the generated digital signal to the image signal processor 120.

The image signal processing unit 120 adjusts the gain correction and the white balance of the amount of light with respect to the raw data of the image obtained from the imaging element 116. The image signal processing unit 120 also performs processing such as pixel defect correction, black level correction, shading correction, and the like of the imaging element 116.

The compression processing unit 130 compresses the image in which the image signal processing unit 120 has gain correction or adjustment of the white balance of the amount of light into image data of an appropriate format. The compression processing unit 130 performs compression encoding processing by, for example, a coding method of still picture such as a JPEG (Joint Photographic Experts Group) standard. In addition, the compression processing unit 130 performs encoding processing, for example, in an MPEG format to generate stream data in which a plurality of image frames are collected as one file.

The CPU 140 functions as a calculation processing device and a control device by a program, and controls the processing of each component included in the imaging device 100. The CPU 140 controls the opening / closing operation (driving timing) of the shutter 114, for example. The memory 142 stores a program executed by the CPU 140, various data (for example, image data), and the like.

The monitor 150 displays an image. The image displayed by the monitor 150 is, for example, an image before shooting (live view display) read out from the memory 142, various setting screens of the imaging device 100, an image captured and recorded, and the like. The monitor 150 is, for example, a liquid crystal display, an organic electroluminescence display (OLED), or the like.

The recording medium 160 is a memory card in this embodiment, and records the photographed image data. The recording medium 160 is configured to be detachable from the imaging device 100. In addition, the recording medium 160 is not limited to a memory card, but may be formed of an optical disc (CD, DVD, Blu-ray, etc.), a magneto-optical disc, or the like.

The operation unit 170 is for performing the operation of the imaging device 100 or for performing various settings during shooting. The operation unit 170 includes a power button, a selection button for selecting a shooting mode, a shutter button for starting a photographing operation of a subject, a cross key, and the like.

The communication unit 180 communicates with the display device 10 by wireless communication (eg, infrared communication). The communication unit 180 receives a display change signal transmitted from the transmitter 12. In addition, the communication unit 180 is not limited to wireless communication, and may be configured to perform wired communication with the display device 10 through a cable or the like.

<Operation of the imaging device>

When the imaging device 100 according to the present embodiment photographs the display screen 11 displaying the three-dimensional image, the image for the left eye constituting the three-dimensional image is based on the display change signal transmitted from the transmission unit 12. The right eye image is separated and imaged. Specifically, the imaging device 100 synchronizes the driving timing of the shutter 114 with the display switching timing of the left eye image and the right eye image based on the received display switching signal, so that the imaging element 116 receives the left eye. The image for the eye and the image for the right eye are separated and imaged.

Thereby, it can prevent that the deterioration image of the state which mixed the left eye image and the right eye image as shown in FIG. 4 is taken. By separating the left eye image and the right eye image, the left eye image and the right eye image picked up during reproduction of the three-dimensional image can be reproduced while maintaining the image quality. 4 is a figure which shows the state where the left eye image and the right eye image were mixed and image | photographed.

In the following, the specific operation of the imaging device 100 when separating and imaging the left eye image and the right eye image when the three-dimensional image is displayed will be described. In addition, the imaging device 100 according to the present embodiment can capture still images or moving images. Therefore, after explaining the operation of the imaging device 100 when shooting a three-dimensional image as a still image, the operation of the imaging device 100 when shooting a three-dimensional image as a moving image will be described.

<Operation of the imaging device at the time of still image shooting>

FIG. 5 is a flowchart for explaining the operation of the imaging device 100 when capturing a three-dimensional image displayed on the display screen 11 as a still image.

The flowchart of FIG. 5 starts when the display apparatus 10 alternately displays the left eye image and the right eye image on the display screen 11 in frame units, and displays a three-dimensional image. In addition, it is assumed that the transmission unit 12 of the display device 10 is transmitting the display switching signal in accordance with the display of the three-dimensional image. This display changeover signal is a signal that the glasses 20 with a shutter and the imaging device 100 can receive.

First, the communication unit 180 receives the display changeover signal transmitted from the transmission unit 12 (step S2). In addition, the communication unit 180 continuously receives the display change signal during communication with the display device 10.

Next, the CPU 140 determines whether or not the shutter button of the operation unit 170 has been pressed for still image shooting (step S4). When the shutter button is pressed by the user (step S4: YES), the CPU 140 controls the driving of the shutter 114, so that one pair of a left eye image and a right eye image on the imaging element 116 are provided. The image of one side (herein, it is called an image for a right eye) is image | photographed in the image (step S6).

Specifically, the CPU 140 controls the drive timing of the shutter 114 to synchronize with the display switching timing of the left eye image and the right eye image. Here, the shutter 114 is opened at the time of the display switching timing from the left eye image immediately after the shutter button is pressed to the right eye image, and the imaging device 116 displays the right eye image displayed on the display screen 11. Image only.

The CPU 140 then opens the shutter 114 at the time of display switching timing of the left eye image from the right eye image, and the imaging element 116 displays the left eye image displayed on the display screen 11. Only an image is picked up (step S8). In this way, when the shutter button is pressed, the left eye image and the right eye image are imaged separately, so that the state where the captured image data is mixed with the left eye image and the right eye image can be avoided.

The image signal processing unit 120 adjusts the left eye image and the right eye image which are separated and photographed (step S10). For example, when there is a difference in the brightness of the left eye image and the right eye image depending on the shooting conditions, the image signal processing unit 120 adjusts the two images. As the adjustment method, for example, a method of multiplying the gain according to the energy ratio of the entire image screen can be applied. In addition, instead of the entire screen, an average of, for example, a range of 30% may be used at the center of the surface, in which case the processing time can be shortened.

Subsequently, the CPU 140 separates the three-dimensional image displayed on the display screen 11 into a left eye image and a right eye image, and stores them in the recording medium 160 (step S12). By separating and storing in this way, there is no fear that image quality will deteriorate during reproduction as a three-dimensional image. In addition, since one side of the left eye image and the right eye image stored separately can be used as a two-dimensional image, the use range of the captured three-dimensional image can be expanded.

By separating and storing the left eye image and the right eye image, the processing of still image shooting is completed. In addition, the image adjustment of step S10 mentioned above may be performed independently, after storing the left eye image and the right eye image in the recording medium 160. FIG.

<Operation of the imaging device at the time of video shooting>

6 is a flowchart for explaining the operation of the imaging device 100 when photographing a three-dimensional image displayed on the display screen 11 as a still image.

The flowchart of FIG. 6 starts when the display apparatus 10 displays the left eye image and the right eye image alternately on a display screen 11 in frame units, and displays a three-dimensional image. In addition, it is assumed that the transmission unit 12 of the display device 10 is transmitting the display switching signal in accordance with the display of the three-dimensional image.

The communication unit 180 receives the display changeover signal sent by the transmission unit 12 (step S102). Subsequently, the CPU 140 determines whether or not the shutter button of the operation unit 170 has been pressed for moving picture photographing (step S104). When the shutter button is pressed by the user (step S104: YES), the CPU 140 controls the driving timing of the shutter 114, and the left eye image constituting the three-dimensional image in the image pickup device 116. The right eye image is separated and imaged (steps S106 and S108). Thereby, even at the time of moving picture pick-up, the left eye image and the right eye image which comprise the three-dimensional image displayed on the display apparatus 10 can be image | photographed separately.

6 is the same as step S6-S12 of FIG. 5, detailed description is abbreviate | omitted.

When the left eye image and the right eye image are separated and stored in the recording medium 160 in step S112, the CPU 140 determines whether or not to end the moving image photographing (step S114). Here, the end of the moving picture photographing may be executed in accordance with the end operation by the user, but may be executed when the display of the three-dimensional image by the display device 10 ends.

When moving picture shooting continues (step S114: NO), the processes of steps S106 to S112 are repeated. That is, at the time of moving picture pick-up, the imaging device 100 separates a left eye image and a right eye image, and continues imaging. On the other hand, when the display of the three-dimensional image ends and the moving image shooting ends (step S114: YES), the CPU 140 captures a single image from the three-dimensional imaging mode in which the left eye image and the right eye image are separated and picked up. The process shifts to the two-dimensional imaging mode in which imaging is performed (step S116). This eliminates the need for the user to switch modes for subsequent normal imaging.

<Efficacy of the imaging device according to the present embodiment>

As described above, according to the imaging device 100 according to the present embodiment, when photographing the display screen 11 displaying a three-dimensional image, the left eye image and the right eye image constituting the three-dimensional image are separated and picked up. By doing so, it is possible to prevent the left eye image and the right eye image from being mixed and photographing the deteriorated image.

In addition, by separating the left eye image and the right eye image and storing them in the recording medium 160, the left eye image or the right eye image can be extracted from the photographed three-dimensional image and used as a two-dimensional image. In addition, since the driving of the shutter 114 is controlled by using the display change signal transmitted to the glasses 20 with the shutter, it is not necessary to change the configuration of the display device 10, and the conventional system can be effectively utilized.

In addition, although the display apparatus 10 supposes that the left eye image and the right eye image are sequentially switched, it is not limited to this. For example, it can also be comprised by displaying a black image in the middle of switching a display from a left eye image (right eye) image to a right eye image (left eye) image. Even in such a case, the image for the right eye and the image for the left eye may be separated and captured based on the display switching signal.
