Problems solved by technology

In this case, for example, when the display device does not have a stereoscopic function, or even if the display device has a stereoscopic function, the viewer does not wear a device for stereoscopic viewing, such as stereoscopic glasses, etc. to view the content. In this case, the image to be viewed is a double image in which the image for the right eye and the image for the left eye are superimposed, and it is an image that is difficult to view normally
Therefore, the 2D-3D conversion function prevents content owners from claiming ownership of content displayed normally and alerting them to copyright infringement such as illegal imitation.

Embodiment 1

[0032] The image processing device of embodiment 1, such as figure 2 As shown, it is applicable to a DVD playback device 20 having a DVD playback function and a function of converting a DVD playback image into an analog 3D image.

[0033]The video signal 14 is encoded and recorded on the reproduced DVD. The DVD reproduced signal 11 output from the DVD signal reading device 21 is input to the decoder 12, decoded into an image signal 14, and output. The output image signal 14 is input to a 2D-3D converter 15 that converts a non-stereoscopic (2D) image into an analog stereoscopic (3D) image. Then, the 2D-3D converter 15 generates and outputs a left analog stereoscopic image signal 16 and a right analog stereoscopic image signal 17 . The two analog stereoscopic image signals 16 and 17 are input to the 3D display converter 28 , converted into a 3D image format signal 29 in a signal format for transmission to the stereoscopic display device 30 , and output from the DVD reproducti...

Embodiment 2

[0036] In the DVD reproducing apparatus 20 of Embodiment 1, as figure 2 As shown, an example is shown in which the subtitle information signal 18 and the playback operation restriction signal 13 are output from the decoder 12 , and logical operation with the 2D-3D control signal 33 is performed in the 2D-3D converter 15 . However, for example, this logical operation may be performed inside the decoder 12 , and only a signal for switching control of 2D-3D conversion resulting from the result may be input to the 2D-3D converter 15 .

[0037] In the DVD generating device 20a of Embodiment 2, as Figure 4 As shown, the 2D-3D control signal 33 is directly input to the decoder 12, and the subtitle information signal indicating the presence or absence of subtitles detected inside the decoder 12 is compared with the navigation command information detected inside the decoder 12. The logical operation of the signal representing the regeneration operation restriction, that is, the rege...

Embodiment 3

[0039] In both the first and second embodiments, examples of DVD playback devices 20 and 20a including a DVD playback function and a function of converting a playback image into an analog 3D image are shown in the same body. In Example 3, such as Figure 5 As shown, a case where the system is separated into a DVD playback device 20b having a DVD playback function and a 2D-3D conversion device 34 having a function of converting a playback image into an analog 3D image will be described.

[0040] From the DVD reproduction device 20b, the image signal 14, the subtitle information signal 18, and the reproduction operation restriction signal 13 are input to the 2D-3D conversion device 34 via respective independent transmission lines. Like Embodiment 1 and Embodiment 2, the effectiveness of the 2D-3D conversion operation performed in the 2D-3D conversion device 34 is controlled by the result of the logical operation of the 2D-3D control signal 33, the subtitle information signal 18,...

Abstract

An image processing device comprises: a play operation limitation signal generation unit (12) which generates a play operation limitation signal which represents a play operation limitation of image data based on data which is appended to the image data; and a 2D-3D conversion apparatus (15) which converts the image data into a simulated 3D image. The 2D-3D conversion apparatus (15) controls enabling and disabling an operation which converts the image data from a 2D image to the simulated 3D image based on the play operation limitation signal.

Description

technical field [0001] The present invention relates to an image processing device having a function of converting a 2D image into a simulated 3D image. Background technique [0002] A pseudo-stereoscopic image generation device described in Patent Document 1 is known as an image processing device having a function of converting a non-stereoscopic (2D) image into a pseudo-stereoscopic (3D) image (2D-3D conversion function). [0003] In addition, as a well-known application example of the pseudo-stereoscopic image generation device described in Patent Document 1, a 3D image processor "IF-2D3D1" (Nippon Victory Corporation) for business use is known. [0004] By using these pseudo stereoscopic image generating devices described above, all 2D image signals can be processed into pseudo 3D images and displayed on a display device. [0005] As the content source of the image signal, the content source distributed through TV broadcasting, the Internet, etc., or the content source ...
