Hereinafter, a stereoscopic image generation system according to an embodiment of the present invention will be described with reference to FIG. 1.

1 is a conceptual block diagram of a stereoscopic image generating system according to an embodiment of the present invention.

Referring to FIG. 1, the stereoscopic image generating system 100 includes a receiver 110 and a converter 120.

As used herein, the term 'part' or 'module' refers to software or a hardware component such as an FPGA or an ASIC, and the 'part' or 'module' performs certain roles. However, " part " or " module " is not meant to be limited to software or hardware. The term " part " or " module " may be configured to reside on an addressable storage medium and configured to play one or more processors. Thus, by way of example, 'a' or 'module' is intended to be broadly interpreted as encompassing any type of process, including features such as software components, object-oriented software components, class components and task components, Microcode, circuitry, data, databases, data structures, tables, arrays, and variables, as used herein, Or " modules " or " modules " or " modules " or " modules " Can be further separated.

The receiver 110 may receive the input image II and provide it to the converter 120. In some embodiments of the present disclosure, the input image II provided to the receiver 110 may be, for example, image content. Here, the image content may mean that an image or an image is produced in a content form through digital or analog encoding.

In some embodiments of the present invention, such image content may be a 2D image, or may be a 3D image (eg, an image in which content is displayed in both a left eye image and a right eye image). Also, in some other embodiments of the present disclosure, the input image II provided to the receiver 110 may be an image or an image of the object itself, not image content. That is, in the present embodiment, the type of the input image II provided to the receiver 110 is not limited.

The receiver 110 may receive an input image II and perform a predetermined operation on the input image II in the process of providing the input image II to the converter 120. For example, in some embodiments of the present disclosure, the receiver 110 may convert the format of the input image II and provide it to the converter 120. For example, in some other embodiments of the present disclosure, the receiver 110 may adjust the size of the input image II and provide the same to the converter 120. That is, the receiving unit 110 may perform a predetermined preprocessing operation that may assist the operation of the converting unit 120.

Meanwhile, although FIG. 1 illustrates that the receiver 110 is included in the 3D image generating system 100, the present invention is not limited thereto. That is, the receiver 110 may be omitted as necessary. In this case, the input image II may be provided directly to the converter 120 without passing through the receiver 110.

The converter 120 may convert the input image II received from the receiver 110 into a stereoscopic image SI in which the first frame section and the second frame section are alternately repeated. That is, in the present embodiment, the type of the input image II provided to the converter 120 is not limited, but the image output from the converter 120 repeats the first frame section and the second frame section alternately. The stereoscopic image SI becomes.

Hereinafter, the stereoscopic image SI output by the converter 120 will be described in more detail with reference to FIGS. 2 and 3.

2 and 3 are views for explaining a stereoscopic image generated by the stereoscopic image generating system according to an embodiment of the present invention.

1 to 3, the stereoscopic image SI output from the converter 120 includes a left eye image LI and a right eye image RI, and includes a left eye in a first frame section FRAME SECTION 1. The input image II is displayed on the image LI, and the input image II is shadowed on the right eye image RI. In the stereoscopic image SI, the input image II is displayed on the right eye image RI and the input image II is shaded on the left eye image LI in the second frame section FRAME SECTION 2. .

Specifically, referring to FIGS. 2 and 3, in the stereoscopic image SI output by the converter 120, as illustrated, the first frame section FRAME SECTION 1 and the second frame section FRAME SECTION 2 are illustrated. This is repeated alternately. At this time, in the first frame section FRAME SECTION 1, the input image II is displayed on the left eye image LI (in Fig. 3, for example, a triangle is displayed on the left eye image LI), The input image II is shadowed and displayed on the right eye image RI (in FIGS. 2 and 3, the right eye image RI is displayed in a darkened state). In the second frame section FRAME SECTION 2, the input image II is displayed on the right eye image RI (in FIG. 3, a rectangle different from the frame output before the right eye image RI is displayed. It means that the input image (II) changes as time passes), and the input image (II) is shaded and displayed on the left eye image (LI) in FIG. 2 and FIG. 3. Are displayed in the

In this case, the first frame section FRAME SECTION 1 may include a plurality of frames, and the second frame section FRAME SECTION 2 may also include a plurality of frames. That is, the first frame section FRAME SECTION 1 is a section in which the input image II is displayed on the left eye image LI, and the plurality of frames displayed by darkening the input image II on the right eye image RI are displayed. In the second frame section FRAME SECTION 2, the input image II is displayed on the right eye image RI, and the input image II is shadowed on the left eye image LI, and a plurality of displayed frames are collected. It may be a section.

The configuration of the stereoscopic image SI output by the converting unit 120 according to the present embodiment is the same because it is possible to reduce eye fatigue by watching the stereoscopic image SI.

As a general stereoscopic image is viewed, the fatigue of the eye may be understood to be caused because the focal point of the lens and the direction of the eye are different from those of the actual object. That is, when viewing a stereoscopic image, the focus of the lens is adjusted to the screen on which the image is displayed, but it is known that the eye fatigue is increased because the direction of the eyeball is aligned behind the screen.

However, in the stereoscopic image SI according to the present exemplary embodiment, either one of the left eye image LI and the right eye image RI is shaded and displayed as shown. Therefore, when viewing the stereoscopic image SI according to the present embodiment, since the lens focal point of the viewer and the direction of the eye may be the same, eye fatigue may be reduced.

Furthermore, when viewing the stereoscopic image (SI) according to the present embodiment, an effective treatment for strabismus, which is one of eye disorders, may be possible. 3D Asthenopia, which can occur when viewing stereoscopic images for a long time, can be caused by similar causes (a problem in which the focus of the lens and the direction of the eye are different from those of viewing an actual object). Therefore, the stereoscopic image SI according to the present exemplary embodiment may be effective not only for 3D Asthenopia of the eye but also for strabismus.

Meanwhile, in some embodiments of the present invention, the time T1 for which the first frame section FRAME SECTION 1 lasts may be, for example, 1 to 3 minutes. In addition, the time T2 for which the second frame section FRAME SECTION 2 lasts may be, for example, 1 to 3 minutes. The reason why the first frame section FRAME SECTION 1 and the second frame section FRAME SECTION 2 are maintained for 1 to 3 minutes is to maximize the effect of reducing eye fatigue due to viewing stereoscopic images.

For example, according to the present exemplary embodiment, when a 3 minute advertisement image is generated, the stereoscopic image (eg, the first frame section FRAME SECTION 1 and the second frame section FRAME SECTION 2) may be continued for 1.5 minutes. SI), wherein the first frame section FRAME SECTION 1 lasts for 1 minute, the second frame section FRAME SECTION 2 lasts for 1 minute, and the first frame section FRAME SECTION 1 lasts for 1 minute. You may.

Although not shown in detail in the drawings, the background of the stereoscopic image SI according to the present exemplary embodiment may be configured as a green series to minimize eye fatigue.

Meanwhile, in another embodiment of the present invention, the time T1 for which the first frame section FRAME SECTION 1 lasts and the time T2 for the second frame section FRAME SECTION 2 lasting may be different from each other. As such, when the time T1 for the duration of the first frame section FRAME 1 and the time T2 for the duration of the second frame section FRAME 2 are different, the fatigue reduction effect on the left eye and the right eye The effects of fatigue can be different. Therefore, when one of the left eye and the right eye feels more fatigue, the time T1 for the duration of the first frame section FRAME SECTION 1 and the time T2 for the second frame section FRAME SECTION 2 last. ), Different eye drops can reduce eye fatigue more effectively.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
