METHOD FOR DISPLAYING LIVE VIEW FOR STEREOSCOPIC CAMERA USING Stereoscopic Camera

The present invention relates to a live view image in a stereoscopic camera.

As the interest in stereoscopic image service is getting more and more popular, devices for providing stereoscopic image are being continuously developed. Among such methods of implementing stereoscopic images, there is a stereoscopic method.

The basic principle of the stereoscopic method is that images arranged in such a manner that the left and right eyes of a person are orthogonal to each other are separated and inputted, and stereoscopic images are generated by combining images inputted from the left eye and right eye respectively in the human brain. In this case, the fact that the images are arranged to be orthogonal to each other means that the respective images do not interfere with each other.

1 is an exemplary view illustrating a stereoscopic image display device and a stereoscopic image camera.

As can be seen from FIG. 1 (a), a stereoscopic image display device is shown.

The method of implementing the stereoscopic image display device can be largely divided into a spectacle method and a non-spectacle method.

The spectacle method includes a polarization method, a time-sequential method, and a spectral method.

First, the polarization system separates each image using a polarizing filter. That is, by applying a polarization filter orthogonal to the left eye image and the right eye image, different images filtered by the polarization filter are input to the right and left eyes.

Next, the time division method alternately displays left and right images, and active glasses worn by the user are synchronized with images alternately displayed, thereby separating each image. That is, when the images are alternately displayed, the shutter of the active eyeglasses synchronized with the images alternately displays the left and right images by separating the right and left images by opening only the field of view in which the corresponding image is to be input and blocking the other fields of view.

Finally, the spectral method is a method of projecting left and right images through a spectral filter having a spectral band in which RGB spectrums do not overlap each other. With respect to the projected left and right images, the user wears passive glasses equipped with a spectral filter passing through only the spectral region set for the left and right images, thereby receiving the left and right images separately.

On the other hand, the non-eyeglass system has a retrospective eyeglass system. The above-mentioned multi-view glasses system includes a parallax barrier system and a lenticular lens system.

The Parental Barrier scheme applies a barrier to the display, wherein the barrier consists of vertical lines, and there is a slit between the vertical lines. And the left eye makes the parallax in the right eye by the slit.

The lenticular method arranges the refined small lenses on the display on the display so that the images are refracted by the small lenses to show different images on the left and right eyes.

On the other hand, such a 3D or stereoscopic display device has a limitation in that the diffusion of 3D contents or contents having a stereoscopic effect does not spread quickly.

1 (b) shows a camera capable of producing 3D or stereoscopic images.

As shown in FIG. 1 (b), a camera capable of producing a 3D or stereoscopic image captures each image from two camera lenses using the stereoscopic method, thereby generating a stereoscopic image.

Many such 3D cameras are being developed, and products are being released.

However, it is unfamiliar to make 3D or stereoscopic images for the general user. In particular, 3D or stereoscopic images are not yet familiar to the user, so the need to purchase 3D or stereoscopic cameras is not so great.

The first object located closer to the convergence point may be displayed above the plane and the second object which is farther from the convergence point may be displayed while being hidden from the plane.

The method includes receiving an operation input for the guide; And adjusting a convergence point between the plurality of optical lenses according to the manipulation input. And updating and displaying the position of the guide on the image in accordance with the adjustment of the convergence point.

2 shows the outline of an electronic device according to the present invention.

As can be seen with reference to FIG. 2, the electronic device 100 is illustrated as an exemplary portable terminal. The portable terminal may be one of a camera, a mobile communication terminal, a multimedia playback terminal, and a tablet terminal. More specifically, the portable terminal may be a mobile terminal, a personal digital assistant (PDA), a smart phone, a portable multimedia player (PMP), a notebook computer, a tablet PC (Tablet PC).

However, the electronic device 100 may be a non-portable terminal such as an Internet Protocol Television (IPTV) terminal, a television, a 3D television, a video device, a telematics terminal, or a vehicle installation navigation terminal have.

The electronic device may include a camera unit 121 and a display unit 151 as shown in FIG. The display unit 151 is mounted on the front face of the portable terminal and the camera unit 121 is mounted on the rear face of the portable terminal as shown in FIG. . Alternatively, the camera unit 121 may be mounted on the front surface of the portable terminal.

The camera unit 121 may include at least one pair of optical lenses 121a and 121b spaced apart from each other as shown in FIG. The camera unit 121 may also be referred to as a stereo camera or a stereoscopic camera. At this time, the fixed horizontal interval may be set considering the distance between two eyes of a general person.

A method of providing a live view in the electronic apparatus 100 having the first and second optical lenses 121a and 121b will now be described.

3 is a flowchart illustrating a live video providing method according to the first embodiment of the present invention.

First, an image obtained through the plurality of optical lenses is processed (S110). Processing the image means converting an image obtained through the plurality of optical lenses into an electrical signal through an image sensor or a CMOS sensor, and signal processing the electrical signal.

Then, the processed image is displayed on the display unit 151 for live view (S120).

At this time, a guide corresponding to the convergence point between the plurality of optical lenses is displayed together with the image for the live view (S130). Convergence point refers to the point where the 3D sensation is zero. This will be described in more detail with reference to FIGS. 4 to 8. FIG.

FIG. 4 is an example for understanding understanding of the convergence point, FIG. 5 is another example for understanding the convergence point, and FIG. 6 is another example for understanding the convergence point. And FIG. 7 is another exemplary diagram for explaining the convergence point.

First, referring to FIG. 4, a point at which the focal lengths of the first optical lens and the second optical lens coincide with each other is a convergence point. Such a convergence point can be adjusted in distance as shown in Fig. 4 (a). Therefore, when the main subject, which is an object to be photographed, is set to the convergence point, the main subject is photographed with no stereoscopic effect, that is, with a degree of zero.

Referring to Fig. 4 (b), assume that there are a hexahedron and a cylinder, and that it is photographed. If the hexahedron and the cylinder are photographed after the convergence point is aligned with a point farther than the hexahedron, the cube is positioned in front of the background with a stereoscopic view, and the cylinder is expressed in front of the cube with a cubic feeling.

Referring to FIG. 5, when the convergence point is adjusted to fit the hexahedron, the hexahedron is represented as 2D without stereoscopic view, while the cylindrical is stereoscopic as if it is positioned ahead of the hexahedron Can be expressed.

As another example, referring to FIG. 6, when the convergence point is adjusted so that the cylinder is photographed after being aligned with the cylinder, the cylinder is expressed in 2D without stereoscopic effect, while the cubic body is stereoscopically Can be expressed.

On the other hand, referring to Fig. 7 (a), it is assumed that a cylinder is positioned behind the hexahedron, and a cylinder is located after the hexahedron. At this time, as shown in Fig. 7 (b), when the convergence point is aligned with the cylinder at the front, the front cylinder is represented by 2D, while the cube has a cubic feeling and is farther away from the front cylinder And the rear cylinder is expressed as having a cubic shape and being farther than the cube.

In this way, the stereoscopic effect of the image is different depending on which object the convergence point is set to. In other words, stereoscopic viewing can be controlled in stereoscopic images by adjusting the conjugation point, as in the case of a conventional photography technique.

However, conventional stereo-scopic cameras have not been easy to control such convergence points. Therefore, it was not easy for the general user to photograph the image by adjusting the congence point.

Therefore, the first embodiment of the present invention provides the convergence point through the guide when the user photographs the stereoscopic image, thereby allowing the user to easily adjust the convergence point.

FIG. 8 is a view illustrating an example of a live view image displayed according to the procedure shown in FIG.

As can be seen from FIG. 8, the guide corresponding to the convergence point between the plurality of optical lenses may be displayed as a plane having a predetermined transparency.

The plane may be displayed to have a depth sense corresponding to the distance to the convergence point. In other words, as shown in Fig. 8, when there is a horizontal axis x, a vertical axis y, and a depth axis z, the plane is displayed on the z axis at a depth corresponding to the distance to the convergence point.

A hexahedron located closer to the convergence point may be displayed on the plane, and a second object that is distant from the convergence point may be displayed on the plane.

The user can manipulate the distance of the convergence point. That is, the electronic device may include a button for operating the convergence point, or may display a button for operating the confidential point on the display unit.

 When the manipulation signal for the convergence point is input from the user, the electronic device can adjust the convergence point between the plurality of optical lenses according to the manipulation input.

The electronic device can update and display the position of the guide on the live view image in accordance with the adjustment of the convergence point.

For example, when the user moves the convergence point more closely, the guide in FIG. 8, that is, the plane having predetermined transparency is displayed in the + direction along the z axis. On the other hand, when the user moves the convergence point more distantly, the guide, that is, a plane having a predetermined transparency is moved along the z axis. Direction and displayed.

By providing the guide screen for the convergence point to the live view image, the user can more easily adjust the convergence point to the desired object, and the stereoscopic view of the stereoscopic image can be adjusted as desired.

9 is a flowchart illustrating a live video providing method according to a second embodiment of the present invention.

Referring to FIG. 9, an image obtained through the plurality of optical lenses is processed (S210). Processing the image means converting an image obtained through the plurality of optical lenses into an electrical signal through an image sensor or a CMOS sensor, and signal processing the electrical signal.

Then, the processed image is displayed on the display unit 151 for live view (S220).

The live view image may be the same as the screen shown on the left side of FIG. 10 (a). At this time, referring to the left side of FIG. 10 (a), there are a plurality of subjects on the scene. At this time, the plurality of subjects are located at different distances as shown in the right side of FIG. 10 (a). As such, when a plurality of subjects are located at different distances, any subject may be displayed with a too large stereoscopic effect unless the convergence point is appropriately adjusted. That is, a subject located far away from the reference line of the convergence point can be expressed with a very large stereoscopic effect. However, a general user may not know how much stereoscopic effect should be taken without special knowledge and experience.

Accordingly, in the image for the live view, a guide indicating whether at least one subject is located forward or backward is displayed based on the convergence point between the plurality of optical lenses (S230). Thus, a guide is provided which indicates whether the subjects are located forward or backward with respect to the convergence point.

To this end, as shown in the left side of FIG. 10 (b), the electronic device 100 can measure the distance to the subject. To this end, the electronic device 100 may include a distance measuring sensor. The distance measuring sensor may include an infrared sensor.

Alternatively, the electronic device 100 may calculate a disparity in an image obtained through the plurality of cameras without the assistance of the distance measuring sensor, and calculate a disparity between each object You can get a distance.

10 (b), the electronic device 100 displays a guide screen indicating whether at least one subject is located at the front side or rear side based on the convergence point between the plurality of optical lenses It can be displayed together with the view image.

The guide screen may be displayed at a time of looking downward from the sky, for example, a Bird View time.

10 (b), the guide screen includes a first line (i.e., a convergence point reference line) indicating the convergence point, a second line (i.e., a front limit line) indicating a forward limit point based on the convergence point, , And a third line representing a rear limit point based on the convergence point (i.e., a rear limit line).

At this time, the electronic device 100 may automatically adjust the convergence point while providing the guide screen. That is, the electronic device 100 may provide an auto-convergence function.

In other words, when the electronic apparatus 100 has a plurality of subjects on the scene, it calculates the distance to each subject, and automatically adjusts the convergence point so that the main subject and the auxiliary subject are expressed with proper stereoscopic effect. Such an automatic adjustment function can be automatically performed when an arbitrary subject is located at a greater distance than the above-described rear limit line or the front limit line. Alternatively, such an automatic adjustment function may be performed in order to cause the main subject to be displayed with a constant dimensional feeling.

Alternatively, the electronic device 100 may provide the guide screen and allow the user to adjust the convergence point through the guide screen.

To this end, the electronic device 100 may include a button for operating the convergence point, or may display a button for operating the convergence point on the display unit. Alternatively, adjustment of the convergence point may be accomplished by touching and dragging the convergence point baseline. Alternatively, adjustment of the convergence point may be accomplished by touching and dragging the front limit line or the back limit line. Alternatively, the adjustment of the convergence point may be made by touching the object in the screen.

If an operation input to the guide is received from a user, the electronic apparatus can move the subject forward or backward in accordance with the operation input to display the converged point.

The method described above can be implemented in a recording medium that can be read by a computer or similar device using, for example, software, hardware, or a combination thereof.

According to a hardware implementation, the methods described so far can be applied to various types of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays processors, controllers, micro-controllers, microprocessors, and other electronic units for performing other functions.

According to a software implementation, the procedures and functions described herein may be implemented in separate software modules. The software modules may be implemented in software code written in a suitable programming language. The software code may be stored in a storage unit and executed by a processor.
