Description

How to display Live View video on a stereoscopic camera {METHOD FOR DISPLAYING LIVE VIEW FOR STEREOSCOPIC CAMERA}

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

Recently, as interest in stereoscopic image services is increasing, devices for providing stereoscopic images continue to be developed. One of the methods of implementing such a stereoscopic image is a stereoscopic method.

The basic principle of the stereoscopic method is to separate and input images arranged so that the left and right eyes of a person are orthogonal to each other, and a stereoscopic image is generated by combining images respectively input to the left and right eyes of the human brain. In this case, the images are arranged to be orthogonal to each other means that the images do not interfere with each other.

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

As can be seen with reference to FIG. 1A, a stereoscopic image display apparatus is shown.

Methods of implementing a stereoscopic image display apparatus may be largely divided into a glasses method and a glasses-free method.

The spectacles may be a polarization scheme, a time-sequential scheme, or a spectral scheme.

First, a polarization method separates each image using a polarization filter. That is, by applying polarization filters orthogonal to each other for the image using the left eye and the image for the right eye, different images filtered by the polarization filter are input to the left and right views.

Next, in the time division method, left and right images are alternately displayed, and active glasses worn by the user are synchronized with the alternately displayed images to separate each image. That is, when the images are displayed alternately, the shutter of the active glasses synchronized with the image is opened only when the corresponding image is to be input and the other view is blocked, thereby separating the left and right images.

Finally, the spectral method is a method of projecting left and right images through a spectral filter having spectral bands in which RGB spectra 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 only the spectral region set for the left and right images, thereby separating and inputting the left and right images.

On the other hand, there is a multi-view auto glasses method as the auto glasses-free method. The multi-view autostereoscopic method includes a Parallax Barrier method and a lenticular lens method.

The Ferrex barrier method applies a barrier to the display, which is composed of vertical lines, with a slit between the vertical lines. By the slit, the left eye creates a parallax in the right eye.

The lenticular method arranges the small lenses refined on the display on the display, and the image is refracted by the small lenses to display different images on the left and right eyes.

On the other hand, such a 3D or three-dimensional display device has a limitation because the spread of 3D content or content having a three-dimensional feeling is not rapidly spread.

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

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

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

As can be seen with reference to FIG. 2, the electronic device 100 is shown 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. It may be any one of (Tablet PC).

However, the electronic device 100 may be a non-portable terminal, such as an IPTV terminal, a television, a 3D television, an imaging device, a telematics terminal, or a vehicle installation navigation terminal. have.

As shown in the drawing, the electronic device may include a camera unit 121 and a display unit 151. When the electronic device 100 is a portable terminal, the display unit 151 is mounted on the front of the portable terminal, and the camera unit 121 is mounted on the rear of the portable terminal, as shown in FIG. Can be. Alternatively, the camera unit 121 may also be mounted on the front of the portable terminal.

The camera unit 121 may include at least one pair of optical lenses 121a and 121b spaced apart at horizontal intervals as shown. The camera unit 121 may also be called a stereo camera or a stereoscopic camera. In this case, the fixed horizontal interval may be set in consideration of the distance between two eyes of a general person.

As described above, a method of providing a live view in the electronic device 100 including the first and second optical lenses 121a and 121b will be described below.

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

First, an image acquired 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 processing the electrical signal.

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

In this case, the guide corresponding to the convergence point between the plurality of optical lenses is displayed on the image for the live view (S130). The convergence point refers to the point where the three-dimensional effect is zero. This will be described in more detail with reference to FIGS. 4 to 8.

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

First, as can be seen with reference 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. This convergence point can be adjusted in distance as shown in FIG. Therefore, when the main subject, which is a photographing target, is converged to the point of convergence, the main subject is photographed without the stereoscopic sense, that is, the degree becomes zero.

Referring to FIG. 4 (b), suppose that a cube and a cylinder are photographed. When the convergence point is set to a point farther than the cube, and the cube and the cylinder are photographed, the cube is positioned in front of the background with a three-dimensional view, and the cylinder is expressed as being in front of the cube with a three-dimensional appearance.

On the other hand, referring to Figure 5, by adjusting the convergence point, and after shooting to fit the cube, the cube is represented in 2D without a three-dimensional view, while the cylinder is a three-dimensional view as located in front of the cube Can be expressed.

As another example, referring to FIG. 6, when a photographing is performed after adjusting a convergence point to a cylinder, the cylinder is represented in 2D without a stereoscopic view, while the cube is stereoscopic as if it is positioned behind the cylinder. Can be expressed.

On the other hand, referring to Figure 7 (a), it is assumed that the cylinder is located behind the cube, and the cylinder is also located in front of the cube. At this time, when the convergence point is adjusted to the cylinder in front, as shown in Fig. 7 (b), the cylinder in front is represented in 2D, while the cube is three-dimensional and far from the cylinder in front The rear cylinder is represented as being farther than the cube while having a three-dimensional appearance.

On the other hand, the three-dimensional effect of the image varies depending on which subject the convergence point is aligned with. That is, as in the general photographing technique, by adjusting the composition of the photograph, the stereoscopic degree can be adjusted in the stereoscopic image by adjusting the conference point.

However, so far stereoscopic cameras have not been able to adjust this convergence point. Therefore, it is not easy for a general user to capture an image by adjusting the consumption point.

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

8 is an exemplary diagram illustrating a live view image displayed according to the process illustrated in FIG. 3.

As can be seen with reference to FIG. 8, a guide corresponding to a 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 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 cube that is closer than the convergence point may be displayed on the plane, and a second subject farther than the convergence point may be displayed by being hidden by the plane.

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

 When an operation signal for the convergence point is received from a user, the electronic device may adjust a convergence point between the plurality of optical lenses according to the manipulation input.

The electronic device may update and display the position of the guide on the live view image according to the adjustment of the convergence point.

For example, when the user moves the convergence point closer, in FIG. 8, the guide, that is, a plane having a predetermined transparency is displayed by moving in the + direction along the z axis. On the other hand, when the user moves the convergence point more remotely, the guide, that is, the plane having a predetermined transparency is displayed by moving in the − direction along the z axis.

As such, by providing the guide screen for the convergence point in the live view image, the user can more easily fit the convergence point to a desired subject and adjust the stereoscopic composition of the stereoscopic image as desired.

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

Referring to FIG. 9, first, an image acquired 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 processing the electrical signal.

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

The live view image may be the same as the screen displayed on the left side of FIG. In this case, referring to the left side of FIG. 10A, a plurality of subjects exist in the scene. In this case, as shown in the right side of FIG. 10A, the plurality of subjects are located at different distances. As described above, when the plurality of subjects are located at different distances, if the convergence point is not appropriately adjusted, the arbitrary subjects may be displayed with too much stereoscopic feeling. That is, the subject located too forward from the reference line of the convergence point may be expressed to have a very large three-dimensional effect. However, a general user may not know how much three-dimensional image should be taken without particular knowledge and experience.

Accordingly, a guide indicating whether one or more subjects are positioned in front of or behind the image is displayed on the image for the live view based on a convergence point between the plurality of optical lenses (S230). As such, a guide is provided to indicate 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. 10B, the electronic device 100 may measure a distance from 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 calculates disparity from images acquired through the plurality of cameras without the aid of the distance measuring sensor, and uses the disparity to communicate with each subject. Find distance.

As illustrated in FIG. 10B, the electronic device 100 may live a guide screen indicating whether one or more subjects are located at the front or the rear, based on a convergence point between the plurality of optical lenses. It can be displayed together with the view image.

The guide screen may be displayed as a point of view looking down from the sky, eg, a bird view point of view.

As shown in the right side of FIG. 10 (b), the guide screen includes a first line representing the convergence point (ie, a convergence point reference line), and a second line representing a front threshold point based on the convergence point (ie, a front limit line). It may include a third line (ie, a rear limit line) indicating a rear limit point based on the convergence point.

In this case, 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 there are a plurality of subjects in the scene, the electronic device 100 may calculate a distance between each subject and automatically adjust the convergence point so that the main subject and the auxiliary subject are expressed in an appropriate three-dimensional sense. This automatic adjustment function can be made automatically when any subject is located at a greater distance than the aforementioned rear limit line or front limit line. Alternatively, this automatic adjustment function may be performed so that the main subject is expressed in a constant three-dimensional sense.

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 unit for manipulation of the convergence point or display a button for manipulation of the convergence point on the display unit. Alternatively, the adjustment of the convergence point can be made by touching and dragging the convergence point reference line. Alternatively, the convergence point may be adjusted by touching and dragging the front limit line or the rear limit line. Alternatively, the adjustment of the convergence point may be made by touching the subject in the screen.

If the user receives an operation input for the guide, the electronic device may move and display the subject in front of or behind the convergence point according to the operation input.

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 the software implementation, the procedures and functions described herein may be implemented as 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.
