Description

Personal broadcasting and shooting device {Personal broadcasting and shooting device}

The present invention relates to a personal broadcasting and photographing apparatus, and to an apparatus capable of simultaneously broadcasting and photographing by an individual in one structure. More specifically, it is a filming device that allows a broadcaster to simultaneously shoot a broadcaster's video while watching broadcast data. In particular, the video display can be detached and used without any extra means or modification to invert the video. It relates to a personal broadcasting and shooting device that can simultaneously increase the sharpness of an image by more than twice while simultaneously aligning the center of the image.

By providing video conferencing solutions to personal broadcasting platforms, the need for video activities using cameras such as personal broadcasting and video conferencing is increasing.

In particular, as telecommuting is increasing, business counseling through video and remote video education for professors and instructors is expanding.

However, one of the conventional lecturer's image or the image of the material provided by the image monitor is provided in different vertical, left, and right directions.

Therefore, the use of a separate electronic inversion device lowers the image quality, complicates the structure, and doubles the cost.

In addition, due to the pandemic, the need for personal broadcasting and filming devices is increasing, such as personal broadcasters, video conferencing through telecommuting, and lectures by university professors or lecturers through distance education.

However, in the current broadcasting station broadcasted by the announcer, the gaze of viewing the broadcast video data and the gaze of the announcer coincide with the viewer. Text or video, which is broadcast data, is turned up, down, left, or right in one direction. Therefore, a separate image reversing device is required.

In addition, since the broadcast camera itself has a structure combined with a prompt, the price is very high and it is not a structure that can be easily used by the general public.

In such a remote lecture, the top, bottom, left, and right images of the material the lecturer sees and the top, bottom, left, and right images of the lecturer taken with the camera must be the same.

Conventional Korean Utility Model Application No. 20-2000-0028928 ″Prompter Device″ opens the image monitor structure composed of TFT LCD PANNEL and disassembles the panel, then reverses the front and back of these panels to use the light source on the front display surface. It is modified to face it and used.

In other words, the transparent display panel is turned over and the transmission direction is reversed to change the top, bottom, left, and right of the image. This method is limited to a video display composed of a special separate transparent display panel and must have a structure that can be opened, so it is impossible to apply to a video display that cannot be opened by the general public, such as a laptop computer or tablet PC.

In addition, the Republic of Korea Application No. 10-1997-0067628 subject photographing apparatus for video conversation has a structure that allows both interlocutors to have a video conversation while looking at the face of the other party using a computer.

However, this structure is a structure in which a protective film is provided at the front end of the CRT monitor, a half-mirror is overlapped with a line inside the protective film, and a camera is provided on the top of the CRT monitor.

As such, the image splitter provided horizontally in a limited protective film with a thin front and rear can transmit and reflect the incident image and refract it upward. none.

Therefore, it is not possible to invert the top and bottom of the incident image. That is, since the image partially divided and reflected upwardly inside the protective film is incident as an image inverted from the second mirror to the camera, a separate image reversing device must be devised in the camera.

Therefore, in the existing imaging devices, one of the top, bottom, or left and right of the image compared to the image of the monitor is changed.

Therefore, there are converters that convert electrical signals or software that automatically converts the top and bottom of the image, but its use is extremely limited in response to various programs of image display.

In addition, since the image splitting mirror has a structure that partially transmits and partially reflects, the contrast is greatly reduced by 1/2 or less.

In addition, the sharpness of the image is deteriorated due to the characteristics of the image splitter that transmits and reflects only part of it.

Also, in the existing devices, the gaze of the broadcaster who sees the broadcast data on the screen and the gaze of the camera do not match. Therefore, the gaze of the broadcaster who sees and broadcasts the broadcast material does not coincide with the gaze of the viewer who watches it.

Therefore, there is a need for a personal broadcasting and filming device that allows the general public to simply give lectures or broadcasts anywhere without a separate reversing device using their laptop or tablet PC.

A camera having a shooting direction in a horizontal direction to the reflecting mirror rear reflection direction;

Image display mounting means formed in the rear and the lower portion of the image splitter;

It relates to a personal broadcasting and photographing combined device comprising a height adjusting means for adjusting the overall height of the case in the lower part of the case.

The terminology used herein is for the purpose of specifically describing specific embodiments. Hereinafter, advantages and features of preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 (a) is a schematic perspective view of one embodiment of the present invention, and Fig. 1 (b) is a cross-sectional configuration view of such a perspective view.

In the present invention, the configuration position and arrangement of each optical component are also important components. That is, if the arrangement is different, the action and effect will be different.

Case (1) constituting all the components of the present invention at an optical angle, the configuration of this case (1) is configured in a form in which the front and rear are opened in the horizontal direction, and the front open portion (1a) on the front of the case (1) is formed and the case (1) is composed of a mounting part (4) capable of mounting the image display (100) on the rear side.

That is, in the present invention as described above, the front opening part 1a is configured on the front side of the case 1, and the rear side is opened, but the mounting part 4 for mounting the image display on which the image display 100 is mounted is configured on the back side.

The image splitting mirror 2 provided at a 45° angle inside the case 1 has a reflective material deposited on its surface, so that the image incident on the 45° inclined surface is configured to reflect the entire image as a single image at a 90° right angle. A reflective surface 2a is formed, and at a 45 degree angle, it is composed of a transmission surface 2b that allows straight transmission in a straight direction.

The reason why the image splitter 2 should be configured as a 45° square is because one of the top and bottom images, left, right, or top and bottom of the broadcaster incident on the camera mounting unit 4 can be optically reversed. to be.

The reflectance of the reflective surface 2a of the image splitter 2 is composed of 20% or more and less than 80%, and the transmittance is provided in proportion to 80% or more and less than 20%.

The image splitting mirror 2 is configured to reflect the amount of light from the inclined surface by 20% or more and less than 80% in a right angle upward (or downward) and transmit it in a straight direction by less than 80% and 20% or more. In other words, by dividing the amount of light in the image, the right angle reflection and the straight transmission function of the entire image are performed at the same time.

As shown in Fig. 2(a), a reflector 3 is provided at a rear angle of 45° to refract the reflection direction at a right angle to the reflection direction reflected at a right angle of 90° from the image splitter 2 again.

The reflector 3 may be replaced with a right-angle prism 3a that reflects incident light at a right angle of 90°. The right angle prism has a high reflectance compared to the reflector (3) and has good durability. A camera mounting part 4 is provided behind the reflecting mirror 3 . A camera may be fixedly attached to the camera mounting unit 4 .

A black matte surface 2c is formed on one or both sides of the inner lower surface or upper surface of the case 1 . Such a black matte surface blocks external light incident through the image splitter 2 as shown in FIG. 1B and reflects a black shadow on the surface of the image display 100 to increase the contrast of the image.

That is, the matte black surface 2c is reflected from the image splitter 2 to act as a black matte on the surface of the image display 100, thereby blocking external light and increasing the contrast of the image by about two times or more.

However, such a matte black surface 2c has an area equal to or larger than that of the image display 100, and the image dividing mirror 2 is essentially provided with a 45° square, so that the matte black surface 2c is provided. ) is reflected at right angles. This is because, if this is not the case, the matte black surface 2c does not act on the entire area of the image display 100 , so that the sharpness of the image display 100 becomes non-uniform.

As shown in Fig. 1 (b), the mounting means 5 is formed on the rear of the case 1, that is, the rear of the image splitter 2, and the image display 100 such as a notebook computer, tablet PC, or image monitor is mounted and separated. make it

Case (1) on one side is provided with a height adjustment means (6) for raising and lowering the overall height of the case (1) to match the eye level of the broadcaster (7) is coupled with the main body (200).

This height adjustment means makes the center of the screen of the video display and the height of the broadcaster's gaze match, and at the same time, the position of the camera.

As an example of one embodiment, as shown in FIG. 3, a hinge 12 at the rear end of the upper plate 11 having a reflector 3 that reflects at right angles from the upper to the rear in the upper middle of the case 1 and the camera mounting unit 4 at the rear end thereof. ) and linked with the frame (not shown) including the image splitter (2).

As shown in Fig. 3, hinges 12 and 13 are provided on the lower front and upper rear of the image dividing mirror 2, respectively, and a hinge 13a is provided on the rear end of the mounting means 5, and is connected to the upper support 61 and the lower part It is configured in conjunction with the support 62 and the hinge 15 .

In addition, both sides of the upper plate 11 of the case 1 are provided with a left support plate (not shown) and a right support plate (not shown).

In this embodiment, as shown in FIG. 3, the upper plate 11, the image dividing mirror 2, the left support plate (not shown) and the right support plate (not shown) are folded, respectively, and the upper and lower supports ( 61, 62) and the height adjustment means (6) consisting of the pedestal (63) is folded and unfolded by each hinge (13, 14, 15) to adjust the overall height of the case (1).

Such a folding structure is an example of implementation. The height adjusting means 6 of the present invention is not limited thereto, and it is configured to be combined with the height adjusting means 6 of various methods such as a tripod support to adjust the height of the case 1, and can be folded or disassembled for storage and movement when carrying. will be.

In the present invention, as shown in Fig. 2 (a), the configuration positions of the image splitter 2, the image display 100, the reflector 3, and the camera mounting unit 4 are all configured on the same optical axis A.

The height is adjusted auxiliary to match the eye level of the broadcaster 7 and the optical axis A as shown in FIG. 2(b).

That is, in the present invention, as shown in (a) and (b) of FIG. 2, the eyes of the broadcaster 7, the center of the image display 100, and the center axis of the camera mounting unit 4 are all on one and the same optical axis (A). By configuring the broadcaster 7 will automatically coincide with the gaze by the shooting of the camera mounting unit 4 when looking at the central part of the image display 100 .

That is, even if the broadcaster 7 concentrates on the video screen provided on the video display 100 , the announcer's gaze is always directed toward the viewer on the TV news screen or advertisement screen.

In this case (1) configuration, the same effect can be obtained even if the entire structure and its components are arranged and configured in reverse order of top and bottom.

Accordingly, the face of the broadcaster 7 is reflected upward by the image splitter 2 and the broadcaster ( The face of 7) is reflected back at right angles by the reflector 3 again and is incident on the camera of the camera mounting unit 4 .

The data image provided from the video display 100 located at the rear end of the video splitter 2 is provided to the broadcaster 7 by passing through the video splitter 2 in a straight line.

Therefore, as shown in (a) and (b) of FIG. 2 , the broadcast image of the broadcaster 7 is reflected upward by the image splitter 2 and then reflected back by the reflector 3 and then transferred to the camera mounting unit 4 . Since it is incident, the top, bottom, left, and right of the image of the image display 100 and the image captured by the camera mounting unit 4 are the same.

That is, since the gaze of the broadcaster 7 who sees the video data and the gaze of the broadcaster 7 photographed with the camera mounting unit 4 automatically coincide with each other as shown in FIG. 2(b), the broadcaster ( 7)'s gaze always makes eye contact with the viewer.

Even if the reflection angle of the image splitter 2 and the configuration sequence of the reflection mirror 3 and the camera mounting unit 4 are configured in the reverse order, the same operation will be performed.

In this configuration of the present invention, as shown in Fig. 2 (a), the broadcaster 7 uses a separate keyboard (not shown) and a mouse (not shown) while watching the image 101 provided by passing through the image splitter 2 in a straight line. It can be connected to a laptop for lectures or video conversations.

This configuration of the present invention combines the main body 200 in a desktop form on a desk 300 provided with a chair 17 as shown in FIG. It can be used in combination with the height adjustment means (6).

In addition, the case (1) can be fixed on the desk (300) according to the standard sitting height of a person to some extent and adjusted to the height of the chair (17).

The purpose of the height adjusting means 6 described in the present invention is to match the eye level of the broadcaster 7, and the eye position and the case ( Various methods of adjusting the height may be applied so that the center position of 1) and the positions of the camera mounting unit 4 and the image 101 are the same optical axis A.

Therefore, as shown in (a) of Figure 2, the image of the image splitter 2, the image display 100, the reflector 3, the camera mounting unit 4 and the eyes of the broadcaster 7 are all the same optical axis (A) The present invention, characterized in that it is configured on a line, as shown in FIG. 2 (b), the eye height of the broadcaster 7 and the optical axis (A) of the image display 100 and the optical axis (A) of the camera mounting unit (4) Since it brings a matching effect, the broadcaster 7 automatically sees and broadcasts the camera mounting unit 4 even when broadcasting while watching only the video data, so the broadcaster 7's gaze of the broadcast being broadcast occurs at the same time It will match the viewer's point of view.

In addition, as shown in (b) of FIG. 4 , the image of the image display 100 that presents data without a separate additional image reversing device and the image captured by the camera mounting unit 4 are provided so that the top and bottom, left and right are consistent.

In addition, the black matte effect irradiated to the image display 100 at a right angle from the lower reflective surface provides the image display 100 with more than twice the sharpness.
