Description

Position control device and method for portable imaging device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable photographing apparatus, and more particularly, to an apparatus for conveniently controlling a portable photographing apparatus such as a camcorder (CAMCORDER) for capturing and recording a scene desired by a user.

In general, a camcorder is a device that allows a user to record and record various scenes while moving freely. When a camcorder user shoots and records a performance or a meeting such as a play, a concert, or a music concert, the camcorder is often mounted on a tripod. In this case, the user checks the shooting status on the monitor while moving the shooting direction or inserts a zoom or a special shooting effect for various screen configurations so as not to be bored when watching the playback screen later. The photographing direction may be moved up, down, left and right by the user, and the zoom may be zoomed in or zoomed out. Special photographing effects to be inserted by the user include mosaic, art function, fade in or fade out, and other various digital effects.

When recording and recording such performances or gatherings, the user does not need to move the position with the camcorder. By doing so, the user himself could not watch the performance or the rally.

In order to solve this drawback, the patent application No. 6624 filed in 1996 by the applicant of the present application has an automatic photographing apparatus for automatically recording and recording by performing a function performing operation preset by the user's setting. It is starting.

However, since the automatic photographing apparatus disclosed in 662416 repeatedly performs only a predetermined function at a predetermined time, it may not only capture a desired scene at random, but also may capture an unnecessary scene. That is, the technique disclosed in No. 6624 has an advantage in capturing scenes in a static space, but has a disadvantage in capturing scenes in a dynamic space (eg, a baseball field).

Accordingly, it is an object of the present invention to provide a device and method that can be reserved in advance so as to accurately select a location when the portable photographing apparatus is fixed and photographed, and can also remotely or manually adjust the location.

Another object of the present invention is to provide an apparatus and method which can be reserved in advance so that the positioning and zooming functions can be accurately performed when the camcorder is fixed and photographed, and the position can be remotely or manually adjusted.

It is still another object of the present invention to provide an apparatus and method for conveniently controlling the position of a portable photographing apparatus without shaking the camcorder when photographing.

In addition, the status display unit 100 displays the operation mode state (mode setting and position setting key state) according to the present invention. In addition, the microcomputer 20 receives the current direction information from the motor driver 30 and records the processed information (direction information related to horizontal and vertical directions or zoom information) in the memory 60.

The motor 40 is operated according to the driving of the motor driver 30 and moves the fixed panel 50 coupled thereto. The motor driver 30 controls the motor 40 for implementing the present invention according to the processed contents. In addition, the position (horizontal and vertical) of the motor 40 is transmitted to the microcomputer 20. The fixed panel 50 is used to mount the portable imaging device. The memory 60 stores processing contents to be followed in accordance with the mode and its settings. The address is assigned to the map of the memory 60 according to the number of the positioning key 70. The remote control receiver 80 is controlled by the microcomputer 20 and receives a signal remotely controlled by the remote controller and transmits the signal to the microcomputer 20. The interface unit 90 performs zoom information interface between the microcomputer 20 and the portable photographing apparatus. The status display unit 100 is composed of, for example, LCD, LED, etc., and displays the operation state (mode setting and position setting key state) of the present invention under the control of the microcomputer 20.

FIG. 2 is a flowchart illustrating operations performed by the microcomputer 20 of FIG. 1 for position control of a portable photographing apparatus according to an exemplary embodiment of the present invention.

1 and 2, the operation according to the embodiment of the present invention will be described in detail. In the following description, an example of a portable photographing apparatus is applied to a camcorder.

The user mounts the camcorder on the fixed panel 50 of the position control apparatus of the present invention installed on a tripod. Thereafter, the user may select the direction input mode B or the zoom and direction input mode C by using the mode setting key 10 shown in FIG. 1. In the state where the direction input mode B or the zoom and direction input mode C is selected, the user sets the direction to be photographed and directs the camcorder there. This control is made possible by allowing the user to drive the motor 40 using the horizontal and vertical direction keys on the remote control or key panel.

If the user sets the mode setting key 10 to the direction input mode B and presses a predetermined number of the position setting key 70, the microcomputer 20 recognizes that the mode setting is the direction input mode B in step 108 of FIG. 2 and sets the position in step 109. Acknowledge the input of key 70. Thereafter, in step 110, the number of the positioning key is determined. Thereafter, in step 111, the position (horizontal and vertical state) of the motor 40 is received through the motor driver 30, and the direction input mode B currently set at the address in the memory 60 corresponding to the number of the current positioning key 70 and the processing contents according to the above setting ( That is, the current motor position). Thereafter, the microcomputer 20 displays the operation state of the mode setting and location setting key processed in step 116 through the status display unit 100.

Meanwhile, when the user sets the mode setting key 10 to the zoom and direction input mode C and presses a predetermined number of the position setting key 70, the microcomputer 20 sets the mode setting of the direction input mode B and the position setting key 70 in step 112 of FIG. 2. Recognize a predetermined input. Thereafter, in step 113, the number of the positioning key is determined. Thereafter, in step 114, the position (horizontal and vertical state) of the motor 40 is received through the motor driving unit 30, and the zoom and direction input mode C currently set at the address in the memory 60 corresponding to the number of the current positioning key 70 and processing according to the setting thereof are obtained. Record the content (ie the current motor position). Thereafter, the microcomputer 20 receives the zoom information of the portable photographing apparatus that enters through the interface 90 in step 115 and records the corresponding address set in the zoom and direction input mode C. Thereafter, the operation state of the mode setting and the position setting key processed in step 116 is displayed on the status display unit 100.

By performing steps 108 to 116 and steps 112 to 116, the user may reserve the position and the zoom of the object to be photographed by the user. With this reservation, even if the user presses only a predetermined number on the positioning key, the camcorder moves to the reserved object position (and operates in the reserved zoom state). This process is performed through steps 102 to 106 of FIG.

Specifically, when the user sets the mode setting key 10 to the normal mode A and presses a predetermined number reserved for the positioning key 70, the microcomputer 20 determines that the mode setting is normal mode A in step 101 of FIG. In step 102, the input of the positioning key 70 is recognized. Thereafter, in step 103, the number of the positioning key is determined. On the other hand, if the position setting key 70 is not input in step 102 and data is input from the remote controller receiving unit 80, the controller recognizes it in step 106 and determines the content of the data in step 107. The data authorized through the remote controller receiver 80 is key data corresponding to the number of the positioning key remotely controlled by the user. After determining the location key in step 103 or determining data applied through the remote controller receiver 80 in step 107, the microcomputer 20 selects the contents of the address corresponding to the key in step 104. Thereafter, in step 105, the direction of the motor 40 is adjusted based on the contents (for example, the corresponding mode + direction information, or the corresponding mode + direction information and zoom information) at the address. If the information on the address includes zoom information, it is transmitted to the portable photographing apparatus through the interface 90. Accordingly, the portable imaging device on the fixed panel 50 moves in the shooting direction reserved by the user and also zooms. After step 105, the microcomputer 20 proceeds to step 116 and displays the processed state of the mode setting and the position setting key through the status display unit 100.

This operation eliminates the fact that it was difficult for the camcorder to shake or to find the object immediately when the user tracked the object while holding the camcorder or photographing the camcorder while mounted on a tripod.

Examples of use according to embodiments of the invention are as follows. When the camcorder user wants to watch a baseball game, the controller installs a position control device on a triangular object and installs a camcorder, which is a portable photographing device, on the fixed panel 50 of the position control device. The user memorizes the pitcher's direction at ① of the positioning key 70 before starting the baseball game, and remembers the groove as ②, first base at ③, second base at ④, third base at ⑤ and so on. Let it be. Then, you can sit in the grandstand during a baseball game and shoot a pitcher, a catcher, a first base scene, etc. with just one key movement by remote control using a remote control. In the case of the camcorder having the interface 90 described with reference to FIG. 1, each zoom magnification may be selected and used in parallel.

In the description of the operation according to the embodiment of the present invention, it is described to select several keys for convenience, but the selection of these keys may also be realized by a mode shift method on an OSD (On Screen Display) or LCD (Liquid Crystal Dispaly) display panel. . In addition, in the present invention, the position control apparatus according to the embodiment of the present invention is described as a separate unit so that it can be applied to any portable photographing apparatus on the market (for example, a camcorder, a camera, etc.). It can also be realized by application.

As described above, it will be apparent to those skilled in the art that the present invention can be implemented with various changes and modifications without departing from the spirit of the present invention according to the specific embodiments described above. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the equivalent of claims and claims.

As described above, when the photographing direction is moved during the photographing of a portable device such as a camcorder, the present invention can be accurately moved at once in a desired direction without shaking. You can also adjust the zoom factor if you have an interface, such as a camcorder.
