203: drive circuit 204: direction key detector

The present invention relates to a camera control apparatus and method for a camera-type mobile communication terminal, and more particularly, to mount a driving motor in a camera module in hardware, and to control the driving motor in software, thereby rotating the camera module in a direction desired by a user. The present invention relates to a camera control apparatus and a method of a camera-type mobile communication terminal, which allows a user to take a picture or to rotate a camera module automatically at the same time as selecting a shooting mode.

Recently released camera-type terminal is built-in (Built-in) type fixedly attached to the back of the main body of the terminal or the upper surface of the folder, or attached to the hinge portion, such as a folding type terminal configured to rotate 180 degrees It is attached to the end of the terminal, such as a slide type terminal is configured to rotate 180 degrees.

However, the terminal with the fixed camera as described above has a disadvantage in that the self-portrait mode can not be photographed, the terminal equipped with the 180-degree rotating camera module has the advantage that can be taken in the self-portrait mode compared to the fixed, but every time (mode There is a problem in that the camera module must be manually rotated in a desired direction every time the switch is made.

That is, the rotatable camera module can easily rotate by digging the groove 101 at the end thereof, as shown in FIG. 1, but in fact, since the protruding portion is too small for the user's hand, There is a problem that is difficult and cumbersome to rotate.

Therefore, the present invention was created to solve the above-mentioned conventional problems, and is equipped with a drive motor to the camera module in hardware, and control the drive motor in software, to rotate the camera module in the direction desired by the user It is an object of the present invention to provide a camera control apparatus and method of a camera-type mobile communication terminal that can be easily taken by taking a picture, or by automatically rotating the camera module at the same time as the shooting mode selection.

In order to achieve the above object, the present invention provides a rotatable camera module, a drive motor for automatically rotating in combination with the camera module, a drive circuit for driving the drive motor by forward / reverse rotation control, and a terminal. And a direction key detection unit for detecting a driving direction input through the navigation key of the control unit and controlling the driving circuit.

In addition, the present invention provides a method of detecting a direction key input when a camera photographing mode is selected by a menu operation of a terminal; And rotating the driving motor in a direction (forward direction, reverse direction) corresponding to the detected direction key to rotate the camera module coupled thereto in a desired direction.

According to the present invention, a small driving motor is mounted on the camera module, and a motor driving circuit for controlling the driving motor is additionally mounted, and then the driving motor is controlled by software by a navigation key or a camera photographing mode input by a user. Accordingly, an object of the present invention is to provide an apparatus and a method for rotating a camera module in a desired photographing direction so as to photograph.

Here, the camera shooting mode is 'outdoor shooting mode' or 'self-portrait shooting mode', and if the shooting mode is set in the menu setting step, the user may automatically rotate the camera module in a predetermined direction even if the camera is not rotated separately. In addition, the user's convenience is enhanced by allowing the user to perform camera shooting immediately.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, in adding reference numerals to the components of each drawing, it should be noted that the same components have the same reference numerals as much as possible even if displayed on different drawings.

Also, in the following description, numerous specific details, such as specific processing flows, are set forth in order to provide a more general understanding of the invention, and it is to be understood that the invention may be practiced without these specific details. It will be obvious to them.

In addition, detailed description of well-known functions and structures which are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

Figure 2 is a block diagram showing the configuration of the camera control device of the camera-type mobile communication terminal according to the present invention, in the case of the conventional rotational camera terminal was inconvenient by manual operation when adjusting the direction of the camera module, the present invention In the automatic control of the camera module by only navigation key operation or shooting mode setting, the camera module can be easily controlled by using only one hand.

Referring to FIG. 2, a rotatable camera module 201, a driving motor 202 for automatically rotating in combination with the camera module, and a driving circuit 203 for driving the driving motor by forward / reverse rotation control And a direction key detector 204 for detecting a direction input through a navigation key of the terminal to control the driving circuit.

Referring to FIG. 2, the direction key detecting unit 204 detects a navigation key operation on the upper or side surface of the terminal to rotate the driving motor in the upward direction (forward direction) or the downward direction (reverse direction). Outputs a control signal to rotate.

The drive circuit 203 receiving the control signal outputs a forward drive signal or a reverse drive signal to the drive motor in accordance with the control signal.

Accordingly, the drive motor 202 is rotated in the forward or reverse direction by the drive signal applied from the drive circuit, and also rotates the camera module coupled to the motor, thereby automatically toward the front or rear of the terminal Facing the camera to facilitate shooting.

3 is a flowchart illustrating a camera control method of a camera-type mobile communication terminal according to the present invention. When the user selects a camera shooting mode by operating a menu of the terminal, a navigation key input is detected to detect a corresponding direction (forward and reverse directions). Rotate the drive motor. In addition, when the detailed shooting mode (self-portrait mode, landscape mode, sticker photo mode, etc.) is selected after the camera shooting mode is selected, the direction of the current camera module is rotated in a direction suitable for the shooting mode.

For example, when the shooting mode is set to the self-portrait mode while the direction of the current camera module is toward the front of the terminal, the direction of the camera module does not operate the driving motor so that the camera module can maintain the current direction. When the shooting mode is set to the self-portrait mode while facing the camera, drive the motor so that the camera module faces the front.

On the contrary, when the shooting mode is set to landscape mode (normal picture mode) while the direction of the current camera module is toward the rear of the terminal, the direction of the camera module is not operated without operating the driving motor so that the camera module can maintain the current direction. If the shooting mode is set to landscape mode while facing the front of the terminal, the driving motor is operated so that the camera module faces the rear.

As described above, the present invention controls the rotation direction of the camera module by directly operating the navigation key in the general picture mode, or automatically rotates in the direction suitable for the shooting mode.

As described above, the apparatus and method for controlling a camera of the camera-type mobile communication device of the present invention includes a driving motor mounted in a camera module in hardware, and controlling the driving motor in software to rotate the camera module in a direction desired by a user. By taking a picture or by selecting a shooting mode, the camera module can be automatically rotated to easily take a picture.
