Next, operation of autofocusing in the camera mode of the portable terminal having the configuration as shown in FIG. 1 will be described.

First, the camera unit 150 is a module including a built-in camera mounted on the portable terminal. The camera unit 150 may use a charge coupled device (CCD) sensor. The image captured by the camera unit 150 applies a control signal to the camera unit 150 through autofocusing so as to focus optimally under the control of the controller 190. Then, the camera unit 150 moves the lens by the control signal. Then, the subject is photographed with the optimum focus according to the movement of the lens.

Then, the signal processor 160 converts the image signal output from the camera unit 150 into digital image data and outputs it to the image processor 170. Thereafter, the display unit 180 displays the digital image data processed by the image processor 170.

In the above, the configuration of the mobile terminal according to an embodiment of the present invention has been described. Hereinafter, a method of photographing a portable terminal according to an exemplary embodiment of the present invention will be described.

First, the portable terminal according to an embodiment of the present disclosure provides various shooting modes when performing a camera function. The setting of the shooting mode will be described.

2 is a screen example for setting a shooting mode of a portable terminal according to an exemplary embodiment of the present invention.

In the camera mode, the controller 190 displays a lower menu list of the camera mode through the display unit 180. At this time, when the user selects the shooting mode setting menu, the controller 190 detects this and provides a shooting mode setting screen through the display unit.

An example of such a screen is shown in FIG. 2. As shown, the shooting mode setting screen displays the autofocusing mode, the normal mode, and the automatic switching mode, and allows the user to select through the corresponding radio button.

In the autofocusing mode, the portable terminal performs autofocusing. In the normal mode, the portable terminal does not perform autofocusing.

In the automatic switching mode according to an embodiment of the present invention, when the movement of the portable terminal operates at a predetermined sensitivity or more, the shooting mode is switched to or maintained in the auto focusing mode. In addition, when the movement of the portable terminal is less than the preset sensitivity, the shooting mode is switched to or maintained in the normal mode.

The setting of the shooting mode may be set before entering the shooting mode, or may be set by calling the shooting mode setting screen of FIG. 2 during the preview mode of the camera mode.

As described above, the automatic switching mode detects the movement of the portable terminal. Hereinafter, a method for setting the sensitivity of the movement will be described.

3 is an example of a screen for setting the sensitivity for detecting the degree of movement of the mobile terminal according to an embodiment of the present invention.

The motion detector 195 includes a motion sensor. Accordingly, the controller 190 measures the movement degree of the mobile terminal through the motion detection unit 195 at the time of shooting, and then resets the shooting mode (auto focusing mode and normal mode) according to the degree of the operation. In other words, if it detects a motion above the set sensitivity, it maintains or switches to the auto focusing mode.

At this time, if the motion detection sensitivity of the motion sensor is set too sensitively, the shooting mode is always performed in the auto focusing mode, and vice versa, the shooting in the normal mode is always performed.

That is, when the sensitivity of the motion sensor is too sensitive, the motion sensor may detect that the mobile terminal is moving when the user recognizes that the mobile terminal is stationary and stopped. In addition, when the sensitivity is not sensitive, the motion sensor may not detect a situation in which the mobile terminal is actually moving.

For this reason, in an embodiment of the present invention, it is possible to set the sensitivity of the operation degree detected by the motion sensor.

Referring to FIG. 3, the sensitivity range setting of the motion sensor according to an embodiment of the present disclosure provides a normalization range for the motion sensor to detect the motion of the mobile terminal.

That is, the user is selected by normalizing (for example, 1 to 10) to a range of values and providing the sensitivity of the motion. Here, the numbers 1 to 10 are relative values, not absolute values indicating the sensitivity of the operation. Therefore, by providing the user to reset according to the situation, it is possible to obtain a better picture quality.

Therefore, when the user selects any one of the normalized values through a key input and selects OK on the screen as shown in FIG. 3, the controller 190 detects this and reflects the selected values.

Hereinafter, a method of photographing a portable terminal according to an exemplary embodiment of the present invention in a state where sensitivity is set as described above will be described.

The present invention is to shorten the shooting time by detecting the movement of the portable terminal in the case of continuous shooting, if the portable terminal is moved again, if the portable terminal is not moved, omitting the focusing process.

That is, when the portable terminal moves above the set sensitivity, the auto mode is switched to the auto focusing mode if the shooting mode was the normal mode, and the auto focusing mode is maintained if the shooting mode is the auto focusing mode. When the portable terminal moves below the set sensitivity, the shooting mode is kept in the normal mode if the shooting mode was the normal mode, and the mode is switched to the normal mode if the shooting mode is the auto focusing mode. Then, if necessary, switch to the auto focusing mode or the normal mode, and change to the required mode for the next shooting.

Therefore, it is possible to solve the problem of taking a long shooting time by performing autofocusing continuously in the autofocusing mode. In addition, it is possible to automatically switch to the auto focusing mode to shoot in the shooting where auto focusing is required.

This method is effective in continuous shooting mode. The continuous shooting mode is a mode in which a subject is photographed continuously a predetermined number of times, and is mainly used when photographing a moving subject continuously.

Hereinafter, a recording method of a mobile terminal according to an embodiment of the present invention in the continuous shooting mode will be described. 4 is a diagram illustrating a photographing method of a portable terminal according to an exemplary embodiment of the present invention, and FIG. 5 is a screen example illustrating a photographing method of a portable terminal according to an exemplary embodiment of the present invention. Here, it is assumed that the portable terminal is set to the continuous shooting mode.

Referring to FIG. 4, the controller 190 is performing the standby mode in step S401. If there is a key input for selecting a camera mode according to a user's selection during the standby mode, the controller 190 detects it in step S403 and displays a camera menu list in step S405. An example of such a screen is illustrated in FIG. 5. As shown, the menus "1. Shooting", "2. Album", "3. Shooting mode setting" and "4. Motion detection sensitivity setting" are displayed. In addition, various menus can be provided.

On the other hand, if the camera mode is not selected and another function is selected, the controller 190 detects this in step S405 and performs the corresponding function in step S407.

When the user selects the “1. Shooting” menu while displaying the camera menu list, the controller 190 detects this in step S409 and proceeds to step S411. On the other hand, if a menu other than the shooting menu is selected, the process proceeds to step S413 to perform the corresponding function. At this time, if the "2. Album" menu is selected, the album function to display a list of the pre-recorded picture is performed. In addition, if the menu item "3. Set shooting mode" and "4. Set the motion detection sensitivity" is selected, as described above with reference to FIGS. 2 and 3, the shooting mode setting or the motion detection sensitivity setting may be performed.

In step S411, the controller 190 performs a preview mode. In the preview mode, the controller 190 displays an image captured by the camera unit 150 on the display unit. In the preview mode, the user checks the shape of the subject through the display unit 180 and measures the composition.

In this case, when the user selects the photographing key in a state of facing the lens of the camera unit 150, the controller 190 detects it in step S413 and performs autofocusing in step S415. When autofocusing is completed, the controller 190 captures a subject through the camera unit 150 in step S417.

Autofocusing is a process of automatically focusing a subject displayed on the display unit in the preview mode. In other words, autofocusing is a process of automatically focusing by moving a lens back and forth by measuring a distance between a focusing point, which is a subject, and a lens. Therefore, if the user moves the portable terminal or the subject moves, autofocusing in step S415 is repeatedly performed.

In this case, when the photographing key is a half shutter, when the half shutter input is sensed, the controller 190 performs autofocusing. When autofocusing is completed, the autofocusing method is provided in a way that a user can recognize that autofocusing is completed. For example, a lamp, a vibration, a sound, and a method of displaying on the display unit 180 can be used. Then, the user can recognize that autofocusing is completed and can photograph the subject by pressing the on shutter.

When shooting is completed, the controller 190 determines whether the number of shots is a preset number of shots in operation S419. As a result of the determination, if the number of shots is a preset number of shots, the controller 190 proceeds to step S427. If the number of shots is less than the preset number of shots, the controller 190 proceeds to step S421 to repeatedly perform a process according to a continuous shooting function. do.

In operation S421, the controller 190 detects an operation (movement) degree of the mobile terminal through the motion detector 195 to determine whether the movement of the mobile terminal is greater than or less than a preset sensitivity. As a result of the determination in step S421, if the movement of the portable terminal is equal to or greater than the preset sensitivity, the controller 190 maintains the shooting mode in the autofocusing mode in step S425. Then, the controller 190 proceeds to step S415 to take a picture of the subject according to the autofocusing mode shooting procedures S415 and S417. In operation S421, when the movement of the portable terminal is less than the preset sensitivity, the controller 190 switches the shooting mode to the normal mode in step S423. Then, the controller 190 proceeds to step S417 to shoot the subject according to the normal shooting mode shooting procedure (S417). For this reason, during continuous shooting, when there is no movement of the portable terminal, the camera can take a picture through the autofocusing process only once, so that the shooting time can be shortened by the autofocusing time.

As described above, the controller which has performed continuous shooting by the preset number of shootings performs the review mode in step S427. In the review mode, the controller 190 temporarily stores the captured image and displays it on the display unit 180.

In the review mode of the continuous shooting, as many shots as the shots can be displayed on the display unit 180 through a thumbnail. The user can then view the photographed picture and optionally save the picture.

In addition, in the review mode, the controller 190 preferably displays the photographing information applied at the time of photographing together with the photographed picture on the display unit 180. For example, it is preferable to display whether the flash is used and the brightness, the sensitivity to the light, the width of the aperture, the shutter speed, etc. together with the photographed picture. The user may check the picture on the display unit 180 and determine whether to save the picture or reset the sensitivity for motion detection according to the state.

If the user selects any one or more of the photographed pictures and selects a key to store the pictures, the controller 190 detects them in step S429, and stores the pictures in the storage 140 in step S431.

Next, in step S433, the controller 190 detects whether the user ends or continues shooting and proceeds to step S411. Otherwise, the controller 190 ends the camera mode.

As described above, according to the present exemplary embodiment, unnecessary autofocusing processes can be reduced by sensing the operation degree of the subject during continuous shooting and resetting the shooting mode according to the operation degree. Thus, the shooting time can be shortened.

As described above, in the detailed description of the present invention has been described with respect to specific embodiments, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below, but also by the equivalents of the claims.

As described above, according to the camera photographing method of the mobile terminal of the present invention proposed by the present invention, by detecting the degree of movement of the mobile terminal at the time of shooting, resetting the shooting mode according to the degree of movement to take continuous autofocusing process Can be reduced. Thus, the shooting time can be shortened. Therefore, there is an advantage of increasing the use of the mobile terminal.
