Structures for use have been proposed.

A mobile wireless terminal equipped with a camera compresses image data captured by a CCD (Charge Coupled Device) and records it in a flash memory, and the image data recorded in the flash memory is transferred to a personal computer (PC) and stored in a memory. The data is displayed on a monitor or transmitted using a wireless data communication network.

In order to capture an image with a mobile wireless terminal equipped with a camera as described above, the user should directly pick up the mobile wireless terminal to approach the subject and adjust the image so that the image is properly positioned on the screen.

However, there is a problem that it is not easy to adjust the focusing point according to the center of the screen while looking at the LCD (Liquid Crystal Display) screen of the subject photographed according to the shooting situation.

On the other hand, recently, a terminal capable of taking pictures while covering a case of a mobile communication terminal has been developed and commercialized. As an example, Korean Patent Laid-Open Publication No. 2002-0061346 proposes a camera direction indicating device for a mobile communication terminal that easily fits the center of a subject to be photographed at the center of the screen without going through the screen.

The structure is a camera lens 102 provided on the upper side of the display unit 101 of the folder type terminal 100 as shown in Figs. 1 and 2, or a camera lens provided on the flip type terminal main body 200 ( 201) The laser light emitting device 300 is provided at one side, and as shown in FIG. 3, when the subject is located in the viewer area of the camera lens 102 or 201, the position signal is transmitted through an image input unit. The control unit may be configured to control the direction indicating drive unit to adjust the laser light emitting device 300 to be positioned on the subject, thereby positioning the subject of the photographing subject in the center of the display unit of the terminal.

That is, during close-up photography, the center of the desired portion is indicated by the pointer of the laser light emitting device so that the portion can be photographed to the peripheral portion, but after inputting a key corresponding to the driving portion of the camera portion, the laser light emitting device is driven. When the pointer of the laser light emitting device is located at the center of the photographing object, the user is informed that the photographing object is the center of the display unit, and then photographing by pressing the shutter.

In the above method, the center point and the shooting can be set by specifying a certain point, which is effective only when the center point is taken in close-up photography, but only a part of the image is taken out of the possibility of taking out unnecessary surrounding background.

Accordingly, when shooting at a certain distance, it is difficult to know how much background is in the surroundings, and when the user is located behind the terminal while the case is covered, it is very difficult to accurately photograph only a desired part of the subject. It implies

Accordingly, the present invention has been proposed to solve the above problems, and the user terminal in the case covered with the case by generating a photographing guideline by irradiating four rectangular points according to the angle of the subject using a laser pointer It is an object of the present invention to provide a camera direction indicator for a mobile communication terminal using a laser pointer that can accurately photograph only a desired subject part even if located behind.
