As shown in FIG. 2, the sliding state and the zoom level of each stage of the slide moving in multiple stages are correspondingly matched with each other. Here, the initial state 21 refers to a sliding-down state of the wireless communication terminal normally, and is a state in which a zoom level is not set (it is a 1x zoom state). Therefore, when the camera enters the camera mode in the initial state 21 and captures the image of the subject, the acquired image of the subject is not an enlarged or reduced image.

When the slide is moved from the initial state 21 to the first step 22, that is, when the slide is pushed up one step, the first step 22 is matched with the 2x zoom and thus the slide of the slide The image obtained when the sliding state is the first step 22 is an image enlarged by 2x zoom.

In addition, when the slide is moved from the first step 22 to the second step 23, the second step 23 is matched with the 4 times zoom and thus the image enlarged by the 4 times zoom is obtained. When the slide is moved one step further from the second step 23 to the third step 24, the third step 24 is matched with the 8 times zoom, so the image enlarged by the 8 times zoom is displayed. Obtained.

That is, since the sliding state and the zoom level of the slides are correspondingly matched with each other, the slides are slideed up in multiple stages such as the first stage, the second stage, and the third stage in the usual slide-down state (initial state). Accordingly, the zoom is automatically set to the corresponding zoom level so that an image having a desired magnification can be obtained.

The image acquisition unit (camera) 35 is controlled to operate from the table by searching from the table. That is, the control unit 37 activates the image acquisition unit (camera) 35 in response to receiving the camera mode entry request signal from the input unit (keypad) 33, and the zoom level setting unit as the slide is moved in multiple stages. The zoom level setting signal output from the 36 is received and the zoom level corresponding to the received zoom level setting signal is retrieved from the zoom level table, and the image acquisition unit (camera) 35 is operated according to the result. . For example, when the zoom level setting signal is received from the zoom level setting unit 36 as the sliding state of the slide is moved to the second step 23, the corresponding zoom level is stored in the storage unit 32. By searching from the level table, the image acquisition unit (camera) 35 controls the image acquisition unit (camera) 35 to acquire the image of the subject at the corresponding zoom level, that is, 4x zoom.

In the storage unit 32, an operation program and a system program of the control unit 37 are stored, and the operation program and system program are stored in a normal ROM area and can be erased as necessary. The storage unit 32 also includes a RAM for temporarily storing data generated during execution of various operation programs.

The storage unit 32 also stores a zoom level table in which the zoom level setting signal and the zoom level corresponding to each sliding state of the slide are matched with each other. For example, when the sliding state of the slide is the first step 22, the zoom level signal output by the zoom level setting unit 36 and the 2x zoom correspond to each other, and the sliding state is the second step. In the case of 23, the zoom level signal output from the zoom level setting unit 36 and the 4x zoom may be matched with each other. In this example, the magnification such as 2x zoom and 4x zoom is taken as an example, but the image of the subject is enlarged or enlarged according to the zoom magnification (ie, zoom level) stored in the zoom level table so as to correspond to each zoom level setting signal. It is obvious that it can be reduced.

The input unit 33 is composed of a plurality of numeric keys (letter keys), menu keys, and function keys for performing various functions, and outputs key data to the control unit 37 by an external operation. In addition, the input unit 33 is used to receive a camera mode entry request signal from a user. In this case, when the zoom level setting function using the slide is implemented as a selection of a specific menu provided by the terminal, the related key may be further received.
