Abstract

A mobile communication terminal having a camera and a controlling method thereof are provided. The controlling method may include: determining an operating state of the mobile communication terminal; converting a mode of the camera, installed in the mobile communication terminal, to a particular mode among at least one photographing mode according to the determined operating state of the mobile communication terminal; extracting a data value that is photographed in the converted particular mode; and adjusting a brightness of a display screen of the mobile communication terminal using the extracted data value.

Claims

1. A method of controlling a mobile communication terminal having a camera, the method comprising:

determining an operating state of the mobile communication terminal;

converting a mode of the camera, installed in the mobile communication terminal, to a particular mode among at least one photographing mode according to the determined operating state of the mobile communication terminal;

extracting a data value that is photographed in the converted particular mode; and

adjusting a brightness of a display screen of the mobile communication terminal using the extracted data value.

2. The method of claim 1, wherein, when the determined operating state of the mobile communication terminal is in a standby state, the converting comprises converting the mode of the camera to a luminance measurement mode, and the extracting comprises extracting a measured luminance value.

3. The method of claim 1, wherein, when the determined operating state of the mobile communication terminal is in a general call state, the converting comprises converting the mode of the camera to a proximity detection mode, and the extracting comprises determining the proximity of a subject in the proximity detection mode.

4. The method of claim 3, wherein the determining the proximity of the subject in the proximity detection mode comprises determining the proximity of the subject based on an image photographed by the camera.

5. The method of claim 1, wherein the adjusting comprises adjusting a liquid crystal display (LCD) backlight of the mobile communication terminal to a particular step among at least one step.

6. The method of claim 1, further comprising:

converting the mode of the camera of the mobile communication terminal to an image sensor mode among the at least one photographing mode, when the determined operating state of the mobile communication terminal is in a video call state; and

controlling image data, photographed in the converted image sensor mode, to be transmitted to a correspondent mobile communication terminal.

7. The method of claim 1, further comprising:

converting the mode of the camera of the mobile communication terminal to a motion recognition mode among the at least one photographing mode, when the determined operating state of the mobile communication terminal is in a key input ready state;

detecting image data that is photographed in the converted motion recognition mode;

generating a particular camera signal corresponding to the detected image data; and

controlling the mobile communication terminal to operate according to the generated particular command signal.

8. A computer-readable recording medium storing a program for implementing the method of claim 1.

9. A mobile communication terminal having a camera, comprising.

a camera unit to photograph a still image or a motion picture;

a decision unit to determine an operating state of the mobile communication terminal;

a conversion unit to convert a mode of the camera, installed in the mobile communication terminal, to a particular mode among at least one photographing mode according to the determined operating state of the mobile communication terminal;

a proximity decision unit to determine the proximity of a subject in the converted particular mode; and

an adjustment unit to adjust a brightness of a display screen of the mobile communication terminal based on the decision result of the proximity decision unit.

10. The mobile communication terminal of claim 9, wherein, when the determined operating state of the mobile communication terminal is in a standby state, the conversion unit converts the mode of the camera to a luminance measurement mode, and the decision unit extracts a measured luminance value.

11. The mobile communication terminal of claim 9, wherein, when the determined operating state of the mobile communication terminal is in a general call state, the conversion unit converts the mode of the camera to a proximity detection mode, and the proximity decision unit determines the proximity of the subject based on processing of an image that is photographed by the camera in the proximity detection mode.

12. The mobile communication terminal of claim 9, wherein the camera unit, the decision unit, the conversion unit, the proximity decision unit, and the adjustment unit are connected to a system controller of the mobile communication terminal and a single communication line, and are constructed as a single chip module.
