Device and method for displaying an image according to a peripheral luminous intensity

A method for displaying an image in a mobile communication terminal with a camera and a sensor for sensing a peripheral luminous intensity, comprising the steps of:

• displaying an image signal received from the camera in an image capture mode;
• checking an output of the sensor in the image capture mode;
• and
• generating a second sensitivity control signal for prolonging an integration time of the image signal of the camera if the peripheral luminous intensity is smaller than a predetermined luminous intensity as a result of the checking, generating a first sensitivity control signal in a normal mode if the peripheral luminous intensity is not smaller than a predetermined luminous intensity as a result of the checking, and applying the sensitivity control signal to the camera.

A method for displaying an image in a mobile communication terminal with a camera and a sensor for sensing a peripheral luminous intensity, comprising the steps of:

• displaying an image signal received from the camera in an image capture mode;
• determining a kind of a sensitivity control mode in the image capture mode;
• generating a second sensitivity control signal for prolonging an integration time of the image signal of the camera if the sensitivity control mode is a manual mode as a result of the determination, generating a first sensitivity control signal in a normal mode if the sensitivity control mode is not the manual mode as a result of the determination, and applying the sensitivity control signal to the camera;
• and
• checking an output of the sensor if the sensitivity control mode is an automatic mode, generating the second sensitivity control signal for prolonging an integration time of the image signal of the camera if the peripheral luminous intensity is smaller than a predetermined luminous intensity as a result of the checking, generating the first sensitivity control signal in the normal mode if the peripheral luminous intensity is not smaller than a predetermined luminous intensity as a result of the checking, and applying the sensitivity control signal to the camera.

A device for displaying an image in a mobile communication terminal, comprising:

• a keypad having keys for setting an image capture mode and a sensitivity change mode;
• a sensor for sensing a peripheral luminous intensity;
• a controller for generating an image capture control signal when the image capture mode key is inputted, checking an output of the sensor in the image capture mode, generating a second sensitivity control command for prolonging an integration time of the image signal of the camera if the peripheral luminous intensity is smaller than a predetermined luminous intensity as a result of the checking, and generating a first sensitivity control command in a normal mode if the peripheral luminous intensity is not smaller than a predetermined luminous intensity as a result of the checking;
• a camera for capturing an image signal;
• a signal processor for processing the image signal outputted by the camera in a digital manner, generating a sensitivity control signal having an image integration time longer than in the normal mode when the sensitivity control command is inputted, and applying the sensitivity control signal to the camera to drive the signal processor when the image capture control signal is generated,;
• an image processor for compressing and processing the image signal outputted by the signal processor in units of frames to drive the image processor when the image capture control signal is generated,;
• and
• a display unit for displaying the processed image signal.
