2 is a functional block diagram showing a configuration of a mobile communication terminal incorporating a digital camera according to an embodiment of the present invention, the mobile communication terminal incorporating a digital camera according to an embodiment of the present invention is an RF unit (1) ), LCD (3), keypad (4), memory (5), CODEC (6), audio (7), CCD lens (10), analog-to-digital converter (20), first interface (30) , The MSM 40, the second interface 50, and the recording memory 60.

The RF unit 1 RF modulates a signal received through an antenna, adjusts the signal to an appropriate level, and outputs the signal to the MSM 40.

In addition, the LCD 3 receives a display control signal from the MSM 40 and displays the same to a user.

On the other hand, the keypad 4 is composed of a number button, a symbol button and other function buttons are used to input the necessary information to the communication terminal serves to exchange signals with the MSM (40).
