The present invention relates to a method for performing multitasking of a portable terminal, and more particularly, to a method for performing multitasking of a portable terminal capable of simultaneously performing two tasks through two external display units.

When it is necessary to perform another task while performing one task in a general portable terminal, the user of the portable terminal must perform a task to be performed after finishing the current task.

For example, when watching a DMB or recording a video, when a call comes in or needs to send or receive a message, or when the data stored in the portable terminal needs to be retrieved, the user of the portable terminal ends recording of the currently viewed DMB or video. Only then can you make calls, send and receive messages, or retrieve data.

As described above, a user of a mobile terminal providing only one task execution at a time may be inconvenient to repeat the end of the task and perform the task every time the task is performed.

Accordingly, an object of the present invention is to provide a method for performing multitasking of a portable terminal capable of simultaneously performing two tasks through two external display units provided in the portable terminal.

A method of performing multitasking in a mobile terminal for achieving the above object includes the steps of: performing a first service mode on a first display of the mobile terminal; If a second service mode is selected while the first service mode is performed on the first display unit, the first display unit performs a first service mode, and the second display unit of the mobile terminal performs the second service mode. Characterized in that made.

DETAILED DESCRIPTION Hereinafter, detailed descriptions of preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the same components in the figures represent the same numerals wherever possible.

1 is a diagram illustrating a configuration of a portable terminal according to an embodiment of the present invention, which illustrates a configuration of a portable terminal including a camera.

Referring to FIG. 1, the RF unit 123 performs a wireless communication function of the portable terminal. The RF unit 123 includes an RF transmitter for upconverting and amplifying a frequency of a transmitted signal, and an RF receiver for low noise amplifying and downconverting a received signal. The modem 120 includes a transmitter for encoding and modulating the transmitted signal, a receiver for demodulating and decoding the received signal, and the like. The audio processor 125 may configure a codec, and the codec includes a data codec for processing packet data and an audio codec for processing an audio signal such as voice. The audio processor 125 converts and reproduces the digital audio signal received by the modem 120 through the audio codec or converts the analog audio signal generated from the microphone into a digital audio signal through the audio codec and converts the digital audio signal into the digital audio signal. Sends the function to 120. The codec may be provided separately or included in the controller 110.

The memory 130 may include program memory and data memories. The program memory may store programs for controlling a general operation of the portable terminal and programs for controlling multitasking of the portable terminal according to an embodiment of the present invention.

Herein, it is assumed that the camera sensor is a CCD sensor, and the signal processor may be implemented by a digital signal processor (DSP). In addition, the camera sensor and the signal processor may be integrally implemented or may be separately implemented.

The image processor 150 performs a function of generating screen data for displaying an image signal output from the camera unit 140. The image processor 150 processes the image signal output from the camera unit 40 in units of frames, and outputs the frame image data according to the characteristics and size of the display unit 160. In addition, the image processor 50 includes an image codec and performs a function of compressing the frame image data displayed on the display unit 160 in a set manner or restoring the compressed frame image data to the original frame image data. The image codec may be a JPEG codec, an MPEG4 codec, a wavelet codec, or the like. It is assumed that the image processor 150 has an On Screen Display (OSD) function, and may output on-screen display data according to a screen size displayed by the control of the controller 110.

The display unit 160 displays the image signal output from the image processor 50 on the screen, and displays the user data output from the controller 110. The display unit 160 may use an LCD. In this case, the display unit 160 may include an LCD controller, a memory capable of storing image data, and an LCD display device. In this case, when the LCD is implemented using a touch screen method, the LCD may operate as an input unit. In addition, the display unit 160 includes two external display units, the first display unit 161 and the second display unit 162, according to an exemplary embodiment.

The first display unit 161 and the second display unit 162 may be located outside so that the user can see them at the same time. In addition, the first display unit 161 may be displayed in the first service mode, and at the same time, the second display unit 162 may display the second service mode.

The key input unit 127 includes keys for inputting numeric and character information and function keys for setting various functions. In addition, the key input unit 127 may include a specific key for activating keys for performing the second service mode while performing the first service mode. In addition, the key input unit 127 may include a specific key for activating keys for performing the first service mode while performing the second service mode according to an embodiment of the present invention.
