In addition, the data processing method of the terminal of the present invention in order to achieve the above object, the data processing method applied to a terminal having a camera module and a display unit, comprising: selecting one of the basic mode or extended mode; When the basic mode is selected, processing image data having a resolution corresponding to a display window size of the display unit, and displaying the image data as screen data; And when the extended mode is selected, processing image data having a resolution according to a selective resolution, and displaying or storing the image data as screen data or storage data.

Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the technical idea of the present invention. .

2 is a block diagram illustrating a data processing apparatus of a terminal according to an embodiment of the present invention. The data processing apparatus of the terminal of the present invention includes a high pixel sensor 210, a signal processor 220, and an image processor 230. , A display unit 240, a controller 250, a key input unit 260, and a memory 270.

The high pixel sensor 210 acquires a high quality image and converts an optical signal of the obtained image into an electrical signal.

In addition, the signal processing unit 220 receives a control signal from the controller 250 to be described later, the mode is set according to the control signal, and the image input from the high pixel sensor 210 will be described later in the basic mode. It converts the image data of the resolution set according to the display window size of the display unit 240 and converts the image data of the selective resolution in the extended mode. The resolution set according to the display window size may be 128 × 160, and the selective resolution may be 1024 × 768, but is not limited thereto.

The image processor 230 receives the image data from the signal processor 220 and generates screen data or stored data.

In addition, the display unit 240 serves to receive and display screen data from the image processor 230.

The controller 250 generates a control signal for selecting one of the basic mode and the extended mode, and performs a general operation of the terminal. Here, in the generation of the control signal, the default mode is set as a default value, and the movement of the image input from the high pixel sensor 210 is reduced by focusing on the fact that there is almost no movement of the terminal immediately before the user takes a picture. If there are few, you can switch to extended mode.

In addition, the key input unit 260 includes keys for inputting numeric and character information and function keys for setting various functions. When the user executes a key input, the key input unit 260 generates a selection signal and outputs it to the controller 150.

First, when the user activates the camera module of the terminal, the signal processor 220 processes the image input from the high pixel sensor 210 into image data having a resolution corresponding to the size of the display window of the display unit 240.

Then, when the user almost moves the terminal to take a picture, the controller 250 detects this and switches the signal processor 220 to the extended mode.

At this time, the mode switching condition is according to the following equation.

Here, T is a constant having a value between 0 and 1, and may be set according to an environment, and S is equal to each other by comparing one image input from the high pixel sensor 210 with another image input after a predetermined time. The image change value obtained by comparing the pixel set of the position. In addition, when the x value obtained through Equation 1 exceeds a predetermined threshold value, the basic mode is switched to the extended mode.

In addition, the case in which the user inputs an image capture signal through the key input unit 260 may be used as a mode switching condition from the basic mode to the extended mode, but is not limited thereto.

The condition of switching from the extended mode to the basic mode may be a case in which the capture is not performed for a predetermined time or a case in which the x value according to Equation 1 falls below the threshold, but is not limited thereto.
