Abstract

A device and method for displaying an image in a mobile communication terminal. A camera captures an object'"'"'s image and generates image data. A display data processor processes the image data generated by the camera on the basis of a display standard. An image codec compresses the image data processed by the display data processor and generates image data of at least one still picture in a still-picture capture mode. A thumbnail generator generates image data of at least one thumbnail picture of a set size from the image data processed by the display data processor in the still-picture capture mode. A user data generator generates user data according to a display mode. A display unit displays the image data on a first display area and displaying the user data on a second display area. A controller cuts off a path of the image data by controlling the display data processor in the still-picture capture mode, drives the image codec and the thumbnail generator such that the image data displayed on the first display area can be compressed, stores the image data compressed by the image codec as the still picture, and stores the image data generated by the thumbnail generator as the thumbnail picture.

Claims

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

a camera for capturing an object'"'"'s image and generating image data;

a display data processor for processing the image data generated by the camera on the basis of a display standard;

an image codec for compressing the image data processed by the display data processor and generating image data of at least one still picture in a still-picture capture mode;

a thumbnail generator for generating image data of at least one thumbnail picture of a set size from the image data processed by the display data processor in the still-picture capture mode;

a user data generator for generating user data according to a display mode;

a display unit for displaying the image data on a first display area and displaying the user data on a second display area; and

a controller for cutting off a path of the image data by controlling the display data processor in the still-picture capture mode, driving the image codec and the thumbnail generator such that the image data displayed on the first display area can be compressed, storing the image data compressed by the image codec as the still picture, and storing the image data generated by the thumbnail generator as the thumbnail picture.

2. The device as set forth in claim 1, wherein the display data processor comprises:

a scaler for scaling the image data output from the camera to a display size of the display unit.

3. The device as set forth in claim 2, wherein the image processor further comprises:

a color converter connected to an output terminal of the scaler for performing a color format conversion where the camera outputs image data based on a YUV format and the display unit displays image data based on an RGB format.

4. The device as set forth in claim 2, wherein the image processor further comprises:

a color converter connected to an input terminal of the scaler for performing a color format conversion where the camera outputs image data based on a YUV format and the display unit displays image data based on an RGB format.

5. The device as set forth in claim 1, wherein the user data generator generates first user data for indicating a release of the image capture mode, and second user data for indicating at least one of a remaining amount of a battery power of the mobile communication terminal, reception sensitivity, and time information in the image capture mode.

6. The device as set forth in claim 5, wherein the display unit comprises:

the first display area for displaying the image data; and

the second display area for displaying the second user data at an upper portion of the first display area, and displaying the first user data at a lower portion of the first display area.

7. A method for displaying an image in a mobile communication terminal, the mobile communication terminal including a camera for capturing an object'"'"'s image and generating image data, a user data generator for generating user data according to a display mode, and a display unit for displaying the image data on a first display area and displaying the user data on a second display area, the method comprising the steps of:

transmitting the image data generated by the camera and the user data generated by the user data generator to the first and second display areas of the display unit in an image capture mode, and displaying a moving picture; and

when a still-picture capture command is generated in the image capture mode, compressing and encoding the image data displayed on the first display area of the display unit, generating image data of at least one still picture and image data of at least one thumbnail picture of a set size, and storing the generated image data.

8. The method as set forth in claim 7, further comprising the step of:

when the still-picture capture command is generated, displaying at least one of the user data for registering a still-picture name, a name of a place in which the still picture is captured on the second display area, and registering a user'"'"'s input information along with the still picture.

9. A method for displaying an image in a mobile communication terminal, the mobile communication terminal including a user data generator for generating user data according to a display mode, and a display unit for displaying image data on a first display area and displaying the user data on a second display area, the method comprising the steps of:

transmitting received image data and the user data generated by the user data generator to the first and second display areas of the display unit in a communication mode, and displaying a moving picture; and

when a still-picture capture command is generated at a time of displaying the received image data, compressing and encoding the image data displayed on the first display area of the display unit, generating image data of at least one still picture and image data of at least one thumbnail picture of a set size, and storing the generated image data.

10. The method as set forth in claim 9, further comprising the step of:

when a second shift key is input in the thumbnail display mode, displaying the predetermined number of next thumbnail pictures stored in the image memory on the first display area; and

when a selection key is input in the thumbnail display mode, reading image data of a still picture corresponding to a selected thumbnail picture and displaying the image data of the still picture corresponding to the selected thumbnail picture on the first display area.

12. The method as set forth in claim 11, wherein the step of displaying the image data of the still picture corresponding to the selected thumbnail picture further comprises the step of:

displaying at least one of the user data including a still-picture name, a name of a place in which the still picture is captured on the second display area.

13. A method for displaying an image in a mobile communication terminal, the mobile communication terminal including a camera for capturing an object'"'"'s image and generating image data, a user data generator for generating user data according to a display mode, and a display unit for displaying the image data on a first display area and displaying the user data on a second display area, the method comprising the steps of:
