Embodiment Construction

[0029] The present invention will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0030] Figure 4 An apparatus for processing JPEG data in a mobile communication terminal according to an embodiment of the present invention is described.

[0031] In this embodiment, the apparatus for processing JPEG data in a mobile communication terminal includes a command input unit 10, a control unit 20, an image data storage unit 30, a decoding unit 40, and a display unit 50, such as Figure 4 shown.

[0032]When an image is downloaded from an external device through a data cable or an image stored in an SD card is downloaded to a mobile communication terminal, a JPEG file corresponding to the downloaded image is stored in the image data storage unit 30 by the control unit 20 . When a JPEG file is downloaded through the wireless Internet, the JPEG ...

Abstract

Provided is a device for resizing a JPEG image having a nonstandard size at a predetermined ratio to output the resized image on a display unit without distortion in a mobile communication terminal. A method for processing a JPEG image in a mobile communication terminal comprises extracting image sizes (X, Y) from JPEG data of a JPEG file stored in an image data storing unit, comparing display area sizes (dx, dy) of the display unit with the image sizes (X, Y), and resizing the image sizes (X, Y) while maintaining the ratio of width:length in consideration of the display area sizes (dx, dy) to output the resized image to the display unit.

Description

technical field [0001] The present invention generally relates to an apparatus and method for processing JPEG data in a mobile communication terminal, and in particular, the present invention relates to resizing a non-standard size JPEG image for use in a mobile communication terminal while maintaining the original width:length ratio A technology that displays images on a display unit without distortion. Background technique [0002] Due to various functions of the mobile communication terminal, the mobile communication terminal has a built-in camera for taking a certain photo, which supports a function that allows the user to view the image through the album view. When a user captures an image through a mobile communication terminal, the image is captured and stored in a predetermined standard, such as VGA (640×480), QVGA (320×240), SQCIF (160×120), QCIF (176×144), MEGA (1280×1024), 2MEGA (1600×1200). The captured image signal is generally compressed by JPEG, stored in an...
