Device and method for displaying a zoom screen in a mobile communication terminal

#This application claims priority to an application entitled “DEVICE AND METHOD FOR DISPLAYING ZOOM SCREEN IN MOBILE COMMUNICATION TERMINAL”, filed in the Korean Industrial Property Office on Apr. 22, 2002 and assigned Serial No. 2002-22057, the contents of which are incorporated herein by reference.

#1. Field of the Invention

#The present invention relates to a device and method for displaying image data, and more particularly to a device and method for adjusting a received camera image signal captured according to a size of a display screen of a display unit, and displaying the adjusted image signal.

#The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

#FIG. 1 is a block diagram illustrating an example of components for a mobile communication terminal in accordance with an embodiment of the present invention;

#FIG. 2 is a block diagram illustrating an example of the components of a signal processor shown in FIG. 1 in accordance with an embodiment of the present invention;

#Several embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same or similar elements are denoted by the same reference numerals.

#Those skilled in the art will appreciate that specific criteria such as a size of pixels of image signals captured by a camera, a size of pixels of image signals capable of being displayed on a display unit, a transmission rate of an image signal, and so on are described only for illustrative purposes to help in understanding the present invention. The present invention can also be implemented without those specific criteria.

#It is also noted that the term “image capture mode” refers to an operating mode for capturing image signals through a camera and displaying the captured image signals on a display unit. The term “enlarged screen display mode” refers to an operating mode for enlarging pixels of the captured image signals in the image capture mode and displaying the enlarged pixels on the display unit. The term “first scale control signal” refers to a control signal for reducing the number of image signals captured by the camera and displaying the reduced image signals on a screen of the display unit. The term “second scale control signal” refers to a control signal for selecting some image signals of a specified area from the image signals captured by the camera and displaying the selected image signals on a zoom screen. The term “first display screen” refers to a screen for displaying reduced pixels of the image signals captured by the camera in response to the first scale control signal, and the term “second display screen” refers to a screen for selecting predetermined image pixels from an image of the image signals captured by the camera in response to the second scale control signal and displaying the selected image pixels on the zoom screen. The term “preview” refers to an operation of displaying the image signals captured by the camera in the form of a moving picture. The term “still-picture capture mode” refers to an operating mode for capturing a still picture in a preview state.
