Abstract: The present invention relates to a mobile terminal and a method of controlling an operation of the same. The method of controlling an operation of a mobile terminal includes driving a web browser and access a specific website, displaying a web page provided by the specific website, and when any one of numeric enter keys is pressed, displaying an entry window for inputting a website address. Accordingly, a user interface of an intuitive and natural control fashion can be provided to a user.

Abstract: A method of controlling a mobile terminal is provided. The method includes displaying a first screen image, receiving weather information, providing a semi-transparent filter effect corresponding to the weather information, and overlaying the semi-transparent filter effect onto the first screen image to create a second composite image, and displaying the second composite image. A mobile terminal is also provided, which includes a display module configured to display a first screen image as an idle screen background, a wireless communication unit configured to receive weather information through a communication network, and a controller configured to overlay a semi-transparent filter effect corresponding to the received weather information onto the first screen image to create a second composite image, and then to display the second composite image.

Abstract: The present invention relates to a mobile communication device, method and computer program product for controlling a displayed screen using a rotary input device and an operating method thereof. The mobile communication terminal according to an embodiment includes a first input key, a second input key, a third input key, and a controller. The first input key generates a first signal when the first input key is turned. The second input key generates a second signal when the second input key is activated after the first signal is generated. The third input key generates a third signal when the third input key is activated after the first signal is generated. The controller controls a predetermined operation on a displayed screen based on at least one of the first signal, the second signal, and the third signal.
