ABSTRACT:
A screen scroll apparatus of a portable device includes: a sensor unit which senses and outputs 2-dimensional coordinate values of at least one position related to the portable device; a display unit; a memory storing contents with a resolution higher than that of the screen that can be displayed; and a control unit which scrolls the screen based on the 2-dimensional coordinate values if the 2-dimensional coordinate values change when contents are read from the memory and provided to the display unit. A screen scroll method includes: if a resolution of contents displayed on the portable device is higher than a resolution of a screen that can be displayed, monitoring 2-dimensional coordinate values of at least one position related to the portable device output from the sensor unit; and if the 2-dimensional coordinate values change, scrolling a screen displayed on the portable device based on the 2-dimensional coordinate values.
