Abstract
An apparatus for overlaying images includes a broadcast image layer generator, an application image layer generator, and an overlay processor. The broadcast image layer generator generates a broadcast image layer based on a received broadcast signal. The application image layer generator generates an application image layer based on an application image. The overlay processor generates an overlay image obtained by overlaying the broadcast image layer with the application image layer, so that a broadcast image corresponding to the broadcast image layer and an application image corresponding to the application image layer may be displayed simultaneously on a screen. The broadcast image and the application image may be displayed simultaneously on a screen, and visibility and readability of a text in the application image may be enhanced based on the user's preference and the user's recognition ability when the portable device performs multi-tasking in which multiple programs are simultaneously executed.
