Abstract: PURPOSE: An apparatus and a method for extracting a foreground layer in an image sequence are provided to automatically track a layer area in subsequent frames through user's setting in a start frame in the image sequence in which the depth values of the foreground and the background are discontinuous, thereby extracting the foreground layer area in which the drift phenomenon and the flickering phenomenon are reduced. CONSTITUTION: An image sequence receiving unit (110) receives an original image sequence photographed by a camera. An initial area designating unit (120) designates a plurality of control points on a contour of a layer area in image data for each frame based on a selection input. A layer area tracking unit (130) generates a foreground layer area by connecting the designated control points and tacks the generated foreground layer for each frame. An alpha map generating unit (150) connects respective control point coordinates by a curve generation scheme in all frames in which the layer area is tracked, and generates an alpha map by determining an internal area as the layer area.
