Claim:
1. An apparatus for detecting a motion mask, the apparatus comprising: an image processor configured to generate a plurality of image frames; a first motion mask detector configured to detect at least one first motion mask by calculating a local feature of each pixel included in a partial or entire area of at least one current image frame which indicates a pixel value relationship between the each pixel and at least one neighboring pixel, and comparing the calculated local feature with a local feature of a corresponding pixel of at least one previous image frame; a second motion mask detector configured to detect at least one second motion mask based on a difference between the partial or entire area of the current image frame and a corresponding area of the previous image frame; and a motion mask generator configured to generate a final motion mask comprising at least one of the first motion mask and the second motion mask.
