Abstract
Disclosed are an apparatus and a method for detecting an object automatically and estimating depth information of an image captured by an imaging device having a multiple color-filter aperture. A background generation unit detects a movement from a current image frame among a plurality of continuous image frames captured by an MCA camera to generate a background image frame corresponding to the current image frame. An object detection unit detects an object region included in the current image frame based on differentiation between a plurality of color channels of the current image frame and a plurality of color channels of the background image frame. According to an embodiment of the present invention, it is possible to automatically detect an object by a repetitively updated background image frame and to accurately estimate object information by separately detecting an object for each color channel by considering a property of the MCA camera.
