Abstract: Disclosed is a signal processing device, method of enhancing image signal, and an image display apparatus including the same. The signal processing device and the image display apparatus comprises: an image analyzer configured to receive a first image signal corresponding to displaying at least an object and a background, identify information of the object from the first image signal, and identify information of the background from the first image signal, and an object stereoscopic effect enhancement unit for enhancing the first image signal and configured to determine a sharpness of the object using the identified information of the object, increase contrast of the object to enhance the first image signal using the identified information of the object based on the determined sharpness, decrease luminance of the background in the enhanced first image signal using the identified information of the background based on the determined sharpness, and output the enhanced first image signal. Accordingly, a stereoscopic effect of an object may be enhanced.
