A homogeneous region detector of an image using an adaptive threshold, and a method of the same. The homogeneous region detector includes a global region standard deviation calculation part to calculate a global region standard deviation of a whole region of an input image, a local region standard deviation calculation part to divide the input image into a predetermined number of local regions and to calculate a local region standard deviation of the each local region, and a homogeneous region determination part to separate the homogeneous region from a feature region in the input image using an adaptive threshold calculated based on entropy of the input image. Accordingly, the homogeneous region can be precisely detected by effectively separating the homogeneous region from the feature region of the input image by using the threshold adaptively calculated based on the entropy of the input image, so that the homogeneous region can be applied to various fields of image processing.
