Claim 14:
15. The bit rate control apparatus according to claim 14, wherein a method of calculating, by the calculation module, a distortion tolerance of each macroblock constituting the image to be encoded according to the difference between the reference distortion degree and the distortion degree of the feature region in the image to be encoded comprises:
obtaining a sum of the reference distortion degree, a difference between the distortion degree of the region of interest and the reference distortion degree, a difference between the distortion degree of the motion region and the reference distortion degree, a difference between the distortion degree of the complexity region and the reference distortion degree, and a difference between the degrees of distortion of the excessively bright or dark region in the image to be encoded and the reference distortion degree, and using the obtained sum as the distortion tolerance of the current macroblock.
