PURPOSE: An apparatus and a method for real-time image restoration by vaguelette-wavelet decomposition are provided to filter wavelet coefficient and to remove noise of an image by estimating a point-diffusion function. CONSTITUTION: A wavelet converting unit(110) performs discrete wavelet transform of an input original image. A noise cancelling unit(120) cancels the noise of the original image. A point diffusion function estimating unit(130) estimates coefficients which consist a point diffusion function of the original image. A vaguelette calculating unit(140) calculates a vaguelette base function. An image reconstruction unit(150) performs inverse wavelet transform.
