Abstract
An image enhancement method includes the following steps. Separating an original image signal into a high frequency image signal and a low frequency image signal by performing a wavelet transform through a first transformation circuit. Separating the high frequency image signal into a high frequency separation signal and a high-intermediate frequency separation signal by performing the wavelet transform through a second transformation circuit. Separating the low frequency image signal into a low-intermediate frequency separation signal and a low frequency separation signal by performing the wavelet transform. Enhancing high frequency separation signal to generate an enhanced high frequency separation signal configured to enhance the sharpness of an image. Through a inverse transformation circuit, integrating the enhanced high frequency separation signal, the high frequency separation signal, the low-intermediate frequency separation signal, and the low frequency separation signal into an enhanced image signal by performing the inverse wavelet transform.
