摘要

PURPOSE: A super-resolution image acquisition method by discrete wavelet conversion (DWT) conducts DWT about given image without down sampling, obtains high frequency sub bands of resolution such as the image, synthesizes high frequency sub bands and image through discrete wavelet inverse transform and obtains images of high resolution. CONSTITUTION: A program or an electronic circuit is input (S11) a low-resolution image. The program or the electronic circuit conducts sampling the low resolution image into same size through DWT and produces (S21) high frequency sub bands. The program or the electronic circuit assembles the low resolution image as low frequency sub band with high frequency sub bands. High-resolution image is obtained through the inverse DWT about the combined sub band (S61). [Reference numerals] (AA) Start; (BB) End; (S11) Input a low resolution image; (S21) Generate high frequency sub bands by sampling the low resolution image by same size DWT; (S61) Acquire a high resolution image by reverse DWT by combining the low resolution image and the high frequency sub band; (S71) Apply a block phenomenon removal filter to the high resolution image
