摘要 |
<p>The disclosed image enlargement device is provided with: an image enlargement filter (1) that enlarges an input image, generating a first enlarged image; a first wavelet transformation unit (2) that performs a wavelet transformation on the first enlarged image; a second wavelet transformation unit (3) that performs a wavelet transformation on the first enlarged image; and an accentuation processing unit (6, 7, 8, 10) that performs an accentuation process using a first edge signal (EDGE_CDF9/7), generated from the output of the first wavelet transformation unit, and a second edge signal (EDGE_Harr), generated from the output of the second wavelet transformation unit. The first wavelet transformation unit and the second wavelet transformation unit perform different wavelet transformations.</p> |
