IMAGE PROCESSING APPARATUS AND METHOD, AND IMAGE DISPLAYING APPARATUS |
摘要 |
<p>A first intermediate image generating means (1) generates an intermediate image (D1) by extracting a component of an input image (DIN) in a particular frequency band; a second intermediate image generating means (2) generates an intermediate image (D2) having a frequency component higher than intermediate image (D1); an intermediate image processing means (3M) generates an intermediate image (D3M) by suppressing low-level noise included in intermediate image (D1); an intermediate image processing means (3H) generates an intermediate image (D3H) by suppressing low-level noise included in intermediate image (D2); and an adding means (4) adds the input image (DIN) and intermediate image (D3M) and intermediate image (D3H) together to obtain a final output image (DOUT). Even if the input image includes a fold-over component on the high-frequency side or does not include an adequate high-frequency component, an enhanced image can be obtained without enhancing noise.</p> |
