内容記述 |
Movies have existed for over 100 years. But because of the unavoidability of age deterioration caused by the chemical instability of motion picture film, great quantities of valuable footage are being lost. Nitrate film used up to 1950 cannot escape age deterioration. Much of them have been damaged seriously. For these reasons, the digital preservation of motion picture film needs to include digital image processing technology for damage repair to restore images to their original pre-deterioration quality. This paper describes the development of robust and fast processing that is nearly ready for practical application. This was accomplished by integrating noise suppression technology, developed heretofore by us, for the suppression of flicker, blotches, scratches, and frame jitter, the main causes of age-related deterioration. Ordinarily, even if each noise repression process individually exhibits high performance, integrating them tends to result in an inability to maintain original image quality due to the effects of other noise. Our approach, comprising the investigation of the processing order and development of robust individual processes that resist other noise effects, enabled us to create integrated processing with high performance. Through computer simulations using actual movies, we demonstrated high-speed processing capable of real-time computation that delivers high image quality. |
