Description

Automatic density correction has been used to correct density failure in printing color negatives. The method, however, is not always significant to correct color balance and density since the negative density which is used to calculate the correction coefficient is only measued in several fixed regions. In this paper, a new method is introduced to correct density failure considering the scene content. The complexity of the image calculated by using discrete Wavelet transformation with Haar function was applied to segment the negative film image dynamically. The densities of those obtained regions were measured and various parameters were calculated to correct printing color negatives. It is shown that the image manupulation method proposed in this paper is effective for density failure correction of 186 sample images.
