Reduction of differential resolution of separations
First Claim
1. A method of reducing differential resolution, the method comprising:
- selecting a first image containing first information about a scene;
selecting a second image containing second information about the scene, wherein a portion of the first image and a portion of the second image have differential resolution;
determining a location at which to modify a property of the first image to reduce the differential resolution, the location being in the portion of the first image, and the determination being based on information obtained at least in part from the portion of the second image; and
reducing the differential resolution by modifying the property at the determined location in the portion of the first image, wherein the first image and the second image comprise color separations of a film frame.

Abstract
Certain disclosed implementations use digital image processing to reduce the differential resolution among separations or images in film frames, such as, for example, red flare. A location in the red image may be selected using information from another image. The selected location may be modified using information from that other image. The selection may include comparing features of an edge in the first image with features of a corresponding edge in the other image. The modification may include performing wavelet transformations of the two images and copying certain coefficients (or a function of these coefficients) produced by the application of the transformation to the second image to the coefficients produced by the application of the transformation to the first image. The copied coefficients may be correlated with the selected location. Other disclosed techniques vary from the above and may be applied to other fields.
