Abstract
Abstract An image processing system assigns weight factors to two respective image signals of the equivalent color space so that the two image signals are combined according to the respective weight factors. For example, two weight factors having a sum of unity are assigned to the respective image signals. Alternatively, two weight factors are assigned independently.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
An image processing apparatus comprising: first color conversion means for converting plural sets of color-decomposed signals representing a plurality of images into plural sets of equivalent color space signals; image processing means for combining the plural sets of equivalent color space signals to produce a set of combined equivalent color sapce signals representing a combined image; and second color conversion means for converting the set of combined equivalent color space signals into a set of colorant signals to be used for reproducing the combined image, the image processing means receiving two sets of equivalent color space signals and comprising means for assigning two weight factors having a sum of unity to the two respective sets of equivalent color space signals so that the two sets of equivalent color space signals are combined according to the respective weight factors.
Claim 2
Dependent Claim
138 words
An image processing apparatus comprising: first color conversion means for converting plural sets of color-decomposed signals representing a plurality of images into plural sets of equivalent color space signals; image processing means for combining the plural sets of equivalent color space signals to produce a set of combined equivalent color sapce signals representing a combined image; and second color conversion means for converting the set of combined equivalent color space signals into a set of colorant signals to be used for reproducing the combined image, the image processing means receiving two sets of equivalent color space signals and comprising means for assigning two weight factors having a sum of unity to the two respective sets of equivalent color space signals so that the two sets of equivalent color space signals are combined according to the respective weight factors.
Claim 3
Dependent Claim
22 words
