Registration of separations
View Patent ↗Images may be registered using temporal (time-based) and spatial information. In a film implementation, because film is a sequence of frames, using information from neighboring frames may enable a temporally smoother visual experience. In addition, it may be beneficial to take advantage of the fact that consecutive frames are often shifted similarly during the photographic process. Distortion measures may be used that discount candidate transformations that are considered to be too far from one or more preferred transformations, such as, for example, an optimal transformation from another frame or block or a currently-optimal transformation from the same frame/block. Composite color images may be processed to provide registration of underlying components.
1. An apparatus having stored thereon at least the following:
information relating to an image in a sequence of images, the information configured to allow generation of a first component image of the image and a second component image of the image, the first and second component images including first and second content, respectively, relating to a specific portion of the image,
wherein:
the second component image has been transformed to reduce misregistration between the first and second component images as compared to misregistration between the first component image and a prior version of the second component image, the transformation having been based on registration information from another image in the sequence of images,
the first component image comprises a first color separation,
the second component image comprises a second color separation, and
displays of the first color separation and the second color separation are configured to collectively form at least part of a single resultant image.
2. The apparatus of claim 1 wherein the second component image comprises analog information.
3. The apparatus of claim 1 wherein the second component image comprises digital information.
4. The apparatus of claim 1 wherein the first color separation is a digital color separation.
5. The apparatus of claim 1 wherein the second component image is part of a frame in a film.
6. The apparatus of claim 1 wherein the apparatus comprises a reel.
7. The apparatus of claim 1 wherein the apparatus comprises a video.
8. The apparatus of claim 1 wherein the apparatus comprises an optical disc.
9. The apparatus of claim 1 wherein the apparatus comprises a computer readable medium.
10. The apparatus of claim 1 wherein the second component image has been indirectly transformed by being based on one or more images that have been directly transformed.
11. The apparatus of claim 10 wherein:
the second component image is one of a set of corresponding images stored in a YUV format,
the set of corresponding images, including the second component image, is based on another set of corresponding images having an RGB format, and
one or more of the other set of corresponding images has been directly transformed to reduce misregistration between two or more images of the other set of corresponding images, whereby the second component image is indirectly transformed by being based on the one or more images that have been directly transformed.
12. The apparatus of claim 1 wherein the information includes encoded information configured to be decoded to generate the first and second component images.
13. The apparatus of claim 12 wherein the first and second component images are interleaved with each other.
14. A method of generating component images comprising:
accessing information relating to an image in a sequence of images; and
generating a first component image of the image and a second component image of the image based on the accessed information, the first and second component images including first and second content, respectively, relating to a specific portion of the image,
wherein:
the second component image has been transformed to reduce misregistration between the first and second component images as compared to misregistration between the first component image and a prior version of the second component image, the transformation having been based on registration information from another image in the sequence of images,
the first component image comprises a first color separation,
the second component image comprises a second color separation, and
displays of the first color separation and the second color separation are configured to collectively form at least part of a single resultant image.
15. The method of claim 14 wherein the first color separation is a digital color separation.
16. The method of claim 14 wherein the second component image has been indirectly transformed by being based on one or more images that have been directly transformed.
17. The method of claim 16 wherein:
the second component image is one of a set of corresponding images stored in a YUV format,
the set of corresponding images, including the second component image, is based on another set of corresponding images having an RGB format, and
one or more of the other set of corresponding images has been directly transformed to reduce misregistration between two or more images of the other set of corresponding images, whereby the second component image is indirectly transformed by being based on the one or more images that have been directly transformed.
18. The method of claim 14 wherein the information includes encoded information configured to be decoded to generate the first and second component images.
19. The method of claim 18 wherein the first and second component images are interleaved with each other.
20. A system comprising:
means for accessing information relating to an image in a sequence of images; and
means for generating a first component image of the image and a second component image of the image based on the accessed information, the first and second component images including first and second content, respectively, relating to a specific portion of the image,
wherein:
the second component image has been transformed to reduce misregistration between the first and second component images as compared to misregistration between the first component image and a prior version of the second component image, the transformation having been based on registration information from another image in the sequence of images,
the first component image comprises a first color separation,
the second component image comprises a second color separation, and
displays of the first color separation and the second color separation are configured to collectively form at least part of a single resultant image.
