To generate an image
First Claim
Patent Images
1. A method implemented by a printer apparatus to generate an image, the method comprising:
- determining, by the printer apparatus, a plurality of offset vectors for portions of a first image by comparing the similarity of the portions to portions of a second image;
determining, by the printer apparatus, the validity of a first offset vector of the plurality of offset vectors by comparing the first offset vector with other offset vectors of the plurality of offset vectors;
changing, by the printer apparatus, the first offset vector where the first offset vector is determined as invalid; and
generating, by the printer apparatus, an image by applying the plurality of offset vectors to the portions of the first image.

12. An apparatus to generate an image, the apparatus comprising a controller to:
-
determine a plurality of offset vectors for portions of a first image by comparing the similarity of the portions to portions of a second image; determine the validity of a first offset vector of the plurality of offset vectors by comparing the first offset vector with other offset vectors of the plurality of offset vectors; change the first offset vector where the first offset vector is determined as invalid; and generate an image by applying the plurality of offset vectors to the portions of the first image. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. Printer apparatus comprising:
-
a printer to print on media; a scanner to generate a scanned image of the printed media; a controller to determine a plurality of offset vectors for portions of a first image by comparing the similarity of the portions to the scanned image;
determine the validity of a first offset vector of the plurality of offset vectors by comparing the first offset vector with other offset vectors of the plurality of offset vectors;
change the first offset vector where the first offset vector is determined as invalid;
generate an image by applying the plurality of offset vectors to the portions of the first image; and
identify printing defects on the printed media by comparing the similarity of the scanned image with the generated image. - View Dependent Claims (20)
