Abstract
A method of stitching an image to combine at least a first image and a second image in a digital image processing apparatus includes obtaining matching areas of the first image and the second image where the second image overlaps the first image, and changing gradations of an entire area of the second image to make a representative gradation of the matching area of the first image the same as a representative gradation of the matching area of the second image, wherein a change rate in changing at least one of the gradations of the entire area of the second image is set according to a level of a gradation of the second image before the changing the gradations of the entire area of the second image.
Claims19
A method of stitching an image to combine at least a first image and a second image in a digital image processing apparatus, the method comprising:
- obtaining matching areas of a first image and a second image where the second image overlaps the first image;
- changing gradations of an entire area of the second image to make a representative gradation of the matching area of the first image the same as a representative gradation of the matching area of the second image,
- wherein a change rate in changing at least one of the gradations of the entire area of the second image is set according to a level of a gradation of the second image before the changing the gradations of the entire area of the second image;
- and
- changing a gradation of each pixel of the matching area of the second image according to a gradation of a corresponding pixel of the matching area of the first image, and changing gradations of pixels of the second image close to a boundary line of the second image with respect to the first image to be similar to gradations of corresponding pixels of the first image.
A method of stitching an image to combine a plurality of images in a digital image processing apparatus, the method comprising:
- obtaining matching areas of a first image and a second image where the second image overlaps the first image;
- changing gradations of an entire area of the second image to make a representative gradation of the matching area of the first image the same as a representative gradation of the matching area of the second image, wherein a change rate in changing at least one of the gradations of the entire area of the second image is set according to a level of a gradation of the second image before the changing the gradations of the entire area of the second image;
- changing a gradation of each pixel of the matching area of the second image according to a gradation of a corresponding pixel of the matching area of the first image, and changing gradations of pixels of the second image close to a boundary line of the second image with respect to the first image to be similar to gradations of corresponding pixels of the first image;
- performing the obtaining the matching areas of the first and second images, the changing the gradations of the entire area of the second image and the changing the gradation of each pixel of the matching area of the second image with respect to all images;
- setting an image having a largest difference between a maximum gradation and a minimum gradation of all images before a gradation change, to be a reference image;
- and
- correcting all gradations of all images including the reference image by applying a degree of a change in a gradation of the reference image.
A method of stitching an image to combine a plurality of images in a digital image processing apparatus, the method comprising:
- obtaining matching areas of a first image and a second image where the second image overlaps the first image;
- changing gradations of an entire area of the second image to make a representative gradation of the matching area of the first image the same as a representative gradation of the matching area of the second image, wherein a change rate in changing at least one of the gradations of the entire area of the second image is set according to a level of a gradation of the second image before the changing the gradations of the entire area of the second image;
- changing a gradation of each pixel of the matching area of the second image according to a gradation of a corresponding pixel of the matching area of the first image, and changing gradations of pixels of the second image close to a boundary line of the second image with respect to the first image to be similar to gradations of corresponding pixels of the first image;
- performing the obtaining the matching areas of the first image and the second image where the second image overlaps the first image, changing the gradations of the entire area of the second image, and changing the gradation of each pixel of the matching area of the second image with respect to all images;
- setting an image of all the images that is selected by a user, to be a reference image;
- and
- correcting all gradations of all images including the reference image by applying a degree of a change in a gradation of the reference image.
