Image processing apparatus, image processing method, and storage medium

An image processing method for generating a panoramic image by combining a plurality of images in a partially-overlapping manner, comprising:

• acquiring a position of a boundary line for combining a first image and a second image partially overlapping the first image in an overlap region, the first image and the second image being two of the plurality of images;
• detecting an edge component of an object in vicinity of the position of the boundary line in either of the first image and second image;
• setting a blend width of a region, in the overlap region and including the boundary line, where pixel values of pixels constituting the first image and pixel values of pixels constituting the second image are blended, wherein the blend width is set based on the position of the boundary line and the edge component;
• and
• combining the first image and the second image by blending the pixel values of the pixels constituting the first image and the pixel values of the pixels constituting the second image, in the region of the set blend width in the overlap region.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute an image processing method for generating a panoramic image by combining a plurality of images in a partially-overlapping manner, the image processing method comprising:

• acquiring a position of a boundary line for combining a first image and a second image partially overlapping the first image in an overlap region, the first image and the second image being two of the plurality of images;
• detecting an edge component of an object in vicinity of the position of the boundary line in either of the first image and second image;
• setting a blend width of a region, in the overlap region and including the boundary line, where pixel values of pixels constituting the first image and pixel values of pixels constituting the second image are blended, wherein the blend width is set based on the position of the boundary line and the edge component;
• and
• combining the first image and the second image by blending the pixel values of the pixels constituting the first image and the pixel values of the pixels constituting the second image, in the region of the set blend width in the overlap region.
