Image Processing Apparatus Object Region Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image combining techniques face high processing loads when generating background images for combining multiple images, leading to issues with object disappearance in the final combined image.
Innovation Solution
An image processing apparatus that specifies difference regions in comparative images relative to a reference image, determines object regions, and combines objects from these difference regions with the reference image, using weighted averaging to preserve the main image objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional background image generation techniques are used to combine multiple images, then moving object portions can be extracted, but the processing load becomes excessively large
Solution Approach 1:
The patent extracts only the necessary difference regions between the reference image and comparative images, rather than processing entire background images. By identifying and extracting only the regions that contain moving objects (difference regions), the processing load is significantly reduced while maintaining the ability to combine multiple images effectively
Solution Approach 2:
The patent segments the image processing task into distinct components: identifying difference regions, determining object regions within those differences, and combining only the relevant object portions. This segmentation allows the system to avoid processing entire background images, thereby reducing overall processing complexity
2Productivity
If conventional image combining techniques are used, then multiple images can be processed, but objects may disappear in the final combined image
Solution Approach 1:
The patent applies partial action by combining images only in the specific difference regions where moving objects are present, rather than applying combination processing to the entire image. This selective approach ensures that objects are preserved in regions where they exist while avoiding unnecessary processing in background areas
Solution Approach 2:
Instead of generating a background image and subtracting objects from it, the patent inverts the approach by directly identifying difference regions and preserving objects within those regions. This inversion of the conventional approach prevents object disappearance by focusing on what needs to be preserved rather than what needs to be removed

AI summary
An image processing apparatus specifies, based on a reference image out of a plurality of images and a plurality of comparative images out of the plurality of images, a difference region, in each of the plurality of comparative images, including an object subjected to combination corresponding to a difference from a reference image, determines, based on a plurality of difference regions specified in the plurality of comparative images, an object region corresponding to an object included in the reference image, and combines, based on the determined object region in the reference image and the plurality of difference regions in the plurality of comparative images, with the reference image, the objects subjected to combination included in the plurality of difference regions so that an object corresponding to the object region is included in the reference image with which the plurality of difference regions are combined.
