Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging technologies require significant processing power and time to combine panned images of moving subjects by comparing and extracting regions with similar pixel values and patterns, making the image positioning and combining process inefficient.
Innovation Solution
An imaging apparatus and method that uses high-frequency components to select and position images, employing a reference region with high-frequency blocks to minimize the number of motion vectors needed for image combination, thereby simplifying and speeding up the process of generating panned images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image comparison and region extraction processing is performed to determine reference regions for positioning multiple images, then accurate image positioning and combination is achieved, but processing power consumption increases and processing time extends
Solution Approach 1:
The patent extracts only the essential high-frequency components from images to serve as reference regions, rather than performing comprehensive image comparison. By extracting motion vectors specifically from high-frequency blocks (edges, corners, textures) and using these as reference regions for positioning, the system achieves accurate image alignment while significantly reducing processing time and computational load.
2Reliability
If comprehensive image comparison is performed to extract consecutive regions with similar pixel values and patterns, then reliable reference regions are identified, but device complexity increases
Solution Approach 1:
The patent applies local quality by focusing processing only on high-frequency blocks (edges, corners, texture regions) rather than uniformly processing entire images. These specific local regions contain sufficient information for reliable motion vector extraction and image positioning, thereby reducing overall processing complexity while maintaining identification reliability.

AI summary
An imaging apparatus includes: an imaging section configured to acquire a plurality of images that are consecutively taken in time series by an imaging device; a reference region setting section configured to employ one of the images acquired by the imaging section as a reference image and to set a region of the reference image as reference region, the region having high-frequency components; and an image processing section configured to combine the images including the reference image by positioning the images so as to overlap subject portions in each images, the subject portions being defined in the reference region set by the reference region setting section.
