AI Technical Summary

Technical Problem

Existing shake correction technologies in imaging devices are inaccurate due to feature points not accurately representing camera shake, especially with wide-angle lenses, and subjects far or high in the image having low spatial resolution, leading to incomplete shake correction.

Method used

An image processing apparatus that uses multiple optical systems to derive shake amount by detecting and matching feature points across images from different optical systems, applying extraction conditions to ensure accuracy, including subject presence in both views, appropriate image height, and distance range, and correcting for distortion.

Benefits of technology

Improves the accuracy of shake correction by ensuring feature points accurately represent camera shake, even with wide-angle lenses, by using multiple optical systems to enhance feature point detection and matching.

Abstract

Improve the accuracy of image stabilization. [Solution] The image processing device is an image processing device for deriving the amount of shake of an imaging device equipped with multiple optical systems, and comprises: acquisition means for acquiring a group of images captured at the same time, each of which is an image corresponding to one of the multiple optical systems; detection means for detecting feature points from each image in the group of images acquired by the acquisition means; extraction means for extracting target feature points to be used for deriving the amount of shake from among the feature points detected by the detection means; and derivation means for deriving the amount of shake based on target feature points extracted from a group of images captured at a first time corresponding to the same subject, and target feature points extracted from a group of images captured at a second time different from the first time, wherein the extraction means extracts a first feature point detected by the detection means from an image corresponding to one optical system as a target feature point, provided that a second feature point corresponding to the same subject as the first feature point is detected from an image corresponding to another optical system.
