Imaging Apparatus Scene Change Detection via Panoramic Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face difficulties in efficiently detecting scene changes when transitioning from a low power consumption mode to an imaging standby mode, as they are not designed to handle changes in imaging direction effectively.
Innovation Solution
The method involves generating panoramic images from a series of images captured while changing the imaging direction, comparing these panoramic images at different times, and using the comparison results to determine scene changes and control the imaging apparatus, thereby deciding whether to exit the low power consumption mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging apparatus uses conventional scene change detection methods that compare only continuously-captured images, then the detection is simple and fast, but it cannot efficiently detect scene changes when transitioning from low power consumption mode to imaging standby mode due to imaging direction changes
Solution Approach 1:
The patent segments the image processing task by first generating panoramic images from multiple captured images, then comparing these panoramic representations rather than individual images. This segmentation allows the system to handle mode transitions effectively while maintaining manageable processing complexity.
Solution Approach 2:
The patent transforms the scene change detection from a temporal comparison (consecutive frames) to a spatial comparison (panoramic views). By creating panoramic images that represent wider fields of view, the system detects scene changes across different imaging directions, adding a spatial dimension to the detection process.
2Use of energy by moving object
If the imaging apparatus enters low power consumption mode to reduce energy consumption, then power savings are achieved, but scene change detection becomes inefficient when recovering to imaging standby mode
Solution Approach 1:
The patent performs preliminary action by generating panoramic images during the transition to low power consumption mode and storing them. When recovering to imaging standby mode, these pre-generated panoramic images are immediately available for comparison, enabling fast scene change detection without requiring extensive real-time processing during mode switching.
Solution Approach 2:
The patent creates panoramic image copies that represent the scene at different times and imaging directions. These panoramic copies serve as reference data for efficient comparison during mode transitions, allowing the system to detect scene changes without processing every individual frame during recovery from low power mode.
3Measurement precision
If the apparatus captures multiple images while changing imaging direction to create panoramic views, then scene change detection capability is improved, but the processing time and computational load increase
Solution Approach 1:
The patent addresses the time penalty by transforming multiple spatial images into a single panoramic representation. This dimensional transformation consolidates the information from multiple images captured at different directions into one comprehensive view, reducing the number of comparisons needed and thereby reducing processing time while maintaining detection precision.

AI summary
An imaging apparatus includes an imaging unit configured to capture an image, a generation unit configured to combine images to generate a panoramic image of a wider range than an imaging range of each image based on a plurality of images captured by the imaging unit while an imaging direction is being changed, a storage unit configured to store the panoramic image generated by the generation unit, and a detection unit configured to compare an image captured by the imaging unit and the generated panoramic image, and detect a change in a scene based on a comparison result.
