Image Sensor Positioning for Validated Image Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographing apparatuses require an increased number of images to be taken to obtain high-resolution synthesized images due to inefficient invalidation determination methods, leading to higher calculation loads and potential image quality deterioration from changes in photographing conditions.
Innovation Solution
A photographing apparatus that moves the image sensor and optical element relative to each other to multiple positions, determining if captured images satisfy usage testing requirements, allowing for rephotography until requirements are met, and using these images to generate high-quality synthesized images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the invalidation determination is carried out by using the image at the origin when the lens unit is initially positioned at the origin and the image at the origin when the lens unit has returned to the origin, then the determination process is simple, but the number of photographs increases and calculation load increases
Solution Approach 1:
The patent applies preliminary action by performing invalidation determination at each relative position immediately after capturing images at that position, rather than waiting until all images are captured. This early determination allows the system to identify invalid images sooner and adjust the capture plan accordingly, reducing the total number of photographs needed while maintaining determination process simplicity
Solution Approach 2:
The patent segments the invalidation determination process into multiple stages, performing determination for each relative position separately as images are captured. This segmentation allows the system to evaluate images incrementally and stop capturing once sufficient valid images are obtained, thereby reducing the overall number of photographs required
2Device complexity
If the invalidation determination only checks the origin position images, then the determination process is simple, but image quality deteriorates when photographing conditions change
Solution Approach 1:
The patent performs preliminary invalidation determination at each relative position immediately after capture, allowing the system to detect changes in photographing conditions (such as object movement, vibration, or lighting changes) at each stage. This early detection ensures that images captured under deteriorated conditions are identified and excluded, maintaining high image quality for synthesis
Solution Approach 2:
The patent implements feedback by using the invalidation determination results from each relative position to inform subsequent capture decisions. When photographing conditions change and images are determined invalid, the system receives feedback to adjust capture parameters or reposition, ensuring that only high-quality images under stable conditions are used for synthesis
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces the number of images needed for high-quality synthesis and ensures image quality by determining image validity at each position, preventing image deterioration from changes in photographing conditions.

Data Source
AI summary
A photographing apparatus includes an image sensor configured to convert an object image formed by a photographing optical system, of the photographing apparatus, into electrical pixel signals, the photographing optical system including an optical element; and a photographing controller configured to control a photographing operation, in which a set of images for use in an image-synthesizing operation are photographed. During the photographing operation, the image sensor and the optical element are sequentially moved relative to each other from a reference position to relative positions in a direction different to a direction of the optical axis, wherein every time the photographing controller obtains a photographed image at each relative position, the photographing controller determines whether or not the photographed image satisfies usage testing-requirements for a constituent: image of the set of images. A photographing controller, a photographing control method, and a photographing control program are also provided.
