Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses that synthesize wide-angle images from multiple narrow-field lenses face significant processing loads and delays due to the need for extensive deformation and distortion correction across overlapping image regions, which complicates the alignment and synthesis of images.
Innovation Solution
An imaging apparatus comprising multiple imaging elements with overlapping fields of view, where pixel data from overlapping regions is prioritized for processing, allowing for early initiation of synthesis and reduced computational load through staggered readout directions and synchronized exposure times, enabling efficient image alignment and synthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If all pixel data from multiple imaging elements is processed sequentially in traditional order, then complete image synthesis can be achieved, but processing time is excessive and synthesis starts late
Solution Approach 1:
The patent applies preliminary action by prioritizing the output of pixel data from overlapping imaging ranges before other pixel data. The imaging elements are configured to output pixel data corresponding to overlapping positions first, enabling the synthesizing unit to start connecting processing at the synthesizing position in an early stage, thus reducing overall processing time and improving synthesis speed
2Manufacturing precision
If extensive deformation and distortion correction is applied to all image regions, then accurate image alignment is achieved, but computational load becomes very large
Solution Approach 1:
The patent applies segmentation by dividing the image processing into different priority levels. Pixel data from overlapping regions is processed first with full deformation and distortion correction to ensure accurate alignment, while other pixel data can be processed subsequently with reduced processing requirements, thus maintaining alignment accuracy while reducing overall computational load
Solution Approach 2:
The patent applies preliminary action by performing the most computationally intensive deformation and distortion correction operations on the overlapping region pixel data first, before processing other regions. This allows the synthesizing unit to establish accurate alignment early in the processing pipeline, reducing the need for extensive post-processing corrections

AI summary
An imaging apparatus that starts connecting processing at a synthesizing position in an early stage is provided. The imaging apparatus includes: a first imaging element that images a first imaging range, a second imaging element that images a second imaging range of which one part overlaps with the first imaging range, and a synthesizing unit that synthesizes an image corresponding to an imaging range wider than the first imaging range or the second imaging range, based on pixel data groups output by the first imaging element and the second imaging element, wherein the first imaging element and the second imaging element output pixel data corresponding to a position at which the first imaging range and the second imaging range overlap each other, to a synthesizing unit prior to other pixel data.
