Image Pickup Device Parallax Correction Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image pickup devices with multiple-lens systems, slight differences in magnification, inclination, and distortion among images make accurate parallax correction difficult, leading to poor image quality and resolution in combined images.
Innovation Solution
The device includes a pre-image processing circuit that corrects differences in magnification, inclination, and distortion among images before combining them, using stored information on focal lengths, rotation angles, and distortion amounts to equalize these parameters, allowing for precise parallax correction and high-definition image formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple imaging optical systems are used to capture images, then image quality and resolution are improved, but differences in magnification, inclination, and distortion make accurate parallax correction difficult
Solution Approach 1:
The patent applies preliminary action by correcting differences in magnification, inclination, and distortion before performing parallax correction. The pre-image processing circuit equalizes these parameters across multiple images, creating standardized image data that facilitates accurate subsequent parallax correction and high-definition image combination.
2Productivity
If images are combined without correcting magnification and distortion differences, then processing time is reduced, but image quality and resolution deteriorate
Solution Approach 1:
The patent performs magnification and distortion correction as preliminary processing steps before image combination. By equalizing these parameters in advance through the pre-image processing circuit, the system enables efficient subsequent parallax correction and maintains high image resolution without requiring complex real-time adjustments during the combination process.

AI summary
A plurality of imaging regions (104, 105 and 106) capture a plurality of images, respectively, via a plurality of imaging optical systems (101, 102 and 103) corresponding one to one to the plurality of imaging regions. An image combining means (115) eliminates a difference among the plurality of images and combines the plurality of images into a single image. Thereby, it is possible to obtain a combined image of high quality.
