Solution Overview
Problem
The increase in information volume when recording image data with additional sensor information, such as camera motion and lens characteristics, poses a challenge in maintaining image quality and efficient data storage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor information and lens characteristics are directly added to image data, then image processing capabilities are improved, but the amount of information increases enormously
Solution Approach 1:
The patent extracts only the essential geometric deformation parameters from the vast amount of sensor information and lens characteristics. Instead of storing all raw sensor data and lens parameters, the system calculates and stores only the necessary deformation parameters that describe the geometric relationships, thereby reducing information volume while maintaining processing capabilities.
Solution Approach 2:
The patent transforms complex sensor information and lens characteristics into simplified geometric deformation parameters. This parameter transformation converts detailed physical measurements into a compressed representation that captures the essential geometric relationships, reducing data volume while preserving the necessary information for image processing.
2Reliability
If additional information about correction mechanisms and lens characteristics is included, then image quality is maintained, but the information volume is enlarged
Solution Approach 1:
The patent extracts only the essential geometric deformation parameters from the vast amount of sensor information and lens characteristics. Instead of storing all raw sensor data and lens parameters, the system calculates and stores only the necessary deformation parameters that describe the geometric relationships, thereby reducing information volume while maintaining processing capabilities.
Solution Approach 2:
The patent creates a simplified copy of the essential geometric relationships through deformation parameters. Rather than storing the complete complex data about correction mechanisms and lens characteristics, the system creates a condensed representation that captures the geometric deformation information needed for maintaining image quality.
3Ease of operation
If geometric deformation parameters are recorded for each frame, then image data can be processed with correction, but the recording complexity increases
Solution Approach 1:
The patent performs preliminary calculation of geometric deformation parameters during the image capture process. By pre-calculating these parameters and storing them with the image data, the system simplifies subsequent processing operations, as the deformation information is already prepared and available without requiring complex real-time calculations.

AI summary
An imaging sensor unit captures a subject through an optical system. A compression unit compresses image data continuously acquired from the image sensor unit to output to a recording unit. A feature amount extraction unit extracts a feature amount for each pixel of the image data and a coordinate selection unit selects a plurality of coordinates having a relatively high feature amount. A movement detection unit detects a movement vector of coordinate points according to the plurality of coordinates selected by the coordinate selection unit. A geometric deformation parameter generation unit generates a geometric deformation parameter based on the movement vector and lens information for the optical system. The recording unit records the geometric deformation parameter in association with the image data compressed by the compression unit (each frame of the image data).
