AI Imaging Sensor Output That Blocks Raw Image Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging sensors can only output signal processing results, leaving a risk of privacy invasion due to the potential exposure of image data.
Innovation Solution
An imaging apparatus that includes a signal processing unit to delete image data after processing and an output unit that only transmits signal processing results, or includes a checking process to ensure image data is not included in the output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If image data is output to the outside, then the imaging apparatus provides complete data access, but privacy invasion risk increases
Solution Approach 1:
The patent extracts only the necessary signal processing results from the image data while leaving the original image data within the device. The output unit is configured to output only signal processing results, not the complete image data, thereby providing necessary information access while protecting privacy.
Solution Approach 2:
The patent segments the data flow into two distinct paths: one for signal processing results that can be output, and another for original image data that remains internal. This segmentation is achieved through the signal processing unit and output unit configuration, separating useful information from sensitive data.
2Object-affected harmful factors
If only signal processing results are output, then privacy protection is improved, but data access completeness deteriorates
Solution Approach 1:
The signal processing unit acts as an intermediary that transforms complete image data into processed results. This intermediary process extracts essential information while removing sensitive details, allowing external systems to receive useful data without accessing raw image data.
Solution Approach 2:
The patent changes the parameter of data output from complete image data to processed signal results. This parameter change maintains the usefulness of the output for analysis and processing while fundamentally reducing the privacy risk by altering what information is exposed.
3Measurement precision
If image data is stored for processing, then processing accuracy is maintained, but privacy risk increases
Solution Approach 1:
The patent performs preliminary signal processing on the image data before any potential output. By preprocessing the data to extract only necessary results and deleting the original data, the system maintains processing accuracy while preemptively eliminating privacy risks.
Solution Approach 2:
The signal processing unit deletes image data after signal processing is completed. This discarding of original data after extraction of necessary information maintains processing accuracy (since processing was already done) while eliminating subsequent privacy risks from data storage or transmission.

AI summary
The present disclosure relates to an imaging apparatus and a data output method capable of reducing the risk of privacy invasion.An imaging unit, in which a plurality of pixels are two-dimensionally aligned, configured to capture an image, a signal processing unit configured to execute signal processing for image data based on an output of the imaging unit, an output unit, which is not directly connected to the imaging unit, configured to be able to output only a signal processing result of the signal processing to the outside are included, and the signal processing unit deletes the image data after the signal processing. The present disclosure can be applied to an image sensor in which an AI function is mounted.
