Face Image Recording Apparatus for Individual Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image recording technologies do not effectively associate and record the extracted face image with the original image, making it difficult to identify individuals in images, especially when multiple faces are present.
Innovation Solution
A face image recording apparatus and method that includes a face detecting device to identify faces within original images, an extracting device to isolate and process these faces, and a recording control device to store face image data on a separate medium in association with the original image data, allowing for clear identification and display of individual faces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If face images are extracted and recorded separately, then individual identification capability is improved, but device complexity and data management complexity increase
Solution Approach 1:
The patent embeds face image data within the original image file structure, creating a nested data organization where extracted face images are stored as embedded components within the parent image file. This allows individual identification through face images while maintaining data integrity and reducing management complexity through unified file handling.
Solution Approach 2:
The patent introduces an image processing apparatus as an intermediary that automatically extracts face images, processes them, and embeds them within original images. This intermediary automates the complex tasks of face detection, extraction, and data association, improving individual identification while masking the underlying data management complexity from users.
2Loss of information
If multiple face images are extracted and recorded, then completeness of individual identification is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs face image extraction and processing as a preliminary action during or immediately after image capture, rather than as a post-processing step. By detecting faces and extracting their images in advance, the system ensures complete individual identification data is ready when needed, while distributing processing load to reduce time loss.
Solution Approach 2:
The patent extracts and processes only the necessary portions of images (face regions) rather than entire images. By focusing computational resources on detecting and extracting only face-containing regions, the system achieves complete individual identification for all persons in the image while significantly reducing overall processing time and computational requirements compared to processing full images.
Data Source
AI summary
The image of a face is cut from an image obtained by image sensing. Original image data is read from a memory card and the portion of the original image that is the image of the face is extracted by trimming. The image of the face is subjected to correction and other processing. Data representing the image of the face thus processed is recorded on the memory card. Thus, the original image and the image of the face are recorded on the memory card. The original image and the image of the face can be displayed by reproducing the data recorded on the memory card.
