Imager Metadata for Preprocessed Image Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in finding preprocessed image files among many stored images in imagers, as existing systems lack efficient search mechanisms for images that have undergone visual effects processing.
Innovation Solution
An imager equipped with an imaging sensor, image processor, and recorder that adds metadata to image files, including post-processing information, allowing for the creation of new image files after multiple visual effects processes, and enables searching for preprocessed images by utilizing unique metadata and a post-processing counter to differentiate between preprocessed and postprocessed files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If visual effects processing is applied to create enhanced images, then image quality and visual appeal are improved, but it becomes difficult to find the original preprocessed image files among many stored images
Solution Approach 1:
The system performs preliminary action by embedding post-processing information metadata into image files before storage. This metadata includes visual effect type, processing date, and other identifying information, enabling future easy retrieval of original images without requiring manual searching through numerous processed files.
Solution Approach 2:
The patent introduces an intermediary mechanism - a metadata system that acts as a bridge between processed images and their original counterparts. The post-processing information serves as an intermediary record that links enhanced images back to their source files, facilitating efficient search and retrieval operations.
2Adaptability or versatility
If multiple visual effects processes are carried out on image data, then creative flexibility and image variety are improved, but tracking and managing the processing history becomes complex
Solution Approach 1:
The system segments post-processing information into distinct metadata fields within the image file structure. Each visual effect processing step is recorded as separate information elements (effect type, parameters, date, time), allowing independent tracking and management of multiple processing operations without creating overall system complexity.
Solution Approach 2:
The patent utilizes parameter changes by encoding visual effects processing information as structured metadata parameters within image files. The system changes the state of image files by adding searchable parameters that describe processing history, enabling automated tracking and management of multiple visual effects applications without increasing operational complexity.
Data Source
AI summary
An imager is provided having an imaging sensor, an image processor, and a recorder. The imaging sensor creates an image signal by photographing a subject. The image processor processes the image signal with visual effects processing so as to create image data, and adds metadata to the image data so as to create an image file. The metadata contains post-processing information includes information based on the visual effects process. The recorder stores the image file. The visual effects process is used in processing the image data. The image processor conducting a post process in which more than one visual effects process is carried out, a new image file is created, and the new image file is stored in the recorder. The post-processing information has a post-processing counter and pre-processing information. The post-processing counter indicates the number of times the post process is carried out. The pre-processing information represents the state of a preprocessed image file prior to post processing.
