RAW Data Moving Image File Generation with Incidental Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing technologies face challenges in efficiently processing and handling moving image data, particularly in terms of processing speed and load, compared to still image data, which complicates image processing and quality adjustment.
Innovation Solution
An image capturing apparatus and data generating apparatus that generate moving image files by capturing RAW data with an imaging sensor and incorporating incidental information such as image capturing and property information, allowing for efficient handling and user-designated image processing adjustments, including continuous parameter changes between frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RAW data are used for moving images, then image quality and processing flexibility are improved, but processing speed and processing load deteriorate
Solution Approach 1:
The patent segments the moving image data by separating RAW data into individual frames and associating them with separate incidental information data. This allows processing to be performed frame-by-frame or in manageable groups, improving processing speed while maintaining the high quality benefits of RAW data.
Solution Approach 2:
The patent introduces incidental information data as an intermediary between the RAW data and the final processed image. This intermediary contains capturing conditions and parameter information that guides the processing, enabling efficient handling of RAW data by pre-organizing the information needed for processing.
2Measurement precision
If RAW data are used for moving images, then image quality and processing flexibility are improved, but processing load deteriorates
Solution Approach 1:
The patent performs preliminary action by capturing and recording incidental information data along with the RAW data. This includes capturing conditions (lens information, focus adjustment, focal distance) and parameter information that will be needed for processing. By preparing this information in advance, the actual processing load is reduced.
Solution Approach 2:
The patent utilizes parameter information from the incidental data to control processing parameters. By changing processing parameters based on the captured conditions (such as adjusting correction parameters based on focal distance), the system can optimize processing efficiency and quality without excessive computational load.
3Ease of operation
If incidental information data is added to each set of RAW data, then ease of handling and processing is improved, but data volume increases
Solution Approach 1:
The patent applies local quality by adding incidental information data specifically to each set of RAW data corresponding to individual frames or groups of frames. This localized approach ensures that only the necessary information is attached where needed, improving ease of handling without unnecessarily inflating data volume across the entire moving image.
Data Source
AI summary
An image capturing apparatus is provided with an image capturing unit and a generating unit. The image capturing unit includes an imaging sensor and captures a subject image to generate RAW data. The generating unit generates a moving image file including moving image data made up of a plurality of sets of RAW data which is generated by the image capturing unit, and incidental information data corresponding to each of the sets of RAW data and including at least one of image capturing information regarding the RAW data and property information of the RAW data. Accordingly, it is possible to generate the moving image data which is easy to be handled in image processing or image quality adjustment.
