RAW Still Image Extraction Without Stopping Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems require users to temporarily stop moving image reproduction to extract high-quality still images from RAW image data, increasing operational complexity and user workload.
Innovation Solution
An image processing apparatus and method that allows users to specify and extract still image data from RAW image data without stopping moving image reproduction, by using a frame position determining unit to identify the desired frame, a developing unit to process the RAW image data, and a still image encoding unit to compress and record the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users extract still images from RAW image data during moving image reproduction, then high-quality still images can be obtained, but operational complexity and user workload increase due to requiring temporary stops
Solution Approach 1:
The system performs preliminary actions by pre-processing the RAW image data during moving image recording and storage, so that when still image extraction is requested, the data is already prepared and can be quickly converted without requiring temporary stops or complex user operations
Solution Approach 2:
The system enables self-service by automatically managing the still image extraction process from RAW data without requiring user intervention to stop reproduction or initiate complex processing sequences, reducing operational complexity while maintaining high image quality
2Measurement precision
If users temporarily stop moving image reproduction to extract still images, then high-quality still images can be developed from RAW data, but processing efficiency and productivity decrease
Solution Approach 1:
The system maintains continuity of useful action by enabling still image extraction from RAW data to occur without interrupting the moving image reproduction process, allowing both functions to operate simultaneously and continuously, thereby improving processing efficiency while maintaining high image quality
Solution Approach 2:
By pre-processing and preparing the RAW image data during recording and storage phases, the system eliminates the need for time-consuming processing during extraction, allowing high-quality still images to be generated rapidly without compromising processing efficiency
3Speed
If compression encoded moving image data is used for still image extraction, then processing speed is improved, but picture quality deteriorates due to compression
Solution Approach 1:
The system changes the data parameter from compression-encoded format to uncompressed RAW image data format for still image extraction, thereby improving picture quality while maintaining efficient processing through optimized data access and pre-processing techniques

AI summary
An imaging processing apparatus includes a frame position determining unit configured to specify during a reproduction of developed first moving image data a frame position in the first moving image data of an image designated during the reproduction of the first moving image data by a user as an image to be extracted as a still image, a developing unit configured to read out undeveloped image data at a frame position adapted to the frame position specified by the frame position determining unit from undeveloped second moving image data corresponding to the first moving image data and develop the undeveloped image data, a still image encoding unit configured to compression encode the image data developed by the developing unit into a still image data, and a recording unit configured to record the still image data obtained by being compression encoded by the still image encoding unit onto a recording medium.
