Digital Camera Still Picture Extraction During Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies require laborious operations to extract and record multiple frames around a specific scene from moving pictures, limiting user convenience and flexibility in selecting desired images.
Innovation Solution
An image processing program and apparatus that allows for the extraction and recording of a predetermined number of frames before, after, or around a still picture extract command input during moving picture playback, enabling easy segmentation and recording of favorite scenes as continuous shooting, with optional frame and interval designation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a still picture is automatically extracted from the head of moving pictures at predetermined intervals, then the extraction process is automated, but a user cannot extract a desired scene
Solution Approach 1:
The system performs preliminary extraction of still pictures at predetermined intervals during playback, but allows users to modify the extraction by specifying timing adjustments. This combines automated preliminary action with user-controlled refinement, resolving the contradiction between automation and user selection flexibility.
Solution Approach 2:
The extraction timing is made dynamic by allowing users to adjust the predetermined intervals and specify exact moments for extraction. The system transitions from static automatic extraction to dynamic user-controlled extraction, enabling both automation and user flexibility.
2Device complexity
If only one specific scene can be recorded as a still picture, then the recording process is simple, but the user has to specify each image individually requiring laborious operation
Solution Approach 1:
The system segments the moving picture into multiple predetermined intervals and extracts still pictures at each interval automatically. This segmentation allows multiple images to be extracted without requiring individual specification, reducing operational complexity while maintaining simplicity.
Solution Approach 2:
The system performs self-service by automatically extracting and recording multiple still pictures at predetermined intervals without requiring user specification for each image. The system serves itself by managing the extraction process autonomously, eliminating laborious operations.
3Productivity
If a predetermined number of frames are extracted at predetermined intervals, then multiple images can be recorded, but the user cannot easily confirm extracted images on the same screen
Solution Approach 1:
The system merges the playback display and extracted still picture display into the same screen area. By combining these functions, users can confirm extracted images on the same screen where moving pictures are played back, improving convenience without sacrificing extraction efficiency.
Solution Approach 2:
The system adds a dimensional change by displaying extracted still pictures in a separate display area on the same screen. This allows simultaneous viewing of both moving pictures and extracted images without requiring separate screens, maintaining productivity while improving confirmation convenience.
Data Source
AI summary
Moving pictures are played back and displayed in a “moving picture display area” of a liquid crystal monitor. If a menu/OK button is pressed and a still picture extract command is issued during playback of moving pictures, then a predetermined number of frames of the still picture data obtained immediately before, immediately after, and before and after the moment when the still picture extract command is input is extracted together with the still picture data obtained at the moment when the still picture extract command is input from the moving picture data at predetermined intervals. Then, it is played back and displayed in a “still picture display area” of the liquid crystal monitor, and is recorded as a still picture file in a memory card.
