Digital Camera Simultaneous Still and Video Recording Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras face challenges in seamlessly integrating still-image and moving-image photographing processes, particularly in identifying and reproducing simultaneously captured images during concurrent operations, which affects user convenience and efficiency.
Innovation Solution
A digital camera system with a memory unit for recording image data, a judging unit to determine if images were captured simultaneously, and an advising unit to notify users of available still or moving images, allowing for user-friendly reproduction of images only when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If still-image photographing is performed during moving-image photographing by suspending the moving-image process, then still-image quality is improved, but moving-image continuity deteriorates
Solution Approach 1:
The patent segments the photographing process into distinct modes (still-image mode and moving-image mode) with clear state transitions. The controlling unit manages separate operation flows for each mode, allowing the system to switch between them based on user input without interference, thus maintaining still-image quality while preserving moving-image continuity through proper state management.
Solution Approach 2:
The patent implements preliminary actions by preparing the system state before mode switching. When a still-image photographing instruction is received during moving-image photographing, the system preliminarily suspends the moving-image process, executes the still-image capture, and then resumes the moving-image process, ensuring both operations can be performed with optimal quality.
2Adaptability or versatility
If multiple image data are recorded simultaneously, then photographing versatility is improved, but image identification difficulty increases
Solution Approach 1:
The patent employs feedback mechanisms where the reproducing unit provides information about recorded image data to the user. When still-image data is reproduced during moving-image reproduction, the system provides notifications or visual feedback indicating the presence and timing of captured still images, enabling users to easily identify and select specific images without confusion.
Solution Approach 2:
The patent introduces an intermediary information layer (such as timing markers, metadata, or visual indicators) that mediates between the multiple image data stored in memory and the user's perception. This intermediary system organizes and presents the image data in a way that makes identification straightforward, distinguishing between still images and moving image frames through clear signaling.
Data Source
AI summary
A still image is photographed by a still image photographing operation performed during a moving-image photographing operation and a moving image is photographed during the moving-image photographing operation. The still image is recorded together with link information indicating the moving image to be linked with and the moving image is recorded together with link information indicating the still image to be linked with. Further, a timing information is recorded for indicating a photographing time when the still-image photographing operation is performed during the moving-image photographing operation. In an operation for reproducing the moving image, when a still image is prepared to be linked with the moving image, a still image mark M1 is displayed during a period from five seconds before to five seconds after the photographing timing. Upon manipulation during such period, the still image is displayed. In an operation for reproducing the still image, when a moving image to be linked with the still image is available, a moving image mark M2 is displayed. Upon manipulation, the moving image is reproduced from a position of the moving image corresponding to the photographing time.
