Hybrid Video Camera Dubbing Guide Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video cameras with HDD systems require complex external devices for editing and dubbing functions, making them inconvenient to use, while DVD cameras have limited recording time and small monitor sizes hinder easy operation of dubbing functions on compact devices.
Innovation Solution
A hybrid video camera with both HDD and DVD capabilities, featuring a dubbing guide function on a compact monitor that allows users to select and execute dubbing operations directly on the device using intuitive 'All', 'Select', 'Date', and 'Un-dubbed' options, preventing erroneous selections through clear explanatory text and visual displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video cameras use HDD systems for dubbing functions, then recording capacity and flexibility are improved, but device complexity and operational difficulty increase due to requiring complex external editing devices
Solution Approach 1:
The patent integrates the dubbing function directly into the video camera body by combining the HDD recording unit with dubbing control capabilities. The control unit enables the camera to perform dubbing operations (copying selected video segments to separate storage) without requiring external editing devices, thus merging multiple functions into a single integrated system.
Solution Approach 2:
The video camera becomes self-sufficient for dubbing operations by incorporating its own control unit and storage management system. The camera can autonomously perform video selection, copying, and storage management without needing external editing equipment, allowing users to complete dubbing tasks directly with the camera itself.
2Weight of moving object
If DVD cameras use compact monitors for dubbing operations, then device portability is improved, but ease of operation deteriorates due to limited display size making selection difficult
Solution Approach 1:
The patent divides the dubbing operation into clear sequential steps displayed on the compact monitor: video selection, dubbing range specification, and execution confirmation. The control unit presents information in segmented, manageable portions that are easy to understand on small screens, breaking down complex operations into simple, guided steps.
Solution Approach 2:
The control unit acts as an intermediary between the user and the dubbing function, providing a simplified interface that translates complex operations into user-friendly display elements on the compact monitor. It mediates between the user's input and the system's functions, making operations easier despite the small screen size.
3Device complexity
If users select dubbing ranges on compact displays, then device integration is improved, but measurement precision deteriorates due to difficulty in accurately selecting video ranges
Solution Approach 1:
The control unit displays a preview or thumbnail representation of the video content before the user makes selection decisions. This preliminary visual information helps users accurately identify and select the desired dubbing range on the compact monitor, ensuring precise selection despite the limited display size.
Solution Approach 2:
The system provides real-time feedback to the user as they navigate and select dubbing ranges. The control unit displays confirmation information and visual indicators showing the selected range, allowing users to verify their selections and make adjustments if needed, thereby ensuring accurate range selection on the compact display.

AI summary
To provide an information recording and/or playback apparatus for dubbing onto a second recording medium all or some of plural pieces of information from a first recording medium in which the plural pieces of information are recorded. The apparatus includes a dubbing function that includes a plurality of dubbing functions respectively having different dubbing information selection methods. In the event of executing dubbing, identifiers enabling selection of one of the plurality of dubbing functions and a display screen for displaying an explanatory text regarding the respective dubbing function is displayed. In addition, when information is selected before the display screen is displayed, the information selection method of the respective dubbing function and an explanatory text to be displayed is changed corresponding to an information selection state.
