Display Control Apparatus Guide Information for Recording Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for image data recording do not provide users with adequate guide information during shooting, particularly in high-frame-rate recording modes, making it difficult for users to know the recording duration and timing, leading to missed shots or interrupted recordings.
Innovation Solution
A display control apparatus that includes an acquiring unit, an accepting unit, and a switching unit, which allows for switching between recording modes and displays guide information that increases or decreases with time based on the recording instruction, enabling users to know the recording duration and timing in both start and end triggers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If guide information is not displayed during shooting, then the device complexity is reduced, but the user cannot know the recording duration and timing
Solution Approach 1:
The patent uses color changes in the display unit to indicate recording status and duration. The display shows guide information with different colors to represent different recording states (e.g., recording in progress, recording completed, buffer full), providing intuitive visual feedback without complex controls
Solution Approach 2:
The patent introduces a buffer as an intermediary between the imaging unit and recording medium. The buffer temporarily stores captured images, allowing the system to decouple the recording process from the display process, enabling guide information display without affecting recording operations
2Adaptability or versatility
If the recording mode switches between start trigger and end trigger, then the adaptability is improved, but the user cannot know how long recording has been made
Solution Approach 1:
The patent implements feedback by continuously displaying guide information in the display unit that shows the current recording status and duration. The display updates in real-time to reflect the current recording mode (start trigger or end trigger) and provides visual feedback about how long recording has been made or how much time remains
Solution Approach 2:
The patent makes the display information dynamic by changing its content and characteristics based on the current recording mode. In start trigger mode, the display shows elapsed time increasing; in end trigger mode, it shows remaining time decreasing. This dynamic adaptation allows the same display system to provide appropriate information for different recording modes
3Productivity
If the recording time is limited in advance, then the productivity is improved, but the user misses shots when the recording time is insufficient
Solution Approach 1:
The patent performs preliminary action by pre-allocating a buffer for storing captured images and setting a maximum recording time limit. This allows the system to prepare for recording in advance, knowing the available capacity and time, while still allowing flexible recording within those constraints. The buffer is ready to receive images immediately when recording starts
Solution Approach 2:
The buffer acts as an intermediary that decouples the recording time limit from the actual shot capture. Even when the recording time limit is approached, the buffer continues to temporarily store images, allowing the system to maintain reliable capture throughout the recording period while managing overall productivity through the time limit
Data Source
AI summary
A display control apparatus includes a recording control unit that controls recording data acquired from a recording unit so as to be recorded on a first recording unit, an accepting unit that accepts an instruction concerning recording from a user, and a control unit that controls the recording data acquired from the recording unit before the instruction is accepted so as to be recorded upon acceptance of the instruction by the accepting unit and that controls display corresponding to the amount of recording data to be recorded on the first recording unit so as to be displayed in a display unit before the accepting unit accepts the instruction.
