Imaging Device Recording Status Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging devices often cause discrepancies between the contents actually recorded and the user's assumptions due to lack of clear visual feedback regarding the recording status, leading to user confusion.
Innovation Solution
The imaging device displays a green pause mark initially, which changes to a red pause mark upon receiving a recording command, and further changes to a red now-recording mark after a predetermined time, providing clear visual feedback on the recording status through color changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a light-emitting means blinks to indicate recording start and progress, then the device provides visual feedback, but the feedback is insufficient and causes user confusion about actual recording status
Solution Approach 1:
The patent applies color changes to the display mark to indicate different recording statuses. The mark displays green when recording is not in progress, yellow when recording will start after a predetermined period, and red when recording is actually in progress. This color-coded system provides clear, intuitive visual feedback that eliminates user confusion about the actual recording status.
Solution Approach 2:
The patent implements a multi-stage feedback system that provides continuous visual information about the recording status. Instead of a single blink signal, the system provides sequential feedback through mark display (green→yellow→red) that clearly communicates each stage of the recording process, from standby to actual recording, ensuring the user understands what the device is actually doing.
2Ease of operation
If the device starts recording after a predetermined period following operation acceptance, then the device provides time for user preparation, but the delay creates uncertainty about when recording actually begins
Solution Approach 1:
The patent uses preliminary action by displaying the yellow mark before recording actually starts. This intermediate visual signal warns the user that recording will begin after a predetermined period, allowing them to prepare (e.g., position the camera, ensure proper framing) while clearly indicating that recording has not yet commenced. This resolves the uncertainty about timing by providing advance notice.
Solution Approach 2:
The patent implements periodic action through the sequential display of marks at different stages. The system cycles through green (standby) → yellow (recording will start soon) → red (recording in progress), providing periodic visual updates that keep the user informed about the timing and status of recording operations throughout the predetermined delay period.
Data Source
AI summary
The imaging device has a display section, an imaging section configured to generate an image of an object, an operation section configured to accept an operation, and a record control section. The record control section starts recording of video image data based on the generated image after a predetermined operation through the operation section is accepted and a predetermined period of time passes thereafter. Until the operation section accepts the predetermined operation, the display section displays a first mark in a first form. Until the predetermined period of time passes after acceptance of user operation thorough the operation section, the display section displays the first mark in a second form. After the predetermined period of time passes, the display section displays a second mark different from the first mark.
