Buffered Video Amount Visual Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture devices lack an intuitive interface to indicate the amount of video buffered for recording, making it unclear when or how much video has been stored.
Innovation Solution
An image capture device with a housing that includes a buffer memory and a display, where the buffered amount is visually indicated through a color progression along a path on the display, reflecting the buffered progress length, and changes upon capturing visual content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no visual indication is provided for buffered video amount, then the device complexity is reduced, but the ease of operation deteriorates as users cannot understand when or how much video has been buffered
Solution Approach 1:
The patent employs color progression along a path to visually indicate the buffered video amount. Different colors represent different buffering states, providing intuitive feedback to users without requiring complex numerical displays or additional controls. This resolves the contradiction by delivering clear operational information through simple color-based visual cues.
2Loss of information
If detailed information about buffered video is displayed, then the ease of operation improves, but the device complexity increases due to additional display elements and processing
Solution Approach 1:
The patent transforms the one-dimensional concept of buffered video amount into a two-dimensional visual representation using a path with color progression. This dimensional transformation allows comprehensive information display (buffered amount, recording status, capture timing) to be conveyed through spatial and color variations rather than multiple separate display elements, reducing overall system complexity.
3Productivity
If the interface provides real-time feedback on buffering status, then the productivity improves by helping users capture at optimal moments, but the use of energy increases due to continuous display updates
Solution Approach 1:
The buffered-amount element updates its color progression periodically or event-driven (when buffering status changes) rather than continuously refreshing. This periodic update mechanism provides necessary real-time feedback for recording efficiency while significantly reducing energy consumption compared to continuous display updates, resolving the contradiction between productivity and energy use.

AI summary
An image capture device may buffer video footage in a memory buffer before a command to record video is received. The image capture device may present a progression of color along a path to reflect the amount of buffered video footage. When the command to record the video is received, the video may be generated to include both buffered video footage and the video footage captured after the command.
