Mobile Camera Rewind Buffer for Missed Moment Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often miss capturing the perfect moment when using handheld computing devices due to the dynamic nature of the subject matter, leading to unnecessary storage of unwanted images and inefficient memory allocation.
Innovation Solution
A mobile image capture device that temporarily stores a video segment in a buffer and allows users to rewind and review image frames in reverse chronological order, enabling selective capture of desired moments without flooding storage with unwanted images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users capture a large number of images to ensure capturing the desired moment, then the probability of capturing the perfect shot increases, but storage space is wasted on unwanted images and memory allocation becomes inefficient
Solution Approach 1:
The system performs preliminary action by automatically capturing and buffering a sequence of images before the user actually presses the shutter button. This preliminary capture ensures that when the user does press the button, the desired moment is already recorded in the buffer, eliminating the need to capture excessive images in advance and thus preventing storage waste while ensuring the perfect moment is captured.
2Loss of substance
If users manually review and delete unwanted photographs from their collection, then storage space is freed up, but time is lost in the manual review process
Solution Approach 1:
The system performs self-service by automatically managing the image selection and storage process. After the user presses the shutter button, the system automatically presents the buffered images for selection, allowing the user to choose only the desired moments. This automated process eliminates the need for manual review and deletion of unwanted images, saving the user time while optimizing storage space utilization.
3Ease of operation
If the system buffers video segments from live stream, then rewind operation becomes possible for capturing missed moments, but temporary memory is consumed
Solution Approach 1:
The system applies the extraction principle by isolating and buffering only the specific video segment relevant to the user's capture intent, rather than buffering the entire live stream. By extracting and storing only the necessary portion in temporary memory, the system enables rewind functionality while minimizing temporary memory consumption to manageable levels.

AI summary
A mobile image capture device is provided that can include an image capture system operable to capture image frames and be configured to: provide a live video stream for display in a viewfinder portion of a user interface that depicts at least a portion of a current field of view of the image capture system; store a video segment from the live video stream in a temporary image buffer that includes a plurality of image frames captured by the image capture system; receive a user input that is directed to the viewfinder portion of the user interface that requests a rewind operation; and, in response to such user input, perform the rewind operation in the viewfinder portion of the user interface with respect to the video segment in which at least two of the image frames of the video segment can be provided for display in the user interface in a reverse chronological order.
