Electronic Device Preview Frame Association Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras lose preview images stored in temporary storage when they are turned off, making it impossible to capture contextual information about the ambient circumstances along with the captured image.
Innovation Solution
An electronic device that extracts and stores at least one preview frame from a series of preview frames inputted through an image capturing device, associates it with the captured image, and displays both together, allowing for the retention of contextual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the camera stops running and preview images are stored in temporary storage, then the device saves memory resources, but the preview images are deleted and contextual information is lost
Solution Approach 1:
The patent extracts only the necessary preview frame (the frame closest to the captured image timestamp) from the sequence of preview frames and stores it permanently alongside the captured image. This selective extraction preserves the critical contextual information while avoiding the storage burden of keeping all preview frames, thus resolving the contradiction between information retention and memory resource consumption.
2Loss of information
If all preview frames are stored permanently, then contextual information is preserved, but storage space is excessively consumed
Solution Approach 1:
The system extracts only the single most relevant preview frame (the one whose timestamp is closest to the captured image timestamp) from the entire sequence of preview frames. This selective extraction maintains the essential ambient contextual information needed for understanding the captured image while minimizing storage space consumption by eliminating redundant preview frames.
Solution Approach 2:
The patent segments the continuous sequence of preview frames by identifying and selecting only the specific frame that corresponds to the captured image moment. This segmentation approach divides the large set of preview frames into individual frames, selects the most relevant one, and stores only that segment, thereby preserving information efficiently without storing the entire sequence.
3Quantity of substance
If preview images are deleted to free memory, then storage resources are released, but the ability to identify ambient circumstances is reduced
Solution Approach 1:
The patent extracts and permanently stores the specific preview frame that contains the ambient circumstance information (place, environment, other figures) associated with the captured image. By extracting only this essential contextual frame rather than deleting all preview images, the system releases memory resources while preserving the critical information needed to identify ambient circumstances.

AI summary
An electronic device and an operation method by the electronic device are disclosed. The electronic device includes a controller that controls to extract at least one frame of a plurality of preview frames inputted through an image capturing device and store an image captured through the image capturing device according to an image capturing request in association with the selected at least one frame; and a storage unit storing the captured image and the selected at least one frame.
