Interactive Camera Preview FoV Switching for Object-Centered Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to efficiently manage and enhance user interaction with displayed images and videos by allowing selective zoom and tracking of visual objects within varying field-of-views (FoVs), particularly in capturing and reproducing metadata associated with these interactions.
Innovation Solution
The electronic device incorporates a camera and display system that allows for the identification and selection of visual objects within a preview image, enabling the display and reproduction of videos based on a second FoV that includes the selected object, while associating metadata with the video obtained from a first FoV, thereby enhancing user interaction and experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device displays a preview image based on a first FoV and allows user selection of visual objects, then user interaction capability is improved, but device complexity increases due to multiple FoV management and metadata handling
Solution Approach 1:
The patent segments the field-of-view into multiple discrete FoV levels (first FoV, second FoV, etc.), each with its own metadata. This allows the system to manage complexity by treating each FoV as an independent unit with associated selection data, rather than managing a continuous or unstructured multi-foV system.
Solution Approach 2:
The patent performs preliminary actions by pre-obtaining and storing metadata for each FoV level before user interaction occurs. This includes pre-identifying visual objects and their corresponding FoV information, so that when users select objects, the system can quickly switch to the appropriate FoV without real-time computation delays.
2Adaptability or versatility
If the electronic device obtains and processes metadata for multiple FoVs, then image display flexibility is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by obtaining and preparing metadata for multiple FoV levels in advance, before user selection occurs. This pre-processing includes identifying visual objects and their corresponding FoV associations, so that during actual user interaction, the system can rapidly switch between FoVs using the pre-prepared metadata without time-consuming real-time processing.
3Adaptability or versatility
If the electronic device enables selection and zooming of visual objects within video, then user experience is improved, but ease of operation deteriorates due to complex FoV switching
Solution Approach 1:
The patent introduces metadata as an intermediary layer between the user interface and the actual FoV switching mechanism. This metadata acts as a mediator that translates user selections of visual objects into appropriate FoV changes, abstracting away the complexity of FoV management from the user while enabling sophisticated interaction capabilities.

AI summary
An electronic device receives a shooting input while displaying a preview image based on at least a portion of images obtained through a camera having a first field-of-view (FoV). The electronic device obtains a video of the first FoV through the camera, in response to the shooting input. The electronic device identifies a visual object included in the preview image, while obtaining the video. The electronic device displays the preview image, based on a second FoV that includes the visual object, and is included in the first FoV, in response to an input indicating selection of the visual object. The electronic device obtains meta data indicating reproduction of the video based on the second FoV corresponding to the input, among the first FoV and the second FoV, where the meta data is associated with the video obtained based on the first FoV.
