Omnidirectional Image Replay via Sensor-Recorded Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices fail to accurately record and replay omnidirectional images, requiring users to manually rotate or move the device to revisit previously viewed areas, and do not preserve the initial playback time point when replaying omnidirectional content.
Innovation Solution
An electronic device equipped with a display circuit, sensor circuit, and processor that provides an omnidirectional image larger than the screen, obtains direction changes using sensors, and stores time points correlated with frame information, allowing for seamless navigation and replay of omnidirectional content based on direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the omnidirectional image is replayed without recording movement information, then the replay function is simple, but the user cannot revisit previously viewed areas without manually rotating or moving the device
Solution Approach 1:
The system performs preliminary action by recording the initial direction and playback time point before replaying the omnidirectional image. This allows the device to automatically calculate and display the correct area during replay without requiring manual rotation, thereby improving ease of operation while adding minimal complexity through pre-recording metadata
Solution Approach 2:
The system creates a copy of the directional information and playback timing data associated with the omnidirectional image. During replay, this copied information is used to automatically position the display, eliminating the need for manual navigation and improving user convenience
2Area of stationary object
If the omnidirectional image size is larger than the screen, then more content is available, but only a partial area can be displayed at once requiring navigation
Solution Approach 1:
The system uses feedback from sensors to detect the current direction of the device and automatically adjusts the displayed area of the omnidirectional image accordingly. This real-time feedback mechanism allows the full large-size image to be available while the displayed portion automatically corresponds to the device's orientation, eliminating manual navigation needs
Solution Approach 2:
The system implements dynamics by making the displayed area adaptive rather than static. The displayed portion of the omnidirectional image dynamically changes based on the device's orientation and the recorded playback time, allowing the system to maintain both large image size and ease of access to specific areas
3Reliability
If the playback time point is not preserved during replay, then the replay function is simpler, but the initial viewing experience cannot be reproduced
Solution Approach 1:
The system performs preliminary action by recording the playback time point when the omnidirectional image is first played. This recorded time point is then used during replay to accurately reproduce the initial viewing experience, improving reliability while adding minimal complexity through simple time stamp storage

AI summary
An electronic device includes a display circuit, a sensor circuit, a processor, and a memory. The memory stores instructions, which when executed by the processor, cause the electronic device to provide an omnidirectional image having a size larger than the screen through the display circuit, to provide the screen with a first area being a partial area of the omnidirectional image, to obtain information of a change in a direction, which the electronic device faces, through the sensor circuit when the omnidirectional image is provided, to provide the screen with a second area being another partial area of the omnidirectional image through the display circuit based on the obtained information, and to store a time point, at which the direction is changed, wherein the time point is correlated with a time point or a frame at which the omnidirectional image is provided.
