Light Field Camera Focus Distance Timeline Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light field camera technologies face difficulties in making fine adjustments to focus distance in each frame of a moving image and visually confirming changes in focus distance over time.
Innovation Solution
An information processing apparatus and method that allows for easy setting of focus distance in each frame of a moving image by displaying a range of settable focus distances, utilizing a graphical user interface for light field moving images captured by a light field camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light field camera captures moving image with light field information, then in-focus position can be set as desired in each frame after shooting, but it is not easy to make fine adjustments to focus distance and difficult to visually confirm changes in focus distance over time
Solution Approach 1:
The patent introduces a time dimension to the focus distance adjustment interface by displaying focus distance ranges across multiple frames in a timeline view. This allows users to visually confirm focus distance changes over time and make fine adjustments more easily by interacting with the timeline representation rather than adjusting each frame independently.
Solution Approach 2:
The patent provides visual feedback by displaying the range of settable focus distances for each frame in the moving image. This feedback mechanism allows users to see the impact of their focus distance adjustments in real-time across different frames, making the adjustment process more intuitive and easier to control.
2Measurement precision
If focus distance is adjusted in each frame, then in-focus position can be set as desired, but visual confirmation of focus distance changes over time becomes difficult
Solution Approach 1:
The patent adds a temporal dimension to the focus distance display by showing focus distance ranges across frames in a timeline-based interface. This allows users to visually track focus distance changes over time, making it easier to detect and confirm precision adjustments across the entire moving image sequence.
Solution Approach 2:
The patent introduces a graphical user interface as an intermediary that displays focus distance ranges for each frame. This intermediary visualization layer bridges the gap between precise focus distance setting and visual confirmation, allowing users to easily detect and verify focus changes without direct complex measurements.
