Multi-Depth Interval Refocusing via Device Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refocusing methods can only perform refocusing on a single depth plane, failing to meet user needs for multiple depth planes or intervals, and adding buttons or menus increases memory load without effectively addressing this requirement.
Innovation Solution
A multi-depth-interval refocusing method that allows users to select and refocus on at least two discontinuous depth intervals by acquiring user input, such as through touchscreen gestures or device posture operations, and processes the image to display a refocused image with visually distinguishable definition differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single depth plane refocusing method is used, then the device complexity is low, but the adaptability is insufficient to meet user needs for multiple depth planes
Solution Approach 1:
The patent introduces a new dimension of interaction by utilizing device posture (spatial orientation) to control refocusing. Instead of using traditional 2D touchscreen gestures or button presses, the system maps the 3D spatial posture of the device to select different depth planes for refocusing, thereby expanding the interaction dimension and enabling multi-depth refocusing without complicating the interface
Solution Approach 2:
The patent replaces mechanical interaction methods (buttons, menus, touchscreen gestures) with a posture-based control system. The device's physical orientation in space directly controls the refocusing operation, substituting complex mechanical interfaces with a more intuitive spatial control mechanism that naturally supports multiple depth planes
2Adaptability or versatility
If buttons or multi-level menus are added to enable multi-depth refocusing, then the refocusing capability is improved, but the ease of operation deteriorates due to increased memory load
Solution Approach 1:
The system uses the device's own physical properties (posture and orientation) to control the refocusing function. The device serves itself by leveraging its spatial state as the control input, eliminating the need for users to memorize button functions or navigate complex menus. The interaction becomes intuitive and self-explanatory based on the device's physical orientation

AI summary
Embodiments of the present invention provide a multi-depth-interval refocusing method, apparatus and electronic device. The method includes: displaying an image on a display device; acquiring user input, and determining, in the displayed image according to the user input, a refocus area including at least two discontinuous depth intervals, where each depth interval in the at least two discontinuous depth intervals is constituted by at least one depth plane, each depth plane contains at least one focus pixel, and depths of object points corresponding to focus pixels contained on the same depth plane are the same; performing refocusing processing on an image within the refocus area to display a refocused image on the display device, where the refocused image has a visually distinguishable definition difference relative to an area, except the refocus area, in the displayed image; and displaying the refocused image on the display device. Therefore, multi-depth-interval refocusing is implemented.
