Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for treating visual dysfunctions rely on hardware devices like signal delay circuits and optical paths, which are costly and inflexible, making it difficult to adjust time differences between visual stimuli for individual user needs.
Innovation Solution
A method and system that process frame sequences by replacing repetition frames with mask frames to create a time difference between visual stimuli for the left and right eyes, reducing reliance on hardware and allowing flexible parameter adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware devices such as signal delay circuits and delayed optical paths are used to control time difference between visual stimuli, then stable sequence of visual stimuli is achieved, but additional costs and device complexity increase
Solution Approach 1:
The patent replaces hardware-based signal delay circuits and optical delay paths with a software-based frame sequence processing method. By manipulating the presentation timing of frames in a display sequence and using mask frames to control visual stimulus timing, the system achieves the same functional effect without mechanical or electronic hardware delays, thereby reducing device complexity and cost while maintaining reliability
Solution Approach 2:
The patent changes the approach from hardware parameter adjustment (delay circuit values, optical path lengths) to software parameter control (frame presentation timing, mask frame positioning). This allows flexible adjustment of time differences between visual stimuli through digital parameters rather than physical hardware modifications
2Reliability
If hardware devices are used to control time difference between visual stimuli, then stable sequence is achieved, but flexibility to adjust parameters is reduced
Solution Approach 1:
The patent introduces dynamic adjustability through software-based frame sequence processing. The time difference between visual stimuli can be dynamically changed by modifying frame presentation timing and mask frame positions in the display sequence, allowing the system to adapt to different user needs and conditions without requiring hardware reconfiguration
Solution Approach 2:
The patent creates a universal solution that can handle multiple scenarios (different time differences, different mask frame configurations, different presentation timings) through a single software-based framework. This multi-functional approach replaces multiple hardware configurations with one adaptable system
3Reliability
If additional hardware devices are coupled to display devices, then time difference control is achieved, but costs increase
Solution Approach 1:
The patent substitutes expensive hardware components (signal delay circuits, optical delay paths) with a software-based frame processing approach that uses existing display device capabilities. This eliminates the need for additional hardware manufacturing and integration while maintaining precise time difference control through digital frame sequencing
Solution Approach 2:
The patent uses mask frames - temporary, software-based visual elements that exist only for the duration of frame presentation. These mask frames serve as a low-cost, disposable mechanism to control visual stimulus timing without requiring permanent hardware additions to the display system

AI summary
The present technology provides a method and apparatus for processing a frame sequence, and a system for treating visual dysfunction. The method comprises: acquiring original frame sequences of a left eye channel and a right eye channel, the original frame sequences comprising a number of groups of consecutive frames, and each group of consecutive frames comprising a variety of repetition frames; and replacing part of the repetition frames in the left eye channel and/or the right eye channel with mask frames, and obtaining target frame sequences of the left eye channel and the right eye channel. When the target frame sequences of the left eye channel and the right eye channel are presented simultaneously, the setting of the mask frames enables the visual stimulus of the original frames of the left eye channel to the left eye to be consistently ahead of or lag behind the visual stimulus from the original frames of the right eye channel to the right eye, and thus the visual stimuli received by the left and the right eye has a stable sequence. The technical solution of the present technology allows reduced reliance on hardware devices for producing offsets between the left and right eye visual signals, thereby saving costs while allowing flexible adjustments of parameters to meet the needs of individual users.
