Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video technology fails to accurately capture and display dynamic changes in scenes due to fixed frequency sampling, leading to over-sampling or under-sampling, redundancy, low time-domain resolution, and blurring, and existing display systems struggle to visualize pulse sequence signals without losing original information.
Innovation Solution
A display method that utilizes pulse signals represented by 0 and 1, determining display state information from the spatiotemporal relationship between target pulse sequences and a display array, and controlling display units to visualize these signals without traditional image reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional video technology uses fixed frequency sampling to capture scenes, then the sampling process is simple and systematic, but it results in over-sampling or under-sampling, large redundancy of video data, low time-domain resolution and blurring under high-speed motion
Solution Approach 1:
The patent transitions from fixed-frequency sampling to dynamic event-driven sampling. The imaging device captures scenes based on detected events (changes in optical signals) rather than at fixed time intervals. This allows the sampling rate to adapt dynamically to scene activity, improving time-domain resolution when motion occurs while reducing redundancy during static periods.
Solution Approach 2:
The patent changes the sampling parameter from fixed frequency to variable frequency based on event detection. The system adjusts sampling density according to the presence and intensity of detected events, transforming the sampling strategy from a static parameter to a dynamic one that responds to scene content.
2Loss of information
If existing display systems reconstruct target pulse sequence signals into image sequence signals for display, then the display process is compatible with traditional display devices, but the reconstruction process loses information carried by the original pulse signals and cannot accurately reproduce the change process of optical signals
Solution Approach 1:
The patent extracts and preserves the essential event information from the captured optical signals without performing full image reconstruction. By identifying and retaining only the critical temporal and spatial characteristics of detected events, the system avoids the information loss inherent in traditional reconstruction while maintaining compatibility with display devices.
Solution Approach 2:
The patent introduces an intermediate representation format that bridges the gap between pulse sequence signals and traditional image displays. This intermediate format preserves the temporal precision of pulse signals while being compatible with standard display interfaces, eliminating the need for lossy reconstruction.
3Adaptability or versatility
If traditional video technology captures scenes at preset fixed frequency, then the sampling approach is systematic and easy to implement, but it fails to reflect the dynamic changes of the scene accurately
Solution Approach 1:
The patent implements dynamic sampling by using event detection to trigger captures only when scene changes occur. This replaces the static fixed-frequency approach with a dynamic system that adapts to scene activity, improving adaptability while actually reducing overall system complexity by eliminating unnecessary captures during static periods.

AI summary
The present application discloses a display method based on pulse signals, an apparatus, an electronic device and a medium. The technical solution of the present application determines display state information of each display unit on a display device from a spatiotemporal relationship between target pulse sequences and a target display array, so as to realize complete display of the optical signal information recorded in the target pulse sequences, thereby facilitating accurate reproduction of the change process of optical signals of an original scene. Since the process does not involve traditional image reconstruction, the disadvantage of losing the information carried by the original pulse signals in the prior art is also avoided.
