Frame Synthesis Timing Control for AR Display Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In AR techniques, delays in frame generation lead to deviations in combined frames and reduced frame rates, making it difficult to maintain display content quality.
Innovation Solution
A display control apparatus that generates frames in synchronization with a predetermined synchronizing signal, allowing for the synthesis of current and past frames to maintain frame rate and content consistency, using a first frame generation section, a second frame generation section, and a synthesis section to handle timing discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frame synthesis is performed only when all frames are generated by specific timing, then synchronization is maintained, but frame rate reduction occurs when generation is delayed
Solution Approach 1:
The synthesis section performs frame synthesis in advance when frames are available, storing results for later display. This allows the system to maintain high frame rates by synthesizing frames before they are strictly needed, rather than waiting for perfect synchronization timing.
Solution Approach 2:
The system dynamically adjusts synthesis timing based on frame generation status. When frames are generated on time, synthesis occurs at specific timing; when delayed, synthesis uses available frames immediately. This dynamic adaptation resolves the contradiction between maintaining synchronization and preserving frame rate.
2Measurement precision
If frame synthesis waits for all frames to be generated, then accuracy is improved, but timing deviation increases
Solution Approach 1:
The system performs frame synthesis in advance when frames become available, rather than waiting for all frames to be perfectly generated. This preliminary action reduces timing deviation while maintaining acceptable synthesis accuracy through dynamic timing adjustment.
Solution Approach 2:
The synthesis timing parameter is changed dynamically based on frame generation status. The system transitions from fixed timing synthesis to flexible timing synthesis, adjusting the synthesis time parameter to balance accuracy and timing deviation requirements.
3Stability of the object's composition
If frame rate is reduced to eliminate display deviation, then content consistency is improved, but productivity decreases
Solution Approach 1:
The system dynamically adjusts synthesis timing to maintain display content consistency without reducing frame rate. By making synthesis timing flexible rather than fixed, the system preserves both consistency and high frame rate performance simultaneously.
Solution Approach 2:
The timing parameter for frame synthesis is changed from a fixed value to a dynamic value that adapts to frame generation conditions. This parameter change allows the system to maintain content consistency while operating at high frame rates.

AI summary
In an apparatus that synthesizes a plurality of frames, a deviation of display contents is not generated and reduction in a frame rate is suppressed. A first frame generation section generates a first frame whenever a period of a predetermined synchronizing signal has elapsed. A second frame generation section in turn generates a predetermined number of second frames. A synthesis section synthesizes, in a case in which a present frame that is the predetermined second frame is generated by specific timing, the present frame and the first frame and synthesizes, in a case in which the present frame is not generated by the specific timing, as a past frame, the second frame prior to the present frame with the first frame.
