Engineering Contradiction Analysis
1Measurement precision
If image processing apparatuses perform Fourier transform operations to generate hologram images, then the quality and resolution of hologram images are improved, but the computation time and power consumption increase significantly
Solution Approach 1:
The patent divides the hologram generation process into multiple segments corresponding to different pixel regions. Each segment is processed independently and simultaneously through parallel computation, allowing the overall computation to be completed faster while maintaining full image quality.
Solution Approach 2:
The patent introduces a temporal dimension to the processing architecture by implementing multi-frame processing. Multiple frames are processed in parallel across different time steps, effectively distributing the computational load and reducing the time required for each individual hologram generation while preserving image quality.
2Measurement precision
If image processing apparatuses perform Fourier transform operations to generate hologram images, then the quality and resolution of hologram images are improved, but the power consumption increases significantly
Solution Approach 1:
The patent segments the computational workload into multiple independent processing units that can operate in parallel. This distribution of computation across multiple units reduces the power consumption burden on any single processing element while collectively achieving high-quality hologram generation.
Solution Approach 2:
The patent implements a processing architecture where not all pixels are processed to the same level of detail simultaneously. Some regions are processed with higher precision while others use optimized approximations, reducing overall power consumption while maintaining perceptually adequate image quality.
3Measurement precision
If portable devices perform Fourier transform operations for hologram generation, then hologram image quality is maintained, but the device size and weight constraints are violated due to limited processing capability
Solution Approach 1:
The patent divides the processing task into smaller segments that can be handled by compact processing units suitable for portable devices. This segmentation allows high-quality hologram generation without requiring a single large, power-intensive processor.
Solution Approach 2:
The patent performs preliminary processing of image data before hologram generation, pre-computing certain parameters and organizing data in a format optimized for subsequent parallel processing. This preliminary action reduces the computational burden on the portable device during actual hologram generation.
