1Productivity
If two sets of image processor circuits are disposed to support two-pixel mode, then the processing capability for high pixel rate images is improved, but the circuit area increases and one processor will be idle when two-pixel mode is not needed
Solution Approach 1:
The patent makes a single image processor circuit capable of performing multiple functions by supporting both two-pixel mode and picture-in-picture mode. The same processor circuit can process different input data streams for different display modes, eliminating the need for dedicated hardware for each mode and reducing overall circuit area while maintaining high processing capability when needed
2Productivity
If two sets of image processor circuits are disposed to support two-pixel mode, then the processing capability for high pixel rate images is improved, but one processor will be idle when two-pixel mode is not needed
Solution Approach 1:
The patent implements dynamic mode switching capability where the image processor circuit can adaptively change its operating mode based on real-time display requirements. The circuit transitions between two-pixel mode and picture-in-picture mode dynamically, ensuring that the processor remains actively utilized across different operational scenarios and avoiding idle states
3Area of stationary object
If a single image processor circuit is used, then the circuit area is reduced, but the processing capability for high pixel rate images in two-pixel mode is insufficient
Solution Approach 1:
The patent achieves enhanced processing capability within a single circuit by changing operational parameters such as clock frequency and data processing throughput. The image processor circuit operates at higher clock frequencies and processes data at increased rates to compensate for having only one processor, thereby maintaining high pixel rate image processing capability without requiring additional hardware
