Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image communication interfaces face challenges in maintaining real-time image data display due to buffer size limitations, which are inadequate for varying pixel depths, leading to potential delays or overflow/underflow issues.
Innovation Solution
An electronic device with a control circuit that dynamically adjusts the delay time for outputting image data based on the bit depth of the input image data, ensuring the buffer operates within optimal levels to prevent delays, overflow, or underflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buffer size is designed to be large enough to store image data with maximum pixel depth (BPP=16), then the buffer can handle high-quality images, but the delay time for outputting image data becomes too long causing real-time display issues when small amount of data is transmitted (BPP=8)
Solution Approach 1:
The patent applies dynamics by making the buffer size adjustable rather than fixed. The buffer is configured to dynamically change its storage capacity based on the actual pixel depth of incoming image data. When BPP is low (e.g., 8), the buffer size is reduced to minimize delay time. When BPP is high (e.g., 16), the buffer size is increased to maintain reliability. This dynamic adaptation resolves the contradiction between buffer capacity and delay time.
Solution Approach 2:
The patent changes the parameter of buffer size based on the pixel depth parameter of incoming data. The system monitors the BPP value and adjusts the buffer capacity accordingly. This parameter change approach allows the buffer to optimize its performance characteristics (capacity vs. delay) based on the actual data requirements, resolving the technical contradiction between maintaining reliability and minimizing loss of time.
2Loss of time
If the buffer size is reduced to minimize delay time for small data transmission (BPP=8), then real-time display is improved, but the buffer cannot handle large data volumes with maximum pixel depth (BPP=16) causing overflow or underflow issues
Solution Approach 1:
The system dynamically adjusts buffer size in response to changing data conditions. When high-volume data with BPP=16 is detected, the buffer expands to prevent overflow and maintain reliability. When low-volume data with BPP=8 is transmitted, the buffer contracts to minimize delay time. This dynamic behavior ensures the buffer can handle both scenarios without experiencing overflow or underflow issues.
Solution Approach 2:
The buffer capacity parameter is changed based on the pixel depth parameter of incoming image data. The system monitors data characteristics and adjusts the buffer size parameter accordingly, allowing it to prevent overflow during high-data-volume transmission while minimizing delay during low-data-volume transmission.
3Device complexity
If a fixed buffer size is used, then the design is simple, but it cannot adapt to variations in pixel depth causing either excessive delay or overflow/underflow issues
Solution Approach 1:
The patent transforms the static buffer design into a dynamic one that automatically adapts to different pixel depth requirements. The buffer incorporates control logic that monitors incoming data characteristics and adjusts its capacity in real-time. This dynamic approach provides adaptability to various pixel depths while maintaining relatively simple overall system design through automated adjustment rather than complex manual configuration.
Solution Approach 2:
The buffer system performs self-adjustment based on the characteristics of incoming data. The control circuit automatically monitors pixel depth and adjusts buffer capacity without requiring external intervention or complex design configurations. This self-service mechanism provides adaptability to different pixel depths while keeping the design simple through automated operation.
