Color Interpolation Method Using Grouped Channel Updates

The patent segments color components into groups (e.g., red and blue components in one group, green component in another) and updates different groups at different rates. This segmentation allows the system to maintain interpolation accuracy for critical color components while reducing computational operations for less critical components, thereby resolving the contradiction between accuracy and performance.

The patent applies partial action by updating only certain color components every pixel while copying other components from neighboring pixels. Instead of fully calculating all color components for every pixel (excessive action), the system performs partial calculations only where necessary, reducing computational load while maintaining acceptable picture quality.

The patent applies local quality by treating different color components differently based on their visual importance and update requirements. Critical components like green (which affects luminance) are updated every pixel, while less critical components like red and blue are updated every K pixels. This localized differentiation maintains picture quality where it matters most while reducing overall computational operations.

The patent implements periodic action by updating certain color components every K pixels rather than continuously every pixel. This periodic updating reduces the frequency of computational operations for non-critical color components, thereby improving processing speed while maintaining acceptable picture quality through strategic updates of essential components.
