Video noise point compensating method and electronic device

CHINESE PATENT FOR SALE

This patent introduces a method and electronic device for compensating video noise points, aiming to enhance video clarity by reducing noise caused by low-light environments.

The method operates as follows:

  1. Obtaining Residual Data of the Video Frame
    • The system analyzes brightness variations within the current frame and across multiple frames.
  2. Generating Noise Point Strength
    • Uses intra-frame brightness standard deviation and inter-frame brightness residue to quantify noise intensity.
  3. Calculating a Residual Compensation Value
    • Determines the amount of correction needed to smooth out noise artifacts.
  4. Compensating Noise Points
    • Adjusts the affected areas based on the calculated compensation value, enhancing the final video quality.

Key Advantages

  1. Improved Video Clarity
    • Reduces graininess and distortion, especially in low-light conditions.
  2. Adaptive Noise Reduction
    • Dynamically adjusts compensation based on real-time noise detection.
  3. Enhanced Accuracy in Noise Correction
    • Uses quantified noise strength to optimize filtering without over-smoothing.
  4. Better User Experience in Video Calls and Streaming
    • Provides clearer and sharper video, making it ideal for video conferencing, live streaming, and surveillance.
  5. Minimized Impact of Poor Lighting
    • Ensures high-quality video even in dimly lit environments.

This patent presents an intelligent and adaptive solution for video noise compensation, ensuring better clarity and enhanced user experience.
