Immersive Video Color Correction Across Viewing Conditions

The patent implements dynamic chromatic adaptation models that adjust color correction parameters based on detected viewing conditions. The system transitions between different chromatic adaptation models (e.g., Bradford, von Kries) depending on whether immersive or non-immersive viewing is detected, allowing color perception consistency to be maintained across varying viewing scenarios without requiring a permanently complex processing pipeline.

The system changes key color processing parameters including chromatic adaptation model selection, white point values, and gamma curves based on viewing condition detection. By dynamically adjusting these parameters according to the viewing context (immersive vs. non-immersive), the patent maintains color consistency while keeping the base processing pipeline relatively simple.

The patent pre-computes and stores chromatic adaptation matrices and lookup tables for common viewing conditions. By preparing these computational resources in advance, the system avoids performing complex matrix operations and iterative calculations in real-time, thus achieving high color perception accuracy while minimizing processing time during actual video playback.

The system uses pre-defined chromatic adaptation models and matrices that replicate human visual system responses without requiring real-time physiological measurement. These standardized models (such as Bradford transformation matrices) serve as accurate copies of human color adaptation behavior, providing measurement precision equivalent to actual human perception without the computational burden of individualized calibration.

The patent implements a universal color correction framework that can operate with multiple chromatic adaptation models through a single unified processing pipeline. The system selects and applies the appropriate model (Bradford, von Kries, or other) based on detected viewing conditions, allowing one system to serve multiple viewing scenarios without requiring separate processing paths for each condition.

The system introduces a viewing condition detection module as an intermediary that automatically determines whether immersive or non-immersive viewing is occurring and selects the appropriate chromatic adaptation model accordingly. This mediator layer manages the complexity of multiple models by providing a simple interface that automatically routes to the correct processing path based on current viewing context.
