AI Technical Summary
Displays with HDMI interfaces often face issues such as picture distortion, inaccurate color performance, and loss of details when playing videos with incompatible video formats, as they can only support limited video formats like SDR or HDR types, leading to inconsistencies.
A video signal processing method that includes color space conversion, luminance mapping, color gamut conversion, and saturation mapping to adapt the video format to match the display capabilities, ensuring correct playback by performing these conversions in a sequence that reduces complexity and improves efficiency.
The method effectively converts video signals to compatible formats, preventing picture distortion and improving color accuracy, allowing displays to correctly play videos with inconsistent formats.
