Nebula Master Engine Introduction

Intelligent content recognition for enhanced detail in both bright and dark areas

Based on the grayscale histogram of the image, divide the image content into six types of scenes and classify them according to brightness and darkness; then adjust the gamma curve for each frame of the image to enhance the contrast, making the details of light and dark areas richer.

Dual grayscale correction to ensure grayscale consistency

The light source and display grayscale of each projector are calibrated to ensure that the Gamma coefficient of 2.2 and the color point can accurately achieve the best grayscale consistency. This ensures that the brightness of the device display matches the input signal and the grayscale performance of the picture achieves the best effect.

Ten-Thousand-Level Color Calibration

Utilizing our independently developed color calibration algorithm, we perform individual color calibration for each device using a 3D Color Lookup Table (3D LUT) for 260,000 colors (64³) before it leaves the factory. This ensures that every device displays colors accurately and consistently, achieving a color difference of less than 1 (ΔE < 1).

Image Smoothing and De-banding

To eliminate or reduce the contouring effect or banding effect in images, which typically appear in areas with color gradients, especially in cases of lower color depth.

By employing edge detection algorithms to identify regions affected by the contouring effect, and subsequently applying smoothing filters, the abrupt changes in color or brightness can be mitigated through weighted averaging. This process ensures that the transitions in brightness and color are more natural, while preserving the edge details of the image during the smoothing process.
