LUT-Based Camera Preview for Easy Cinematic Tone Selection

The patent applies preliminary action by pre-configuring multiple LUT templates with different cinematic tone styles (such as Hollywood, European, Japanese styles) before the user needs them. These templates are stored in advance in the device memory, allowing users to simply select from pre-prepared options rather than adjusting parameters manually, thus enhancing ease of operation while managing device complexity through automated preprocessing.

The patent implements parameter changes by systematically varying color parameters (brightness, contrast, saturation, hue) across different LUT templates to create distinct cinematic styles. Each template contains pre-calibrated parameter sets that transform the preview image to match specific movie industry standards, allowing users to achieve professional-looking results through simple selection rather than complex manual adjustment.

The patent applies the extraction principle by isolating and storing only the essential color transformation data in LUT templates rather than storing complete image processing pipelines. Each LUT template contains condensed parameter sets that represent specific cinematic styles, extracting the core transformation rules needed for adaptability while minimizing memory storage requirements compared to storing full processing sequences.

The patent implements copying by creating multiple LUT templates that replicate proven cinematic color grading styles from different movie industries. Instead of developing unique processing algorithms for each style, the system copies and adapts established color transformation patterns into reusable templates, enabling versatility while reducing the computational and storage overhead of original research and development.
