Virtual Filming Background Optimization for On-Site Lighting Match

The patent applies preliminary action by pre-rendering background images with embedded lighting information before filming. The lighting data is prepared in advance and integrated into the background resource, so that during filming, the terminal device can directly apply the pre-calculated lighting effects without requiring time-consuming post-production synthesis. This resolves the contradiction by performing the computationally intensive work beforehand, reducing both post-production time and cost while maintaining high film result quality.

The patent uses copying by creating digital replicas of lighting information and embedding them into background images. Instead of expensive physical lighting setups and manual post-production matching, the system copies lighting data from reference images and integrates it digitally into the background resource. This digital copying approach maintains high film result quality while significantly reducing production costs by eliminating the need for complex physical lighting equipment and manual post-production work.

The patent introduces an intermediary solution by embedding lighting information directly into the background image resource as metadata. This intermediary layer carries the lighting data from the reference image through to the terminal device during filming. The terminal device uses this embedded lighting information to apply accurate lighting effects on-site, eliminating the need for complex post-production matching while maintaining simplicity in the filming process. The intermediary lighting data bridge ensures both operational simplicity and lighting effect accuracy.
