Information Processing for Diaphragm-Based VFX Blur Matching

The patent applies preliminary action by acquiring the diaphragm value during the image capture process itself, before graphic generation occurs. This allows the blur shape information to be prepared in advance and used when generating graphics, ensuring that the blur characteristics are matched from the outset rather than attempting to correct mismatches afterward. The diaphragm value acquisition is performed as part of the shooting workflow, enabling real-time or near-real-time graphic generation with proper blur matching.

The patent uses the diaphragm value as an intermediary that bridges the real-world optical capture process and the digital graphic generation process. By extracting blur shape information from the diaphragm value (which is already part of the camera settings), the system creates a natural connection between the real object capture and graphic generation without requiring complex additional sensors or processing. This intermediary approach maintains process simplicity while achieving natural blur matching.
