1Ease of operation

If manual input operations are used to search around a simulation screen for imaging conditions, then imaging conditions can be found, but it takes a long period of time

Engineering Contradiction:

Improvemanual search operationVSAvoidtime for location hunting

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically evaluates simulation images against desired captured images and identifies optimal imaging conditions without requiring manual searching. The evaluation unit automatically compares generated simulation images with target images to determine the best imaging parameters, making the system self-serve the location hunting task.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations (mouse and keyboard input) with an automated image processing system. The processor automatically generates simulation images, evaluates their similarity to desired images, and determines optimal imaging conditions, substituting human manual search with computational automation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If arbitrary-viewpoint image synthesis technology is used to reproduce event venues, then the venue can be confirmed from any position and direction, but it is difficult to examine captured images taking into consideration the position and size of actual subjects

Engineering Contradiction:

Improvearbitrary viewpoint confirmationVSAvoidsubject position and size accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system incorporates a feedback mechanism where simulation images are automatically evaluated against desired captured images. The evaluation unit compares the generated images with target images and uses this feedback to determine optimal imaging conditions, ensuring that subject position and size requirements are met.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes parameters of the simulation images by adjusting imaging conditions (position, angle of view, focal length) based on the evaluation results. The system modifies these parameters to optimize the simulation images so that they accurately represent the desired captured images with correct subject positioning and sizing.

Inventive Principle:
