Camerawork Generation Using Reference Lines for Architectural Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video images generated for explaining architectural spaces lack comprehensibility and emotional involvement due to a monotonous and dull configuration, failing to effectively convey important design features and concepts to viewers.
Innovation Solution
A method for generating camerawork information that specifies a reference line between connected spaces in an architectural structure, using this line to determine time-series information for image-capturing position, direction, and movement, thereby creating a more engaging and comprehensible video image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional video image is generated by reproducing an arbitrary moving direction of a camera or camera object, then the video image has a continuous first-person point of view, but the video image configuration becomes dull and lacks comprehensibility
Solution Approach 1:
The patent segments the continuous video image into multiple shots with different camera positions and viewpoints. By dividing the video into discrete segments (shots) that capture different aspects of the space, the system maintains comprehensibility while avoiding the monotony of a continuous first-person perspective. Each shot is carefully composed to convey specific spatial information.
Solution Approach 2:
The patent transitions from a single first-person perspective to multiple dimensions of viewing by incorporating third-person viewpoints and varied camera positions. This dimensional change allows the video to convey spatial relationships more effectively by showing the space from multiple angles and perspectives, enhancing comprehensibility.
2Adaptability or versatility
If the point of view of the video image is changed at random to prevent viewer boredom, then the viewer is less likely to get bored, but the video image lacks comprehensibility and does not fully explain the space
Solution Approach 1:
The patent applies dynamic principles by varying camera positions, viewpoints, and shot compositions throughout the video. Rather than static or random changes, the camera work dynamically adapts to convey spatial relationships and architectural features. The system dynamically selects optimal camera positions and angles to maintain viewer engagement while ensuring comprehensive space explanation.
Solution Approach 2:
The system incorporates feedback mechanisms by analyzing the extracted space information and using it to guide camera positioning and shot composition. The feedback loop ensures that each camera shot is strategically placed to convey specific spatial information, balancing viewer engagement with comprehensibility through data-driven decision-making.
3Ease of manufacture
If a video image follows a monotonous camera path to maintain simplicity, then the video image is easy to generate, but the viewer lacks emotional involvement and gets bored
Solution Approach 1:
The patent employs periodic action by systematically varying camera positions and viewpoints at regular intervals throughout the video. This periodic variation in camera work creates visual interest and maintains viewer engagement while following a structured approach that remains relatively easy to generate. The systematic alternation between different shot types and camera angles prevents monotony.
Solution Approach 2:
The system changes multiple parameters including camera position, viewpoint angle, shot duration, and transition timing to create emotionally engaging video content. By varying these parameters in a coordinated manner, the patent achieves viewer emotional involvement while maintaining a systematic generation process that does not require excessive complexity.

AI summary
A method for generating camerawork information includes extracting, from design information of an architectural structure, a plurality of pieces of space information showing a plurality of spaces related to the architectural structure, specifying a reference line that passes through two connected spaces included in a space shown by a plurality of pieces of extracted space information and is used as a reference when a video image is configured, and generating camerawork information showing time-series information concerning at least one of an image-capturing position, an image-capturing direction, and an image-capturing movement direction in the two spaces on the basis of the specified reference line and the space information corresponding to each of the two spaces for which the reference line is specified.
