Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple virtual cameras are arranged to capture different viewpoints, then the range of expression in moving images is improved, but the complexity of integrating and coordinating multiple virtual cameras increases
Solution Approach 1:
The patent merges multiple virtual cameras into a unified system where they share common control mechanisms for movement and integration. The virtual cameras are coordinated through a single control flow that manages their positions, timing, and integration points, reducing the complexity that would otherwise arise from managing multiple independent camera systems.
Solution Approach 2:
The control system is designed with universal functionality to manage multiple virtual cameras through a single interface. The integration control unit can handle different camera configurations, movement patterns, and integration scenarios using the same basic control mechanisms, thereby reducing overall system complexity while maintaining versatility.
2Reliability
If virtual cameras are moved to integrate viewpoints, then seamless transitions between viewpoints are achieved, but the computational processing required increases
Solution Approach 1:
The system performs preliminary actions by pre-defining integration points and movement paths for virtual cameras. By planning the camera movements and integration sequences in advance, the system reduces real-time computational requirements while ensuring seamless transitions. The control unit prepares integration parameters before actual camera movements occur.
Solution Approach 2:
The patent maintains continuous useful action by ensuring that virtual camera movements and integrations occur smoothly without interruption. The control system manages the continuous flow of camera operations, maintaining consistent processing load rather than allowing sporadic high-computation events, thereby achieving seamless transitions with manageable computational requirements.

AI summary
There is provided an image processing apparatus, an image processing method, and a program capable of expanding the range of expression in a moving image generated by use of a 3D model. The image processing apparatus includes: a virtual camera setting unit that makes settings for a virtual camera; a virtual viewpoint image generation unit that generates a virtual viewpoint image that is an image of a 3D object viewed from a viewpoint of the virtual camera; a composition unit that generates a composite image based on a plurality of the virtual viewpoint images; and a moving image generation unit that generates a moving image including a frame based on the virtual viewpoint image or the composite image, in which after arranging a plurality of the virtual cameras, the virtual camera setting unit moves at least one of the plurality of virtual cameras to integrate the plurality of virtual cameras. The present technology can be applied to, for example, an apparatus that edits a moving image.
