Solution Overview
Problem
Existing automatic imaging technologies fail to adjust compositions naturally when a subject's movement direction or orientation changes during lectures, leading to undesirable framing results.
Innovation Solution
An information processing device that calculates a target composition based on a subject's state and transitions smoothly or instantaneously to maintain appropriate framing, using units for posture acquisition, orientation determination, size determination, movement determination, and composition transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the composition is adjusted immediately when the subject's orientation changes, then the framing responds quickly to the subject's state change, but the composition transition becomes unnatural and jerky
Solution Approach 1:
The patent applies dynamics by making the composition transition mode adaptive rather than fixed. The system dynamically switches between smooth transition mode and instantaneous transition mode based on the subject's state change characteristics. When the subject's orientation changes gradually, smooth transition is used to maintain naturalness. When the subject's orientation changes abruptly, instantaneous transition is used to respond quickly. This dynamic adaptation resolves the contradiction between response speed and transition naturalness.
2Stability of the object's composition
If the composition transitions smoothly to the target composition, then the framing appears natural, but the response to rapid subject orientation changes becomes delayed
Solution Approach 1:
The system dynamically adjusts the transition mode based on the magnitude and speed of subject state changes. For rapid orientation changes that would cause excessive delay with smooth transition, the system switches to instantaneous transition mode, thereby reducing response time while maintaining natural appearance for gradual changes.
Solution Approach 2:
The patent changes the transition parameter (transition mode) based on the subject's state change characteristics. By monitoring the speed and magnitude of orientation changes, the system adjusts the composition transition parameter to select between smooth and instantaneous modes, optimizing both response time and naturalness according to the specific situation.
3Stability of the object's composition
If the framing always maintains space on one side of the subject, then the composition is consistent, but it becomes inappropriate when the subject changes orientation frequently
Solution Approach 1:
The patent makes the composition adaptive by dynamically recalculating the target composition based on the subject's current orientation. Instead of maintaining a fixed composition rule, the system continuously updates the desired composition to match the subject's state. This allows the framing to adapt to frequent orientation changes while maintaining appropriateness, resolving the contradiction between consistency and adaptability.

AI summary
An information processing device (10) includes a target composition calculation unit (16) and a composition transition determination unit (17). The target composition calculation unit (16) calculates a target composition based on a state of a subject. The composition transition determination unit (17) switches a transition mode for transition to the target composition between a smooth composition transition mode and an instantaneous composition transition mode based on a situation of a change in state of the subject. The smooth composition transition mode is a transition mode in which a composition gradually transitions to the target composition. The instantaneous composition transition mode is a transition mode in which the composition instantaneously transitions to the target composition.
