INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18320281 titled 'INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM

Simplified Explanation

The patent application describes a system for generating virtual viewpoint images based on user operations and key frame information.

  • The system includes a virtual viewpoint operating unit that collects time codes, positions, and orientation information on virtual viewpoints designated by the user.
  • This information is then registered with a key frame setting unit.
  • A virtual viewpoint variation measuring unit detects abrupt changes in the virtual viewpoint path based on the key frame information stored in a key frame storing unit.
  • If a precipitous section is detected, an image generating method determining unit determines how to generate a virtual viewpoint image between the key frames.
  • This determination is based on variations in virtual viewpoint parameters measured by the virtual viewpoint variation measuring unit and the registered parameters of the key frames.
  • A playback speed adjusting unit can modify the key frame information and store the updated information again.


Original Abstract Submitted

A virtual viewpoint operating unit obtains time codes, positions and orientation information on virtual viewpoints, and the like to be designated as key frame information based on a user operation, and registers the information with a key frame setting unit. A virtual viewpoint variation measuring unit detects a precipitous section in a virtual viewpoint path based on the key frame information stored in a key frame storing unit. In a case where the precipitous section is detected in the virtual viewpoint path, an image generating method determining unit determines a method of generating a virtual viewpoint image between the key frames based on variations of virtual viewpoint parameters measured by the virtual viewpoint variation measuring unit and the registered virtual viewpoint parameters of the key frames. A playback speed adjusting unit changes the key frame information and stores the changed key frame information again.
