Image Reproducing Apparatus Seamless Angle Change Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image reproducing apparatuses face challenges in performing seamless angle changes when angle change position information cannot be acquired from the currently-reproduced reproduction unit or when the acquired information is unsuitable, leading to interruptions in the reproduction process.
Innovation Solution
The apparatus includes an angle position information determination section and a control mechanism that utilizes stored angle change position information from other reproduction units to facilitate angle changes without stopping the reproduction, ensuring continuous playback by acquiring reproduction position information at the change destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If angle change position information is acquired from the currently-reproduced reproduction unit, then seamless angle change is enabled, but reproduction interruption occurs when the information is unavailable or unsuitable
Solution Approach 1:
The system performs preliminary actions by acquiring and storing angle change position information from future reproduction units (ahead of current playback position) before it is needed. This advance preparation ensures that when an angle change is requested, valid position information is already available, preventing reproduction interruptions and delays.
Solution Approach 2:
The patent introduces an intermediary mechanism (angle change position information storage and selection logic) that mediates between the current reproduction unit and the angle change operation. When current unit information is unavailable or unsuitable, the system selectively uses information from other reproduction units as an alternative source, ensuring continuous playback without interruption.
2Reliability
If angle change position information from other reproduction units is used, then continuous reproduction is maintained, but system complexity increases
Solution Approach 1:
The system implements self-service by automatically determining which reproduction unit's angle change position information to use based on availability and suitability criteria. The control logic autonomously selects information from the current reproduction unit or alternative units without requiring external intervention, maintaining reproduction continuity while managing complexity through automated decision-making.
3Productivity
If angle change position information is stored in advance, then angle change can be performed without stopping reproduction, but memory requirements increase
Solution Approach 1:
The system applies local quality by selectively storing and using angle change position information only from reproduction units that are relevant to current and near-future playback positions. Rather than storing information from all possible reproduction units, the system focuses on local (nearby) units, reducing memory requirements while maintaining the ability to perform angle changes without stopping reproduction.
Data Source
AI summary
An image reproducing apparatus for selectively reproducing and outputting image data of an arbitrary angle from image data of a plurality of angles including a plurality of reproduction units, comprising: an angle position information determination section which determines whether or not angle change is available based on angle change position information representing an address of an angle change destination recorded in the reproduction units; control means which changes an angle of a reproduced image data by using the angle change position information representing the address of the angle change destination recorded in the reproduction units; and angle change position information storage means which stores the angle change position information recorded in the reproduction units excluding a currently-reproduced reproduction unit at a currently-reproduced angle, wherein, if the angle position information determination section determines that the angle change cannot be performed by using the angle change position information recorded in the currently-reproduced reproduction unit, the control means changes the angle of the reproduced image data by using the angle change position information stored in the angle change position information storage means.
