Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems struggle to effectively adjust illumination and capturing ranges based on the position of a target, leading to inadequate image capture when the target's position changes.
Innovation Solution
An information processing apparatus with a camera, illuminator, and illumination range change unit that adjusts the illumination range and capturing range based on the target's position, using components like mirrors and motors to dynamically change angles and ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the illumination range is fixed, then the device structure is simple, but the image quality deteriorates when the target position changes
Solution Approach 1:
The illumination range is made dynamically adjustable based on the detected target position. The system changes the illumination range from a fixed state to a variable state that adapts to different target positions, ensuring consistent image quality whether the target is close or far away.
Solution Approach 2:
The illumination range parameter is changed according to the target position. When the target is at a different distance, the system modifies the illumination range parameter to optimize lighting conditions, thereby maintaining image quality across various shooting scenarios.
2Manufacturing precision
If the illumination range is widened to cover various positions, then the image quality is maintained, but the illumination intensity decreases
Solution Approach 1:
The system dynamically adjusts two parameters: illumination range and illumination intensity. When the target position indicates a need for wider coverage, the illumination range is expanded while the illumination intensity is simultaneously increased to compensate for the diluted light distribution, thereby maintaining image quality.
Solution Approach 2:
The system uses feedback from target position detection to adjust illumination parameters. Based on the detected target position, the system determines the appropriate illumination range and intensity combination, creating a closed-loop control system that optimizes illumination conditions.
3Manufacturing precision
If the illumination range is adjusted based on target position, then the image quality is improved, but the device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it detects the target position, determines the appropriate illumination range based on that position, and controls the illumination intensity. By consolidating these functions into a single control unit, the system achieves sophisticated illumination control without proportionally increasing device complexity.

AI summary
An information processing apparatus includes: a camera that captures a target; an illuminator that applies illumination light in response to capturing is performed by the camera; and an illumination range change unit that changes an illumination range of the illuminator based on a position of the target. According to the information processing apparatus, the target can be properly illuminated with the illumination light based on the position of the target, and it is thus possible to acquire the image of the target, more properly, even when the position of the target in the capturing is changed, for example.
