Image Brightness Correction via LED Temperature Characteristics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies require driving and controlling illumination light sources to adjust image brightness, which is inefficient and can result in unstable electric current stabilization and inaccurate subject brightness in photographs.
Innovation Solution
An information processing apparatus and method that acquires images and illumination light source temperatures, using a correction unit to adjust image brightness based on temperature characteristics without driving the light source, thereby stabilizing the electric current and maintaining accurate subject brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the illumination light source is driven and controlled to adjust image brightness, then the brightness can be adjusted, but the electric current stabilization time increases and the system becomes more complex
Solution Approach 1:
The patent introduces a correction unit as an intermediary that processes the captured image to adjust brightness based on temperature characteristics, rather than directly controlling the illumination light source. This mediator approach allows brightness correction without affecting the light source's electric current stabilization
Solution Approach 2:
The patent replaces the mechanical/electrical control system (driving and controlling the illumination light source) with an image processing system (correction unit that adjusts brightness through software algorithms based on temperature characteristics)
2Illumination intensity
If the illumination light source is driven and controlled to adjust image brightness, then the brightness can be adjusted, but the device complexity increases
Solution Approach 1:
The correction unit serves as an intermediary layer between the image capture and the final output, handling brightness adjustment through image processing rather than hardware control, thereby simplifying the overall system architecture
Solution Approach 2:
The patent creates a virtual model of the illumination characteristics through temperature characteristics data, using this copied information to guide brightness correction without needing complex real-time hardware control systems
