External Illumination Control for Camera Imaging Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current photographing devices face limitations in improving imaging quality in poor lighting conditions, necessitating the development of alternative methods to enhance the photographing effect.
Innovation Solution
The method involves determining a to-be-adjusted region in a photograph framing image, analyzing light source modulation information to identify external light sources that need illumination control, and sending instruction information to these sources for optical adjustments to improve imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flash lamp or light-compensating lamp is built in to improve photographing effect in poor light, then imaging quality is improved, but device complexity increases
Solution Approach 1:
The patent introduces an illumination control apparatus as an intermediary device that communicates with external light sources via wireless communication. This mediator coordinates the illumination of external light sources based on imaging requirements, achieving improved imaging quality without integrating complex lighting components into the photographing device itself
Solution Approach 2:
The patent separates the illumination control function from the photographing device. The illumination control apparatus independently determines to-be-adjusted regions and controls external light sources, dividing the system into distinct functional modules that can operate independently, thereby reducing overall device complexity
2Manufacturing precision
If self adjustment capability is used to improve photographing effect, then imaging quality is improved, but the level of improvement is limited
Solution Approach 1:
The patent implements a feedback mechanism where the illumination control apparatus receives imaging rays from the photographing device, analyzes the to-be-adjusted regions, and sends illumination control instructions to external light sources. This closed-loop feedback system enables adaptive illumination adjustment that goes beyond basic self-adjustment capabilities
Solution Approach 2:
The illumination control apparatus serves multiple functions: it determines to-be-adjusted regions, identifies appropriate external light sources, generates illumination control instructions, and coordinates with multiple light sources simultaneously. This multi-functional approach significantly enhances the level of improvement beyond simple self-adjustment

AI summary
Illumination control methods and apparatuses and various devices having a photographing function are disclosed. An example illumination control method comprises: determining a to-be-adjusted region that needs optical parameter adjustment in a photograph framing image; determining, according to light source modulation information carried in received imaging rays corresponding to the to-be-adjusted region, at least one external light source that needs to be illumination controlled; determining illumination control instruction information of the to-be-adjusted region; and sending the illumination control instruction information to the at least one external light source determined, so as to instruct the at least one external light source to perform at least one optical adjustment according to the illumination control instruction information. Imaging quality and photographing effect can be improved thereby.
