Camera Illumination Device Real-Time Color Temperature Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination devices for photography require preparatory photographing to set the color temperature, leading to time consumption and potential loss of shooting opportunities due to object movement, and cameras face challenges in achieving desired light emission amounts during actual photography.
Innovation Solution
A camera system with an LED light emission unit that progressively changes the color temperature of illumination light in real-time, allowing photographers to select the desired color and light emission pattern through a user-friendly interface, enabling flexible and timely photography.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If preparatory photographing is performed to set the color temperature of the flash, then the color temperature can be accurately set, but photographing takes time and shooting opportunities may be lost
Solution Approach 1:
The camera performs preparatory photographing and flash color temperature setting in advance before the actual shooting moment. The flash color temperature is determined through preparatory imaging and stored for immediate use during actual photographing, eliminating the need for real-time adjustment and thus resolving the time loss issue while maintaining accurate color temperature setting.
2Adaptability or versatility
If the light emission amount of the flash is automatically changed, then the camera can adapt to different conditions, but it becomes difficult for the photographer to achieve the desired light emission amount
Solution Approach 1:
The flash light emission amount is designed to dynamically change according to the distance between the camera and the subject. The control unit automatically adjusts the flash output based on detected distance information, providing adaptive light emission that matches different shooting scenarios while maintaining photographer control through automatic adjustment rather than manual intervention.

AI summary
It is possible to provide a user-friendly camera. Provided is an illumination device for emitting illumination light for photographing by a camera including: a light emission unit which can emit lights of a plurality of different colors and/or a plurality of different light emission amounts as the illumination light; and a light emission control unit which controls the light emission unit so as to continuously emit the illumination light while changing the color and/or the light emission amount as the time elapses, independently of photographing by the camera.
