LED Array Illumination for Digital Image Capturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for improving lighting in video and image capturing environments, such as wide dynamic range (WDR) and external accessories, either require manual adjustment or sacrifice elegance and intelligence, and are ineffective in low-light conditions.
Innovation Solution
A system comprising a processor, memory, digital camera, and an array of LEDs surrounding a display screen, where the processor retrieves preferred image quality attributes, adjusts LED settings for color and brightness, and compares these attributes to captured image attributes to optimize illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If manual adjustment of lighting is used, then lighting can be adjusted to improve image quality, but it requires time, know-how and an environment where lighting can be easily altered
Solution Approach 1:
The system uses an array of LEDs surrounding the display screen that automatically adjust their brightness and color temperature based on ambient light conditions detected by the processor, eliminating the need for manual intervention. The processor continuously monitors lighting conditions and autonomously optimizes LED settings to provide ideal illumination for image capturing.
2Illumination intensity
If accessories for phones are used to provide improved front facing light, then lighting is improved, but elegance and intelligence are sacrificed
Solution Approach 1:
The lighting system is integrated directly into the device structure with an array of LEDs embedded around the display screen. This merging of lighting functionality into the device itself eliminates the need for external accessories, maintaining elegance while providing intelligent, automated lighting control through the processor.
3Manufacturing precision
If WDR is used to capture multiple exposures, then optimized images are achieved, but it requires light and dark contrast to function properly
Solution Approach 1:
Instead of capturing multiple exposures and merging them post-processing, the system preemptively adjusts the LED illumination settings before image capture to ensure optimal lighting conditions. The processor detects ambient light conditions and pre-configures the LED array to provide the ideal balance of brightness and color temperature, eliminating the need for WDR processing and enabling consistent image quality across all lighting environments.

AI summary
An approach is provided that uses an array of LEDs to illuminate for digital image capturing. A system that includes a processor, a memory accessible by the processor, a digital camera accessible by the processor, a display screen accessible by the processor, and an array of a plurality of LEDs surrounding the display screen, where the array of LEDs is also accessible by the processor. Preferred image quality attributes are retrieved. Then a setting of a set of LEDs is made to a lighting attribute, such as color or brightness. Afterwards, the an image of a subject illuminated by the plurality of LEDs is captured and attributes of this image are compared to the preferred image quality attributes. Based on the comparison, the approach then adjusts the attributes of the set of LEDs.
