Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device photographing methods using fill-in light, either through liquid crystal displays or flashlights, result in poor image display effects and user experience due to uncomfortable light flashes or obvious shadows.
Innovation Solution
An electronic device with a flexible display screen that adjusts its luminance and folding angle based on pixel coordinates of the photographed object, providing targeted fill-in light to improve image quality and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fill-in light is implemented by using a liquid crystal display, then photographing effect is improved, but luminance instantly increases causing light flashes and discomfort to human eyes
Solution Approach 1:
The patent applies the dynamics principle by dynamically adjusting the luminance of the liquid crystal display based on the photographing requirements and ambient conditions. Instead of instantly increasing luminance to maximum, the system gradually adjusts the brightness level to provide fill-in light while avoiding sudden flashes that cause discomfort to human eyes. This dynamic adjustment resolves the contradiction between providing sufficient illumination and preventing harmful light flashes.
2Illumination intensity
If fill-in light is implemented by using a flashlight, then photographing effect is improved, but light is hard causing obvious image shadows
Solution Approach 1:
The patent applies the local quality principle by using different illumination sources for different regions. The liquid crystal display provides soft, diffused fill-in light for areas requiring gentle illumination, while the flashlight provides directed light for areas needing stronger illumination. This regional differentiation of light quality allows the system to provide effective fill-in light while minimizing harsh shadows, as the liquid crystal display's diffused light fills in shadow areas created by the flashlight.
3Illumination intensity
If luminance of liquid crystal display is instantly increased, then fill-in light is provided, but user experience is poor
Solution Approach 1:
The patent applies the preliminary action principle by pre-adjusting the liquid crystal display luminance to appropriate levels before photographing begins. The system detects ambient light conditions and pre-configures the display brightness to provide necessary fill-in light without requiring sudden, jarring increases in luminance during the photographing process. This preliminary preparation ensures both adequate illumination and comfortable user experience from the start.

AI summary
An electronic device photographing method and an apparatus are provided. The electronic device includes a camera module, a main display screen, and at least one flexible display screen. The method includes: after the electronic device enters a photographing screen, determining a folding angle of the flexible display screen based on a pixel coordinate parameter of a photographed object on the photographing screen; and/or determining target luminance of a display screen; and when detecting that a photographing button is pressed, adjusting luminance of the display screen to the determined target luminance. In this way, when the electronic device is used to take an image, fill-in light can be implemented for the photographed photo by improving target luminance of the display screen based on the pixel coordinate parameter of the photographed object on the photographing screen, so as to improve an image photographing effect.
