Cross-Device Brightness Matching With Masked Display Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot intuitively perceive the brightness adjustment effect when adjusting display brightness across devices or displays, leading to low efficiency and poor adjustment effects.
Innovation Solution
A brightness adjustment system and method that uses a first electronic device to display two masked areas on its screen, where the masked areas maintain the same brightness or perceived brightness as the corresponding areas on a second electronic device, allowing users to intuitively adjust the second device's brightness based on the displayed effects.

Engineering Contradiction Analysis
1Ease of operation
If brightness is adjusted across devices or displays using conventional methods, then brightness adjustment can be performed, but the user cannot intuitively perceive the brightness adjustment effect, resulting in low adjustment efficiency and poor adjustment effect
Solution Approach 1:
The patent creates a virtual copy of the second display's brightness characteristics on the first display. By displaying a second area with brightness or perceived brightness matching the second display, and covering it with a mask whose transparency corresponds to the brightness adjustment, the system provides a visual copy of the adjustment effect on the controlling display, enabling intuitive perception without directly viewing the second display
Solution Approach 2:
The patent introduces a mask as an intermediary element between the user and the brightness adjustment effect. The mask's transparency is adjusted to correspond to the brightness level of the second display, and when placed over the second area on the first display, it mediates the visual perception of brightness, allowing the user to intuitively perceive the adjustment effect on the first display while actually controlling the second display

AI summary
A first electronic device is configured to display a first area and a second area on a first display of the first electronic device in response to a first operation, where the first operation indicates to start adjusting display brightness of a second display of a second electronic device. The first area and the second area each are covered with a mask, and display brightness of the second area after covering with the mask is equal to the display brightness of the second display, or perceived brightness of the second area after covering with the mask is equal to perceived brightness of the second display.
