Electronic Equipment Display Timing Synchronization for Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic equipment, the placement of a camera module opposite to the display surface leads to degraded image quality due to display luminance effects, and reducing pixel density or display quality to mitigate this issue results in discomfort for the user.
Innovation Solution
A control section synchronizes the display timing with the imaging timing, setting lower frequencies, frame rates, and pixel densities for the display section when the camera module is active, and adjusts luminance values and pixel densities in overlapping regions to minimize the impact of display luminance on image capture.

1Area of stationary object
If the camera module is disposed opposite to the display surface, then the bezel width can be reduced, but the image quality degrades due to display luminance effects
Solution Approach 1:
The display section performs display operations periodically with alternating display periods and non-display periods. During imaging operations, the display section enters a non-display period to prevent display luminance from degrading image quality, while still maintaining periodic display functionality for user interaction.
Solution Approach 2:
The control section determines in advance whether an imaging operation is being performed and proactively controls the display section to enter a non-display state before imaging begins, preventing display luminance from affecting image quality from the outset.
2Measurement precision
If the pixel density of the display region is reduced to mitigate display luminance effects, then image quality improves, but display quality decreases causing user discomfort
Solution Approach 1:
The display section maintains its original pixel density and displays content normally during display periods, providing excellent display quality. During imaging periods, it temporarily suspends display operations rather than reducing pixel density, thus avoiding display quality degradation while still preventing luminance interference with imaging.
3Productivity
If the display section operates at higher frame rates, then display quality improves, but image quality degrades due to increased display luminance during imaging
Solution Approach 1:
The control section dynamically adjusts the display frame rate based on operational mode: during imaging operations, it reduces the frame rate or suspends display temporarily to minimize luminance interference; during normal display operations, it maintains higher frame rates for smooth visual output. This periodic adjustment resolves the contradiction between display smoothness and imaging quality.
