Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face challenges in maintaining uniform timing between exposure and display during continuous imaging, especially when the user initiates continuous shooting at arbitrary times, leading to potential discrepancies in captured images and user discomfort.
Innovation Solution
A display control device and method that switch between display modes with different vertical resolutions, adjusting display update timing to maintain consistent image display and capture intervals, using techniques like interlacing and progressive methods to manage frame rates and reduce flickering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display update rate is modified in response to continuous shooting start timing, then the display can be optimized for different shooting scenarios, but variation occurs in the time from instruction to start continuous shooting to acquisition of static image or display image
Solution Approach 1:
The system performs preliminary actions by pre-calculating and pre-adjusting display update timing based on the arbitrary start timing of continuous shooting. The control unit determines the display update timing in advance to ensure that the time intervals from shooting start to static image acquisition and from display image acquisition to display remain uniform, preventing timing variations before they occur.
Solution Approach 2:
The system dynamically adjusts the display update rate and timing based on the arbitrary start timing of continuous shooting. The control unit modifies display update timing in real-time to maintain uniform intervals, allowing the display system to adapt flexibly to different shooting scenarios while preserving timing consistency through active control.
2Stability of the object's composition
If exposure timing and display update timing are controlled without considering arbitrary continuous shooting start timing, then timing uniformity can be maintained, but the captured image may differ from user intention
Solution Approach 1:
The control unit uses feedback from the arbitrary start timing of continuous shooting to adjust display update timing. By monitoring when the user initiates continuous shooting and using this information to recalculate and adjust timing parameters, the system ensures that the time intervals align with user expectations while maintaining overall timing uniformity throughout the shooting sequence.
3Manufacturing precision
If the display panel operates at high vertical resolution, then image quality is improved, but power consumption and processing load increase during continuous imaging
Solution Approach 1:
The display panel dynamically switches between first and second display modes with different vertical resolutions based on the shooting scenario. During continuous imaging, the system can switch to the second display mode with lower vertical resolution to reduce power consumption and processing load, while still maintaining adequate image quality for the live view display.
Solution Approach 2:
The system changes the display vertical resolution parameter dynamically based on operational context. By switching between different vertical resolution settings (first and second display modes), the system optimizes the balance between image quality and power consumption during continuous imaging operations.

AI summary
A display control device for controlling a display panel is switchable between a first display mode in which a video is displayed at a first vertical resolution and a second display mode in which a video is displayed at a second vertical resolution that is lower than the first vertical resolution. The display control device comprises at least one memory and at least one processor which function as: a control unit configured, in a first case where a first operation is received in the first display mode, to change to the second display mode after changing a display update timing in the first display mode, and in a second case where a second operation is received in the second display mode, to change the display update timing after changing to the first display mode.
