Display Control Circuit for Image-Displaying Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-displaying devices face delays in displaying images due to varying times required to generate display subjects, leading to unnecessary delays in displaying subjects that can be generated early, as existing techniques apply a common phase difference to all frames regardless of the type of subject being displayed.
Innovation Solution
A display control circuit that allows for the recording and sequential retrieval of information data before display, enabling immediate display without standby time, and adjusts line display times in the information display region to minimize delays, synchronizing with the progress of image data generation in the subject image display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a common phase difference ΔT is applied to all frames to ensure reading does not precede writing, then data integrity is maintained, but unnecessary delays occur in displaying subjects that can be generated early
Solution Approach 1:
The display screen is divided into two distinct regions: a subject image display region for displaying captured images and an information display region for displaying information such as capture conditions. Each region is assigned different line display times optimized for its specific content requirements, allowing the information region to use shorter line display times without affecting image quality.
Solution Approach 2:
Different line display times are applied to different regions of the display screen. The subject image display region uses longer line display times to maintain image quality, while the information display region uses shorter line display times to reduce delays and enable faster display of information that does not require the same quality constraints.
2Reliability
If the line display time is extended to accommodate the longest image data generation time, then all display subjects can be displayed without delay, but the overall display speed is reduced
Solution Approach 1:
The display control circuit segments the display refresh process by region, allowing independent optimization of line display times for different areas. This enables the information display region to refresh faster without being constrained by the longer processing times required for image data in the subject image display region.
Solution Approach 2:
The system dynamically adjusts line display times based on the type of content being displayed in each region. The display control circuit selectively applies different line display time values to different regions, optimizing the balance between display speed and quality for each specific content type.

AI summary
An image-displaying device includes an image data generation means, an information data acquisition means, and a display control means. The information data acquisition means is configured to acquire information data for causing predetermined information to be displayed on an information display region. The display control means is configured to control a display means to display an image of a subject in a subject image display region of the display means according to image data generated by processing for generating the image data, and to display the predetermined information in the information display region of the display means according to the information data. The display control means is configured to control the display means so that a predetermined unit display time taken to refresh a display in each of predetermined units in the information display region is shorter than the predetermined unit display time in the subject image display region.
