Display Control Device for Simultaneous Full and Partial View Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In imaging devices, users face difficulties in adjusting composition while focusing due to the inability to simultaneously view the entire imaging range and a partial region, as existing techniques only allow for the enlargement of a part of the object, obscuring the overall framing.
Innovation Solution
A display control device and method that outputs a first image representing the entire angle of view by pixel-thinning and a second image representing a partial region in high detail, allowing both to be displayed simultaneously on the same screen, enabling users to adjust focus and composition effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a part of the object is enlarged and displayed on the full screen, then the visibility of the partial region is improved, but the entire imaging range cannot be grasped
Solution Approach 1:
The display screen is segmented into multiple display regions: a first display region showing the entire imaging range and a second display region showing an enlarged view of a partial region. This segmentation allows users to simultaneously view both the overall composition and detailed focus areas without losing information about either.
Solution Approach 2:
The patent transitions from a single full-screen display mode to a multi-region display mode by utilizing different spatial dimensions on the display screen. The first image occupies a first display region while the second image occupies a second display region, effectively using screen space in a multi-dimensional layout to present multiple views simultaneously.
2Measurement precision
If the display unit enlarges and displays a part of the object on a full screen, then the focus checking ability is improved, but the composition adjustment capability deteriorates
Solution Approach 1:
The display is segmented into functional regions: one region dedicated to showing the entire imaging range for composition adjustment, and another region dedicated to showing the enlarged partial region for focus checking. This functional segmentation enables users to perform both composition adjustment and focus checking simultaneously without compromising either capability.
3Loss of energy
If pixel-thinning is applied for the entire angle of view, then the data transmission load is reduced, but the image quality for the entire range is degraded
Solution Approach 1:
Different pixel sampling strategies are applied to different regions: pixel-thinning is applied to the entire angle of view for the first image to reduce data load, while all pixels are utilized for the partial region in the second image to maintain high image quality. This local quality differentiation optimizes both data efficiency and image quality where needed.
Solution Approach 2:
The patent changes the pixel sampling parameter differently for different regions: for the first image covering the entire angle of view, pixel-thinning reduces the pixel count and data transmission load; for the second image covering the partial region, full pixel utilization maintains high resolution. This parameter change strategy balances data efficiency and quality requirements.

AI summary
A display control device includes a display control unit configured to control a display unit to output a first image based on a first imaging signal and a second image based on a second imaging signal, the first imaging signal and the second imaging signal being output from an imaging element that outputs the first imaging signal by pixel-thinning for an entire angle of view and outputs the second imaging signal in all of pixels for a partial region in the entire angle of view.
