Display Control Apparatus for Simultaneous Full and Zoomed Image Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic zoom display functions in imaging systems make it difficult to simultaneously view the entire image and check focusing accuracy in high-resolution images, as users must frequently switch between zoomed and full-image views, limiting effective focus adjustment.
Innovation Solution
A display control apparatus that acquires input images, generates zoom images, and determines the display mode based on focus information, allowing for seamless switching between displaying the input image, zoom image, or both, to facilitate accurate focus adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a zoom image is displayed to perform fine adjustment of focus, then focusing precision is improved, but the ability to view the entire image is lost
Solution Approach 1:
The display screen is segmented into multiple regions: a main display area showing the entire input image and a sub-screen area showing the zoomed image. This allows users to simultaneously view both the overall image composition and the detailed focus area without losing context of the entire scene.
Solution Approach 2:
The zoomed image is displayed in a separate spatial dimension (sub-screen) rather than replacing the main display. This dimensional separation allows concurrent viewing of both full-image and zoomed views, resolving the trade-off between focus precision and overall image awareness.
2Loss of information
If the entire input image is displayed to check overall composition, then image composition visibility is improved, but focus adjustment precision deteriorates
Solution Approach 1:
The display is segmented into a main area for overall image composition and a sub-screen for detailed focus checking. Users can monitor the entire image composition in the main display while simultaneously assessing focus accuracy in the zoomed sub-screen without needing to switch between views.
Solution Approach 2:
By displaying the zoomed image in a separate sub-screen dimension rather than full-screen replacement, users gain the ability to view both composition and focus detail concurrently, eliminating the need to toggle between display modes during focus adjustment.
3Measurement precision
If users switch between zoom display and full image display to check focus, then focus checking capability is improved, but operational complexity increases
Solution Approach 1:
The full-image display and zoomed focus display are merged into a single unified interface with the main image occupying the primary display area and the zoomed image appearing as an overlaid sub-screen. This combination eliminates the need to switch between separate display modes, allowing continuous monitoring of both overall composition and focus accuracy simultaneously.

AI summary
A display control apparatus, includes: at least one processor and/or at least one circuit to perform the operations of the following units: an input unit configured to acquire an input image which is an image captured by an imaging apparatus; a generation unit configured to generate at least one zoom image which is an image generated by magnifying a part of the regions of the input image; an acquisition unit configured to acquire focus information of the imaging apparatus; and a determination unit configured to determine which one of (1) the input image, (2) the zoom image and (3) both of the input image and the zoom image are to be displayed as a display image on a display unit on the basis of the focus information.
