Thumbnail Crop Display Layout for Preset Composition Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network cameras with crop functions display thumbnail images that are too small, reducing visibility when the crop function is turned on, making it difficult for users to confirm the composition after executing presets.
Innovation Solution
A display control apparatus that determines a cut-out region based on the size of the display region and the angle of view region, and performs display processing to enlarge the thumbnail image within this region, ensuring that the crop region is clearly visible.

Engineering Contradiction Analysis
1Area of stationary object
If thumbnail images are reduced in size when displayed, then more thumbnails can be displayed on the screen, but the visibility of the crop region becomes too small
Solution Approach 1:
The thumbnail image is divided into two distinct regions: a first region displaying the crop region (enlarged view) and a second region displaying the entire frame (smaller view). This segmentation allows the crop region to be displayed with sufficient detail while maintaining the ability to see the full context in the second region, thereby resolving the contradiction between displaying more thumbnails and maintaining visibility of the crop region.
2Productivity
If a crop region is set in a state in which the crop function is turned on, then the camera outputs only the cropped image, but the user cannot confirm the composition after executing presets
Solution Approach 1:
The display merges two different views into a single thumbnail image: the crop region (showing the actual output when preset is executed) and the entire frame (showing the full scene context). This merging allows users to quickly understand both the cropped composition and the original scene without manually adjusting or switching between different display modes, thus maintaining ease of operation while improving composition confirmation.

AI summary
A display control apparatus is configured to acquire at least a first image among one or more images acquired by one or more image capturing apparatuses, and determine a cut-out region from the first image including a second angle of view region, based on at least one of a size of a display region of a thumbnail image on a display screen and a size of the second angle of view region that is smaller than a first angle of view region that is a region of an angle of view of the first image. The display control apparatus performs display processing to display an image which is cut out from the first image and which corresponds to the determined cut-out region.
