Focus Bracket Display Area Orientation for Image Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing focus bracket photographing techniques struggle to effectively compare and select the appropriate image due to small differences between images, making it difficult for users to identify the best-focused image.
Innovation Solution
An image capturing apparatus is designed with a bracket photographing unit, selection unit, and display unit that adjusts display areas based on focus detection areas, evaluation values, and defocus amounts to facilitate easy comparison and selection of the best-focused image.

Engineering Contradiction Analysis
1Measurement precision
If focus bracket photographing is performed sequentially while changing focal position, then multiple images with different focus positions are obtained, but the differences between images are too small and difficult to recognize
Solution Approach 1:
The display screen is divided into multiple display areas, each showing a cropped region around the focus detection area. This segmentation allows users to compare focus differences across multiple images by viewing only the relevant portions side-by-side, making subtle focus differences more recognizable without requiring full-image comparison.
Solution Approach 2:
The patent applies local quality by displaying cropped images centered on the focus detection area rather than showing complete images. This local view concentrates visual attention on the critical region where focus differences occur, enhancing the ability to detect subtle focus variations in that specific area.
2Ease of operation
If multiple images are displayed in thumbnails for selection, then images can be easily selected by user, but appropriate image selection becomes inefficient when differences are too small
Solution Approach 1:
The patent transitions from displaying multiple complete thumbnails to showing cropped regions within a unified display framework. By dimensionally reorganizing how images are presented—focusing on specific regions rather than complete thumbnails—it enables more efficient comparison while maintaining ease of selection through the structured display layout.

AI summary
In an image capturing apparatus that sequentially photographs a plurality of images by changing a focus position of a lens unit by a predetermined amount, a display area is selected according to a ratio of a vertical line component to a horizontal line component of a main subject for each of the plurality of images photographed by the image capturing apparatus. A display unit displays a plurality of display areas corresponding to the focus detection area selected by the selection unit, by arranging the plurality of display areas side by side.
