Image Processing Device for Clear Zoomed Region Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images zoomed in on imaging devices often appear unclear if the specific region is out of focus, leading to blurry displays, especially when the zoomed image exceeds the resolution of the original capture.
Innovation Solution
An image processing device that captures multiple images with different in-focus positions and selects the one with the sharpest focus for the designated region, blending these images to create a clear in-focus region for display, ensuring that the zoomed image remains clear and recognizable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specific region of an image is zoomed in for detailed display, then the displayed region can be viewed in greater detail, but the image appears unclear if the zoomed region is out of focus
Solution Approach 1:
The system captures multiple images at different focus positions before the zoom operation is performed. By pre-capturing images with varying focus depths, the system ensures that when a user zooms into any region, a clearly focused image is already available for display, eliminating the blur problem that would otherwise occur with digital zooming.
Solution Approach 2:
The system changes the focus parameter (focus position) across multiple captured images. By varying the focus depth parameter during image capture, the system creates a set of images where different regions are in focus, allowing the display control to select the appropriate focused image for the designated zoom region.
2Measurement precision
If multiple images with different in-focus positions are captured to ensure clear zoom display, then image clarity can be maintained, but the device complexity increases
Solution Approach 1:
The system uses the camera's existing autofocus mechanism to automatically capture images at different focus positions without requiring manual intervention. The image processing unit automatically analyzes the captured images to identify in-focus regions and selects the appropriate image for display, making the system self-sufficient and reducing operational complexity.
Solution Approach 2:
The system replaces complex mechanical zoom mechanisms with a computational approach. Instead of using optical zoom lenses that would require precise mechanical adjustment, the system uses digital image processing to select and display the appropriate focused region from multiple captured images, substituting mechanical complexity with computational simplicity.

AI summary
An image processing device according to the present disclosure includes: a locating unit which locates a first in-focus region of each of plural images which are obtained by capturing a same subject and have different in-focus positions; and a display unit which displays a first image among the plural images, wherein when a certain position is designated on the first image displayed by the display unit, at least a second image having the first in-focus region which includes the certain position is selected from among the plural images, and the selected second image is displayed on the display unit.
