Dynamic Zoom Center for Digital Pathology Image Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for digital pathological image analysis require multiple steps and limited zoom functionality, making it inefficient to observe specific regions, especially around corners, and prone to missing important details due to restricted display range adjustments.
Innovation Solution
An information processing apparatus that allows users to change zoom magnification and display range by selecting positions on the image, using a cursor pointer, and switching between modes to center-fixate or center-variability, enabling seamless zoom-in and zoom-out operations without losing focus on critical areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If zoom-in operation is performed with center fixation, then image detail observation is improved, but the desired region may go outside the screen and operation efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the zoom center position variable rather than fixed. The system dynamically adjusts the zoom center based on the cursor position, allowing the display range to automatically follow the user's focus point. This resolves the contradiction by enabling detailed observation of any region without risking that the region will go outside the screen, as the screen center adapts to the user's selected position.
Solution Approach 2:
The patent introduces a new dimension of control by adding cursor position as a variable parameter. Instead of only controlling zoom magnification, the system now controls both zoom magnification and zoom center position independently. This additional degree of freedom allows the display range to be precisely positioned around the cursor, preventing the desired region from going outside the screen while maintaining detailed observation capability.
2Measurement precision
If multiple operation steps are required for zoom-in, then image detail observation is improved, but operation complexity increases and efficiency deteriorates
Solution Approach 1:
The patent merges the shift operation and zoom-in operation into a single integrated action. By combining these two previously separate operations into one unified zoom function that automatically adjusts both position and magnification, the system reduces operational complexity while maintaining the ability to observe image details. The user only needs to specify a position and zoom level, and the system handles both positioning and scaling simultaneously.
Solution Approach 2:
The system performs preliminary positioning automatically before the zoom operation is completed. When the user initiates a zoom-in operation, the display range is pre-positioned around the cursor location, ensuring the desired region remains centered throughout the zoom process. This preliminary action eliminates the need for manual shifting steps that would otherwise be required after zooming.
3Stability of the object's composition
If display range shifting is limited to cursor movable range, then screen boundary constraints are maintained, but operation efficiency deteriorates when further display range is needed
Solution Approach 1:
The patent applies dynamics by making the display range boundaries adaptive rather than fixed to screen edges. The display range can dynamically extend beyond the traditional cursor movable limits by automatically adjusting the zoom center position. This allows the system to maintain stable screen composition while enabling efficient access to broader display ranges through intelligent repositioning of the visible area.

AI summary
In one example embodiment, an information processing apparatus displays a first image associated with an observation target object. In this example embodiment, the first image has a first zoom magnification and a first display range which has a first center position. In one example embodiment, the information processing apparatus enables a user to change the first zoom magnification by selecting a first position of the displayed first image. In response to the first position being selected, the information processing apparatus displays a second image associated with the observation target image. In this example embodiment, the second image has a second zoom magnification which is different from the first zoom magnification. The second image also has a second display range which has a second center position which is different from the first center position. In this example embodiment, the second center position corresponds to the selected position.
