Solution Overview

Problem

Existing techniques for observing three-dimensionally cultured cells and tissue sections often fail to clearly display all objects present, as two-dimensional and three-dimensional observations are not effectively integrated, leading to unclear visualization of specimens.

Innovation Solution

An image display method and device that obtain multiple two-dimensional images at different focus positions, generate three-dimensional image data, and integrate selected two-dimensional images with three-dimensional images to provide a comprehensive, integrated image display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single two-dimensional image is obtained by focusing on one position, then the image at that specific focus position is clear, but other objects at different depths remain unclear

Engineering Contradiction:
Improveimage clarity at focus positionVSAvoidvisibility of objects at different depths
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The specimen is divided into multiple depth layers, with each layer captured as a separate two-dimensional image at its optimal focus position. This segmentation allows each object regardless of depth to be clearly imaged in its own layer, resolving the contradiction between single-point focus clarity and multi-depth visibility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution transitions from two-dimensional imaging to three-dimensional imaging by adding the depth dimension. Multiple two-dimensional images captured at different focus positions are integrated to form a three-dimensional image, enabling simultaneous observation of objects at various depths while maintaining clarity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If only three-dimensional image data is displayed, then comprehensive spatial information is provided, but detailed surface information and texture are lost

Engineering Contradiction:
Improvespatial information completenessVSAvoidsurface detail and texture clarity
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent merges three-dimensional image data with selected two-dimensional images to create an integrated image. The three-dimensional component provides comprehensive spatial information and depth context, while the two-dimensional component preserves surface detail and texture, thus resolving the contradiction between spatial completeness and surface detail

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If multiple two-dimensional images at different focus positions are captured, then all objects in three-dimensional space can be observed, but the complexity of image processing and integration increases

Engineering Contradiction:
Improvecompleteness of object observationVSAvoidimage processing and integration complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Instead of processing all captured two-dimensional images, the system extracts and selects only the most appropriate images for integration. This extraction approach reduces processing complexity while maintaining completeness of object observation, as only relevant images need to be integrated rather than all captured images

Inventive Principle:
Principle #2Taking out (Extraction)
