Dynamic Image Display Device Frame Rate Interpolation

Solution Overview

Problem

Existing methods for comparing dynamic images at different frame rates are limited in accuracy, particularly when the frame rate of one image is lower, which hampers the precision of case examinations.

Innovation Solution

A dynamic image display device and method that acquire a first dynamic image at a higher frame rate and a second dynamic image at a lower frame rate, generate interpolation images between frames of the second dynamic image to increase its frame rate, and display both images in a comparable manner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If frames of one dynamic image are thinned out to adjust frame rates, then the frame rate of the dynamic image is reduced to match the lower frame rate, but the accuracy of comparison between dynamic images is not improved and the accuracy of case examination deteriorates

Engineering Contradiction:

Improveframe rate adjustmentVSAvoidcomparison accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by generating interpolation images in advance before comparison. The hardware processor creates intermediate frames between existing frames of the second dynamic image, preparing enhanced data that maintains the original high frame rate characteristics while enabling compatibility with the lower frame rate image for accurate comparison.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Interpolation images serve as intermediaries between the first dynamic image at higher frame rate and the second dynamic image at lower frame rate. These generated intermediate frames act as a bridge, allowing the system to compare images at different frame rates without directly thinning out frames, thereby maintaining comparison accuracy while achieving frame rate adaptation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If the frame rate of each dynamic image is improved, then the quality of individual dynamic images is enhanced, but the accuracy of comparison between dynamic images at low frame rate does not improve

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary actions by generating interpolation images in advance before comparison. The hardware processor creates intermediate frames between existing frames of the second dynamic image, preparing enhanced data that maintains the original high frame rate characteristics while enabling compatibility with the lower frame rate image for accurate comparison.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter of frame rate by generating interpolation images that effectively increase the frame rate of the second dynamic image. This parameter transformation allows the system to work with high frame rate data while maintaining compatibility with lower frame rate images, thereby improving both image quality and comparison accuracy simultaneously.

AI summary

A dynamic image display device includes a hardware processor and a display. The hardware processor acquires a first dynamic image captured at a first frame rate and a second dynamic image captured at a second frame rate lower than the first frame rate, and generates an interpolation image between each frame image of the second dynamic image and increases a frame rate of the second dynamic image. The display that displays the first dynamic image and the second dynamic image that includes the interpolation image in a comparable manner.
