Solution Overview

Problem

Existing video signal monitors face difficulties in precisely identifying corresponding positions across different image formats, such as picture, waveform, and vector displays, due to the distinct representations of video signals, making it challenging to align and adjust images accurately.

Innovation Solution

A method and apparatus for generating a marker that facilitates the alignment of corresponding positions across multiple images associated with a video signal, utilizing a computer-readable storage medium and a display control/additional image generator circuit to combine and display markers on picture, vector, and waveform images, allowing precise identification of matching points through cursor manipulation and image processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple image formats (picture, waveform, vector) are displayed simultaneously to provide comprehensive video signal information, then the completeness of information is improved, but the difficulty of identifying corresponding positions across different formats increases

Engineering Contradiction:
Improvecompleteness of video signal informationVSAvoiddifficulty of identifying corresponding positions
Core Design Contradiction:
Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces markers as intermediary elements that are superimposed on all three display formats (picture, waveform, vector). These markers serve as a common reference system that mediates between the different formats, enabling users to identify corresponding positions across formats by tracking the marker's position in each display type.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The marker system performs multiple functions simultaneously: it provides position reference across different formats, indicates signal characteristics, and enables correlation between picture, waveform, and vector displays. This multi-functional approach resolves the contradiction by making a single element serve all identification needs across formats.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If different display formats (picture, waveform, vector) are used to represent the same video signal, then the versatility of analysis is improved, but the ease of associating images across formats deteriorates

Engineering Contradiction:
Improveversatility of video signal analysisVSAvoidease of associating images across formats
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Markers act as a universal intermediary that appears in all display formats with consistent positional and characteristic information. This allows users to easily associate images across formats by following the marker's representation in each format, maintaining ease of operation while preserving versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes visual characteristics of markers (such as color, brightness, or pattern changes) to encode information about the video signal. These visual changes are reflected consistently across all display formats, enabling users to associate images by observing the marker's visual properties rather than relying on complex coordinate transformations.

Inventive Principle:
Principle #32Color changes

3Ease of operation

If time-based correlation is used to associate picture and waveform displays, then the simplicity of association is improved, but the accuracy of position identification deteriorates

Engineering Contradiction:
Improvesimplicity of associationVSAvoidprecision of position identification
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The marker serves as a precise intermediary reference that goes beyond time-based correlation. While time synchronization provides a rough association, the marker's explicit positional representation in each format enables precise identification of corresponding locations, combining the simplicity of time-based methods with the precision of spatial reference.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A marker generating method is provided for facilitating the finding of positions which correspond to one another among a plurality of images associated with a video signal. A position within an image (800) associated with a video signal is selected, with a cursor (802, 804) to display a marker (812, 822-826) at a position corresponding to the selected position, in a different image (810, 820) associated with the video signal.
