Moving Image Overlay with Split Update Rates for Readable Object Labels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ultrasonic endoscopy, displaying anatomical regions in a moving image is challenging due to poor visibility of moving text and lack of user-friendly display options that do not interfere with operation.
Innovation Solution
A moving image processing apparatus that superimposes position and type information of detected objects on a moving image with different update frequencies, ensuring high visibility by stabilizing the display of type information relative to the position information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text is displayed moving with the object in a moving image, then the text remains associated with the object, but the text becomes difficult to identify at a glance due to large movement
Solution Approach 1:
The patent segments the text display into two distinct components: position information that moves with the object at full speed, and type information that moves at a reduced update frequency. This segmentation allows each component to optimize its movement characteristics - position information provides real-time tracking while type information maintains readability by updating less frequently, thus resolving the contradiction between object association and readability.
2Ease of operation
If text is displayed in response to user input for hiding/showing, then user control is provided, but the display cannot be controlled when the user operates the scope with both hands
Solution Approach 1:
The patent implements self-service by making the display of anatomical region information automatically responsive to scope operations without requiring additional user input. The system detects scope operation states and automatically adjusts the display accordingly, eliminating the need for separate control inputs and enabling operation control even when both hands are occupied with the scope.
3Measurement precision
If position information is updated every frame, then the position tracking is accurate, but the type information display becomes unstable
Solution Approach 1:
The patent applies segmentation by separating the update frequencies of position information and type information. Position information is updated every frame to maintain accurate real-time tracking, while type information is updated at a lower frequency to ensure display stability. This differential update strategy resolves the contradiction between tracking precision and display stability.

AI summary
The present disclosure allows information on an object included in a moving image to be superimposed on the moving image and displayed with high visibility. Position information and type information of an object included in frame images of an acquired moving image are acquired, a first display position at which the position information is to be displayed and a second display position at which the type information is to be displayed are determined, the sequentially acquired frame images are sequentially displayed on a display, the position information and the type information are displayed so as to be superimposed on each of the displayed frame images at the first display position and the second display position, the first display position is updated with a first update frequency, and the second display position is updated with a second update frequency lower than the first update frequency.
