Capsule Endoscope Image Display Selective Frame Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display apparatuses for capsule endoscopes display images of high similarity uniformly, leading to difficulties in observing regions of interest, such as bleeding sites, at fast rates, which can hinder the examination process.
Innovation Solution
An image display apparatus that includes an image identifying unit to extract and display images of a desired region of interest at a slower frame rate than other regions, allowing for selective control of display rates based on region identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display frame rate is increased to shorten observation time, then productivity is improved, but the ability to observe regions of interest deteriorates
Solution Approach 1:
The patent segments the image sequence into two categories: regions of interest (identified by specific features such as bleeding sites) and non-interest regions. Different frame rates are applied to each segment, allowing fast playback for non-interest areas while maintaining slow playback for critical regions, thus resolving the contradiction between overall observation speed and detailed examination quality.
Solution Approach 2:
The patent implements local quality control by assigning different display frame rates to different spatial regions within the image sequence. Regions containing medically significant features are displayed at slower frame rates for careful examination, while other regions are displayed at faster rates, creating a localized quality differentiation that satisfies both speed and accuracy requirements.
2Loss of time
If the display frame rate is uniformly increased for all images, then loss of time is reduced, but measurement precision of region of interest deteriorates
Solution Approach 1:
The patent performs preliminary identification of regions of interest before playback by analyzing image features (such as detecting bleeding sites through color analysis or other medical criteria). This preliminary action allows the system to pre-mark critical regions and apply appropriate frame rates during playback, ensuring that time is not lost in identifying important areas during fast playback.
Solution Approach 2:
The system uses feedback from image analysis to dynamically control display frame rates. By continuously monitoring identified regions of interest and comparing them against playback speed settings, the system adjusts frame rates to maintain optimal observation conditions for critical areas while maximizing overall playback efficiency.

AI summary
An image display apparatus that can shorten time for observing a series of images of an interior of a subject without hampering observation of a desired region of interest is provided. The image display apparatus according to the present invention is an image display apparatus for displaying the series of images of the interior of the subject picked up at time series, including an image extracting unit 15a that extracts images each having a feature of a desired region in the interior of the subject and that identifies the extracted images as images of the desired region among the series of images, and a frame rate controller 15b that sets a display frame rate for the identified images of the desired region to be different from a display frame rate for images of regions other than the desired region.
