Endoscope Illumination Continuous Light Emission for Image Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscope techniques degrade image quality by delaying the capture of movement in highlighted images due to the sequential emission of illumination lights, leading to a feeling of strangeness and reduced viewability of specific structures like blood vessels under a mucus membrane.
Innovation Solution
An endoscope apparatus that continuously emits a first light with a wavelength band corresponding to the luminance component and a second light with a wavelength band enabling higher contrast, allowing for synchronized capture of images, thereby reducing the time difference between object and structure movement and improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If illumination lights are emitted sequentially to capture images with different wavelength bands, then image quality with highlighted structures is improved, but time delay in capturing movement occurs
Solution Approach 1:
The illumination device emits multiple lights with different wavelength bands continuously and simultaneously rather than sequentially. This allows images capturing different structures (luminance component and specific structures like blood vessels) to be obtained at the same time, eliminating the time delay that occurs when lights are emitted sequentially while maintaining high image quality with highlighted structures.
2Measurement precision
If multiple lights are emitted sequentially, then detailed observation of specific structures is achieved, but feeling of strangeness increases due to movement delay
Solution Approach 1:
By emitting multiple lights continuously and simultaneously, the system captures images of different structures at the same moment, eliminating the temporal mismatch that causes the feeling of strangeness. This maintains detailed observation capability while significantly improving viewability and natural appearance of moving structures like blood vessels.
3Measurement precision
If sequential emission of lights is used, then contrast of specific structures is enhanced, but synchronization between object and structure movement is lost
Solution Approach 1:
The simultaneous and continuous emission of multiple lights with different wavelength bands ensures that images capturing both the luminance component and specific structures are obtained at the exact same moment. This maintains the contrast enhancement for specific structures while ensuring perfect synchronization between object movement and structure movement, eliminating the desynchronization problem.

AI summary
An endoscope apparatus includes an illumination device emitting a plurality of lights with different wavelength bands at least two different timings in time series, and a processor including hardware. The plurality of lights includes a first light and a second light. The processor is configured to generate a highlighted image in which a specific structure under a mucus membrane is highlighted, based on a plurality of images obtained by the emission of the plurality of lights. The illumination device emits the first light and the second light continuously. The first light has a first wavelength band corresponding to a luminance component of the highlighted image. The second light has a second wavelength band that enables capturing of an image of the specific structure with higher contrast than the first light.
