Light source device and system for endoscope

Abstract

The invention discloses a light source device and a system for an endoscope. The light source device comprises a light source, a first rotating disc and a driving assembly, wherein the first rotating disc is provided with at least one pair of first light blocking areas which are oppositely distributed and at least one pair of first light transmitting areas which are oppositely distributed; the first rotating disc can switch the first light transmitting areas or the first light blocking areas on the first rotating disc into a light path generated by the light source through rotation; and the driving assembly drives the first rotating disc to rotate relative to the light path generated by the light source, and enables the first light transmitting areas or the first light blocking areas on the first rotating disc to be switched into the light path of the light source to form a 101010 light transmitting form, so an exposure time sequence of a Global Shutter Sensor is generated, wherein 1 represents light transmitting, and 0 represents complete light blocking. According to the above scheme, the 101010 light transmission form is realized by controlling the position of the corresponding light control rotating disc relative to the light path, so the light source matched with the optimal exposure time sequence of Rolling Shutter Sensor image data acquisition is generated.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to the imaging technology of endoscopes. Background technique [0002] Due to the different colors, structures, and components of different tissues and organs, the spectrum of the light source required is also different. Therefore, it is necessary to design the light source spectrum according to the actual needs of tissues and organs for different spectra. In recent years, endoscopic imaging technology has made great progress. Progress, image clarity and contrast have been greatly improved, under ordinary white light illumination, lesions with obvious changes in shape and color (such as raised lumps and sunken ulcers) can be clearly visualized. For tiny, flat early cancer and heterosexual hyperplasia, it is difficult to diagnose or even cause missed diagnosis. In recent years, endoscopy companies have used a large number of technologies such as chromoendoscopy, electronic spectr...

Problems solved by technology

This solution uses two rotating filters to change the optical characteristics of the optical path, but this method is only suitable for the Global Shutter Sensor, and there is no design for the Rolling Shutter Sensor
