Description

Image processing system with improved image quality The present invention relates to an image processing system, and more specifically, to an image processing system that applies image processing technology for image quality improvement. This project (result) is the result of the Phase 3 Leading University Industry-Academic Cooperation Project (LINC 3.0), funded by the Ministry of Education and the National Research Foundation of Korea. Recently, the incidence of inflammatory bowel disease and colorectal cancer (CRC) requiring endoscopic procedures has been increasing, and the demand for endoscopy for the diagnosis and treatment of targeted diseases is surging. Additionally, there is a growing preference for minimally invasive surgery. In line with these trends, investments, funding, and grants from governments and other organizations worldwide are increasing to improve medical infrastructure and the field of endoscopy research. Additionally, more hospitals are investing in purchasing technologically advanced endoscopic equipment and expanding their endoscopy units. Furthermore, the adoption of disposable endoscopes is expanding to prevent the spread of infectious diseases and enhance efficiency and safety, while interest among medical professionals and providers is growing regarding the transition from manual to automated endoscope reprocessing. Consequently, continuous advancements in endoscopic technology are required to achieve more accurate and reliable diagnoses and treatments. Joint-related diseases are on the rise due to the aging population and the increase in extreme sports, and recently, procedures using micro-endoscopes to diagnose affected joints and inject medication are being attempted. However, there are problems such as difficulty in identifying affected areas due to the low image quality and high noise levels of images captured by micro-endoscopes, and side effects occurring because medication is not injected into the precise site.

FIG. 2 is a block diagram illustrating the internal configuration of an image processing device according to one embodiment of the present invention. FIGS. 3 to 7 compare the original image with an image whose quality has been improved through the image processing system of the present invention. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, terms such as "comprising" or "having" are intended to indicate the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.
