Example Embodiment

[0050] Such as figure 1 As shown, the medical color electronic endoscope image dead pixel detection device of the present invention includes: an image acquisition unit 1, an RGB decomposition unit 2, a binarization pre-judgment unit 3, a display and input unit 4, and a dead pixel judgment unit 5. . The image acquisition unit 1 is connected to the RGB decomposition unit 2; the RGB decomposition unit 2 is also connected to the binarization pre-judgment unit 3; the binarization pre-judgment unit 3 is also connected to the display and input unit 4 and the bad pixel judgment unit 5 respectively. Connection; the bad pixel judgment unit 5 is also connected to the display and input unit 4.

[0051] To use this device for dead pixel detection, the operator must first connect the image output interface of the electronic endoscope under test to the image acquisition unit 1 of the device through a data line. Then, relevant information such as the shooting information and the tested endosco...

Abstract

A medical colorful electronic endoscopy image bad point detection device comprises an image acquisition unit, an RGB decomposition unit, a binaryzation pre-judging unit, a display and input unit and a bag point judgment unit, wherein the image acquisition unit is connected with the RGB decomposition unit and acquires and transmits an output image of a detected electronic endoscopy to the RGB decomposition unit, and the RGB decomposition unit is connected with the image acquisition unit and the binaryzation pre-judging unit respectively, decomposes the acquired original image into three component images R, G and B and transmits the component images to the binaryzation pre-judging unit. The display and input unit is connected with the binaryzation pre-judging unit and the bag point judgment unit. The binaryzation pre-judging unit is connected with the RGB decomposition unit, the display and input unit and the bag point judgment unit respectively. The bag point judgment unit is connected with the binaryzation pre-judging unit and the display and input unit respectively and perform bag point judgment. The medical colorful electronic endoscopy image bad point detection device facilitates bad point detection in all fields of usage links, considers recognition efficiency and further effectively decreases mistaken judgment.

Description

technical field [0001] The invention relates to a device for detecting dead pixels in medical color electronic endoscope images, belonging to the technical field of detecting dead pixels in electronic endoscope images. Background technique [0002] Medical electronic endoscope is an important medical diagnosis and treatment equipment. Image dead pixels are an important factor affecting the image quality of electronic endoscopes and the core index for evaluating the performance of electronic endoscopes. They affect the diagnosis and treatment effect to a large extent and are related to patient safety. Color electronic endoscope is a kind of medical endoscope that develops rapidly and is widely used in recent years. Color electronic endoscope is a high-end medical equipment, the price is relatively expensive, and the equipment is delicate and fragile. Users and medical institutions usually pay special attention to the dead pixels of color electronic endoscope images. In the...
