Endoscope and its image processing system

Abstract

The invention provides an endoscope and its image processing system, which includes an image sensor and an image processor. The image sensor receives and converts the complex light beams and outputs output signals corresponding to the horizontal line scanning period. The image processor is electrically connected to the image sensor and includes a signal interception unit and a computing unit to convert the output signal into an integrated signal. The signal interception unit intercepts the first part of the corresponding integrated signal according to the first pulse period of the horizontal line scanning period to obtain The first signal, the signal intercepting unit intercepts the second part of the corresponding integrated signal according to the second pulse period of the horizontal line scanning period to obtain the second signal, and the computing unit calculates the difference between the first signal and the second signal to obtain image pixel data , the number of pulses in the first pulse period is the same as the number of pulses in the second pulse period.

Description

technical field [0001] The present invention relates to an endoscope image processing system, and in particular to an endoscope with a reduced volume image sensor and its image processing system. Background technique [0002] Existing endoscope is to be made of interconnection of tip head, curved tube, insertion tube and handle. The tip is installed at the front end of the curved tube, and the insertion tube is connected between the curved tube and the handle. Since the endoscope is used for invasive internal surgery or close observation of symptoms or affected areas on patients or observation objects, Therefore, a camera with a camera is installed at the tip, and images of symptoms, affected areas or surgical procedures are captured by the camera and sent to the host computer connected to the endoscope for display. [0003] Since the camera is one of the indispensable components of the endoscope, the improvement of the resolution of the image is also one of the current sub...

[0004] However, the volume of the tip of the endoscope increases, although high-resolution images can be achieved, but the connection between the insertion tube and the tip increases in addition to the number of connecting parts, and the connection of the insertion tube also needs to be enlarged, thus increasing the cost. And when the endoscope is used in the human body, an opening of relative size is required for the human body for the tip and the insertion tube to invade. The size of the opening of the human body corresponds to the diameter of the nozzle inserted into the human body. A burden, if the size of the tip cannot be reduced, then the human body will be burdened more because of the larger size of the nozzle of the tip

[0005] If the size of the tip is reduced in order to reduce the burden on the human body, then the size of the camera will inevitably be reduced, and the resolution of the camera will be reduced accordingly, which will cause problems in observation and may reduce the overall accuracy of surgery or diagnosis of the cause.
