Endoscope and image processing system thereof

Abstract

The invention provides an endoscope and an image processing system thereof. The system comprises an image sensor and an image processor. The image sensor receives and converts a plurality of light beams and outputs an output signal corresponding to a horizontal line scanning period. The image processor is electrically connected with the image sensor, comprises a signal interception unit and an operation unit and converts the output signal into an integration signal. The signal interception unit intercepts a first part of the corresponding integration signal in a first pulse period of the horizontal line scanning period, thereby acquiring a first signal. The signal interception unit intercepts a second part of the corresponding integration signal in a second pulse period of the horizontal line scanning period, thereby acquiring a second signal. The operation unit carries out difference calculation on the first signal and the second signal, thereby acquiring image pixel data. The pulse number in the first pulse period and the pulse number in the second pulse period are the same.

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...

Problems solved by technology

[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.
