Camera for high-definition CMOS endoscope

Abstract

The invention relates to a camera for a high-definition CMOS endoscope. The camera for the high-definition CMOS endoscope comprises an image sensor, a system sequence circuit, an LVDS coding circuit, a power supply unit and SCCB control signals. The output end of the system sequence circuit is connected with the input end of the image sensor. The output end of the image sensor is connected with the input end of the LVDS coding circuit. The output end of the LVDS coding circuit outputs the signals. The SCCB control signals are input into the image sensor. The power supply unit is electrically connected with the image sensor, the system sequence circuit and the LVDS coding circuit. A CMOS sensor with the resolution ratio up to 720 P is adopted, the frame rate can reach 30fps, the size of the camera is reduced, the number pixel is increased, video signals are output by adopting an LVDS coding technology for coding, the resolution is improved, the transmission distance is increased, the control interface of the camera is opened, the exposure mode of the camera can be set through a rear end processing chip, and the light reflection problem caused during metal object observation is solved.

Description

technical field [0001] The invention belongs to the field of endoscopes, in particular to a camera head of a high-definition CMOS endoscope. Background technique [0002] There are two types of endoscope camera sensors, one is CCD (Charge-coupled Device, charge-coupled device), and the other is CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor). At present, the 720P high-definition endoscope cameras on the market all use CCD sensors. The size of the camera is large, which greatly increases the size of the detection end, making it difficult for the endoscope to be used in a small space. The current popular CMOS endoscope cameras have less than 440,000 pixels. The pixels are too low to observe the details of the target surface, which affects the diagnosis of faults by endoscope users. In addition to the shortcomings of insufficient pixels, the exposure mode, white balance and other parameters of traditional CMOS endoscope cameras cannot be...

Problems solved by technology

[0005] The present invention provides a camera head of a high-definition CMOS endoscope, which aims to solve the problem that the existing endoscope camera head has a large volume and many power supply and data transmission lines, and the CMOS image sensor and LVDS code must be packaged in an endoscope with a diameter of less than 7mm. The assembly of the detection end is difficult, the resolution is low, the transmission distance is short, and the observation of metal objects encounters reflection problems
