Abstract

The invention discloses a CCD electronic imaging device and an endoscope with the CCD electronic imaging device therein. The CCD electronic imaging device comprises a front drive module, an image processing and signal drive module and a display module, the front drive module is in drive connection with a CCD image pick-up unit, and the image processing and signal drive module is connected with the front drive module through a cable and further connected with the display module; the front drive module is further provided with a drive signal impedance matching circuit, and the drive signal impedance matching circuit is used for matching the characteristic impedance of the cable with the load impedance; the image processing and signal drive module generates drive signals, the drive signals are transmitted to the front drive module through cable, and meanwhile, the image processing and signal drive module receives image signals transmitted from the front drive module through cable, processes images and outputs video signals for display to the display module. The CCD electronic imaging device is simple in structure, convenient to carry, stable in signal when using, and good in imaging quality.

Description

technical field [0001] The invention relates to an electronic imaging device of a CCD imaging element, in particular to a CCD electronic imaging device and an endoscope thereof. Background technique [0002] In recent years, endoscopes with CCD imaging devices have been widely used in medical and industrial fields. The transmission cable that constitutes the transmission cable from the CCD imaging element at the front end of the endoscope to the processor has a length of about several meters. The driving signal frequency of the CCD is high and the wavelength is short, that is, the wavelength is comparable to the length of the cable. The signal is reflected, and the reflected signal Superimposing on the original signal will change the waveform shape of the original signal, resulting in waveform distortion, which will affect the imaging quality. [0003] With the further pursuit of high-quality images in the medical and industrial fields, the requirements for the integrity of...
