Abstract

The invention discloses an automatic equalization pre-emphasis adjusting system and an endoscope system. The automatic equalization pre-emphasis adjusting system comprises an image signal link, the image signal link is provided with a plurality of relay chips, and the output end of the image signal link is connected with a relay chip gear adjusting IC. The relay chip gear adjusting IC comprises a data analysis module, a equalization pre-emphasis gear control module and a data comparison module. A signal output end of the image signal link is connected with the data analysis module, a signal output end of the data analysis module is connected with the equalization pre-emphasis gear control module and the data comparison module, and a signal output end of the data comparison module is connected with a signal input end of the equalization pre-emphasis gear control module. A signal output end of the equalization pre-emphasis gear control module is connected with the relay chips. The relay chip gear adjusting IC can automatically adjust the gears of the relay chips, it is guaranteed that the optimal equalization pre-emphasis effect is set for the relay chips under the condition that hardware links are discrete, and the applicability of the system is greatly improved.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to an automatic balance pre-emphasis adjustment system and an endoscope circuit system. Background technique

[0002] As a kind of medical equipment, the endoscope system mainly consists of a mirror body, a signal connection line and an image processor. The processor is used to process the image by the image processor, and output the processing result to the terminal for display.

[0003] Electronic endoscopes usually use high-speed serial signals for image transmission. Due to the unique structural characteristics of the system, the image transmission distance is extremely long, that is, high-speed differential signals need to be transmitted for several meters. In view of long-distance transmission, in order to ensure the quality of the transmitted graphics, it is necessary to perform signal equalization and pre-emphasis processing on the key nodes of the system.
