Technical field

The utility model relates to a kind of CCD imaging drive circuit arrangement, particularly a kind of medical reliable more and CCD imaging drive circuit arrangement easily.

Technical background

Existing medical charge-coupled device (CCD, Charge Coupled Device) drive circuit of imaging, can think a kind of interface conversion circuit, mainly be to give its corresponding work clock signal according to the CCD oneself requirement, as for image signal's collection and processing, then finish by the image pick-up card and the PC computer software that are installed on the PC computer main board.There is following defective in existing mode:

One, along with the development of image pick-up card, function is increasing, and applicable scope is more and more wider, requires also more and more highlyer, also is more and more higher to the requirement of the external hardware device that matches with it.

Two, existing mode is on interface conversion circuit, adjusting to some aanalogvoltage parameter of CCD oneself requirement, often use the simulation potentiometer to regulate, this can cause the consistency of product variation, and in the life cycle of product, need detect adjustment termly, so that product can steady operation in life cycle.

Three,,, increased manually the production cycle of also having strengthened product greatly so must do a large amount of adaptive testings and screening to image pick-up card because capture card is a versatility.

The utility model content

The purpose of this utility model be convenient to debug in order to provide a kind of, the drive circuit of CCD imaging that cost performance is higher, to solve prior art problems.

The utility model discloses a kind of medical CCD imaging drive circuit arrangement.
