Abstract

A system for acquiring images during a medical procedure and using the acquired images includes a storage device for storing, for each one of a plurality of users of the system, or for each one of a plurality of medical procedures, or for each one of a plurality of input or output devices, information that indicates one or more processing operations to be performed on images obtained by an input device. A system processor responds to an identity the user who is currently using the system by performing processing operations on the obtained images and applying the images to an output device based on the stored information that corresponds to the current user.

Claims

1. A method of reducing interlaced noise on an interlaced video display device by reducing motion artifacts due to motion that occurs between acquisition of fields of video that comprise a video frame, comprising the steps of:

a) comparing at least one pixel in at least one line of a first field of video with at least one pixel in at least one line of a second field of video that is interlaced with said first field on said video display device, said at least one line of said first field being in close proximity to said at least one line of said second field, said at least one pixel in said first field being in close proximity to said at least one pixel in said second field,

b) determining whether a difference between a value of said at least one pixel in said at least one line of said first field and a value of said at least one pixel in said at least one line of said second field exceeds a fixed value,

c) if said difference between said values of said pixels exceeds said fixed value, replacing said value of said at least one pixel in said at least one line of said second field with a value closer to said value of said at least one pixel in said at least one line of said first field,

d) if said difference between said values of said pixels is less than said fixed value, maintaining said value of said at least one pixel in said at least one line of said second field,

e) performing steps a) through d) above for additional pixels in said at least one line of said first field and said at least one line of said second field, and

f) preforming steps a) through e) above for additional lines of said first and second fields.

2. A method in accordance with claim 1, wherein:

said at least one line of said first field comprises two lines both located immediately adjacent to said at least one line of said second field,

said value of said at least one pixel in said at least one line of said first field comprises an average of a value of a pixel in one of said two lines and a value of a pixel in another of said two lines, and

if said difference exceeds said fixed value, said value of said at least one pixel in said at least one line of said second field is replaced with said average of said values.

3. A processor configured and programmed to process images for display by an interlaced video display device by performing the method of claim 1.
