1. An apparatus for processing a video image, said apparatus comprising:
- an imaging device for producing a gray level image representing the video image;
a frame grabber device for conducting preprocessing functions on the gray level image and for producing a plurality of image types from the gray level image; and
a host computer having a memory for storing the plurality of image types, the plurality of image types being transferred directly from said frame grabber device to said memory of said host computer.

Abstract
An apparatus processes a video image. The apparatus includes an imaging device, a frame grabber device, and a host computer. The imaging device (20) produces a gray level image representing the video image. The frame grabber device conducts preprocessing functions on the gray level image and produces a plurality of image types from the gray level image. The host computer has a memory for storing the plurality of image types. The plurality of image types are transferred directly from the frame grabber device to the memory of the host computer.

11. A method for processing a video image, said method comprising the steps of:
-
capturing a first gray level image from the video image;
processing the first gray level image during said capturing step, said processing step including the step of generating multiple images from the first image; and
transferring data representing the first image and the multiple images directly to the memory of a host computer, said processing step being conducted by a field programmable gate array, the field programmable gate array being located physically apart from the host computer. - View Dependent Claims (12, 13, 14, 15)
