Patent number: 6400849Abstract: An image processing method using memory management and pre-computed look up tables to speed up computations. Application of filters along directions other than image rows is simplified using several structured processing approaches that improve image data cache-ability. Time consuming or repeated computations are pre-computed and stored as look up tables to reduce the time required for image processing and to remove or reduce the need for special purpose image processing hardware.Type: GrantFiled: October 20, 2000Date of Patent: June 4, 2002Inventors: Shih-Jong J. Lee, Louis R. Piloco, Larry A. Nelson

Patent number: 5912699Abstract: A high speed image capture apparatus includes a camera with an integration period between consecutive flashes of an illuminating light pulse, where the camera has an image read out period and an image output. A timer for provides a strobe output representative of the start of a flash. An image capture apparatus captures a first image during the integration period and a second image within a predetermined time after capturing the first image but before the image read out period has elapsed so as to substantially increase a rate of producing usable image outputs. The image capture apparatus is coupled to the strobe output and the image output.Type: GrantFiled: September 7, 1994Date of Patent: June 15, 1999Assignee: NeoPath, Inc.Inventors: Jon W. Hayenga, Louis R. Piloco

Patent number: 5875258Abstract: A suite of tests and parameter monitoring methods for at least five major subsystems that are found in most automated image processing systems, as well as calibration routines for three major system functions. The five areas of subsystem verification include processing quality, illumination quality, image collection quality, autofocus quality, and position quality. An automated biological specimen analysis system uses self measures of system parameters to provide a system status. The system status is reported to the user.Type: GrantFiled: August 26, 1996Date of Patent: February 23, 1999Assignee: NeoPath, Inc.Inventors: William E. Ortyn, Louis R. Piloco, Jon W. Hayenga

Patent number: 5677762Abstract: An illumination device provides temporally, spatially and angularly stable illumination for microscopic evaluations. An arc lamp serves as the light source. An input optical train gathers and focuses the light through an aperture stop to place an image of the arc incident on an input aperture of a light pipe. The magnification of the arc lamp is chosen to reduce the variation due to occlusion. The light pipe spatially homogenizes the light while preserving the angular integrity. An exit window may be placed over the exit aperture of the light pipe to keep dust and debris out of focus. Another optical train receives the spatially homogenized, angularly preserved light and may focus a many arclet images to fill the pupil of a condenser lens. The condenser lens also may focus the exit aperture of the light pipe onto or near the specimen on a microscope slide. A feedback system samples the light and corrects for residual temporal variations by electronically modifying the image as it leaves a CCD.Type: GrantFiled: May 16, 1996Date of Patent: October 14, 1997Assignee: NeoPath, Inc.Inventors: William E.
