Patent number: 11889979Abstract: A dermatoscope or endoscope inspection device which can be calibrated at high accuracy to be able to focus at a certain depth, e.g. below the top surface of the skin. A calibration pattern is provided or can be located at a reference viewing surface of an inspection device such as a dermatoscope or endoscope. It is important for a dermatoscope to know with the best accuracy available at what absolute depth below the top of the skin the device is focused. The dermatoscope or endoscope inspection device includes focusing means and by knowing a relationship between a digital driving level which shifts the focus position of the focusing means and the corresponding absolute change in focus depth, it is possible to know how deep the device is focused in absolute terms below the top of the skin.Type: GrantFiled: December 30, 2016Date of Patent: February 6, 2024Assignee: BARCO NVInventors: Tom Kimpe, Frederik Toune, Bart Diricx, Elie De Brauwer, Albert Xthona, Johanna Rousson, Peter Nollet

Publication number: 20190350513Abstract: A dermatoscope which can focus at a certain depth, e.g. below the top surface of the skin. Light sources are provided for creating shadows of a skin lesion and an image acquisition device to take images from which a 3D reconstruction can be made.Type: ApplicationFiled: December 30, 2016Publication date: November 21, 2019Applicant: BARCO NVInventors: Geert CARREIN, Tom KIMPE, Frederik TOUNE, Bart DIRICX, Elie DE BRAUWER, Albert XTHONA

Publication number: 20180040307Abstract: A system and method for separately processing content provided by different applications that is rendered on an attached display. The content is processed based upon the desired display settings that are appropriate for the particular application delivering content to a particular region of the display. In this way, simultaneously displayed applications may be processed as intended by each application, independent of differences in the display settings assumed by the displayed applications. The processing can include a calibration method for linearizing the output.Type: ApplicationFiled: January 8, 2016Publication date: February 8, 2018Applicant: BARCO N.V.Inventors: Matthew MCLIN, Alireza NASIRIAVANAKI, Albert XTHONA, Tom KIMPE, Johan ROSTANG, Cedric MARCHESSOUX

Patent number: 9721328Abstract: A method to enhance the contrast of a set of pixels each pixels being characterized by a set of color attributes comprising the steps of: determining a first property of the set of pixels; determining a second property of the set of pixels; determining, for each pixel of the set of pixels, a first property of said pixel; and modifying the color attributes of each pixel of the set of pixels as a function of the first and second property of the set of pixels and the first property of said pixel.Type: GrantFiled: September 21, 2015Date of Patent: August 1, 2017Assignee: Barco N.V.Inventors: Albert Xthona, David Qualman

Patent number: 9685109Abstract: A system and method for increasing perceived contrast in a medical display (174) is provided. The method involves temporarily increasing luminance output of at least part of a display (174) in response to a received request for improved visualization. To compensate for the change in luminance especially while the viewer's eyes adapt to the change in luminance, the method includes continuously modifying the display parameters especially during an adaptation period to match an adaptation of the viewer's eyes. The modified parameters at any given may correlate to the degree of adaptation by the viewer's eyes to the change. After a period of time, the display (174) may be returned to its normal operating luminance and corresponding settings, which may be selected to maximize the lifetime of the display (174).Type: GrantFiled: June 5, 2015Date of Patent: June 20, 2017Assignee: Barco N.V.Inventors: Tom Kimpe, Albert Xthona

Patent number: 5442379Abstract: A method and apparatus for generating both a true color and fast pseudo color video signals includes the combination of first and second commercially available RAMDACs. Parallel video data representing the red, blue, and green color components of one or more pixels is provided on a video bus to the inputs of the first and second RAMDACs. A first data portion of the parallel video data is presented to the input of the first RAMDAC, which can represent either a single pixel in the fast pseudo color mode or the most significant pixel data. A second data portion of the parallel video data is presented to the input of the second RAMDAC, which can represent either another single pixel in the fast pseudo color mode or the least significant pixel data. The outputs of the two RAMDACs are combined to provide true color video signals in a first RAM programming mode, and the respective outputs of the two RAMDACs are multiplexed to provide fast pseudo color video signals in a second RAM programing mode.Type: GrantFiled: July 15, 1993Date of Patent: August 15, 1995Assignee: Metheus CorporationInventors: Robert A.
