摘要： A system and method for increasing perceived contrast in a medical display is provided. The method involves temporarily increasing luminance output of at least part of a display 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 may be returned to its normal operating luminance and corresponding settings, which may be selected to maximize the lifetime of the display.

摘要： 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.

摘要： 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).

摘要： 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.
