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 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.

摘要： Methods of image calibration and in particular of image calibration having a multiple of colour scales as well as to quantitative imaging such as quantitative medical imaging, or to a display device or to a system for displaying an image, or to a controller of a display, or to software to enable the image calibration, or to a visualization application and a display. The method for processing an image, includes the steps of: —selecting at least one trajectory in a colour space; —defining a transformation which primarily increases perceptual linearity of consecutive points belonging to the at least one trajectory; —applying the transformation to the image. This has the advantage that the perceptual linearity can be restricted to the trajectory.

摘要： A display has a spatial light modulator for dynamically controlling a luminance of each pixel according to an input signal, the spatial light modulator having a non-uniform spatial characteristic, the display also having an optical filter having a spatial pattern to alter the luminance to compensate at least partially for the non-uniform spatial characteristic. An electronic signal processing element applies some pre ompensation predominantly of higher spatial frequencies for the non-uniform spatial characteristic. Such dynamic and optical compensation can enable tuning for different optimizations or for compensating for variations over time. A backlight has an optical source and an optical filter, the source having a color output which has a non-uniform spatial characteristic, and the optical filter having a spatial pattern to alter the color to compensate in part at least for the non-uniform spatial characteristic.
