Abstract: A display system comprises a color sequential display (201) having a backlight (205) comprising several backlight segments and a light modulating panel (207) comprising pixels having controllable light transmission. A backlight unit (211) determines, for a plurality of backlight segments, backlight chromaticities for fields of an image in response to the image content. An order unit (217) determines a sequential order of the backlight chromaticities for each of the plurality of backlight segments for the image in response to the chromaticities. A driver (219) generates a backlight drive signal for the backlight (205) corresponding to the chromaticities and sequential order. A modulating processor (213) determines light modulating values for the pixels in response to the chromaticities, the sequential order and the image. A driver (221) then generates a light modulating drive signal for the light modulating element corresponding to the light modulating values.

Abstract: It is the object of a method for measuring the vessel diameter of optically accessible blood vessels to measure vessel diameters of optically accessible blood vessels in a simple manner based on digital images and with high accuracy even when the vessel diameter is on an order of magnitude at which the determination of the diameter by image point counting is associated with an unacceptably high error. According to the invention, the vessel diameter is determined photometrically from the logarithmized ratio of the intensities of the reflection of the vessel-free environment of the blood vessel and of the reflection of the blood vessel, which intensities are determined in a first monochromatic image.

Abstract: The invention is directed to a method for the spectrometric determination of the oxygen saturation of blood in the presence of optical disturbance variables in which transmission measurements and reflection measurements are carried out in at least two wavelengths that are isosbestic for hemoglobin and oxyhemoglobin, and at least one other wavelength at which the extinction of hemoglobin and oxyhemoglobin differ. Corresponding auxiliary functions are defined in the measurement spectrum (M) and in the reference spectra of hemoglobin and oxyhemoglobin, at least two of the measurement values or two of the reference values for the isosbestic wavelengths lying on this auxiliary function. A corrected measurement spectrum (M?) is generated by means of the two auxiliary functions. The oxygen saturation is determined by comparing the changed data of this corrected measurement spectrum (M?) with the data of the reference spectra at the other wavelength.
