Abstract: The disclosure relates to an imaging system which is designed for two-dimensional, spatially resolved measurement of radiometric and/or photometric measured variables, for example the color coordinates of light emitted by a test object. An image sensor is provided for receiving a first part of the light and for generating a two-dimensional digital image of the light emission of the test object. A measuring unit receives a second part of the light and detects radiometric and/or photometric measured variables for different measuring spots or measuring angles. A computing unit transforms the image values of at least a few image points of the generated image, the transformation taking into account the measured variables detected for the measuring spots or measuring angles. The disclosure provides a system which is improved in relation to the prior art. For example, determining the color coordinates when measuring displays with spatially inhomogeneous spectral emission is more precise than in the prior art.

Abstract: A method for operating an internal combustion engine working according to the Otto principle, in which fuel, particularly gasoline, is injected directly into a combustion chamber and is inflamed by self-ignition.
