Abstract:
1. Device for the pixel-by-pixel photoelectric measurement of a planar or flat object to be measured, comprising a two-dimensional array of light converter elements for producing electric signals in response to light remitted by the object to be measured; imaging means for imaging the object to be measured onto the two-dimensional array of light converter elements; filters provided in the imaging light path for wavelength selective filtering of the measurement light impinging on the light converter elements; signal processing means for processing the electrical signals produced by the light converter elements and for converting them into corresponding digital raw measured data; and data processing means for processing of the raw measured data into image data representing the colors of the individual pixels of the measured object, the data processing means being constructed for carrying out a scattered light correction for reducing scattered light influences; wherein the data processing means is constructed for calculating from the measured data of the measured object or object to be measured a scattered light image and subtracting the latter pixel-by-pixel from the measured data of the measured object.
