Abstract

Apparatus for producing a composite image from a foreground image (FG), showing an object or a scene with a substantially monochrome background, and background image (BG) comprising a first processing unit (R4) for producing a control signal (SEP) for each pixel of the foregoing image (FG), reflecting whether an individual pixel of the foreground image is part of the object or part of the monochrome background, based both on the chromatic values of the pixel and on predetermined chromatic values, describing the color composition of the monochrome background, a selection unit (R5) suffixed to the first processing unit (R4), for calculating the chromatic values of an individual pixel of the composite image from, depending on the control signal (SEP), either the chromatic values of the corresponding pixel of the foreground image (FG) or the chromatic values of the corresponding pixel of the background image (BG), a second processing unit for calculating correction values for the chromatic values of an individual pixel of the composite image, based on the chromatic values of the corresponding pixel of the foreground image (FG) and/or of the background image (BG), in order to achieve a natural pictorial appearance, and an image processing unit suffixed to the second processing unit, for changing the chromatic values of an individual pixel of the composite image corresponding to the correction values, previously calculated by the second processing unit for this pixel.
