A digital output color image (160) is from the digital white-light color image and the digital fluorescence-light color image, the digital output color image comprising a plurality of output pixels (150c).

The invention relates to a data processing device (170) and a computer-implemented method for computing an output color of an output pixel (150c) in an output color image (160) by mixing a background color of a first pixel (150a) in a background color image (114) with an overlay color depending on a light intensity value (204) of a second pixel (150b) in a second image (112). In order to arrive at a color mixture which is adapted to human color perception and thus to retain all information visually recognizable without introducing artifacts, the following steps are performed: The background color coordinates (202) of the background color in a uniform color space (400), the overlay color coordinates (200) of the overlay color in the uniform color space (400) and the light intensity value (204) are retrieved. The background color has a predetermined maximum luminance value (440) and a predetermined minimum luminance value (442) in the uniform color space. The light intensity value is within a range extending from and including a predetermined maximum light intensity value (446) and extending to and including a predetermined maximum light intensity value (448). Further, a luminance line (402) is computed in the uniform color space (400), which extends from the overlay color coordinates (200) to an end point (406) along points having the chroma of the overlay color coordinates (200). The luminance at the end point is lower than the luminance at the overlay color coordinates. A first point (408) on the luminance line (402) is determined, wherein the ratio of the difference between the predetermined maximum luminance value and the luminance of the background color coordinates (202) and the difference between the luminance of the background color coordinates (202) and the predetermined minimum luminance value corresponds to the ratio of the length (410) of the luminance line between the first point (408) and the overlay color coordinates (200) and the length (412) of the luminance line between the end point (406) and the first point (410). Then, an overlay color line (404) is computed which extends straight from the background color coordinates (202) to the first point (408). Further, a second point (414) on the overlay color line (404) is determined, wherein the ratio of the difference between the predetermined maximum light intensity value and the light intensity value and the difference between the light intensity value and the predetermined minimum light intensity value corresponds to the ratio of the length (420) of the overlay color line (404) between the second point (414) and the first point (408) and the length (422) of the overlay color line (404) between the background color coordinates (202) and the second point (414). The color coordinates (206) of the second point (414) in the uniform color space (400) are output as the output color of the output pixel (150c).

Abrégé

Examples relate to a system, a method and a computer program controlling a recording device of a surgical microscope system, and to a corresponding surgical microscope system. The system comprises one or more processors and an interface. The system is configured to obtain input data from one or more sensors or actors of the surgical microscope system via the interface. The system is configured to detect a start or an end of a surgery based on the input data. The surgery involves a use of the surgical microscope system. The system is configured to provide a control signal to the recording device of the surgical microscope system via the interface based on the detected start or end of the surgery. The input data may be used to detect the start or the end of a surgical procedure, which may in turn trigger the activation or deactivation of the recording being performed by the recording device.
