Assignee: LEICA INSTRUMENTS (SINGAPORE) PTE LTD.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 13:
14. An image processor for a medical observation device, the image processor comprising:
an input section configured to receive a time series of input frames representing electronically coded still images of the object, each input frame containing at least one observation area, the observation area comprising at least one pixel;
a memory section in which a set of component signals is stored;
a computing section configured
to determine the fluorescent light intensity in the observation area of one input frame of the time series over at least one fluorescence emission wavelength of the fluorophore in the observation area,
to join the fluorescent light intensity of the observation area of the one input frame with fluorescent light intensities of previous input frames of the time series to generate a time sequence of fluorescent light intensity in the observation area, and
to decompose the time sequence into a combination of the component signals in the set;

an image generator section configured to generate an output frame by joining at least one input frame of the time series with the observation area which is assigned a pseudocolor from a color space, the pseudocolor depending on the combination and
an output section configured to output the output frame;, wherein each component signal is a discrete or analytic time curve representing the course of fluorescence light intensity over time of the fluorophore in a specific type of tissue, and the computing section is further configured to compose a new set of component signals from the component signals of the combination as a replacement of the set.
