Abstract

An image analyzing apparatus comprising a source of light for radiating a target object of interest, a measuring light of a first predetermined wavelength and at least one detecting light of a second predetermined wavelength different from the first predetermined wavelength, which detecting light is utilized to detect an optically disturbing component, a camera unit for forming a measured image of the target object radiated by the measuring light and a detected image of the target object radiated by the detecting light, and capable of generating output signals representative of the respective measured and detected images, a processor for deriving an interference equation descriptive of an interference given by the optically disturbing component, on the basis of the measured and detected images outputed from the camera unit, a computer for eliminating the optically disturbing component from the measured image on the basis of the interference equation, and a display device for providing a visual representation of an image output from the computer.

Claims

1. An image analyzing apparatus, comprising:

a source of light for radiating a target object of interest;

a measuring light of a first predetermined wavelength and at least one detecting light of a second predetermined wavelength different from the first predetermined wavelength, said detecting light being utilized to detect an optically disturbing component;

an image forming means for forming on an image receiving surface of at least one camera means a measured image of the target object radiated by the measuring light and a detected image of the target object radiated by the detecting light, and for generating output signals representative of said respective measured and detected images;

means for deriving an interference equation descriptive of an interference given by the optically disturbing component, on the basis of the measured and detected images from the image forming means which automatically and dynamically provides a regression line as a function of each set of measured and detected images;

a processor means for eliminating the optically disturbing component from the measured image on the basis of the interference equation; and

a display means for providing a visual representation of an image output from the processor means.

2. An apparatus as claimed in claim 1, wherein said image forming means comprises a filtering means for selectively filtering the measuring light and the detecting light, a switching means operable to effect a switching of the filtering means, and a camera for forming the measured image and the detected image therein.

3. An apparatus as claimed in claim 1, wherein said image forming means comprises a filtering means for selectively filtering the measuring light and the detecting light, a switching means operable to effect a switching of the filtering means, and at least two cameras each for forming the measured image and the detected image.

4. The image analyzing apparatus as in claim 1, wherein said measuring and detecting lights radiate on the same target object of interest.
