Abstract
An endoscopic imaging system providing for correction of image signals characteristic of non-uniform illumination. The system also enabling correction of an image signal in the event of the failure, or performance degradation, of one or more imaging elements. The system also enabling correction moderation addressing dynamic range issues, centering, counter-rotation, alignment and orientation.

A method of correcting, in a digital domain, an image signal characteristic of non-uniform illumination and/or non-uniform optical characteristics in an endoscopic imaging system, the image signal representing an image associated with a target site, comprising:
- performing a characterization operation;
- establishing, based at least in part on the characterization operation, one or more correction factors;
- acquiring image data associated with the target site;
- and
- applying, using at least one of the established correction factors, a correction operation as to selected image data.
An endoscopic imaging system, comprising:
- system components constructed and arranged to perform a characterization operation;
- establish, based at least in part on the characterization operation, one or more correction factors;
- acquire image data associated with the target site;
- and apply, using at least one of the established correction factors, a correction operation as to selected image data.
An endoscope, comprising:
- elements that are constructed and arranged to perform a characterization operation;
- establish, based at least in part on the characterization operation, one or more correction factors;
- acquire image data associated with the target site;
- and apply, using at least one of the established correction factors, a correction operation as to selected image data.
An imaging system, comprising:
- means for performing a characterization operation;
- means for establishing, based at least in part on the characterization operation, one or more correction factors;
- means for acquiring image data associated with the target site;
- and
- means for applying, using at least one of the established correction factors, a correction operation as to selected image data.
