ABSTRACT:
Aspects of the subject matter described herein relate to reducing error in images obtained from an image-acquiring system. An image-acquiring system may be modeled as light received from a primary path, light received from a secondary path, and light received from all other paths. Light received from the secondary and other paths may cause error in images captured by the image-acquiring system. By compensating for this light, the error may be reduced. Other aspects are described in the specification.
