Patent ID: 7907190

Claim:
A method of correcting signal differences between at least two adjacent parts of a radiation-sensitive sensor, each said adjacent parts containing a contiguous set of radiation-sensitive sites read out through a respective separate electronic processing means, said contiguous sets being collinear, said method comprising the steps of: increasing the perimeter of the border between said adjacent parts of the sensor read out through separate electronic processing means; using at least one set of adjacent values from each said adjacent parts to compute a correction to be applied to a signal read out of at least one of said adjacent parts; wherein said step of increasing the perimeter comprises: shifting a first line so that N sites belonging to a first of said adjacent parts are enabled to be read out through a second one of said separate electronic processing mean; reading out said shifted first line through said respective separate means; shifting a second line so that N sites belonging to a second of said adjacent parts are enabled to be read out through the first one of said separate electronic processing means; reading out said shifted second line through said respective separate means; wherein each said first and second lines has N dummy pixels at each end thereof; additionally comprising, after each said reading out steps, the step of aligning the two parts of each said read out lines; and wherein said aligning comprises using at least one FIFO buffer.
