Abstract:
1. 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: 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.
