Efficient method for reading an imaging device using correlated double sampling
Abstract:
A method for reading an imaging device intended for capturing images in a detector including a large number of photosensitive points called pixels organized into a matrix. The pixels of the same column are linked to a column conductor enabling the successive reading of the photosignals acquired by the pixels of the column, the method consisting for each of the pixels in carrying out a correlated double sampling read phase, the read phase comprising an operation of resetting the pixel followed by two read operations, the first without the photosignal, and the second with the photosignal. Three steps are concatenated in succession for the pixels of the same column: 1. a first of the operations of reading the pixel of a first row, 2. one of the operations of reading a second row, 3. a second of the operations of reading the pixel of the first row.
