Claim:
1. A method for reading an imaging device for capturing images and including a plurality of pixels organized into rows and columns forming a matrix, the pixels of a same column being linked to a column conductor enabling a successive reading of photosignals acquired by the pixels of the column, the method comprising, for each of the pixels: carrying out a correlated double sampling read phase, the read phase comprising an operation of resetting the pixel followed by two read operations, a first read operation being without the photosignal, and a second read operation being with the photosignal, wherein following 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 (I), (2) one of the operations of reading a second row (I+1), and (3) a second of the operations of reading the pixel of the first row (I) and wherein the pixels are 3T pixels and such that, for the first row (I), a reset operation, a first read operation, an image capture operation and a second read operation are concatenated for a current frame t, and a reset operation is concatenated for a frame (t+1) after the current frame (t), such that, for a second row (I+1), a second read operation is concatenated for a frame (t−1) before the current frame (t), a reset operation, a first read operation, an image capture operation and a second read operation are concatenated for the current frame (t), and such that the second read operation of the second row (I+1) for the preceding frame (t−1) carried out in step (2) and the reset operation of the first row (I) for the current frame (t) are carried out simultaneously.
