Abstract:
1. A method of driving a photosensitive device having a matrix of photosensitive pixels distributed at the intersections of rows and columns of the matrix, the method comprising: subjecting the matrix to an image cycle that includes a resetting phase prior to an image acquisition phase, wherein rows of the matrix are distributed in several groups; during the resetting phase, resetting all the rows of any one group simultaneously; and resetting each group of rows in succession, wherein all the rows in any one group are disjoint and the distribution of the rows in a group form a comb; wherein rows forming a group are uniformly spaced apart with a pitch equal to α=N/n, where N is the total number of rows of the matrix, n is the number of rows per group, α>1, and wherein the comb is moved at least α−1 times so as to scan all of the rows of the matrix.
