Abstract
An image sensor having photosites forming an array (K×L) of K rows and L columns, including a first set of integrator circuits, with a first regulation by analog weighting in blocks of n×n′ photosites, said photosites belonging to n adjacent columns and to n′ adjacent rows, and a second set of integrator circuits, with a second regulation by analog weighting in blocks of m×m′ photosites, said photosites belonging to m adjacent columns and to m′ adjacent rows, n adjacent columns of a first set of columns of the array being connected to n×n′ integrator circuits of the first set, m adjacent columns of a second set of columns of the array being connected to m×m′ integrator circuits of the second set, n columns of the first set alternating with m columns of the second set to form the array of photosites.
