Abstract
The invention relates to matrix image sensors intended in particular for digital photography. The invention provides a driver in each pixel that allows exposure control common to the entire matrix. The driver comprises five transistors, a photodiode and, apart from a supply conductor and a ground, four control conductors, these being an exposure control conductor common to all the pixels of the matrix; a row selection conductor common to all the pixels of any one row; a reset conductor common to all the pixels of any one row; and a column conductor for collecting the signal read on the pixels during row-by-row reading of the charges photogenerated in the pixels of the matrix.
