A process is disclosed for reading out an image sensor matrix having sensor elements arranged in rows and columns and which produces television signals representative of an image. Read-out of the matrix for the production of the image consists of two sub-processes which follow one another in time. In the first sub-process, the items of information of the sensor elements provided in each individual row are read out one after another. The rows are read out consecutively. In the second sub-process, summed items of information are read out from groups of rows. Each row group may consist of two or more rows. As the read-out of a given group proceeds, corresponding items of information in each of the rows are summed together during the read-out so as to form the sums of corresponding items of information. The groups include all of the rows of the matrix and the groups are read out consecutively. The sums of the items of information are then each divided so as to be compatible with the items of information during the read-out of the individual rows. Alternatively, the items of information read out in the first sub-process are multiplied to be compatible with the sums of the items of information created during the second sub-process.
