Zusammenfassung:An image sensor (10) comprises an array (11) of rows (51, 52) and columns (71 to 73) of pixels (30), a first number N of connection lines (58 to 60) each connected to a row of pixels (30) of the array (11), a voltage regulating circuit (15) having an output (61), a first terminal (66), and a driver circuit (12). The driver circuit (12) has N switches (62 to 64) each coupled to one of the N of connection lines (58 to 60) and to the output (61) of the voltage regulating circuit (15), and N further switches (67 to 69) each coupled to one of the N connection lines (58 to 60) and to the first terminal (66). The first number N is at least two.
