Solid-state imaging device

A solid-state imaging device comprising:

• a light receiving section where M×N pixel units P1,1 to PM,N each including a photodiode that generates charge of an amount according to an incident light amount, a charge accumulating section in which the charge is accumulated, a first switch for outputting data corresponding to an accumulated charge amount in the charge accumulating section, and a second switch for outputting data corresponding to the accumulated charge amount in the charge accumulating section are two-dimensionally arrayed in M rows and N columns;
• a first row selecting section which selects any m1-th row in the light receiving section, and outputs a control signal to each pixel unit Pm1,n of the m1-th row, thereby discharging a junction capacitance section of the photodiode, accumulating the charge generated in the photodiode in the charge accumulating section, and outputting data corresponding to the accumulated charge amount in the charge accumulating section to a readout signal line L1n by closing the first switch;
• a second row selecting section which selects any m2-th row different from the m1-th row in the light receiving section, and outputs a control signal to each pixel unit Pm2,n of the m2-th row, thereby discharging a junction capacitance section of the photodiode, accumulating the charge generated in the photodiode in the charge accumulating section, and outputting data corresponding to the accumulated charge amount in the charge accumulating section to a readout signal line L2n by closing the second switch;
• a first readout section which is connected to N readout signal lines L11 to L1N, for which data output from each pixel unit Pm1,n of the m1-th row in the light receiving section selected by the first row selecting section to the readout signal line L1n , is input thereto, and from which data corresponding to an amount of the charge generated in the photodiode of each pixel unit Pm1,nof the m1-th row is output;
• and
• a second readout section which is connected to N readout signal lines L21 to L2N, for which data output from each pixel unit Pm2,n of the m2-th row in the light receiving section selected by the second row selecting section to the readout signal line L2n is input thereto, and from which data corresponding to an amount of the charge generated in the photodiode of each pixel unit Pm2,n of the m2-th row is output, wherein
• any m3-th row in the light receiving section is selected, and a control signal is output to each pixel unit Pm,3,n of the m3-th row, thereby discharging a junction capacitance section of the photodiode, and
• the first row selecting section and the first readout section, and the second row selecting section and the second readout section operate in parallel with each other (provided that M and N are integers not less than 2, m1 and m2 are integers not less than 1 and not more than M, m3 is an integer not less than 1 and not more than M, and n is an integer not less than 1 and not more than N).
