Claim:
A solid state imaging device comprising: a photodetecting section including M×N pixel portions P 1,1 to P M,N two-dimensionally arrayed in M rows and N columns, each including a photodiode which generates charges as much as an incident light intensity and a readout switch connected to the photodiode; a readout wiring L O,n which is connected to readout switches included in the M pixel portions P 1,n to P M,n of the n-th column in the photodetecting section, and reads out charges generated in a photodiode included in any of the M pixel portions P 1,n to P M,n via the readout switch included in the pixel portion; a signal readout section which is connected to readout wirings L O,1 to L O,N , holds voltage values corresponding to charges input through the readout wirings L O,n , and successively outputs the held voltage values; a controlling section which controls opening and closing operations of readout switches included in N pixel portions P m,1 to P m,N of the m-th row in the photodetecting section, controls voltage value output operations in the signal readout section, and makes the signal readout section repeatedly output voltage values corresponding to the amounts of charges generated in the photodiodes included in the M×N pixel portions P 1,1 to P M,N in the photodetecting section as frame data, provided that M and N are integers not less than 2, m is integers not less than 1 and not more than M, n is integers not less than 1 and not more than N, m 1 is an integer not less than 1 and not more than M, n 1 and n 2 are integers not less than 1 and not more than N, and k is an integer; and a correction processing section which acquires respective frame data repeatedly output from the signal readout section and applies correction processing thereto, wherein when any readout wiring L O,n1 of the n 1 -th column among the readout wirings L O,1 to L O,N is broken, the correction processing section: defines a pixel portion which is not connected to the signal readout section due to the breakage of the readout wiring L O,n1 among M pixel portions P 1,n1 to P M,n1 of the n 1 -th column as a pixel portion P m1,n1 , and defines a pixel portion neighboring the pixel portion P m1,n1 in the n 2 -th column neighboring the n 1 -th column as a pixel portion P m1,n2 ; corrects a voltage value V k corresponding to the pixel portion P m1,n2 in frame data F k output k-th from the signal readout section based on voltage values V k , V k−1 , and V k−2 corresponding to the same pixel portion P m1,n2 in the frame data F k and at least two frame data F k−1 and F k−2 just before the frame data F k ; and determines a voltage value corresponding to the pixel portion P m1,n1 in the frame data F k based on a value after being corrected of the voltage value corresponding to the pixel portion P m1,n2 .
