Claim:
A solid state imaging device of the present invention 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 incident light intensity and a readout switch which is connected to the photodiode; a readout wiring L O,n which is connected to readout switches included in 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 the readout wirings L O,1 to L O,N , holds voltage values corresponding to the amounts of 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; and a correction processing section which acquires respective frame data repeatedly output from the signal readout section and applies correction processing thereto, where 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, m1 is an integer not less than 1 and not more than M, and n1 and n2 are integers not less than 1 and not more than N, wherein when any readout wiring L O,n1 of the n1-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 as a pixel portion P m1,n1 among M pixel portions P 1,n1 to P M,n1 of the n1-th column, and defines a pixel portion neighboring the pixel portion P m1,n1 in the n2-th column neighboring the n1-th column as a pixel portion P m1,n2 ; corrects a voltage value corresponding to the pixel portion P m1,n2 in frame data output from the signal readout section by converting the voltage value according to a relational expression containing the voltage value as an input variable; and determines a voltage value corresponding to the pixel portion P m1,n1 in the frame data based on the value after being corrected of the voltage value corresponding to the pixel portion P m1,n2 .
