PROBLEM TO BE SOLVED: To reduce the time necessary for imaging of one frame in a solid imaging apparatus having a structure in which pixel arrays formed on two substrates are tiled in the direction of rows.SOLUTION: The solid imaging apparatus 1 comprises: a semiconductor substrate 3A having a pixel array 10A with pixels arrayed in M rows and NA columns a semiconductor substrate 3B having pixel array 10B with pixels arrayed in M rows and NB columns, and a signal output part 20. The first column of the pixel array 10B is disposed along the NA-th column of the pixel array 10A. The signal output part 20 outputs digital values corresponding to the respective columns from the first to the n-th column (2&len
