An imaging apparatus includes a solid-state imaging device which is provided with plural pixels arranged in two-dimensional array form on a photodetecting surface of a semiconductor substrate, pixels on even-numbered rows are shifted from pixels on odd-numbered rows by a half pixel pitch, color-filters are Bayer-arranged over the respective pixels of the odd-numbered rows, and color-filters are Bayer-arranged over the respective pixels of the even-numbered rows; and an imaging device driving section for reading shot image signals of the pixels of the odd-numbered rows and shot image signals of the pixels of the even-numbered rows divisionally in separate frames. A color contamination correction is performed on a shot image signal of a pixel of attention using shot image signals of plural pixels around the pixel of attention among shot image signals, read out divisionally, of the pixels of one of the odd-numbered rows.
