20100188518 | IMAGING APPARATUS AND METHOD OF DRIVING IMAGING APPARATUS - An imaging apparatus includes plural pixel portions each having a photoelectric conversion portion and an electric charge accumulating portion that accumulates electric charges. Imaging signals corresponding to amounts of the electric charges in the electric charge accumulating portions are read out. The imaging signals of two adjacent lines of pixel portions are added. In still-image shooting, a first operation and a second operation are performed every exposure operation. The first operation reads out the imaging signals using a pattern containing combinations of two adjacent lines, adds the imaging signals of the two adjacent lines and outputs the added image signals as a field signal. The second operation reads out the imaging signals using a pattern being obtained by shifting the pattern for the first operation by one line, adds the imaging signals of the two adjacent lines and outputs the added image signals as another field signal. | 07-29-2010 |
