Claim:
1. A driving method of an imaging device which includes a plurality of unit cells disposed in a matrix in an imaging area, and each including a plurality of photoelectric converting units each accumulating electric carriers based on incident light, wherein each of the plurality of unit cells positioned in a first area for phase difference detection within the imaging area outputs a first signal based on the electric carriers accumulated in only a part of the plurality of photoelectric converting units of corresponding at least one of the unit cells, and a second signal based on the electric carriers accumulated in the plurality of photoelectric converting units of corresponding at least one of the unit cells, each of the plurality of unit cells positioned in a second area other than the first area, within the imaging area, outputs a second signal based on the electric carriers accumulated in the plurality of photoelectric converting units of corresponding one of the unit cells, the imaging device outputs signals based on the first signals in the first area, and signals based on the second signals in the first area, the imaging device outputs signals based on the second signals in the second area, and the imaging device sets a number of the unit cells based on a signal based on the second signals in the second area to a number larger than a number of the unit cells based on a signal based on the first signals in the first area, and larger than a number of the unit cells based on a signal based on the second signals in the first area.
