An imaging element includes a plurality of photoelectric conversion units that respectively receives lights passing through different partial pupil regions with respect to lights from a shooting lens. Each of the pixel units has first and second photoelectric conversion units, and a video image signal processing unit and a phase difference signal processing unit obtain and process each of signals output from the first and second photoelectric conversion units. A video image signal processing unit obtains the signals of the first and second photoelectric conversion units having the setting of different output conditions of pixel signals, and performs a dynamic range expanding process of the image signal. The phase difference signal processing unit corrects the signals of the first and second photoelectric conversion units and performs focus detection of the phase difference detection method. The video image signal processing unit and the phase difference signal processing unit execute the respective signal processes in parallel in a single shooting operation.
