Claim Text:
1. An imaging device to which a lens device is detachably mounted, comprising: an imaging element that includes multiple pixels for imaging arranged into a two-dimensional array and multiple pixels for phase difference detection on a light receiving surface and that images a photographic subject through the lens device; a communication unit that performs communication with the mounted lens device; a lens information acquisition unit that acquires lens information that is information specific to the lens device, from the lens device through the communication unit; a gain correction processing unit that performs gain correction processing which corrects an output signal of the pixel for phase difference detection in an imaging-obtained image signal that is obtained by the imaging element imaging the photographic subject, by multiplying the output signal by a gain value; an interpolation correction processing unit that performs interpolation correction processing which corrects the output signal of the pixel for phase difference detection in the imaging-obtained image signal by replacing the output signal with a signal that is generated using an output signal of the pixel for imaging that is in the vicinity of the pixel for phase difference detection and that detects the same color as the pixel for phase difference detection; a correction method selection unit that selects, according to the lens information that is acquired by the lens information acquisition unit, any of a first correction method in which the output signals of all the pixels for phase difference detection in the imaging-obtained image signal are corrected by the interpolation correction processing unit, and a second correction method in which the output signals of all the pixels for phase difference detection in the imaging-obtained image signal are corrected by the gain correction processing unit; and an image processing unit that corrects the output signal of the pixel for phase difference detection in the imaging-obtained image signal, using the method that is selected by the correction method selection unit.
