Abstract: Disclosed are a focusing control device which performs focusing control by a phase difference AF method with high accuracy, a lens device, an imaging device, a focusing control method, and a non-transitory computer readable recording medium storing a program. A digital camera includes a phase difference calculation unit which calculates the phase difference between a signal group output from a plurality of pixels 52A and a signal group output from a plurality of pixels 52B, a lens drive control unit which drives a focus lens according to a drive amount corresponding to the phase difference, a phase difference prediction unit which, based on a coefficient for converting a phase difference calculated at an arbitrary time to a drive amount and the difference between a movement amount of the focus lens and the drive amount, calculates a predicted value of the phase difference.

Abstract: A parallax amount between the plurality of images for each subject on the images is calculated, a subject is identified as a subject targeted for display position adjustment, in a case where the subject having an absolute parallax value which exceeds a predetermined amount is successively pictured in more than a predetermined number of frames, using a cross point provisionally set for the plurality of images as a reference, and parallax is adjusted such that the absolute parallax value of the subject targeted for display position adjustment does not exceed a predetermined amount after adjustment.

Abstract: A natural stereoscopic image is displayed and eye strain is mitigated. A face image is detected in a stereoscopic image composed of a left-eye image and a right-eye image. The left- and right-eye images are shifted in such a manner that visual disparity of the detected face image is removed. Furthermore, a display area containing the face image is calculated. The calculated display area is enlarged so as to be displayed over the entirety of the display screen. Since a double image that appears in front of the face image is excluded, the strain upon the eyes of the observer is mitigated.
