Abstract: Provided is an imaging apparatus capable of performing AF with a high precision regardless of an object while realizing increase in AF speed. When there is an AF instruction, photographing is performed while a focus lens is moved. AF evaluated values are calculated at every position of the focus lens by a contrast AF processing unit. The contrast AF processing unit calculates a sharpness in the vicinity of the maximal point of an evaluated value curve from three AF evaluated values, including the maximum value among calculated AF evaluated values and AF evaluated values calculated at positions in front and rear of a focus lens position corresponding to the maximum value, and position information of the focus lens corresponding thereto, and calculates a focusing position by a calculation method selected from among plural kinds of methods according to the sharpness.

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.
