Abstract: There are provided a lens barrel, an imaging device body, and an imaging device that can reduce a deviation in a blurred image of oblique luminous flux caused by an APD filter.A lens barrel includes a first lens optical system and a second lens optical system serving as lens optical systems including focus lenses, a diaphragm that changes the amount of an incident ray and emits the incident ray, a first APD filter that is disposed on a light-incident side of the diaphragm, and a second APD filter that is disposed on a light-emitting side of the diaphragm. Since the amount of a reduced upper ray L1 of oblique luminous flux and the amount of a reduced lower ray L2 thereof are made to be substantially equal to each other by the first APD filter and the second APD filter, a deviation of a blurred image is reduced.

Abstract: A phase difference AF processing unit (19) connects detection signals of phase difference detection pixels (52A) in an AF area (53), connects detection signals of phase difference detection pixels (52B) in the AF area (53), and performs a correlation operation with respect to detection signal groups after connection to generate a defocus amount when it is determined that a subject image formed in the AF area (53) includes a high frequency component. The phase difference AF processing unit (19) performs a correlation operation with respect to detection signal groups of phase difference detection pixels (52A, 52B) in each pair line in the AF area (53) to generate the defocus amount when it is determined that the subject image formed in the AF area (53) does not include a high frequency component.

Abstract: A phase difference AF processing unit of a digital camera including an imaging element that captures an image of an object through a lens device including an APD filter and includes a pair of phase difference detection pixels calculates a parameter related to a ratio of a phase difference between detection signals detected by each of the phase difference detection pixels to an amount of defocus based on the incident angle range of light on the pair of phase difference detection pixels through the lens device, the transmittance of a region of the APD filter through which light in the incident angle range passes, and a light reception sensitivity distribution indicating the light reception sensitivity of each of the phase difference detection pixels for each incident angle of light and calculates the amount of defocus using the parameter and the phase difference.

Abstract: The image acquisition section acquires a first image and a second image output from an image pick-up device. A parallax computation section computes parallax indicating the amount of displacement between each of the pixels in the first image and corresponding pixels in the second image acquired by the image acquisition section. The generation section generates a first display image based on a third image output from the image pick-up device, and generates a second display image for use in focus verification based on the first and second images acquired by the image acquisition section. The change section changes the resolution of at least the second display image from out of the first display image and the second display image generated by the generation section according to the parallax computed by the parallax computation section.
