    Abstract: The present technology relates to a data processing apparatus, a data processing method, and a program that are capable of generating calibration data for performing appropriate image processing. The data processing apparatus performs interpolation to generate calibration data for a predetermined focus position by using calibration data for a plurality of focus positions. The calibration data for the plurality of focus positions is generated from a calibration image captured at the plurality of focus positions. The calibration image is obtained by capturing an image of a known object in the plurality of focus positions with a multi-lens camera that captures an image from two or more viewpoints. The present technology is applicable, for example, to a multi-lens camera that captures an image from two or more viewpoints.

    Abstract: The present technology relates to an image processing device, an image processing method, and a program that enable refocusing accompanied by desired blurring. A light collection processing unit performs a light collection process to generate a processing result image focused at a predetermined distance, by shifting the pixels of images of a plurality of viewpoints in accordance with a shift amount and integrating the pixel values. In the light collection process, the pixels are shifted in accordance with a corrected shift amount obtained by correcting the shift amount with correction coefficients for the respective viewpoints. The present technology can be applied in a case where a refocused image is obtained from images of a plurality of viewpoints, for example.

    Abstract: There is provided an image processing apparatus and an image processing method that make it possible to accurately reproduce a blur degree of an optical lens. A ray reproduction section reproduces rays to be incident to a virtual lens, which has a synthetic aperture configured from a plurality of image pickup sections that pick up images at a plurality of visual points, from a real space point in a real space. A light condensing processing section performs a light condensing process in which positioning of a position at which the rays are condensed on a virtual sensor through an emulation lens of an emulation target is performed depending upon an image plane shift position that is a position on the virtual sensor, which is reached by a principal ray emitted from the real space point through the emulation lens, and the ray is condensed on the virtual sensor.

    Abstract: There is provided an information processing apparatus, an information processing method, a program, and an interchangeable lens each capable of appropriately correcting shading of an image having a plurality of viewpoints. A communication unit receives shading information associated with shading of each of a plurality of ommatidium images that are included in a captured image acquired by one image sensor and correspond to images formed by lights respectively concentrated by a plurality of ommatidium lenses that are a plurality of lenses so disposed as not to overlap with each other in an optical axis direction and are included in an interchangeable lens when the interchangeable lens is fitted to a camera body including the image sensor. A correction unit corrects shading of each of the plurality of ommatidium images that are included in the captured image acquired by the image sensor and respectively correspond to the plurality of ommatidium lenses on the basis of the shading information. For example, the present technology is applicable to a camera system or the like which captures an image.
