The processor acquires a virtual viewpoint image showing an aspect of a subject in a case in which the subject is observed from a viewpoint specified by viewpoint information based on a plurality of captured images and the viewpoint information, and outputs, based on the viewpoint information, data for displaying a specific image created in a process different from a process of the virtual viewpoint image, and the virtual viewpoint image on a display.
Abstract:
Provided are an image processing device capable of performing compression processing on a video captured in each video capturing mode according to a first video capturing mode and a second video capturing mode with different capturing conditions. A possible range of a quantization parameter applied in a case where the video is compressed is made different in the first video capturing mode and the second video capturing mode with different capturing conditions. The quantization parameter is determined within a first range in a case of the first video capturing mode, and the quantization parameter is determined within a second range narrower than the first range in a case of the second video capturing mode. In particular, a second upper limit value of the second range is smaller than a first upper limit value of the first range, and a second lower limit value of the second range is larger than a first lower limit value of the first range.
Abstract:
The lens interchangeable digital camera includes a sensor movement type shake correction mechanism that performs a sensor movement operation of moving an image sensor in a direction to cancel a shake. A characteristic data acquisition unit acquires optical characteristic data corresponding to optical characteristics of an imaging optical system of a lens unit mounted on a body mount. A determination unit determines whether or not adaptive optical characteristic data that can be handled by an image correction unit that performs image correction based on the optical characteristic data can be acquired. An operation deciding unit prohibits a shift operation which is at least a part of a sensor movement operation in an uncorrectable state where the image correction based on the adaptive optical characteristic data is not possible since the adaptive optical characteristic data cannot be acquired.

Disclosed is a technique capable of efficiently storing and retaining characteristic data (a restoration filter or the like) of an optical system used for a restoration process in a storage unit with limited storage capacity in consideration of the degree of image restoration. An image processing device includes a characteristic data storage unit 42 which is capable of storing characteristic data of a plurality of types of optical systems, and a restoration processing unit which subjects source image data to a restoration process using a restoration filter based on a point spread function of an optical system to acquire recovered image data. In case where storing new characteristic data in the characteristic data storage unit, characteristic data which is stored in the characteristic data storage unit 42 is controlled based on a restoration evaluation value which is allocated to characteristic data according to the type of optical system.
