    摘要： A projection conversion coefficient acquirer of an image processing apparatus acquires the same number of projection conversion coefficients, which are coefficients for doing projection conversion of an image, as the number of a plurality of reference points at differing positions in the image. A post-projection-conversion image acquirer does projection conversion on the image through each of the projection conversion coefficients, of which there are the same number as the number of the plurality of reference points acquired by the projection conversion coefficient acquirer, and acquires a plurality of post-projection-conversion images from the image, the number of the post-projection-conversion images being the same as the number of reference points. A weighted averager finds a weighted average for each of the coordinates of pixels comprising the plurality of post-projection-conversion images, using a plurality of weightings determined in accordance with distance from the plurality of reference points in the image. A weighted average image acquirer acquires a weighted average image in which the plurality of post-projection-conversion images have undergone weighted averaging by the weighted averager.

    摘要： Spherical visual content represented in an image space may be obtained. The spherical visual content may have been captured by image sensor(s) during a time duration. The spherical visual content may include phenomena caused by motion of the image sensor(s) and/or optical components that guide light onto the image sensor(s). A capture path taken by the image sensor(s) during the time duration may be determined. The capture path may reflect positions and orientations of the image sensor(s) during the time duration. A smoothed path may be determined based on the capture path. The smoothed path may have smoother changes in positions and/or orientations than the capture path. The image space may be warped based on a difference between the capture path and the smoothed path. The stabilized visual content may be determined by projecting the spherical visual content represented in the warped image space to a spherical projection space.

    摘要： The present disclosure relates to an image processing apparatus, an image processing method, and a program that can correct distortion generated in frames caused by a rolling shutter to a degree to which the frames may be viewed. Provided is an image processing apparatus that corrects distortion generated in a frame constituting a moving image, the image processing apparatus including: a first detection unit configured to detect distorted high-frequency components corresponding to high-frequency components of distortion of the frame; a second detection unit configured to detect distorted low-frequency components corresponding to low-frequency components of distortion of the frame; a correction determination unit configured to determine an amount of correction of the distorted high-frequency components; and a correction unit configured to correct the distorted low-frequency components generated in the frame on the basis of the detected distorted low-frequency components and correct the distorted high-frequency components generated in the frame according to the determined amount of correction. The present disclosure can be applied to, for example, a video camera equipped with a CMOS sensor.
