Image processing apparatus, moving-image playing apparatus, and processing method and program therefor to allow browsing of a sequence of images

摘要

To allow a viewer to easily understand the details of a moving image shot by an image capturing apparatus in the case where the moving image is browsed. A camerawork detecting unit 120 detects the amount of movement of an image capturing apparatus at the time of shooting a moving image input from a moving-image input unit 110, and, on the basis of the amount of movement of the image capturing apparatus, calculates affine transformation parameters for transforming an image on a frame-by-frame basis. An image transforming unit 160 performs an affine transformation of at least one of the captured image and a history image held in an image memory 170, on the basis of the calculated affine transformation parameters. An image combining unit 180 combines, on a frame-by-frame basis, the captured image and the history image, at least one of which has been transformed, and causes the image memory 170 to hold a composite image. The composite image generated by the image combining unit 180 is displayed on a display unit 191.

主权项

1. An image processing apparatus comprising:
circuitry configured to: receive a captured moving image captured by an image capturing apparatus; calculate, on a basis of a first captured image included in the captured moving image and a second captured image positioned subsequent to the first captured image along a time axis of the captured moving image, transformation information relating to the first captured image and the second captured image; hold a history image, the history image being a combination of individual captured images including the first captured image, the individual captured images being positioned prior to the second captured image along the time axis of the captured moving image; transform at least one of the history image and the second captured image on a basis of the calculated transformation information; accept a selecting operation of selecting an image to be transformed; combine the history image and the second captured image by writing the second captured image over the history image, at least one of which has been transformed in response to the accepted selecting operation, to generate a composite image; hold the composite image as a new history image; combine the new history image and a third captured image by writing the third captured image over the history image, at least one of which has been transformed, to generate a new composite image, the third captured image being positioned subsequent to the second captured image along the time axis of the captured moving image; output the composite image and the new composite image; and sequentially display the composite image and the new composite image.
