A calibrator for cameras includes a controlling circuit, a photographing circuit, a calculating circuit, and an instructing circuit. The controlling circuit is configured to control a movable body in a shooting area of the cameras. A marker is provided on the movable body for calibration of the cameras. The photographing circuit is configured to control the cameras to photograph the marker at a first position at a first timing to generate first images. The photographing circuit is configured to control the cameras to photograph the marker at a second position at a second timing to generate second images. The calculating circuit is configured to calculate parameters of the cameras based on the first images and the second images. The instructing circuit is configured to transmit the parameters to the cameras to calibrate the cameras.

This image generation method is for generating a virtual image by a processor using at least one of images obtained by cameras disposed in different positions and attitudes capturing the same target space in a three-dimensional (3D) space. The virtual image is a two-dimensional (2D) image of the target space viewed from a virtual viewpoint in the 3D space. When generating the virtual image using one or more second images captured by one or more second cameras, at least one of which is different from one or more first cameras that capture one or more first images serving as a basis among the images, a second process which includes at least one of luminance and color adjustments and is different from a first process performed to generate the virtual image using the one or more first images is performed on the one or more second images.

A free-viewpoint video generating method includes obtaining a multi-viewpoint video including N videos of N viewpoints (N being an integer greater than 1), and generating a free-viewpoint video of a virtual viewpoint based on the multi-viewpoint video such that the free-viewpoint video shows target areas and has a first resolution higher than each of resolutions of the N videos, the virtual viewpoint being different from the N viewpoints. For each target area, the generating includes: referring to a three-dimensional model generated based on the N videos to specify N reference areas which are shown by the N videos and which correspond to the each target area in the free-viewpoint video; and calculating components of pixels to represent the each target area in the free-viewpoint video, based on components of pixels to represent the N reference areas in the N videos.
