IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

An image processing apparatus that obtains a synthesized image of a subject viewed from an arbitrary viewpoint includes a calculator, a storage, and a synthesizer. The calculator calculates a correction value for a pixel value of a pixel that partially constitutes the picked-up images on the basis of a brightness of each of the plurality of picked-up images. The storage stores the correction value for each of the pixels. The synthesizer obtains a pixel value of a pixel in the synthesized image that corresponds to the pixel that partially constitutes the picked-up images by correcting a pixel value of the pixel that partially constitutes the picked-up images on the basis of a positional relationship of the pixel in the picked-up images, a correspondence relationship between the picked-up images and the synthesized image, and the correction value, and thereby generates the synthesized image.

主权项

1. An image processing apparatus that generates a synthesized image of a subject viewed from an arbitrary viewpoint from a plurality of picked-up images obtained by picking up images of surroundings of the subject in different directions, the image processing apparatus comprising
a computer which includes a processor that performs a process including:
a calculation process that calculates a correction value for a pixel value of a pixel that partially constitutes the picked-up images on the basis of a brightness of each of the plurality of picked-up images;a storage process that stores to a storage of the computer the correction value calculated by the calculation process for each of the pixels; anda synthesization process that corrects a pixel value of the pixel that partially constitutes the picked-up images on the basis of a positional relationship of the pixel in the picked-up images, a correspondence relationship between the picked-up images and the synthesized image, and the correction value stored in the storage to obtain a pixel value of a pixel in the synthesized image that corresponds to the pixel that partially constitutes the picked-up images, and thereby generates the synthesized image.
