Document Type and Number:
Japanese Patent JP6825458
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image processing device capable of improving access efficiency to a memory by embedding information related to an amount of correction into any vignetting region of a plurality of images, a photographing device, and an image processing method.SOLUTION: A photographing device comprises two imaging elements, an image processing device, and an external memory. An image processing device comprises an image processing unit, an amount-of-correction creation unit, an image correction unit, a projective transformation unit, an image output unit, a CPU, and an external memory. The amount-of-correction creation unit comprises a correction target determination unit, an amount-of-correction calculation unit, a correction map creation unit, and an embedding unit. The correction target determination unit determines a correction target image from a plurality of images on the basis of a pixel vale of each pixel of the plurality of images. The amount-of-correction calculation unit calculates an amount of correction for correcting the correction target image on the basis of a pixel value of each image. The correction map creation unit creates a correction map (M4) for correcting the correction target image. The embedding unit embeds information related to the amount of correction such as data of the correction map (M4) into any vignetting region of the plurality of images.SELECTED DRAWING: Figure 9
