Image processing device, image processing method, and program

An image processing device comprising:

• an image input unit that receives, as inputs, a plurality of images captured by a plurality of cameras;
• a first scaling processing unit that performs scaling processing on at least one image of two images to be combined with each other among the plurality of images in a direction perpendicular to a direction in which the two images are combined;
• a second scaling processing unit that performs the scaling processing on a partial image including an image of a combined portion, at which the two images are combined with each other, of at least the one image of the two images in the direction in which the two images are combined;
• and
• a combination image generation unit that combines the plurality of images after the scaling processing using the first scaling processing unit and the second scaling processing unit, and generates a continuous combination image,
• wherein the first scaling processing unit performs the scaling processing on at least the one image of the two images according to a first predetermined scaling ratio, and suppresses a misalignment on the image of the combined portion of the two images to be combined with each other in the perpendicular direction, and
• the second scaling processing unit performs the scaling processing on the partial image according to a second predetermined scaling ratio, suppresses a misalignment or distortion on the image of the combined portion of the two images to be combined with each other, and causes the image to be continuous in the combination direction.

A non-transitory computer readable recording medium storing a program causing a computer to perform:
