Abstract: Provided are an imaging apparatus, an image processing apparatus, an image processing method, and a non-transitory computer readable recording medium storing an image processing program capable of appropriately correcting both of focus breathing and distortion. Focus breathing is corrected by subjecting image data to magnification/reduction processing according to a magnification/reduction rate determined for each focus position. Distortion is corrected through image processing to the image data with focus breathing corrected. In correcting distortion, distortion appearing in image data after correction of focus breathing is corrected.

Abstract: An image processing device includes a transfer function input unit to which each of transfer functions of a plurality of imaging systems is input, a calculation unit that calculates a target resolution value which is a target value of recovery processing that recovers a plurality of captured images to be output from each of the plurality of the imaging systems based on the input transfer functions and a predetermined criterion, a recovery-filter generation unit that generates a recovery-filter used for the recovery processing with respect to each of the plurality of imaging systems based on the transfer functions of the plurality of imaging systems and a target resolution value, and a recovered image generation unit that performs the recovery processing with respect to the captured images acquired from the plurality of imaging systems by using the recovery-filter generated for each of the plurality of imaging systems to generate recovered images.

Abstract: Provided are an image processing device, an image processing method, and a non-transitory computer readable recording medium storing a program which generate a favorable-quality combination image of which distortion is partially corrected with no calculation cost. A plurality of images captured by a plurality of cameras is input, and scaling processing is performed 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 continuous combination image is generated by combining the plurality of images after the scaling processing. The scaling processing is performed on at least the one image of the two images according to a predetermined scaling ratio, and a misalignment on an image of a combined portion of the two images to be combined with each other in the perpendicular direction is suppressed.
