Provided are an image-processing system, an image-processing device, an image-processing method, and an image-processing program capable of appropriately inspecting, measuring, or recognizing targets by using a plurality of imaging units even in a case where there is an individual difference in performance of each imaging unit. An image correction-processing unit that individually acquires pieces of image data from a first camera and a second camera to individually correct image deterioration caused by each of the cameras by pieces of image-processing and an inspection processing unit that individually acquires the pieces of image data after the correction from the image correction-processing unit to individually inspect imaged targets by pieces of image-processing are provided. In a case where the first camera and the second camera image the same targets, the image correction-processing unit individually corrects the image data acquired from each camera such that inspection results match within a desired range.

Image processing system, image processing device, image processing method, and image processing program

Provided an imaging system, an imaging apparatus and an image processing apparatus constituting the imaging system, an image processing method used in the image processing apparatus, and a non-transitory recording medium for causing a computer to implement the image processing method. According to the imaging apparatus according to one aspect of the present invention, an image of high image quality can be acquired (reconstructed) in the imaging system configured to include the imaging apparatus by acquiring first and second projected images using Fresnel zone plates having different phases of local spatial frequencies. In addition, the design parameters (pitches and the areas of the Fresnel zone plates, the number of pixels of image sensors, a distance between the Fresnel zone plates and the image sensors, and the like) can be selected without considering an effect of a noise component, and the number of restrictions on the design parameters is small.

Image processing apparatus and image processing method that generate a complex image based on a Fresnel Zone pattern

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.

Image processing device, image processing method, and camera system

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.
