Title: IMAGE PROCESSING DEVICE, IMAGING SYSTEM, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM
Abstract:
The purpose of the present invention is to provide an image processing device, an imaging system, an image processing method, and a recording medium which allow a clear image with a wide angle of view to be obtained without using a lens. The image processing device according to one aspect of the present invention is provided with: a projection image input unit that receives input of a projection image formed by light from a subject entering a Fresnel zone plate; a complex image generation unit that generates a complex image including an image of a real part and an image of an imaginary part by multiplying, with the projection image, a first Fresnel zone pattern and a second Fresnel zone pattern which has the same local spatial frequency in each area as the first Fresnel zone pattern, the phase of the local spatial frequency being different from that of the local spatial frequency of the first Fresnel zone pattern; and a Fourier transform unit that reconstructs a spatial area image by performing two-dimensional complex Fourier transform on the complex image.
