Title:
IMAGING DEVICE, IMAGE PROCESSING DEVICE, IMAGING SYSTEM, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/221025
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an imaging system that is able to acquire a high-quality image without using a lens, and has few restrictions on design parameters, an imaging device and an image processing device that constitute the imaging system, an image processing method used in the image processing device, and a recording medium for causing a computer to implement the image processing method. An imaging device according to one embodiment of the present invention can acquire (reconstruct) a high-quality image in an imaging system configured to include the imaging device by acquiring first and second projected images using a Fresnel zone plate having different phases of local spatial frequencies. Further, design parameters (the pitch and area of the Fresnel zone plate, the number of pixels of an image sensor, the distance between the Fresnel zone plate and the image sensor, and the like) can be selected without consideration for the influence of a noise component, and there are few restrictions on the design parameters.
