Imaging apparatus with cylindrical lenses

A imaging apparatus comprising:

• an image sensor configured to convert light received by a plurality of pixels arranged in an array on a light receiving surface into an electrical signal and output the electrical signal;
• an optical element arranged on a side closer to the light receiving surface of the image sensor and being configured to transmit the light;
• and
• an image processing circuitry configured to perform image processing of the electrical signal output from the image sensor,
• wherein a plurality of concentric cylindrical lenses are formed on one surface of the optical element, and each lens of the plurality of concentric cylindrical lenses is formed with a cylindrical surface, and each lens has a curvature of a convex lens in the vertical direction of the optical element and no curvature in the horizontal direction of the optical element, and the plurality of concentric cylindrical lenses are configured to concentrate incident light,
• wherein the image sensor receives the light concentrated by the cylindrical lenses and outputs an image signal that includes an image gathered cylindrically, and
• wherein the image processing circuitry is configured to:
• input the image signal that includes the image gathered cylindrically output from the image sensor,
• generate a moire fringe image when the image gathered cylindrically included in the image signal combines with another concentric image, and
• perform processing including a two-dimensional Fourier transform on the moire fringe image, and generate an image.
