A three-dimensional object imaging device comprises a compound-eye imaging unit and an image reconstructing unit for reconstructing an image of a three-dimensional object based on multiple unit images captured by the imaging unit. Based on the unit images obtained by the imaging unit, the image reconstructing unit calculates a distance (hereafter “pixel distance”) between the object and the imaging unit for each pixel forming the unit images, and rearranges the unit images pixel-by-pixel on a plane at the pixel distance to create a reconstructed image. Preferably, the image reconstructing unit sums a high-frequency component reconstructed image created from the multiple unit images with a lower noise low-frequency component unit image selected from low-frequency component unit images created from the multiple unit images so as to form a reconstructed image of the three-dimensional object. This makes it possible to obtain a reconstructed image with high definition easily by a simple process.

An imaginary object plane is set in front of an imaging device body (plane setting step). A part of optical conditions of optical lenses are changed as variables, and positions of points (pixel observation points) on the imaginary object plane where lights coming from pixels of a solid-state imaging element and back-projected through the optical lenses are calculated (pixel observation point calculating step). The dispersion in position of the calculated pixel observation points is evaluated (evaluating step). Finally, a set of values of the variables giving maximum evaluated dispersion of the calculated pixel observation points is determined as optimum optical condition of the optical lenses (condition determining step). This reduces the number of pixels which image the same portions of the target object, making it possible to reduce portions of the same image information in multiple unit images, and to stably obtain a reconstructed image having a high definition.
