An object distance deriving device comprises a compound-eye imaging unit for capturing n unit images and a microprocessor for calculating an object distance of an object from the imaging unit based on the unit images. The microprocessor sets a first temporary distance D1 from discrete temporary distances D1-Dn prepared in advance, and rearranges pixels of each unit image at D1 to create one reconstructed image. The microprocessor reversely projects the pixels of each unit image at D1 to create n reverse projection images. The microprocessor calculates and sums n deviations each between a pixel of the reconstructed image and that of each reverse projection image at each xy coordinate position to calculate an evaluation value for D1. The microprocessor repeats this process for the temporary distances D2-Dn to obtain n evaluation values. The microprocessor determines one of the temporary distances D1-Dn giving a minimum evaluation value as the object distance.
