PROBLEM TO BE SOLVED: To improve image quality by correcting image quality deterioration specific for an imaging apparatus including an optical system having a structure with periodicity.SOLUTION: An image processing apparatus includes an acquisition unit, a filter setting unit and a filtering processor. The acquisition unit acquires first image data from an imaging apparatus that photographs an erect image formed by respective refractive index distributed lenses in a lens array where a plurality of refractive index distributed lenses are arrayed, using a line sensor in which a plurality of light-receiving elements are arrayed. The filter setting unit determines a sharpening filter to be applied to pixels of the first image data corresponding to the respective light-receiving elements, according to remainder values obtained respectively by dividing positions of the light-receiving elements on the line sensor by an interval of a lens arrangement of the lens array. The filtering processor generates second image data by applying the determined sharpening filter to the respective pixels of the first image data. |
