<P>PROBLEM TO BE SOLVED: To prevent coloring in the periphery of an overexposed image and to prevent its display. Ž<P>SOLUTION: An imaging apparatus 10 extracts signals of primary colors at a plurality of positions around a predetermined pixel position from an image signal obtained by an imaging device in which color filters of primary colors of R, G and B are alternately arranged on a plurality of pixels that are two-dimensionally arranged in a predetermined array, and interpolates the signals at the predetermined pixel position. At that time, a neighboring overexposure detecting part 11 determines that a pixel under consideration is included in the periphery of overexposure when the level of peripheral pixels arranged in a neighborhood being within a predetermined range to the pixel under consideration included in an image composed of RGB signals exceeds a predetermined threshold. A clip level generating part 12 generates a clip level for suppressing the level of the pixel under consideration in accordance with the change amount of the levels of the pixel under consideration and the peripheral pixels. A suppression processing part 13 suppresses the level of the pixel under consideration and suppresses chromatic aberration that occurs in the pixel under consideration on the basis of the change amount of the levels and the clip level.
