To provide a digital camera which can correct a formed image within the digital camera immediately the image is formed and which utilizes easy calculation formulae and reduces the number of times of calculations for correction, so as to provide least load to be borne by not only the digital camera but also the photographer, there is provided a digital camera having an imaging unit, a display unit, a main control unit, a distortion correction unit, a main storage unit, and an auxiliary storage unit, the distortion correcting unit including a contour retrieval module, an image correction module and a correction control module, the contour retrieval module including a pixel number conversion module, a color space conversion module, a dividing module, a straight line retrieval module and a contour straight line selection module, the image correction module including an intersection point calculation module, a geometric projective conversion formula calculation module, a trimming module and a resize module, an integerizing module, a coordinate transformation module and a pixel interpolation module.
