PROBLEM TO BE SOLVED: To provide an image processor provided with the function for correcting trapezoidal distortion through simple operation. SOLUTION: This processor corrects the distortion caused in an image when there is inclination between the optical axis of a lens and an object. In this case, the processor is provided with a correcting means 10 for calculating the respective correction parameters of a correction parameter for correcting a horizontal expansion magnification corresponding to the horizontal distortion amount of the image, a correction parameter for correcting a vertical expansion magnification corresponding to the vertical distortion amount of the image, a correction parameter for correcting the vertical central axis of the image and a correction parameter for correcting the angle of the image in rotating direction and executing the correction of image data based on these correction parameters. |
