PROBLEM TO BE SOLVED: To adjust an adjustment value of inclination correction or the like with high accuracy about an image having distortion obtained by using an ultra wide visual field optical system, such as a fisheye lens.SOLUTION: A first conversion part 101 performs first geometric conversion for suppressing distortion of a first image signal to acquire a second image signal. A second conversion part 102 respectively displays images corresponding to third and fourth image signals obtained by performing second geometric conversion different from the first geometric conversion on a display part 103 in accordance with adjustment values preset in the second and first image signals. Then, the adjustment values are adjusted in accordance with an image displayed in the display part. |
