Abstract:
1. An image processing apparatus that processes image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, the image processing apparatus comprising: a region selection mode setting section that selectively sets a first region selection mode in which, from a field of view represented by the image data a selected region is selected which indicates a partial region of the field of view by using an orthogonal coordinate system and a second region selection mode in which, from the field of view represented by the image data, the selected region is selected which indicates the partial region of the field of view by using a polar coordinate system; and a data output section that outputs distortion-corrected data obtained by correcting the distortion in the image data that corresponds to the selected region selected in the first or second region selection mode which is set by the region selection mode setting section, wherein the region selection mode setting section switches from the first region setting mode to the second region setting mode according to whether or not the angle exceeds a first threshold value and switches from the second region selection mode to the first region selection mode according to whether or not the angle exceeds a second threshold value that is different from the first threshold value.
