摘要： Disclosed herein is an image processing apparatus including, a distortion correction processor for generating a distortion-corrected output image from a distorted wide-field-of-view image, and a selected area setting unit for setting a selected area in the output image, wherein the distortion correction processor corrects a distortion with a lower image quality when an output image of an area exclusive of the selected area is generated than when an output image of the selected area is generated.

摘要： A lens barrel rotation detection apparatus for detecting a rotational state of a lens barrel to which a lens for image pickup is attached and which is rotated in a horizontal direction or a vertical direction by driving force of a driving section, includes: a single rotatable member rotatable together with rotation of the lens barrel; and three rotation detection section for detecting a rotational state of the rotatable member. The rotatable member has a fixed pattern formed thereon so as to be detected by said rotation detection section and a rotation limit section indicative of limit positions of a range of rotation of the lens barrel. The rotation detection section is disposed for detection of presence or absence of rotation of the rotatable member and the limit positions of the range of rotation.
