1. An image processing apparatus that processes an image, the image processing apparatus comprising: an image processor configured to: receive a captured image from an image acquisition part that acquires the captured image from a camera that captures an image of a vicinity of a vehicle; project data of the captured image onto a virtual projection plane provided in the vicinity of the vehicle; and correct deformation of the captured image caused by projection of the captured image onto the virtual projection plane, wherein: in a case of presence of input of a command indicative of enlarging a portion of the captured image, the image processor corrects the deformation of the captured image by using a greater correction amount than a correction amount that is used in a case of absence of the input of the command indicative of enlarging the portion of the captured image, the image processor corrects the deformation of the captured image by use of a correction amount as long as an undisplayed area does not overlap an enlargement region that is enlarged by the input of the command indicative of enlarging the portion of the captured image, the undisplayed area being caused by correction of the deformation, and the correction of the deformation is such that a greater correction amount is used for image data to be displayed on an upper portion of a screen, among the image data projected onto a surface of a road.
