A vehicle image processing apparatus includes: a group of cameras; a drawing unit that converts a captured image into an image viewed along a line of sight running from a predetermined position in a predetermined direction; a viewing-line-of-sight changing unit that detects whether a first line of sight is switched to a second line of sight; and a viewing-line-of-sight generation/updating unit that acquires parameters concerning the first and second lines of sight after detecting the switching and generates a parameter which is gradually changed from the parameter of the first line of sight to the parameter of the second line of sight. Moreover, the drawing unit generates, on the basis of the gradually changed parameter, an image which is gradually changed from an image viewed along the first line of sight to an image viewed along the second line of sight.
