A vehicle image processing apparatus comprising: image acquisition means for acquiring a captured image which is an image that has captured an area around a vehicle with the use of at least one camera; projection conversion means for converting the captured image into an image viewed along a virtual line of sight that is a line of sight running from a predetermined position in a predetermined direction either with the use of a projection map which at least holds the relationship between the position of a pixel of the captured image and the position of a pixel of an image viewed along the virtual line of sight, or using at least one predetermined projection shape, which is a three-dimensional shape; line-of-sight change detection means for detecting whether a first virtual line of sight which is a predetermined virtual line of sight is switched to a second virtual line of sight which is a different virtual line of sight from the first virtual line of sight; line-of-sight parameter generation means for acquiring at least a parameter value that is the visual point position or the viewing direction for each of the first and second virtual lines of sight after detecting that the first virtual line of sight is switched to the second virtual line of sight, and generating a parameter value that is gradually changed from the parameter value of the first virtual line of sight to the parameter value of the second virtual line of sight; and changed image generation means for generating, on the basis of the gradually changed parameter value, at least one changed image which is an image that is gradually changed from a first image, which is an image viewed along the first virtual line of sight and converted using the projection map, to a second image, which is an image viewed along the second virtual line of sight and converted using the projection map, the changed image being generated using the predetermined projection shape; wherein the line-of-sight change detection means detects that the first virtual line of sight is switched to the second virtual line of sight if the difference between the unchanged and changed parameter values for either the visual point position or the viewing direction is greater than or equal to a specified value. image acquisition means for acquiring a captured image which is an image that has captured an area around a vehicle with the use of at least one camera; projection conversion means for converting the captured image into an image viewed along a virtual line of sight that is a line of sight running from a predetermined position in a predetermined direction either with the use of a projection map which at least holds the relationship between the position of a pixel of the captured image and the position of a pixel of an image viewed along the virtual line of sight, or using at least one predetermined projection shape, which is a three-dimensional shape; line-of-sight change detection means for detecting whether a first virtual line of sight which is a predetermined virtual line of sight is switched to a second virtual line of sight which is a different virtual line of sight from the first virtual line of sight; line-of-sight parameter generation means for acquiring at least a parameter value that is the visual point position or the viewing direction for each of the first and second virtual lines of sight after detecting that the first virtual line of sight is switched to the second virtual line of sight, and generating a parameter value that is gradually changed from the parameter value of the first virtual line of sight to the parameter value of the second virtual line of sight; and changed image generation means for generating, on the basis of the gradually changed parameter value, at least one changed image which is an image that is gradually changed from a first image, which is an image viewed along the first virtual line of sight and converted using the projection map, to a second image, which is an image viewed along the second virtual line of sight and converted using the projection map, the changed image being generated using the predetermined projection shape; wherein the line-of-sight change detection means detects that the first virtual line of sight is switched to the second virtual line of sight if the difference between the unchanged and changed parameter values for either the visual point position or the viewing direction is greater than or equal to a specified value.
