An image processing apparatus comprising: a wide angle camera that is arranged at a position deviated from a vehicle center line (Lc) that is a center line of a vehicle in a longitudinal direction, the wide angle camera capturing an image and increasing a degree of size reduction of an object as being farther from a center of the captured image (Gs) a control circuit that extracts as a display image a part of the image captured; a display portion that displays the display image extracted by the control circuit to an occupant of the vehicle; and a distortion correction portion that performs a distortion correction of the captured image; wherein: the control circuit includes an extraction determination portion (S120 to S160) that determines an extraction position of the display image in the captured image according to (i) a center position of the display image to the vehicle center line and (ii) the degree of size reduction of the object, the degree of size reduction being represented at a pixel of a specific position in the display image; and the extraction determination portion (S120 to S160) determines the extraction position, so that the center position of the display image is located to the vehicle center line (Lc) as close as possible, and the degree of size reduction of the object represented at the pixel of the specific position is equal to or less than a first predetermined value. a wide angle camera that is arranged at a position deviated from a vehicle center line (Lc) that is a center line of a vehicle in a longitudinal direction, the wide angle camera capturing an image and increasing a degree of size reduction of an object as being farther from a center of the captured image (Gs) a control circuit that extracts as a display image a part of the image captured; a display portion that displays the display image extracted by the control circuit to an occupant of the vehicle; and a distortion correction portion that performs a distortion correction of the captured image; wherein: the control circuit includes an extraction determination portion (S120 to S160) that determines an extraction position of the display image in the captured image according to (i) a center position of the display image to the vehicle center line and (ii) the degree of size reduction of the object, the degree of size reduction being represented at a pixel of a specific position in the display image; and the extraction determination portion (S120 to S160) determines the extraction position, so that the center position of the display image is located to the vehicle center line (Lc) as close as possible, and the degree of size reduction of the object represented at the pixel of the specific position is equal to or less than a first predetermined value. the control circuit includes an extraction determination portion (S120 to S160) that determines an extraction position of the display image in the captured image according to (i) a center position of the display image to the vehicle center line and (ii) the degree of size reduction of the object, the degree of size reduction being represented at a pixel of a specific position in the display image; and the extraction determination portion (S120 to S160) determines the extraction position, so that the center position of the display image is located to the vehicle center line (Lc) as close as possible, and the degree of size reduction of the object represented at the pixel of the specific position is equal to or less than a first predetermined value.
