Patent ID: 8675070

Claim:
A driving support device, comprising: an imaging unit for capturing images of a vicinity of a vehicle; an overhead image creating unit for creating an overhead image of an area including a position of the vehicle based on the images captured by the imaging unit; a recording unit for recording image data of the overhead image created by the overhead image creating unit; a movement status determining unit for acquiring movement information relating to movement of the vehicle and determining a movement status of the vehicle based on the acquired movement information; a composite image creating unit for, based on (i) the movement status determined by the movement status determining unit and (ii) a parameter associated with the movement status, compositing the image data of the overhead image recorded in the recording unit and creating a composite image of the area including the position of the vehicle; a displaying unit for displaying the composite image created by the composite image creating unit; and a calibrating unit for calibrating the parameter based on (a) a position of a reference marker included in the composite image created by the composite image creating unit according to the movement status and (b) a predicted position of the reference marker superimposed and displayed on the composite image according to the movement status, wherein the movement status includes a turn made by the vehicle; the parameter associated with the movement status includes a turn parameter being used by the composite image creating unit for creating the composite image; and the calibrating unit is configured for calibrating the turn parameter based on (a) the position of the reference marker included in the composite image that the composite image creating unit created according to the turn and (b) the predicted position of the reference marker superimposed and displayed on the composite image according to the turn.
