Driving support device, driving support method, and driving support program

A driving support device, comprising:

• an imaging unit for capturing images of a vicinity of a vehicle;
• a recording unit for recording image data of the images captured by the imaging 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 recorded in the recording unit and creating a composite image of an area including a 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 that the composite image creating unit created 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.
