摘要

PROBLEM TO BE SOLVED: To provide a travel support device that appropriately controls a timing for switching imaging data in which the front side and rear side of a vehicle is photographed.SOLUTION: An on-vehicle device 10 includes an input part 100, processing unit 110, navigation part 120, in-vehicle bus I/F 140, and display part 150. The processing unit 110 includes a selection part that receives input of imaging data D1 from a front camera installed on the front side of a vehicle and imaging data D2 from a rear camera installed on the rear side of the vehicle and selects either one of the pieces of imaging data on the basis of a selection signal from the control part 180. The control part 180 determines which image data to select on the basis of the number lanes on the road on which the vehicle is traveling.SELECTED DRAWING: Figure 2
