1. A road sign recognition apparatus comprising:
- an image generation unit that generates a synthetic image so that a plurality of images an in-vehicle camera captured are respectively transformed to images downwardly viewing from a vertical direction and are connected to one another in time-series order; and
an identification unit that identifies types of road signs contained in the synthetic image in a manner that a quantity of features of the synthetic image is extracted and compared to a preliminarily provided template.
