1. A traffic light recognition-based smart cruise control (SCC) control apparatus comprises:
an image-capturing unit configured to capture a front-side image of a vehicle; and
a controller configured to classify at least one traffic light in the front-side image, calculate a distance to each classified traffic light, determine that there are a plurality of traffic lights having different distances in the front-side image, recognize, in response to the determining, a first signal of a first traffic light closest to the vehicle and a second signal of a second traffic light located next to the first traffic light, determine that the first signal is a driving signal and the second signal is a stop signal, calculate, in response to the second determining step, an acceleration time, and control the vehicle to be accelerated and traveled during the acceleration time, and stopped before the second traffic light by using frictional force.
