Abstract
An apparatus for identifying the state of lighting includes a processor configured to identify the states of lighting of a first lighting part and a second lighting part of a vehicle by inputting time-series images representing the vehicle into a classifier. The classifier includes a feature calculation part configured to calculate a feature map whenever one of the time-series images is inputted in chronological order; a first state-of-lighting identification part including a recursive structure and configured to identify the state of lighting of the first lighting part while updating a first internal state by inputting the feature map calculated for each of the time-series images in chronological order; and a second state-of-lighting identification part including a recursive structure and configured to identify the state of lighting of the second lighting part while updating a second internal state by inputting the feature map in chronological order.
