A person detection apparatus determines a weather condition such as rain and solar radiation based on a variety of information from a weather information input portion. Then, based on a determination result of the weather condition, the umbrella ratio showing the ratio of persons with umbrellas is calculated. The person detection apparatus uses a no-umbrella recognition model describing a person with no umbrella and an umbrella-hold recognition model describing a person with umbrella in order to perform pattern recognition to an input image to derive recognition scores based on the respective recognition models. Then, the umbrella ratio depending on the weather condition is used to correct the respective recognition scores based on the pattern recognition using the no-umbrella model and the recognition score based on the pattern recognition using the umbrella-hold model; the corrected recognition scores are output as a final detection result.
