Abstract

A picture processing apparatus is composed of an infrared ray sensor for producing an infrared picture in which a heat distribution of a measured area is recorded, a picture processing section for processing the infrared picture to extract pieces of personal characteristic data and environmental characteristic data from the infrared picture, and a picture information detecting section composed of a neural network for detecting pieces of personal information and environmental information according to the characteristic data. To be concrete, one or more human-areas respectively recording one or more persons are picked out from the infrared picture, and representative points of the human-areas, the number of human-areas, the number of pixels in each of the human-areas and shapes of the human-areas are extracted as the personal characteristic data. Also, the number of persons in each of the human-areas, foot positions of the persons, person's postures, skin temperatures of the persons and the volume of person's clothes are detected as the personal information according to the personal and environmental characteristic data.
