PURPOSE: To perform an automatic air conditioning operation which is adapted for an individual's preference by a method wherein an image information of each of the air conditioned individual and an air conditioning operating information corresponding to each of the air conditioned individual are stored, these stored information are collated, an air conditioning operation information corresponding to the image information is outputted and controlled.

CONSTITUTION: An information memory means 4 and an information outputting means 5 are connected to an image means 2 through a mode changing-over switch 3. An operation control circuit 6 acting as an operation control means is connected to the information outputting means 5. The image means 2 outputs an image information of a dweller and is provided with an image pick-up device 21 composed of a CCD element. When a mode changing-over switch 3 is changed over to an air conditioner operation mode, the image signal of the image memory 24 is inputted to the information outputting means 5 and when the mode changing-over switch 3 is changed over to a registration mode, the image signal of the image memory is inputted to an information memory means 4. The information outputting means 5 is composed of a collating circuit 51, a mode selection circuit 52 and a calculation circuit 53. The calculation circuit 53 receives a plurality of control data signals from the mode selection circuit 52, calculates a mean air conditioning control data and outputs the control data signals.
