Abstract

PURPOSE:To discriminate a static body from a man, and to measure its distance, by storing in advance the static body positioned in the circumference of a television set. CONSTITUTION:A data of a memory circuit 37 which has stored in advance a position of a static body position in the circumference of a television set 21 is compared with a data which has sampled a position of the circumferential body in order and has A/D-converted 49, and a position of a man is decided 63. Also, a malfunction for measuring a destance is reduced by providing a threshold level adding circuit 65 and giving allowance to the data stored in the memory circuit 37. According to this constitution, it is possible to exactly measure a distance between a man and a television set by exactly discriminating only the man, irrespective of existance of the static body.
