Abstract

PURPOSE:To measure the distance accurately by memorizing a stationary object around a television receiver beforehand, and judging only a man regardless of the presence of the stationary objects. CONSTITUTION:In a judging circuit 37, the contents of a memory circuit 35, wherein the state of the presence of the stationary objects is stored, are compared with the contents of a memory circuit 36 for every corresponding address. Thus the distance between the man and the television receiver is measured. When the contents of the memory circuit 36 is compared with the contents of the memory circuit 35, and the contents of the address are different, the data inputted in the earlier address in the sequence in the memory circuit 36 is the sampling data of the reflected wave from the man.
