ABSTRACT:
A color signal converting circuit which is simplified in circuit construction and is high in operating speed. The color signal converting circuit has a plurality of input terminals and a plurality of output terminals and comprises only a plurality of addition/subtraction operators for dealing with signals all in the form of integral numbers and for converting signals of a first color signal system received by way of the input terminals into signals of a second color signal system in accordance with conversion expressions each including only 2.sup.-n (n is an integer) as a coefficient. The signals obtained from the addition/subtraction operators are outputted from the output terminals.
