<p>A color signal converting circuit, which is simplified in circuit construction and has a high operating speed, has a plurality of input terminals (1, 2, 3) and a plurality of output terminals (9, 10, 11) and comprises a plurality of addition/subtraction operators (4-8) for dealing with signals all in the form of integral numbers and for converting signals (RGB) of a first color signal system received by way of the input terminals into signals of a second color signal system (Y, I, Q) in accordance with conversion expressions each including only 2<-n> (n is an integer) as a coefficient. The signals obtained form the addition/subtraction operators (4-8) are outputted from the output terminals. <IMAGE></p> |
