<p>In a white balance control in which correction signals are added to input chrominance signals (Uin, Vin) to obtain output chrominance signals (Uout, Vout), chrominance sum signals are furnished (A1) from chrominance signals (Uin, Vin; Uout, Vout) and reference chrominance signals (Uref, Vref), exponential signals are derived (E) from the chrominance sum signals, and the reference chrominance signals (Uref, Vref) are multiplied (M1) by the exponential signals to obtain the correction signals.</p> |
