Abstract
In an apparatus and a process for obtaining image signals, and electronically mixing the image signals to generate mixed signals, the steps include modulating one of the image signals with the control signal, amplitude-inverting the control signal, modulating the other image signal with the amplitude-inverted control signal, and adding a modulated image signal so as to obtain the mixed signal. The control signal has prearranged characteristics determining the commencement and at least partly the characteristic of the modulating step.
