When an A/D-converted composite video signal is directly outputted while a system clock frequency is switched so as to execute the determination of a signal system, a digital chroma demodulation system prevents the images displayed by the composite video signals from distorting in accordance with switching of frequency of system clock. As for a frequency m (=fsc×n) of system clock synchronizing with a color burst signal, a frequency m of system clock between systems is set to fall in a predetermined range by changing a coefficient n in accordance with a system (a color bust signal frequency). Thus, since a composite video signal is A/D-converted in accordance with a substantially constant sampling frequency, the sampling condition such as a sampling frequency and a sampling point is not greatly changed.

A display device comprising a CRT having a reduced number of components for automatic cutoff adjustment. The device needs an IC having a less number of connection pins. The device adds reference pulses to given portions within every field of video signals. The resulting cathode currents are converted into voltage pulses. These voltage pulses are compared with a reference voltage by a comparator. The output signal from this comparator is counted by forward-backward counters for three primary colors, respectively, and converted into analog form. Level shift circuits for the three primary colors, respectively, control the DC components of the video signals according to the output signals from the D/A converters. In this way, the cutoff characteristics of the CRT are controlled.

Oscillation circuit that generates an oscillating signal by charging and discharging a capacitor between two reference voltages employs several constant current sources, with the number of constant current sources that are connected to the capacitor at any one time being controlled so that the oscillation frequency can be changed in a step-wise fashion, whereby the circuitry is relatively simplified compared with known step-wise changing oscillators.
