Document Type and Number:
Japanese Patent JPH0795856
Kind Code:
B2
Abstract:
A digital video camera includes a pseudo-saturation calculating circuit by which a pseudo-saturation corresponding to an actual saturation is calculated on the basis of two color difference signals, and a suppression coefficient is calculated by a suppression coefficient calculating circuit on the basis of the pseudo-saturation. Each of the color difference signals are outputted by a selecting circuit in a dot sequential manner, and multiplied by the suppression coefficient in a multiplying circuit. Therefore, a signal in which a low-saturation chrominance signal is outputted from the multiplying circuit, whereby the low-saturation chrominance signal can be suppressed even though a sampling frequency is not increased.
