    摘要: 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.

    摘要: A video signal processing circuit is incorporated in an IC for camcorder in which a camera signal outputted from a CCD image sensor is processed in a digital manner such that luminance and color signals can be outputted. In the IC, a vertical interpolation circuit produces two kinds of vertically interpolated data on the basis of a digital camera signal of one channel within an image area being set by an electronic zoom function. A YC separation circuit receives the two kinds of vertically interpolated data, and an output of the YC separation circuit is applied a horizontal interpolation circuit or an RGB composition circuit. If the YC separation output is applied to the horizontal interpolation circuit, the same outputs two kinds of horizontally interpolated data upon which three primary color signals are composed by the RGB composition circuit. If the YC separation output is applied to the RGB composition circuit, the horizontal interpolation circuit produces two kinds of horizontally interpolated data on the basis of three primary color data outputted by the RGB composition circuit.
