    摘要： A signal processing circuit is utilized in a video camera which includes a CCD having pixels arranged in a dot-matrix fashion and color filters of R, G and B arranged in a mosaic fashion, and an output signal from the CCD is converted into a digital signal. A horizontal aperture signal (Hap) and a vertical aperture signal (Vap), which are produced on the basis of the digital signal, are multiplied by coefficients (K1, K2) which are obtained on the basis of a horizontal correlation value (Sh) and a vertical correlation value (Sv), and then, added to each other in an adding circuit, whereby an aperture signal is obtained by the adding circuit. The aperture signal is added to a luminance signal to perform an image enhancement.

    摘要： A color video camera includes a CCD, and digital signals of 4 lines produced on the basis of an outputs from the CCD are applied to a selection circuit which selectively outputs digital signals of 3 lines. A horizontal interpolation circuit and a vertical interpolation circuit perform interpolation calculation on the basis of the digital signals, and outputs a plurality of horizontal color signals and a plurality of vertical color signals, respectively. A horizontal correlation detection circuit and a vertical correlation detection circuit evaluate a horizontal correlation value and a vertical correlation value of a specific pixel with respect to pixels around the specific pixel. Horizontal and vertical weighing coefficients are calculated by a coefficient calculation circuit in accordance with the correlation values, and the coefficients are applied to a weighted addition circuit which adds the horizontal color signals and the vertical color signals to each other for each color in accordance with the coefficients, and outputs the color signals of the specific pixel.

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.
