ABSTRACT:
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.
