Abstract
In an image pickup apparatus with a horizontal line interpolation function having a plurality of solid state image pickup elements, three chrominance signals obtained from the plurality of solid state image pickup elements are shifted in vertical phase from one another, whereby when a horizontal interpolation line is synthesized, in the case where the interpolated video signal is viewed as a whole of three chrominance signals (e.g. when a luminance signal synthesized from G, R, and B signals by matrix operation is considered), deterioration in vertical frequency response characteristic can be reduced, and besides deterioration in vertical sharpness of an image can be reduced. Further, by combining a frame signal in a pseudo fashion, a high-quality frame still image can be formed.
