Abstract

PURPOSE:To achieve high horizontal and vertical resolution rate over th entire picture, by discriminating the degree of vertical correlation of picture of objective per a small region and changing the rate of interpolation between video elements according to the result. CONSTITUTION:A luminance signal Y filter is located at each other elements for horizontal and vertical direction, and a red signal R filter and a blue signal B filter are repetitively located between the elements. An output signal from a color solid-state pickup element providing color filters with such arrangement is applied to 1H delay lines 2 and 3 sequentially. Thus, on output lines 4-6, a real time signal, 1H delay signal and 2H delay signal are obtained. The Y signal component only is picked up at gate circuits 9-11, and the vertical correlation per each video element of a video luminance signal is discriminated at a correlation device 13. At a variable mixer 14, the 1H delay signal is interpolated between real time signals of missing Y signal, and when the vertical correlation rate discriminated with the output of the correlation device 13 is higher, the rate of interpolation is increased and a luminance signal 15 is obtained.
