Abstract
PURPOSE:To prevent not only the distortion of picture but the deterioration of resolution, by securing a synchronization between the information of the adjacent picture elements on the same line and the information of the picture elements of two lines adjacent to the previous picture elements. CONSTITUTION:The spot sequential signals of red R, green G and blue B supplied from the pickup element CCD10 are supplied to an A/D converter 30 via the AGC circuit. The output color signal of the converter 30 receives the processes such as a white clipping, a gamma compensation or the like and is then separated into the G (R, B) signals via the switch SW. Then the R and B signals are supplied to the nonseparable 2-dimensional digital filter 50 to receive the prescribed transmission property. Thus the prescribed frequency region is limited, and at the same time the output is supplied to the Y/G forming circuit 60 to form the luminance signal components YR and YB plus the color signals CR and CB. The signal components CR and CB are modulated by a digital encoder 70 to form a carrier chrominance signal, and the components YR and YB are synthesized through a synthesizer 80 to be converted into an analog signal by a D/A converter 90. A similar process is carried out to the digital signal G.
