PURPOSE:To eliminate a false signal due to reflected component without causing the deterioration of resolution in the horizontal direction, by installing vertically an optical low-pass filter. CONSTITUTION:An optical low-pass filter is vertically arranged in front of a CCD3. An output read out of the CCD3 is written in a frame memory 7, and an output read out of the memory 7 is fetched in registers 8-10. The outputs of the registers 8-10 are processed by an adder 11 and a multiplier 12 and supplied to a demultiplexer 13. The output of the demultiplexer 13 is processed by adders 14, 16, 17, 19, 20 and 27, delay circuits 15, 18, 21 and 28, low-pass filters 22 and 23, a matrix circuit 24 and a sequential circuit, and a color signal is synthesized as a difference signal between picture elements existing in the same train. |
