PURPOSE:To prevent the deterioration of a picture quality due to the generation of a pseudo signal by using the correlation between two adjusent rows and obtaining a luminance signal and chrominance signal. CONSTITUTION:The charge pattern accumulated at an image pickup element 2 is synchronized to a synchronizing signal by an image pickup element driving circuit 15, read successively by scanning, digitized by an A/D converter 3 and thereafter, the pattern is written into a buffer memory 6. After the writing of all screens is completed, two adjusent rows are read from output terminals 6-1 and 6-2 in respective fields. After the signal of two rows is added by an adder 9, processed by a luminance signal processing circuit 10 and goes to a luminance signal Y. On the other hand, the signal of these two rows is respectively processed by chrominance signal processing circuits 11 and 12 and goes to respectively a B-G signal and an R-G signal. These signals are converted to a signal suitable to recording by a recording signal processing circuit 25 and recorded to a recording medium 26 which can be attached and detached freely with a camera main body 22.
