PURPOSE:To eliminate an external switch circuit in which an output signal is replaced even if an interlacing operation is executed in an image pickup element for reading out a signal charge of two lines by two horizontal CCDs. CONSTITUTION:A signal charge stored in a photoelectric converter 2 is transferred by vertical CCDs 11-1N to horizontal CCDs 3, 3', and simultaneously read out in two lines by CCDs 3, 3'. A gate connected with a terminal M2 and a storage unit connected with a terminal M2 are provided between the vertical CCDs and the horizontal CCD3'. Two lines of signal charges are transferred to the CCDs 3, 3' without using the storage unit at first field reading time. The order of the lines to be transferred to the CCDs 3, 3' are replaced to be transferred by utilizing the storage unit at second field reading time. Then, even if the combination of the lines to be read simultaneously is altered at every field to be interlaced in a single plate color image pickup element using a mosaiclike color filter, the horizontal CCDs 3, 3' always output the same color signals, thereby eliminating an external switch circuit. |
