9 therefore the output control circuit 8 as mentioned above is not always necessary for this embodiment further it is also possible to make the sequence control unit 9 have an additional function as scanning control means in this case scanning can be controlled by the sequence control unit 9 in such manner that the stored charges are read out for an optional number of frames selected among a plural number of continuous frames of the same color the construction of the rotary filter 1a is shown in detail in fig4 referring to fig4 the rotary filter 1a is rotated in the direction of arrow a the filter 1a is divided into three color sections r section g section and b section each color section comprises three frames more specifically the r section comprises three r frames g the section comprises three g frames and b section comprises three b the frames therefore in this embodiment the residence time of one color section is a time corresponding to three frames under the control by the control unit 9 the filter 1a is rotated at uniform speed and the period of rotation of the filter is set to a multiple of an integer of one frame time x 9 every last frame designated by 1d is used a video signal readout frame scanning is carried out sequentially frame by frame and the stored charges on the image pickup surface 3 are read out frame by frame in response to the readout of at least the last one frame the output controller 8 outputs a video signal on lead 4 as seen in fig5.
