Abstract
To prevent color turbidity due to residual image characteristics of an image sensor and to improve low color saturation due to rise-response characteristics of the image sensor, a object image to be taken is separated into three primary color images two fields by two fields for each primary color image through a color separating rotary filter; and transduced into six-field primary color image signals. Each primary color image signal obtained at each first field (this includes a preceding different-color residual image signal) is omitted, but each primary color image signal obtained at each second field (this includes a preceding same-color residual image signal) is outputted as video signals in sequence.
