PURPOSE: To make a control easy and to enable a miniaturization without requiring an independent and separate light source by rotating a color filter between an image pickup lens and a solid-state image pickup element and performing the rotation by using the driving power of a recording system.
CONSTITUTION: The light transmission part of a rotation plate 202 is located at the optical path between a lens 201 and a solid-state image pickup element 205, and R, G, B light transmission parts are provided around the center axis at equal spaces. While the rotation plate 202 rotates once, each video signal of R, G and B is obtained and each signal is successively recorded in a rotation cylinder part 209. The output of the sensor to be provided on a motor 208 judges the relative location of the rotation cylinder 209 and the optical location of the rotation 202. The optical exchange/storage operation of the solid-state image pickup element 205 is synchronized with the rotation of the color filter. Therefore, the driving pulse from a driving circuit 301 is imparted so that the storage/reading of electric charge may be performed every time the R, G and B of the color filters are incoming.
