Claims (1)

[Scope of utility model registration request] The phase of the fundamental wave component of the image pickup tube output signal is determined by repeating a specific array pattern of multiple types of color strips, each having a predetermined strip width, and the phase of the fundamental wave component of the image pickup tube output signal is determined in accordance with the repetition of the array pattern. A color separation striped filter, in which the colors of the plurality of color strips are set so as to vary depending on the color, is provided in the optical path to the photoelectric conversion section of the image pickup tube, and The optical image is given to the photoelectric conversion section of the image pickup tube through a color separation striped filter, and the image pickup tube obtained by capturing an image of any specific color with the image pickup tube prior to image pickup. An information signal corresponding to at least one frame period of the output signal is stored in a storage device, a reference signal for color signal demodulation is obtained based on the information signal stored in the storage device, and the image pickup tube is thereby In a color imaging device which is configured to demodulate a predetermined color signal from the output signal of a device by synchronous detection or the like, an arbitrary specific color is imaged by an imaging tube provided in the color imaging device prior to imaging. a signal processing means for receiving the obtained image pickup tube output signal and improving the signal-to-noise ratio of the signal; and a signal processing means corresponding to at least one frame period of the signal processed by the signal processing means. The external add-on device includes a removable storage device capable of storing information signals, and the removable storage device in the external add-on device is provided with a color storage device prior to imaging. An information signal corresponding to at least one frame period in a camera tube output signal obtained by capturing an arbitrary specific color using a camera tube installed in the camera is stored in a removable storage device in an external additional device. After that, the color imaging device is used by removing the external addition device and installing a removable storage device in the external addition device into the color imaging device.
