Method and apparatus of repeatedly recording optical image information and image pickup device.

摘要

An image pickup device comprising a device for recording an optical information on a recording member capable of erasing and rewriting said optical information thereon, a device for erasing a prerecorded optical information on the recording member prior to recording a subsequent optical information to be recorded on the recording member. The recording device records the optical information as a charge image on the recording member (10) by applying an electrical potential to a writing head of the recording means and the recording medium. A method of repeatedly recording optical pattern as an electrostatic charge image on a reversible recording member (10) capable of erasing and rewriting said electrostatic charge image thereon comprising the steps of recording a first frame of electrostatic charge image by transforming an optical pattern formed on said reversible recording member by optical device into said first frame of electrostatic charge image, erasing the first frame of electrostatic charge image recorded on said reversible recording member by erasing device, recording a second frame of electrostatic charge image by transforming said optical pattern formed on said said reversible recording member into said second frame of electrostatic charge image. An image pickup device comprising a device for recording an optical pattern as an electrostatic charge image on a reversible recording member capable of erasing and rewriting said electrostatic charge image thereon device for transforming an optical pattern formed on said reversible recording member by optical device into said electrostatic charge image, erasing device (EA) for erasing a prerecorded electrostatic charge image on said recording member prior to recording a subsequent electrostatic charge image on said reversible recording member.
