ABSTRACT:
To record a CRT image on a photosensitive recording medium, the latter is exposed to an image bearing light emanated from a display screen of a CRT. Currents flowed through horizontal and vertical deflection coils are varied to thereby change the horizontal and vertical sizes of the image displayed on the CRT, whereby the size of the image recorded on the recording medium can be changed without moving the position of the recording medium and/or a focusing lens interposed between the display screen of the CRT and the recording medium.
