<p>PURPOSE:To enable an appropriate recording even when a deflection frequency of an input video signal is widely ranged by adopting a fixed value suitable for an internal monitor for a horizontal deflection period and adopting an optional value suitable for photosensing to a photosending body for a vertical deflection period in the case of picture display onto an internal monitor. CONSTITUTION:Picture data in a digital picture memory 20 are read under the control of a memory read control circuit 31. An output of an oscillator 32 is inputted to a read address generator 34 via a read reference clock generator 33 and an output of an address generator 34 is inputted to the digital picture memory 20 as a read address. Recording data read from the memory 20 are fed to an internal monitor 40 via a D/A converter 35. A horizontal deflection signal Hsi and a vertical position signal Vpi are fed to the internal monitor 40 from the address generator 34. The picture data displayed on the internal monitor 40 are projected and recorded onto a photosensing body 60 through an optical system 50 such as a lens.</p> |
