ABSTRACT:
An apparatus for processing a still picture in a video laser disc player, comprising a memory store interval control section for outputting a memory store interval control signal in response to field and field reference signals from a field separation section, an external still picture signal and an even field designating signal, a memory control section responsive to the memory store interval control signal for outputting an address increment signal and a self-horizontal synchronization signal and outputting a chip enable signal, a write/read select signal and a write enable signal to a video memory, a memory address generation section for outputting a write or read address signal to the video memory, the even field designating signal to the memory store interval control section and a color burst phase correcting signal in the still picture mode in response to the address increment signal and the self-horizontal synchronization signal, and a video signal processing section responsive to the color burst phase correcting signal and an external video switching signal for, in the still picture mode, outputting an input video signal from a laser disc as a memory output video signal to the video memory and processing an input video signal of one field from the video memory as a video signal of one frame.
