Apparatus for processing still picture in video laser disc player

An apparatus for processing a still picture in a video laser disc player, comprising:

• a video memory for storing or outputting a video signal of one frame played back from a laser disc in the unit of field every frame in a still picture mode in response to a write or read address signal and control signals;
• field separation means for separating odd and even fields from an external composite synchronization signal and outputting a field signal designating the odd and even fields and a field reference signal designating start points of the odd and even fields in accordance with the separated odd and even fields;
• memory store interval control means for outputting a memory store interval control signal in response to the field signal and the field reference signal from said field separation means, an external still picture signal and a signal designating the even field so that an even field portion of a video signal of one frame to be processed as the still picture in the still picture mode can be stored in said video memory;
• memory control means responsive to the memory store interval control signal from said memory store interval control means 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 as the control signals to said video memory;
• memory address generation means for outputting the write or read address signal to said video memory, the even field designating signal to said memory store interval control means 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 from said memory control means;
• and
• video signal processing means responsive to the color burst phase correcting signal from said memory address generation means and an external video switching signal for outputting an input video signal of one frame played back from the laser disc directly as an output video signal in a normal mode and, in the still picture mode, outputting the input video signal from the laser disc as a memory output video signal to said video memory, processing an input video signal of one field from said video memory as a video signal of one frame and then outputting the processed video signal as the output video signal.
