Document Type and Number:
Japanese Patent JP2869006
Kind Code:
B2
Abstract:
Interlaced image signals are converted into non-interlaced image signals and the scanning lines are also thinned out (i.e., the number of lines is reduced). Line memories L1-L5 are provided in a number (5) Corresponding to the number of horizontal scanning lines thinned out by a predetermined number of lines every number of lines determined from the total number of horizontal scanning lines of the PAL signal and that of the NTSC signal. A demultiplexer 12 selects the memories L1-L5 so that each PAL signal corresponding each of first to fifth ones of six horizontal scanning lines is stored. A selector 14 sequentially read the memories L1-L5 twice during an interval from the time when the PAL signal corresponding to the first horizontal scanning line is stored to the time from storing the PAL signal corresponding to the first horizontal scanning line but before storing the PAL signal corresponding to the seventh horizontal scanning line.
