Vertical line-speed conversion method and its circuit for home HDTV camera

摘要

The present invention relates to a home HDTV camera adapted to a HDTV standard using a general-purpose 4-CCD. The G1 channel data outputted from a G1CCD of a 4-CCD is written at a speed twice as fast as the writing speed A first memory for reading the written data, a second memory for writing the G2 channel data output from the G2CCD among the 4-CCDs for a 1H period and then writing the data at a speed twice the writing speed, And a multiplexer for alternately selecting data read from the memory and data read from the second memory to output a wideband G signal. In order to satisfy the HDTV standard by using a general-purpose CCD, the number of effective data sections is simplified The cost can be saved by placing the body.
