PICTURE SIGNAL PROCESSING DEVICE AND PICTURE SIGNAL PROCESSING METHOD

摘要

A picture signal processing device includes an A/D conversion unit configured to convert an input analog picture signal into a digital picture signal; an automatic image correction unit configured to correct the digital picture signal from the A/D conversion unit; a narrowing-down unit configured to narrow down possible formats of the analog picture signal based on horizontal and vertical signal frequencies of the analog picture signal, horizontal and vertical synchronizing signal polarities and vertical line count; and an identification unit configured to identify the format of the input analog picture signal from among a plurality of narrowed-down candidate signal formats.
