Patent attributes
An image processing device includes a synchronizing signal separation section, a counting section, a synchronizing signal determination section, and a video format determination processing section. The synchronizing signal separation section separates a horizontal synchronizing signal from a received broadcasting signal. The counting section counts the pulse number of the separated horizontal synchronizing signal. The synchronizing signal determination section determines presence/absence of a synchronizing signal based on the counted value by the counting section. The video format determination processing section determines a video format of the received broadcasting signal based on the number of scan lines. The video format determination processing section determines the video format only when it is determined that there is a synchronizing signal by the synchronizing signal determination section.
