Patent JP-H11261842-A (JP)
Title: Video signal processor
Inventor: SUZUKI TAKASHI
IPC: H04N5/073
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To realize a frame synchronizer of a least hardware constitution by keeping a fixed relation between the memory writing clock frequency and the memory reading clock frequency. SOLUTION: The video signals which are inputted via an input terminal 101 are written in a memory 100 corresponding to the output of a write control part 102 and then read from the memory 100 corresponding to the output of a read control part 104 and outputted to an output terminal 105. In such a case, the frequency and the phase information of a write control signal (synchronized with the input video signal) are corrected by a correction circuit 103 to control the frequency and phase of the read control signal of the part 104. As a result, the signals can be read from the memory 100 at a rate lower than the writing rate (or at higher rate based on the correction contents). In this case, the synchronous relation is secured between the input and output to simplify the memory control.
