IMAGE PROCESSING SYSTEM, IMAGE PROCESSING DEVICE, AND CONTROL METHOD FOR THEM

摘要

PROBLEM TO BE SOLVED: To more securely synchronize controls of a plurality of video systems without increasing the number of signal lines for homogeneous signals.SOLUTION: In an image processing system in which a first image processing device and a second image processing device display images in synchronization with a homogeneous lock signal output from the first image processing device, the first image processing device deforms a synchronization signal pulse included in the homogeneous lock signal, and modifies a display process in synchronization with a frame or field specified by the timing of the deformation of the first image signal to be displayed. Additionally, the second image processing device detects the deformation of the synchronization signal pulse included in the homogeneous lock signal, and modifies a display process in synchronization with a frame or field specified by the timing of the detection of the deformation of a second image signal to be displayed.
