Title:
CAMERA VIDEO TRANSFER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/014728
Kind Code:
A1
Abstract:
[Problem] If the length of cables between CHUs and CCUs differs, the imaging timing deviates for a plurality of CHUs. [Solution] In order to match the imaging timing for CHUs, each CCU phase control circuit transmits, to the CHUs, a frame pulse for which the phase has been advanced by exactly a correction time corresponding to each cable, with respect to a time position of the frame head of a reference synchronization signal input to the CCU. Due to this configuration, the timing of the frame head of a synchronization signal output from a synchronization signal generation circuit and received by the CHUs matches for a 1m transfer, a 400m transfer and a 1km transfer. Consequently, the CHU imaging timings can be matched.
