Japanese Patent JP6719994
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow deviation among synchronous signals generated by a plurality of apparatuses to be adjusted while preventing a circuit scale from getting larger.SOLUTION: When a vertical synchronous signal of a second camera is adjusted based on a vertical synchronous signal of a first camera, the first camera transmits a value W1 of a reception waiting period measuring counter, a value W2 of a transmission waiting period measuring counter, and a value RC of a reset number counter to the second camera. Then, the second camera synchronizes time by calculating an amount of synchronization adjustment and timing of synchronization adjustment from the received those values and a synchronization adjustment waiting period tRTT.SELECTED DRAWING: Figure 8
