Camera system, signal delay amount adjusting method and program

摘要

A system and method for adjusting one or more signal delays. The signal delays are adjusted by obtaining delay amounts of video signals associated with respective camera units and respective camera control units, the camera units being coupled to respective ones of the camera control units via an asynchronous network, and adjusting one or more of the delay amounts.

1. A method for adjusting one or more signal delays, comprising:
obtaining delay amounts of video signals associated with respective camera units and respective camera control units, the camera units being coupled to respective ones of the camera control units via an asynchronous network; adjusting one or more of the delay amounts, wherein one of the delay amounts is selected as a reference delay amount and the other delay amounts are adjusted according to the reference delay amount, and wherein the other delay amounts are adjusted to be the same as the reference delay amount, or to be the same as the reference delay amount plus n frame periods, n being a positive integer that is greater than or equal to one; and for each other delay amount,
determining whether or not the delay amount is greater than the reference delay amount;when the delay amount is less than the reference delay amount, adjusting the delay amount to be the same as the reference delay amount; andwhen the delay amount is greater than the reference delay amount adjusting the delay amount to be the same as the reference delay amount plus n frame periods, n being a positive integer that is greater than or equal to one.
