Patent ID: 7480450

Claim:
A camera system where a camera for image capturing with built-in exposure control mechanism and a camera for providing strobe light with built-in strobe mechanism are synchronously connected via a radio network, wherein said camera for image capturing comprises: determining means for determining a point at which to start exposure for image capturing Tx and a point at which to start strobe emission Tf; emission start command output means for outputting a strobe emission start command to start strobe emission at said point at which to start strobe emission Tf; exposure start command output means for outputting an exposure start command to start exposure at said point at which to start exposure for image capturing Tx; and exposure control means for controlling said exposure control mechanism so as to start exposure at said point at which to start exposure for image capturing Tx in response to said exposure start command, said camera for providing strobe light comprises: emission control means for controlling said strobe mechanism so as to start strobe emission at said point at which to start strobe emission Tf in response to said strobe emission start command that has been received via said radio network, and said determining means determines the point at which to start exposure for image capturing Tx and the point at which to start strobe emission Tf such that said point at which to start exposure for image capturing Tx is earlier than said point at which to start strobe emission Tf, a time difference between said point at which to start exposure for image capturing Tx and said point at which to start strobe emission Tf becomes larger than the synchronization error between said camera for image capturing and said camera for providing strobe light, and strobe emission ends before completing exposure.
