MASTER FLASH APPARATUS AND METHOD

摘要

A master flash apparatus which emits light when an image capturing device outputs a synchronous light emission command after the image capturing device outputs a first light emission start command. The apparatus can perform wireless communication with a slave flash apparatus which emits light in response to a second light emission start command received from the master flash apparatus. A transmission unit transmits the second light emission start command to the slave flash apparatus when a predetermined time has elapsed after the image capturing device outputs the first light emission start command. A measurement unit measures a time from the output of the first light emission start command from the image capturing device to the output of the synchronous light emission command from the image capturing device. An adjustment unit adjusts the predetermined time based on the time measured by the measurement unit.

1. A master flash apparatus which is connected to an image capturing device, and emits light when said image capturing device outputs a synchronous light emission command synchronized with traveling of a shutter after said image capturing device outputs a first light emission start command, wherein
said master flash apparatus can perform wireless communication with a slave flash apparatus which emits light in response to a second light emission start command received from said master flash apparatus, and said master flash apparatus comprising: a transmission unit configured to transmit the second light emission start command to said slave flash apparatus when a predetermined time has elapsed after said image capturing device outputs the first light emission start command; a measurement unit configured to measure a time from the output of the first light emission start command from said image capturing device to the output of the synchronous light emission command from said image capturing device; and an adjustment unit configured to adjust the predetermined time based on the time measured by said measurement unit.
