Information transmitting apparatus using flash light emission

Abstract

In an information transmitting apparatus capable of transmitting information by using flash light emission of a flash light emission tube, communication data is detected at timing synchronized with a predetermined period and, when the detected communication data indicates a light emission instruction, a predetermined light emission signal is formed and outputted to cause the flash light emission tube to make light emission, wherein a time interval from a point of time at which the light emission instruction has been detected to a point of time at which the light emission signal is outputted is varied according to a time interval from a point of time at which the preceding light emission has been performed to a point of time at which the light emission instruction for the current light emission is detected, so that the intervals of flash light emission are adjusted.
