Description

The camera wireless sync system which is Radio ID Recognition Function

The present invention has been proposed to create a wireless synchronization system for a camera without crosstalk. The wireless transmitter encodes the camera's performance information with a registration ID code, and then transmits a signal at a radio frequency, and the wireless receiver accepts and decodes the signal. After that, the objective is to implement an accurate and no crosstalk wireless tuning system that executes only the matching signal after comparing with the registered ID code.

The apparatus of the present invention for achieving the above object is, a wireless transmitter for transmitting a radio frequency signal including a registration ID code in the camera execution information connected to the camera; and a wireless receiver for receiving the transmitted signal; An ID code verification unit including a microprocessor for controlling only execution information matching with an input registration ID code after decoding the signal received from the radio transmitter; It includes a wireless synchronization system for a camera having a wireless ID recognition function consisting of an interface unit for connecting various camera execution information to an external device.

As a technique similar to this wireless tuning system, an example can be found in the digital door lock device. When the digital door lock is searched after the registration ID transmitted periodically from the wireless transmitter of the remote control key is received while the wireless receiver is in the standby state, it is searched from the input registration ID stored and registered in the door lock in advance. Unlock the lock.

The frequency tuning method of the conventional wireless wireless tuner for a camera can transmit and receive simple information only through a channel by a dip switch, and a lot of malfunctions have occurred due to crosstalk with other wireless devices. Only wireless shutter release and lighting synchronization are provided. Even in the case of channels, only 10 channels or less of signal tuning is possible using a dip switch, and when there are more than 10 tuners in a narrow space, channels are overlapped and crosstalk occurs. Other camera wireless tuning method is an infrared tuning method, which has a limitation of transmission and reception distance and direction, and often cannot be operated according to environmental conditions.

The present invention has been proposed to solve the above problems, and the wireless transmission unit is wireless when the user receives an operation command such as half shutter, full shutter information, photo data, camera execution information (related to a personal flash or lighting), or the like. Insert the registration ID code unique to the transmitter into the execution information to generate a signal, and the wireless receiver analyzes the signal received from the wireless transmitter to select only the signal with the input registration ID code inserted and then the photo data, shutter information, and camera execution information. It is an object of the present invention to provide a wireless tuning system without crosstalk by performing a command.

By inserting registration ID codes that do not overlap each product into the transmitter, it provides a reliable data transmission / reception function without crosstalk during wireless synchronization, and it is equipped with a universal terminal so that it can be used widely regardless of camera type. do.

The present invention as described above relates to a wireless tuning system having a wireless ID recognition function and its control method has the following advantages.

First, there is no crosstalk during wireless tuning.

Since only the camera execution information inserted with the wireless ID code of the wireless ID recognition method executes the command, there is no crosstalk during wireless synchronization even in a space having a lot of radio frequency information in a narrow space.

Second, ID code can be re-registered.

ID code input registration function in the wireless receiver, if the wireless transmitter lost, you can re-register the ID code in the wireless receiver.

Third, it may provide convenience to the user of the wireless tuning system.

Since a plurality of wireless ID codes can be registered, it is possible to freely configure the equipment to be wirelessly tuned according to a user's intention when wirelessly tuning a plurality of devices at a time.

Fourth, the utilization is large.

Equipped with a universal connector terminal, the user does not need to purchase a duplicate product in accordance with the camera model changes.

Fifth, it is possible to increase the utilization of various wireless camera accessories.

Various information of the camera can be transmitted and received by wireless data, and various accessories related to the camera can be used wirelessly.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
