Abstract

PURPOSE: To accurately recognize whether or not remote control standby time has elapsed by moving a lens barrel to a position for displaying the automatic release of the setting of remote control photographing when the remote control standby time has elapsed. CONSTITUTION: When a camera user turns on the remote control mode setting switch 21 of a remote control photographing mode setting means 2, remote control photographing mode setting information is inputted from a remote control mode detection circuit 22 to a CPU 1. The CPU 1 moves a lens barrel to an actuation impossible position by using a lens barrel driving means 5 in the case where the counting of a timer circuit 4 measuring the elapsed time from the point of time when the remote control photographing mode is set is started and the remote control operation is not executed even when a specified time has elapsed. Thus, the camera user visually confirms the state of the lens barrel from a distant place, thereby accurately recognizing whether or not the remote control standby time has elapsed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera that can be remotely controlled by a remote control device (hereinafter abbreviated as a remote control device), and in particular, has a function of allowing a photographer to accurately recognize the state of the camera. Regarding possible cameras.

[0002]

2. Description of the Related Art As is well known, a remote control device for a camera includes an operating device which is constructed separately from the camera body.
And a receiving unit built in the camera body, for transmitting an operation signal (mainly a shutter release signal) for operating the mechanism in the camera body to the receiving unit to the operating device. The transmission means of is built in.

In a conventional camera having such a remote control device, even if a predetermined time elapses after the remote control shooting mode is set by the remote control shooting mode setting means provided in the camera body, the operation is performed. If the operation signal is not sent from the device to the receiving means, the function of automatically canceling the setting of the remote control shooting mode is provided in order to suppress the consumption of the battery in the camera body.

On the other hand, with the recent miniaturization of cameras, the batteries incorporated therein are becoming smaller, and as a result, the predetermined time (that is, the standby time for remote control) is short in newly released cameras. Tends to become.

[0005]

The conventional camera having the above remote control device has the following drawbacks.

(1) Since the remote control waiting time from when the remote control shooting mode is set to when the remote control shooting mode is automatically released is constant, in a certain shooting situation, the photographer performs the operation within the remote control waiting time. Even if the operator can operate the operation device, the operator cannot operate the operation device within the remote control waiting time because the photographer took time to move to a predetermined place in other shooting situations, and the operator does not operate the operation device. It happened that the mode setting was automatically canceled before operating the vessel.

(2) Since the conventional camera is not provided with means for allowing the photographer to clearly recognize the fact that the mode is automatically released, the photographer does not automatically release the mode. I mistakenly recognized that it was not automatically released, and performed a shooting operation, then after taking out the film from the camera and developing it, I found that it was not shot, and I mistakenly thought that the camera or remote control device was malfunctioning. There was something that happened.
