When trying to control the camera with the camera, the following problem occurs. That is, when a camera control command is assigned to the operation of the arm and the wrist to which the remote control device 24 is attached, there is a possibility that the command is executed by a casual operation that the photographer does not intend. On the other hand, if a command is associated with a complicated operation that is not included in a normal operation in order to prevent such a malfunction, it becomes difficult for the photographer to operate the operation.

This focuses on the fact that people rarely work with their arms raised to shoulder level and usually move their hands under their shoulders. When raising the arm to near the shoulder position, there are many intentional movements, and it is rare to raise hands unconsciously. Therefore, by detecting not only the movement of the hand ahead of the wrist but also the movement of the arm and assigning a command to an operation combining the movements, the command issuance (malfunction) due to an unconscious operation unintended by the photographer. Can be prevented.

Is executed so that the command is executed under the condition However, as for the shooting start signal, if such a two-stage input is performed, a photo opportunity is missed, so that the confirmation display and the input of the execution instruction are omitted.

May be used. In this case, the remote controller has a two-block configuration as shown in FIG. That is, two remote control devices 64, a first remote control device 64 for detecting a muscle current associated with the movement of the hand ahead of the wrist and a second remote control device 65 for detecting a muscle current associated with the movement of the upper arm. , 65 controls the electronic camera body 10.
