Operation
An operation of the remote cradle control system 1 will be described below with reference to
In order to attach the camcorder 3 to the cradle 2, first, as illustrated in
Then, the connection cable 5 illustrated in
Subsequently, when the plate 42 attached to the camcorder 3 is attached to the cradle body 41, for example, as illustrated in
With this state, as illustrated in
Similarly, the pan initialization unit 75 of the cradle 2 causes the pan motor 51 to rotate in counter-clockwise direction until the end-point switch 66 is operated. Then, the pan initialization unit 75 of the cradle 2 obtains a rotational position of the output shaft of the pan motor 51 when the end-point switch 66 is operated based on the detected result input from the encoder 78 when the end-point switch 66 is operated. The pan initialization unit 75 of the cradle 2 causes the RAM 71 to store the obtained rotational position therein. Then, the pan initialization unit 75 of the cradle 2 calculates a neutral position of the output shaft of the pan motor 51 based on the obtained two rotational positions and causes the RAM 71 to store the calculated result therein. When the initialization of the pan motor is completed (S330), the pan initialization unit 75 outputs an initialization completion notification to the camcorder 3 (S340). When the initialization completion notification is input from the cradle 2 (S340), the camcorder 3 transfers the initialization completion notification to the smart phone 4 (S350).
Then, a mode selection screen is displayed on the folding LCD 7 of the camcorder 3 to prompt a mode selection (S360).
In the present embodiment, the camcorder 3 includes a playback mode and a cradle control mode. The playback mode is a mode in which the signal selection unit 27 illustrated in

In addition, if the user wants to initialize the pan operation of the cradle 2, it may be achieved by pressing the initialization button 10 illustrated in
Here, it is assumed that the user wants to adjust the imaging direction F of the camcorder 3. In this case, the user operates the pan button of the cradle remote control button group S3 of the smart phone 4 illustrated in
The remote operation unit 96 of the smart phone 4 displays the present rotational position of the output shaft of the cradle 2 on the remote operation screen S based on the input rotational position notification information.
Above, the operation of the remote cradle control system 1 has been described. The operation of the remote cradle control system 1 may be changed as follows, for example.
The user displays the mode selection screen for prompting the mode selection on the LCD 90 of the smart phone 4, instead of selecting the cradle control mode by operating the touch panel provided in the folding LCD 7 of the camcorder 3 (S370), and the user may operate the touch panel 91 so that the cradle control mode is selected.
In addition, in the above-described embodiment it is assumed that the camcorder 3 takes the moving image, but the camcorder 3 may take a still image instead of the moving image. Even when the camcorder 3 takes the still image instead of the moving image, the configuration for controlling the pan operation of the cradle 2 using the camcorder 3 or the smart phone 4 significantly functions.
