Abstract

[Challenge] To provide a gimbal-integrated camera that enhances user convenience, is low-cost, and has low power consumption. [Solution] When a trigger is issued to indicate the end of shooting, the drive device is controlled to move the imaging unit to a first position. After that, the imaging unit is maintained in the first position, and when it is determined that it is no longer in use, a power-off trigger is issued to turn off the power to the drive device.

Description

This invention relates to an imaging device. Conventionally, in gimbal-integrated cameras where the camera unit is driven to rotate, the camera unit is supported by multiple support parts connecting multiple drive devices. When the power to such a gimbal-integrated camera is turned off, the drive devices are not energized, resulting in the multiple support parts and camera unit connected to the grip being unstable and not fixed. Furthermore, if the camera unit and support parts protrude from the grip, it is unsuitable for portability. Therefore, Patent Document 1 discloses a technique in which, when a power-off command is received, the gimbal is driven to the folded position, that position is maintained for a certain period of time, and then the power is turned off.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. (Example 1) Figure 1 is a perspective view showing the configuration of a gimbal-integrated camera, which is an example of an imaging device according to Embodiment 1 of the present invention. The configuration of the gimbal-integrated camera of Embodiment 1 will be described below with reference to Figure 1. The gimbal-integrated camera 1 consists of a main unit 2 and an anti-vibration mechanism 3. The main unit 2 is comprised of a housing 21, which also serves as a grip for the user to hold during shooting. It is equipped with a first operation unit 22a, a second operation unit 22b, and a display unit 23. The housing 21 further includes multiple input units (not shown), an external media slot, a tripod mount, a strap, external input/output terminals, a power terminal, a tally lamp, a microphone, and a speaker. The vibration isolation mechanism 3 consists of a first drive unit 31, a first support member 32, a second drive unit 33, a second support member 34, and a third drive unit 35. The first support member 32 is rotatably connected to the housing 21 of the main body 2 via the first drive unit 31, and the second support member 34 is rotatably connected to the first support member 32 via the second drive unit 33. Furthermore, the camera unit 36 is rotatably connected to the second support member 34 via the third drive unit 35. In this embodiment, the rotation axis of the first drive unit 31 is defined as YAW, the rotation axis of the second drive unit 33 as ROLL, and the rotation axis of the third drive unit 35 as PITCH. Furthermore, the angle of each rotation axis when the vibration isolation mechanism 3 is in the state shown in Figure 1 is defined as 0°, and the amount of rotation and the direction of rotation are expressed using the plus and minus signs shown in Figure 1. The first support member 32 is fixed to the first drive unit 31 and the second drive unit 33, respectively, with screws (not shown). The second support member 34 is fixed to the second drive unit 33 and the third drive unit 35, respectively, with screws (not shown). Note that each drive unit may be fixed by adhesive. Furthermore, cable paths (not shown) are formed between each movable part and support member, and power cables are assumed to pass through them.
