This invention relates to the mounting of cameras, including still cameras and particularly video cameras. Illustrative embodiments of the invention relate to mounts for video cameras for use during outdoor activities and action sports e.g. cycling, mountain biking, hiking, climbing, skiing and snowboarding, surfing, sky diving, sub-aqua diving, etc.
It is known to mount still and video cameras so that they can record images or video during action sports, for example wearable video cameras can be mounted to a helmet, bicycle, surf board, etc. to capture action footage. So-called “action cams” can typically be mounted in different orientations, e.g. on a helmet, but the orientation of the camera is generally fixed once it has been mounted in a particular position. This can be problematic when activities do not take place on the level and the camera may be tilted or inverted during use. A horizon adjustment may be required to adjust the orientation of the horizontal image plane in relation to the mounting orientation of the camera body, e.g. during post-processing of video data recorded by the camera. Furthermore a user may wish to be able to adjust an orientation of a camera after it has been mounted.
WO 2009/018391 A1 discloses a manual horizon adjustment control in the form of a rotary ring around the lens. Manual rotation of the ring during use of the camera either rotates the CMOS image sensor, so that post-processing is not required, or encodes the video data with the correct horizon so that post-processing adjustment is automatic. However this requires an additional manual adjusting step every time the mounting orientation is changed. WO 2012/037139 A2 shows examples of a camera mounted in different orientations with the lens manually rotated to provide for horizon adjustment.
According to a first aspect of the present invention there is provided an adjustable mount for a camera, the mount comprising a base for mounting to an object in a fixed position and a body that is removably connected to the base, the base defining a horizontal plane for the mount, and wherein, when the body is connected to the base in use, the body is rotatable about a vertical axis passing through the base and a mounting portion of the body is pivotable away from the horizontal plane so as to enable adjustment of an orientation of a camera supported on the mounting portion.
It will be understood that such a mount is a two-part mount comprising the mount base and the mount body removably connected thereto. This means that a single mount base can be fixed in position on an object such as a helmet, while different mount bodies may be connected to the base at different times. The mount base may, for example, be permanently attached to an object such as a helmet by adhesive. The removable mount body enables different cameras to be quickly interchanged on the same fixed mount base. Furthermore, the double adjustability of the mount body means that, once installed, a user can easily adjust the shooting direction and angle of a camera on the mount. The body being rotatable about a vertical axis passing through the base, e.g. in a horizontal plane parallel to the base, allows the camera to swivel from side to side. A portion of the body being pivotable away from the horizontal plane, e.g. pitching out of a horizontal plane parallel to the base, allows the camera to tilt up and down. In practice this means that a camera on the mount can be adjusted in two ways to have a wide variety of different orientations. This is ideal for an action camera, especially a video camera.
The body may be removably connected to the base in any suitable way. In various embodiments the removable connection may comprise a frictional engagement, preferably one that can be selectively released by a user applying a force to overcome the frictional engagement. For example, a hook and loop fastening, such as Velcro®, may be used. However a potential problem with a frictional engagement is that the body may be loosened from the base during use of the mount, especially if the mount is not generally stationary but subject to forces during wear. The mount may, for example, be worn by a person during outdoor activities and action sports. It is therefore desirable for the removable connection to comprise a positive connection arrangement, e.g. one that must be positively disconnected to enable release of the body from the base. This can avoid accidental decoupling of the body from the base during use.
In a preferred set of embodiments the body is removably connected to the base by an interlocking arrangement, for example a positive interlocking arrangement. Such an arrangement can ensure that the body is not accidentally disconnected from the base during use of the mount. Furthermore, the Applicant has realised that an interlocking arrangement may also be exploited to make the body rotatable relative to the base. In other words, the interlocking arrangement can advantageously provide a dual function. It is therefore preferable that the interlocking arrangement allows for rotation of the body about a vertical axis passing through the base. This may be achieved in various ways, but in a set of embodiments the interlocking arrangement comprises a rotational ratcheting arrangement. This is described further below.
In addition, or alternatively, it is preferable that the mount further comprises means actuable to fix the interlocking arrangement and thereby disable rotation of the body. Again, this provides a dual function in terms of fixing the body in place on the base and simultaneously fixing the body in a given rotational position. Such means may be actuated, e.g. by a user when the body is connected to the base in a desired rotational position. Suitable means may comprise an actuator that applies a force to the interlocking arrangement to reinforce its positive interlock. In addition, or alternatively, suitable means may comprise an actuator that applies a force to prevent any relative movement in the interlocking arrangement.
It is desirable for a user to be able to disconnect the body from the base of the mount. Preferably the interlocking arrangement can be selectively released to enable disconnection of the body from the base. For example, it may be possible to move part of the interlocking arrangement out of positive engagement e.g. by a user pressing or pushing on a part of the interlocking arrangement. This is described further below.
Preferably the body is rotatable about a vertical axis passing centrally through the base. The interlocking arrangement may therefore be positioned centrally on the base. The interlocking arrangement preferably allows for rotation of the body substantially through a range of 360°. The interlocking arrangement may therefore be rotationally symmetric. As is mentioned above, the interlocking arrangement may comprise a rotational ratcheting arrangement. This may take the form of a one-way or two-way ratcheting arrangement.
In a preferred set of embodiments the interlocking arrangement comprises a toothed disc on the base and a corresponding set of teeth on the body (or vice versa). A positive engagement between the toothed disc on one side and the teeth on the other side forms the connection between the body and the base. Furthermore, the teeth are preferably mounted to allow a degree of movement relative to the toothed disc. The teeth may be mounted so as to be moveable radially and/or tangentially in the horizontal plane of the base and its toothed disc. This means that the body can be rotated relative to the base (or vice versa). For example, the teeth may be mounted on a slider. In addition, a resilient, e.g. spring, bias is preferably arranged to return the moveable teeth to a neutral position after each increment of rotational movement.
It is further preferable that the interlocking arrangement comprises a seal between the toothed disc and the set of teeth. Such a seal can help to accommodate some movement of the teeth out of the horizontal plane of the base without losing the positive connection between the body and the base. The seal may comprise an elastomeric and/or resilient and/or compressible surface or material, e.g. a silicone insert. Such a seal can help to hold the mount body firmly in position on the base, even when the body is rotated relative to the base during use.
As is described above, the mount may include means actuable to fix the interlocking arrangement and thereby disable rotation of the body. It will be appreciated that the body may be locked in a desired rotational position by preventing movement of the teeth relative to the toothed disc. Accordingly, an actuator may be arranged to apply a force to the spring-mounted teeth.
A further advantage of the interlocking arrangement comprises a toothed disc on the base and a corresponding set of teeth on the body is that the body can be connected to the base in a compact manner. In a preferred set of embodiments the body comprises an aperture to accommodate the toothed disc when the body is connected to the base in use. The toothed disc of the base may thereby share a horizontal plane with the body, helping to make the mount low in profile. Further preferably the aperture also accommodates the mounting portion when it is lowered to a position in the horizontal plane. Reference to the horizontal plane means in the same plane as the base, or a parallel plane. In other words, the mounting portion may be lowered to a position on top of the base where it is accommodated in the same aperture as the toothed disc. This means that the mount may not extend far out of the horizontal plane while still providing a high degree of adjustability.
This is considered novel and inventive in its own right, and thus according to a further aspect of the present invention there is provided a mount body comprising an aperture arranged to provide a removable connection to a fixed base and a mounting portion for supporting a camera in use, the mounting portion being pivotable from a lowered position where the mounting portion is accommodated by the aperture.
It will be appreciated that the mounting portion may be at least partly, but preferably substantially wholly, accommodated by the aperture in its lowered position. Such a mount body may further comprise any of the features already described above. For example, it is preferable that the aperture forms part of an interlocking arrangement, e.g. the mount body comprising teeth at a periphery of the aperture for positive engagement with a corresponding toothed disc. As above, such an arrangement can advantageously provide the removable connection to a fixed base and also rotation of the mount body relative to the fixed base.
In embodiments according to either aspect of the invention, preferably the mounting portion is pivotable from a lowered position in the horizontal plane of the body. As mentioned above, preferably this is a lowered position where the mounting portion is accommodated by an aperture in the body; this helps to keep the mounting body or mount low in profile. Preferably the mounting portion is pivotable away from the lowered position by up to at least 90°. The mounting portion may pivot relative to the body in any suitable way. Preferably the mounting portion has a hinged connection with the body. This can provide for smooth pivoting through a continuous range of angles.
It has already been discussed above that the mount body can preferably be locked in a desired rotational position. In addition, or alternatively, it is preferable for a user to be able to lock the mounting portion in a pivoted position as desired. It is therefore preferable that the mount or mount body further comprises means actuable to lock the mounting portion in a position. This may be in the lowered position or any position pivoted away from the horizontal plane of the aperture or base. Preferably this is the same as the means actuable to fix the interlocking arrangement and thereby disable rotation of the body relative to the base. In other words, a single locking actuator for both rotation and pitch of a camera supported by the mounting portion.
The present invention also extends to a camera comprising a mounting system that is supported on the mounting portion of an adjustable mount as described above. Typically the camera may be supported on the mounting interface in more than one orientation, e.g. forwards or backwards, which means that a 90° range of pitching is sufficient to cover all angles from the horizon.
It will be appreciated that a camera mounting system may be supported directly or indirectly by the mounting portion of the body, for example via an intermediate mounting interface. In a preferred set of embodiments the mounting portion comprises a mounting interface for a camera mounting system. This can allow a camera mounting system to be supported directly on the mounting portion. In at least some embodiments the mounting interface comprises one or more protruding T-bar features that mate with one or more corresponding apertures in a camera mounting system. In addition, or alternatively, the mounting interface may comprise one or more portions formed of a compressible material.
There will now be described some general features that may be applied to any of the embodiments discussed above. Preferably the mount, i.e. both the mount body and mount base, is made of a hard plastics material. As already mentioned, it is preferable that the mount has a low profile comprising a height that is much less than a width and a depth in the horizontal plane. The height of the mount may be measured as its dimension orthogonal to the horizontal plane of the base. The base is preferably substantially planar. However the base may comprise a flat or curved lower surface. This can assist in fixing the base to a range of different objects, e.g. a helmet or handlebars of a bicycle. The mount may consist of one or more of: an adhesive mount, a strap mount, a chest mount, a tripod mount, a tripod adapter, a suction cup mount, a helmet mount, a board mount, a magnetic mount, a ball joint mount, a tongue and groove mount, a strap mount, a goggle mount, an arm mount, an articulated mount, a telescoping arm, or an adaptor for retrofitting to any other kind of mount. It will be appreciated that the adjustability of the two-part mount, and the ability to interchange the mount body with different mount bases, make for a universal mount.
Various aspects of the teachings of the present invention, and arrangements embodying those teachings, will hereafter be described by way of illustrative example with reference to the accompanying drawings, in which:
