1. A camera comprising:
a housing;
a first lens assembly comprising one or more lenses and having a first optical axis, the first lens assembly being configured to receive light from outside the camera and to transmit the light toward a mirror;
the mirror placed at a point of intersection of the first optical axis and a second optical axis and configured to receive the light from the first lens assembly and to reflect the light toward a second lens assembly;
the second lens assembly comprising one or more lenses and having the second optical axis, the second lens assembly being configured to receive the light from the mirror and to transmit the light toward an image sensor;
the image sensor placed on the second optical axis; and
an image stabilisation (IS) apparatus comprising:
a first detector configured to generate a first signal in response to a rotation of the camera about an axis perpendicular to both the first optical axis and the second optical axis;
a first actuator configured to rotate the first lens assembly relative to the housing about a first rotation axis by a first angle in response to the first signal and at the same time rotate the mirror about the first rotation axis by a second angle which is half of the first angle, wherein the first rotation axis is perpendicular to both the first optical axis and the second optical axis and passes through the point of intersection of the first optical axis and the second optical axis;
a second detector configured to generate a second signal in response to a rotation of the camera about an axis perpendicular to both the first rotation axis and the second optical axis; and
a second actuator configured to rotate the image sensor relative to the housing about the second optical axis.
