Abstract: An image stabilization mechanism for a camera is provided. The mechanism comprises a movement sensor capable of sensing motion of the camera, an element in an optical path of the camera, a ball and a plate acting as a bearing allowing for the element to move in a plane orthogonal to the optical path, an actuator mechanism capable of moving the element in the plane, and a processor configured to control the actuator to move the element as a response to motion of the camera as detected by the movement sensor, thereby stabilizing images from the camera. Furthermore, the processor further is configured to move the element along a secondary motion path so as to distribute wear on the plate created by the ball, and the processor is further capable of compensating for an image shift created by the secondary motion path by other means for shifting the image.

Abstract: There is provided techniques for setting frame rates of a camera. The camera comprises a plurality of image sensors arranged to capture images to be stitched into a panorama image of a scene. Information of a respective angle between the optical axis of each of the plurality of image sensors and a direction along which a straight path structure, to be monitored by the camera, extends through the scene is obtained. The plurality of image sensors are divided into at least two groups as a function of the angles. All the angles of the image sensors within each of the at least two groups are part of its own continuous angle interval. One frame rate is set per each of the at least two groups. The frame rate decreases from the group with highest continuous angle interval towards the group with lowest continuous angle interval.

Abstract: The present teachings relate to the field of video encoding. In particular, the present teachings relate to a method, device, and system for encoding a sequence of frames wherein a motion level of image data of an initial frame in the sequence of frames is determined to be below a motion level threshold. The encoding method described herein may reduce the bit rate for the encoded sequence of frames, while avoiding that the encoded video stream looks unnatural or frozen when decoded and displayed.
