Abstract: Methods and apparatus, including computer program products, implementing and using techniques for reducing bitrate from a monitoring camera. A first input is received that identifies first regions of an image representing a camera field of view. The first regions contribute significantly to the bitrate. A second input is received that identifies second regions of the image. The second regions contain information that is deemed to be of little visual interest to a user of the monitoring camera. Third regions of the image are determined. The third regions are regions where the first and second regions overlap at least in part. Video encoder settings are applied to force skip blocks in at least some of the third regions, thereby reducing contributions to the bitrate from the third regions.

Abstract: A set of different pilot structures are designed for use in different environments and/or different user behaviours that are expected to occur in a cell. The radio conditions for a user are estimated. Each user is then assigned an area (108A-E) in resource space for its communication, which has a suitable pilot configuration. In one embodiment, the entire resource space is provided with different pilot structures in different parts (110A-D) In advance and allocation of resources to the users are then performed in order to match estimated radio conditions to the provided pilot structure. In another embodiment, allocation is performed first, and then the actual pilot structure is adapted within the allocated resource space area to suit the environmental conditions.

Abstract: The present invention relates to a method, an encoder, a computer program product, and a system for real-time encoding. The encoder is arranged to receive movement information about a movement of a camera, the encoder being arranged to encode, in real-time, a video stream acquired by the camera during the movement of the camera, wherein the encoder is arranged to encode based on said movement information. The movement information may be stored in a memory.

Abstract: Autofocusing a camera while zooming may include zooming the lens to a first zoom position, measuring a first object distance from the camera to an object on which to focus, determining a first focus start position using the first object distance, performing a first autofocus using the first focus start position as a starting point, thereby determining a first focus position. A first lookup object distance may be determined based on the first determined focus position. A first correction factor may be calculated as a ratio between the first lookup object distance and the first object distance. The lens may be zoomed to a second zoom position, and a second focus position may be determined using a second object distance based on the first object distance and a second correction factor based on depths of field at the second and first zoom positions.

Abstract: A method of autofocusing a camera during a zooming operation is disclosed, comprising zooming the lens to a first zoom position, measuring a first object distance from the camera to an object on which to focus, determining a first focus start position using the first object distance, performing a first autofocusing operation using the first focus start position as a starting point, thereby determining a first determined focus position. A first lookup object distance is determined based on the first determined focus position. A first correction factor is calculated as a ratio between the first lookup object distance and the first object distance. The lens is zoomed to a second zoom position, and a second focus position is determined using a second object distance calculated as a product of the first object distance and a second correction factor based on a ratio of depths of field at the second and first zoom positions.

Abstract: The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

Abstract: A method and mobile unit facilitate installation of a surveillance camera for monitoring an object of interest in a scene. The surveillance camera acquires a zoomed out image of the scene. The zoomed out image is displayed in a display wherein the zoomed out image has a zoomed out center point. An indicator overlaid on the displayed zoomed out image is displayed in the display, wherein the indicator and the zoomed out center point are displaced in relation to each other by a deviation. The indicator indicates the position of a zoomed in center point of a zoomed in image of the scene. The surveillance camera is directed so that the position of the object of interest and the indicator coincide so that the object of interest is included in a zoomed in image of the scene.
