An image processing device a camera and a method for of encoding images captured by a camera are disclosed. For each image of an image sequence captured by the camera, the image is pre-processed by filtering the image by applying a privacy filter, the privacy filter being configured to distort the image in such a way that privacy is achieved in the filtered image, and, for at least a subset of the filtered images, by colour revising the filtered image by changing colour of pixels of a plurality of scattered areas of the filtered image such that a respective colour of one or more pixels of each area of the plurality of scattered areas represents one or more original colours of one or more pixels before filtering at a location of that area in the filtered image. The pre-processed images are then encoded into an encoded video stream.

Device and a method of encoding images including a privacy filter

A method for anonymizing a digital colour image comprising obtaining the digital colour image, and applying a linear random function to a respective colour vector representing colour components of a respective pixel of the digital colour image to obtain a monochrome image. The linear random function varies over the pixels of the digital colour image, and is further dependent on at least one random parameter.

Method and image-processing device for anonymizing a digital colour image

There is provided a camera and a method therein for facilitating installation of the camera. The method comprises capturing a video stream of a scene when the camera is installed with a first FOV, which scene comprises an object. A size in the video stream of at least one part of the object is estimated. As long as the estimated size is above a first threshold and below a second threshold, providing a first, edge-filtered, version of the video stream to secure privacy of the object. In response to the estimated size being above the second threshold indicating that the privacy is at risk of being revealed, entering an enhanced secure privacy mode comprising generating an alert to prompt an installer to re-install the camera with a second FOV different from the first FOV, and disabling provision of the first, edge-filtered, version of the video stream.

Camera and a method therein for facilitating installation of the camera

The present invention discloses a method of injecting additional data in one or more image sensor frames in an image sensor device. The method comprises: providing () additional data in the form of a numeric sequence, controlling () the lengths of subsequent blanking intervals in one or more image sensor frames to represent the numeric sequence, and transmitting the one or more image sensor frames from the image sensor device. The one or more image sensor frames may be transmitted to an image processor (). Examples of image processors () and a system () comprising an image processor () are also disclosed.

Method of injecting additional data

A device and method for providing additional functionality to an apparatus having a network connector by which the apparatus is configured to be connected to a network and to be allocated an identifier in the network, wherein the device is adapted to be connected between the network and the apparatus, wherein the device is configured to communicate with the network using a first network portion, wherein the device is configured to communicate with the apparatus using a second network portion, wherein logic circuitry of the device is accessible in the network via the apparatus using the second network portion. The device may be found in a system.

Device, system and method for providing additional functionality to an apparatus

The present application relates to methods and systems for including sensor data from a sensor unit () as an overlay () in a video stream from a camera () monitoring a scene (). The overlay has overlay regions (-) corresponding to scene regions (-), and when the sensor unit detects motion in a scene region a graphical element () is added to the overlay in the overlay region corresponding to that scene region. Video analytics procedures, such as object feature detection or motion or change detection may then be used to determine if detection has been made in a specific scene region by both the camera and the sensor unit.

Monitoring methods and devices

A monitoring camera includes a camera lens, an image sensor, and a housing enclosing the image sensor. The housing encloses a volume of Phase Changing Material (PCM) having the characteristic of not beginning a phase change until its temperature rises above a predetermined phase changing temperature. The phase changing temperature is in the range of 20-80 degrees Celsius, and the PCM is arranged to enclose the camera lens.

Monitoring camera

A pan-tilt camera is arranged to include a camera head, a stationary unit, an intermediate member arranged between the camera head and the stationary unit, a first rotary joint rotatably connecting the camera head to the intermediate member, and a second rotary joint, rotatably connecting the intermediate member to the stationary unit. A communication path is provided between the camera head and the stationary unit, including an optical waveguide arranged between the camera head and the stationary unit. The optical waveguide has a first end positioned at the first rotary joint to receive light from the camera head through the first rotary joint. The other end of the waveguide is positioned at the second rotary joint and is arranged to send light to the stationary unit through the second rotary joint.

Pan-tilt camera

Surveillance camera comprising a camera housing and a transparent view port cover, the camera housing including a top surface and a side surface, the side surface is extending along the periphery of the top surface is connected to the top surface, the transparent view port cover is asymmetrically arranged on the camera housing, is arranged to cover an opening in the camera housing, is curved, and is protruding over the top surface of the camera housing.

Surveillance camera

The invention relates to a network camera comprising an image acquisition part, an image processing part, a flat cable connecting the image acquisition part with a first end of the image processing part, and an inlet for an external data cable arranged at a second end of the image processing part. The image acquisition part is tiltable around a first axis in relation to the image processing part, the image processing part and the image acquisition part in combination are rotatable around a second axis, and the first and second axes are essentially perpendicular to each other.

Network camera assembly

Camera

A housing for an electronic device. The housing includes a first shell at least partly enclosing the electronic device, a second shell, and at least a first fan. The first shell is arranged to allow a gaseous fluid to surround the electronic device. The second shell at least partly encloses the first shell, and is arranged in relation to the first shell such that the gaseous fluid may be present between the shells. The at least first fan is arranged in an opening of the first shell such that it is capable of providing a flow of the gaseous fluid through the opening in the first shell of the gaseous fluid to the second shell and thereby provide heat transport from the electronic device to the second shell.
