Abstract: A method and an image processing device for detecting a portion of an image that is dominated by infrared (IR) light of at least one predetermined IR wavelength are disclosed. A set of phase pixel values for setting focus in the image is obtained. Each of the phase pixel values is compared to a first threshold related to phase shift occurring due to difference between at least a wavelength of the first colour component and said at least one predetermined IR wavelength. Moreover, in case a phase pixel value satisfies the first threshold, it is determined that the respective location associated with said phase pixel value is included in the portion of the image that is dominated by the IR light. A computer program and a computer program carrier are also disclosed.

Abstract: A Serial Peripheral Interface (SPI) master (110) and method therein for transferring data to a peripheral device in a data communication and processing system (100) are disclosed. The SPI master (110) comprises a memory (111) comprising a list of packets, each packet comprises data associated with a time parameter indicating at which time the data is to be transferred to the peripheral device. The time parameter is configurable. The SPI master further comprises a serial transmit and receive unit (112) to transfer the data in the list at a time according to the time parameter associated with the data.

Abstract: A technique for encoding a privacy masked image comprising a plurality of pixels into an encoded image frame of a video stream is disclosed, The technique includes receiving image data of the image, wherein the image data represents the pixel of the image, grouping the pixels of the image into encoding units, wherein each encoding unit comprises a plurality of neighboring pixels; receiving data defining a privacy mask masking part of the image in the interest of personal integrity, and graphical characteristics of the privacy mask including any one or a combination of constant coloring, smearing, and pixelization, identifying all encoding units having one or more pixels located within the privacy mask, extending the privacy mask to be aligned with the identified encoding units to form a redefined privacy mask covering the identified encoding units, generating a privacy masked image by applying the redefined privacy mask and the received graphical characteristics to the image, and encoding the privacy masked i

Abstract: A method and device for encoding a plurality of image frames uses two separate encoders, where each image frame is divided into two portions to each be encoded by one of the two encoders, where a boundary between the two portions is offset between the image frames according to a size of a search window of one of the encoders. Consequently, copying of pixel data for the purpose of motion search is only required in one direction between a first and a second encoder.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for displaying a video. A video stream including a plurality of image frames, wherein at least some image frames include an overlay, is received by a video management system. The video management system determines a position of the overlay within an image frame. The video management system applies an image adjustment function to the image frame to create an adjusted image frame. The image adjustment function uses the determined position of the overlay to adjust the image while keeping the appearance of the overlay essentially unchanged, and the video stream including the adjusted image frame is displayed.

Abstract: A camera assembly includes a housing and a transparent dome, and it is configured to receive at least one camera head arranged in the housing, inside the transparent dome. The housing comprises a cooling arrangement having a heat dissipation portion arranged within the housing and extending through the dome, and the heat dissipation portion is made from a material configured to transfer heat efficiently. Furthermore, the cooling arrangement comprises a channel for airflow.

Abstract: The present invention relates to a method and apparatus for visualizing information of a digital video stream is disclosed. The apparatus comprises: a memory arranged to store a series of merged image frames which is formed by merging groups of image frames of the digital video stream; a blending module arranged to blend multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and a display arranged to display the series of blended image frames.

Abstract: A method for remotely controlling a networked video camera includes sending an instruction message for the video camera, from the client to a communication controller, and determining whether the message is a candidate for being sent via a peer-to-peer connection. In response to the instruction message being determined not to be a candidate for being sent via a peer-to-peer connection, sending the instruction message from the communication controller to a camera control service, logging at the camera control service at least a portion of the instruction message, and sending the instruction message received at the camera control service from the camera control service to the video camera via the communication network. In response to the instruction message being determined to be a candidate for being sent via a peer-to-peer connection, the method further includes sending the instruction message via a peer-to-peer connection.

Abstract: A camera comprising a movable camera head, a transparent viewing window through which the camera head is arranged to capture images, and a heating arrangement for heating the viewing window is disclosed. The viewing window comprises an electrical conductor. The heating arrangement comprises an electrical contact device for contacting the conductor and applying an electric current to the conductor in a portion of the viewing window, thereby heating the conductor in the portion of the viewing window, and a movement device for movement of the heating arrangement in coordination with a movement of the camera head. A method of heating a viewing window of a camera is also disclosed.

Abstract: A method and a system for filtering thermal image data. The method comprises: capturing thermal image data by a thermal image detector; forming a signal distribution of intensity values; identifying a first part in the signal distribution of intensity values, the first part being a peak having an intensity width equal to or smaller than a predetermined intensity span being based on a resolution parameter of the thermal image detector; identifying a second part having an intensity width larger than the predetermined intensity span; determining an intensity range between the first part and the second part; and filtering, if the intensity range is larger than a predetermined minimum intensity range, the thermal image data by excluding thermal image data forming part of the first part.
