  • Publication number: 20230397357
    Abstract: A cable retention arrangement for an electronic device, such as a surveillance camera, comprises a base member and an attachment member releasably attachable to the base member. The base member is provided with a channel configured to receive a cable and arranged in a surface of the base member configured to face the attachment member in an assembled state of the cable retention arrangement in which the attachment member is attached to the base member. The channel extends between a cable entry and a cable exit and the attachment member is provided with a slit which, in the assembled state of the cable retention arrangement, is configured to extend in a direction traversing the channel such that the cable exit of the channel is defined at the intersection of the channel and the slit. The disclosure further relates to an electronic device comprising such a cable retention arrangement.

  • Patent number: 11683575
    Abstract: An image system (100) comprising a camera (110), a control unit (120), a processing unit (130), one or more illumination devices (140). The image system (100) is configured to obtain a distance matrix for a scene. Each cell of the distance matrix corresponds to a zone of the scene and a value in each cell represents the distance from an object in the zone to the camera. The image system is further configured to obtain an illumination intensity matrix for the scene. Each cell of the illumination intensity matrix corresponds to a zone of the scene and a value in each cell represents illumination intensity of one or more illumination devices in each zone of the scene. The image system is further configured to generate a compensation matrix based on the illumination intensity matrix and the distance matrix and generate an image of the scene based on the compensation matrix.
