  • Patent number: 12081732
    Abstract: An image pickup apparatus includes an optical system, an image sensor configured to photoelectrically convert an optical image formed by the optical system and to output image data, an infrared cut filter movable between a first position at which the infrared cut filter is inserted into an optical path of the optical system and a second position at which the infrared cut filter is removed from the optical path of the optical system, and a control unit configured to determine, based on the image data, whether or not the infrared cut filter is located at a position different from each of the first position and the second position.

  • Patent number: 11218620
    Abstract: An imaging apparatus includes a casing including a base unit and a cover unit, a camera unit disposed on the base unit in the casing, a camera cover disposed on the base unit in the casing and being in contact with and covering the camera unit, and a biasing member configured to bias the camera cover and to be deformed by being pressed by the cover unit when the cover unit is attached to the base unit. A frictional force between the camera unit and the camera cover increases due to an increase in a biasing force applied from the biasing member to the camera cover according to the deformation of the biasing member.

  • Patent number: 11178316
    Abstract: A monitoring camera having a compound window arranged in a frame of a camera housing, and a camera head arranged inside the housing, is disclosed. The compound window has an inner transparent plate, closest to the camera head, and an outer protective window, arranged in a plane parallel to the transparent plate, on an outside thereof, and the compound window further comprises a heating arrangement arranged and configured to supply thermal energy to peripheral areas of the transparent plate. The transparent plate has a greater heat conductivity than the protective window and is arranged in close proximity to the protective window, so thermal energy will be transferred from the heating arrangement to the transparent plate and then efficiently transferred to the protective window.

  • Patent number: 10225634
    Abstract: An electronic apparatus includes a housing including a first opening through which sound is guided to a microphone, a waterproof sheet covering the first opening, and a holding member having a sound collection portion for collecting sound to the microphone between the holding member and the waterproof sheet. The holding member includes a first circular portion having a second opening through which the sound collection portion communicates with the housing, and holding the waterproof sheet between the first circular portion and the housing, and a second circular portion disposed concentrically about the first circular portion having a third opening through which the sound collection portion communicates with the inside of the housing, and holding the waterproof sheet between the second circular portion and the housing. The second opening and the third opening are disposed not to overlap on a plane parallel to the waterproof sheet in a radial direction.
