An electronic device includes at least one optical lens assembly. The optical lens assembly includes four lens elements, and the four lens elements are, in order from an outside to an inside, a first lens element, a second lens element, a third lens element and a fourth lens element. The first lens element has an outside surface being convex in a paraxial region thereof. The second lens element has an inside surface being convex in a paraxial region thereof. The fourth lens element has an inside surface being concave in a paraxial region thereof, wherein at least one of an outside surface and the inside surface of the fourth lens element includes at least one critical point in an off-axis region thereof.

A heat trace region extraction device includes an information output unit 181 that outputs information indicating a heat trace region which is a region of a trace of heat, extracted based on an actual object image which is an image of an actual object, obtained by photographing a certain range with an actual object camera for photographing the actual object and a thermal image which is an image of the heat emitted by the actual object, obtained by photographing a certain range with a thermal camera for photographing the heat emitted by the actual object.

The information output unit 181 displays information indicating the heat trace region on a transmissive display so that the heat trace region existing in the certain range and information indicating the heat trace region displayed on the transmissive display are aligned with each other.

A micro-OLED display includes a substrate with a coating made of IR-transparent material such as Zinc Selenide or Zinc Sulfide to allow a pupil tracking camera, which may include photodiodes, to be mounted directly behind the display. The coating is transparent to near infrared (NIR) radiation but opaque to visible light.

Embodiments of the present application disclose an image dehazing method and an image acquiring apparatus implementing image dehazing. In the embodiments of the present application, an RGBIR sensor can be adopted to generate a first RGBIR image and a second RGBIR image, such that the generated images are color images and contain infrared information; thus a finally generated image thus has a good dehazing effect; in addition, the image acquiring apparatus adjusts the first exposure time length and the second exposure time length based on the first RGBIR image and the second RGBIR image generated during each exposure, causing the RGB components and the IR component in the image to be balanced, which guarantees the display effect of the finally generated dehazed image.
