A camera lens can be subject to lens flare due to light reaching a camera sensor from outside of the camera field of view. When an electronic device size is reduced such that a lens cannot be recessed relative to the device housing, the lens can capture stray light. To reduce the chance that stray light reaches the lens and sensor, the lens can be treated with a photochromatic treatment. Properties of the photochromatic treatment, as well as the distribution of the treatment can be selected to reduce lens flare caused by particular types of light. In some embodiments, a photochromatic treatment can instead or in addition be applied for a cosmetic purpose. For example, a photochromatic treatment can be applied to a device housing, icons or text displayed on the device enclosure, on a mask within a device display window, or any other electronic device enclosure component.

The invention discloses a lens flare drawing method and device. Texture mappings required by a plurality of lens flares are combined into a big texture mapping, and the big texture mapping is submitted to the cache of a graphics processing unit; then, in a three-dimensional scene, a flare model is established; according to the input parameters of a plurality of lens flares and a current scene, the attribute of each lens flare is regulated in real time; according to the attribute of each lens flare, a quadrangular surface patch is called to read a big texture mapping cache; and each lens flare is drawn through a shader. By use of the scheme, a picture mapping way is used for drawing the lens flare, and a plurality of lens flares can be drawn in one batch through the quadrangular surface patch and the big texture mapping to save drawing expenditures. In addition, the parameters of the lens flares can be set and input by design personnel, so that the parameters have diversified styles and are flexible in configuration, and the problems that existing lens flare drawing is high in expenditure and can not be configured are solved.

The invention provides a car light, wherein, a plurality of anti-dazzle devices opposite to a bulb are arranged in a lampshade which is connected with a light shell into a whole. The invention can effectively reduce the light which radiates to the side through the anti-dazzle devices arranged in the lampshade, increases direct spot light, removes the lens flare generated when meeting, and is applicable to various automobiles and motorcycles.

Light-absorbing flange lenses that may be used in the lens stacks of compact lens systems. In a light-absorbing flange lens, the effective area of the lens is composed of a transparent optical material, and at least a portion of the flange of the lens is composed of an optical material that absorbs at least a portion of the light that enters the flange. Using light-absorbing flange lenses may allow the lens barrel to be eliminated from the lens system, thus reducing the X-Y dimensions of the lens system when compared to conventional compact lens systems that include a lens stack enclosed in a lens barrel. In addition, using a light-absorbing material in the flanges of the light-absorbing flange lenses may reduce or eliminate optical aberrations such as lens flare, haze, and ghosting in images.
