Lens flare refers to a phenomenon wherein light is scattered or flared in a lens system, often in response to a bright light, producing a sometimes undesirable artifact within the image. This happens through light scattered by the imaging mechanism itself, for example through internal reflection and scattering from material imperfections in the lens. Lenses with large numbers of elements such as zooms tend to exhibit greater lens flare, as they contain a relatively large number of interfaces at which internal scattering may occur. These mechanisms differ from the focused image generation mechanism, which depends on rays from the refraction of light from the subject itself.

Photochromatic coating for controlling lens flare
InactiveUS20110141336A1Reduce lens flareTelevision system detailsColor television detailsCamera lensLens flare
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.

Adjusting data for photographed images includes detecting a reference image in the data, where the reference image contains a detectable uniformity and adjusting the data according to the reference image. The reference image may be a uniform grid pattern of dots preprinted on paper. A paper type may be determined prior to adjusting the data according to the reference image. The paper type may be determined according to spacing and / or patterns of the dots, and / or layout of page areas covered with dots. Adjusting the data may include removing effects corresponding to a folded corner, a removed corner, an obstructed corner, lens flare spots, and / or a shadow. Positional coordinates of the data may be adjusted by normalizing the grid through a non-linear transformation that eliminates curvature of the grid and / or distortions based on perspective.

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.
