  • Patent number: 10303920
    Abstract: Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

  • Publication number: 20150124460
    Abstract: A lens includes an optical axis, a light source recess arranged through the optical axis, a reflection surface crossing through the optical axis, and a critical reflection surface which is arranged in a spaced relationship with the optical axis. The critical reflection surface is arranged between the light source recess and the reflection surface and receives the light from the light source recess and the reflection surface and reflects the light from the light source recess and the reflection surface towards the reflection surface. The emission light of the lens is light emitted forward of the light emitting surface which is reflected via the reflection surface and the critical reflection surface. Therefore, people cannot receive directly light emitted forward of the LED after it cross through the lens. In result, high luminance light from the LED is prevented from ripping into eyes, which achieve the aim of anti-glare.
