  • Patent number: 10602075
    Abstract: In some embodiments, an image capture device receives a capture command to capture an image. Exposure adjustment operations are subsequently performed. These operations include determining that a first luminance indicated by first image data, which is obtained using a first exposure value, exceeds a threshold luminance. The operations also include decreasing, based on the threshold luminance being exceeded, the first exposure value to a second exposure value. The operations also include determining, from second image data obtained using the second exposure value, that a second luminance indicated by the second image data is less than the threshold luminance. The HDR setting of the image capture device is configured to include a bracket of exposure values, where the second exposure value is a minimum exposure value from the bracket of exposure values. The image capture device executes a capture operation in which an image bracket is captured using this HDR setting.

  • Patent number: 10539791
    Abstract: Split exit pupil (or split eye-box) heads-up display (HUD)systems and methods are described. The described HUD system methods make use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall HUD volumetric aspects. A HUD module utilizes a high brightness small size micro-pixel imager to generate one or more HUD virtual images with a one or a plurality of given viewing eye-box segment sizes. When integrated together into a HUD system, a multiplicity of such HUD modules displaying the same image would enable such an integrated HUD system to have an eye-box size that is substantially larger than the eye-box size of a HUD module. The resultant integrated HUD system volume is substantially volumetrically smaller than a HUD system that uses a single larger imager.
