  • Publication number: 20170332000
    Abstract: A high dynamic range light-field image may be captured through the use of a light-field imaging system. In a first sensor of the light-field imaging system, first image data may be captured at a first exposure level. In the first sensor or in a second sensor of the light-field imaging system, second imaging data may be captured at a second exposure level greater than the first exposure level. In a data store, the first image data and the second image data may be received. In a processor, the first image data and the second image data may be combined to generate a light-field image with high dynamic range.

  • Publication number: 20170059305
    Abstract: A depth map may be generated in conjunction with generation of a digital image such as a light-field image. A light pattern source may be used to project a light pattern into a scene with one or more objects. A camera may be used to capture first light and second light reflected from the one or more objects. The first light may be a reflection of light originating from one or more other light sources independent of the light pattern source. The second light may be a reflection of the light pattern from the one or more objects. In a processor, at least the first light may be used to generate an image such as a light-field image. Further, in the processor, at least the second light may be used to generate a depth map indicative of distance between the one or more objects and the camera.

  • Patent number: 9420276
    Abstract: Microlens positions for a light-field capture device may be calibrated. A calibration light-field image may be captured, with a microlens portion corresponding to each microlens of the light-field capture device. Interstitial spaces between the microlens portions may be identified and used to locate one or more center locations of the microlens portions. The center locations may be used to generate a model that indicates the microlens positions. Additionally or alternatively, the calibration light field image may be used to select one or more contour samples from among multiple contour samples of the microlens portions. The contour sample may be fitted to a circle centered at a center location of a microlens portion to identify the center location, which may then be used to generate a model that indicates the microlens positions. Multiple iterations may be used to enhance the accuracy of the models.
