  • Publication number: 20150029386
    Abstract: Light-field image data is processed in a manner that reduces projection artifacts in the presence of variation in microlens position by calibrating microlens positions. Approximate centers of disks in a light-field image are identified, and gridded calibration is performed, by fitting lines to disk centers along orthogonal directions, and then fitting a rigid grid to the light-field image. For each grid region, a corresponding disk center is computed, and a displacement vector is generated. For each grid region, the final disk center is computed as the vector sum of the grid region's geometric center and displacement vector. Calibration data, including displacement vectors, is then used in calibrating disk centers for more accurate projection of light-field images. In at least one embodiment, the imaging geometry is arranged so that disks are separated by a gap, so as to limit or eliminate ghosting.

  • Publication number: 20140300646
    Abstract: According to various embodiments, a dolly zoom effect is generated using light field image data. The dolly zoom effect simulates an in-camera technique wherein a camera moves toward or away from the subject in such a way that the subject is kept at the same size throughout the effect. The effect causes the relative size of foreground background elements to change while foreground elements such as the subject remain the same size. By varying a parameter while projecting the light field image, the size of each object in the projection image scales depending on its relative depth as compared with the depth of the target subject, thus simulating the dolly zoom effect without any need to physically move the camera.

  • Patent number: 8831377
    Abstract: Light-field image data is processed in a manner that reduces projection artifacts in the presence of variation in microlens position by calibrating microlens positions. Initially, approximate centers of disks in a light-field image are identified. Gridded calibration is then performed, by fitting lines to disk centers along orthogonal directions, and then fitting a rigid grid to the light-field image. For each grid region, a corresponding disk center is computed by passing values for pixels within that grid region into weighted-center equations. A displacement vector is then generated, based on the distance from the geometric center of the grid region to the computed disk center. For each grid region, the final disk center is computed as the vector sum of the grid region's geometric center and displacement vector. Calibration data, including displacement vectors, is then used in calibrating disk centers for more accurate projection of light-field images.

  • Patent number: 8768102
    Abstract: According to various embodiments of the invention, improved downsampling techniques are employed, which can be applied to light field images and which preserve the ability to refocus (and otherwise manipulate) such images. Groups of pixels, rather than individual pixels, are downsampled; such groups of pixels can be defined, for example, as disks of pixels. Such downsampling is accomplished, for example, by aggregating values for pixels having similar relative positions within adjacent disks (or other defined regions or pixel groups) of the image. When applied to light field images, the downsampling techniques of the present invention reduce spatial resolution without sacrificing angular resolution. This ensures that the refocusing capability of the resulting light field image is not reduced and/or adversely impacted.

  • Patent number: 8267668
    Abstract: A fuel pump system for pumping fuel to an engine in a vehicle includes a pump motor having a carbon-based commutator and brushes in a position exposed to fuel, resulting in a tendency to form a film between the commutator and brushes that can reduce pump performance by increasing the electrical resistance of the brush-commutator interface. The pump motor has a nominal voltage rating. A power circuit is coupled to the pump motor for selectably providing an operating voltage and a boost voltage, wherein the boost voltage is greater than the nominal voltage rating. A controller selecting the operating voltage during an ordinary run cycle and selects the boost voltage during a clean-up cycle. The controller selects the clean-up cycle for a limited time that is sufficiently short to avoid damage to the pump motor from exceeding the nominal voltage rating and sufficiently long to create arcing between the commutator and brushes that reverses formation of the film.
