  • Patent number: 10007337
    Abstract: A device for acquiring a combined eye gaze image of an object under dark-eye effect conditions, with a first camera, a second camera, a first light source and a second light source being located on opposite sides of, and on essentially equal distance to a central optical axis. A control unit is arranged to acquire the combined eye gaze image by capturing, in a first point in time, a first frame of the object with the first camera with the second light source activated, and, at a second point in time, capturing a second frame of the object with the second camera with the first light source activated. The device comprises no additional light sources further away from the central optical axis than the first location and the second location. The device is thereby designed as compact as possible while a sufficient eye gaze tracking accuracy and robustness is maintained.

  • Patent number: 9979906
    Abstract: An optical system and method may relate to capturing extended dynamic range images. In an example embodiment, the optical system may include a lens element configured to receive incident light and a beam splitter optically coupled to the lens element. The beam splitter is configured to separate the incident light into at least a first portion having a first photon flux and a second portion having a second photon flux. The first photon flux is at least an order of magnitude greater than the second photon flux. A controller may be configured to cause a first image sensor to capture a first image of the first portion of the incident light according to first exposure parameters and cause a second image sensor to capture a second image of the second portion of the incident light according to second exposure parameters.

  • Patent number: 9888184
    Abstract: A light emission control device that is capable of controlling an emission amount of a light emitting unit irrespective of existence of a high-intensity light source. A selecting unit divides each of a non-emission image and a pre-emission image into a predetermined number of block areas, and selects a light-control target area according to a difference between luminance values in the non-emission image and the pre-emission image. A first weighting unit generates first weighting data by allocating a predetermined weight to each the light-control target area. A second weighting unit finds a weighting coefficient for each the light-control target area in the non-emission image, and to generate second weighting data by multiplying the first weighting data by the weighting coefficient. A control unit controls the emission unit according to a main emission amount that makes the light-control target area be proper exposure with reference to the second weighting data.

  • Patent number: 9860456
    Abstract: The embodiments described herein perform image infusion on Bayer image data that is coordinated with Clear image data captured with a dual camera. A first image sensor of the dual camera captures a Bayer image, while a second sensor captures a Clear image, where the first sensor and the second sensor are synchronized to capture the images at the same time. Some embodiments generate a relational mapping of Clear luma channel data extracted from the Clear image to Bayer luma channel data extracted from the Bayer image data, and use the relational mapping to generate multiple de-noised luma representations associated with the Bayer image. The multiple de-noised luma representations are then selectively merged together to generate a resultant image that retains a high signal-to-noise radio (SNR) and reduces artifacts obtained by the image processing.

  • Patent number: 9811892
    Abstract: Embodiments of the present disclosure generally relate to image signal processing logic, and in particular, to separating an undecimated image signal data to create two components with lower resolution and full-resolution, generating an interpolation guidance information based on the two components created by separation, forming a difference image data representing the difference between the chroma and luma values of each pixel and its neighboring pixels, and merging the processed image data from the processing pipelines with the unprocessed image data using the interpolation guidance information generated. The generation of the interpolation guidance information is based on determining distances between pixel values from a group comprising pixels from interpolation nodes, pixels diagonally located adjacent to the interpolation nodes, pixels horizontally adjacent to the interpolation nodes, and pixels vertically adjacent to the interpolation nodes.

  • Patent number: 9807321
    Abstract: An imaging device that reliably images an object flashing at a period closely analogous to an output period of a moving image within a certain period is provided. A first common frame image, which is synthesized from pixel signals produced by photoelectric conversion elements arranged in row selection lines from a second start row selection line to an end row selection line, is extracted from a first frame image synthesized by an image sensor starting at a first start row selection line. As a moving image, a sequence of the first common frame images and second frame images synthesized by the image sensor starting at the second start row selection line is produced. Due to the phase difference between an imaging period of the first common frame image and an imaging period of the second frame image, a flashing object is captured in any of the frame images.
