  • Patent number: 10706572
    Abstract: Systems and methods for performing depth estimation may comprise: an illuminator capable of illuminating a scene from at least a first position and a second position, an image sensor to capture (i) a first image of the scene while the illuminator illuminates the scene from the first position and (ii) a second image of the scene while the illuminator illuminates the scene from the second position, and an image processor to receive the first and second images from the image sensor and estimate a depth of at least one feature that appears in the first and second images. The depth is estimated based on the relative intensity of the first image and the second image, a distance between the first illumination position and the second illumination position, and a position of the at least one feature within at least one of the first and second images.

  • Patent number: 8854515
    Abstract: A method for adaptive spectral image capture that may be performed via an image capture device is disclosed. A default capture parameter is applied to an imaging assembly and a sample image of a scene is captured by an image capture device. The sample image is analyzed to identify transition zones between multiple different regions. An initial guess as to which spectral regions a filter mode might work best is obtained based on dominant transition region spectrum and a first iterated step in which numerical values for the filter mode are calculated. A second iterated step in which each such filter mode is evaluated for effectiveness against other filter modes. The regions in which a specific filter mode works best becomes associated with the filer mode and these regions become the guess for the next iteration.

  • Patent number: 8760556
    Abstract: An image capture apparatus includes a variable translucency mirror, a viewfinder unit configured to receive light reflected by the variable translucency mirror, an imaging sensor configured to receive light transmitted through the variable translucency mirror, an image display unit configured to display an image based on the light received by the imaging sensor, and a controller configured to set a translucency of the variable translucency mirror. In a viewfinder mode, the controller sets the variable translucency mirror to be at least partially reflective such that light incident on the variable translucency mirror is reflected thereby and received by the viewfinder unit. In a display view mode, the controller sets the variable translucency mirror to be at least partially transparent, such that light incident on the variable translucency mirror is transmitted therethrough and received by the imaging sensor.

  • Patent number: 8717457
    Abstract: A spectral capture parameter is adjusted for capturing successive frames of motion image data. Spectral content in a first region of a current frame is compared to spectral content in a counterpart region in a previous frame. It is determined whether the spectral content has changed by more than a threshold value, based on the comparison. Responsive to a determination that the spectral content has changed by more than the threshold value, the spectral capture parameter for the first region is adjusted, and the adjusted spectral capture parameter is applied to an imaging system for capture of a successive frame.

  • Patent number: 8670609
    Abstract: Systems and methods for evaluating images segment a computational image into sub-images based on spectral information in the computational image, generate respective morphological signatures for the sub-images, generate respective spectral signatures for the sub-images, and generate a resulting image signature based on the morphological signatures and the spectral signatures.
