  • Publication number: 20180247106
    Abstract: Embodiments of the present disclosure include systems and methods for cell identification using a lens-less cell identification sensor. Randomly distributed cells can be illuminated by a light source such as a laser. The object beam can be passed through one or more diffusers. Pattern recognition is applied on the captured optical signature to classify the cells. For example, features can be extracted and a trained classifier can be used to classify the cells. The cell classes can be accurately identified even when multiple cells of the same class are inspected.

  • Patent number: 9928598
    Abstract: A depth measurement apparatus that calculates depth information of an object based on a first color image and a second color image. A depth calculator calculates depth information of a target pixel in a color plane, using the two color images. An evaluator calculates, for each color plane, an evaluation value to indicate a confidence coefficient of the depth information in the target pixel. The depth calculator (i) determines, based on the evaluation value, a color plane from which the depth information of the target pixel is calculated, (ii) calculates a correlation value in one color plane between the two color images, to calculate the depth information from the correlation value using a conversion table or a conversion formula that is different for each color plane, and (iii) calculates the depth information of the target pixel using a color plane of which a correlation value is a threshold or less.

  • Patent number: 9762788
    Abstract: An image pickup apparatus includes an imaging unit that acquires a first image by capturing an object at a first focusing position, and acquires a second image after acquiring the first image, by capturing the object at a second focusing position different from the first. The second image has different blur than the first image. A depth information determination unit determines depth information of the object on the basis of a difference in blur between the first image and the second image. A focusing position setting unit sets a focus movement amount that is a difference between the first focusing position and the second focusing position, in accordance with an F-number of the imaging unit. The second focusing position is set such that an absolute value of the focus movement amount is larger when the F-number is large, as compared to when the F-number is relatively small.

  • Patent number: 9576370
    Abstract: A distance measurement method for calculating distance information from a first image and a second image that are image-captured with different image-capturing parameters. A setting step sets a first local region located in the first image including a distance calculation target pixel, and a second local region located in the second image corresponding to the first local region. An extraction step extracts a plurality of shift regions, which are regions of which a shift amount from the second local region is within a predetermined range. A correlation value is calculated between the first local region and each of the plurality of shift regions. A decision step determines a correlation value used for calculating distance information, based on the plurality of correlation values calculated in the first calculation step. The distance information on the distance calculation target pixel is calculated, based on the correlation value determined in the decision step.
