  • Patent number: 9578265
    Abstract: A method of acquisition of an image may include accumulating electrical charges by a photosensitive element of a pixel circuit of an image sensor during a first period, transferring the electrical charges accumulated during the first period to a first electrical charge storage region of the pixel circuit, and at the end of the transfer of the electrical charges, accumulating the electrical charges by the photosensitive element during a second period. The method may further include transferring the electrical charges accumulated during the second period to a second electrical charge storage region of the pixel circuit, successively transferring the electrical charges stored in the first and second storage regions to a common reading node of the pixel circuit, acquiring two images from electrical charges transferred to the reading node from the first and second storage regions, respectively, and combining the two images acquired into a resultant image.

  • Patent number: 8878903
    Abstract: The disclosure relates to a method for reconstruction of a three-dimensional image of an object. A first image is acquired of the object lit by a luminous flux having, in a region including the object, a luminous intensity dependant on the distance, with a light source emitting the luminous flux. A second image is acquired of the object lit by a luminous flux having, in a region including the object, a constant luminous intensity. For each pixel of a three-dimensional image, a relative distance of a point of the object is determined as a function of the intensity of a pixel corresponding to the point of the object in each of the acquired images.
