20100102206 | NEAR INFRARED/COLOR IMAGE SENSOR - A near infrared/color photodetector made in a monolithic form in a lightly-doped substrate of a first conductivity type covering a holder and comprising a face on the side opposed to the holder. The photodetector includes at least first and second photodiodes for the storage of electric charges photogenerated in the substrate, the second photodiode being adjacent to said face; and a first region extending at least between the second photodiode and the holder, preventing the passage of said charges between a first substrate portion being located between said region and the holder and a second substrate portion extending between said face and the first region, the first photodiode being adapted to store at least charges photogenerated in the first substrate portion and the second photodiode being adapted to store charges photogenerated in the second substrate portion. | 04-29-2010 |
20100289101 | IMAGE SENSOR - An image sensor including an array of pixels, wherein each pixel includes, in a vertical stack: a central photosensitive area; a stack of interconnects on top of the periphery of the photosensitive area, extending upwards up to a first height; a filtering layer on top of the photosensitive area, extending upwards from a height lower than the first height; and a microlens overlying the filtering layer in vertical projection, the optical axis of this microlens being such that the light rays received by the pixel reach the photosensitive area, substantially at its center. | 11-18-2010 |
20110073976 | BACK-SIDE IMAGE SENSOR - A color back-side illuminated image sensor including, on the side of the thin semiconductor layer opposite to the illuminated surface, periodic thickness unevennesses forming an optic network having characteristics which make it capable of reflecting a given wavelength chosen within the range of the wavelengths of an illuminating incident beam. | 03-31-2011 |
20120092459 | METHOD AND DEVICE FOR RECONSTRUCTION OF A THREE-DIMENSIONAL IMAGE FROM TWO-DIMENSIONAL IMAGES - 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. | 04-19-2012 |
20120147230 | METHOD FOR CHARACTERIZING PIXELS OF AN IMAGE SENSOR - A method for characterizing image sensor pixels arranged in an array, including the steps of: (a) illuminating a first portion of the array formed of pixels associated with a color filter of a first color; (b) measuring the detection performed by a central pixel of the first portion; (c) illuminating a second portion of the array formed of a central pixel associated with a color filter of a second color and of peripheral pixels associated with a color filter of the first color; (d) measuring the detection performed by the central pixel and the peripheral pixels of the second portion; (e) comparing the measurements of steps (b) and (d). | 06-14-2012 |
20120161269 | LOW-CROSSTALK FRONT-SIDE ILLUMINATED IMAGE SENSOR - A front-side illuminated image sensor, including photodetection regions, charge transfer elements, and an interconnection stack, all formed at the surface of a semiconductor substrate, microcavities being formed in the interconnection stack in front of the photodetection regions, microcavities being filled with materials forming color filters including metal pigments, regions of a material forming a barrier against ionic diffusion extending on the lateral walls of the microcavities. | 06-28-2012 |
20120162391 | THREE-DIMENSIONAL IMAGE SENSOR - An integrated image sensor capable of determining the distance to objects contained in a scene, including a pixel array, each pixel in the array being associated with a microlens and being formed of an assembly of sub-pixels, each including a photosensitive area. | 06-28-2012 |
20120162410 | 3D IMAGE SENSOR - An integrated image sensor capable of determining the distance to objects contained in a scene including at least a set of first pixels and a set of second pixels, the first and second pixels being alternately distributed in an array, the first pixels having a different angular aperture than the second pixels. | 06-28-2012 |
