Navid SARHANGNEJAD has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11856301
    Abstract: There is provided a method and system for extending image sensor dynamic range using coded pixels. The method including: providing pixel codes to pixels in the photodetector array for each subframe of a frame; receiving a sensor readout of each of the pixels in the photodetector array for each subframe; for each subframe, based on the pixel code, routing each sensor readout value for collection at one or more taps or to a drain; combining the collected sensor readout values at each of the taps to determine a single pixel value for the frame; and outputting the single pixel value for each pixel for the frame.
    Type: Grant
    Filed: June 19, 2020
    Date of Patent: December 26, 2023
    Assignee: THE GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTO

  • Publication number: 20220116556
    Abstract: There is provided a method and system for pixel-wise imaging of a scene. The method including: receiving a pixel-wise pattern, the pixel-wise pattern including a masking value for each pixel in an array of pixels of an image sensor; producing an electronic signal at each pixel when such pixel is exposed to light received from the scene; and directing the electronic signal at each pixel to one or more collection nodes associated with such pixel based on the respective masking value, the one or more collection nodes each capable of integrating the received electronic signal.
