Publication number: 20240397225Abstract: An image sensor may perform hybrid pixel binning. In pixel binning, pixel values from multiple pixels are combined into a single representative binning value. In a hybrid pixel binning scheme, different pixel groups may be binned in different ways in a single image sensor. When the range of values in a pixel group is low (indicating a flat surface), a mean or median binning scheme may be used. When the range of values in a pixel group is high (indicating an edge), a spatial weighting binning scheme may be used. When a pixel group has an intermediate range, a blend of the median/mean and spatial weighting may be used to avoid undesired blinking in the binning output. The hybrid binning scheme may reduce noise while still preserving high-frequency detail.Type: ApplicationFiled: May 22, 2023Publication date: November 28, 2024Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Kai Yau MOK, Marko MLINAR

Publication number: 20230314615Abstract: A time-of-flight (TOF) sensing system may include an illumination module and a sensor module. The sensor module may include an array of sensor pixels, each sensor pixel configured to perform multiple measurements to generate corresponding pixel data for a TOF sensing operation. Signal processing circuitry may generate phase data based on the pixel data. Phase denoise circuitry in the signal processing circuitry may perform different types of filtering operations on the phase data such as perform two bilateral filters of varying strengths. The lower-fidelity denoised phase data may be used for depth disambiguation, while the higher-fidelity denoised phase data may be used for depth calculation. If desired, the phase denoise circuitry may perform averaging operations for one or both of these filtering operations using a Cartesian coordinate representation and efficiently using piecewise linear trigonometric approximations.Type: ApplicationFiled: February 15, 2022Publication date: October 5, 2023Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Marko MLINAR

Patent number: 10931902Abstract: An image sensor may include a non-rectilinear image pixel array, which may produce non-rectilinear image data. The image sensor may include a resampling circuit to convert the non-rectilinear image data into rectilinear image data that is optimized for displaying an image to a user. This image data may be corrected using defect correction circuitry, resilience filtering circuitry, and aberration correction circuitry in the image sensor, and demosaicking circuitry and color correction circuitry in an image signal processor that is coupled to the image sensor. Alternatively, the non-rectilinear image data may be sent to the image signal processor without converting it to rectilinear image data. For example, machine vision applications may use and interpret non-rectilinear image data directly.Type: GrantFiled: May 8, 2018Date of Patent: February 23, 2021Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Marko Mlinar

Patent number: 10708524Abstract: Various embodiments of the present technology comprise a method and apparatus for high dynamic range imaging. According to various embodiments, the method and apparatus for high dynamic range imaging is configured to select the “best” signal for each pixel location to construct an HDR output. In one embodiment, the “best” signal is select among various pixel signals and the pixel signal selected as the “best” signal is based on the value of the pixel signals and identification of non-saturated. If only one pixel value for a particular pixel location is non-saturated, then the “best” signal is the non-saturated signal. If more than one pixel value is non-saturated, then the “best” signal is the pixel signal with the greatest value. If two more pixel values are non-saturated and both have equally great values, then the “best” signal is the pixel signal with the shortest integration time.Type: GrantFiled: July 23, 2018Date of Patent: July 7, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Marko Mlinar, Simon Srot

Patent number: 10609361Abstract: An imaging system may include an image sensor, a lens, and layers with reflective properties, such as an infrared cut-off filter, between the lens and the image sensor. The lens may focus light from an object in a scene onto the image sensor. Some of the light directed onto the image sensor may form a first image on the image sensor. Other portions of the light directed onto the image sensor may reflect off of the image sensor and back towards the layers with reflective properties. These layers may reflect the light back onto the image sensor, forming a second image that is shifted relative to the first image. Depth mapping circuitry may compare the first and second images to determine the distance between the imaging system and the object in the scene.Type: GrantFiled: June 29, 2018Date of Patent: March 31, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Marko Mlinar, Ulrich Boettiger

Publication number: 20200020730Abstract: An image sensor may include pixels having nested sub-pixels. A pixel with nested sub-pixels may include an inner sub-pixel that has either an elliptical or a rectangular light collecting area. The inner sub-pixel may be formed in a substrate and may be immediately surrounded by a sub-pixel group that includes one or more sub-pixels. The inner sub-pixel may have a light collecting area at a surface that is less sensitive than the light collecting area of the one or more outer sub-pixel groups. Microlenses may be formed over the nested sub-pixels, to direct light away from the inner sub-pixel group to the outer sub-pixel groups in nested sub-pixels. A color filter of a single color may be formed over the nested sub-pixels. Hybrid color filters having a single color filter region over the inner sub-pixel and a portion of the one or more outer sub-pixel groups may also be used.Type: ApplicationFiled: September 26, 2019Publication date: January 16, 2020Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Marko MLINAR, Ulrich BOETTIGER, Richard MAURITZSON
