  • Patent number: 12088922
    Abstract: A method for processing an image. The method comprises receiving intensity values for each of a plurality of images captured by an image sensor during a detection window. The method comprises identifying, using the intensity values, one or more transitions occurring during the detection window, the one or more transitions each comprising a transition between an image in which a maximum clipping criterion is not satisfied and an image in which the maximum clipping criterion is satisfied. The method comprises, based on the identified transitions, at least one of: adjusting an exposure level of the image sensor; and determining a tonemapping function having a tonemapping strength, and applying the tonemapping function to the intensity values of a current image to generate tonemapped intensity values, wherein the image sensor has a current exposure level when the current image is captured.

  • Publication number: 20240073539
    Abstract: A method for adjusting an exposure level of an image sensor. The method comprises receiving intensity values of a current image captured by the image sensor, the image sensor having an initial exposure level when the current image is captured. The method comprises determining an intensity status based on comparing at least one characteristic of at least the current intensity values to one or more criteria. The method comprises selecting an exposure convergence mode, from a plurality of exposure convergence modes, based on the intensity status. The method comprises calculating, based on the current intensity values and the exposure convergence mode, a new exposure level for use by the image sensor in capturing a subsequent image.

  • Publication number: 20240064415
    Abstract: A method for processing an image captured by an image sensor. The method comprises receiving first pre-tonemapped intensity values of a first image captured by the image sensor. The method comprises applying a first tonemapping function having a first tonemapping strength to the first pre-tonemapped intensity values to generate first tonemapped intensity values. The method comprises receiving second pre-tonemapped intensity values of a second image captured by the image sensor, the second image captured subsequent to the first image. The method comprises, based on a difference between the first tonemapped intensity values and a target for the first tonemapped intensity values, determining a second tonemapping function having a second tonemapping strength. The method comprises applying the second tonemapping function to the second pre-tonemapped intensity values to generate second tonemapped intensity values.
