  • Publication number: 20250259269
    Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths of fields. A method of processing image data includes obtaining a first image captured using an image sensor, the first image being associated with a first exposure: obtaining a second image captured using the image sensor, the second image being associated with a second exposure that is longer than the first exposure: modifying a first region of the first image based on a first transformation and a second region of the first image based on a second transformation to generate a modified first image; and generating a combined image at least in part by combining the modified first image and the second image.

  • Publication number: 20240354969
    Abstract: This disclosure provides systems, methods, and devices for image signal processing that support efficient motion estimation. In a first aspect, a method of image processing includes determining first and second sets of correlation parameters for respective first and second frames, generating a transform matrix indicating motion from the first frame to the second frame in accordance with the correlation parameters, and inverting the transform matrix to produce an inverted transform matrix. Other aspects and features are also claimed and described.

  • Patent number: 11825207
    Abstract: The present disclosure generally relates to exposure control for image capture devices. One example method generally includes receiving sensor data indicating a movement associated with an image capture device capturing a first frame and a second frame, wherein the first frame is associated with a higher exposure setting as compared to the second frame; predicting, based on the sensor data, a shift for aligning one or more features of the first frame and one or more features of the second frame; applying the shift to align the one or more features of the first frame and the one or more features of second frame; and generating a frame output at least in part by combining at least a portion of the first frame with at least a portion of the second frame.

  • Patent number: 11279284
    Abstract: A method for determining a state of a tailgate (9) of a pickup vehicle (1) by a camera system (2), includes capturing a cargo bed (5) of the pickup vehicle (1) in an image (8) captured by a camera (3), determining a first region of interest (ROI1) in the captured image (8) by an electronic computing device (4) of the camera system (2), wherein the first region of interest (ROI1) includes the potential tailgate (9) at least partially, determining a parameter optically characterizing the tailgate (9) depending on the captured image (8), analyzing the first region of interest (ROI1) with regard to the characterizing parameter, and determining a closed state of the tailgate (9) as state or determining an opened state of the tailgate (9) as state depending on the analysis of the first region of interest (ROI1). A computer program product, an electronic computing device (4) as well as a camera system (2) are also disclosed.
