  • Patent number: 12293498
    Abstract: A video delivery system for luminance adjustment based upon a viewer adaptation state comprises a processor configured to: receive a source image including a current image frame including metadata corresponding to a mean luminance value of the current image frame, and the source image including an upcoming image frame including metadata corresponding to a mean luminance value of the upcoming image frame. The processor is configured to determine an ambient luminance value based on an ambient luminance, determine an incident luminance value based on the ambient luminance value and the mean luminance value, determine a difference between a current pupil size and a target pupil size, and generate an output image by modifying the source image based on a luminance adjustment factor, the luminance adjustment factor being a function of the difference between the current pupil size and the target pupil size.

  • Publication number: 20250133241
    Abstract: Tensor-Product B-splines (TPB) have been shown to improve video quality when used to represent reshaping functions to map reshaped standard dynamic range content into high dynamic range (HDR) content; however, TPB prediction is computationally intensive and may not be supported by legacy devices. Methods and systems for backwards-compatible signaling of TPB-related metadata and a fast TPB prediction method are presented to overcome both of these limitations. Computation overhead for a TPB-based 3D look-up table is reduced by using temporary two-dimensional arrays. A remapping of the most significant bits of a legacy bit-depth parameter allows for backwards compatibility.

  • Patent number: 12170815
    Abstract: The described embodiments include systems and methods for producing and adapting images, such as video images, for presentation on display devices that have various different aspects ratios, such as 4:3, 16:9, 9:16, etc. In one embodiment, a method for producing content, such as video images, can begin by selecting an original aspect ratio and determining, within at least a first scene in the content, a position of a subject in the first scene. In one embodiment, the original aspect ratio can be substantially square (e.g., 1:1). Metadata can then be created, based on the position of the subject in the first scene, to guide playback devices to asymmetrically crop the content, relative to the position, for display on display devices that have aspect ratios that are different than the original aspect ratio. Other methods and systems are also described.

  • Publication number: 20240397088
    Abstract: Methods and systems for generating and using dynamic spatial metadata in image and video processing are described. In an encoder, in addition to global metadata, local, spatial metadata for two or more image regions or image objects are generated, smoothed, and embedded as spatial metadata values. In a decoder, the decoder can reconstruct the spatial metadata and use interpolation techniques to generate metadata for specific regions of interest. Examples of generating spatial metadata related to min, mid, and max luminance values in an image are provided.

  • Publication number: 20240095893
    Abstract: A first reshaping mapping is performed on a first image represented in a first domain to generate a second image represented in a second domain. The first domain is of a first dynamic range different from a second dynamic range of which the second domain is. A second reshaping mapping is performed on the second image represented in the second domain to generate a third image represented in the first domain. The third image is perceptually different from the first image in at least one of: global contrast, global saturation, local contrast, local saturation, etc. A display image is derived from the third image and rendered on a display device.

  • Patent number: 11743550
    Abstract: Apparatus and methods for providing solutions to the problem of preserving original creative intent for video playback on a target display are presented herein. According to one aspect, a video bitstream includes metadata with a flag indicative of creative intent for a target display. This metadata may include numerous fields that denote characteristics such as content type, content sub-type, intended white point, whether or not to use the video in Reference Mode, intended sharpness, intended noise reduction, intended MPEG noise reduction, intended Frame Rate Conversion, intended Average Picture Level, and intended color. This metadata is designed to make it effortless for the content creators to tag their content. The metadata can be added to the video content at multiple points, the status of the flag is set to TRUE or FALSE to indicate whether the metadata was added by the content creator or a third party.

  • Patent number: 8582818
    Abstract: A method of automatically detecting objects in front of a motor vehicle comprises the steps of pre-storing template objects representing possible objects in front of the motor vehicle, detecting images from a region in front of the vehicle by a vehicle mounted imaging means, generating a processed image containing disparity or vehicle-to-scene distance information from the detected images, comparing the pre-stored template objects with corresponding regions-of-interest of the processed image, and generating a match result relating to the match between the processed image and the template objects. Each of the pre-stored template objects is a flat two-dimensional multi-pixel area of predetermined shape.

    Abstract: A vision method for automatically detecting objects in front of a motor vehicle, comprises the steps of detecting images from a region in front of the vehicle by a vehicle mounted imaging means; generating from said detected images a processed image, containing disparity or vehicle-to-scene distance information; comparing regions-of-interest of said processed image to template objects relating to possible objects in front of the motor vehicle; calculating for each template object a score relating to the match between said processed image and the template object; and identifying large scores of sufficient absolute magnitude of said calculated scores. The vision method further comprises the steps of applying an algorithm adapted to identify groups of said large scores, and assigning an identified group of large scores to a single match object.
