CPC Class H04N

Methods for mapping an image from one dynamic range to another dynamic range are presented. The mapping is based on a sigmoid-like function determined by three anchor points. The first anchor point is determined using the black point levels of a reference and a target display, the second anchor point is determined using the white point levels of the reference and target displays, and the third anchor point is determined using mid-tones information data for the input image and the mid-tones level of the target display. The mid-tones level of the target display is computed adaptively based on a desired range of constant brightness and a mapping function. The mapping function mapping may be piece-wise linear (in the log domain), piece-wise continuous, or a sigmoid. Examples for mapping high dynamic range images to standard dynamic range displays are presented.

Method and apparatus are disclosed for stabilizing in-vehicle projected reality. An example in-vehicle projected reality system includes headset for displaying a projected reality image. The system also includes a localizer device for determining a headset pose in the vehicle. The system also includes a computing device for receiving the headset pose, receiving vehicle inertial data, determining a stabilized image based on the received headset pose and vehicle inertial data, and providing the stabilized image to the headset.

Methods and apparatus to perform audio watermarking and watermark detection and extraction are disclosed. Example apparatus disclosed herein to embed a code into an audio signal include means for selecting frequency components to be used to represent the code, different sets of frequency components to represent respectively different information, respective ones of the frequency components in the sets of frequency components located in respective code bands, there being multiple code bands and spacing between adjacent code bands being equal to or less than the spacing between adjacent frequency components in the code bands. Disclosed example apparatus further include means for synthesizing the frequency components to be used to represent the code and means for combining the synthesized frequency components with an audio block of the audio signal.

An assistive listening system that comprises an auditory interpretation device with a digital receiver that is tuned to receive a particular digital signal from a digital audio transmitter with microphone and a digital display screen to view human voice audio interpreted as text.

A system and method for determining video clips including interesting content from video data. The system may receive annotation data identifying time and positions corresponding to objects represented in the video data and the system may determine priority metrics associated with each of the objects. By associating the priority metrics with the time and positions corresponding to the objects, the system may generate a priority metric map indicating a time and position of interesting moments in the video data. The system may generate moments and/or video clips based on the priority metric map. The system may determine a time (e.g., video frames) and/or space (e.g., pixel coordinates) associated with the moments/video clips and may simulate camera motion such as panning and/or zooming with the moments/video clips. The system may generate a Master Clip Table including the moments, video clips and/or annotation data associated with the moments/video clips.
