An image processing system performs intensity mapping in a manner that avoids color shifts and conserves processing resources while adapting image data for a target display device. The image processing system may convert input image data to a target color space in which brightness components are orthogonal to other color components. When intensity mapping is performed on image data, the intensity mapping operations do not induce the color shifts that were created in these other proposals. Resource conservation may be achieved by altering operation of perceptual quantization processes as used in other intensity mapping systems. Where prior proposals performed perceptual quantization on all color components of the image data being processed, the disclosed embodiments perform perceptual quantization on only a brightness color component of image data. Thus, these embodiments avoid resource expenditures that otherwise would be spent on perceptual quantization of two other color components.

Mapping image/video content to target display devices with variable brightness levels and/or viewing conditions

Systems and methods for identifying and presenting information regarding a fitness cycle using earphones with biometric sensors are provided. Fatigue level associated with fatigue experienced in response to a stimulus and recovery from such fatigue may be determined based on heart rate variability (HRV) data and learned user characteristics. One or more cycles of fatigue and recovery can be identified as a fitness cycle(s), each fitness cycle encompassing a period of time beginning with the stimulus associated with the fitness-related activity and progressing through recovery from the fatigue experienced in response to the stimulus associated with the fitness-related activity. Information regarding the fitness cycle(s) can be presented to a user in a variety of ways, including on a display of a computing device in communication with the earphones with biometric sensors.

A display system including a sub-pixel formatted display (330) is disclosed. A source (310) generates image data, converts the image data into sub-pixel formatted data having a first sub-pixel colour order (RGBG), transmits the sub-pixel formatted data to a display device (320) including the display (330). The display device (320) converts the sub-pixel formatted data into sub-pixel formatted data having a second sub-pixel colour order, and applies the sub-pixel data with the second sub-pixel colour order to the display (320).

Method and apparatus for a sink device to receive and process sub-sampled pixel data

Systems and methods for efficient lossless compression of captured raw image information are presented. A method can comprise: receiving raw image data from an image capture device, segregating the pixel data into a base layer portion and an enhanced layer portion, reconfiguring the base layer portion expressed in the first color space values from a raw capture format into a pseudo second color space compression mechanism compatible format, and compressing the reconfigured base layer portion of first color space values. The raw image data can include pixel data are expressed in first color space values. The segregation can be based upon various factors, including a compression benefits analysis of a boundary location between the base layer portion and enhanced layer portion. The reconfiguring the base layer portion can include separating the base layer portion based upon multiple components within the raw data; and forming base layer video frames from the multiple components.
