Abstract
This disclosure provides methods, devices, and systems for color volume mapping (CVM) techniques that operate in the Jabcolor space. In some aspects, an image processor may receive image data having color channels associated with a color space that is not perceptually uniform and may convert the image data to the Jabcolor space. The image processor may perform a global CVM operation which maps a range of J, a, and bvalues supported by the image source to a range of j, a, and bvalues supported by the image target. The image processor may further perform a local CVM operation which adaptively tunes the J, a, and bchannels of image data based on various properties of the received image. Still further, the image processor may adaptively blend Jvalues at the edges of objects and other features to preserve details in low-contrast regions of the received image.
