    Abstract: A global image adjustment, such as dynamic range adjustment is established based on image characteristics. The image adjustment is based more heavily on pixel values in image areas identified as being important by one or more saliency mapping algorithms. In one application to dynamic range adjustment, a saliency map is applied to create a weighed histogram and a transformation is determined from the weighted histogram. Artifacts typical of local adjustment schemes may be avoided.

    Abstract translation: 基于图像特征建立全局图像调整,如动态范围调整。 图像调整更多地依赖于通过一个或多个显着性映射算法被识别为重要的图像区域中的像素值。 在一个应用于动态范围调整的应用中,应用显着图来创建称重直方图,并从加权直方图确定变换。 可以避免典型的局部调整方案的伪像。

    Abstract: Apparatus and methods for mapping video signal parameters such as tone and color may be applied at various points in a video generation and delivery pipeline. apparatus may be configured to control mappings based on a range of inputs which may include one or more of: ambient conditions, user inputs, control information, adaptation models. Apparatus and methods may be applied to display video or other images so as to preserve a creative intent embodied in video or other image data.
