摘要： A video system includes an analyzer and a bit depth predictor. The analyzer receives a first coded video signal, which is indicative of first values for pixels. The first values are associated with a first bit depth. The analyzer, for each pixel, analyzes the first values for the pixels located in a neighborhood that contains said each pixel. The bit depth predictor, based at least in part on the analysis, generates a second coded video signal that is indicative of second values for the pixels. The second values are associated with a second bit depth that is different than the first bit depth.

摘要： Techniques are disclosed involving contrast adjustment for images. For example, an input image is classified based on its pixel value characteristics, as expressed in an input brightness histogram. From such a classification, a target histogram distribution for a corresponding output image (i.e., a contrast-adjusted transformation of the input image) may be specified. With the target histogram of the output image specified, a transformation function may be derived that maps input image values to output image values. Moreover, transitions of such transformation functions may be smoothed. Such smoothing may provide advantages, such as a reduction in flickering associated with video data.
摘要翻译：公开了涉及图像的对比度调整的技术。例如，输入图像根据输入亮度直方图所表示的像素值特性进行分类。根据这样的分类，可以规定对应的输出图像的目标直方图分布（即输入图像的对比度调整变换）。利用指定的输出图像的目标直方图，可以导出将输入图像值映射到输出图像值的变换函数。此外，这种变换函数的转换可以被平滑化。这种平滑可以提供诸如减少与视频数据相关联的闪烁的优点。
