    Abstract: The invention is a method for scanning an image data file to determine the presence of a payload, including the steps of identifying the values of one or more lower-order bits in the bytes of an uncompressed image data file to determine the distribution of values at one or more bit positions, and comparing bit position images to reveal hidden payloads from significant variations in contiguous color blocks in the bit position images not otherwise explainable from the original image.

    Abstract: A method for previewing a color graded image commences by first obtaining color metadata corresponding to a sample image appearance selected by a user from among a set of different sample image appearances, each sample image appearance having associated color metadata. The color metadata corresponding to the selected sample image appearance is stored with an image file the user has selected for color grading. The color metadata corresponding to the selected sample image appearance is applied to the image file to generate a preview of the image file, as it would appear when color graded with the color metadata.

    Abstract translation: 通过首先从一组不同的样本图像外观中选出的与用户选择的样本图像外观相对应的颜色元数据,从而开始预览分色图像的方法,每个样本图像外观具有相关联的颜色元数据。 与所选择的样本图像外观相对应的颜色元数据与用户已经选择用于颜色分级的图像文件一起存储。 与所选择的样本图像外观相对应的颜色元数据被应用于图像文件,以生成图像文件的预览,就像使用颜色元数据进行颜色分级时一样。

    Abstract: To allow a better coordination between an image creation artist such as a movie director of photography and the final viewer (via the display and its built-in image processing), we describe method of adding image defining information to an input image signal (I), comprising: - showing the input image (I) to a human operator; receiving via a user interface (303, 308) descriptive data (D) from the human operator, the descriptive data (D) including at least luminance values and/or geometrical shape information on the one hand, and a regime descriptor (rd) on the other hand; encoding into an output description data signal (DDO), relatable to an output image signal (O) based upon the input image signal (I), of the descriptive data (D) in a technical format standardized to be intended for use by a receiving display to control its image processing for changing the color properties of its rendered images.

    Abstract: Techniques relating to spectral color management are described. In one example, a process receives spectral color data associated with a physical color response. In this example the process also processes the spectral color data into device data suitable for a target device while maintaining an ability to replicate the physical color response from the device data.
