摘要： A hardware implementation of a digitized image corrector converts a colorimetric representation of an original image into a new representation based upon the colors of the original and target images, as well as user supplied artistic parameters. The digitized image corrector receives digitized Red, Green and Blue input signals that comprise a colorimetric representation of an original film scene, and generates digitized Red, Green, and Blue output signals according to the specifications of SMPTE 240 M. The digitized image corrector is comprised of four identical hardware correction modules, which are coupled to receive correction parameters from an external source. Each module has a bypass switch for entering a bypass mode, which is used for reconfiguration of the module's correction parameters without affecting the output image. Each correction module receives digitized input signals and generates digitized output signals by transforming the digitized input signals according to a set of predetermined correction parameters and a transfer function defined by a matrix of functions.
摘要翻译： 数字化图像校正器的硬件实现将原始图像的色度表示转换为基于原始和目标图像的颜色以及用户提供的艺术参数的新表示。 数字化图像校正器接收包括原始电影场景的比色表示的数字化的红色，绿色和蓝色输入信号，并且根据SMPTE 240M的规格生成数字化的红色，绿色和蓝色输出信号。数字化图像校正器包括 的四个相同的硬件校正模块，它们被耦合以接收来自外部源的校正参数。 每个模块都有一个用于进入旁路模式的旁路开关，用于在不影响输出图像的情况下重新配置模块的校正参数。 每个校正模块接收数字化的输入信号，并通过根据一组预定的校正参数和由功能矩阵定义的传递函数对数字化的输入信号进行变换来产生数字化的输出信号。
