摘要： In an image sequence stabilization method and a camera, a sequence of input digital images are captured. The sequence of input digital images is replicated to provide a corresponding sequence of archival images and a corresponding sequence of display images. The archival image sequence is automatically stabilized to provide a stabilized archival image sequence. The display image sequence is automatically stabilized to provide a stabilized display image sequence. The stabilization methods used for the two sequences are different, although both can be digital.

摘要： A method is described for processing motion picture scene data through a process in which the scene data is initially acquired from a film or an electronic camera and ultimately projected onto a screen, wherein image losses potentially occur during distribution and projection stages of the process. The method includes the steps of: (a) representing the scene data in a non-linear space; and (b) compensating for the image losses associated with the distribution and projection stages at a point in the process before they occur by converting the scene data into an intermediate space representing the space in which the losses occur and filtering the scene data in the intermediate space to compensate the scene data for the losses. Additional steps provide additional benefits, including the steps of: (a) digitally scaling the digital scene data anamorphically to provide an image that makes full use of the available film space on the film; (b) recording multiple intermediate prints from the digital scene data and performing a single printing step to make each release print from an intermediate print; and (c) using motion compensated frame averaging to digitally remove noise.
摘要翻译：描述了一种用于通过其中首先从胶片或电子照相机获取场景数据并且最终投影到屏幕上的过程来处理运动图像场景数据的方法，其中在处理的分布和投影阶段可能会出现图像损失。该方法包括以下步骤：（a）在非线性空间中表示场景数据; 和（b）通过将场景数据转换成表示损失发生的空间的中间空间并且对中间物体中的场景数据进行滤波来补偿在它们发生之前在过程中的点处与分布和投影阶段相关联的图像损失空间补偿场景数据的损失。附加步骤提供额外的好处，包括以下步骤：（a）以变形方式数字缩放数字场景数据，以提供充分利用电影上可用胶卷空间的图像; （b）从数字场景数据记录多个中间印刷品，并执行单个印刷步骤，以从中间印刷品制作每个印张; 和（c）使用运动补偿帧平均来数字地去除噪声。
