摘要： According to various embodiments of the invention, a system and method are provided for enabling interaction with, manipulation of, and control of depth-assigned content in depth-enhanced pictures. Depth-assigned content can be assigned to a specified depth value. When a depth-enhanced picture is refocused at a focus depth substantially different from the specified assigned depth value, the depth-assigned content may be omitted, grayed out, blurred, or otherwise visually distinguished. In this manner, content associated with an in-focus image element can be visually distinguished from content associated with an out-of-focus image element. For example, in at least one embodiment, depth-assigned content is visible only when an image element associated with the content is in focus (or nearly in focus). According to various embodiments of the invention, many different types of interactions are facilitated among depth-assigned content, depth-enhanced pictures, and other content.

摘要： Described is a stereoscopic display (telepresence) system that includes a depth cue adjustment mechanism for changing screen disparity to move a fixation distance of a viewer (subject) closer to a focus distance, thereby providing more desirable viewing conditions. In one aspect, the depth cue adjustment mechanism adjusts a depth cue by moving the fixation distance forward, and/or by moving the focus distance backward. Also described is detecting encroachment, where the object is perceived as being too close to the subject viewer for comfort, and adjusting one or more depth cues (e.g., object scale) to counteract the sensation of the encroachment.

摘要： A system and method for managing multiple frame buffers. The system includes multiple frame buffers, and thus reduces the risk of dropped frames. The system controls and bounds render-to-display latency, and provides an application friendly and effective interface to the frame buffers. The system operates by estimating a latency of a frame that is yet to be rendered. The system determines whether the latency is greater than a target latency. If the latency is greater than the target latency, then the system blocks the application that is responsible for rendering the frame before rendering of the frame commences. As a result, render-to-display latency is bounded to the target latency. The system addresses the naming issue by providing the application with access to only the front buffer and the back buffer. In particular, the present system maintains a queue of one or more frame buffers. The newest frame buffer appended to the queue is considered to be the front buffer. The oldest frame buffer in the queue is displayed. A frame buffer not in the queue is considered to be the back buffer. Rendering is enabled to the back buffer. Once rendering to the back buffer is complete, the back buffer is appended to the queue and becomes the new front buffer.
摘要翻译： 一种用于管理多个帧缓冲器的系统和方法。 该系统包括多个帧缓冲区，从而降低丢帧的风险。 系统控制和限制渲染到显示的延迟，并为帧缓冲区提供了一个应用程序友好和有效的接口。 该系统通过估计尚未呈现的帧的等待时间来进行操作。 系统确定延迟是否大于目标延迟。 如果延迟大于目标延迟，则系统在渲染帧开始之前阻止负责渲染帧的应用程序。 因此，渲染到显示的延迟与目标延迟有关。 该系统通过提供应用程序只访问前端缓冲区和后台缓冲区来解决命名问题。 特别地，本系统保持一个或多个帧缓冲器的队列。 附加到队列中的最新帧缓冲区被认为是前缓冲区。 显示队列中最早的帧缓冲区。 不在队列中的帧缓冲区被认为是后台缓冲区。 向后缓冲区启用渲染。 一旦渲染到后台缓冲区就完成了，后台缓冲区被追加到队列中，并成为新的前端缓冲区。

摘要： According to various embodiments, multiple frames, each having image data and metadata, can be aggregated into pictures. The frames may come from different image capture devices, enabling aggregation of image data from multiple sources. Aggregation can be automatic, or it can be performed in response to user input specifying particular combinations of frames to be aggregated. In various embodiments, pictures are mutable, whereas immutability of the constituent frames is enforced. In various embodiments, certain metadata elements that are not essential to rendering can be selectively removed from frames, so as to address privacy concerns. In various embodiments, frames can be authenticated by the use of digests generated by a hash function.

摘要： According to various embodiments of the invention, improved downsampling techniques are employed, which can be applied to light field images and which preserve the ability to refocus (and otherwise manipulate) such images. Groups of pixels, rather than individual pixels, are downsampled; such groups of pixels can be defined, for example, as disks of pixels. Such downsampling is accomplished, for example, by aggregating values for pixels having similar relative positions within adjacent disks (or other defined regions or pixel groups) of the image. When applied to light field images, the downsampling techniques of the present invention reduce spatial resolution without sacrificing angular resolution. This ensures that the refocusing capability of the resulting light field image is not reduced and/or adversely impacted.
摘要翻译： 根据本发明的各种实施例，采用改进的下采样技术，其可以应用于光场图像并且保留重新聚焦（或以其他方式操纵）这种图像的能力。 像素组而不是单个像素被下采样; 这样的像素组可以被定义为例如像素的像素。 这样的下采样是通过例如聚集在图像的邻近盘（或其他定义的区域或像素组）内具有相似相对位置的像素的值来实现的。 当应用于光场图像时，本发明的下采样技术降低空间分辨率而不牺牲角分辨率。 这确保所得到的光场图像的重新聚焦能力不会降低和/或不利影响。
