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。

摘要： A 3D stereo image of a scene is generated by generating first image data of the scene using light field data representing light rays from a first direction, and second image data of the scene using light field data representing light rays from a second direction. The 3D stereo image of the scene is then generated using the first image data and the second image data. A microlens array may be used to direct light rays onto a photosensor array, wherein each microlens of the microlens array includes a physical aperture which correlates to a plurality of associated photosensors, a first virtual aperture which correlates to a first subset of the associated photosensors, and a second virtual aperture which correlates to a second subset of the associated photosensors. Each virtual aperture thus provides light rays from a different direction for use in generating the 3D stereo image.

摘要： A light field data acquisition device includes optics and a light field sensor to acquire light field image data of a scene. In at least one embodiment, the light field sensor is located at a substantially fixed, predetermined distance relative to the focal point of the optics.

摘要： Digital images are computed using an approach for correcting lens aberration. According to an example embodiment of the present invention, a digital imaging arrangement implements microlenses to direct light to photosensors that detect the light and generate data corresponding to the detected light. The generated data is used to compute an output image, where each output image pixel value corresponds to a selective weighting and summation of a subset of the detected photosensor values. The weighting is a function of characteristics of the imaging arrangement. In some applications, the weighting reduces the contribution of data from photosensors that contribute higher amounts of optical aberration to the corresponding output image pixel.

摘要： A light field data acquisition device includes optics and a sensor to acquire light field image data of a scene. In at least one embodiment, the sensor is located at a substantially fixed, predetermined location relative to the focal point of the optics. The device determines a first virtual focus depth different from an optical focus depth of the light field image data, and automatically generates and outputs data representative of a first image of the scene at the first virtual focus depth. In response to user input, the device determines a second virtual focus depth and generates data representative of a second image of the scene at the second virtual focus depth.

摘要： Various approaches to imaging involve selecting directional and spatial resolution. According to an example embodiment, images are computed using an imaging arrangement to facilitate selective directional and spatial aspects of the detection and processing of light data. Light passed through a main lens is directed to photosensors via a plurality of microlenses. The separation between the microlenses and photosensors is set to facilitate directional and/or spatial resolution in recorded light data, and facilitating refocusing power and/or image resolution in images computed from the recorded light data. In one implementation, the separation is varied between zero and one focal length of the microlenses to respectively facilitate spatial and directional resolution (with increasing directional resolution, hence refocusing power, as the separation approaches one focal length).
