摘要： A video camera comprising: a portable housing; a lens assembly supported by the housing and configured to receive light; a light sensitive device configured to convert the light into digital raw image data with a resolution of at least 2k at a frame rate of at least about 23 frames per second; a memory device supported by the housing; and an image processing system configured to perform a pre-emphasis function on the digital raw image data, to compress the digital raw image data after performing the pre-emphasis function such that the digital raw image data remains substantially visually lossless upon decompression, and to store the compressed digital raw image data in the memory device at a rate of at least about 23 frames per second, wherein the pre-emphasis function comprises a curve defined by the function y=(x+c)^g, where 0.01

摘要翻译： 摄像机可以配置为以视觉上无损的方式高度压缩视频数据。 可以将相机配置为以增强数据可压缩性的方式转换蓝色和红色图像数据。 数据然后可以压缩并以这种形式存储。 这允许用户重建红色和蓝色数据以获得原始原始数据的修改版本的原始数据，该数据在去马赛克时视觉上无损。 此外，可以以绿色图像元素首先被去马赛克然后基于去马赛克绿色图像元素的值重建红色和蓝色元素的方式来处理数据。

摘要： Embodiments provide a video camera that can be configured to allow tagging of recorded video and/or capture of video segments or sequences of images in response to user actuation of a camera control identifying an event of interest. For example, a user may press a button on the camera when an event of interest occurs, and in response the camera may tag a captured video file at a timestamp corresponding to the event. In another example, the user may initiate capture of video segments or sequences of images at an occurrence of an event of interest by pressing a button. The camera may include an image data buffer that may enable capture of video segments and/or sequences of images occurring before the user initiates capture of the event. User interfaces may enable the user to quickly review the captured video or sequences of images of the events of interest.

摘要： In one embodiment, a camera includes an image sensor within a camera housing that converts light entering the camera housing through an optical filter into digital image data. The optical filter can have a variable opacity. A processor in communication with the image sensor identifies operation settings for the optical filter and adjusts an opacity level of the optical filter over an exposure period in accordance with the operation settings for the optical filter. In addition, the processor modifies values of the digital image data based at least on the operation settings for the optical filter.

摘要： The disclosure herein relates to devices for compression, decompression or reconstruction of image data for still or moving pictures, such as image data detected with a digital camera. In some embodiments, data channels are compressed using a scalable compression algorithm. The compression algorithm may allow customization of compression parameters, such as a quantization factor, code block size, number of transform levels, reversible or irreversible compression, a desired compression ratio with a variable bit rate output, a desired fixed bit rate output with a variable compression rate, progression order, output format, or visual weighting. A lower quality image or an image with lower resolution may be reconstructed using only some of the compressed data. Use of offsets to various layers and color channels allow reconstruction of the image without requiring decompression of all of the full image data.
