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。
