1. A method of operating a motion video imaging device capable of generating mosaiced image data at a frame rate of at least about 23 frames per second, pre-emphasizing the mosaiced image data, transforming the mosaiced image data, and compressing the pre-emphasized, transformed mosaiced image data, the method comprising:

  • with an image sensor, generating mosaiced image data at a frame rate of at least about 23 frames per second for a plurality of motion video image frames from light entering a body of a motion video imaging device,wherein the mosaiced image data has a resolution per frame of at least 4 k and comprises;

    first pixel data corresponding to first pixels of the image sensor and that represents light having a green color, andsecond pixel data corresponding to second pixels of the image senor and that represents light having a red color or a blue color;

    pre-emphasizing the mosaiced image data;

    for each second pixel of a plurality of the second pixels, transforming the mosaiced image data at least by;

    calculating an average of values of the first pixel data corresponding to four of the first pixels that are adjacent to the second pixel, andsubtracting the calculated average from a value of the second pixel data corresponding to the second pixel;

    subsequent to said transforming and said pre-emphasizing, compressing the pre-emphasized, transformed mosaiced image data with a mathematically lossy wavelet compression to generate compressed mosaiced image data, the compressed mosaiced image data being able to be decompressed and demosaiced as part of an image processing to generate video output having a resolution per frame of at least 4 k; and

    outputting the compressed mosaiced image data for storage at a frame rate of at least 23 frames per second.
