Abstract
A video camera can be configured to highly compress video data in a visually lossless manner. The camera can be configured to transform blue and red image data in a manner that enhances the compressibility of the data. The data can then be compressed and stored in this form. This allows a user to reconstruct the red and blue data to obtain the original raw data for a modified version of the original raw data that is visually lossless when demosaiced. Additionally, the data can be processed in a manner in which the green image elements are demosaiced first and then the red and blue elements are reconstructed based on values of the demosaiced green image elements.
Claims43
A video camera comprising:
- a portable housing;
- a lens assembly supported by the housing and configured to focus light;
- a light sensitive device configured to convert the focused light into raw image data with a resolution of at least 2 k at a frame rate of at least about twenty-three frames per second;
- a memory device;
- and
- an image processing system configured to compress and store in the memory device the raw image data at a compression ratio of at least six to one and remain substantially visually lossless, and at a rate of at least about 23 frames per second.
A video camera comprising:
- a lens assembly supported by the housing and configured to focus light;
- a light sensitive device configured to convert the focused light into a raw signal of image data representing at least first, second, and third colors of the focused light;
- an image processing module configured to modify image data of at least one of the first and second colors based on the image data of the third color;
- a memory device;
- and
- a compression device configured to compress the image data of the first, second, and third colors and to store the compressed image data on the memory device at a frame rate of at least about 23 frames per second.
A video camera according to Cling 17, wherein the average of values comprises the average of values of image data of the third color from at least for sensor cells adjacent to the sensor cell of the first color.
A method of recording a motion video with a camera, the method comprising:
- guiding light onto a light sensitive device;
- converting the light received by the light sensitive device into raw digital image data at a rate of at least greater than twenty three frames per second;
- compressing the raw digital image data;
- and
- recording the raw image data at a rate of at least about 23 frames per second onto a storage device.
A method of processing an image, comprising:
- converting an image and into raw first image data representing a first color, raw second image data representing a second color, and raw third image data representing a third color;
- modifying at least the raw first image data and the raw second image data based on the raw third image data;
- compressing the raw third image data and the modified raw first and raw second image data;
- and
- storing the compressed data at a frame rate of at least about 23 frames per second.
A video camera comprising:
- a lens assembly supported by the housing and configured to focus light;
- a light sensitive device configured to convert the focused light into a signal of raw image data representing the focused light;
- a memory device;
- and
- means for compressing and recording the raw image data at a frame rate of at least about 23 frames per second.
A video camera comprising:
- a portable housing having at least one handle configured to allow a user to manipulate the orientation with respect to at least one degree of movement of the housing during a video recording operation of the camera;
- a lens assembly comprising at least one lens supported by the housing and configured to focus light at a plane disposed inside the housing;
- a light sensitive device configured to convert the focused light into raw image data with a horizontal resolution of at least 2 k and at a frame rate of at least about twenty three frames per second;
- a memory device configured to store video image data;
- an image processing system configured to compress and store in the memory device the raw image data at a compression ratio of at least six to one and remain substantially visually lossless, and at a rate of at least about 23 frames per second.
