International Classification:

H04N 5/92

US Classification:

386326

Abstract:

A method for storing a video on a storage device includes formatting each image in a plurality of images into a plurality of tiles, the plurality of images being captured as a temporal sequence of images at successive points in time; and generating a plurality of video segments from the temporal sequence of images by: selecting a tile from each image in the sequence of images to obtain a sequence of tiles to generate a video segment; selecting another tile from each image in the sequence of images to obtain another sequence of tiles to generate another video segment; and repeating the selecting a tile from each image in the sequence of images to obtain a plurality of sequences of tiles to generate the plurality of video segments. The method further includes storing the obtained plurality of video segments in a file on the storage device.

Abstract:

A method of configuring an image for data storage on a storage device in an overlapping-tiled format and a method of displaying a desired image selected for viewing on a display are disclosed. The method of configuring an image for data storage includes formatting an image to include a plurality of image tiles, each image tile in the plurality of image tiles having at least a portion that is substantially identical to at least a portion of an adjacent image tile in the plurality of image tiles. The method further includes converting data of the image from data in a first color space into data in a second color space so as to reduce a size of the data of the image, and storing the image data in the second color space.

International Classification:

G06K 9/62
G06K 9/00

US Classification:

382228, 382170

Abstract:

A system and method for determining statistical data within an image having pixels with relatively higher bit depth per band and a system and method of converting a first image within the image having pixels with the relatively higher bit depth per band into a second image having a relatively lower bit depth per band. The higher bit depth per band includes greater than 8 bits per band. The method of determining statistical data for pixels of an image includes dividing the image having pixels with the higher bit depth per band into a plurality of polygonal sections, each polygonal section including substantially homogenous features; computing statistical data for pixels within each polygonal section; and storing the statistical data with the image.

US Classification:

382173, 382224, 382282

Abstract:

A method of processing a viewport within large format imagery is described. In one embodiment, the method includes dividing the image into a matrix of a plurality of tiles, each tile in the plurality of tiles having a plurality of pixels; defining a viewport within the image, the viewport including one or more tiles in the plurality of tiles, the viewport having an origin point and a width and a height; and reading a strip of pixel data in each column of the matrix of tiles within the viewport starting at a column in the matrix of tiles containing the origin point. The strip of pixel data starts at a first line of the viewport and ends at the height of the viewport from the first line.

US Classification:

382205, 382173, 382305

Abstract:

A method of creating a container file for large format imagery and organizing data within the container file are described. In one embodiment, the method of creating the container file includes validating user input parameters for the file container, and determining whether the container file already exists, the container file having file container metadata. If the file container does not exist, creating the container by creating one or more empty records in a storage device, the one or more empty records having an image file section reserved for storing an image, an image metadata section reserved for storing data about the image and a record metadata section having at least a mark indicating that the image file section is empty. A size of the image file section, a size of the image metadata section and a size of the record metadata section are determined using the user input parameters.

PIXIA CORP. - Sterling VA

International Classification:

G09G 5/39

US Classification:

345531

Abstract:

A method of storing an image on a storage device in a tiled format is provided. The method includes formatting the storage device to include a block size such that a tile size is an integer multiple of the block size, and the tile size corresponds to a display output. The method further includes reading pixel data of a source image; and generating, from the read pixel data, a first tile and a second tile. The first tile and the second tile each have overlapping portions that overlap by an adjustable amount, and the overlapping portions include substantially identical pixel data. The method also includes storing the first tile and the second tile on the storage device; and repeating the reading, generating, and storing a plurality of times to store the image. The image is stored on the storage device as a contiguous string of data.
