  • Patent number: 9218119
    Abstract: A computer device with a sensor subsystem for detecting off-surface objects, that carries out continued processing of the position and shape of objects detected in the vicinity of the device, associates these positions and shapes with predetermined gesture states, determines if the object is transitioning between gesture states and provides feedback based on the determined transition between the gesture states.

  • Patent number: 8396306
    Abstract: An image representation format for representing a digital image comprises: image information stored as a bitstream representing sequential image blocks, each block comprising one or more components, each component comprising one or more data units and each data unit being represented as a Huffman-coded stream of coefficients of basis functions, wherein a zeroth order coefficient is represented as a difference to the previous zeroth order coefficient of the corresponding component, and a block information table, which comprises: indicators to the first coefficient of a specified order of each image block in said bitstream, information indicating the number of bits in the bitstream between adjacent coefficients of said specified order of the image block, and the zeroth order coefficient of at least the first data unit of each component, said zeroth order coefficient being represented in a non-differential form.

  • Patent number: 8081194
    Abstract: The invention relates to a method for enhancing color resolution and particularly for obtaining bit resolution in a display using a bits per pixel system frame buffer. The invention uses logic to create intermediate pixel values between bpp color values. The invention proposes to store the image in the system frame buffer always with a fixed number of bits and using Error Diffusion Dither. Then a postprocessing filter is provided to provide the enhanced color resolution using a greater number of bits per pixel as accepted by the display means. The invention also relates to a device exploiting the method.

  • Patent number: 7831101
    Abstract: The invention relates to a method for determining where a next data unit of a bit stream of an image starts. The method comprises analyzing a first part of a bit stream entry, the bit stream entry being included in a data unit, determining from said analysis of the first part of the bit stream entry the number of bits used by the bit stream entry, skipping the number of bits determined to be used by the bit stream entry, and determining if an end of block symbol has been reached, if an end of block symbol has not been reached then a new bit stream entry starting at the end of the previous is analyzed.
