Abstract: The application relates to a method for reducing visual artefacts in a frame of a digital video signal, which is coded by blocks and then decoded. A block type is defined according to the coding method for a block selected according to a predetermined set of coding types. In the method filtering is performed to reduce visual artefacts due to a block boundary. The filtering performed depends on block types of the frame in the environment of the block boundary.

Abstract: An apparatus includes a three dimensional array of light receptors disposed within a substrate having a light receiving surface, where light receptors disposed closer to the light receiving surface are responsive to light having shorter wavelengths than light receptors disposed further from the light receiving surface, and where each light receptor is configured to output a binary value and to change state between an off-state and an on-state by the absorption of at least one photon.
