  • Patent number: 9866872
    Abstract: An encoder extracts motion vectors from a frame I(t?1) preceding the frame I(t) being encoded and processes them to create an estimated motion vector field I(t) for the frame being encoded. A minimized difference between the motion vector field of the frame being encoded and the estimated motion vector field is used to generate transform parameters, which are transmitted to the decoder as auxiliary information along with the usual motion prediction information. The decoder receives the transform parameters. The decoder also creates an estimated motion vector field I(t) for based on a preceding frame I(t?1) and applies the transform parameters to the estimated motion vector field to obtain missing motion vectors. The motion vector field rebuilt using the reconstructed missing motion vectors is used for subsequent error concealment/decoding/displaying.

    Abstract: An image forming apparatus includes a rotatable image drum for carrying a toner image; a transfer member contacted to the drum to transfer the toner image from the drum onto a transfer member; a cleaning blade provided downstream of the transfer member with respect to a peripheral moving direction of the drum and having a free end portion contacted to the drum, the blade being configured to remove, with rotation of the drum, toner remaining on the drum after transfer of the toner image by the transfer member; and a toner retaining member cooperative with the drum to provide a toner accommodation space toner removed from the drum by the blade. The toner retaining member can retain a part of the toner accommodated in the toner accommodation space and capable of being deformed by the toner accommodated in the accommodation space to discharge the toner from the accommodation space.
