Patent ID: 7460718

Claim:
A conversion device for performing a raster scan conversion between a JPEG decoder and an image memory, the bandwidth of the image memory being greater than one byte, the conversion device comprising: an input for receiving data corresponding to an image to be displayed, said received data being in a JPEG decoder output data format; and a processor for reconstructing and writing the image to be displayed into the image memory, in a display module expected input data format, the processor comprising an intermediate memory, a first logic stage for writing the received data byte by byte into the intermediate memory at chosen addresses such that the written data form a sequence of data in the display module expected input data format, and a second logic stage for reading the written data in the intermediate memory, forming successive packets of read data having a size corresponding to the bandwidth, and successively writing the packets into the image memory at chosen addresses such that the written packets together form all the lines of the image.
