Method and device for transmitting/receiving image data at high speed

摘要

Provided are a method of transmitting and receiving image data with high speed, which includes sequentially transmitting image data output from an image sensor through one or more transmission channels with a speed corresponding to a bandwidth of the transmission channels, and sequentially recording image data received through one or more transmission channels in a frame store with a speed corresponding to a total bandwidth obtained by summing bandwidths of the respective one or more transmission channels, and an apparatus for implementing the method.

1. An apparatus for transmitting image data with high speed, comprising:
a pixel buffer configured to include several line memories connected to one or more output taps of an image sensor and temporarily store image data; one or more line buffers (LBs); a buffer recording controller configured to sequentially record image data output from the pixel buffer in the one or more LBs; and a transmission controller configured to sequentially read the image data stored in one line buffer among the one or more LBs while the buffer recording controller writes another line buffer among one or more LBs, and control the image data to be sequentially output to one or more transmission channels with a recording speed corresponding to a bandwidth of the transmission channels, wherein the LBs are multiport memories having a plurality of write ports, the buffer recording controller is plural in number to correspond to the write ports, one or more output taps of the image sensor are divided into a plurality of groups, and the groups are allocated to the plurality of buffer recording controllers, respectively, and the plurality of buffer recording controllers record the image data output from the allocated groups of output taps in the corresponding write ports, respectively.
