  • Patent number: 8754955
    Abstract: An interface circuit for an image receiving apparatus is disclosed. The interface circuit includes a plurality of signal transporting units, and each of the signal transporting units has a first signal receiving terminal and a second signal receiving terminal for receiving a first input signal and a second input signal respectively. Each of the signal transporting units compares the first input signal and the second input signal to generate a compare result. Each of the signal transporting units outputs the first input signal and the second input signal and/or the compare result according to a setting mode.

  • Patent number: 8515189
    Abstract: An electronic device includes a multi-field sensor, a memory, and a codec wrapper module, in which the codec wrapper module includes at least one encoder and at least one decoder. The encoder compresses raw data of an image into an image bit stream with a compression ratio through the following steps. The image is segmented into various image bands. Storage space is allocated in the memory and is segmented into various compressed band regions according to the compression ratio and a bit stream length of the raw data. A starting position of each compressed band region is recorded as a current ending position. Lines, sequentially received, are compressed into compressed bit streams respectively. The compressed bit streams are sequentially written into the corresponding compressed band regions according to field indexes of the lines, an output field order, and a group formed by the image bands corresponding to the lines.
