  • Image processor capable of edge enhancement in saturated region
    Patent number: 7110004
    Abstract: An image processing device includes a data zone expansion circuit and an image processing circuit. The data zone expansion circuit receives input data, increases a number of data bits of the input data, and provides data with the increased number of data bits. The image processing circuit performs image processing on the data with the increased number of data bits.
    Type: Grant

  • Image processor capable of edge enhancement in saturated region
    Publication number: 20010013872
    Abstract: A display device comprises a data zone expansion circuit 16R expanding a data zone of signal R and a data zone contraction circuit 18R contracting a data zone are provided at the proceeding and succeeding stages of an image processing circuit 20R performing an edge enhancement processing. The circuit 16R performs bit shift of the input signal R to the higher bit side and adds an offset value &bgr; to the bit-shifted signal, and the circuit 18R performs the inversion of this linear conversion.
