  • Image processing apparatus and image processing method
    Patent number: 9734563
    Abstract: An image is sharpened by using a frequency component exceeding a Nyquist frequency. In particular, an image processing apparatus 100 of the disclosure herein for generating an output image by sharpening an input image includes a first nonlinear processing unit 101 configured to generate a first signal by carrying out nonlinear processing on an input image signal representing the input image, a sharpening processing block 102 configured to generate a second signal containing a frequency component higher than a frequency component contained in the first signal by carrying out sharpening processing on the first signal, and an adder 103 configured to generate an output image signal representing the output image by adding the second signal to the input image signal.
    Type: Grant
    Filed: August 29, 2014
    Date of Patent: August 15, 2017
    Assignee: KEISOKU GIKEN CO., LTD.
    Inventors: Seiichi Gohshi, Jin Ogasawara, Shinichiro Nakamura, Keisuke Ohashi
