  • Patent number: 9666164
    Abstract: An image processing apparatus includes: a pattern identification unit configured to perform pattern identification for first image data; a first data conversion unit configured to perform first data conversion for the first image data, after a pattern of the first image data is identified, to generate second image data; a second data conversion unit configured to perform second data conversion for the second image data to generate third image data; and a process selection unit configured to determine whether or not to perform at least one of the pattern identification, the first data conversion, or the second data conversion according to a measured value that is input from an outside or an on/off state of a call mode.
    Type: Grant

  • Publication number: 20150022539
    Abstract: An image processing apparatus including a display unit including pixels and more than one core processor. Each core processor includes: a diffusion module changing first pixel data of an image signal divided according to rows and then outputting it using a threshold value corresponding to the first pixel data, generating diffusion data using a difference between the changed first pixel data and the first pixel data, and changing second pixel data and third pixel data using the diffusion data; a memory storing an image signal including the image signal divided according to rows and then outputting it and the pixel data changed in the diffusion module; and a memory controller reading an image signal including pixel data changed in the diffusion module and displaying the read image signal to the display unit.
