  • Patent number: 9319602
    Abstract: A method of processing an image includes: offsetting aliasing by analyzing frequency characteristics of at least one color channel and a NIR channel, of a MSFA pattern image; generating a high resolution base image; and offsetting an artifact from the high resolution base image by weighting the high resolution base image and a blur image, based on a pixel difference value between the blur image and the high resolution base image.
    Type: Grant
    Filed: June 17, 2013
    Date of Patent: April 19, 2016
    Assignees: INDUSTRY-ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITY, Hanwha Techwin Co., Ltd.
    Inventors: Jeong-Ahn Lee, Min-seok Lee, Ji-yong Kwon, Moon-gi Kang
  • Patent number: 8938121
    Abstract: An image processing apparatus includes an adaptive interpolation device which converts a MFA pattern image into a quincuncial pattern image based on difference values, and interpolates color channels and an NIR channel, based on difference values of the converted quincuncial pattern image in vertical and horizontal pixel directions; a frequency compensation device which obtains a high-resolution MFA image using high-frequency and medium-frequency components of a high-resolution base image, based on linear regression analysis and compared energy levels of MFA channel images to an energy level of a base image; and a channel interference suppression device which removes color distortion generated between each channel of the high-resolution MFA image, and another channel of the high-resolution MFA image and a base channel using a weighted average of pixel value differences between each channel of the high-resolution MFA image, and the other channel of the high-resolution MFA image and the base channel.
