Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. An image processing apparatus comprising: an adaptive interpolation device configured to convert a multispectral filter array (MFA) pattern image into a quincuncial pattern image based on difference values in a diagonal pixel direction, and interpolate color channels and a near infrared (NIR) channel of the MFA pattern image to a maximum resolution, based on difference values of the converted quincuncial pattern image in vertical pixel directions and horizon…
