Title:
IMAGE PROCESSING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/190342
Kind Code:
A8
Abstract:
The invention relates to an image processing apparatus for determining on the basis of an image defining a plurality of pixel values of an array of pixels (10a-d) an interpolated pixel value of a target pixel (12a-c). The image processing apparatus comprises processing circuitry configured to: obtain a direction angle value associated with the target pixel (12a- c); select for the target pixel (12a-c) a plurality of primary interpolation support pixels (10a- d) from the array of pixels (10a-d) on the basis of the position of the target pixel (12a-c); determine pixel values of a first and a second secondary interpolation support pixel (11ac, 11bd) on the basis of the pixel values of the selected primary interpolation support pixels (10a-d), the direction angle value (a, b) and the position of the target pixel (12a-c); and determine the interpolated pixel value of the target pixel (12a-c) on the basis of the pixel values of the first and second secondary interpolation support pixel (11ac, 11bd) and the position of the target pixel (12a-c). The technique offers a variety of advantages.
