Title:
RESOLUTION CONVERSION METHOD AND DEVICE, AND ULTRA-HIGH DEFINITION TELEVISION
Document Type and Number:
WIPO Patent Application WO/2014/139289
Kind Code:
A1
Abstract:
Provided are a resolution conversion method and device, and an ultra-high definition television. The resolution conversion method comprises the following steps: acquiring a diagonal interpolation parameter matrix in a vertical direction and a diagonal interpolation parameter matrix in a horizontal direction; and according to the diagonal interpolation parameter matrix in the vertical direction and the diagonal interpolation parameter matrix in the horizontal direction, performing diagonal interpolation processing on an input signal of which the resolution is to be converted so as to acquire a target resolution signal. By performing diagonal interpolation processing on an input signal of which the resolution is to be converted so as to acquire a target resolution signal according to the diagonal interpolation parameter matrix in the vertical direction and the diagonal interpolation parameter matrix in the horizontal direction, on the one hand, the image distortion can be effectively reduced, and on the other hand, blurred images and jagged images can be effectively prevented from occurring, thereby achieving the purpose of improving the image definition and picture quality.
