Document Type and Number:
WIPO Patent Application WO/2017/004953
Kind Code:
A1
Abstract:
Disclosed in an embodiment of the invention are a numerical image conversion method and device. The method comprises: acquiring a RGB indication signal of a relevant forward pixel; comparing a RGB signal of a current pixel with the RGB indication signal of the relevant forward pixel; if the RGB signal of the current pixel is identical to the RGB indication signal of the relevant forward pixel, acquiring and assigning a YUV indication signal of the relevant forward pixel to a YUV signal of the current pixel; and if the RGB signal of the current pixel is different from the RGB indication signal of the relevant forward pixel, re-computing the YUV signal of the current pixel according to the RGB signal thereof. The numerical image conversion method and device disclosed in the embodiment of the invention can effectively reduce a computation load for image data conversion.
