Document Type and Number:
WIPO Patent Application WO/2022/207582
Kind Code:
A1
Abstract:
The invention provides a method for managing image data in an automotive lighting device (10). This method comprises the steps of providing an image pattern (1), dividing the image pattern (1) in rows or columns of pixels (2), calculating a first gradient value related to the relation between the numeric value of a first pixel and the numeric value of an adjacent pixel, checking, for each pixel, if the difference between the corresponding gradient value and the first gradient fulfils one of a first or second condition, define linear segments, compress the data of the linear segments and send the compressed data to the light module. The invention also provides an automotive lighting device (10) for performing the steps of such a method.
