Patent number: 11743438Abstract: A method for reducing a color shift of image pixels of an image for a motor vehicle captured by a camera, a computer program product and a control device for the vehicle are disclosed. For the respective image pixel of the image, the method involves determining a color information, which describes a color of the image pixel, checking whether the determined color information is larger than a minimum color information and smaller than a maximum color information, wherein the minimum and maximum color information delimit a color information range, in which reference image pixels describing a reference object sway. When the checking is successful, calculating a corrected color information in consideration of the determined color information and a correction factor and providing the calculated corrected color information instead of the determined color information, wherein the corrected color information in comparison to the determined color information has a reduced color shift.Type: GrantFiled: March 24, 2022Date of Patent: August 29, 2023Assignee: Connaught Electronics Ltd.Inventors: Mark Patrick Griffin, Brian Michael Thomas Deegan
