CONTROLLER FOR VARIABLE LIGHT DISTRIBUTION LAMP

原文（中国語）

The controller generates a control image for controlling a variable light distribution lamp. The controller acquires shading information that indicates a shading zone which is a region to be shaded. Among a plurality of first pixels contained in the control image, a pixel value of a part that corresponds to the shading zone is zero. When the controller gradually changes the pixel value of the first pixels contained in the control image from zero towards a target value, the rate of increase of the pixel value in the first period that follows the start of the gradual change control is relatively lower than the rate of increase of the pixel value in the second period subsequent to the first period.
