Abstract
An automotive heads-up display (HUD) calibration system includes a back-lit HUD system of an automobile, the back-lit HUD system being configured for full array local dimming (FALD) via a plurality of independently-controlled back-lit regions, and a computing system configured to optimize a set of graphics for projection by the back-lit HUD system to reduce energy consumption by the FALD control of the back-lit HUD system, where the computing system is an external computing system that is only associated with the back-lit HUD system temporarily in a calibration environment.
Claims14
An automotive heads-up display (HUD) calibration system, the automobile HUD calibration system comprising:
- a back-lit HUD system of an automobile, the back-lit HUD system being configured for displaying graphics on a surface of the automobile via projection and full array local dimming (FALD) via a plurality of independently-controlled back-lit regions;
- and
- a computing system configured to:
- obtain a non-optimized set of graphics for display by the back-lit HUD system, perform an energy consumption analysis of the back-lit HUD system for projection and FALD of the non-optimized set of graphics, and, based on the energy consumption analysis, optimize the non-optimized set of graphics to obtain an optimized set of graphics for display by the back-lit HUD system, wherein the computing system is an external computing system that is only associated with the back-lit HUD system temporarily in a calibration environment,
- wherein the back-lit HUD system is further configured to receive and store the optimized set of graphics and to control the projection and FALD of the optimized set of graphics, and wherein the projection and FALD of the optimized set of graphics requires less energy consumption compared to projection and FALD of the non-optimized set of graphics.
A calibration method for a back-lit heads-up display (HUD) system of an automobile, the calibration method comprising:
- providing the back-lit HUD system, the back-lit HUD system being configured for displaying graphics on a surface of the automobile via projection and full array local dimming (FALD) via a plurality of independently-controlled back-lit regions;
- obtaining, by a computing system, a non-optimized set of graphics for display by the back-lit HUD system;
- performing, by the computing system, an energy consumption analysis of the back-lit HUD system for projection and FALD of the non-optimized set of graphics;
- and
- based on the energy consumption analysis, optimizing, by the computing system, the non-optimized set of graphics to obtain an optimized set of graphics for display by the back-lit HUD system to reduce energy consumption by the FALD of the back-lit HUD system, wherein the computing system is an external computing system that is only associated with the back-lit HUD system temporarily in a calibration environment,
- wherein the back-lit HUD system is further configured to receive and store the optimized set of graphics and to control the projection and FALD of the optimized set of graphics, and wherein the projection and FALD of the optimized set of graphics requires less energy consumption compared to projection and FALD of the non-optimized set of graphics.
